Title: Chattering prevention circuit for switch
Inventor: OTA KAZUHIDE
IPC: H01H9/54
Filed: 1994-06-20
Abstract: PURPOSE:To prevent chattering generated in the case of closing a switch, by providing a simple transistor circuit, in addition. CONSTITUTION:When a switch SW is closed from the first contact S1 side to the second contact S2, just as a common COM of the switch SW separates from the first contact S1, A transistor Q2 is turned ON so that A terminal becomes low level. Afterwards, the common COM touches the second contact S2 and the common COM touches the second contact S2 while bounding. Because the transistor Q2 is turned ON, even in the case of generation of bounding, A terminal stays at its low level by the transistor Q2 so as to eliminate any effect of chattering of the switch SW.

Title: Video processor
Inventor: KAMIYA SHINGO
IPC: H04N5/44
Filed: 1999-06-08
Abstract: PROBLEM TO BE SOLVED: To provide a video processor by which the display range of subtitles is detected and masking is executed only there by generating a mask image for covering blocks based on the density of specified color dots, which is decided to be the subtitles blocks, and compositing the mask image with the inputted image. SOLUTION: A signal fetching part 1 detects the 100% white dots, which seem to be subtitles telops and inputs the density information to a subtitles deciding part 2. The part 2 decides the block, where the subtitles are displayed based on density information inputted from the fetching part 1 and the timewise change situation of the density information and indicates a signal processing part 3 to generate a video signal for masking the area, where the subtitles blocks are distributed. The part 3 generates the mask image only for the subtitles areas, composites it with the video signal to be inputted and then outputs it to a monitor. Thus, the video where the subtitles telops are hidden by the mask image is displayed on the monitor.

Title: Starting circuit
Inventor: HIRAHARA MINORU
IPC: G05F1/46
Filed: 1980-11-17
Abstract: PURPOSE:To obtain the stable output voltage although no coincidence is obtained for the input time point between the positive and negative DC voltages, by monitoring the DC input voltage with the reference voltage which is higher than each of the positive and negative voltages and lower than the total value of these  voltages. CONSTITUTION:The positive DC voltage V1 is supplied between input terminals 1 and 2; and the negative DC voltage V2 is supplied between input terminals 2 and 3. The DC voltage V5 is delivered between output terminals 4 and 5. When only the voltage V2 is applied at a time point T1, the DC input voltage V4 is set lower than the breakdown voltage of a constant voltage diode ZD. As a result, no current flows to the diode ZD plus resistances R1 and R2, and accordingly a transistor TRQ3 is interrupted to supply no voltage to a constant voltage control circuit 6. Thereafter, the voltage V1 is applied and accordingly the voltage V4 exceeds the breakdown voltage of the diode ZD. Thus the circuit 6 has the normal operation to obtain the stable DC output voltage V3 between the terminals 4 and 5.

Abstract: PURPOSE: To obtain the steady sine wave alternating output with no distortion of waveform, by giving an on/off control to the alternating input voltage with a certain high frequency and varying this on/off time ratio in accordance with the output voltage of the output winding of an output transformer.  
     CONSTITUTION: The alternating input voltage applied between the input terminal a 1  and b 1  is applied to the output transformer 3 via the filter circuit 2 which eliminates the high frequency component produced by the on/off action of the switching circuit 1. Thus a high-voltage alternating output is obtained from the output terminals (a 2 ) and (b 2 ). The output corresponding to the voltage between the terminals (a 2 ) and (b 2 ) is obtained from the control winding T of the transformer 3 and then applied to the comparator 8 via the rectifying circuit 4 along with the output given from the reference voltage setting circuit 6 and the saw-tooth wave supplied from the saw-tooth wave oscillation circuit 7. Then an on/off control is given to the circuit 1 via the drive circuit 9 and with the duty ratio according to the difference between the output voltage and the reference voltage.
