Title: Laser light scanning device
Inventor: SHIMADA KUNIHIKO
IPC: G02B26/10
Filed: 1991-07-31
Abstract: PURPOSE:To increase the deflection angle of laser light and to reduce the size of the device by arranging a magnifying lens on the optical axis of deflected laser light. CONSTITUTION:The device which scans a screen 21 with the laser light has a solid-state element deflector 22 which deflects the laser light and is provided with the magnifying lens 23 which is arranged on the optical axis of the deflected laser light and increases the deflection angle of the laser light. Namely, a cylindrical concave lens 23 is arranged between the screen 21 and solid-state element deflector 22 while having its center axis oriented at right angles to the scanning direction. Therefore, the cylindrical concave lens 23 refracts the laser light in a lateral screen direction to increase the touching angle, so the screen can be scanned to longitudinal width and lateral width which are enough for the screen constitution. Further, a concavely sectioned lens is usable as the magnifying lens 23.

Title: Commutation failure detector
Inventor: AKAO YOSHIZO
IPC: H02M7/219
Filed: 1990-07-23
Abstract: PURPOSE:To obtain a commutation failure detector of a voltage-type inverter in which a gate-turn-off thyristor(GTO) is employed at a low cost and with a reduced size by a method wherein a voltage detector which detects whether a negative bias voltage is higher than a predetermined value or lower than that and an on-delay circuit are provided between G and K of the GTO. CONSTITUTION:As outputs of on-delay circuits 21U and 21X do not overlap each other when a commutation failure does not occur, the output of an AND circuit 22A is logic 0. If a GTO 5U of an upper arm is turned on by some reason, as a GTO 5X of a lower arm is already in an on-state, the commutation failure state is created. If the GTO 5U is turned on, the output of the on-delay circuits 21U is turned from logic 0 to logic 1. As the output of the on-delay circuit 21X is already logic 1, the output of the And circuit 22A is immediately turned from logic 0 to logic 1 when the output of the on-delay circuit 21U is turned to logic 1 and the commutation failure can be detected. As the commutation failure detector has such a simple structure composed of electronic circuits only, the commutation failure detector can be obtained at a low cost and with a reduced size.
