Title: P-type iii nitride compound semiconductor and its production
Inventor: ASAZUMA YASUNORI
IPC: H01S5/323
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To improve crystalline property and electrical conductivity and to uniformize a composition ratio in the growing surface of crystal and p-type impurity concentration. SOLUTION: Plural 1st layers 11, each of which consists of AlGaN mixed crystal and has about 1 to 100 nm thickness and plural 2nd layers 12 each of which is Mg-added p-type GaN and has about 1 to 100 nm thickness, are laminated alternately. Since respective layers 11, 12 are thin, the laminated layers as a whole have properties of a p-type AlGaN mixed crystal, even when Mg is not included in the 1st layers 11 and Al is not included in the 2nd layers 12. Since an Al material and a Mg material are supplied so as to be timewisely separated, reaction between the Al material and the Mg material which interfere with the growth of fine crystal can be prevented. Thereby fine crystals can be allowed to grow.

Title: Power source unit
Inventor: HIBINO MASAAKI
IPC: H02J3/00
Filed: 1987-05-30
Abstract: PURPOSE:To reduce power consumption, by disabling a forcible discharge circuit upon throw-in of A.C. power source. CONSTITUTION:Upon closure of a source switch 1, an AC power source 2 is thrown in to feed AC power which is converted into a predetermined D.C. voltage and fed to an electronic control circuit 6. 60Hz A.C. signal is inputted through a transformer 3 to CPU7, and a zero-cross detection circuit 8 detects the level of the AC power source 2 on the basis of that signal and outputs pulses. Since the CPU7 judges throw-in of AC power source 2 from the output pulses and produces a low level signal from the output side, a transistor 10 is turned OFF and no current flows through a resistor 9. Consequently, useless power consumption in the resistor 9 can be prevented, resulting in reduction of power consumption.

Title: Optical beam scanner
Inventor: ASANO EIJI
IPC: B41J2/44
Filed: 1981-08-29
Abstract: PURPOSE:To obviate the deviation of a beam which scans on an x-axis to a y-axis direction even when a rotary polyhedral mirror inclines by using the rotary polyhedral mirror disposed with plural sets of mirrors consisting of 2 pieces having lines of intersection on the plane intersecting orthogonally with a revolving shaft on the same circumference centering at the revolving shaft. CONSTITUTION:A rotary polyhedral mirror 3 is constituted of 8 sets consisting of 2 pieces (a), (b) intersecting with each other at an angle theta. Incident light 2 is reflected from one of two pieces a set of the mirrors to the other and is made into exit light 2'. When the mirror 3 is viewed from the side surface, the angle that the light 2 and the light 2' assume is 0 deg., that is, parallel when, for example, the angle theta of intersection is 90 deg.; therefore, if the parallel luminous fluxes are converged with an imaging optical system 6, the incident angle is immobile even when the mirror 3 is mounted to the shaft 1 with inclination by the angle theta (because the light source device does not move), whereby the scanning in the direction vertical to the plane of the figure is performed without deviation of the converging point O of the parallel luminous flux.

Title: Manufacture of semiconductor device
Inventor: ADACHI HIROKI
IPC: H01L21/20
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To manufacture a thin film semiconductor element having excellent characteristics with a high yield. SOLUTION: After a base film is formed by using a glass substrate of Corning 7059, etc., as a substrate 101, the substrate 101 is annealed at a temperature higher than the strain temperature (strain point) of the substrate 101 and gradually cooled to a temperature lower than the strain point. Thereafter, a thin film semiconductor element, such as the TFT, etc., is manufactured by forming a silicon film 104. When the substrate 101 is annealed at the temperature higher than the strain point and gradually cooled after annealing, the substrate 101 does not shrink much during the course of the succeeding heat treatment. Therefore, the yield of the semiconductor element is improved, because mask alignment can be performed easily and the occurrence of defects, etc., caused by deviated masks is reduced.  In addition, the TFT characteristics of the semiconductor element are improved, because the interfacial characteristic of the base film is improved by the annealing.

