Abstract: PURPOSE:To prevent degradation in the performance of an engine due to misfiring or the like, by providing a means for judging operational conditions of the engine and a control switching means for switching the mode of control from theoretical air-fuel ratio control to air-fuel ratio control for obtaining optimum specific fuel consumption. CONSTITUTION:An electronic control unit 8 controls the quantity of fuel on the basis of output signals from an air-flow sensor 2, a turning-angle sensor 7, a throttle sensor 10, a water-temperature sensor 11 and an air-temperature sensor 12. In case that the water temperature detected by the water-temperature sensor 11 is lower than a prescribed value, warm-up control is executed. In case that the water temperature is higher than the prescribed value, on the other hand, judgement is made on whether a timer has passed 15min or not. In case that 15min is not yet passed, air-fuel ratio control for obtaining optimum specific fuel consumption is executed. After passing of 15min, the mode of control is switched to theoretical air-fuel ratio control. By employing such a method, it is enabled to obtain excellent performance of an engine while keeping low fuel consumption.

Title: Life deterioration notifying device for car battery
Inventor: HATAKEYAMA YOSHINARI
IPC: G01R31/36
Filed: 1988-03-11
Abstract: PURPOSE:To give warning about deterioration of the battery life when the mean temp. tends to rise and the inter-cell temp. difference has exceeded the standard value by sensing difference between the internal temp. of the engine room and the mean temp. of battery electrolyte and also the temp. difference between battery cells. CONSTITUTION:After an engine is started, the electrolyte temp. of a plurality of cells of a battery and the interval temp. of the engine room are monitored always by,a group of thermo-sensors 3. As the heat capacity of the battery is large, the rise of the battery temp. delays to the rise of the internal temp. of engine room after the engine is started. A battery with progressed life deterioration, however, involves internal temp. running due to internal shortcircuiting and element deterioration, which raises the mean temp. Eventual deterioration of any specific cell enlarges the temp. difference between the cells. These temps. are passed through a temp. sensor circuit 4 to a comparative computing circuit 5. Which compares them with the standard temp. difference given by a standard temp. difference setting circuit 6, and if at a high temp. a warning is given from a warning indicator 7.

Abstract: PURPOSE:To facilitate the switching jobs and to decrease the number of component parts together with reduction of the cost by projecting the protruding piece of a wall hook interlocking the chin notch of a telephone receiver over the recess part for the receiver with a wall hang type handset. CONSTITUTION:When a telephone set is put on a desk, a telephone receiver recess part 6 is turned upward and a telephone receiver 4 is put into the part 6. Then a handset 3 is hooked to a telephone main body 2 and never slip down. In this case, a pivot 41 is moved to one of both end parts of a pivot support hole 51 so that the handset 3 can be smoothly picked up. While the pivot 41 is moved to the other end part of the hole 51 when the handset 3 hanged on a wall. Thus a protruding piece 42 of a wall hook 40 projects over a window 6A of the part 6 and a chin notch 4A of the receiver 4 of the handset 3 interlocks the piece 42. Therefore the handset 3 never slips down the main body 2. Thus it is possible to decrease the number of component parts and also to facilitate the switching jobs together with reduction of the cost.

Title: Serial printer with detecting function for paper jamming
Inventor: MIZUNO ATSUSHI
IPC: B41J13/00
Filed: 1988-03-12
Abstract: PURPOSE:To prevent troubles from occurring due to paper jamming, by measuring time after the starting of a driving motor for a head and a recording paper by a timer, and detecting as a paper jamming the condition where the timer shows the lapse of a prescribed time required for both printing a one-line amount of data and feeding the paper. CONSTITUTION:A timer runout discriminating means 58 judges whether a prescribed time required for both printing a one-line amount of data and feeding a recording paper has passed, based on the time measured by a timer 54 after the starting of a driving motor 12 for a head and the paper. Normally, when the lapse of time after the starting reaches the prescribed time, the motor 12 is stopped by an operation of a home switch. When paper jamming occurs, however, the motor 12 is not rotated smoothly, and is eventually stopped, so that the prescribed time passes. When runout of the timer 54 occurs, a timer runout signal generating means 60 turns OFF the motor 12 through the discriminating means 58, and displays the condition on a paper jamming display device 52. A timer-resetting means 56 resets the timer 54 when the motor 12 is turned OFF by the home switch. Thus, it is possible to prevent troubles from occurring due to paper jamming.

Title: Voltage converter type monostable multivibrator
Inventor: HAMURA YOSHIHIRO
IPC: H03K3/023
Filed: 1978-05-18
Abstract: PURPOSE:To obtain the stable output even to the temperature fluctuation by forming the monostable multivibrator with the level clamper consisting of diode D and transistor Tr, the charge/discharge circuit of the shift circuit and the capacitor and the differential amplifier. CONSTITUTION:The voltage converting monostable multivibrator is constituted with the level-shift circuit consisting of input level clamping diodes D1-D3, Tr1 and Tr2 plus D4-D6, the charge/discharge circuit of capacitor C, the differential amplifier comprising Tr5 and 6, temperature compensating diode D7 and D8, and Tr3 and Tr4 of the constant current source. With application of the H-level signal to terminal 4, capacitor C is charged via Tr1, D4-D6 and Tr2 each. When the signal features the L level, potential Vx of point A lowers following the discharge slope of C. Even if Vx fluctuates by the temperature change, potential Vz of point B varies due to D7 and D8 to offset the fluctuation of Vx. And the voltage slope of Vx does not change in case the input signals features the L level regardless of the temperature change. Accordingly, the intersection (Fig. b) between Vx and Vz does not change, and period Ts of the high level is constant for the signal applied to output terminal 5.
