Title: Semiconductor device
Inventor: TADA KAZUHIRO
IPC: H01L27/06
Filed: 1988-01-14
Abstract: PURPOSE:To control the maximum value of the power supply voltage in accordance with the dielectric strength characteristics of an internal circuit to ensure said dielectric strength characteristics and to improve the yield of a semiconductor device by controlling the power supply voltage supplied to the internal circuit with an external signal to avoid such a case where said power supply voltage is kept under a prescribed voltage level. CONSTITUTION:The prescribed voltage is applied to one of control terminals T1-T3 via a selection circuit 1 by the combination of external control signals phi1 and phi2. Thus one of transistors TRQ8-Q10 is turned on. As a result, the synthesized threshold voltage of the TRQ1-Q8 connected in series is reduced so that the power supply voltage is kept under a prescribed level. Therefore a burn-in test, etc., are carried out with the voltage of a high level with the turning off all TRQ1-Q8, and with no voltage applied to both signals phi1 and phi2. In a normal application state, the maximum value of the power supply voltage is controlled in accordance with the dielectric strength. Thus the dielectric strength is ensured and the yield is improved with a semiconductor device.

Title: Optical scanner
Inventor: MORI TAKAHIRO
IPC: G02B26/10
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To stabilize the scanning action of an optical scanner constituted so that a mirror is rocked by transmitting the rotation of a motor to the mirror via a reduction gear train extending over a long term. SOLUTION: The number of teeth constituting the gear of the reduction gear train 27 is set, so that the ratio of the rotating frequency of the pre-stage gear to the rotating frequency of the final-stage gear fixed to the mirror becomes a noninteger number. Then, when the rocking frequency of the mirror reaches at a prescribed value, the mirror is subjected to full rotation. Since the bias of the wear of the pre-stage gear caused when the mirror is rocked is reduced, the play on the train 27 is delayed. Thus, the scanning action is stabilized, extending over a long term.
