Abstract: The present invention provides a semiconductor integrated circuit device in which its internal node can be precharged at a high speed while suppressing current dissipation as in a conventional device by adding a circuit which assists charging when a power supply voltage begins to rise and a method for precharging. The semiconductor integrated circuit device includes a precharge circuit which comprises a first charge circuit, a second charge circuit which is higher in charging speed than the first charge circuit, a charged level detect circuit for detecting the charged level of the internal node when the first charge circuit is being driven, and a charged level stabilization circuit. The precharge circuit may further comprise a charged level control circuit.

Abstract: The semiconductor circuit device comprises a substrate bias generating circuit, a substrate voltage detecting circuit, and a substrate impedance adjusting circuit. When the detected substrate voltage decreases below a predetermined level, the substrate impedance adjusting circuit forms a through route between a substrate voltage terminal and any given terminal higher in potential than the substrate voltage terminal, to increase the substrate voltage at high speed, thus stabilizing threshold voltages or operation limit voltages of device elements which are subjected to the influence of the substrate voltage. Further, when the substrate voltage returns to the predetermined level, the substrate impedance adjusting circuit cuts off the formed through route for reduction of power consumption.

Abstract: A precharge circuit is provided with a step-up node circuit including a capacitor for delivering a drive voltage at a predetermined level to a load, and for raising the voltage level of the drive voltage so that it becomes equal to a value greater than the predetermined level by a specific value. This precharge circuit at least comprises a main P-channel MOS transistor for delivering the drive voltage at the predetermined level to the load through the step-up node circuit when a step-up input signal delivered to the step up node circuit is at a ground level, and a subsidiary P-channel MOS transistor for interrupting supply of the step-up input signal immediately before the drive voltage is raised to the predetermined level by the step-up input signal. Accordingly this precharge circuit normally operates immediately after being powered. Thus, initialization becomes unnecessary.

Abstract: An annular support of a clutch disc made of a plate member having connecting apertures and radial slits. Friction material facings are die pressed into engagement with the plate member with dies which force the friction material through the apertures and slits to integrally connect the facings to the plate member and to each other. Each facing is provided at its surface with hollows positioned over the slits and having circumferential widths wider than the slits. The hollows overlap the edge portions of the slits at the opposite sides of the slits. The hollows in the facings are formed by projections on the faces of the dies in the forming operation.
