Title: Liquid crystal driving circuit
Inventor: AOKI KAZUO
IPC: G09G3/18
Filed: 1988-01-20
Abstract: PURPOSE:To simplify the constitution of a display system and to reduce the burden on a display controller by generating a liquid crystal remote control signal in a common driver in accordance with a liquid crystal driving waveform AC converted signal. CONSTITUTION:The display controller transmits a liquid crystal driving waveform AC converted signal (b) corresponding to the common display timing period and a common signal shift clock (a) to a liquid crystal driving circuit in accordance with the display duty ratio. The liquid crystal driving circuit internally generates a common signal in a common signal generating circuit 4 in accordance with two signals transmitted from the display controller. The generated common signal is not only successively shifted synchronously with the common signal shift clock (a) by an internal shift register but also converted to a liquid crystal driving waveform and is outputted to a liquid crystal panel. Thus, only two interface lines are required between the display controller and the liquid crystal (scanning side) driving circuit to simplify the wiring of the system, and the burden on the display controller is reduced.

Filed: 1991-01-31
Abstract: PURPOSE:To prevent scan lines from being inverted by difference between respective odd-numbered and even-numbered fields by using one field memory. CONSTITUTION:A one-field memory 1 is provided to store video signals for one field, and a reset signal generation part 2 is provided to control write and read. The reset signal generation part 2 is equipped with a V separation circuit 21, V latch circuit 22 to output the transformation field pulse of a duty ratio 263:262, AND circuit 23 to output a mask signal by calculating a logical condition for getting '1' in the case of the odd-numbered frame and getting '0' in the case of the even-numbered frame, 262 counter 24, OR circuit 25 to output a write reset signal, write edge detection circuit 26 and read edge detection circuit 27. Thus, since the reset signal generating means adjusts the write timing of a write synchronizing signal based on a read synchronizing signal and outputs a write reset signal and input video signals are written in the one-field memory at write timing specified by this write reset signal, the scan line is prevented from being inverted.

IPC: B61L25/02
Filed: 1981-01-29
Abstract: PURPOSE:To improve the reliability of a vehicle by controlling the travel of the vehicle and the monitor of the position by a controlling device provided on the ground. CONSTITUTION:When an initial sensor 2 confirms the position of a vehicle, an initial value is set in a distance integrating counter 105.

Title: Semiconductor laser device
Inventor: WATANABE SEIICHI
IPC: H01S5/026
Filed: 1986-01-24
Abstract: PURPOSE:To manufacture a semiconductor laser device with a photodiode for monitor operating even when a power supply having both polarity is not used by working the photodiode and a semiconductor laser diode by a single power supply. CONSTITUTION:Laser beams emitted from a laser-beam outgoing end surface 9 for an active layer 7 are received by a photodiode 3 and monitored. laser beams emitted from a laser-beam outgoing end surface 10 are projected outside a semiconductor laser device as original laser beams. Since the semiconductor laser device electrically isolates a section, with which a laser diode 5 is bonded, by a P-type semiconductor region 4, there is no relationship of electrical connection between the photodiode 3 and the laser diode 5. Accordingly, the photodiode 3 and the laser diode 5 can each be connected to a power supply separately, and even a positive power supply and even a negative power supply can also be used without hindrance.

Abstract: PURPOSE:To flatten the shape of coating material, improve the flatness of a film after etching, and prevent the short circuit and discontinuity of a conducting layer on the film, by spreading insulating material twice or more. CONSTITUTION:A metal wiring 11 is formed on an Si substrate 14; resist 13 is spread once on an insulating film 12 and baked; resist 15 is again spread and baked; the spreading and the baking or resist are repeated until the shape of the resist becomes flat. After flattening, RIE is performed and the resist is eliminated, thereby obtaining a flattened insulating film 16, on which an insulating film 17 is again deposited. Since the insulating film is excellent in flatness, the short and circuit discontinuity of a metal wiring formed on said film are scarcely generated.

Title: Method for controlling ram down resetting off punch press
Inventor: MIZUKADO MASAYOSHI
IPC: B30B15/14
Filed: 1986-01-23
Abstract: PURPOSE:To automatically reset a ram to a top dead point even if a ram down arises by putting a clutch into a half clutch state by a half clutch inducing means to rotate a driving shaft at a low speed when the detection signal for the ram down is detected. CONSTITUTION:A sensor 47 does not detect a dog 15c and therefore, a signal S1 is not outputted if the ram 17 fails to stop at the standby position, e.g., top dead point, namely, when the ram down arises by a certain cause. The generation of the ram down is then checked by a main control part 49 and the working program under execution is interrupted. Compressed air is thereupon supplied to the clutch 36 so that the driving shaft 15 is rotated at the low speed by the braking effect by a brake 37 and the half clutch driving of the clutch 36. The ram 17 is thereby slowly moved in an arrow D direction and after the ram passes the bottom dead point, the ram is in this time moved backward in the arrow C direction until the ram arrives at the top dead point, when the dog 15C faces the sensor 47 and the signal S1 is outputted from the sensor 47 to the main control part 49. The resetting operation is thus completed.

Filed: 1979-02-08
Abstract: PURPOSE: To ensure the free programming for recording of the aural contents to be reproduced repetitively by securing memorization for the serial coded signal for addressing into the record gap of the magnetic tape.  
     CONSTITUTION: The address information is written previously into RAM13 via keyboard 11 prior to recording of the text contents. Then tape mechanism 15 is driven forward, and CPU10 reads the information of RAM13 and converts it into the serial binary coded signals through parallel-serial signal conversion circuit 18 for writing onto the magnetic tape via encoder 19 and record/reproduction head 23. In case the repetitive reproduction is desired, the address to be reproduced and the following address are designated via the numerical keys after pushing the function key for repetition. Thus the magnetic tape is wound quickly and forward to secure the agreement for the address to be reproduced. When the agreement is secured with end of the reproduction and the agreement secured for the next address, the tape is wound backward quickly and automatically. And the reproduction is repeated again when the agreement is secured for the addresses to be reproduced.

Abstract: PURPOSE:To eliminate need to cut the blank part of recording paper which is discharged from a facsimile equipment newly by discriminating record of A4-size width with an initial recording paper width detection signal and cutting the unnecessary part of B-4 size recording paper after recording automatically. CONSTITUTION:When the record of A4 size is received on B4-size recording paper and the recording paper is discharged, the recording paper width detection signal S is inputted to a control circuit 7, which knows that the record of A4 size is received on the B4-size recording paper from the recording paper width detection signal S and puts a solenoid 6 in operation to lower a pressure plate 4. Then there is no pressure from below so far and then the recording paper 8 which runs on the blade of a cutter 1 between paper discharge roller 2 and 2 is clamped between the cutter 1 and pressure plate 4 to receive a shearing force, so that the paper is cut. The recording paper 8 is moved by the paper discharge roller 2 and 3 while cut, so recording paper of constant width is cut off to the overall length of one sheet of received record.
