IPC: G09G3/36
Filed: 1990-01-17
Abstract: PURPOSE:To make well dark clip operation without decreasing an remaining image canceling effect by controlling a dark clip circuit to disable in the state in which a differential signal is generated in an remaining image canceling circuit in correspondence to the fall of an input video signal. CONSTITUTION:Whether data is positive or negative is detected by the uppermost digit of the differential signal outputted from a subtractor 4 in a circuit RIC when the data handled in the remaining image canceling circuit RIC is the complementary number of 2. A horizontal synchronizing signal of a negative polarity is supplied to a horizontal synchronizing signal terminal 9 and, therefore, the numerical number selectively outputted with the data of the prescribed bit number supplied from an output terminal 8 of the circuit RIC to a dark clip circuit 11 as address is outputted as the numerical value of the state in which this value is not dark clipped to an output terminal 12 when the circuit 11 detects that the data is negative, i.e. when the differential signal is generated in the circuit RIC in correspondence to the fall in the input signal and in the period of the horizontal synchronizing signal.

Title: Starter
Inventor: YAMAGUCHI KAZUHIRO
IPC: F02N15/06
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To provide a starter having the outside diameter of an existing motor, using parts of the existing motor, and having a simple structure in which a magnet switch is not projecting outside the motor. SOLUTION: A magnet switch 6 is arranged on the opposite side to a pinion 3 of a motor 2. When the magnet switch 6 is electrified, a plunger 22 is axially moved. This plunger 22 is connected to one end 5a of a lever 5 through a connecting means 31 passing through a clearance of a fixed magnetic field 12. When the plunger 22 is axially moved, the other end 5b of the lever 5 pushes a pinion moving body 4 to a ring gear side. Since the magnet switch 6 is arranged on the opposite side to the pinion 3 of the motor 2, and also since the connecting means 31 passes through the fixed magnetic fields 12, the magnet switch 6 is prevented from projecting outside, the existing motor 2 can be used, and the structure can be simplified.

Title: Detection of insulator string snow lying
Inventor: OGAWA MASAHIDE
IPC: H01B17/00
Filed: 1989-01-18
Abstract: PURPOSE:To automatically detect snow lying by installing a transmitter or transceiver in one side across an insulator string, and a receiver or a reflector receiving or reflecting the output wave transmitted from the transmitter or transceiver in the other side. CONSTITUTION:The transmitter 1 the output wave of which is an ultrasonic wave is installed on the arm 4 of a steel tower 3 so that the output wave 5 transmitted from the transmitter 1 travels above the upper part of an insulator string by a given height, and a receiver 2 is arranged with its position adjusted so that the wave 5 above an anchor clamp 7 can be received. The wave 5 is constantly transmitted from the transmitter 1, and travels intact above an insulator string 6 to be received with the receiver 2. When the snow lying having more than a given height exists on the string 6, the output from the transmitter 1 is interrupted with the lying 8 to become unreceivable with the receiver 2, and the snow lying is detected. Thus the snow lying can automatically be detected.

Title: Ignition timing control method of engine
Inventor: KAJITANI KATSUYUKI
IPC: F02D43/00
Filed: 1991-01-29
Abstract: PURPOSE:To check the discharge of NOx so effectively as well as to improve the extent of fuel consumption or the like by advancing the ignition timing so far as the rich side of an air-fuel ratio is detected by the output voltage of a second oxygen sensor at the specified load area. CONSTITUTION:When an engine is in a specified partial load area and an air- fuel ratio of mixture is lean, ignition takes place at a time little delayed from the optimum ignition timing as usual, and a generating value of NOx is thus checked. When the mixture is rich, a reducing action by a three-way catalyst in a catalytic converter 14 becomes activated, and an emission control rate of NOx is maintained at the high value almost the same as that in a theoretical air-fuel ratio. Therefore, when the air-fuel ratio of mixture varies from lean to rich at the partial load area, the ignition timing comes to be advanced to the optimum ignition timing side according to intake pressure in consequence, but the discharge of NOx is made checkable so effectively. Moreover, if the ignition timing is advanced, fuel consumption and output power, etc., are improbable as well.

Title: Surface defect inspection device
Inventor: MIHASHI HIDEO
IPC: H01L21/66
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To detect surface defect of a silicon wafer and judge its sort. SOLUTION: When a white illumination light 1 is spectrally separated by a prism 2 and cast on a surface to be inspected 5 upon convergence made by a condenser lens 4, a plurality of beams of light having different wavelengths are cast on the surface 5 at different angles. A two-dimensional color sensor 7 photographs the surface 5 through a photographing lens 6 and outputs color image signals ar, ag, ab of R, G, B. In case where the surface includes a defect having a gradually inclining angle, only the light of red wavelength projected at an angle nearest the perpendicular is reflected in the direction of the photographing lens 6, so that reddish photo is obtained. In case where the surface includes a defect having a large inclination angle, the violet rays projected at an angle nearest the horizontal are photographed.  That is, each defect is photographed in different color depending upon the sort of the defect. Thus the defect detection is conducted by an image processing part 8, and the sort of the defect is judged according to the color information.

Title: Clock radio with voice synthesization
Inventor: HAGITANI SHINICHI
IPC: G04G13/00
Filed: 1982-01-26
Abstract: PURPOSE:To generate a continuous voice with a simple construction by controlling the startup of a voice synthesizer with the rectification of the voice signal therefrom. CONSTITUTION:A voice signal with a voice synthesization circuit 5 and a voice signal amplification circuit 6 is applied to a speaker 14 while rectified with a rectification circuit made up of capacitors 7 and 10, diodes 8 and 9 and the like to generate a high-level rectified output, which turns off a transistor 12. Consequently, a starting signal applied to the circuit 5 through the transistor 12 goes to so high a level that the circuit 5 fails to start and hence, the synthesized voice signals are outputted continuously. The outputting of a voice signal for one phrase or the like ends and after a specific time according to a time constant passes, the rectified output goes to a low level. This allows the transistor 12 to be turned on to apply a low level starting signal to the circuit 5 for restarting. Thus, it is possible to obtain a clock radio with a voice synthesization which can generate a continuous voice with a simple construction.
