Title: Welding method for joint of long floor material
Inventor: AIKAWA SATORU
IPC: B29C65/20
Filed: 1980-05-02
Abstract: PURPOSE:To obtain an excellent finished appearance without using any joint material by inserting a heating body into the joint part of the long floor material laid without providing of an aperture and by heating and welding the joint part by the heating body. CONSTITUTION:A bonding agent 6 is applied on a foundation 7 such as mortar and long floor material sheets 2 and 2' are laid thereon closely to each other and without any aperture being provided between them. Into the joint part 5 of these sheets is inserted the heating body 3 of a heater kept at a desired temprature. The heating body 3 can be inserted into the joint part 5 easily, though the long floor material sheets 2 and 2' are laid closely to each other, since they are made of flexible material such as polyvinyl chloride resin. The end parts of the sheets 2 and 2' are heated by the heating body 3 and made to be weldable to each other. When the heating body 4 is removed, the end parts of the long floor material sheets 2 and 2' are turned closely contact with each other as before the insertion of the heating body and are cooled, set and bonded.

Abstract: PURPOSE:To prevent sticking of In to rolls and to allow the easy removal of Japanese paper by an acid treatment after pressurized joining by superposing the extremely thin Japanese paper on both upper an lower outer sides, inserting the above into the rolls and subjecting an Au layer and an In layer to pressurized joining at a specific draft. CONSTITUTION:In tapes 2' are superposed on both the upper and lower outer sides of the Au tape 1' in-between and the Japanese paper 6 is superposed on both the upper and lower outer sides thereof. The superposed tape materials are then inserted between the upper and lower press rolls 7 and 8. The Au tape 1' and the In tapes 2' are then subjected to the pressurized joining at 20 to 30% draft. The Japanese paper 6 is thereafter removed by the acid treatment with dilute sulfuric acid to obtain the laminated brazing material tape 3' consisting of the Au layer and the upper and lower In layers. The sticking of the brazing material to the rolls is, therefore, obviated and the generation of the crack and peeling in the brazing material is obviated. The stable laminated brazing material 3' is thus obtd.

IPC: H04Q3/72
Filed: 1981-04-21
Abstract: PURPOSE:To simplify the constitution of a DC monitoring circuit by comparing the output of a differential amplifier with that of a threshold-level setting circuit for monitoring a load current. CONSTITUTION:When a current flowing through a load resistance 18 in an off-hook state is I, the output voltage of an operational amplifier 1 is V1, and the output of a threshold-level setting circuit 12 consisting of a transistor (TR)11 and a diode 12 is V2, the value of the load current I with V1=V2 is a threshold value during DC monitoring. This threshold current is determined only voltage drops across the TR11 and diode 12, and the resistance value of a constant resistance R for current supply, so that any influence of variation in powr voltage is not exerted at all. Further, a voltage difference between terminals 13 and 14 is basic information on arithmetic, so an in-phase disturbing voltage is hardly inputted from a line.
