Title: Manufacture of semiconductor device
Inventor: ISOZUMI SHIYOUJI
IPC: H01L33/30
Filed: 1978-12-28
Abstract: PURPOSE: To obtain a uniform curved surface by providing a Ga 1-y Al y As layer between a GaAs substrate, in which a curved surface is formed, and Ga 1-x Al x As layer which is grown on the substrate and the chemical property of which is different from that of said layer to be provided and by controlling its thickness.  
     CONSTITUTION: The lens-shaped holes 31A are selectively formed in the GaAs substrate 31. The size and depth of holes can be made less than the radius of curvature of the desired lens-shaped radiation end face. The Ga 1-y Al y As layer 32 is epitaxially liquid-grown, the holes 31A are embedded and the growth is stopped before the holes become flat. The growth rate of the layer 32 has no anisotropy, but the component ratio y of Al is made different from that x of Al of the Ga 1-x Al x As layer 33, which is to be grown in the next step, to make the selective etching possible. If x≈y, the GaAs layer 32 is provided between both layers 32, 33. The layer 33 is grown to the desired thickness and the surface is made flat. When the substrate 31 and layers 32, 32' are etched, the desired lens-shaped radiation end face 33 of a uniform radius of curvature can be obtained.

Title: Laser thermal transfer recording material and method for laser thermal transfer recording
Inventor: MORIZUMI DAIGO
IPC: B41M5/26
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To rapidly record by preventing a damage of a photothermal conversion layer itself by a laser beam and clarifying a recorded image. SOLUTION: In the laser thermal transfer recording material obtained by sequentially laminating a photothermal conversion layer containing at least a near infrared absorption material and an inorganic binder as main bodies, and a thermal transfer ink layer in this order on a base material; a metal oxide is used as the binder to raise a thermally decomposing temperature, and hence the conversion layer becomes excellent heat resistance. Further, the binder can give higher thermal conductivity than that of a resin material to perform high sensitivity. Since the oxide is formed via a polycondensation of a metal hydroxide of a solution state, the conversion layer has excellent adhesive properties with the base material to become a high strength.  Moreover, since the binder is a non-thermoplastic binder, a decrease in its sensitivity is not brought about by raising durability of the ink layer softened at the time of heating, but printing of high sensitivity can be conducted.

Filed: 1982-09-25
Abstract: PURPOSE:To eliminate inconvenience and to prevent a change in automatic shut- off time even when wrong key operation is performed, by setting the automatic shut-off time or display clear time optionally on a ten-key numeric pad consisting of numeric keys. CONSTITUTION:A copy quantity display device 53 displays ''1'' three minutes after an electric power source is thrown in and then while copy conditions such as the number of copies can be inputted, the automatic shut-off time is set optionally with the ten-key. When the automatic shut-off time is counted, an H- level signal is outputted from the terminal 1 of a port C of a microcomputer Q1 and a switch SW1 is turned off to disconnect the driving power source. When the input voltage to the terminal 1 of a port D drops to a level L, the disconnection is detected and the microcomputer Q1 clears the copy conditions, etc., stored in an RAM and also clears respective displays to return to the initial state. Therefore, normal key operation is only performed a specific time later and a change in automatic shut-off time due to misoperation of the key is prevented.

Filed: 1987-07-02
Abstract: PURPOSE:To enable the generation of inclined characters such as italics using a font for a base face, by a method wherein a writing-start position register and a select register are made of upper and lower bits of a counter counted in relation to a writing end signal for one line of a character image. CONSTITUTION:A writing-start position of character image data on an image memory is determined by a writing-start position register 21 by every two or more dots forming one set of data. On the other hand, by every aforesaid dot unit a shift amount per line of the character image data in a width direction is determined by a select register 50. In relation to a writing-end signal for one line of the character image, a counter 51 is counted, and the information in the select register 50 forming lower bits of the counter 51 is increased/ decreased. When this value reached a fixed value, the information in the writing- start position register 21 forming upper bits of the counter 51 is increased/ decreased. The character image is inclined by successively changing the information in these registers.

Abstract: PURPOSE: To provide a keyboard pad provided with all desirable properties including excellent elasticity and an excellent bending life by using the blend of the terpolymer (EPDM) of ethylene propylen dien monomer and the copolymer of propylene oxide and allyl glycidyl ether. CONSTITUTION: When parelan copolymer is added to the EPDM, the elasticity of this pad is practically improved without adversely affecting the bending life of the pad.
