Title: Test apparatus for hydraulic motor (or pump)
Inventor: NAGATOMO KUNIYASU
IPC: F04B51/00
Filed: 1979-05-09
Abstract: PURPOSE: To regenerate power, dispersed into the atmosphere due to the rise of oil temperature, by mechanically interlocking a sample hydraulic motor with a load hydraulic motor while interconnecting the discharge side and suction side of these motors with piping.  
     CONSTITUTION: In the test of a sample hydraulic motor 1, oil discharged from a hydraulic pump 4 driven by a motor 5 is supplied to a hydraulic motor 3 to rotate simultaneously the sample motor 1 and a load hydraulic motor 2 by an auxiliary transmission means 9. The motors 1, 2 are interconnected through a shaft coupling 8. Since the discharge sides and the suction sides of the motors 1, 2 are respectively interconnected by pipes 11, 12, oil discharged from the load hydraulic motor 2 enters the sample hydraulic motor 1, and oil discharged from the sample hydraulic motor 1 enters the load hydraulic motor 2. Thus, power is regenerated, leaving the hydraulic pressure as it is so that the test power can be substantially reduced.

Title: Liquid phase epitaxial growth method
Inventor: MATSUMOTO TADAO
IPC: H01L21/208
Filed: 1978-05-11
Abstract: PURPOSE: To establish the uniform and flat epitaxial layer with good contact between the substrate and molten liquid, by removing the oxide film on the substrate surface before epitaxial growing start at the specified temperature and under reducing atmosphere, and isolating it from the reducing atmosphere at high temperatures.  
     CONSTITUTION: The GaAs substrate 12 is placed on the groove of the slide 10, it is heated to 100 to 500°C in the furnace filling H 2  gas, and the oxide film on the substrate surface is removed with reducing. Further, the slider 10 is shifted, the substrate 12 is placed in the barrier of the vessel 8, and it is held at more than the growing start temperature of 500°C with heating. Thus, the Ga solution constituting the molten liquid 11 is sufficiently saturated with As, and no surface is damaged because the substrate is not in contact with high temperatures during this time. Further, the slider is shifted, the substrate is contacted with the molten liquid and it is immediately and gradually decreased from the growing start temperature to form the uniform and excellent epitaxial layer. The substrate is again moved in the vessel and the temperature is returned to room temperature, and the substrate is picked up in the atmosphere replaced into N 2  atmosphere. At the substrate temperature less than 100°C, the contactness is no good and the surface is coarse with the temperature more than 500°C.

Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/65
Filed: 1989-03-08
Abstract: PURPOSE:To obtain the magnetic recording medium which is improved in both durability and C/N by forming a perpendicularly magnetized film of a Co alloy on an undercoating layer which consists of any of Pd, Rh, Pt and is disposed on a granular base. CONSTITUTION:The undercoating layer 3 consisting of any of the Pd, Rh, Pt is disposed on the granular base 2 and the perpendicularly magnetized film 4 of the Co alloy is formed thereon. The Pd, Rh, Pt internally cause slip deformation in the granular projecting parts to be most strongly subjected to the stresses that the medium receives from a head, thereby preventing the destruction thereof. Since the surface is leveled off by the Pd, Rh, Pt, the crystallinity is more improved than with the medium formed by disposing the perpendicularly magnetized film 4 of the Co system directly on the granular base 2 and the characteristics are uniformized. The durability and C/N are improved in this way.

Title: Disc brake
Inventor: KOBAYASHI KINZO
IPC: F16D65/18
Filed: 1985-03-20
Abstract: PURPOSE:To prevent return phenomenon to be caused by external impact force by installing a one-way valve in the flow line leading from a master cylinder to a liquid pressure chamber so as to allow only inflow of the oil into the liquid pressure chamber, and by equipping this one-way valve with a throttle passage. CONSTITUTION:When a snow lump or the like runs against callipers 3 to push them the whole in the A direction with shocks, a piston 5 contacts a disc 1 with a friction pad 12 interposed, to restrict movement in the A direction. As a result, the piston 5 receives such an impact load as to be intruded in a cylinder 4 at a comparatively high speed. At this time, however, the oil in a liquid pressure chamber 6 receives a large resistance when passing through a throttle passage 29, and the amount Q of oil exhausted out of the liquid pressure chamber 6 can be restricted greatly. Accordingly, so-called piston return phenomena are prevented.

While in a start circuit 4, because the resonance frequency of an inductor L2 and a capacitor C4 is set to the vicinity of the output high frequency of the circuit 2, terminal voltage of the capacitor C4 is increased at the time of a no-load start. This voltage is rectified by a DB2, and when the voltage of a capacitor C5 charged via a resistor 5 reaches a prescribed value, discharge is performed at a gap G to emit a charge. By this emission, a discharge lamp 3 to which boosted pulse voltage is applied by a pulse transformer PT is started to perform arc discharge by the repetition of discharge to light the discharge lamp 3. This can improve start performance.

Filed: 1995-02-23
Abstract: PURPOSE: To start a switch type reluctance motor accurately without requiring an absolute rotary encoder by performing open loop control up to a reference position of the rotor and then performing closed loop control. CONSTITUTION: Electrical angle of a rotor 2 is divided equally by 16 to form electrical ranges 1-16.

After a specific position representative of the reference position is detected by detection means 21, electrical angle 15 determined based on the reference position and an increment signal before closed loop excitation control is started. With such arrangement, accurate starting can be realized without requiring an absolute rotary encoder.

Abstract: PROBLEM TO BE SOLVED: To make it possible to set the temperature of a semiconductor wafer to a specified value by setting the frequency at which multiple semiconductor integrated circuits formed on each wafer operate, based on the yield of each semiconductor wafer. SOLUTION: On the main side of a semiconductor wafer 1, multiple semiconductor integrated circuits are formed in rows and columns. For example, a burn-in test is made on elements C1 through Cn, which are judged as non- defectives. At this time, suppose that the heating value proportionally increases as the operating frequency becomes higher. Under the condition, an equation Q=f×α can be obtained, where (q) is the heating value per circuit element, (f) is the operating frequency, and α is the proportional constant. Also, an equation Q=n×q=N×f×α can be obtained, where Q is the heating value of the semiconductor wafer 1, and (n) is the number of non-defectives. Further, an equation Q=N×P×f×α can be obtained, where N is the number of circuit elements produced from the semiconductor wafer 1, and P is the yield.  When (f) is set so that the product of P by (f) becomes a specified value, Q can be set to a specified value.

Title: Production of magnetic head
Inventor: YODA HIROSHI
IPC: G11B5/265
Filed: 1989-03-10
Abstract: PURPOSE:To drastically decrease the fluctuation in a gap depth by forming at least the gap depth-regulating parts of winding windows after working of head sliding surfaces. CONSTITUTION:The sliding surfaces are polished by using a lapping tape so as to attain prescribed front end radii. The winding windows 5 are formed in the positions apart by the gap depth D from the sliding surfaces of the respective head chips 1 of the magnetic head 4, which is finished to the sliding surface shape. Ultrasonic machining using fine abrasive grains and machining using laser light are possible for forming the window. The wiring window 5 of the respective head chips 1 are opened to the places apart by the prescribed positions from the head sliding surfaces after the head chips 1 are stuck to a head base 2 and the head sliding surfaces are polished; therefore, the gap depth can be regulated without having the sticking errors of the chips 1 to the head base 2 and without having the influence of the fluctuations in the radius shape at the time of the polishing of the front surface. The head having the uniform head gap depth value is thus obtd. even when the many chips 1 are mounted on one head base 2.
