Patent JP-H08292127-A (JP)
Title: Method and apparatus for inspecting color filter
Inventor: SONEHARA AKIO
IPC: G01M11/00
Filed: 1995-04-24
Abstract: PURPOSE: To make it possible to process the smooth inspection by converting the signal outside of an tolerance range among the detected signals of the respective colored picture elements of red (R), green (G) and blue (B), into the constant numerical value. CONSTITUTION: A color filter substrate is conveyed into a loader part A through a carrier port 1. The inputted substrate is carried to the inspection stage of an inspecting part from the loader part A by a moving part. The substrate, whose inspection is finished, is moved to an unloader part by the moving part. Then, the substrate is conveyed out through an outputting port 2. In the inspecting part, the substrate mounted on the inspection stage is illuminated with a light source. The light from the color filter is detected. The detected signal undergoes electric image processing in an image processing part. In this image processing, the detected signal outside a tolerance range among the detected signals of the respective colored picture elements of R, G and B is converted into the constant numerical value.  Thus, whether a defective part is present or not is judged based on the magnitude of the counted number of the picture elements outside the tolerance range. Therefore, the image memory to be stored as a reference is not required.

Title: Gallium nitride compound semiconductor light emitting device
Inventor: NAKAMURA SHUJI
IPC: H01L27/12
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a gallium nitride compound semiconductor light emitting device in which a gallium nitride compound semiconductor layer doped with p-type impurities is turned to a low-resistivity p-type. SOLUTION: A gallium nitride compound semiconductor light emitting device is formed by growing an n-type gallium nitride compound semiconductor layer and a gallium nitride compound semiconductor layer containing p-type impurities on a substrate by vapor deposition. The grown n-type gallium nitride compound semiconductor layer and the p-type gallium nitride compound semiconductor layer are annealed as a whole and the gallium nitride compound semiconductor layer containing p-type impurities turned to a p-type gallium nitride compound semiconductor layer. If the annealing time is set to 10min., the resistivity of the GaN layer doped with Mg as p-type impurity starts decreasing suddenly at a temperature exceeding 400 deg.C and a constantly low resistivity as p-type characteristics is exhibited at 700 deg.C and higher, which is an effect of the annealing.

Title: Servomotor driver
Inventor: NAKAMURA TADAHIKO
IPC: H02P7/29
Filed: 1978-08-15
Abstract: PURPOSE: To reduce the power loss of a servo-circuit, by detecting the rotational frequency of a motor driven by the output voltage of a DC-DC converter, feedbacking the detection signal to the servo-circuit and controlling the output voltage of the converter by an error signal of the servo-circuit.  
     CONSTITUTION: The voltage of a battery 1 is changed into an AC voltage depending on a control signal S1 applied to the control input terminal 11 of a transistor 8. The AC voltage is supplied to a rectifier 9 through a transformer 7. The output voltage of the rectifier is smoothed by a capacitor 10. A DC voltage S3 is thus applied to the motor 3. The rotational frequency n of the motor 3 is detected by a detector 6 and feedback to the servo-circuit 4. The error signal S2 is supplied from the servo-circuit 4 to a voltage-frequency converter 5 so that a pulse of duty factor corresponding to the error signal S2 is applied to the input terminal 11 of the transistor 8. The output voltage of the DC-DC converter 2 is thus controlled. Since the motor 3 is driven without using a motor driving stage, the power loss is reduced.

Title: Preparation of metal oxide semiconductor
Inventor: SATOU SATOHIKO
IPC: H01L21/316
Filed: 1980-07-21
Abstract: PURPOSE:To increase specific permittivity and make an IC compact by a method wherein a thin film of non-fusible metal such as Ta, Hf and Zr is allowed to stick onto a dioxide film on a semiconductor substrate and then the substrate is heated to convert these films into a thin oxide film containing a semiconductor component and a metal component. CONSTITUTION:A thin tantalum film 34 which is 50-200Angstrom  thick is attached by means of D.C. double-pole spattering onto a dioxide Si thin film 33 formed on a P type Si substrate 31 containing dioxide Si 32. Since a tantalum atom that is provided with kinetic energy can penetrate the dioxide Si thin films 32, 33 located as deep as 100Angstrom , the region of the thin film 33 becomes that of a mixture of dioxide Si and tantalum. This region is formed in the specified shape, before being treated with heat. Then the thin films 34, 33 are converted into an oxide 33' which is a mixture of tantalum and Si 500Angstrom  thick. By so doing, this makes it possible to readily obtain a compact MOSFET transistor having a metal oxide thin film with a larger specific dielectric constant.

Title: Oil-impregnated sintered bearing and manufacture thereof
Inventor: KANEZAKI NOBORU
IPC: F16C33/14
Filed: 1991-04-04
Abstract: PURPOSE:To provide such an oil-impregnated sintered bearing as excellent in a frictional characteristic and its manufacture in addition. CONSTITUTION:In an oil-impregnated bearing provided with a bearing hole 12, where a turning shaft 11 is inserted thereinto, in a bearing body 10 formed by a porous sintered alloy, it is made up of crushing a hole in a sliding surface 13 along an axial direction, where the turning shaft 11 is sliding, out of an inner circumferential surface of the bearing hole 12. In addition, at time of compressed powder forming, this oil-retaining bearing is manufactured by sintering this compressed powder after crushing the hole of a part coming into contact with a roughing part 19 by way of forming a through hole, serving as the bearing hole 12, through a rod 17 formed with this roughing part 19. Since the hole of the sliding surface 13 is crushed, lubricating oil on the sliding surface is in no case leaked out, thus a firm oil film with no oil-pressure drop is formed on the sliding surface, through which any local contact between the turning shaft 11 and the sliding surface 13 is prevented from occurring, thereby making a frictional factor in the bearing reducible.

Title: Ink type wire dot printer
Inventor: IKEDA YOSHITO
IPC: B41J2/255
Filed: 1982-06-10
Abstract: PURPOSE:To obtain high-quality prints with constant printing densities regardless of the variations of ambient temperature by using a system in which a heater for heating ink is provided near the end of wires in such a way as to keep the viscosity of ink at optimum value for printing. CONSTITUTION:Ink supplied by a pump 13 is supplied from the supply pipe 7a of an ink supply or discharge guide 7 to a head 1 and flows across a wire 30 in an ink pathway 36. Excessive ink adhered to the tip of wire is recovered from the discharge pipe, and at the same time the heater 1 is electrically energized to heat ink trapped in and around the wire 30 surrounded by a heat transmission plate 31. When the ink thus heated reaches a set temperature, printing is started. During the printing period, the heater 10 is kept under a temperature control so that the temperature of ink at the top of the wire is kept constant. Thus, even when hardly vaporizable high-viscous ink is used, the viscosity of ink is lowered to a desired one and kept constant, and therefore, the printing density can be stabilized and printing quality can thus be raised.
