Title: Optical interruption detector for bidirectional optical transmitter
Inventor: KUWANA ISAMU
IPC: H04B10/07
Filed: 1988-10-24
Abstract: PURPOSE:To surely detect the occurrence of a fault such as the disconnection of an optical fiber in an optical transmission line by providing a polarity inversion circuit inverting signal polarity to each of a transmission circuit and a reception circuit in one direction in the bidirection of transmission directions. CONSTITUTION:When a fault such as the disconnection of the takes place in an optical transmission line 51, a transmission signal from a transmission circuit 52 is reflected fully at the disconnection point and reaches a reception circuit 57 of its own station, and since the arrived signal is inverted for the polarity by a polarity inversion circuit 54, the line is in the state of the code rule violation. Thus, the reception circuit 57 detects the occurrence of a fault immediately by the code rule violation to raise an alarm. Moreover, the reception circuit 53 detects the occurrence of a fault because of the interruption of the arrived signal from the transmission circuit 52. Thus, the disconnection of the line due to the occurrence of a fault in the optical fiber is surely detected by both the sender side and the receiver side.

Title: Mos type semiconductor device
Inventor: TAKATSUKA SATORU
IPC: H01L29/78
Filed: 1986-11-12
Abstract: PURPOSE:To suppress generation of a leakage current due to exposure of radioactive rays and to obtain a MOS type semiconductor device capable of being operated normally with high reliability, by removing the second oxide film in the vicinity of a gate electrode conductor layer and exposing the first oxide film. CONSTITUTION:A surface of a gate electrode conductor layer 18 and a surface of a substrate 11 are exposed in the vicinity of both end parts of an insular region 13, and the gate electrode conductor layer 18 is not in contact with the first layered layer insulating film 19. Therefore, even if holes are generated in the oxide film by an increase in the radiation amount of radioactive rays, the holes are prevented from moving around the gate through the layer insulating film 19 which covers the periphery of the gate electrode conductor layer 18, because the layer insulating film 19 is not formed in contact with the gate electrode conductor layer 18 in the vicinity of the gate end part where a leakage current may be generated. Hence, on an interface between an oxide film 17 and the substrate 11, positive fixed charges are hard to be generated due to radiation of the radioactive rays, so that generation of the leakage current can be suppressed to obtain a normal transistor.

Title: Power steering oil tank
Inventor: YAMASHITA HIROAKI
IPC: F15B1/26
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To prevent generation of vortex flow of work oil within a power steering oil tank. SOLUTION: A substantially cylindrical power steering oil tank is provided with a suction passage 12 at its lower portion and a return passage at its side surface. An inner cylinder 14 is vertically disposed from the top of a container 11 such that a rectifier plate 22 extending and protruding along the height of the container is disposed on the outer peripheral surface of the inner cylinder 14. As the rectifier plate 22 is disposed on the outer peripheral surface of the inner cylinder 14 for protruding, the oil flow turning in the circumferential direction is interrupted by the rectifier plate 22. As a result, the speed content of the oil in the circumferential direction is decreased, thus preventing generation of vortex within the container.
