Title: Hydrogen pressure regulator of hydrogen-cooled rotary electric machine
Inventor: KUMAGAI MIKIO
IPC: H02K9/24
Filed: 1985-03-30
Abstract: PURPOSE:To effectively utilize energy by regulating hydrogen gas pressure in a rotary electric machine in response to a variation in a load, thereby eliminating the consumption of the hydrogen gas. CONSTITUTION:A case 5 for containing a cooler 6, a heater 7 and filled with powder hydrogen storage alloy around the cooler and the heater is provided out of a hydrogen-cooled rotary electric machine. The case 5 is so connected as to flow hydrogen gas in a hydrogen gas circulating system in a rotary electric machine 1 via a pipe 4 to forcibly raise or lower the temperature of the alloy by the cooler 6 and the heater 7, thereby arbitrarily regulating the hydrogen pressure in the machine. Thus, the temperature change width in the machine is reduced and regulated, when the rotary electric machine load is varied, to redue a time lag in the hydrogen gas pressure in the machine in response to the load at this time, thereby improving the efficiency of the machine.

Title: Card storage case for automobile
Inventor: ISHIKAWA ERI
IPC: B42D15/10
Filed: 1991-03-29
Abstract: PURPOSE:To prevent increase in an installation space and pick up a desired card easily by identifying multiple stored cards. CONSTITUTION:In a card storage case which has formed an outer case 25 which can move between a storing position where cards are stored in a housing 4 and a pulling out position where the cards are pulled into a cabin, there are provided multiple card cases 31-33 which are rotatably-disposed in multiple layers in the outer case 25, and a position determining part 38 which expands a clearance on the top edge of the respective card cases 31-33, by interlocing with a movement toward the pulling position of the outer case 25. According to the movement to the pulling out position of the outer case 25, a clearance on the top edge side of the respective card cases 31-33 is expanded. It is thus possible to recognize and pick up a card C stored in each of card cases 31-33 easily and to contribute to space saving because the respective card cases 31-33 are overlapped with each other in the storing position.

Title: Control device for engine idling speed
Inventor: SHIICHI HIROYASU
IPC: F02D45/00
Filed: 1989-03-17
Abstract: PURPOSE:To enable the high degree of precise control of an engine speed increase by detecting the power generation mode of a generator, correcting an intake amount depending upon the detected power generation mode and correcting ignition timing for the predetermined time depending upon an increase or decrease in the power generation amount of the generator. CONSTITUTION:When an engine switch 3 is closed and an engine starts, a generator 1 starts to generate power and a battery 4 is charged with generated voltage. The voltage of the battery 4 is detected with a voltage detecting circuit 21. In addition, when the voltage drops to or below the predetermined value, a semiconductor switching element 22 becomes electrically live and exciting current is thereby fed to a field coil 11. Then, the output voltage of the generator 1 rises and the battery 4 is charged. In this case, a control unit 5 searches intake air correction amount from the predetermined table, depending upon generator output current, and the correction amount so obtained is used to correct a basic control amount for controlling an intake amount. Also, when a generated power amount increases (decreases), ignition timing is set to an advance (delay) side.

Title: High withstanding-voltage mos transistor
Inventor: WAKAUMI HIROO
IPC: H01L29/78
Filed: 1986-03-25
Abstract: PURPOSE:To obtain high withstanding voltage even when the film thickness of an epitaxial layer is thinned by equivalently forming a low-concentration impurity layer having the same conduction type as a substrate just under a drain region and a drift layer. CONSTITUTION:A P<-> type epitaxial layer 13 is shaped onto a P<+> type substrate 11, and a source region 14, a drain region 15 and a drift layer 16 are formed to the epitaxial layer 13. A P<-> type impurity layer 12 is shaped between the epitaxial layer 13 just under the drain region 15 and the drift layer 16 and the substrate 11. Impurity concentration in the vicinity of the surface of the impurity layer 12 is set so that it is brought to the same extent as the P<-> type epitaxial layer 13 and made slightly lower than impurity concentration in the P<+> type substrate 11. Accordingly, the actual thickness of the substrate can be brought to the sum of the film thickness of the P<-> type epitaxial layer 13 and the film thickness of the P<-> type impurity 12, thus acquiring withstanding voltage largely higher than conventional devices even in the film thickness of the same epitaxial layer 13.

Filed: 1990-03-16
Abstract: PURPOSE:To uniformize a lubricant distribution and to prevent the remaining of dust, etc., by applying a lubricant on a medium, then wiping the surface of the medium with a prescribed woven fabric. CONSTITUTION:After the lubricant is applied on the magnetic disk medium 1 constituted by forming a magnetic film on the surface of a nonmagnetic substrate, the surface of the medium 1 is wiped by using the woven fabric 5 consisting of synthetic fibers of <=0.3d (denier) size. The wiping is executed by pressing the woven fabric 5 to the rotating medium 1 or moving the woven fabric 5 while pressing the woven fabric 5 to the surface of the fixed medium 1. Consequently, the woven fabric 5 eventually entangles and captures dust among the fibers. The power to remove the dust is thus enhanced.

Title: Optical disk drive device
Inventor: KANEKO HIROSHI
IPC: G05B11/36
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To make accurately and automatically adjustable a focus gain when reproducing an optical disk. SOLUTION: In the optical disk drive device, a preamplifier 22 is provided between an A/D converter 6 and an adder 8, and a phase comparator 12 linearly compensates for a loop gain that is controlled by a gain-variable amplifier 10 when a phase error signal to be outputted deviates from a range where a linear relationship is established for an amplitude error signal. A phase error data that is retained by a phase error retention register 23 is compared with a nonlinear range that is retained by a nonlinear range retention register 24. Then, when a phase error is included in the nonlinear range, gain compensation is instructed to increase the compensation gain as the phase error signal deviates from the linear range, thus being capable of improving focus control performance and reproduction performance in general.

Title: Trouble diagnoser for engine controller
Inventor: YAMAGUCHI MASAAKI
IPC: F02D41/22
Filed: 1988-03-24
Abstract: PURPOSE:To make a trouble diagnostic area enlargeable by continuing a trouble diagnosis as long as the preset time even if a detection signal, detecting an engine running state, comes off the trouble diagnostic area. CONSTITUTION:A trouble diagnoser for an engine controller performs a trouble diagnosis when a detection signal out of a detecting means 100, detecting an engine running state, is within a trouble diagnostic area. In this case, even if the detection signal is so judged that it is dislocated from the trouble diagnostic area by a judging means 101 which judges on whether this detection signal is within the trouble diagnostic area or not, the trouble diagnosis is continued as long as the specified time since it has been dislocated, by a trouble diagnostic controlling means 102. For example, when intake pipe suction pressure is varied and dislocated from the trouble diagnostic area in a short time, the trouble diagnosis has been suspended even if it is in a trouble diagnosable state in the past, but according to this method, a trouble judging opportunity is thus enlarged owing to continuation as long as the specified time by the trouble diagnosis controlling means 102. Thus, the trouble diagnostic area is enlargeable.
