Title: Linear motor and linear motor-driven elevator
Inventor: NIHEI HIDEKI
IPC: H02K41/02
Filed: 1995-04-05
Abstract: PURPOSE: To prevent the vibration of a mover even when the gap lengths fluctuate on both sides of a double-sided linear motor. CONSTITUTION: In a double-sided linear motor which has two thrust generating gaps G1 and G2 on two surfaces and is set to the position at which generated attraction forces offset each other, first and second gap maintaining mechanisms 4 and 5 which respectively maintain gap lengths A and B on the two surfaces are provided and an expanding/contracting mechanism 53 is only installed to the second mechanism 5 which sets the gap length B longer than the other B. Since the attraction force on one secondary side 2 always becomes stronger than that on the other secondary side and the primary side 1 is run while the side 1 is pressed against one secondary side, the primary side 1 can be run stably without receiving any influence from the attraction force on the other secondary side.  Since the primary side 1 does not vibrate much, in addition, a linear motor having high durability and producing less noise can be obtained.

Abstract: PURPOSE:To improve combustion by providing a plural number of shallow subcylinders to a device in which a subpiston is fitted to the subcylinder communicated to a combustion chamber and slidably controlled by supplying pressure oil to a back side of said subpiston. CONSTITUTION:A subpiston 13 is fitted to a plurality of subcylinders 11 communicated to a combustion chamber 5, and pressure oil is supplied through a check valve 18 to a hydraulic chamber 17 located to a back side of the subpiston, while a spill unit 22 changing a discharge amount of working oil from a spill port 21 is driven by a driving gear 25, and a position of the subpiston 13, that is, compression ratio is controlled. Since enlargement of total sectional area by providing said plural subcylinders 11 can decrease a depth of the subcylinder 11, the subcylinder 11 is well scavenged at a retracted position of the subpiston 13, and a distance of flame propagation is decreased, then combustion is improved and cooling of the subpiston 13 can be improved.

Abstract: PURPOSE:To enable a device to serve multiple purposes as a driver, a telephone IC, or the like by a method wherein an oxide film is provided along the boundary between a first and second semiconductor substrates corresponding to dielectric-isolation structural elements for the integration into one chip of the dielectric-isolation structural elements and a vertical MOS. CONSTITUTION:On a laminate consisting of a first semiconductor substrate 1 and second semiconductor substrate 3 of the same conductivity type bonded to each other, a dielectric-isolation structural elements region 15 and vertical MOS region 16 are provided. An oxide film layer 2 is provided along the boundary between the substrate 1 and substrate 3 in a region 15. Along the boundary between the substrate 1 and substrate 3 in a region 16, there is no room for an oxide film, the two being bonded into one. In the region 15 there is an oxide film layer 2 and therefore there is no latchup because elements are independent from each other. In the region 16 there is no oxide film and therefore a large current is allowed through the region 16. A device designed as such may be used for multiple purposes, for example, as a driver, telephone IC, and so forth.

Title: Switching valve
Inventor: HIROSE KENJI
IPC: F16K31/06
Filed: 1986-04-08
Abstract: PURPOSE:To reduce the consumption of electric power, by connecting a transistor to an intermediate tap, in series with the primary coil and in parallel with the secondary coil, under using output of an electric discharge circuit and an integration circuit as input. CONSTITUTION:In the beginning of energizing of an electromagnetic coil 38, as voltage of an integration circuit 39b is low, a transistor 39c is in on-state, therefore only the primary coil 38e is energized for attracting a plunger, through streaming big current to draw out a big attraction. When voltage of the integration circuit 39b rises for turning off the transistor 39c, after attracting the plunger, the circuit is changed to an electric circuit formed of the primary coil 38e and the secondary coil 38f, and the streamed current is restricted so as to be proportionate to the holding torque. If the power source is cut off momentarily by such as momentary power failure, the plunger can be attracted certainly after the power source is restored, by function of an electric discharge circuit.

Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus in which the vacuum leak and the electric- circuit defect of a strain gate-type pressure sensor used for a vacuum sensor can be estimated safely, without any pollution and nearly simultaneously without using radioactivity. SOLUTION: In a state that a prescribed vacuum pressure is applied to the pressure introduction pipe 3 of a pressure sensor 1, a bias voltage at 6V DC is applied across electrodes 2, and an output voltage is measured. When an output value is at 1V or lower, the pressure sensor is judged to be a good product. When the output value is zero or exceeds 1V, the pressure sensor is judged to be a defective product. Then, an applied vacuum pressure is brought gradually to atmospheric pressure. When the output voltage value is raised suddenly during a halfway part, the pressure sensor is judged to be a product. When the output voltage value is not changed, the pressure sensor is judged to be a defective product. All the electrodes 2 are short-circuited, and a high voltage at 600V DC is applied across the electrodes and a metal case 6.  When an electric discharge is not generated, the pressure sensor is judged to be a product. When the electric discharge is generated, the pressure sensor is judged to be a defective product. In the pressure sensor in which the electric discharge is generated, a vacuum leak state is computed on the basis of the relationship between an electric-discharge voltage value and an electric-discharge current value. When the leak rate is at a prescribed value or lower, the pressure sensor is judged to be a product.

Abstract: PURPOSE:To suppress the current fluctuation of a constant current source and to obtain a stable constant current circuit, by applying a negative current feedback with use of a current proportional to the output current of the constant current circuit. CONSTITUTION:A single collector of a pnp transistor TRQF of a multi-collector is connected to the emitter of a TRQ2 and has the same base-emitter characteristics as those of the TRQ1, Q5 and Q6.

Thus the current of the collector connected to the emitter of the TRQ2 is defined as alphaIX among plural collectors (alpha: constant). Here the current IC flowing through a resistance R1 is equal to the sum of the collector current IX of the TRQ1 and the current alphaIX of the collector connected to the emitter of the TRQ2 among those collectors of the TRQF.

Abstract: PURPOSE:To prevent pseudo synchronization from being caused at a demodulating part. CONSTITUTION:At a transmitter, transmission information data 2 and the output 4 of a unique word generator 3 are multiplexed by a unique word multiplex circuit 5, and are sent to a transmission line. At a receiver, a sweep control part 25 stops the sweep of the demodulating part 14 when an FEC synchronization/asynchronization signal 24 is 'synchronization', and sets an internal timer. Then, the sweep control part 24 monitors the frame synchronization/asynchronization signal 24, and if the contents of the signal 24 become 'synchronization' before the internal timer times out, it resets the internal timer, and if the signal 24 does not become 'synchronization', and 'asynchronization' continues, and the timer times out, it cancels the stoppage of the sweep of the demodulating part 14, and starts the sweep so as to execute again frequency follow-up.
