Patent number: 5177375Abstract: A semiconductor integrated circuit device comprising an internal reset circuit generating one shot pulse for resetting an internal circuit upon a power on. In the internal reset circuit, inputted to a two-input NOR gate are an output potential of an inverter inverting a first node coupled to a power supply through a capacitor, and an internal clock signal which level inverts at a predetermined timing after rising to a "H" level upon the power on. Then, the output of the NOR gate is applied to a second node in an internal circuit to be reset. The internal reset circuit outputs one shot pulses synchronizing with the first fall of the internal clock signal after the power on irrespective of a potential change rate of the first node after the power on. The first node is set to more easily attain a "H" level than the second node to be reset to a "L" level at the power on by adjusting characteristics of circuit elements connected to the first node and those of circuit elements connected to the second node.Type: GrantFiled: December 14, 1990Date of Patent: January 5, 1993Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Toshiyuki Ogawa, Shinji Kawai

Patent number: 5095555Abstract: A toilet seat has a heater connected to a controller for supplying heating current thereto via a first cable. A thermo-sensor in the toilet seat provides temperature signals to the controller via a second cable. The controller terminates the current to the heater upon the termination of signals from the thermo-sensor. The wires of the second cable have a diameter larger than those of the first cable, so that the wires of the second cable, which provide the temperature signal to the controller, will fail due to bending stresses upon repeated raising and lowering of the toilet seat, before the wires of the first cable. This will cause the controller to terminate the supply of current to the heater.Type: GrantFiled: May 25, 1990Date of Patent: March 17, 1992Assignee: Aisin Seiki Kabushiki KaishaInventors: Yoshiyuki Torii, Yuji Yamaguchi, Shinji Kawai, Kenichi Kaneko

Patent number: 5084917Abstract: A lavatory seat device includes lavatory seat accommodating a heater and a thermo-sensor for detecting a temperature thereof. First lead wires supply an electric current to the heater. Second lead wires convey a signal from the thermo-sensor. A control circuit controls the heater in response to the thermo-sensor in such a manner that the current supply of the heater is interrupted when the signal from the thermo-sensor becomes a set value or the cutting of the second lead wires is detected. A case has the control circuit therein. A first pivot portion of the lavatory seat has a hole through which the first and second lead wires extend. A second pivot portion of the case is fitting with the first pivot portion to pivot the lavatory seat. A holder holds the first and second lead wires in such a manner that the cutting of the first lead cannot occur prior to the cutting of the second lead wire.Type: GrantFiled: November 26, 1990Date of Patent: February 4, 1992Assignee: Aisin Seiki Kabushiki KaishaInventors: Osamu Matsubara, Kenichi Kaneko, Shinji Kawai
