Patent JP-2001035793-A (JP)
Title: Manufacture of compound semiconductor device
Inventor: MEGURO TAKESHI
IPC: H01L21/205
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a compound semiconductor device having superior electrical characteristics. SOLUTION: Hydrocarbons are decomposed thermally in a reaction tube, and radicals are generated. These radicals are reached with an n-type impurity (for example, silicon) which are attached to a surface of a compound semiconductor substrate, and organic silicon is generated. This reaction is reversible, but almost no organic silicon exists in a vapor phase. The organic silicon itself has very high steam pressure, as compared with silicon single body. Therefore, the organic silicon is removed from the compound semiconductor substrate 3 along with gas flow. Thus, contamination due to an n-type impurity at an interface between the compound semiconductor substrate 3, and a buffer layer 2 can be reduced in a well-controlled manner.

Title: Variable compression ratio device for internal combustion engine
Inventor: MORITA SHUJI
IPC: F02B75/04
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To avoid generation of sliding resistance on a driving system between an eccentric bearing and a crank pin, and between an actuator and the eccentric bearing by forming the actuator in a crank shaft or fixing the actuator to the crankshaft.

It is also possible to avoid generation of the sliding resistance between the eccentric bearing 37 and an actuator gear 36 for driving connecting the actuator 31 and the eccentric bearing 21 to each other in association with rotation of the crankshaft 11.

Title: Image reader
Inventor: FURUMURA MASAKAZU
IPC: F16H7/12
Filed: 1991-08-15
Abstract: PURPOSE:To prevent blank paper information from being read by erroneous insertion of the paper surface to a picture input device by providing an image reader which detects whether the input page of the document is a blank paper or not and reads the rear side of the input document in the case of a blank paper and outputs picture information on the rear side at the time of detecting information on the rear side. CONSTITUTION:The paper surface on one side of a transmission document inserted to a document insertion hole 11 is read by an image scanner 15; and if it is judged that the whole of the paper surface is a blank paper, a subroller 18 is reversed to read the opposite side of this read paper surface. Thus, the blank paper surface is prevented from being unnecessarily read to output only paper surface information effective as picture information.

Title: Method and apparatus for automatic analysis on degrading of leaf tobacco
Inventor: RICHIYAADO EMU HENDASON
IPC: A24B3/18
Filed: 1990-08-03
Abstract: PURPOSE: To automatically analyze the degree of deterioration by separating samples of specific weight of a tobacco material into fractions of leaf tobacco pieces of different size and particulate fractions, and scaling and analyzing them according to the weight distribution. CONSTITUTION: A sampling means collects samples from a tobacco process line and supplies them to a scaling conveyor 28 to generate a signal which is proportional to the weight of the samples. A multi-screen vibratory separating machine 14 receives the samples from the scaling conveyor 28 and separates the samples into tobacco fractions of different size through a 1st screen. Further, a cleaning brush automatically cleans the residues of the samples from the top and reverse surfaces of the screen and a collecting and scaling means collect respective tobocoo fractions and outputs their weight signal. A microprocessor 200 receives the weight signal of each tobocoo fraction and calculates wt.% of each tobocco fraction to the total weight as a scale indicating the degree of deterioration.

Title: Transmission line fault section decision processing system
Inventor: OISHI YUICHI
IPC: H04L12/24
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To specify a fault section in a short period and to relieve the fault of a transmission line by deciding a path constitution from an alarm signal, comparing the alarm with the alarm of the other opposed multiplex converter on the path constitution and specifying the fault section, not by the manual decision of the fault section. SOLUTION: A multiplex converter(MUX) classification decision part 61 discriminates whether an inputted alarm signal is transmitted from the MUX which is possible to decide a fault section or not. A path registration decision part 62 decides whether a portion is registered as a path constitution or not from the individual information on the MUX included in the received alarm signals and the contact information, in the case of the alarm signal is possible to decide a fault section. When the portion where the alarm signal is generated is registered as the path constitution, a fault section decision part 64 refers to a path information storage part 65 and specifies the fault section. Therefore, because a fault generation section can be specified in short time, a fault generation portion can be early restored.

Abstract: PROBLEM TO BE SOLVED: To easily detect and correct the inclinations of an optical disk and a laser light optical axis by performing electric processing without changing a conventional device structure in an optical disk device using a semiconductor laser element having a main electrode and a plurality of sub-electrodes as a light source. SOLUTION: By controlling the injection of a current to a semiconductor laser element 3 having a main electrode and a plurality of sub-electrodes, the wave surface of a generated laser light is modulated, the inclinations of an optical disk 9 and an objective lens 8 are detected based on the fluctuation of a signal output at this time, and by setting a current injected to the semiconductor laser element according to the detected inclinations, the inclinations are detected and corrected. Since the inclination detection and correction are carried out by electric modulation, no new part items need to be added for inclination detection, no limitation is placed on a control band by sub-resonance in a high frequency band like the case of a mechanical actuator, and high-speed control is carried out until a high frequency.

Title: Semiconductor photo-coupler
Inventor: KUWANO YUKINORI
IPC: H01L31/12
Filed: 1981-12-18
Abstract: PURPOSE:To output the signals of a predetermined level or higher from a light-receiving element, and to obtain AND output to input signals to two light-emitting sources by oppositely arranging the light-emitting sources radiating the light of wavelength regions at the long wavelength side from peak wavelength and the short wavelength side to the light-receiving element. CONSTITUTION:When input signals are fed to the first light-emitting source 6a, luminous wavelength lambdaa thereof is 700nm, the light-emitting source 6a emits light and light transmits a light transmitting insulating substrate 1 and a transparent electrode film 3 and irradiates the opposite light-receiving element 2, but light is absorbed by the N type layer of an amorphous silicon layer 4, and only output Pa at the low level of the predetermined value level Pth or lower is obtained. When input signals are fed to the second light-emitting source 6b, luminous wavelength lambdab thereof is 460nm, on the other hand, the source 6b emits light similarly and light irradiates the light-receiving element 2, reaches the amorphous silicon layer 4 and is absorbed by a P type layer, and output Pb is brought to a level lower than the predetermined level Pth. When both light-emitting sources 6a, 6b are light-emitted simultaneously, however, output acquired from the light-receiving element 2 is the AND of the input signals of the first and second light- emitting sources 6a, 6b because output Po at a level higher than the predetermined level Pth is obtained.

IPC: H01L21/205
Filed: 1985-09-19
Abstract: PURPOSE:To uniformize the thickness and quality of a thin film in a thin film forming apparatus which utilizes a flow discharge by raising the temperature of a substrate periphery from that of the center. CONSTITUTION:Glow discharge plasma of reaction gas is generated between a high frequency applying electrode 5 and a substrate mounting electrode 6, the gas is decomposed in the plasma, and accumulated on a substrate 7. In this case, the temperature of the periphery of the substrate 7 is set higher than that of the center to accelerate the surface reaction of the periphery and to simultaneously uniformize the quality of the film.
