Title: Crystal growth for gallium nitride thick film
Inventor: KIMURA AKITAKA
IPC: H01L21/205
Filed: 1997-09-02
Abstract: PROBLEM TO BE SOLVED: To provide a method of crystal growth comprising crystal growth of a gallium nitride film by the use of quartz with Z-cut plane as the surface as substrate followed by easily removing the substrate to form the aimed hard- to-crack gallium nitride thick film. SOLUTION: This method of the crystal growth for a gallium nitride thick film is comprised of the following process: using quartz with Z-cut plane as the surface as substrate, a gallium nitride film is subjected to crystal growth pref. by halide vapor growth technique followed by removing the substrate. Because of using the above quartz substrate, the crystallinity of the resulting gallium nitride thick film is improved compared to the case with using a quartz substrate with another crystal plane as the surface. The surface of the quartz substrate to be used need not be exact Z-cut plane, a plane with an angle made with the Z-cut plane within 10 deg. being enough. The quartz substrate can be easily removed by etching or grinding.  Using the resultant gallium nitride thick film as substrate, a semiconductor laser structure consisting of a nitride-based compound semiconductor layer with its cleavage plane coinciding with that of the above thick film can be formed.

IPC: B41J27/10
Filed: 1986-10-06
Abstract: PURPOSE:To transfer yet-dried paint onto the surface of a paper sheet at all times, by arranging a paper sheet sensor at a position separated by a distance longer than the circumferential length in the rotary direction between a position where rollers contact with a coating means to a contacting position of rollers, and turning a driving means on when said sensor detects a paper sheet being fed. CONSTITUTION:When the operation is started, a paper sheet to be processed is fed by means of a paper feed roller 3. When the leading edge of said paper sheet is detected by means of a paper sheet sensor 14, a motor is driven to start driving of rollers 4, 5. When said rollers 4, 5 rotate, yet-dried paint is applied through felts 6, 7 onto the surface of the rollers. After the yet-dried paint reaches the contacting position (passing position of paper sheet) of upper and lower rollers 4, 5, the paper sheet reaches said contacting position. Consequently, the surface of the paper sheet is applied entirely with paint. When such process is employed, quick drying paint can be used. If quick drying paint is used, it has been dried before the paper sheets are stacked, thus facilitating the stacking.

Title: Gas laser
Inventor: YUKIMURA KEN
IPC: H01S3/097
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To prolong the service life by consuming the residual charges in a peaking capacitor surely through a resistor through action of a magnetic switch being controlled to low inductance at the end of laser oscillation thereby eliminating the current flowing through a main discharge electrode upon finishing the laser oscillation and suppressing the consumption of main discharge electrode. SOLUTION: A magnetic switch 17 in a charge consumption circuit is normally controlled to high inductance by a current flowing through a reset winding 18 for bringing the core into magnetically unsaturated state. Upon finishing the laser oscillation, the magnetic switch 17 is controlled to low inductance by a current flowing through the reset winding 18 for bringing the core into magnetically saturated state. Since the magnetic switch 17 is controlled to low inductance, residual charges in a peaking capacitor are discharged and consumed by a resistor 19 upon finishing the laser oscillation. Consequently, the current flowing through a main discharge electrode 15 is commutated to the charge consumption circuit upon finishing the laser oscillation.

Title: Method for impregnation
Inventor: MATSUO HIDEYASU
IPC: C01B31/02
Filed: 1987-09-25
Abstract: PURPOSE:To efficiently obtain a material to be treated having a high density, by placing the material to be treated and an impregnating substance in a metallic capsule and applying an impregnating pressure through a hot pressure medium to the impregnating substance. CONSTITUTION:A material to be treated is impregnated with an impregnating substance. In the process, the material to be treated and impregnating substance are placed in a metallic capsule and an impregnating pressure is applied through a hot pressure medium to the impregnating substance. Furthermore, heating is required in impregnation. Reasons therefor are as follows. If the impregnating substance contains carbon, the impregnating substance is carbonized. If the impregnating substance is a metal, permeation is facilitated by dissolving the metal. The heating temperature at this time may be freely set depending on the impregnating substance. Typical examples of the impregnating substance include a compact of carbonaceous material and tar pitch. The impregnating substance can be readily impregnated into the material to be treated by a hot hydrostatic pressing method and the aimed material of a high density to be treated is obtained.

IPC: G01N27/12
Filed: 1989-09-14
Abstract: PURPOSE:To accurately check the degree of the reaction of a combustion reaction gas by varying the output of the catalyst of the gas sensitive layer covering one electrode pair from the capacity of the catalyst of the gas sensitive layer covering the other electrode pair. CONSTITUTION:For example, two pairs of the electrodes are coated respectively with the gas sensitive layers KG1, KG2 and the capacities of the catalysts between the two gas sensitive layers KG1, KG2 are varied. A difference arises in the electric resistors R1, R2 of the two gas sensitive layers KG1, KG2 when the electrodes and the gas sensitive layers KG1, KG2 are exposed to a non-equil. gas which is a detecting gas. The change in the electric resistors R1, R2 is, thereupon, taken out as a change in an output voltage V0 and the degree of the chemical equil. of the detecting gas is known from the change in this output voltage V0. For example, a gas sensor is mounted on the down stream side of the catalyst converter of an internal combustion engine and is exposed to the exhaust gas discharged from the catalyst converter. The output V0 of the gas sensor at this time is measured, by which the purification rate of the catalyst converter is simply and easily known. The degree of the reaction of the combustion reaction gas is accurately checked in this way.

Title: Water heater
Inventor: ADACHI KAZUHIRO
IPC: F24H1/18
Filed: 1987-09-24
Abstract: PURPOSE:To reduce the cost of power consumption due to the continuous heater operation and prevent the thermal deterioration of a reducing valve by disposing a thermostat for controlling the heater temperature in a position on the inner surface of the outer casing at its middle height level where it is exposed to heat from the boiler body. CONSTITUTION:A thermostat 7 is exposed to heat from the boiler body 1, and its contact points are switched off to switch off a heater to while the combustion is under way for the water heater. At this time, the feed water pipe 5 will not be frozen because of the thermal convection and conduction in the boiler body 1. That is, although the heater 10 is switched on when the outdoor temperature is low, it is switched off when the combustion is underway in the water heater so that the time of activating the heater 10 during the winter season can be reduced so as to reduce the power consumption charge to the minimum. Further, since the reducing valve 4 is disposed between the feed water opening 3 and the heater 10 near the boiler feed water opening 2, it is not directly exposed to the heat from the heater 10 even if the outdoor temperature is 10-40 deg.C, preventing its thermal deterioration.
