Title: Sinusoidal wave generator circuit
Inventor: NAKANO KATSUAKI
IPC: H02M7/537
Filed: 1982-03-25
Abstract: PURPOSE:To generate an accurately sinusoidal wave by interrupting a switching circuit according to a control signal at every 1/2 period of the period of the switching circuit in synchronization with an oscillator. CONSTITUTION:A switching circuit 7 which is turned ON or OFF at the prescribed period is connected to the primary coil of a transformer 8 which does  not have a leakage bus for outputting a waveform necessary from the secondary coil. An oscillator 3 outputs a duration signal which has the same frequency as the switching circuit 7 and a period shorter than the half period of the switching circuit. A drive circuit 1 is controlled by the signal of the oscillator 3 to charge or discharge a condenser 6 at the prescribed time constant, and controls the conduction of the switching circuit 7 with the voltage across the condenser 6. A shut-off circuit 11 generates a control signal synchronously with the oscillators 3 at every 1/2 period of the period of the switching circuit 7, and shuts off the switching circuit 7 with the control signal.

Title: Gun-type burner
Inventor: ARIMA SATOSHI
IPC: F23D11/24
Filed: 1987-03-03
Abstract: PURPOSE:To stabilize the burning by disposing an ignition electrode in a portion of the combustion air stream caused by a fan where the velocity component parallel with the plane made by the blow tube end is the smallest possible to a practical extent. CONSTITUTION:When the start switch is turned ON, a fan 21 rotates to cause combustion air to flow to the burner head 24 and to a combustion part 26 after being smoothed by multiple air flow smoothing holes 27 in a cylindrical blow tube 28. When the supply air rate reaches a certain level, a spark is generated at an ignition electrode 31, and fuel is jetted out of a fuel injection nozzle 30. The burning is then started in the combustion part 26 as the flame is held by a stabilizer 25. Because the dynamic pressure is relatively low in the part covering the lower right to the right of the end of the flow tube 28, and the speed of combustion air is relatively low in the plane parallel with the end of the blow tube 28, the ignition electrode 31 does not greatly disturb the combustion air flow along the plane parallel with the end of the blow tube despite the fact that the ignition electrode 31 projects from the end of the blow tube 28 into the fan case.

IPC: H04L1/00
Filed: 1989-02-27
Abstract: PURPOSE:To identify whether or not there is malfunction in a time decoding circuit by a method wherein time indication 1 second before comprising second, minute, hour and date is incremented by 1 second to compare the current time with the 1 second incremented time indication so that based on the comparison results an error of time information converted into digital information is checked. CONSTITUTION:Time information S1 in IRIG-B format is input to a time decoding circuit 1 and decoded into digital time information comprising second, minute, hour and date by the time decoding circuit 1. The decoded digital time information is input to a counter 2, incremented by 1 second and this incremented time information is stored in a register 3. The time stored in the register 3 and next time S2 decoded by the time decoding circuit 1 are compared with each other by a comparator 4 and if the two time indications coincide with each other conversion in the decoding circuit is assumed to be correct otherwise it is regarded as an error to have an error signal S3 to be output. This can identify whether or not there is malfunction in the time decoding circuit.

The sizes in the height directions of respectively components are so determined that the sum (a) of the height from the lower end of the valve member 9 to upper end in which the valve member is to be brought in slide-contact with the through hole peripheral surface and the maximum compression height of a compression spring 15 may be larger than the height (b) from the bottom wall upper surface of a cylindrical casing 13 to the lower surface of a lower surface plate 2, and that it may be smaller than the sum (b)+(c) of the thickness (c) of the lower surface plate 2 and the height (b) in the stroke limit state of the valve member 9. Therefore the hard spring characteristic can be realized even if oscillation is increased.

Filed: 1987-03-02
Abstract: PURPOSE:To obtain images of less flicker by alternately arranging display areas on which the image for the right eye and the image for the left eye are displayed so that their planes of polarization are orthogonal to each other. CONSTITUTION:The screen on a display part 100 is divided to plural narrow and long areas 101 and 102 in the horizontal direction, and the area 101 which outputs the light polarized in the horizontal direction of an arrow A and the area 102 which outputs the light polarized in the vertical direction of an arrow B are alternately arranged. Two images for the right eye and the left eye having parallax are simultaneously displayed on areas 101 and 102, and for example, the image for the right eye is displayed on the area 101 and the image for the left eye is displayed on the area 102. A polarizing plate 201 of polarizing glasses 200 permits the light outputted from the area 101 of the display part 100 to pass through but intercepts the light outputted from the area 102. Meanwhile, a polarizing plate 202 permits the light outputted from the area 102 to pass through but intercepts the light from the area 101. Consequently, the image for the right eye on the area 101 and the image for the left eye on the area 102 are seen with the right eye and the left eye individually and simultaneously, and two images having parallax on the display part 100 are synthesized to obtain a stereoscopical image.

Inventor: NEMOTO TAKEO
IPC: G01M3/20
Filed: 1994-03-18
Abstract: PURPOSE:To detect the point and direction of gas leak in a short time by arranging a plurality of leak detectors thereby detecting every part of a gas. CONSTITUTION:The gas leak detector 6 comprises detectors A, B and C and helium gas leaked through the bottom of a liquid helium vessel 3 is diffused into a vacuum vessel 4. Signals from the detectors A, B and C are presented on a leak detection display 7 and when the magnitudes of output signals are in the order of C, B, A, a decision is made that the leak point is located on the right side of the detector C and then the detector 6 is shifted to the right. When the output signal from the detector B is highest and the output signals from the detectors A and C have a same level, the detector 6 is stopped and a decision is made the leak point is located substantially in the center of the detector B. When the gas leaks at a rate high enough to cause abrupt increase of pressure in the vessel 4 immediately upon movement of the detector 6, the leak point is rounghly predicted by observing the temporal variation of output signals from the detectors A, B and C.

Title: Time-axis inversion device
Inventor: TAKEUCHI YASUTO
IPC: H03H9/25
Filed: 1980-04-14
Abstract: PURPOSE:To invert the time axis by returning a traveling signal wave to its arrival direction, by causing an impulsive ultrasonic wave to strike the signal wave. CONSTITUTION:Electric signals inputted from terminals 2 and 2' are converted into surface wave (SAW) by transducer 1. Then, SAW travles straight on the surface of sound-transmissible substrate 4 from left to right. Pulse generator 7, on the other hand, actuates ultrasonic-wave generating means 5 to generate BULK waves. The BULK waves strike the traveling SAW at the same time over the entire surface of sound-transmissible substrate 4. Once both those waves strike mutually, the nonlinearity characteristic to SAW provides integration effect. As a result, SAW is separated into a component which is further traveling ahead and components which are traveling back to terminals 2 and 2'. Those traveling-back components are led out from terminals 2 and 2' to obtain a signal having the time axis inverted, thereby performing time-axis inverting operation.
