Yamagata University and other – Developed sensor which performs high-speed response to short wavelength UV
(Source:The Nikkan Kogyo Shimbun, 26 Sep. 2017)
Yuta Matsushima, Associate professor and Daisuke Fukushima postgraduate, both of Graduate school of Science and Engineering, Yamagata University developed a sensor which performs high-speed response to short wavelength UV, jointly with NEC Embedded Products, Ltd.
It uses a principle that conductive electron is generated and electrical resistance changes by shining ultraviolet light on zinc oxide film. This response is so rapid at 10 millisecond that it enables identification of ultraviolet wavelength range. The advanced applications are expected for fire alarms which detect flame, and beauty equipment which distinguishes the kind of ultraviolet rays.
Zinc oxide film is formed on Glass substrates, all of which is covered by electrode film with a space. When ultraviolet rays shine on zinc oxide, conductive electron is generated after zinc ionizing. The distance between electrodes is 20 µm. Response speed is improved by adjusting zinc oxide to generate electron easier. Conventional zinc oxide sensors took several seconds to respond. Furthermore it was found that the ultraviolet ray response wavelength is controllable by adding magnesium in zinc oxide.
While additive-free zinc oxide reacts only to 380 nanometer wavelength, magnesium added one is able to react to high energy 315 nanometer, which means wavelength can be distinguished according to magnesium presence. Since flame contains mainly high energy UV, UV from lightning can be distinguished easily. The issue was zinc oxide reacted to moisture in the air just after zinc was ionized. The point was to prevent deterioration by covering zinc oxide with electrode film which attracts electron more than moisture. Practical use is anticipated in 2018.

Tsukuba Diecasting Co., Ltd. will acquire Quality control international standard IATF16949（Ver.2016 revised in October 2016) at both Tono and Miyagi factories in June 2018, instead of ISO/TS16949. Furthermore largest-ever 1,250 ton diecast machine will be equipped in Miyagi factory, the magnesium production base. The existing maximum size is 1,000 ton and 800 ton for aluminum and magnesium respectively, new largest 1,250 ton will cope with large size parts demand.
A total of 13 machines for magnesium from 150 to 1,250 ton are equipped. While lightweight trend is accelerating in aluminum application, magnesium demand is still in the back and forth. However, monthly magnesium parts production reaches 170 ton per month, which is growing almost to the 200 ton level of aluminum. Miyagi factory was established in 1998 which has produced IT, AV and optical devices and automotive parts by integrated process from casting to painting.
New processing development is also carried out such as hybrid process (ultra thin wall magnesium housing + plastic insert molding). There is magnesium production overseas based in Hungyen, Vietnam which is the first magnesium diecast factory in Vietnam and producing ultra thin wall products and complicated shape products keeping same quality as Japan, by integrated system as above - leading magnesium production complex in Southeast Asia.
Domestic Magnesium Market - August, 2017
(Source: August issue of Import/Export Statistics (customs clearance basis) of METI. Compiled by The Japan Magnesium Association.)
Based on Import/Export Statistics of August 2017, magnesium metal import was total 3,006.7 tons,
29.9% significant decrease on month-to-month basis (13.7% increase from the same month previous
year), which decrease was due to high volume imported in previous month however managed to
keep level of 3,000 tons. Magnesium powder was 403.5 tons, 3.5% decrease on month-to-month
basis, decreasing for consecutive 2 month however relatively high (23.4% increase, stable).
Other products had regained in July after significant decrease in June however it decreased down to
186.8 tons, 44.9% decrease on month-to-month basis (33.7% decrease), which decreased to 100tons
level while it had kept 200tons level until March. Total was 3,596.9 tons, 20.9% decrease on
month-to-month basis (10.6% decrease).
The metal category consisted of 4 products as follow:; a) 2,330.1 tons of pure magnesium, 20.7% or 1,000tons significant decrease on month-to-month basis (15.6% increase).
