Title: Semiconductor device
Inventor: OOMURA KAZUMICHI
IPC: H01L29/78
Filed: 1981-11-30
Abstract: PURPOSE:To obtain high electron mobility of a semiconductor device by forming an insulated gate FET so that the electron running direction becomes parallel to the specific crystal surface in a 001 Si layer formed on an insulating substrate. CONSTITUTION:An SOS substrate 3 which is formed with a P type Si film 2 is prepared on a sapphire substrate 1. An SiO2 film 4 is formed on the substrate 3. Then, the layer 4 and the film 2 are selectively etched to expose the 100 crystal surface. Subsequently, a gate oxidized film 5 is formed on the exposed 100 crystal surface. Thereafter, p-doped polycrystalline Si 6 is accumulated on and on the surface of the film 5. Then, it is etched except a polycrystalline gate 8. Thereafter, with the gate 8 as a mask ions are implanted, thereby forming N<+> type source and drain at both sides of the gate 8. When an MOSFET is formed in this manner, the electron run between the source and the drain becomes parallel to the 100 crystal plane, thereby obtaining high electron mobility. Even when 010 crystal surface is used, high mobility can be also obtained similarly to the case of employing the 100 crystal plane.

Abstract: PURPOSE:To prepare easily the titled alloy having a uniform composition, by heat sinking a low-melting material sealed in an inner tube, and quenching a melt of a material for forming an alloy containing an easily evaporable component in an outer tube. CONSTITUTION:A material 4 for forming crystals of Hg1-xCdxTe (the easily evaporable component is Hg) is contained in an outer tube 1, and Te (low-melting material) 5 is contained in an inner tube 2. The insides of the tubes 1 and 2 are evacuated, and the ends of the respective tubes 1 and 2 are fused and sealed (numeral 6 indicates a quartz rod simultaneously fused to the ends). The resultant assembly is then hung in a heating furnace to melt the respective materials 4 and 5 and give a melt (4A) of the material for forming an alloy and a melt (5A) of the low-melting material. The resultant melts (4A) and (5A) are then quenched to form an alloy consisting of Hg1-xCdxTe in the outer tube 1. The temperature drop of the top of the outer tube 1 is moderated by the heat capacity of the melt of Te in the inner tube 2 according to the above-mentioned method, and the evaporation of the Hg which is the easily evaporable component to the top of the outer tube 1 is prevented. Thus, the alloy of uniform composition is easily obtained.

Title: Data restoring system
Inventor: CHIBA HIROTAKA
IPC: H03M7/46
Filed: 1990-07-18
Abstract: PURPOSE:To shorten the time required for a restoring processing by restoring plural codes formed by an increment decomposing type Ziv-Lempel coding system in parallel. CONSTITUTION:In the case of restoring compressed data obtained by compressing a character string by the increment decomposing type Ziv-Lempel coding, plural codes continuously inputted by an input means 131 are outputted in parallel and inputted to plural decoding means 121. Each decoding means 121 refers to a registered information storing means 112, and at the time of completing the registration of a code concerned, executes decoding processing independently of the decoding state of the immediately preceding code. Thereby, codes already registered in a dictionary 111 can be decoded in parallel. Consequently, the time required for the restoring processing of compressed data compressed by the Ziv-Lempel coding can be shortened.

Title: Finish processing method for sintered metal via electrochemical machining
Inventor: KUWABARA YOHEI
IPC: B23H3/00
Filed: 1987-07-30
Abstract: PURPOSE:To ionize even a parent metal in addition to a bonding material for sintered metal and obtain a glossy surface by supplying pulse current of specific current density between a workpiece and a processing electrode in processing the workpiece comprising sintered metal. CONSTITUTION:An electrolytic product generated by filling a machining fluid free from an electrolytic product between a processed surface 2a and an electrode surface 4a opposing a gap 18 and supplying pulse current, is eliminated and the electrode surface 4a is again made in contact with the processed surface 2a. Processing depth per processing is measured and a value obtainable therefrom is accumulated. The aforementioned process is repeated with a control device 12. The process terminates when the accumulated value reaches within the predetermined difference, compared with a set value calculated by a processing condition control part 10 on the basis of data from an input device 13. When pulse current of low current density is fed in finishing sintered metal, only a metal composition liable to being eluted depending upon ionization tendency is eluted. By supplying the pulse current of current density equal to or above 110A/cm<2>, surface roughness is improved regardless of the ionization tendency of the metal composition.

Filed: 1992-06-26
Abstract: PURPOSE:To maintain stable printing quality for a long time by providing a dummy channel filled with elastic filler between two partition walls whose faces opposite to opposing faces of adjacent two partition walls face an ink passage channel. CONSTITUTION:Partition walls 5aa, 5ab, 5bb, 5bc... of piezoelectric raw material are fixed on a substrate 1 in parallel. A large number of slender channels formed among the partition walls are channels 2a, 2b, 2c and dummy channels 12a, 12b of an ink chamber/passage alternately. The channels 2a, 2b, 2c of the ink chamber/passage are connected to a common ink reservoir by each one end, and other ends are stuck to a nozzle plate having nozzle holes 3a, 3b.... The dummy channels 12a and 12b are filled with an elastic filler 6 so as to separate ink between the adjacent channels of the ink chamber/passage. When electric potential which is positive with respect to an electrode 4ab is applied to an electrode 14ab, ink drops are discharged from the nozzle hole 3b by deformation of a shearing mode of the partition wall 5ab. At this time, the elastic filler 6 of the dummy channel is easily deformed as the compressibility is large.

Title: Driving method of discharging device
Inventor: SHINADA SHINICHI
IPC: H05B41/24
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To improve light emitting efficiency by specifying the frequency of a second voltage superposed on a first voltage. SOLUTION: Voltage V1, V2, each produced by superposing a first voltage having a first frequency on a second voltage having a second frequency higher than the first frequency, are applied to electrodes 21, 22 of a discharge tube 20. The first voltage having the first frequency is applied to the discharge tube 20 so that discharge is caused by the voltage. Next, when the second voltage having the second frequency is superposed, electrons, ions, and plasma already formed and present in the discharge tube oscillate along with changes in the electric field. When the second frequency is chosen in the range of 2.4-20MHz, further a resonance phenomenon of electrons, ion and plasma is also generated.  As a result, temperature of these particles rises and electron temperature approaches a value preferably for radiating visible light or ultraviolet rays, and light emitting efficiency is improved.
