Title: Semiconductor device
Inventor: WATANABE SHIGEYOSHI
IPC: H01L29/78
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To reduce gate leakage current dependent on the intensity of an applied electric field by reducing the maximum voltage applied to a gate insulating film when LSI using a microminiature transistor is in standby state, as compared with in active state or connecting an additional element. SOLUTION: A gate leakage current is expressed as an exponential function of the intensity of an electric field applied to the gate insulating film of a MOS transistor, and the leakage current of LSI in standby state can be significantly reduced. That is, to set Vcc* to a potential at which any problem associated with gate leakage current is not posed, an at-standby reference supply potential generating circuit obtained by series-connecting a MOS transistor 1 and a resistor 1 between a power supply node B and a ground potential is used. When a gate leakage current flows to the MOS transistor 1, node A is raised and feedback is performed by a differential amplifier 1 so that node B is lowered. By adjusting the voltage of Vref1 in advance, the node is ultimately reduced to an internal supply voltage free from gate leakage current.

IPC: H04B1/26
Filed: 1992-04-14
Abstract: PURPOSE:To improve the detection sensitivity by repeating the high-sensitive mode long in operating period with large synchronization and the low-sensitive mode short in operating period with small synchronization in the operating period of a super heterodyne receiver which operates intermittently. CONSTITUTION:A timing controller 31 starts a 50msec timer 32.

Title: Time switch
Inventor: MATSUDA MASANORI
IPC: H01H43/02
Filed: 1989-04-15
Abstract: PURPOSE:To confirm electrical feeding to a driving source and the operation of a switch element with visual observation by providing a first display element for emitting the light at the time of electrical feeding to the driving source and a second display element for emitting the light at the time of operating a switch element, and setting the first display element and the second display element to have different light emitting colors. CONSTITUTION:A light emitting diode LD1 functions as a first display element for emitting the light at the time of electrical feeding to a motor M as a driving source. A light emitting diode LD2 functions as a second display element for emitting the light at the time of operating a switch element which consists of a relay Ry. Since the first display element LD1 emits the light with electrical feeding to the driving source, the electrical feeding condition to the driving source can be observed visually. Furthermore, since the second display element LD2 emits the light when the switch element is operated, the first display element and the second display element emit the light simultaneously. However, since both the light emitting elements are housed in one package and are also set to have different colors, color mixture can be obtained under the condition that both the light emitting elements emit the light simultaneously. consequently, electrical feeding to the driving source and the operation of the switch element can be identified with visual observation.
