Inventor: HASEGAWA TAKAKUNI
IPC: G03B27/73
Filed: 1983-04-25
Abstract: PURPOSE:To shorten the queuing time of charging of a capacitor by stopping the discharge of the capacitor when the intensity of light is damped and reduced to a value which does not contribute to the change of a sensitive material. CONSTITUTION:When the intensity of light of an electronic flash discharge tube 3 is reduced to a value, which does not contribute to the change of a sensitive sheet B, in the damping process after the time when this intensity of light has a maximum value with one discharge, the charging voltage of a main capacitor Cm is reduced to a preliminarily determined prescribed value, and this reduction is detected by a comparator 24.

Title: Semiconductor integrated circuit device
Inventor: YAMAZAKI HIROKAZU
IPC: H03K19/003
Filed: 1990-03-20
Abstract: PURPOSE:To suppress the variation of supply power without damaging the operation speed to prevent the malfunction by keeping the output potential at the intermediate potential of a binary level for a certain time at the time of the change of an input signal and switching the output potential from the intermediate potential to the regular binary level after the certain time. CONSTITUTION:When the input signal is changed, an input signal change detecting circuit 33 outputs an activating signal in the high level for a certain time, and the output potential of an output circuit 34 is slowly changed to the intermediate potential of the binary level and is kept at this potential in response to this activating signal by an output signal change detecting circuit 35. The output potential is switched from the intermediate potential to the regular binary level potential based on the operation result of a logic circuit 32 after the certain time. That is, the change of the output voltage is considerably smaller than normal that because of the change from the intermediate potential, and the discharging current is minimized. Thus, the variation of supply power of pads in a chip is suppressed without damaging the operation speed to prevent the malfunction.

IPC: G01C3/06
Filed: 1991-03-11
Abstract: PURPOSE:To prevent error detection due to the reflection by rain drops by so constituting that the level of sensititvity time control (STC) circuit varies when raindrops are detected by a raindrop sensor and the like. CONSTITUTION:When raindrops are detected by the actuation of a raindrops sensor or a wiper switch, the level of an STC circuit 31 varies. And the level of the circuit 31 is so set as to become larger then the case the detected reflection by raindrops is received and the level of the circuit 31 increases with the amount of rain drops and the like. Thus, through the comparison at a comparator 19, the level in the case reflection by raindrops is received, is judged smaller than the level of the circuit 31 and the comparator 19 does not output a pluse signal and therefore, error detection by the reflection by raindrops and the like is prevented.
