Inventor: HATSUTA YASUSHI
IPC: H01L29/872
Filed: 1979-04-23
Abstract: PURPOSE:To reduce the series resistance of a Schottky barrier diode owing to the resistance of an epitaxial layer mainly by forming a high density buried region in the vicinity of the contact portion of a metal with the epitaxial layer. CONSTITUTION:There are formed an n-type buried region 6 made of antimony or arsenic and an n-type buried region 31 made of phosphorus having large diffusion coefficient on one main surface of a p-type substrate 7. Then, an n-type epitaxial layer 4 is formed thereon. Thereafter, a cn<+>-type region 5 reaching the region 6 is diffused and formed in the layer 4. Then, the insulating film 3 on the diffused region 31 is selectively removed, aluminum is evaporated thereon and selectively removed to form an anode electrode 1.

Title: Self-routing exchange system
Inventor: ISONO OSAMU
IPC: H04L12/28
Filed: 1989-03-01
Abstract: PURPOSE:To contrive the improvement of reliability and the continuity of a service by detecting a sweep-out confirmation cell from an input module by an output module, and thereafter, switching an ATM switch to a stand-by system. CONSTITUTION:By a switching request to a stand-by system #1 from an existing system #0, a CPU 170 instructs a switching processing to an input module CNV 120, and sends out a sweep-out confirmation cell to an ATM switch 130. A new arrival cell to a virtual call number of a sweep-out object is brought to buffering to the CNV 120. When the confirmation cell is detected, an output module OM 150 informs the arrival to the CPU 170. The CPU 170 extracts the CNV number and the virtual call number, and gives an instruction to the CNV 120 so as to send out a joint cell to an ATM switch 140 after the confirmation cell arrives. Subsequently, the CPU 170 gives an instruction to the OM 150 so as to execute reception switching of the cell from the switch 140. In such a way, since the switch 130 becomes a stand-by system and the switch 140 becomes an existing system, high reliability and the continuity of a service can be secured.

Title: Lsi tester
Inventor: SATOU KATSUYA
IPC: G01R31/28
Filed: 1982-03-29
Abstract: PURPOSE:To prevent cross talk with respect to neighboring input signals by checking oscillation of a test pin at which an oscillation output develops during the testing from the side of a tester. CONSTITUTION:A transistor 11 is connected to an output pin from which oscillation is expected to take place and provides an oscillation in the combination of input patterns. At this point, a control circuit 15 in a tester drives a driver 14 detecting the oscillation from expected output information to raise the emitter potential of the transistor 11, which cuts off the transistor 11 to stop the oscillation. The control system herein used is to drive the driver 14 by operating the control circuit 15 based on an expected output information. This is achieved by activating a driver 4 of the tester connected to an output pin involved according to a test data indicating that the expected output value in the output pin corresponds to oscillation. This allows the implementation of the testing of LSIs which has been hampered by a cross talk.

Title: Oil gas extractor
Inventor: SUZUKI TOSHIO
IPC: H01F27/00
Filed: 1990-03-02
Abstract: PURPOSE:To make the title oil gas extractor relatively easy to carry while enabling a transformer to be easily fitted with a transmission film by a method wherein a single or multiple pipe type gas transmission film is contained in a vessel while the transmission film and an insulating oil pot are structured into one body. CONSTITUTION:When a drain valve 14, the other valves 6, 7 are opened to drive a pump 13, the insulating oil 3 in a transformer is circulated backward from insulating hoses 11b, 11a passing through a vessel 1. By the continuous circulation of the insulating oil 3, the contact time between a transmission film 2 and new oil 3 is elongated thereby stagnating the oil gas in the film 2 while the other valve 9 is opened after the lapse of specific time so that the gas in the film 2 may be led out either by a sensor or a chromatograph for the constituent analysis. Due to the one body structure of the film 2 and a pot of oil 3, the piping for communicating the oil 3 with transformer main body or the connection of oil 3 with the main body by hoses will suffice for the circulation. Furthermore, the title oil gas extractor can be isolated from the transformer main body so that the temperature in the gas extractor may be specified while the change in the gas extraction ratio of the film 2 due to the change in temperature may be easily minimized.
