Title: Hologram recording material
Inventor: IMAI YOSHIYUKI
IPC: G02B5/32
Filed: 1995-08-24
Abstract: PURPOSE: To provide a hologram recording material comprising potassium tantalate niobate in which a hologram can be fixed by incorporating hydrogen ion into an electro-optical crystal comprising potassium niobate tantalate. CONSTITUTION: When a single crystal is grown from a fused liquid of oxides of tantalum, niobium, potassium, and the like, the fused liquid is made to react with hydrogen gas or water vapor so as to add hydrogen ions to the single crystal of potassium tantalate niobate. Two laser beams 3, 4 making 20 degree angle from each other are made to enter a hologram recording material comprising potassium tantalate niobate containing hydrogen ions to form space charges by electrons or holes. The crystal is subjected to heat treatment to move the hydrogen ions to compensate the space charges. Then the crystal is cooled to room temp. and irradiated with homogeneous light. Since hydrogen ions hardly move at room temp., the space charges by hydrogen ions remain as a replica.

Title: Stock for photosensitive drum made of aluminum alloy having high precision machinability and its production
Inventor: AIURA SUNAO
IPC: G03G5/10
Filed: 1986-09-11
Abstract: PURPOSE:To produce a stock which permits precision machining at a low cost and decreases defects at the time of cutting the film by the constitution consisting in suppressing the max. diameter of crystallized matter to <=5mu in average, the number thereof to <=2,000 pieces/mm<2> and unavoidable impurities to <=3,000ppm. CONSTITUTION:The cooling rate in the central part of an ingot is maintained at >=2.5 deg.C/sec in order to maintain the max. diameter of the crystallized matter to <=5mu in average and the number of the crystallized matter to <=2,000 pieces/mm<2> by increasing the solidifying rate of an aluminum alloy after casting thereof, by which the gouging and scratching of the crystallized matter by the machining defects and film forming defects are suppressed. A soaking treatment at 500-615 deg.C is executed in order to decrease the Fe impurity to <=3,000ppm. The decrease of the crystallized matter to <=5mu is not possible if the impurity exceeds the upper limit. An extrusion ratio is set at >=10 to crack and diminish the large crystallized matter at the time of hot extrusion. The precision machining is, therefore, possible at a low cost and the defects are decreased even if the film is formed on the surface.
