IPC: F02P3/04
Filed: 1995-04-14
Abstract: PURPOSE: To provide size reduction without degrading the reliability of an ignition device for a current shut-down type internal combustion engine. CONSTITUTION: A DC resistance value Rp of the primary winding of an ignition coil 12 is set so that the maximum value ILmax of a primary current IL of the ignition coil supplied from the battery of output voltage Vb may not exceed the maximum rated current of a power transistor Q1 which is turned on and off by an ignition signal Sg if the power transistor Q1 exceeds ON time tON scheduled at the time of regular ignition operation and is kept in a continuously energizing condition. The ON time tON of the ignition signal Sg is then kept such a length as the voltage Vp which an ignition plug 13 requires can be obtained.

Title: Transmission system for color television signal
Inventor: SHIYUDOU KOUICHI
IPC: H04N11/04
Filed: 1984-05-31
Abstract: PURPOSE:To eliminate the generation of a DC component in a transmitted digital code even for a signal which contains the same information repeatedly for every color synchronizing signal and to eliminate deterioration in waveform even on a transmission line which transmits no DC component by inverting the signal at a period which is an integral or simple multiple of the color synchronizing signal. CONSTITUTION:An NTSC color television signal from the input terminal 1 of a transmitting device is supplied to an encoding circuit 2 for linear PCM conversion in synchronism with a clock signal inputted to a terminal 12, generating one-word, eight-bit parallel digital codes. The digital codes are inverted in sign through a sent code inverting circuit 9 at intervals of four words. The output codes are sent out as a digital signal to a terminal 10 through a multiplexing circuit 4, parallel converting circuit 7, and interface 8. A receiving device extracts a received signal by an interface 22 from a reception input to a terminal 21, and the signal is passed through a series converting circuit 23 and a demultiplexing circuit 24 to obtain eight-bit parallel digital codes. The digital codes are inverted by a received code inverting circuit 25 at intervals of four words and decoded by a decoding circuit 26 to obtain a color television signal.

Title: Programmable counter
Inventor: KIKUCHI HIROYUKI
IPC: H03K23/66
Filed: 1978-09-16
Abstract: PURPOSE:To realize the programmable counter of complementary MOS constitution small in the propagation delay time and less in the number of circuit elements, by constituting AND, OR and exclusive NOR gates with NAND and transmission gates. CONSTITUTION:When the LOAD terminal is high, the output of the NAND gate 22 is high. If either of CEP or CET terminal is low, FF33 is held at prestage. But, if the CEP and CET terminal are all high, FF33 is inverted and the count is advanced. The propagation delay from the operation of FF33 when the count is made until the D input is confirmed consists of the delays in the transmission gate 25 and NAND gates 31 and 32. Accordingly, the propagation delay can be made less. Further, the number of gates can remarkably be reduced.

Abstract: PURPOSE: To prevent excessive engine roughness caused by pollution substance by compensating a second control input for an ignition timing control device with respect to the variation that is impressed by a first control input for a mixture control device. CONSTITUTION: Based on suction pressure generated by a crank sensor 10a, engine speed calculated by a speed calculator 13 and a sensor 10b, a schedule 14 sets a fixed ignition angle feed value, it is compensated by a controller 22 with the difference 20 of a slope demand generated by a schedule 16 and engine speed slope value generated by a detector 19, and is for input to an ignition device 12.

Title: Locking and unlocking system of terminal device
Inventor: KUBO MITSUHIRO
IPC: G06F15/00
Filed: 1983-06-24
Abstract: PURPOSE:To evade the ending of a job due to an unlock or interrupt input from the third party in a keyboard of a terminal device by locking softwise a terminal device in response to the registration and key input of a lock command or input of a private keyword. CONSTITUTION:When the lock command is inputted, a signal routine is called in a mode wherein an interruption is ignored to inhibit interrupt input by the third party and also request keyword input. When the private keyword specified by and known to only an operator is inputted, this is stored in a buffer and the terminal becomes ready to input data. Data when inputted is compared with the contents of the buffer, and when they don't coincide with each other, the locked state is displayed on a display device and no keyboard input is accepted. Therefore, even when an interruption is caused with a break key, that is ineffective. When the both coincides with each other, on the other hand, it is judged that the terminal is unlocked and control is passed to the job in process.

Abstract: PURPOSE: To obtain the device which transmits a driving shaft to one shaft by a method wherein the driving shaft is automatically connected to the shaft when the revolution of the other shaft is obstructed under a condition that the driving shaft is connected to the other shaft.  
     CONSTITUTION: When turning a knob 1 in the arrow head direction, a driving shaft 2, a block 6, seesaw mechanisms 70W77 are rotated in the same direction, and a concentration filter 10 is turned with the second shaft 5 by connection between the projection 74 and a V-shaped groove 5a with the revolution. When a projection portion 8 is contacted with a stopper 9, the revolution of the shaft 5 is obstructed, but when the knob 1 is further rotated in the arrow head direction the projection 74 is lifted from the V-shaped groove 5a by the obstruction of the rotation of the shaft 5 and placed on an outer circumferential surface of the shaft 5. When the projection 73 is positioned at a location of a V-shaped groove 4a, the projection 73 automatically falls in the V-shaped groove 4a by the function of the spring 77 and the ball 75. Thus, the first shaft 4 is rotated in the counter-clockwise direction by connection between the projection 73 and the V-shaped groove 4a, and a potentiometer 14 is turned through gears 3, 13.
