Filed: 1988-02-26
Abstract: PURPOSE:To prevent any impurity from adhering to a substrate and a reactor inner surface by providing an ion source on part of a reactor to etch the substrate and clean the reactor inner surface. CONSTITUTION:An ion source 12 is provided on part of a reactor 1. A substrate 7 made of GaAs is etched by placing the substrate 7 on a susceptor 5 and putting the susceptor in the reactor 1, and further keeping the reactor l blocked from the atmosphere by closing a gate valve 4 and feeding etching gas activated in the ion source 12 into the reactor 1. A gate valve 14 disposed under the ion source 12 is opened to etch and clean a crystal of GaAs or AlGaAs adhering to the inner surface of the reactor 1 using an Ar ion and chlorine from the ion source 12. Hereby, any impurity is prevented from adhering to the substrate 7 and the reactor 1 inner surface.

Title: Seal mechanism for rotary hydraulic equipment
Inventor: OKATO YUKIO
IPC: F16J15/16
Filed: 1991-02-18
Abstract: PURPOSE:To avoid the sliding contact between the seal ring and the ring groove formed in the shaft and secure the formation of an oil film between these two, thus to prevent generation of excessively large wear, by forming an annular groove having a specified-width opening in the side face of the ring groove pressure contacted by the seal ring. CONSTITUTION:Seal ring 1 made of cast iron or the like are fitted into ring grooves 3 formed in a shaft 2 made of aluminium alloy or the like. The seal ring 1 is pressure contacted with a casing 5 by tension. Through action of an oil pressure from an oil passage 4, one-side side surface of the seal ring 1 is pressure contacted with the opposing side surface thereto of the ring groove 3 in the shaft 2. In this case, the side face of the ring groove 3 pressure contacted by the seal ring 1 is formed, over its full circumference, with an annular groove 8 rectangular in cross section and having an opening the width of which covers from one side of an inner circumferential corner angled portion of the seal ring 1 to the other side thereof, so as to prevent this corner angled portion from contacting with said side face. By this, sliding contact between the seal ring 1 and the ring groove 3 is not only avoided but the formation of an oil film is secured between these two.

Title: Damping device
Inventor: UNO MOTOO
IPC: G11B7/09
Filed: 1983-03-18
Abstract: PURPOSE:To obtain excellent damping effect over a wide range by inserting the feedback circuit of a sensing coil into a low-pass filter. CONSTITUTION:A driving coil arranged in a magnetic circuit 6 which is driven by a power amplifier 7 and made of a magnet 3 is wound with a sensing coil 5. Then, the output of the sensing coil 5 is fed back to the front stage of the power amplifier 7 through a compensating circuit 8. Consequently, phase rotation corresponding to mutual induction is canceled completely to obtain pure speed feedback equivalently, so the excellent damping effect is obtained.

Title: Electroscope
Inventor: ARAI SABURO
IPC: G01R19/155
Filed: 1997-01-23
Abstract: PROBLEM TO BE SOLVED: To enable detection of presence absence, kind, polarity and conduction of input electric power without changing over voltage by using a constant electric current circuit for a detecting section. SOLUTION: When voltage is applied to set a probe 1 to (+) and an earth ring to (-), electric current flows between the base and emitter of a TR 6 through a constant electric current circuit consisting of a FET 4 and resistance 5 and returns through a diode 8 to the earth ring 2. Then, a LED 7 (1/2 R) radiates light through a dry cell 12 by the conduction of the TR 6. When voltage is applied to a probe 1 and earth ring 2 so that both are set respectively to (-) and (+), a TF 11 is made conductive through a FET 9 and resistance 10 and returns to the probe 1 through a diode 3. The LED 7(1/2 G) radiates light through the conduction of the TF 11. Also, in the application of AC voltage, the LED 7 (1/2 R) and LED 7 (1/2 G) radiate light alternatively. When voltage is absent between the probe 1 and earth ring 2, the LED 7 does not emit light.  The presence absence, kind and polarity of the input electric power can be detected from the state of emission of light.

