Title: Ignition-timing controller for internal combustion engine
Inventor: OSANO HISASHI
IPC: F02P5/10
Filed: 1977-12-29
Abstract: PURPOSE:To prevent output, drivability and fuel consumption from being worsened, by making an increase of advance angle of the ignition timing as a quantity of EGR increases, with said increase raising a speed of combustion. CONSTITUTION:For the throttle valve when fully closed and slightly opened, an EGR valve 7, vacuum advance angle device 16, control valves 29, 36 are not operated with an operation of EGR not made, and an angle advancement of the ignition timing is also not operated. By an increase of the load, with the throttle valve made opening to above a prescribed degree of opening, a negative pressure, applied to a negative pressure chamber 10, goes lower with a quantity of EGR controlled to a small amount. On the other hand, though a degree of angle advancement is small, a less quantity of EGR makes a degree of advancement angle most suitable for the condition. When becoming a time of speed acceleration or high load operation, an exhaust pressure goes higher with both of the control valves 29, 36 operated together. A negative pressure, working on the negative pressure chamber 10, goes higher with a big quantity of EGR operated. And with a negative pressure fed to a negative pressure chamber 18, an ignition angle is largely advanced.

Title: Counting device
Inventor: YAHAGI MITSUTOSHI
IPC: G06M3/00
Filed: 1978-12-27
Abstract: PURPOSE:To confirm the approximate value of a counted value by a counting device without seeing a display unit by counting at every operation of a switch and generating a confirming sound different depending upon the counted value. CONSTITUTION:A switch S1 is operated to display a counting mode, and a switch S2 is operated then to set a counting enable state. Thus, a counter 12 counts at every operation of a count switch S3. Since the counted value in the counter 12 does not initially reach the specified value in the memory 16, a counting sound generator 18a is driven at every operation of the switch S3 to generate a counted sound A by a generator 20. When the counting is advanced to cause the counted value to become the specified value stored in the memory 16, a coincidence signal 17 is applied to a flip-flop 15 at its set terminal. Then, a counting sound generator 18b is driven to thereby generate a counted sound B.

Title: Data collector
Inventor: ISHIKAWA HIROYUKI
IPC: G06Q99/00
Filed: 1980-11-19
Abstract: PURPOSE:To facilitate the decipherment of output data and to shorten data collection time by storing numeric data from a terminal equipment, by storing the character code of this data previously, and by reading a corresponding character when the data is outputted. CONSTITUTION:Each terminal equipment receives a data transfer request from a data collector and then transmits numeric data except character data. When the data transfer is normal, the data is stored in a memory 7 by being classified, and this operation regarding every terminal is repeated until the data transfer ends. Then, a character code which corresponds to a classification code in the memory 7 is retrieved in a file read out of an auxiliary storage device 11 and if it is not found, retrieval is done in a next file. The retrieved character code and each corresponding numeric data are transferred to a printing buffer PB to be printed out. This is performed about all totalization data in the memory 7. Thus, the need for character code transfer which takes a long time is eliminated and the discrimination of an output document is facilitated by character print.

Filed: 1983-09-01
Abstract: PURPOSE:To reduce the number of parts of a detector and make the detection precision higher to facilitate adjustment by using the detector consisting of a potentiometer and a comparing circuit which generates a detection signal of the origin and upper and lower limits of a movable member. CONSTITUTION:When a movable member 11 is turned from the lower limit to the upper limit, a movable contact 35 of a potentiometer 33 is slided on a resistance body 34, and an output voltage E of a comparing circuit 39 is increased linearly in accordance with the increase of the operating angle of the member 11. When this voltage E becomes higher than a reference potential Ed of a comparing circuit 54, a lower limit detection signal is obtained from a comparing circuit part 42 for lower limit detection. When the voltage E becomes higher than a reference potential Ea of a comparing circuit 43, an origin detection signal is obtained from a comparing circuit part 40 for origin detection. When the voltage E becomes higher than a reference potential Ec of a comparing circuit 53, an upper limit detection signal is obtained from a comparing circuit part 41 for upper limit detection. Consequently, the upper or lower limit detection signal is inputted to a microcomputer 23 when the member 11 exceeds the operating range, and a servo motor 15 is stopped quickly.

Title: Fuel control device for gaseous fuel engine
Inventor: NAKAMURA SHIGEMITSU
IPC: F02M25/08
Filed: 1985-07-23
Abstract: PURPOSE:To enable full automatic operation of a fuel gas compressor, by maintaining the supply pressure of gas for an engine at a constant value while the pressure of a liquefied gas tank is sustained within an allowable range. CONSTITUTION:When the supply amount of gas is lowered in such a condition that an engine is operated with the amount of gas consumption being constant, the pressure of supply gas is lowered so that the deviation value with respect to a set value becomes negative. As a result, an instruction for throttling a fuel gas valve 7 is delivered from an electronic gas burner 13 to a gas valve drive servo-motor 8, and simultaneously, the negative deviation value signal is also delivered to a compressor control device 14 to increase the flow rate of a fuel gas compressor 6. In this arrangement, when the cause of lowering the pressure of supply gas is due to the necessity of holding the minimum pressure of a liquefied gas tank 1, the fuel gas valve 7 alone is throttled, and the amount of supply gas is increased, the deviation value becomes positive, and therefore, the fuel gas valve 7 is opened to increase the amount of fuel gas for the engine, thereby the amount of consumption of auxiliary gas for the engine 4 is increased, accordingly.
