Patent JP-H09223792-A (JP)
Title: Optical breakover diode
Inventor: BERUNTO BIREKOOBUEN
IPC: H01L31/111
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To improve optical sensitivity in a peripheral region capable of irradiation from the side direction, by making a periphery-gate-cathode resistor arranged between an N<-> layer and a peripheral part emitter larger than a central part-gate-cathode resistor arranged between the N<-> layer and an inside emitter. SOLUTION: A peripheral part emitter 5b' in the peripheral region 110 is designed to be thicker than an inside emitter 5b in the central region 120. The sectional area in the lateral direction in the peripheral region in which charge carriers are generated by irradiation 9 from the side direction is made smaller. Large resistance of a gate 4 below the peripheral part emitter 5a' is ensured. Therefore, voltage drop in the case of a specified photoelectric current is increased as compared with the structure where the thick peripheral part emitter 5a' does not exist, and the minimum photoelectric current necessary to reach the ignition condition can be decreased, so that the optical sensitivity in the peripheral region capable of irradiation from the side surface can be increased.

Title: Controller for tractor-drawn scraper
Inventor: ONARI YASUKE
IPC: E02F3/84
Filed: 1991-02-21
Abstract: PURPOSE:To raise the efficiency of excavating operation by a method in which speed sensors are provided for a tractor and a scraper wheel, a slip amount is calculated from the turning speeds of both the tractor and the scraper wheel, and the height of a ball is automatically adjusted to control the amount of excavation without slip. CONSTITUTION:When a tractor is traveled to drag a scraper, measurement is made for every given periods by sensors 8-12 and measured signals (V)EL, (V)ER, (V)SL, and (V)SR and BH from the sensors 8-12 are put in a controller 13. The measured signals BH are compared with an allowable range to confirm that the height of a ball is within allowable range. If it is out of the allowable range, the height of the ball is moved to a preset one, and the difference between the turning speed of the tractor and the turning speed of the wheel of scraper is calculated in the controller 13. When the difference E is in positive value, a judgement that the traveling system of the tractor is slipped is made and a command is given to correct the position of the ball to given height for a ball drive mechanism 14. The height of the ball is adjusted by the drive mechanism 14, and the load from the ground's surface to the ball can be reduced to eliminate slipping.
