IPC: H03M1/82
Filed: 1987-04-10
Abstract: PURPOSE:To attain high speed and high accuracy D/A (digital-analog) conversion by detecting a delay time of a logic element as delay elements connected in series while counting number of logic element stages in one sampling period. CONSTITUTION:A sampling timing signal (s) is delayed by logic elements 8 connected in series and a holding device 9 comprising a D flip-flop holds the output of logic elements 8, that is, the internal momentary state of the logic elements 8 synchronously with the signal (s). A counter 10 discriminates that at how many stages from the initial stage of the elements 8 the internal state changes from 1 to 0 and outputs the count output (c). That is, the delay corresponding to one sample period is obtained by using the logic elements 8 having the same number of stages as the count output (c). The selector 13 is controlled by the output of the multiplier 12 multiplying the count output (c) with the input digital value (d) to select any of plural stages of logic elements 8. Thus, the D/A conversion with high speed and high accurate pulse width modulation form is attained.

Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a means capable of promoting warming up of an engine or rising of temperature of an exhaust emission purifying catalyst, while suppressing a torque change within a permissible range, even in the case of interruptedly executing roughness control. SOLUTION: In an engine system A, ignition timing of a spark plug 7 is markedly delayed when an engine 1 is cold started, and in this way, its warming up and a temperature rise of catalytic converter rhodium in a catalytic converter 27 are promoted. Roughness control is performed by an ECU35, a torque change (roughness) caused by a marked delay timing of the ignition timing is suppressed, and the torque change can be controlled within a permissible range. Here, a roughness control amount just before stopping is held when the roughness control is temporarily stopped. Hereafter, the held roughness control amount is used when the roughness control is restarted, and in this way, stability or responsibility of the roughness control is enhanced.

Abstract: PURPOSE:To uniformly clamp a layer-built type fuel cell body to always keep a surface pressure value constant, and to obtain stable output of a cell by disposing a plurality of springs within the surfaces of a pushing upper plate and a pushing lower plate. CONSTITUTION:A plurality of springs 11 are disposed between plate members 9a, 9b and between plate members 10a, 10b, and the springs 11 is positioned by a strut 12. The body of a layer-built type fuel cell operates by pressing the whole plane to a fixed surface pressure value after the completion of laminating and assembling. For this reason, a plurality of springs 11 are evenly contracted by a pushing upper plate 9 which accommodates the springs 11 and the strut 12, a pushing lower plate 10 and a pushing rod 4 when a pressing force is applied to the body 1. The distribution of surface pressure becomes uniform if the spring constant is selected to make the variation of the pressing force of the springs 11 small, even if the plate members 9a, 10a are deformed as shown by broken lines. Further, it is possible to always hold the surface pressure value constant by absorbing the expansion and the contraction due to the thermal expansion of the body 1 and an insulating plate 2 and the pushing rod 4 by means of the springs 11.

Abstract: PURPOSE:To save an energy and to make an apparatus small in size by a constitution wherein hot water is connected to a hot water supply circuit including a heating circuit and a hot-water tank via a header so that the hot water at a temperature below a prescribed level is discharged and that the hot water is supplied when the quantity of reserved hot water exceeds a prescribed level. CONSTITUTION:Hot water is supplied to a header 15 through a supply pipe 11. In heating, valves 22 and 25 are opened and a pump 24 is driven to circulate the hot water through a radiator 23. When the temperature 36 of the hot water falls at this time, a solenoid valve 35 is opened and the hot water is supplied to a hot-water tank 32 and reserved therein so as to be used for hot-water supply other than drinking. When heating is unnecessary, the pump 24 is stopped, the valves 22 and 25 are closed, and thereby the hot water is reserved in the tank 32. The quantity of hot water reserved in the tank 32 is detected by a level relay 37 and the solenoid valve 35 is closed according to the detection. By converging pipelines 20 and 30 for heating and hot-water supply into the header 15 in this way and by making the header 15 function as a heat-accumulating tank which adjusts the pressure and flow rate of the hot water and changing the volume thereof according to a load, an energy can be saved and an apparatus can be made small in size.