Title: Pretreatment for surface of metal for cation type electrodeposition painting
Inventor: MINO YASUTAKE
IPC: C23C22/82
Filed: 1981-03-26
Abstract: PURPOSE: To make the adhesive strength and corrosion resistance of the paint film after cation type electrodeposition painting much higher by using aq. mixed solns. of a Zr compd., myoinositol phosphate and its salts in post-treatment washing after phosphating.  
     CONSTITUTION: Metallic surfaces are phosphated with an aq. acidic phosphating soln. for cation type electrodeposition painting. Thence, it is treated with an aq. soln. contg. ≥0.05g/l (as ZrO 2 ) water-soluble Zr compd., ≥0.05g/l myoionositol phosphate (phytic acid) and or its water-soluble salts. Here, the aq. solns. of 3W 7pH obtd. at 1W50:1 molar ratios between the former and the latter are used. If the ratio of the former is below 1, the corrosion resistance is not enough, and in excess of 50, the stability of Zr in the liquid degrades. The selection of pH is also regulated by the concn. of the phytic acid, and the pH higher than that exhibited when a base of the amt. 4 times that of said acid in molar ratio is added is required. Below the 4 times amt., the stability of Zr in the liquid degrades. If the pH is below 3, phosphate films are eluted excessively and in excess of 7, there is no improvement in the corrosion resistance.

Filed: 1985-03-08
Abstract: PURPOSE:To attain smooth and fast shifts of a recording part and a part to be recorded with reduced frequencies of record and shift stops, by setting the actual shift speed of the (i+1)-th record unit at the value less than the record speed of the (i+1)-th record unit. CONSTITUTION:A control part 100 decides the paper feed speed which is equal to the shift speed of the next line showing the (i+1)-th record unit from the record speed of each line recorded on a record speed buffer 80. Then the part 100 gives a command to a record driver 90 to energize a heat-sensitive record head 110 and prints picture signals equivalent to a line to the record paper 140. A pulse motor 130 is driven according to the decided shift speed to perform the paper shift to shift relatively a part to be recorded for each record unit. In such a way of decision of the paper feed speed, the paper is shifted smoothly at a high speed with no sudden stop and with small line buffer capacity.

IPC: G01N15/02
Filed: 1979-04-12
Abstract: PURPOSE:To automatically and precisely measure the grain-size distribution of particles contained in a medium in one measurement without a preliminary measurement by detecting in order the number of the particles settling in the medium at a specified horizontal position every given time-interval. CONSTITUTION:An image at a detecting position h by a microscope 3 is converted into an image electric-signal S1 by a pickup tube 4, and a signal S2 of the particle number n is sent from a signal processing unit 5 to a memory and operation unit 6. The operation is continued at given time-intervals during sedimentation, and the obtained data are put in the block 6. The block 6 automatically calculates and memorizes the particle number, making the average particle-number of 250 for several seconds in the beginning of the sedimentation into a reference value, and the numbers of 10-90% of the value into nine distribution reference-values U10- U90. For example, the sedimentation time of 5.5 seconds corresponding to the particle number closest to U90=225 is calculated by the block 6 to obtain a particle diameter of 20mum, showing that particles smaller than 20mum exist 90%.

IPC: H01M8/06
Filed: 1988-02-25
Abstract: PURPOSE:To steadily supply main steam by varying the amount of excess steam in connection with the output power of a fuel cell. CONSTITUTION:The amount of excess steam corresponding to the output of a fuel cell 3 is calculated with a function generator 20, and the opening of a flow rate control valve 8a is automatically controlled so as to make excess steam to flow with a flow rate controller 19. The total steam amount Q0 generated from a steam separator 1 is constant and the sum of main steam amount Q1W and excess steam amount Q2W is the total steam amount generated, and the main steam amount is therefore fixed in connection with the output of the fuel cell 3. The excess steam amount is automatically fixed in connection with the output of the cell 3. If the excess steam amount is calculated and a control valve 8a is operated in connection with the output of the cell 3 to control the excess steam amount, the pressure variation within the steam separator 1 caused by excess or shortage of main steam extraction amount and excess steam extraction amount is eliminated.
