Title: Igniting apparatus for internal-combustion engine
Inventor: TOYAMA KOUICHI
IPC: F02P15/12
Filed: 1982-02-22
Abstract: PURPOSE:To prevent malfunctioning of an ignition coil, by shaping the wave form of an output signal of a signal generator at the time of starting, and driving an output circuit by the output of a noise removing circuit which reduces the pulse width of the output signal of the wave-form shaping circuit for a prescribed time. CONSTITUTION:The igniting apparatus of this invention comprises a noise removing circuit 3 which is furnished with an output signal of a signal generator 1 after its wave form is shaped by a wave-form shaping circuit 2 and reduces the width of the output pulse of the wave-form shaping circuit 2 for a prescribed while. The noise removing circuit 3 is operated only at the time of startig with a ''start'' detecting switch 6 being opened. Other than at the time of starting, however, a transistor (Tr) 71 of a prohibition circuit 7 is energized via a resistance 72 by turning a switch 6 ON. Thus, an output signal of the wave-form shaping circuit 2 is applied directly to a Tr 36 of an output circuit 4 via a resistance 21 and a Tr 34 without delay. By thus removing the noise components having a relatively high frequency and a short pulse width at the time of starting, it is enabled to prevent malfunctioning of an ignition coil 5.

Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To keep a D.C. current from flowing from an X-ray tube to a filament transformer by cutting a D.C. current which flows from a D.C. high voltage power supply through an X-ray tube to shunt and flow into a D.C. high voltage power supply to which negative D.C. high voltage is applied through a secondary coil of the filament transformer. SOLUTION: To prevent D.C. biased magnetization of a filament transformer T1 due to the shunt current of an X-ray tube direct current, a capacitor C is connected in series between a filament XTb of an X-ray tube XT and one end T1a of a secondary coil of a transformer T1. By the capacitor C, a direct current from the X-ray the XT passes only a high voltage cable CB1 without passing through the secondary coil of the transformer T1 and flows into a D.C. high voltage power supply E2. Accordingly, a ferrite core and a troidal core of the transformer T1 are kept from being magnetized a direct current from the X-ray tube XT.

Title: Hydraulic brake pressure controlling valve for vehicle
Inventor: MIZUSAWA MITSUO
IPC: B60T8/28
Filed: 1979-03-12
Abstract: PURPOSE: To distribute braking force appropriately in response to the load carried on a vehicle, by constituting a brake force controlling valve by a pressure-reducing valve whose set pressure is determined by a spring, a control piston for normally keeping the pressure-reducing valve in its opened state and for delaying the valve closing timing, and a weight valve for closing a connecting oil passage through detection of deceleration of the vehicle.  
     CONSTITUTION: In case that the vehicle is empty, deceleration is small so that weight valve 28 is placed in its seat 27 and closes oil passage 21 communicated to hydraulic chamber 22. Therefore, control piston 23 is not operated since spring force is greater than hydraulic pressure. After hydraulic pressure in input chamber 8 has reached a certain value along with increasing of mastering pressure, oil pasage 10 is repeatedly opened and closed by the repetition of movement of piston 7 that is caused depending on the relationship between the force of spring 16 and pressure difference in hydraulic chambers 8 and 9 having different pressure-sensitive areas, and a reduced pressure is transmitted to rear-wheel brake Br. In case that the vehicle is fully loaded, however, deceleration becomes high. Therefore, hydraulic pressure is acted in chambers 8, 22 before weight valve 28 is set into operation, so that control piston 23 is urged forward against the force of spring 26 and valve body 11 is also moved forward. Resultantly, valve closing timing of valve body 11 is delayed and braking force is distributed appropriately to the front and rear brakes.

Title: Heat fixing device for electrophotographic device
Inventor: MORI RIYOUHACHI
IPC: G01K1/14
Filed: 1986-02-14
Abstract: PURPOSE:To obtain high-response performance by providing a noncontact temperature sensor used for a temperature detecting means nearby a heat roller and providing a cover which controls convection heat on the rear side of the noncontact temperature sensor. CONSTITUTION:The cover 9 prevents the air between the heat roller 1 and a thermistor 4 as the noncontact temperature sensor from moving the rear side of this thermistor in the heat-up period of the heat roller 1 to reduce the convection of air, and receives radiant heat from the heat roller 1 and conducts it to the part of the thermistor 4 contacting the cover 9. Further, the cover also controls a flow of air at the periphery of the thermistor so as to prevent the detected temperature of the thermistor 4 owing to the convection of the air at the periphery of the heat roller which is generated when the heat roller 1 makes one turn during fixing operation after the heat-up period. Consequently, the heat-up period of the heat roller is shortened to perform stable fixation temperature even during operation.

IPC: H04N5/46
Filed: 1992-01-20
Abstract: PURPOSE:To prevent the ringing occurring on a CRT display screen by turning off the scanning speed modulation of an electronic beam at a boundary part of the received images. CONSTITUTION:In regard to the high-definition TV signals sent from a signal converting circuit 12, the horizontal synchronizing scanning time is compressed by an image converting means 13 in a rate of (4/3)/(16/9) and the converted video signal containing the black level images equivalent to the compression time before and after its position is inputted to a high-definition TV receiver 14 through an output terminal 13a. Meanwhile the luminance signal is inputted to a speed modulation switch circuit 18 through a luminance signal output terminal 13b. In the circuit 18, a control signal is outputted to a terminal 13c from the means 13. Thus the circuit 18 is controlled. The control signal turns off the circuit 18 at the parts near the right-left both end boundary parts 102e and 103e of a compressed image where the luminance signal has a large changing degree. Therefore the ringing never occurs at the parts 102e and 103e. As a result, the hard-to-see images due to the ringing can be eliminated.
