THINK vinc. released electrical generator for emergency “MGV”, usable in the room, for longest period ever.

(Source: ALUTOPIA, April, 2019)

THINK vinc. (Minato-ku, Tokyo) is selling electrical generator for emergency “MGV”, usable in the room, for longest period ever.  Existing magnesium air battery had overwhelmingly insufficient capacity of “positive electrode”, which received electricity generated by magnesium.  By using specially processed carbon positive electrode, “MGV” accomplished to generate 100 W×48 hours.   LED stand type lighting 10W x 1, mobile phone 5W x 2, Laptop 40W x 1,  20-inch LCD TV 40W x 1, all of which can work at the same time.

There are 5 main features:

  1. 10 times more amperage than competitive products. 
  2. Maintenance-free even for long storage since no deterioration happens.
  3. Usable anywhere due to noiseless and odorless.
  4. Strageable at anywhere since no charging is required. 
  5. Contemporary design fitting even in office.  

Specification is as follows; Size : 725mmH x 675mmW x 500mmD.  4.8kWh, Max power 100W,  48 hours working continuously (at rated output 80W),  AC Output port: AC x 2,  Weight: 45 kgs (Not including salt water weight), moving on casters,  Cell: exchangeable cartridge type and 10 years lifetime.

The company started free seminar campaign regarding required knowledge for emergency preparedness only for MGV purchasers.

Is next Apple iPhone flip type? Patent documents are unveiled.

(Source: Forbes Japan, April 6, 2019)

It is unveiled that Apple Inc. is planning to release iPhone with very impulsive design.  While Huawei and Samsung had released foldable display type on the market, Apple Inc. is developing one looks like old flip type feature phone.

Patent application documents appeared in news site Patently Apple, include picture of twice-folded mobile phone, which shows one side is display and the other is keyboard.  2 names, Kevin Robinson of Apple’s product engineer and Houtan Farahani of senior product design engineer, are listed as inventor.  This patent refers to not only design but also material.  Apple realizes lightweight and foldable device by means of combining titanium/magnesium layer and various plastic (Polyethylene terephthalate, Polyvinylchloride and Polyisocyanurate form).  At a glance, it looks like just a feature phone but this device is manufactured by very complicated material combination.

The question arises why feature phone now.  However, while Huawei and Samsung adopted foldable device with plastic display, Apple prefers material capabilities and applies extended patent to enable to fold by heat inside display.

Magnesium is applied on body and frame.  And titanium is applied on propeller, which contributes to weight saving. In addition, surface is coated by zirconia which performs heat resistance up to 2,000 degree. Lens is covered by quartz to protect against heat. Fire proof cover guards battery and motor. Same battery is used as existing type.

At early stage of development, test was carried out by using existing method i.e. heat resistant painting on carbon body, however it failed to equip sufficient fireproof performance.  It was hard to decide which material to choose for body, propeller and painting. Moreover an issue arose on sufficient zirconia paintability even after material was decided. To resolve such issues, 2 solutions are chosen, (1) surface treatment which makes zirconia-coating easily (2) press-tooling improvement of body, frame and propeller.

Kobe Steel raised aluminum rolling price due to cost increase of auxiliary raw material and transportation.

On April 10, Kobe Steel, Ltd. announced to raise aluminum rolling product price for both can-lid and automobile. 

Processing cost (rolling margin) is raised by 10% from June delivery on. Cost increase of both auxiliary raw material and transportation are reflected.

Price Raise is the first time since January 2015 after 4 years and 5 months interval.  Aluminum rolling product price is calculated by adding processing cost on aluminum metal price.  Magnesium is rare metal used as auxiliary raw material, whose supply from China decreased due to factory operation stop caused by governmental environmental regulation last year.

Ishikawa Energy Research released long time flight surveying drone adopting magnesium alloy.

(Source: The Nikkan Kogyo Shinbun, April 10, 2019)

Ishikawa Energy Research Co., Ltd (Oota-shi, Gunma Pref.) has developed drone for both surveying and aerial photography, which is able to fly around for more than 50 minutes by just one time charging. Magnesium alloy is applied on body to enhance stiffness and save weight.  Price is 900,000 JPY (without tax) including battery charger. It is planned to release in coming October and is targeted 200 sets sales per year.

Newly developed drone “Build-flyer” performs on both superior durability and restraint strength deterioration under long time ultraviolet ray exposure, by using magnesium alloy.  Both reconsideration of individual parts and enhancement of battery capacity, lead to accomplish 2 times longer flight duration than competitor’s one. Camera and laser surveying machine can be mounted on body.  In case of carrying 5 kg lord, 30 minutes flight is possible. Various uses are expected such as agricultural use like plant growth monitoring as well as surveying, aerial photographing and inspection.

Legs move up in flat during flight, which enables to take pictures widely.  Arms are retractable, which contribute to easy carrying.

Fujikura Composites started receiving reservation of home use magnesium air battery.

(Source: Japan Chemical Daily, April 18, 2019)

Fujikura Composites Inc. expands magnesium air battery business.  New product for home use, “AQUA Charge”, started to receive a reservation through website.  Delivery will be scheduled after May 29.  Just pouring water on attached salt to make a salty water and putting electric cells in it, then generation starts, which simplicity is the point.

Aqua Charge is upgraded product, successfully developed performance adequacy for downsizing and safety assuming home use, added on proprietary technology cultivated by WattSatt development.  The company will look for supply chain to general consumers and corporations as emergency battery in offices.  In addition, they plan to develop new product and expand product lineup.  Size is 104 mm H x 95 mm D x 105 mm W.  Weight is 525 gram.  Recommended retail price is 4,980 JPY (without tax).

Tohoku University developed prototype of “Oral clinical thermometer”, 24 hours health care by IT.

(Source: The Nikkei, April 26, 2019)

The future is approaching, when health condition is monitored by “IoT”, all things connect to Internet.  Various sensors catch disorders of physical condition, which is useful for health care and disease prevention. The team of Tohoku University is developing unique device to realize new daily life as if being monitored by thorough medical examination every day.  Firstly they developed a prototype of “Oral clinical thermometer” to measure inside deep body.  In 2030’s the life surrounded by many sensors might be quite natural.

This thermometer looks like tablet. The size is 9 mm in diameter and 7 mm in thickness. Reaching stomach after oral input, electric charging starts after that gastric acid reacts with electrode. Moving down to intestine, body temperature is measured every 30 minutes and the data is wired to outside body.  Magnesium and platinum electrodes are laid on one side and both condenser and coils for wireless communication are placed inside. Generating method is as simple as the one to stick electrodes into lemon.  

This is one of “the Center of Innovation Science and Technology based Radical Innovation and Entrepreneurship Program”, planned by Ministry of Education, Culture, Sports, Science and Technology, which is carried out until 2021.  Followed by experiment on pig, clinical study for 5 to 10 years is intended jointly with large-scale hospitals.  Researchers who is studying relationship between biological clock abnormality and clinical depression, are long awaiting practical use.

Dr. Tsutomu Nakamura, Specially appointed professor of Center for Promotion of Innovation Strategy, said that it would be in good shape within 3 years.
