Abstract: A controlling circuit of the voltage monitoring circuit turns on a first positive-side switch and a first negative-side switch, turns off a second positive-side switch and a second negative-side switch, and sets a switch circuit in a first connection state, and after that, the controlling circuit turns off the first positive-side switch and the first negative-side switch, and after that, the controlling circuit sets the switch circuit in a second connection state.

Abstract: A semiconductor integrated circuit includes a first constant current output circuit that outputs a first constant current from a first constant current terminal to a first output terminal. The semiconductor integrated circuit includes an error current output circuit that outputs an error current from an error current terminal to the first output terminal.

Abstract: A gamma-correction circuit, comprising a gamma-reference voltage generation circuit capable of outputting voltages from connection nodes between a plurality of first resistor units connected in cascade, a gamma-correction voltage generation circuit configured to output gray level voltages from connection nodes between a plurality of second resistor units connected in cascade, the second resistor units having the same circuit configuration as the gamma-reference voltage generation circuit and having the same resistance ratio as that of the plurality of first resistor units, and at least one buffer connected between at least one connection node of the gamma-reference voltage and the corresponding connection node of the gamma-correction voltage.

Abstract: A thermostat has a switch, a temperature sensor, a lever, a spring, and a control plate. The sensor generates a force to operate switch in response to the ambient temperature. The lever having an arm turns with the force from the sensor to open/close contacts of the switch. The first end of the spring is hooked to the lever to bias a force to the lever in the direction opposite to the force from the sensor. The control plate is hooked to the second end of the spring and is disposed on the lever, allowing a force for turning the lever to increase or to decrease due to turning of the control plate. The control plate turns the arm to perform the forced switch-off operation.

Abstract: A thermostat includes a wall plate unitarily molded of thermoplastic resin, a first metal plate holding a temperature sensing section, and a second metal plate holding a cam shaft. A fulcrum of a lever and a fulcrum of adjusting plate are protected by the wall plate and they are not exposed to the outside. Since both the fulcrums are not exposed to the outside, the fulcrums are free from being touched with foreign matters. This thermostat thus prevents a temperature set therein from changing.
