Title: Control method of motor for motor vehicle
Inventor: SUGIYAMA SHOJI
IPC: H02H7/093
Filed: 1992-02-07
Abstract: PURPOSE:To provide a controller for induction motor wherein the induction motor is protected against breakdown due to overrotation. CONSTITUTION:An induction motor 3 is driven through an inverter 2 which is fed with DC power from a battery 1. A driving circuit 8 drives the inverter 2. A slip frequency calculating circuit 4 sets a target torque to be produced from the motor 3 based on an acceleration signal and a brake signal while a sensor 5 detects actual rotational speed of the motor 3 and a slip frequency is determined based on the actual rotational speed and the target torque. A current command value calculating circuit 6 determines a primary current command value of the motor 3 based on the slip frequency fed from the slip frequency calculating circuit 4 and then controls the driving circuit 8 such that the command current will be equal to an actual primary current of the motor 3 detected through current detecting sensors 7a, 7b. When the actual rotational speed exceeds a preset rotational speed, slip frequency determined through the slip frequency calculating circuit 4 is modified to a value being set such that appropriate torque is produced in reverse direction from the induction motor.

Title: Synchronization circuit
Inventor: SAKAGAMI HIROFUMI
IPC: H04L7/08
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To correctly detect a synchronization code even if a false synchronization code are produced. SOLUTION: In this synchronization circuit, a synchronization code detection circuit 2 detects a synchronization code from a digital data series and outputs a synchronization code detection signal. A pseudo-detection signal output circuit 3 outputs a pseudo-detection signal for a time when a succeeding synchronization code is to be detected and a predication signal circuit 4 outputs a prediction signal. A counter circuit 5 counts the number of times when the prediction signal and the synchronization code detection signal are received with coincidence, a comparator circuit 7 compares the count of the counter circuit 5 with a register value of a register circuit 6 and a prediction control circuit 8 outputs a prediction control signal under a prescribed condition from the comparison result.  When there is a temporal deviation between the synchronization code detection signal and the pseudo-detection signal, a detection signal adjustment circuit 9 outputs only a signal that was received earlier.

Title: Engine with pressure wave supercharger
Inventor: KIMURA KIYOMI
IPC: F02B33/44
Filed: 1989-01-31
Abstract: PURPOSE:To prevent loading of a trap chamber due to carbon by installing the carbon trap chamber in the lower bend part bottom of an intake passage lying between a pressure wave supercharger and an intercooler, and also installing a relief valve, which is opened when supercharging pressure higher than waste gate setting pressure, in the discharge port. CONSTITUTION:Intake air mixed with carbon 26 flows toward an intercooler 20, but when it passes through a bend part 25 heading for the lower part of an intake passage 2b at the upstream, the carbon 26 flows into a carbon trap chamber 27 with its own inertia and weight and is collected thereinto. Therefore an inflow of the carbon 26 into the intercooler 20 is thus checked. At time of sudden acceleration when supercharging pressure becomes higher than the setting pressure of a waste gate valve 17, a relief valve 30 in a discharge port 28 of the carbon trap chamber 27 is opened, and thereby the carbon 26 collected in the carbon trap chamber 27 bypasses the intercooler 20 together with a part of the intake air and is discharged to the intake passage 2b at the downstream side.

Abstract: PURPOSE:To prevent a monitor output from varying with wavelength, polarized light, temperature, etc., and improve the reliability of the monitor, and to reduce the size and cost of the optical device by providing a monitor circuit in a waveguide substrate. CONSTITUTION:The output-side optical waveguide 4 of the waveguide type optical device 1 is provided with an S-shaped optical waveguide 20 and a photodetecting element 30 is installed having its photodetection surface opposite the substrate flank 2A of the optical device 1 so that the emitted light of the 2nd bent part 22 is photodetected. The bent part 22 is formed closely to the substrate flank 2A; and the bending radius of the 1st bent part 21 of the optical waveguide 20 is made sufficiently large and the bending radius of the bent part 22 is made desirably small. Part of the light is emitted horizontally at the bent part 22 toward the substrate flank 2A to become monitor light. The quantity of the emitted light is determined depending upon whether the bending radius of the bent part 22 is large or small and there is not any variation with wavelength, polarized light, temperature, etc., so the quantity of monitor light does not vary and the reliability of the monitor is improved.

Title: Vapor cooling semiconductor rectifier
Inventor: ISHIDA SHIGEO
IPC: H01L23/44
Filed: 1982-02-18
Abstract: PURPOSE:To accurately detect leakage and entrance of non-condensing gas in view of preventing a serious fault of apparatus by providing a temperature-pressure converting circuit which inputs a detected temperature and outputs a saturated vapor pressure of refrigerant. CONSTITUTION:When a non-condensing gas is mixed, pressure in a hermetically sealed case rises corresponding to amount of gas mixed. Therefore, an output of the signal converting circuit 10 becomes higher than that in an ordinary condition. On the other hand, a temperature-pressure signal converting circuit 12 is so configurated that it outputs a pressure of refrigerant at a temperature within the hermetically sealed case after the signal conversion and it outputs a pressure determined by refrigerant without relation with entrance of non-condensing gas. Therefore, an output of the temperature-pressure signal converting circuit 12 always shows the pressure-temperature characteristic in the ordinary condition. In this condition, a comparator circuit 13 obtains an output and is capable of operating a fault indication circuit 14.

