Title: Laying method for drain pipe
Inventor: SHINODA MANABU
IPC: E03F3/06
Filed: 1990-10-29
Abstract: PURPOSE:To enable proper insertion of a sheath pipe to a spot where connection to an embedded pipe is scheduled by a method wherein a guide rod having a diameter lower than that of a branch pipe mounted on an underground embedded pipe is inserted to a spot where connection of the embedded pipe to the branch pipe is scheduled. CONSTITUTION:Guide rods 3, 3l, and 3k having a diameter lower than that of a branch pipe mounted on an embedded pipe 1 are inserted from a ground to a scheduled connection spot between the embedded pipe 1 and a branch pipe. Sheath pipes 4, 41, 42, and 43 are inserted by means of the guide rods 3, 3l and 3k serving as a guide, and a hole is formed down to the intermediate part of the thickness of the embedded pipe 1 to engage the rod with the hole. This method preconfirms a connection point between the embedded pipe 1 and the branch pipe, rationalizes a drain pipe laying work, shortens a period of a work, and improves safety at a work site.

Title: Boring method of elastic foaming body
Inventor: TANIGUCHI KINYA
IPC: B26F1/16
Filed: 1994-11-01
Abstract: PURPOSE: To bore a hole accurately, beautifully, and simply, even through the hole is a long one, by boring a hole to a compressed elastic foaming body with a rotary cylindrical cutter, and after that, releasing the compression so as to restore the elastic foaming body. CONSTITUTION: The end face of an elastic foaming body 11 at the opposite side of a holding plate is pressed by a pressing body 31 from the outer side, so as to compress the elastic foaming body 11 at a desired amount. After a hole is formed to the compressed elastic foaming body 11 by a rotary cylindrical cutter 41, the compression is released so as to restore the elastic foaming body 11.

Filed: 1991-11-11
Abstract: PURPOSE:To firmly bond a thermister chip to a board as well as to enhance the responsiveness of a temperature detecting element by bonding the temperature detecting element to a thermister conductive board with metallic paste. CONSTITUTION:When metallic paste is filled in between a heater board 2 and a thermister board 105 in such a way as to be, for example, less than 500mum in thickness so as to be sintered at termperature equal to or more than 600 deg.C, solvent and organic binder are burnt out first roughly at 400 deg.C, non-organic binder is fused at 600 deg.C while paste reacts with a ceramic substrate acting as a heater and a thermister substrate or penetrates therein, so that bonding is completed. Metallic powder and the like such as Au, Pt, Cu, Ni and the like is included in the paste used for bonding so that it is conductive. Thus, a thermister chip 102 can firmly be bonded onto the heater substrate by bonding the thermister chip 102 on the substrate with metallic paste. Furthermore, since a metallic paste layer 107 is high in thermal conductivity, thermal contact resistance between the heater and a thermister is almost eliminated.

When carbon is introduced into an AlwGaAs layer, its activation rate is high as compared with a case where it is introduced into an InGaAs layer. As a result, it is possible to supply sufficient holes controbuting toward the conduction of a base current at the inside of the base layer provided with the AlwGa1-wAs region 205 to which carbon has been introduced.
