Patent JP-H08322291-A (JP)
Title: Inverter
Inventor: FUJITA HIROSHI
IPC: H02P27/08
Filed: 1995-05-25
Abstract: PURPOSE: To suppress the switching loss of the power switching device of a phase corresponding to a coil which carries an overcurrent by a method wherein the stator coil connections of a multiphase AC motor are effectively utilized to restrict at least currents flowing through coils which carries no overcurrents. CONSTITUTION: When the U-phase current of a three-phase induction motor is excessively increased, the detected U-phase current exceeds a predetermined threshold TH and the level of the comparison signal of a comparator 31 is turned to H. Therefore, AND gates 37c-37f cut off PWM signals of a V-phase and a W-phase in accordance with the cutoff command of a gate cutoff command circuit which is based upon a truth table. As a result, the respective current flows into the respective stator coils of the V-phase and the W-phase are discontinued by the discontinuation of the switching operations of the respective corresponding power switching devices. Therefore, the overcurrent flowing through the U-phase stator coil can be adjusted and reduced so as to make the vector sum of the currents flowing through the respective stator coils zero.

Inventor: TAKAHASHI KAZUHIRO
IPC: G06F17/50
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To surely optimize the cell layout with the least total wiring length by minimizing the number of signal lines crossing one line segment after imaginarily laying the signal lines and placing cells on regions divided by the one line segment, without increasing the total area of the cells. SOLUTION: An available region 5 is divided by cut lines 5a-5f into 16 new regions. Placing cells 2a-2b on any of the new regions formed by this division is repeated so as to minimize the number of signal lines crossing the cut lines 5a-5f areas and not to increase the total area of cells to be set on new regions formed by dividing along selected line segments, relative to that of the new regions. Thus the cells 2a-2b are placed on the regions 6a-6d and connected by the same signal line 3 and hence an optimized cell layout with the least actual total wiring length is obtained.

Title: Quantum interference effect transistor and manufacture thereof
Inventor: ARIMOTO HIROSHI
IPC: H01L29/201
Filed: 1989-05-19
Abstract: PURPOSE:To improve a transistor of this design in interference effect by a method wherein electron waves passing through a second and a third slit are controlled in phase difference by controlling the electric field of the second or the third slit to control a current which flows from a source layer to a drain layer. CONSTITUTION:A transistor of this design is composed of a source layer 4, a drain layer 18, and a first channel layer 8 and a second channel layer 12 sandwiched between the layers 4 and 18 which are all laminated together, and a drain current flows vertically to the surfaces of these layers, so that the distance between the source layer 4 and the drain layer 18 can be easily made short. Therefore, electrons passing through the channel layers 8 and 12 can be reduced in chance that they encounter elastic scattering. Electron waves passing through a second and third slit, 22 and 24, provided to a second barrier layer 10 between the channel layers 8 and 12 are controlled in phase difference by a gate electrode which controls the electric fields of the second and the third slit, 22 and 24, whereby the electron waves passing through the second and the third slit, 22 and 24, can be made to interfere enough with each other. By this setup, the interference effect concerned can be enhanced.

Title: Minute displacement element
Inventor: WAKAMIYA MASAYUKI
IPC: H01L41/08
Filed: 1985-06-12
Abstract: PURPOSE:To make the strength of a minute displacement element large and to make the amount of displacement large, by fixing piezoelectric elements to a metal plate comprising amorphous alloy, and supporting and fixing a part of the metal plate. CONSTITUTION:Piezoelectric elements 2, which are polarized in the same thickness directions, are stuck and fixed to an amorphous alloy ring 1 in the concentric state with a bonding agent such as epoxy resin. Thus a piezoelectric vibrator is formed. An optical lens 3, which is mounted on an amorphous alloy plate, is fixed and supported at the central part of the piezoelectric vibrator. The outer surface of the amorphous alloy plate 1 of the vibrator, which is protruded from the outer surface of the piezoelectric element 2, is fixed and supported by an outer frame 4 such as a metallic frame. Silver electrodes 5 are formed on the upper and lower surfaces of the annular piezoelectric elements 2 of the optical-lens fine-moving device formed in this way. When a voltage is applied, one piezoelectric element is elongated to the radial direction, and the other is contracted. Thus the piezoelectric vibrator is deflected, and the lens 3 at the central part undergoes minute displacement in the direction of the optical axis. When a voltage in the reverse direction is applied to the piezoelectric element 2, the lens 3 is displaced in the reverse direction.