Title: Monitor television set
Inventor: AMANO TOSHIO
IPC: H04N5/44
Filed: 1989-02-03
Abstract: PURPOSE:To simplify operation by automatically executing input switching operation when a registered command signal is detected and automatically executing turning-on and off control to the power source of a monitor television set so as to be interlocked with a connected AV equipment when the command signal is the power source operation command of the connected AV equipment. CONSTITUTION:In the case of a registration mode, the command signal to be registered is stored to a memory 30 in correspondence to a selected input terminal. In the case of an automatic switching mode, when the command signal is detected and the above mentioned command signal is already registered to the memory 30, switching control is executed by an input select control means 24 so that the input terminal can be selected. When a 'STOP' signal is detected to the AV equipment under operating, the switching operation control is executed so that operation can return to an input selection state just before a 'PLAY' signal to the 'STOP' signal is detected.

Title: Heat fixing device
Inventor: YAMASHITA KEITAROU
IPC: G03G15/20
Filed: 1983-02-17
Abstract: PURPOSE:To shorten considerably a preheating time by providing annular electrodes near both end parts of a pair of heat roll and bringing the electrodes facing oppositely into contact with each other through a feeding brush in the fixing device which is so constituted that a supporting body holding a toner image passes between the heat rolls. CONSTITUTION:Pairs of the annular electrodes 9, 9a, 9b, and 9c consisting of a conductor such as a Cu alloy or the like are provided near both end parts on outside circumferential faces of resistance heating body units 8 and 8a at an interval slightly longer than a prescribed fixing width. When a voltage is impressed to a feeding brush 12, a current is flowed to layers 8 and 8a through individual electrodes because the feeding brush 12 is brought into contact with the electrodes 9, 9b, 9a, and 9c, and heat rolls 1 and 2 are heated together. Since the brush 12 is press-fixed to the individual electrodes through a spring 13, a biting action is caused by the rotation of rolls 1 and 2 to reduce a contact resistance, and thus, to improve the feeding.

Title: Motor
Inventor: HANEDA TOSHIO
IPC: H02K11/00
Filed: 1986-02-07
Abstract: PURPOSE:To reliably control a motor by detecting the magnetic flux of a magnet by a Hall IC to inexpensively manufacture the motor. CONSTITUTION:A winding 2 is formed on a core 1 and a cage-type rotor 3 is provided in a bore side to form a small-sized induction motor. The winding 2 is molded with a resin 4 together with the core 1 to form a stator 5, and brackets 6, 7 are provided at both sides. A substrate 11 is interposed to the stator 5 to attach a Hall IC 12 to one bracket 6, and a magnet 13 is attached to a shaft 10 at a position opposed to the IC. Thus, the IC 12 detects the rotating speed of the rotor 3 to transmit it to a control circuit, which arbitrarily control a voltage applied to the winding 2 to obtain a set rotating speed. Since the IC 12 has therein an amplifier, even if a large noise is mixed-in from the exterior, it is not affected by said noise.

Title: Cell flow rate monitor circuit
Inventor: WATANABE KAZUHIRO
Filed: 1993-02-12
Abstract: PURPOSE:To accurately discriminate a violation even in the case that the time required for arrival of a contracted number X of cells is longer than the period of a counter circuit used as a timer. CONSTITUTION:A cell arrival interruption detecting means 108 confirms whether the time interval of cells arriving before and after may make the time required for arrival of X cells longer than the period of a counter circuit 104 or not; and if this time interval may make the time required for arrival of X cells longer than the period, the confirmation result is reported to a discrimination utilizing information correction means 107A. At this time, this means 107A operates information used for violation discrimination in such direction that it is difficult to discriminate a violation (for example, arrival time information of the oldest stored cell is abandoned), and thereby, a violation is not erroneously discriminated even if the time required for arrival of X cells is longer than the period of the counter circuit.

IPC: B41J2/485
Filed: 1993-02-12
Abstract: PURPOSE:To thin a small picture element obtained by means of dividing a picture element and to make reduction printing possible without the perfect omission of the original original picture element by printing an original picture with the picture elements the number of which is smaller than the (n) specified small elements. CONSTITUTION:A reduction control part 1 successively converts the picture element P of picture data which is serially inputted into the small picture elements p consisting of the eight prescribed picture elements and outputs them to a page printer part 3 (LBP part) as a signal PRINTDT. An oscillator 2 is a clock oscillator stipulating the printing dot width of the small picture elements p and its clock cycle is decided by the main scanning speed of the page printer part 3. Thus, one picture element of the received original printing picture is divided into the eight small picture elements having 1/8 width and the small picture elements are thinned in accordance with a reduction rate so as to execute printing so that reduction printing in a main scanning direction is made possible without the perfect omission of the original picture element only by using a single clock oscillating source.
