Title: Pipe hole repairing method
Inventor: KAMEI HIROMASA
IPC: B23K20/00
Filed: 1986-03-27
Abstract: PURPOSE:To improve the quality in repairing by inserting the sleeve having a taper inner face into an over-cut pipe hole and by inserting a hollow pipe expander from both sides as well, then by performing a recutting with the diffusion joining of the pipe hole face and sleeve. CONSTITUTION:The sleeve 2 which is thin in thickness and of the same material with that of a pipe plate 1 and which has the taper inner face 2a spreading to both sides is fitted into an over-cut hole 1a and the hollow pipe expanders 3, 4 having the same tapers 3a, 4a as that of the sleeve taper 2a are set by inserting into the pipe hole 1a. In this case, similar sleeve and pipe expander are set for preventing the deformation to the adjacent pipe hole. The hole 1a is then sealed with sealing members 5, 6 and the sleeve 2 is subjected to a diffusion joining to the hole 1a with a high frequency heating coil 7 as well and the re-cutting is performed by removing the pipe expanders 3, 4. In this way, the repairing quality is improved because of the bad effect onto the adjacent hole being prevented.

IPC: H01L27/10
Filed: 1988-03-25
Abstract: PURPOSE:To prevent the increase of the resistance value of a wiring composed of an aluminum film, and to increase the operation speed of a device by connecting the wiring to a semiconductor region through interposition of a metallic film obviating precipitation in the aluminum film of the main component of a substrate. CONSTITUTION:In a device with a wiring 17 consisting of an aluminum film connected to a semiconductor region 13 in the main surface of a semiconductor substrate 1, the wiring 17 is connected to the semiconductor region 13 while interposing a metallic film (a titanium nitride film, etc.) 14C preventing precipitation into the aluminum film 17 of the main component, silicon, of the substrate 1. Consequently, silicon as the principal component of the semiconductor substrate 1 is not precipitated into the wiring 17 made up of the aluminum film. Accordingly, the increase of the resistance value of the wiring is obviated, and the working speed of the semiconductor integrated circuit device is accelerated.

Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To provide a switch by which the control of ON/OFF and analog amount or the like can be conducted with a simple operation without providing a mechanical moving portion. SOLUTION: A membrane spacer 8 which is somewhat thicker than the thickness of a pressure sensitive conductive rubber 9 is arranged at the portion C of the membrane sheet of a membrane switch, and the pressure sensitive conductive rubber 9 is bonded to a contact portion 3 and is arranged at the window 7 portion thereof, and a contact portion 2 is faced to the pressure sensitive conductive rubber 9 by folding back the portion A of the membrane sheet 1 at a portion B. When no pressing force to the portion A exists, a gap exists between the contact portion 2 and the pressure sensitive conductive rubber 9 so that printed conductors 4, 5 are off.  When the pressing force is applied to the portion A, the contact portion 2 and the pressure sensitive conductive rubber 9 are put in contact with each other to be ON, but the pressure sensitive conductive rubber 9 has a fixed resistance value, and with the increase of the pressing force, the resistant value becomes smaller. Accordingly, just by adjusting the pressing force, the control of various analog values becomes possible.

Filed: 1989-03-22
Abstract: PURPOSE:To allow each station to share a secret key and to use the key for cryptographic/decoding processing by allowing a center to calculate a public open value from ID information when each center registers the ID information of its own station, opening the value in public to each station together with the ID information and allowing the center to store one storage value calculated from the IS value into a secret information storage memory. CONSTITUTION:When a station A2 subscribes to a network or a system engaging with secret communication, the station A2 sends ID information IDA to the center 1, the center 1 calculates alphaA as the storage value and sends the alphaA to a secret information storage memory 3 in the station A2, a value GA is used as a value open in public and listed in an open public list 4 together with information IDA. Similarly, when a station B5 subscribes to the system, information IDB and an open public value GB are listed in the list 4 and new stations are subscribed with similar processings. When the stations A2, B5 share a key, the ID information and the open public value of the opposite station are used to make the calculation of the key and the key is used for cryptographic/decoding operation not via a communication line 7.