Title: Semiconductor device
Inventor: TAKENAKA NOBUYUKI
IPC: H01L29/78
Filed: 1985-06-21
Abstract: PURPOSE:To reduce the resistance value of an N<-> layer, by forming a low-concentration impurity diffused layer having a reverse conducting type with respect to a semiconductor substrate at a lower part of a side wall on one side, and forming a high- concentration impurity diffused layer having the same impurity as that in the low- concentration diffused layer at a lower part of a side wall on the source side. CONSTITUTION:On a P-type 100 substrate 1, a gate oxide film 2 is formed. A polysilicon film is formed. Phosphorus is doped by thermal diffusion. Then, with a photoresist film 7 as a mask, anisotropic etching is performed. Thus a gate electrode 3, whose side surface is approximately vertical is formed. With the gate electrode 3 as a mask, phosphorus is implanted in the silicon substrate at a slant angle of about 10 deg. to the drain side. The phosphorus-ion implanted layer is formed so that the layer is separated from the end part of the gate electrode. An oxide film 4' is formed by a plasma CVD method. Thereafter, anisotropic etching is performed until the surface of the silicon substrate 1 is exposed, and a side wall 4 is formed. Arsenic is implanted at a slant angle of about 10 deg. to the source side, which is opposite with respect to the phosphorus-ion implanting direction. Thus, the arsenic-ion implanted layer is formed. Therefore, suppression of a hot carrier effect and the suppression of increase in channel resistance can be simultaneously realized.

IPC: C07C29/88
Filed: 1978-11-06
Abstract: PURPOSE: To prepare a highly pure t-butyl alcohol in high yield, by hydrating an isobutylene-containing hydrocarbon mixture, removing the unreacted hydrocarbons from the reaction mixture, and extracting and distilling the residual reaction mixture using water as the extracting agent, thereby separating the by-produced esters.  
     CONSTITUTION: Isobutylene or an isobutylene-containing hydrocarbon mixture is reacted with an aqueous solution of a 1W6C aliphatic carboxylic acid in the presence of an acidic ion exchanger under the condition that the reaction solution becomes homogeneous. The unreacted hydrocarbon mixture is removed from the reaction solution by conventional distillation and thereafter the ester of t-butyl alcohol is separated from the residual reaction solution by the extraction distillation using water as the extracting agent. The bottom of the extraction distillation is separated to t-butyl alcohol and an aqueous solution of the organic acid by conventional distillation and the organic acid is recycled to the hydration reaction. The ester separated by the extraction distillation is hydrolyzed by contacting with a strongly acidic ion exchange resin and fed to the recovering site of the extraction distillation column.

Title: Structure of armature of flat motor
Inventor: TEZUKA TAKETOSHI
IPC: H02K7/06
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To decrease the number of coils constituting an armature, simplify the manufacturing process, and reduce the manufacturing cost by providing the armature with a magnetic body, and allowing the magnetic body to be located on the boundary between an N pole and an S pole of a magnet when stopping the rotation of the armature so that a coil can be excited. SOLUTION: A magnet 21 is a disc which is equally divided into four parts and magnetized in an N pole and an S pole alternately, and rotatably supports the most important section 13 of the armature at its center. When an armature 10 is rotated clockwise or anticlockwise on the magnet 21 and, after that, the power being supplied to a coreless coil 12 of the armature 10 is turned off, the armature 10 stops with the center in the longitudinal direction of an iron pin 20 being located on a boundary line 22 between the N pole and the S pole of the magnet 21. At that time, one side 12a of the coreless coil 12 largely overhangs the S pole beyond a region Z on the magnet 21 where it is said that the armature 10 can hardly start up, and therefore the armature 10 can be smoothly rotated when it is started up.

IPC: G05D3/00
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To provide a position controller for a ball screw drive system that fast controls the dynamic flexion, i.e., the deviation caused between a motor position and a table position in an acceleration/deceleration operation mode and controls the table position with high accuracy in response to the position command value. SOLUTION: The parameter of a ball screw drive system is decided based on the position command value X, the acceleration command value A, the torque command value τc and a motor velocity vm. Based on this parameter, a compensation value decision part 2 calculates the dynamic flexion value that is caused in an acceleration/deceleration operation mode. A compensation command part 1 includes the part 2 to output the compensation value Xdf, which compensates the dynamic flexion value, the flexion velocity value Vdf and the vector compensation value τdf. In such a constitution, those output compensation value are properly added to every part of a position controller.
