Title: Method for refining copper alloy
Inventor: YAMADA HIROYUKI
IPC: C22B9/20
Filed: 1982-06-18
Abstract: PURPOSE:To refine a Cu alloy contg. a specified element dispersed uniformly in a high yield by primarily melting Cu and said element in an inert gas, casting the molten alloy, and finally melting the casting as an electrode in an inert gas in a consumption type vacuum arc furnace. CONSTITUTION:To Cu or a Cu alloy is added a desired amount of >=1 kind of element selected from the elements belonging to the IIIb, IVa, IVb, Va and VIa groups, and they are primarily melted in a furnace. The melting is carried out under 1atm or reduced pressure by feeding an inert gas to the furnace. The resulting molten alloy is cast, and the casting is melted again once or more as an electrode in a consumption type vacuum arc furnace.

Abstract: PURPOSE:To decrease long-wavelength side sensitivity and allow light to strike a semiconductor substrate from both top and reverse surfaces by reduing the thickness of semiconductor substrate parts as a light incidence part of a semiconductor where a picture element cell is formed. CONSTITUTION:When the substrate 40 is 200mum thick and a high-resistance n<-> layer is about 6mum thick, the thickness l1 of the substrate corresponding to areas as light incidence parts is decreased to cut the long-wavelength side sensitivity to desired wavelength.

When an element having such structure that the substrate thickness l1 is decreased is manufactured, respective areas on the side of a gate electrode 6 are formed firstly. Then, a high-resistance substrate opposite to the gate electrode 6 is removed by selective etching technique to form a source electrode 10.

Title: Method for stabilizing characteristic of electrophotographic sensitive body
Inventor: ASAMURA ATSUSHI
IPC: G03G5/08
Filed: 1983-06-13
Abstract: PURPOSE:To stabilize the characteristics of an electrophotographic sensitive body in a short time and to improve the corrosion resistance by depositing a selenium-base material on an electrically conductive substrate to form a photosensitive layer and by immersing the resulting sensitive body in boiling pure water to carry out heat treatment. CONSTITUTION:An Se-base material is vacuum-deposited on an electrically conductive substrate of Al or the like to form a photosensitive layer. After the lapse of 24hr, the resulting sensitive body is immersed in boiling pure water (distilled water) for 30-60min, and it is taken out and dried. The electric potential after electrostatic charge changes largely until the sensitive body is immersed for 30min, and when the potential after the lapse of 10 days after the vacuum deposition is considered to be 100, the potential attains to 95% by immersion for 30min. The whole sensitive body is uniformly stabilized, and a boehmite film is formed on the exposed Al surface to improve the corrosion resistance. Conventional preservation in the dark for 10 days or repeated electric charge and discharge for accelerating stabilization are not required, and an ultraviolet-ray irradiator or other apparatus is made unnecessary.
