Filed: 1990-05-30
Abstract: PURPOSE:To speed up the optical element which utilizes a change in refractive index by providing grooves of a specific width in the part where the carriers of a semiconductor are excited or near this part. CONSTITUTION:The grooves 75 having lambda0/(4n) width in the part where the carriers of the semiconductor are excited or near this part, lambda0 is the light wave length in a vacuum; n is the linear refractive index of the semiconductor. Name ly, the response speed of a change in the refractive index of the semiconductor by the actual excitation by the light of electrons is determined by the time (carrier time) when the electrons make recombination. The extremely thin but deep grooves 75 are dug in the optical element down to the part where the electrons are excited in this case. The formed carriers are then recombined in a short period of time by the surface of the formed grooves 75. The response speed is improved in this way.

Title: Movable contact in tap selector
Inventor: SHIMIZU HIROMASA
IPC: H01F29/02
Filed: 1986-06-19
Abstract: PURPOSE:To prevent extrusion force from being applied to rod contacts in the direction of their central lines, by disposing the rod contacts radially against the rotational center of a movable contact part. CONSTITUTION:A plurality of fixed contacts 2 are disposed at regular intervals on the circle and on the same flat plane as a collector ring 1 disposed in the center of a tap selector. A plurality of rod contacts 3 are inserted into the same number of bearings 4 and disposed radially against the rotational center of the tap selector. Force pressing the rod contacts 3 on the collector ring 1 and the fixed contacts 2 is applied to the bearings 4 by using energizing means. A movable contact part 12 is formed to move together with a contact case 11 when the case 11 is driven by means of the driving force in the driving mechanism. Thus in this movable contact part 12, frictional forces applied to the rod contacts 3 at their points in contact with the collector ring 1 and the fixed contact points 2 are operated only in the direction perpendicular to the central lines of the rod contacts 3, that is, in the direction of rotating the rod contacts 3. All the frictional forces occurring at the contact points of the rod contacts 3 in contact with the collector ring and the fixed contact points 2 become the driving forces for rotating the rod contacts 3.