Title: Magnetic head and its production
Inventor: KOBAYASHI TAKAYUKI
IPC: G11B5/245
Filed: 1984-06-22
Abstract: PURPOSE:To form a gap having sufficient strength by making the sectional area of a groove for winding larger than that of a track width prescribing groove in a composite magnetic head where a nonmagnetic material is packed in the track width prescribing groove. CONSTITUTION:The sectional area of the C-shaped groove for winding is made larger than that of the V-shaped groove 6 for track width control so that a nonmagnetic material 9 packed in the track width prescribing groove 6 is prevented from flowing out to a winding window 7 by its capillary phenomenon and air bubbles do not remain in the last head because air bubbles remaining in the nonmagnetic material 9 are concentrated on the center part of the track width prescribing groove 6. The V-shaped groove is so worked that the length between the center position of the V-shaped groove and a part which an operating gap and prescribes the track width is 50-90% of the core thickness of the head. Thus, the nonmagnetic material is not flowed to the C-shaped groove for winding in the bonding process through the nonmagnetic material is packed in the V-shaped groove.

Title: Form cylinder for color changeover in rotary mimeographic press
Inventor: URURITSUHI MIYUURAA
IPC: B41L13/18
Filed: 1984-06-22
Abstract: PURPOSE:To control color density, by a construction wherein an air-feeding pipe is fitted into a hollow rotary shaft, a compression spring and a piston plate are fitted to a knob provided at an end of the pipe, and an air-discharging pipe communicated with the air-feeding pipe is provided. CONSTITUTION:When the knob 23 is rotated, the air-feeding pipe 22 is rotated, and a roller support plate 33 is straightened or bent to change the position of an ink-diffusing roller 32. When the outer peripheral surface of the roller 32 is strongly pressed against the inner peripheral surface of the form cylinder 1 at position A, the amount of an ink 4 exuding through minute holes 2 is increased, thereby increasing the color density in printing. When the contact of the roller 32 with the form cylinder 1 is released by bringing the roller 32 to position B, the amount of the ink is decreased, thereby decreasing the color density. A piston 25 is pushed into the knob 23 against the compression spring 24, air is fed into the pipe 22, and is discharged into the form cylinder through the air-discharging pipe 31 and a pipe 30. The ink 4 contained in the form cylinder 1 is fed out to the exterior through the holes 2 by the pressure inside the cylinder 1. Accoringly, the internal pressure is increased as the number of times of pushing is increased, whereby the amount of the ink fed out is increased, and the color density is increased. When the piston is not pushed, the color density is lowered.

Filed: 1980-09-12
Abstract: PURPOSE: To simplify a power source device and contrive to prevent the generation of vibrations and noises due to high-frequency waves by a method wherein a hydraculic speed-change clutch for changing the rotation speed of an impeller in accordance with the magnitude of the hydraulic pressure supplied is interposed between the runner and a submerged motor.  
     CONSTITUTION: In the submerged motor pump 1, the hydraulic speed-change clutch 5 is interposed between the underwater pump 4 and the impeller (not shown) in the main body 3 of the pump 3 so as to change the rotation speed of the impeller. For example, when the discharge water pressure exceeds a preset pressure of feed water, pistons 22, 23 in a control valve 18 are moved to the right in the figure, so that a drain port 31 is communicated with a hydraulic pressure supplying port 29, reducing the hydraulic pressure PCL at the clutch. As a result, the amount of slipping of the hydraulic clutch 5 is increased, the rotation speed of the impeller is lowered and the discharge water pressure is reduced. Accordingly, the power source device can be simplified, as compared to the case of using a variable speed motor, and the generation of vibrations and noises due to high-frequency waves can be prevented.

Filed: 1990-05-17
Abstract: PURPOSE:To improve wear resistance by forming a layer consisting of the carbide, nitride, and carbonitride of an Hf-Zr alloy on the surface of a base material to a specific thickness. CONSTITUTION:A coating layer of 0.5-10mu layer thickness consisting of one or more kinds among the carbide, nitride, and carbonitride of an Hf-Zr alloy is formed on the surface of a base material consisting of a hard member. When a surface treated hard member having this hard coating layer is used as cutting tool or wear resistant tool to perform high speed machining, ZrO2 having extremely high hardness at high temp. is formed owing to temp. rise at the edge and, as a result, wear resistance is not deteriorated even at the time of high speed machining. However, since this hard coating layer is slightly inferior to the carbide, etc., of Hf or Ti in adhesive strength to the base material and oxidation resistance, the carbide, etc., of Hf or Ti are formed between the hard coating layer and the base material, by which the adhesive strength of the hard coating layer to the base material can be improved.
