Title: Supercharge pressure controller of engine with supercharger
Inventor: NOSE HIROSHI
IPC: F02B39/16
Filed: 1989-08-25
Abstract: PURPOSE:To prevent damage of an engine or an exhaust system by providing a means which decreases supercharge pressure control in the vicinity of an operation condition at he time of an over supercharging condition. CONSTITUTION:A control unit 15 receives output signals on the engine operation of an engine from a throttle opening sensor 25, an atmospheric pressure sensor 26, an engine speed sensor 27, a travel distance sensor 28, a supercharge pressure sensor 29 and the like to calculate target supercharge pressure and detect real supercharge pressure through the the sensor 29 so as to feed back the real supercharge pressure such that it may become the target supercharge pressure. Under fuel injection control by the unit 15, when the real supercharge pressure is more than a limited supercharge pressure, primary and secondary fuel injection valves 10, 11 are closed so as to cut the fuel injection. It is judged whether the cutting is performed or not. In the case that fuel cut is performed, base duty is lowered only by a specified value based thereon so as to decrease supercharge pressure control. Consequently, the fuel cut is prevented from being repeated intermittently.

Title: Pyroelectric element
Inventor: TANIGUCHI SHINICHI
IPC: H01G7/04
Filed: 1987-09-01
Abstract: PURPOSE:To suppress a noise level below conventional 40% and to to obtain the pyroelectric element with high reliability by polarizing only a sensing electrode part. CONSTITUTION:A thin plate 2 which is not polarized is provided with sensing electrodes S-1 and S-2 and only the electrode parts are polarized. In general, when the polarization processing is performed, secondary operation such as piezoelectric operation is caused by a part which does not require a pyroelectric function and the pyroelectric element is stressed owing to a difference in heat expansion among materials as the temperature varies, thereby generating a noise. The noise is generated with width W and length L at the time of conventional polarization processing, but the piezoelectric secondary operation is only a+a and E when only the sensing electrode parts are polarized; and the noise level ratio under the same conditions is suppressed below about 40%, so that the highly reliable pyroelectric element is obtained.

Title: Clock circuit
Inventor: SAITO MIKIO
IPC: G04G3/02
Filed: 1990-08-23
Abstract: PURPOSE:To obtain a highly versatile IC by providing an oscillation circuit which consists of an inversion mans which inverts input signal and a means for feeding back output of the inversion means. CONSTITUTION:A 32.768 kHz oscillation element is connected between terminals 1 and 2. Then, a control signal 6 for selecting whether a commercial power supply or the 32.768 kHz oscillation element is used as a signal source is set to a low level. In this case, an AND gate 8 always outputs the low level, thus enabling a clear signal 26 to be at a low level, preventing a 2<11> dividing circuit 11 from being cleared, and an input signal 27 to be divided in sequence. An oscillation circuit 3 outputs a 32.768 kHz signal based on the 32.768 kHz oscillation signal at the terminal 1. Since the clear signal 26 is at the low level, the 2<14> dividing circuit 11 allows output of the oscillation circuit 3 to be divided and an output signal 5 which is divided (2<14>) to be output. Also, since the control signal 6 is at the low level, a selection control circuit 7 selects the output signal 5 out of output of a counter circuit 4 and outputs it, thus enabling signal obtained by dividing 32.768 kHz signal (2<14>) to be output and obtaining a signal with 0.5 second per cycle for achieving clock operation.
