Title: Protective circuit for pulse generator
Inventor: MIYAZAKI TETSUO
IPC: H03K3/57
Filed: 1991-12-09
Abstract: PURPOSE:To obtain a protective circuit which performs protective processing correctly even when a pulse period is shortened as the protective circuit for a pulse generator which performs protection so as not to include a pulse with excessive pulse width in an outputted pulse train. CONSTITUTION:An electric charge charged in a capacitor 8 in a period where the pulse exists is discharged via a resistor 9 with low resistance value and a transistor 13 in the period where no pulse exists. When the potential of the capacitor 8 exceeds a prescribed value and a thyristor 4 is energized, a fuse 2 for protection is cut. Thereby, connection between a switching circuit 3 and a power source 1 is disconnected, and no pulse can be outputted.

Title: Water pressure measuring device for water feeding system
Inventor: WATANABE HISAYASU
IPC: G05D7/06
Filed: 1993-12-28
Abstract: PURPOSE:To finely control water feeding based on the water feeding pressure without a pressure sensor by measuring the water pressure based on the calculation of the ratio of the change in water volume accompanied with opening control for water- volume control valve to the duty ratio calculation value required therefor. CONSTITUTION:A microcomputer sets the water volume flowing in a distributing pipe, determines a duty ratio based on the deviation between a detected water volume and set water volume, and controls supply voltage for a motor 56 by means of control pulse for the ratio. Thus, the detected water volume is made equal to the set water volume. In this case, the shift of a valve body of a water-volume control valve 50 is influenced by the water pressure applied to a valve port 53, that is, the supplied water pressure helps the body 52 be shifted while the body 52 is to be shifted to the opening direction, and, on the contrary, it becomes resistant when the body 52 is to be shifted to the closing direction. The influence of the supplied water pressure appears as a difference of duty ratio calculation value in a process where the water volume is changed. Therefore, a microcomputer calculates the ratio of the changes in water volume to the duty ratio calculation value required therefor so as measure the supplied water pressure.
