Title: Carving material, and polyoctenamer resin composition used therefor
Inventor: KITA MASAMI
IPC: C08L45/00
Filed: 1990-11-26
Abstract: PURPOSE:To prepare a carving material which can not only be cast molded, carved, and cut but also polished by using a compsn. mainly comprising a polyoctenamer resin. CONSTITUTION:After the dimerization of butadiene, one of two residual double bonds in the dimer is hydrogenated to give cyclooctene, which is polymerized by, e.g. metathesis polymn. to give a polyoctenamer resin. The resulting resin, as the main component, is compounded with necessary additives such as an inorg. filler (e.g. zinc oxide), a deodorant (e.g. benzaldehyde), a colorant, and various stabilizers to give a carving material. The resin has one double bond for each eight carbon atoms and comprises a mixture of trans and cis-forms concerning the double bond and, by selecting suitable polymn. conditions, the ratio of the trans- to cis-form and the degree of crystallization can be controlled.

Title: Accident point spotting device
Inventor: KANEMAN NAOHIRO
IPC: H02B13/065
Filed: 1994-12-26
Abstract: PURPOSE: To provide a highly reliable accident point spotting device by preventing the erroneous spotting of the device when an accident happens. CONSTITUTION: A ground-fault over-voltage monitoring means 11 detects a ground-fault over-voltage. An AC under-voltage monitoring means 12 detects a voltage drop across a bus caused by a ground-fault. A bus-phase voltage monitoring means 13 detects the occurrence of a power failure caused by the tripping of a circuit breaker. A ground-fault detection locking means 10 discriminates whether an accident happens inside or outside of the container of insulating equipment by logically combining the signals from the means 11, 12, and 13 by means of circuits 14-19 and further discriminates whether or not the rise of gas pressure in the container is caused by the tripping of the circuit breaker.  In case the possibility of erroneous spotting of a ground-fault exists as a result of the above-mentioned discrimination, the locking means 13 inhibits the ground-fault detecting operation of a ground-fault detecting arithmetic means by outputting a ground-fault detection locking signal to the arithmetic means.

Filed: 1993-12-22
Abstract: PURPOSE:To provide the coin dispensing device which presents a stable function for a long time by maintaining engagement between one end of a change slide and the head of a coin base when dispensing no coin. CONSTITUTION:A rear end 22b of a change slide 22 arranged so as to freely appear/disappear inside a coin slide 4, namely, one end on the side of a coin tube is extended while forming a circular arc-shaped notch 22c and further, that rear end 22b enters a recessed part 21a formed at the head part of the coin base 21 and engages the head of this coin base 21 when dispensing no coin. Thus, the weight of coins housed in the coin housing hole of a pay-out slide is supported by the change slide 22 and the coin base 21. Therefore, even when the device is used for a long time, one end of the slide 22 is prevented from being hung down by being changed with the passage of time because of any factor such as the weight of coins so that the operation lock of the device can not be generated by abutting the coin base and the coin when returning to the initial position of the pay-out slide.

Abstract: PURPOSE:To construct a steel sheet pile wall in precise and less-expensive manner, by using a plurality of guide piles equipped with steel-sheet-pile claws, without employing guide frames composed of guide piles and guide beams. CONSTITUTION:First of all, a plurality of guide piles 1, sufficiently longer than steel sheet pile 2 and having steel-sheet-pile calws 1a along the axial direction, are prepared. On the normal line of placing of these steel sheet piles 2, the guide piles 1 are driven into the ground 15 at intervals of integer-fold of the width of the steel sheet pile 2, leaving a prescribed length protruding above the ground surface. The steel sheet piles 2 are driven in thereafter, having them engaged to the claws 1a of the guide pile. With this method, guide piles for temporarily-placed guide frames will not be required to be prepared separately as conventionally done so, and time and labor for installing and removing them can be saved.

Filed: 1990-11-27
Abstract: PURPOSE:To improve the adhesion between wirings and an insulation film by placing a Cu alloy coverage layer between Cu-based wiring and a protective insulation film. CONSTITUTION:A SiO2 or other insulation film 5 is placed on the active region formed on an Si substrate 4 and after a thin Cu film has been formed by sputter deposition on the surface of insulation film 5, patterning is performed to process a Cu wiring main body 1. Next, a thin Cu-Si alloy film 2a is selectively grown by a CVD process on the exposed surfaces of the Cu wiring main body 1 and after that, a CVD process is again used to form a PSG protective insulation film 6 on the Cu wiring 3a covered with a Cu-Si alloy layer and on the insulation film 5 to complete the semiconductor device. During this, since the Si contained in the Cu-Si alloy coverage layer 2a forms an SiO2 protection layer, no oxidation of the Cu wiring main body 1 occurs. As a result, excellent adhesion can be achieved between the Cu wiring 1 and the protective insulation film 6.
