Title: Magnetic picture recorder and reproducer
Inventor: YAMAMOTO MASAKAZU
IPC: G11B15/00
Filed: 1981-09-30
Abstract: PURPOSE:To prevent the damage of a magnetic tape in case the power supply is interrupted while the reproduction is carried out at a high speed by a capstan motor, by driving a reel motor with the electric power of a capacitor after the interruption of power supply and then stopping the reel motor simultaneously with the capstan motor. CONSTITUTION:The DC obtained by rectifying the AC supplied from a power supply terminal 1 through a diode 2 is supplied to a motor driving circuit 3. Thus a reel motor 7 is turned in a designated mode 6a or 6b. At the time, the DC supplied from the diode 2 is applied to amode holding circuit 4, and a capacitor 5 is also charged. When the power supply is interrupted in a high-speed reproduction mode or a rewind mode, the mode of the circuit 4 of that moment is held by the signal of a power supply interruption detecting circuit 8. The held mode is then supplied to the circuit 3. The motor 7 is turned by discharging the electric power of the capacitor 5 via the circuit 3 and in the held mode and then stopped almost simultaneously with a capstan motor. This can prevent the damage of a magnetic tape.

Title: Dry etching apparatus
Inventor: SUDO KOJI
IPC: H01L21/3065
Filed: 1986-07-02
Abstract: PURPOSE:To ensure the detection of a finish point, in an etching apparatus, in which the finish point of etching is detected by sensors, by scanning the entire surfaces of wafers by using a plurality of sensors, and detecting the finish point. CONSTITUTION:Wafers 1a-1h are set on a lower electrode 3 in a chamber 6. After etching gas is introduced, high-frequency power is applied between an upper electrode and the lower electrode, and plasma etching is started. Sensors 5a-5d scan all parts of the inside of the chamber 6 and wafers 1a-1h. Light emitting intensity of Al in emission spectrum in plasma 4 is detected and applied to a finishpoint detecting unit 7. The finish-point detecting unit 7 detects the finish point of etching based on the change in light emitting intensity of Al. At this time, since a plurality of the sensors are used, the emission spectrum at each wafer position can be obtained even if the wafer is located at any position in the chamber. Therefore, the detection of the finish points of all the wafers can be ensured.

Abstract: PURPOSE:To reduce considerably the irregularity of a recording scan on a readout original by arranging an arithmetic frame so as to contain processing picture elements on a picture element array plane, and providing an image signal arithmetic part which obtains an image signal by adding the image signal of picture element in the arithmetic frame. CONSTITUTION:An arithmetic frame decision part 18 decides on the size of the arithmetic frame of an arithmetic scan on a plane on the basis of pieces of pitch information sent out of a readout scan pitch setting part 15 and a recording scan pitch part 17. The image signal arithmetic part 19 performs specific logical arithmetic as to all picture elements in the arithmetic frame adjacent to processing picture elements on the basis of the control of the decision part 18 and a sampling signal sent out of a timing generation part 13. In this case, the logical arithmetic is so performed that an extremely fine picture area for one picture element on the original 2 which is set with a readout scanning window 9 is set equal to recording scan pitch, and then an impulse of density due to unevenness of recording scanning is average to obtain a readout image signal from which the unevenness of the recording scan is removed.

Title: Watch dog timer circuit
Inventor: KUMAMOTO HIROBUMI
IPC: G06F11/30
Filed: 1988-06-25
Abstract: PURPOSE:To secure strict monitoring capacity for a watch dot pulse abnormality by setting a periodical monitoring period T1 for a peak watch dog pulse longer than a monitoring period T2 for the watch dog pulse except it. CONSTITUTION:After a CPU 10 is reset, a peak watch dog pulse 12 generated by the CPU 10 through a time-up time variable setting circuit 13, set a time-up time T of a watch dog timer circuit II to T1. For this reason, even when the circuit 11 passes through from t0, the circuit does not generate the resetting signal, a peak watch dog pulse is inputted by t1, and then, it is reset by this and a counting action for the next watch dog pulse is started. This depends on the fact that a deciding circuit 12 makes the time-up time variable setting circuit 13 reset the time-up time T of the watch dog timer circuit 11 to the T2 shorter than the T1.

Title: Television receiver
Inventor: KITANO YOSHIHIRO
IPC: H04N5/45
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To simultaneously display two images of a double densed signal and 1/2 video signal on the same picture by producing 1/2 video signal that thins out the number of lines which every two lines reproduces half video of a screen. SOLUTION: An output S2 of a flip-flop circuit 15 outputs a pulse that is subjected to 1/2 frequency division and an output S3 of a monomulti circuit 16 outputs a high pulse of half period of a horizontal scanning period. An AND operation circuit 17 synthesizes both of the pulses and produces a control signal S4. When image elimination is applied to a double densed signal which inputs the signal S4 to a circuit that performs image elimination, a field image that is eliminated every two lines is produced. Then, the number of lines of half period of the horizontal scanning period is eliminated every two lines. Because a 50 Hz or 60 Hz normal signal is produced in a pseudo manner in this way, a deflection circuit does not have to be changed at all and both the double densed signals and 1/2 video signal can be shown on the same picture.
