Title: Inner surface-lining process of existing tube having branching tube
Inventor: OTAKI SHIGETOSHI
IPC: B29C39/22
Filed: 1988-04-06
Abstract: PURPOSE:To repair simply the existing tube with a branching tube by a method in which the short tube fitted with a pad is arranged in an existing tube, and its through-hole is caused to coincide with the branching port of the existing tube, and then a plurality of short tubes are connected to the short tube, and further by expanding the pad, the gap between the branching port of the existing tube and the connected tube is sealed closely. CONSTITUTION:An opening port 53 is provided on the tube wall of the short tube 5 in a plurality of short tubes 5 constituting a connected body 2, and the short tube is held on the part of the branching port 11 of the existing tube 1 to which a branching tube 3 is connected. The hollow pad 6 with a through-hole 61 is fitted to the short tube 5, while the through-hole 61 is registered onto the opening port 52. Filler C is injected into the pad 6 through a tube 63, thereby sticking closely the periphery of the branching port 11 of the existing tube 1 to the outer surface of the short tube-body 5. A tube 8 is inserted into the connected body 2, and the tube 8 is brought in rigid state by its expansion. Necessary amount of filler D is injected into a gap S, whereby the connected body 2 is floated in the existing tube 1 and is concentrically arranged. After curing of the filler, filler D is injected into the remaining gap S, and the connected body 2 is held concentrically in the existing tube by curing the filler D.

Title: Semiconductor device
Inventor: YAMASHITA ZENZOU
IPC: H01L21/60
Filed: 1982-05-21
Abstract: PURPOSE:To reduce a semiconductor chip by unnecessitating the area only for bonding pads on the semiconductor chip. CONSTITUTION:The bonding pads 20 are separated from the first metallic wiring patterns 17 of the lower layer by the second insulation films 18, and connected to the patterns 17 at the apertures 19 of the second insulation films 18 which serve as bonding pad lead-out holes. Thereby, even without taking the area only for bonding pads in particular, the bonding pads can be formed only if there is the area for bonding pad lead-out part at least. Thus, the reduction of the chip by 2% or more can be contrived as compared with the conventional one.

Title: Monitor and control equipment
Inventor: NAKAJIMA KAZUO
IPC: G05B9/02
Filed: 1987-04-09
Abstract: PURPOSE:To improve the physical protection properties for operation of a plant by providing an access adaptability deciding part to lock a fact itself that an outsider gives an access to a controller via a man-machine interface. CONSTITUTION:An access propriety deciding part 3 supplies a conditional signal for permission of access to a monitor controller, a plant state signal received from a plant and an access permission request signal received from a control part 2. Then the part 3 decides whether an access to the monitor and control equipment is possible or not. If the access is impossible, a request signal given from a man-machine interface part 1 is neglected. So that it is possible to lock a fact itself that an outsider gives an access to the controller via a man- machine interface 11. As a result, the possibility where the outsider gives an access to the controller is reduced and the physical protection properties can be increased for operation of the plant.

IPC: H01L29/78
Filed: 1983-05-17
Abstract: PURPOSE:To provide a high withstand voltage and a short conductive passage by forming the same conductive type first diffused layer as a substrate and the opposite conductive type second diffused layer to the substrate from the same hole formed in the opposite conductive type diffused layer to the substrate, and forming a control electrode through an insulating film on the first diffused layer. CONSTITUTION:A P type well 2, a field oxidized film 3, a gate oxidized film 4, a polysilicon gate electrode 5, an N<-> type layer 6, an N<+> type layer 8, an aluminum electrode 9, and a channel forming part 10 are formed on an N type silicon substrate 1. Heretofore, the N<-> type layer 6 is added in the forming step in the process, and the layer 6 is formed after a polysilicon gate electrode 5 is formed, with the electrode 4 partly as a mask. A P<+> type diffused layer in the layer 6 becomes source, and P<-> type layer becomes drain, and a channel is formed under the gate electrode 10 of the N<-> type layer. Since the N<-> type layer and the gate electrode side of the P<+> type layer of the source are formed by ion implantation, the channel length of the layer 10 is determined by the difference of the diffused distance between the N<-> type layer and the P<+> type layer.

Title: Loop-back control system
Inventor: SHINBASHI MASAHIRO
IPC: H04B10/03
Filed: 1985-04-24
Abstract: PURPOSE:To prevent the errors or the step-out which is produced when a test of a spare system is carried out asynchronously with the station of the remote side, by transmitting a pattern for a return test also to an optical transmission line of the spare system in case its own station return test is carried out for a multiplex processing part of the spare system through a loop-back part of the spare system. CONSTITUTION:When a loop-back part is formed with a loop-back part 3b of a spare system, a pattern for a return test is sent to an optical transmission line 5b of the spare system via a photoelectric conversion part 4b of the spare system for the station at the remote side. Thus, the spare system of the remote side station which performs various tests asynchronously with each other can receive at least the test pattern. As a result, it can be incriminated that the line 5b is normal. Furthermore the synchronism is secured to eliminate the working errors.
