Title: Pollution-proof copper alloy
Inventor: MINAMOTO KENKI
IPC: C22C9/04
Filed: 1987-10-22
Abstract: PURPOSE:To obtain the titled Cu alloy having excellent corrosion resistance and less surface coarseness and to which oceanic life, etc., are hard to adhere by incorporating specific amounts of Sn, Fe, Ni, Al, Zn and As to Cu. CONSTITUTION:Since oceanic life is hard to adhere to the outer plate material of a hull, pipeline for seawater, valve, oceanic structure and its outer base plate or wire netting, etc., the Cu alloy contg. by weight, 0.5-3% Sn, 0.05-1.0% Fe, 0.2-2.5% Ni, 0.5-3.0% Al, 10-35% Zn and 0.02-0.06% As is regulated to the material in order to prevent or decrease the above-mentioned adhesion. By this method, the pollution of the outer plate and the decrease of the speed caused by the adhesion of oceanic life when said alloy is used as the outer plate material of a hull are prevented; and since the alloy has excellent corro sion resistance, the generation of unevenness by the corrosion caused by sea water and the lowering of the speed caused by friction with seawater are prevented.

Title: Method for foam-molding core material integrally with skin material
Inventor: NAKAMICHI MASAHIRO
IPC: B29C39/26
Filed: 1986-11-10
Abstract: PURPOSE:To productively manufacture an integrally foam-molded item with no quality defects such as sink mark, blister and the like by a method wherein a foaming mold having a vent port is employed and at the same time a core material, the wall thickness of which is made thin at its part contacting the vent port, is used in order to open a vent hole with a pin through the vent port in said thin-walled part of the core material after the hardness of a foam reaches the predetermined value. CONSTITUTION:A vent port 12 is bored in a top force 4 so as to correspond to the thin-walled part 10 of a core material 1. The core material 1 used has the thin-walled part 10. When a foam 15 starts to harden, an air cylinder 14 is put into actuation so as to stick a movable pin 13 in the thin-walled part 10 of the core material 1 and, and then the pin is lifted in order to make a vent hole in the thin-walled part 10. The compressed gas stored within the foam 15 flows through the vent hole and the vent port 12 outside the forces. At that time, since the foam 15 hardens to some extent, no efflux of the foam through the vent hole occurs, resulting in allowing to release the foam from the forces without developing sinkage or blister.

Title: Sheet for release
Inventor: KATO TAKAHISA
IPC: C09J7/02
Filed: 1990-10-05
Abstract: PURPOSE:To obtain an enamelled highly smooth release sheet by fast sticking a resin composition layer to a supporter, curing the resin composition layer by applying electron rays and peeling an unnecessary film. CONSTITUTION:A resin composition layer mainly comprising an electron radiation curing silicone resin is formed onto a film, and the resin composition layer is superposed and fast stuck to a supporter. The resin composition layer is cured through electron radiation under an adhesive state, and then film is peeled, thus acquiring a highly smooth enamelled release sheet, to which the smoothness of the surface of the film is reflected. Since the electron radiation curing silicone resin is interrupted from the outside air by the film, no curing inhibition is generated by oxygen, thus reducing the usage of nitrogen and lowering exposure. Polysiloxane, a molecular terminal or a side chain of which has a functional group selected from an acryloyl group, a methacroyl group, a vinyl group, an epoxy group, etc., is used as the electron radiation curing silicone resin.

CONSTITUTION:AE sensor 3 is fixed to a bearing 2, and an output sent through an amplifier 5 and a band-pass filter 6 is detected and rectified by a detector 7. A waveform processor 8 receives an output sent by a level setting device 10 ad a detecting output signal, and outputs a pulse shape for the detecting output signal higher than a fixed level. A pulse counter 9 counts the number of the above square pulse for a time specified by a reference time setting device 11. The number of the square pulse is compared with the abnormal number of count established by a setting 12 for the number of count using a comparator 13 for the number of count, and when the number of the square pulse is more than the above abnormal number of count,an alarm 14 and alarm output 15 give warning. Since AE method can give response more quickly than a former method, abnormality in bearing can be detected more quickly than ever.

IPC: H04W36/18
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption and to prolong battery service life by efficiently using seamless handover. SOLUTION: Battery voltage VB is judged whether it is equal to or higher than a threshold TH1 or lower then the threshold prior to handover control, the handover control mainly to perform the seamless handover is executed by selecting a first mode, when the battery voltage is equal to or higher the the threshold and on the contrary, only normal handover control is executed by prohibiting the seamless handover by selecting a second mode when the battery voltage VB is lowered to the one lower than the threshold TH1.
