Title: Vswr detection circuit
Inventor: SASAKI KIYOTAKE
IPC: G01R29/08
Filed: 1994-06-27
Abstract: PURPOSE:To detect the standing wave ratio VSWR accurately by disposing two detection connectors on one surface of a waveguide while spacing apart by a distance corresponding to a quarter of wavelength in the waveguide. CONSTITUTION:Two detection connectors 3, 4 are disposed on one surface of a waveguide 2 while being spaced apart by a distance corresponding to a quarter of wavelength lambda in the waveguide. Outputs from the connectors 3, 4 are detected through detectors 6a, 6b and converted into DC levels 7, 8. The DC levels 7, 8 are compared through a comparator 9 and the amplitude of VSWR is detected based on the level difference. Since A-B=lambda/4, the difference of outputs detected at points A and B corresponds to the amplitude of VSWR at all times. Furthermore, since the connectors 3, 4 are located at positions just corresponding to the positive and negative peaks of VSWR, the difference of detected output represents the amplitude of VSWR itself.

Abstract: PURPOSE:To increase photoelectric current without increasing an area of a base/collector junction region by providing a lens which increases strength of light which is injected to a minority carrier diffusion region and proximity thereof. CONSTITUTION:A P-type base region 3 exists in a silicon substrate 1 which becomes a collector region and a minority carrier diffusion region 7 wherein minority carrier of the same conductivity as a collector region diffuses exists in a periphery of the base region 3. A silicon oxide film 17 is formed on a main surface of the silicon substrate 1. A through-hole is formed in a silicon oxide film 17 on an emitter region 5, and an emitter electrode 13 is connected with the emitter region 5 through the through-hole. A lens 15 is formed on the silicon oxide film 17 to increase strength of light injected to the minority carrier diffusion region 7 and a minority carrier diffusion region proximity 23. Therefore, it is possible to increase photoelectric current without increasing a chip size.

Abstract: PURPOSE:To prevent unreasonable engagement strain on a thin plate while the thin plate is temporarily fixed by drilling a clearance hole on the outer boundary part of a cauking means for preventing the thin plate from extending to a pressed joining face and reducing an influence from a temporarily fixing means. CONSTITUTION:An axle-hole thin plate 12 with a temporary fixing means is snugly held through a pressed joining face 20 to each steel core 21. The thin plate 12 has each clearance hole 30 or 31 around a separation hole 15 and a caulking joining part 17, and by these clearance holes 30 and 31 a circumferential part is divided into three. The thin plate 12 is joined through three narrow rib members to the pressed joining face 20, and thereby horizontal stress that enlarges the thin plate 12 outward during the caulking is attenuated through the clearance holes 30 and 31. At the same time, a small quantity of horizontal stress is transmitted through the rib-shaped joining member 32. The joining hold force by the pressed joining face 20 is not excessive than that of a push- back step.
