Title: Electric compressor
Inventor: YOKOMACHI HISAYA
IPC: F04B17/04
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To unnecessitate a motion converting mechanism reciprocating a plunger and simplify a structure by fitting and inserting the plunger partitioning a compression chamber within a cylinder bore formed in a housing and disposing an electromagnetic coil reciprocating the plunger within the housing. SOLUTION: By repeatingly turning on/off energizing to an electromagnetic coil 6 disposed within a housing 1, a plunger 30 having a piston part 31 partitioning a compression chamber 3 within a cylinder bore 2 is reciprocated. When this plunger 30 is reciprocated, coolant within the compression chamber 3 is compressed by the piston part 31, and when pressure of coolant reaches a prescribed value or more, coolant is discharged from a discharge port 20 of a discharge path 21 toward an external coolant circuit, pushing a ball valve 25 open against a spring 26. When the electromagnetic coil 6 becomes a non- exciting state, the plunger 30 is reciprocated by a return spring 34. As a result, the inside of the compression chamber 3 becomes low pressure and coolant is sucked into the compression chamber 3 via a suction port 10.

Title: Method and device for driving electric motor for spindle of thread-plying machine
Inventor: MIZUUCHI SOTOO
IPC: D01H1/30
Filed: 1978-12-11
Abstract: PURPOSE:To eliminate the fluctuation of the rotation of an electric motor and improve the quality of a plied thread, by gradually raising a driving voltage for the motor from a prescribed level at prescribed frequency and then increasing the voltage while keeping its level proportional to its frequency. CONSTITUTION:At time t1, a thread-playing machine is started, switches S1, S3, S4 are closed and the output voltage of a variable DC voltage source 33 is amplified by the operational amplifier 37 of a gradient signal generator 200. The amplified voltage is integrated by an integration circuit comprising another operational amplifier 38 and a capacitor C2. The output voltage of the amplifier 38 rises at a speed set by a variable resistor 6. After the time t1, the outout voltage appears as a voltage control signal VS on a terminal 02. When another switch S2 is closed, the output of a variable DC power source 32 is applied to the operational amplifier 35 of another gradient signal generator 100 and processed in the same manner as in the former generator 200. At other time t2, a frequency control signal FS appears on another terminal 01. At still other time t3, the output of another operational amplifier 36 becomes constant and an electric motor is stably driven.

Title: Cmos semiconductor device
Inventor: TANIGUCHI TAKASHI
IPC: H01L27/08
Filed: 1989-06-15
Abstract: PURPOSE:To improve the resistance to latchup by arranging a first N-type diffusion layer on the side surface and the bottom surface of a trench formed in the N-well on a P-type Si substrate, and bringing the layer into contact with a second N-type diffusion layer formed on the N-well surface. CONSTITUTION:A trench is formed in an N-well of a P-type substrate 1, an N-layer 4 is diffused in the sidewall and the bottom of said trench, the layer is covered with an oxide film 5, said trench is filled with Si, and an N-layer 7 is diffused in the surface of the N-well, so as to be in contact with the N-layer 4. By applying a desired potential to the N-layer 7, the desired potential can be applied to the deep region of the N-well 2 via the N-layer 4 on the side surface and the bottom surface of the trench. As a result, the potential fluctuation of the well inside caused by a trigger current from the outside can be restricted within a sufficiently small range, so that the resistance to latchup can be improved.

Title: Spool
Inventor: TSUKAHARA YASUTO
IPC: B65H75/14
Filed: 1982-09-03
Abstract: PURPOSE:To aim at preventing the breaking of a wire, by forming a spool for an ultra-fine metal wire, in such a way that the cross-sectioned shape of the inside convex surface of one flange has a convex curve which is half of a parabolic curve, and a tapered barrel is used, thereby the pulling-up resistance of the wire is reduced and as well, the wire is prevented from thrusting into the flange surface upon winding the wire. CONSTITUTION:In the standing posture of a spool, the inside surface of the upper flange 2 of the spool has a convex curved surface part 7 in the substantial part of the inside surface, and the barrel is a tapered barrel 8 which is made thin upward. When a wire member is pulled up from the spool, the pulling-up resistance is abruptly reduced, and the wire is prevented from thrusting into the flange surface, which is liable to be occurred when the wire is wound onto a conventional spool. Further, due to the provision of the convex curved surface part 7, the winding pressure may be divided so that the flange may be prevented from being broken. Further, since the tapered barrel 8 has a large diameter lower section, it has a role to prevent the surface avalanche of the wire member in the surface 3 thickened by winding. 3. Further, since the convex surface part is formed in such a way that a half of a parobolic curve is rotated in one round about its axis, the wire member may be flatly wound if the traverse width is widened by a traverser moved at a constant speed. Thereby, the breaking of the wire and the damage of the flange may be prevented from being occurred.

Abstract: PURPOSE:To obtain a chemically stable record with high sensitivity by providing a recording layer on one or both sides of a base plate and forming a thin org. film consisting essentially of a specific naphthoquinone dye as a recording layer which records information by a laser beam. CONSTITUTION:This optical information recording medium which is provided with a recording layer on one or borh sides of a base plate and records and reads information by a laser beam is formed with the org. thin film consisting essentially of the naphthoquinone dye expressed by the chemical structural formula I as the recording layer. The sensitivity of the medium is increased preferably by matching approximately the absorption peaks of the recording wavelength and the recording layer and therefore a substituent is added to the naphthoquinone dye. The naphthoquinone dye is stable under the environmental conditions of relatively high temp. and high humidity and does not show the deterioration by oxidation in air unlike a Te alloy. Said compd. has low heat conductivity and the value thereof is 1/10-1/100 the value of metal. The diffusion of heat in the medium during laser light recording is thus decreased and the medium temp. in the light irradiated part is efficiently elevated.

Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To make the nipping width of a transfer nipping part small, while keeping high transfer efficiency by pressing a photoreceptor belt on an intermediate transfer body, in a state where the photoreceptor belt is linearly held, between a tension roller and a cleaning roller, through the use of a transfer roller. SOLUTION: The transfer roller 23 presses the photoreceptor belt 1 on an intermediate transfer body belt 19 from the rear surface of the belt 1, in the transfer nipping part in a position facing an intermediate transfer body belt supporting/carrying roller 20. In other words, the transfer roller 23 presses the photoreceptor belt 1 on the intermediate transfer body belt 19, in the state where the belt 1 is linearly kept, between the tension roller 3 and the cleaning roller 4. Therefore, even if the transfer nipping part, becomes small because the pressing force of the transfer roller 23 is directly exerted on the intermediate transfer body belt 19 through the belt 1, the belts 1 and 19 come into uniform contact with each other. Consequently, the flocculation of toner between the belts 1 and 19 can be prevented to eliminate a failure in transfer.
