Title: Branching device for railroad
Inventor: OKADA KATSUYA
IPC: E01B25/28
Filed: 1992-12-11
Abstract: PURPOSE:To smoothly move a moving beam by laterally moving a moving beam with each connecting pin to connect a plurality of moving beams held through a pin receiver on a truck, and making the connecting pin sliclable in the pin receiver in the longitudinal direction of the moving beam. CONSTITUTION:In the case where a branch start C is track-shifted between a reference position A. and a branch position B, lateral moving force is acted on each of trucks 4 by a hydraulic cylinder or the like. The lateral moving force is simultaneously transmitted to two adjacent moving beams in the connecting part of each of moving beams C1 to C4 through a pin receiver 11, a roller 9 and a connecting pin 1, and each of moving beams C1 to C4 is thereby laterally moved together with the truck 4. Since in this case, the pin receiver 11 moves in one body with the truck 4, and on the other hand the connecting pin 1 moves curvedly, moving force is transmitted as the pin receiver 11 and the connecting pin 1 move in the longitudinal direction of a track C. In addition frictional resistance occurring when the roller 9 moves to the pin receiver 11 decreases. Thus a moving force transmitting mechanism can be used in common between the adjacent beams, and the damage of a connecting part can be sharply reduced.

Abstract: PROBLEM TO BE SOLVED: To reduce a forward voltage such that a forward current starts flowing and reduce a reverse voltage, by commonly connecting a gate electrode with a first wiring metal layer to form an anode terminal and causing a second wiring metal layer to be a cathode terminal. SOLUTION: By applying a voltage so that an anode terminal 10 is positively charged and a cathode terminal 11 is negatively charged, a channel is formed on the interface of a second semiconductor region 4 with a gate insulating film 6. As a result, a current path is formed from a first semiconductor region 3 via the channel to a third semiconductor region 5. Conditions for forming the channel are adjustable by physical constants, such as, the density of impurity in the second semiconductor region 4, the thickness of the gate insulating film 6, and the type of a gate electrode 8. The constants may be so selected that the channel is formed at a forward voltage between anode and cathode being not lower than 0V. If a lower voltage is applied to the anode terminal 10 than the voltage applied to the cathode terminal 11, no channel is formed in the second semiconductor region 4.
