Title: Oscillation circuit
Inventor: KATAYAMA TOMOYUKI
IPC: H03B5/32
Filed: 1987-02-18
Abstract: PURPOSE:To reduce the time till the oscillation is made stable from the oscillation start by connecting a bias circuit generating a prescribed bias voltage at the operation stop of an inverter circuit for oscillation to an output terminal or an input terminal of the oscillation inverter circuit. CONSTITUTION:While the oscillation circuit stops its oscillation, a P-channel transistor (TR) 52 and an N-channel TR 53 are turned on and an inverter circuit 50 is in the operating state. Thus, the potential at the output terminal C is kept to a prescribed middle level M depending on an input/output voltage (VIN- VOUT) characteristic of the inverter circuit 50 and a load characteristic. Thus, TRs 32, 33 constitution the oscillation inverter circuit 3 are turned on in the oscillation circuit at the start of oscillation when the control signal A changes from a low level to a high level and the oscillation is started from the middle level immediately. As a result, the time T' till the stable oscillating state is drastically reduced.

Filed: 1995-02-22
Abstract: PURPOSE: To prevent abraded powder from adhering to an exposed face of a wheel by covering the exposed face, which is exposed when a tire is mounted, of a wheel for a vehicle by means of a resin film made of fluororesin or silicone resin. CONSTITUTION: A wheel 10 is desirably made of aluminum alloy in respect of processability, an appearance, and reduction in weight, though it may be made of an optional material. A resin film made of fluororesin or silicone resin must be formed on an exposed face, which is exposed when a tire is mounted, in the wheel.
