Title: Signal wiring board
Inventor: SHIMIZU FUMIHIKO
IPC: H01P3/08
Filed: 1989-03-14
Abstract: PURPOSE:To contrive miniaturization of a board and speeding up of a transmission signal by specifying the relation among a gap width between respective transmission lines, a space between the transmission lines with those of neighboring channels, and the thickness of dielectrics. CONSTITUTION:A plurality of channel signal transmission paths 131-133 are made up by differential transmission paths in which a pair of transmission lines C1 and C2 are disposed in parallel respectively. Respective transmission lines C1 and C2 are constructed so that a gap width G between respective lines C1 and C2, a space S between the transmission lines with those of neighboring channels, and the thickness H of dielectrics may satisfy the following relation: G<H<S. The differential transmission paths in which respective channel signal transmission paths 131-133 are formed by a pair of the transmission lines C1 and C2 make combination between the transmission lines C1 and C2 stronger than that between the channel signal path and a neighboring channel signal path. Then coupling of electric lines of force between channels is suppressed and then crosstalk decreases. Miniaturization of a board and speeding up of a transmission signal are achieved.

Title: Test piece for bending-strength test and bending-strength testing apparatus using the piece
IPC: G01N3/34
Filed: 1992-03-18
Abstract: PURPOSE:To obtain a test piece for bending-strength tests, by which a plurality of times of bending tests can be performed with a single test piece and the workability in the execution of the test is improved. CONSTITUTION:A test piece 1 has a circular shape or a rectangular shape. The overall length of the test piece is long enough to perform bending strength tests a plurality of times. When the distance between upper supporting points is made to be L1 and the distance between lower supporting points is made to be L2, the overall length of the test piece 1 is 1/2 (L1+3L2) or more, e.g. 140mm. Thus the bending-strength tests of a plurality of times can be performed with one test piece 1. The tests of a plurality of times can be performed by mounting the test piece once on the jig. Since a plurality of data values are obtained from one homogeneous test piece 1, whose surface is machined, the effect of the surface-machined state becomes less, and the accuracy of the data is improved. Furthermore, the useless unused part by the cutting of the test piece can be reduced, and the uselessness of raw material is less.

Title: Power supply circuit
Inventor: OOMURA TADASHI
IPC: H02M3/28
Filed: 1982-04-14
Abstract: PURPOSE:To control electric power supplied to an output side and to stabilize a voltage between output terminals by controlling the turn-on angle of a capacitor for resonance provided on a secondary side according to the output voltage. CONSTITUTION:When a load 18 is lightened until the output voltage Vo rises above the voltage value of a standard load, a control pulse Pc increases in pulse width in proportion to the voltage rise, and the turn-on period of a transistor (TR) Qb becomes longer, so the turn-on angle of the 2nd capacitor Cb increases. Then, electrostatic energy charged in the 2nd capacitor Cb increases accordingly. The more energy a parallel resonating circuit 11 is charged with, the less electric power the load side 18 is supplied with. As the load supply power is reduced the output voltage Vo drops, so the turn-on period of the TRQb is controlled by the control pulse Pc to stabilize the output voltage Vo.

Filed: 1989-03-15
Abstract: PURPOSE:To improve the corrosion resistance by forming the film which basic material is epoxy denaturated silicon resin in the inner surface of a metal pipe with the predetermined thickness, and covering the outer surface of the pipe with the heat insulating material made of the resin foaming material or the rubber sponging material. CONSTITUTION:The film which basic material is epoxy denaturated silicon resin obtained by mixing epoxy resin 5-50% and silicon resin 50-95% is formed in the inner surface of a metal pipe, especially a copper pipe, for hot-water supply and water supply with a thickness of 5-400mum in consideration of the adhesion, the durability and the heat resistance. The outer surface of the pipe is covered with the heat insulating material made of the plastic foaming material and the rubber sponging material. In this case, if the thickness of the film of epoxy denaturated silicon resin is less than 4mum, the formation of the even film thickness is hard, and if the thickness is more than 400mum, the fine crack is generated at the time of bending-process. The thickness of the film is therefore limited as described before. The processability and the workability is maintained and while a covered heat insulating pipe with inner film having the fine corrosion resistance can be obtained.

Abstract: PURPOSE: In a discharge lamp comprising plural luminous tubes fitted in an outer tube, to largely reduce the restarting time by inserting a heat-resistant material which transmits visible light but reflects infrared rays between each pair of luminous tubes.  
     CONSTITUTION: With a voltage applied through a stabilizer to two luminous tubes 1 and 2 each consisting of a high-pressure mercury lamp, the more eaily startable tube, the tube 1 for example, is started. A stable lighting condition will be reached in several minutes. With a voltage applied immediately after a turn-off operation, the radiant heat (infrared rays) from the lighted tube in reflected by a heat-resistant heat-shielding glass plate 23 so that the unlighted tube 2 is kept at low temperature. As a result, the time until the tube 2 is started, i.e. the restarting time for the lamp as a whole, is reduced. As the plate 23 transmits visible light, it cannot reduce the total light flux of the tubes 1 and 2 and cannot damage optical characteristics.
