Title: Semiconductor element
Inventor: SASAKI NOBUO
IPC: H01L27/088
Filed: 1991-03-08
Abstract: PURPOSE:To ensure a 1:1 duty pulse signal by shaping signals produced at a receiver side piezoelectric element with respect to rise and fall edges of an input pulse signal into two pulse signals via a latch circuit, applying 1/2 frequency division to the signals, then outputting the result. CONSTITUTION:Vibration is generated from an ultrasonic wave signal sender side piezoelectric element 1 in response to the rise and fall edges of an inputted pulse signal. The vibration is delivered to an ultrasonic wave receiver side piezoelectric element 2, from which a signal whose rise and fall time correspond respectively is generated. The signal generated in the element 2 is vibrated and includes plural pulses, and each one pulse is obtained at the rise and fall edges by the provision of a latch circuit 3. Then a frequency divider circuit 5 applies 1/2 frequency division to the output of the circuit 3 to obtain one pulse signal at the rise and fall edges. Thus, one pulse signal is obtained with respect to one pulse signal inputted to the element 1.

Abstract: PURPOSE:To prevent insufficient electric charging from occurring when resetting a system and enhance reliability of the system and reducing the rate of fuel consumption, by providing a means for integrating a charging current supplied to a battery and a means for resetting the system from a released condition when the integrated value has reached or exceeded a predetermined value. CONSTITUTION:A timer 40 closes a switch 43 after the elapse of a predetermined period of time from the moment a trigger signal is supplied, whereby a  voltage corresponding to a battery voltage is supplied to an integrator 44. When  the capacity of the battery is insufficient, a large voltage drop occurs, so that  the integrated value does not reach a set point V1. Therefore, a battery-controlling signal 1 is turned OFF, and the system of the automatic stopping and starting device for the engine is released. When the amount of the electric current charged into the battery reaches or exceeds the predetermined value, a system- resetting signal is supplied to a memory circuit 46. Accordingly, insufficient charging and unrequired releasing are prevented from occurring when resetting the system, and the reliability of the system can be enhanced.
