Title: Energizing member and bearing
Inventor: WAKABAYASHI TATSUO
IPC: F16C41/00
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To provide an energizing member and a bearing capable of inhibiting a generation of an abrasion powder and reducing a rotation resistance while ensuring sufficient energizing function. SOLUTION: When a rotating shaft 2 is rotated relative to a fixed portion 1, an energizing ring 4 rolls along circumferential grooves 1b, 2a and the fixed portion 1 and the rotating shaft 2 are energizably connected. Therefore, a rotation resistance can be inhibited more less in comparison with a slide member, such as a wire member while ensuring energizing function. Since the energizing ring has a slide portion, a generation of an abrasion powder can be inhibited to the utmost. Accordingly, when such an energizing ring is provided on a bearing, the generation of abrasion powder causing an early abrasion of the bearing by infiltrating into the gap between a rolling body and a track path can be inhibited to the utmost. Thereby, the service life of the bearing 3 can be enhanced.

IPC: G02B5/20
Filed: 1983-03-01
Abstract: PURPOSE:To suppress the reduction of an opening ratio from the front and to remove color shifting and outline fading phenomena by arranging black light shielding walls along the border lines of respective color areas of a color filter so as to be projected from the surface of the color filter. CONSTITUTION:The black light shielding walls 9 with fixed width and height are arranged on the borders of respective areas 10a-10d of the color filter 10 having the color area 10a-10d such as red, blue, green and yellow. The color filter 10' (10) is arranged in accordance with respective liquid crystal areas 6a-6e of a liquid crystal panel 6. If an electric field is applied only to a liquid crystal area 6c to obtain a light emitting property and an observer 7 observes from the diagonal direction, the adjacent color area 10b' is not observed bacause of interruption by the black light shielding wall 9 and only the color area 10c' corresponding to the light crystal area 6c can be observed, so that color shifting and outline fading phenomena are removed. Since the light shielding walls 9 are projected to the front of the surface, the width of the walls 9 can be reduced and the opening ratio of the front is reduced.

Abstract: PURPOSE:To grow a crystal defect in a short time by repeating heat treatment  at the predetermined speed of a temperature rise corresponding to the oxygen concentration of a substrate as a substrate treating process. CONSTITUTION:The silicon substrate, oxygen concentration thereof is 1.5X10<13> cm<-3> or higher, is thermally treated at the speed of the temperature rise at the rate of 5-14 deg.C/min., and once or more heat treatment is repeated at the speed of the temperature rise at the rate of 14 deg.C/min. or lower. The silicon substrate, oxygen concentration thereof is 1.5X10<13>cm<-3> or lower, is thermally treated at the speed of the temperature rise at the rate of 5 deg.C/min. or lower, and once or more heat treatment is repeated at the speed of the temperature rise at the rate of 14 deg.C/min. or lower. A low temperature as much as possible is preferable as low temperature value where the temperature rise is started, and a temperature such as 500-900 deg.C can apply. The defect grows with the higher setting of the maximum temperature, but the setting of approximately 950-1,300 deg.C is preferable because too high setting often extinguishes the defect.

Abstract: PURPOSE:To simplify the constitution and to attain erasion over the entire surface of a recording medium easily and in a large quantity of information, by applying conductive paste onto the surface of the recording medium to form a conductive film and applying voltage to said conductive film. CONSTITUTION:A recording medium 106 is produced by forming the 1st insulated film 103 on a semiconductor layer 104 such as a silicon single crystal substrate. Furthermore the 2nd insulated film 102 is formed on the film 103 and a conductive layer 105 is coated when necessary to the rear side of the layer 104. In this case, recording is applied to the medium 106 and the electric charge is stored in the film 102 according to the record signal. The layer 104 uses then type silicon to perform recording with positive voltage to obtain electrons 107 as shown in the figure. A conductive layer 101 is applied onto the surface of the medium 106 for erasion, and the voltage (negative voltage 108) of the polarity opposite to that of a recording mode is applied to the film 101. Thus the erasion is possible over the entire area of the medium 106 covered with the film 101. Then a conductive film 201 is peeled off from a recording medium 202 to obtain a recordable state again.
