Filed: 1985-12-18
Abstract: PURPOSE:To provide a friction material which is superior in mechanical strength and possesses fade resistance, by a method wherein heat treatment is applied under a predetermined terms to the friction material molded mixing up a filler such as graphite or barium sulfate and a binding material based on thermosetting resin such as phenolic resin with a base by making use of a fiber as the base. CONSTITUTION:Heat treatment is applied to a friction material molded by mixing up a filler such as graphite or barium sulfate and a binding material based on thermosetting resin such as phenolic resin with a base by making use of a fiber such as a steel fiber or an inorganic fiber as the base under predetermined terms wherein the temperature is made more than 300 deg.C and less than 400 deg.C and a heat treatment period of time is made more than 15min and less than four hours within a nonoxidation atmosphere. During the heat treatment the friction material does not deteriorate a material by oxidative destruction of resin which is an ingredient of the friction material and oxidation of the steel fiber, a weight reduction and heating of the friction material are controlled also and dissolution of a binding material is progressed slowly. In consequence of the above, the whole of the friction material can be heat-treated uniformly by reducing a difference between the surface and inside of the friction material based on the heat treatment.

Title: Image recording and reproducing device
Inventor: SUMINO SHINYA
IPC: G06T13/80
Filed: 1994-11-18
Abstract: PURPOSE: To provide an image recording-reproducing device which can record many images in real time and with high picture quality. CONSTITUTION: In the first recording mode, an encoder 2a encodes the signals in real time or almost in real time and a recording circuit 3a records these encoded signals on a fast access recording medium 4a. At the same time, the signals which are once recorded are decoded by a decoder 6a and encoded by an encoder 2b which is not of fast operating speed but of high picture quality and of low rate. These encoded signals are recorded on a slow access recording medium 4b by a recording circuit 3b. Then an erasing circuit 9 erases the signals of the medium 4a corresponding to the same image as that recorded on the medium 4b. The picture quality is never virtually deteriorated and the recordable image capacity of the medium 4b is increased as the time elapses. Furthermore, the unimportant signals are erased by an erasing means when the recordable area of the medium 4b is small.

Title: Vending machine
Inventor: ICHINOSE NOBUHIKO
IPC: F25D11/00
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To prevent a change of a taste of a commodity and to simplify an operation switching work by providing an operation control means for stopping heating and cooling means during a set time from a time point of switching from a heating operation to a cooling operation, and then driving the cooling means. SOLUTION: In the case of switching an intermediate camber 13 or a right chamber 14 from a heating operation to a cooling operation, heaters 22, 26 and coolers 20, 24 or the like are stopped for a set time (e.g. 10 hours) from the time point of switching by a switch, and then the coolers are driven to cool the chamber 13 or the chamber 14. Thus, canned drink or the like contained in the intermediate or right chamber is naturally cooled from a high temperature state, and then cooled by the coolers. Accordingly, since the commodity is not quickly cooled from the high temperature state, its taste is not changed. Since an operation switching control is automatically executed by an operation control means if a changeover switch is operated, its work can be simplified.

Abstract: PURPOSE:To enhance a cooling effect by connecting a dehumidifier for preventing condensation to a local cooler installed to the dry well in the reactor container and blowing out the cold air cooled in this dehumidifier to the high- temp. area of the dry well. CONSTITUTION:The air in the dry well space is circulated and cooled by the local cooler 8 and the air cooled by the local cooler 8 is further cooled by the dehumidifier 11 to the cold wind which is supplied through an air feed duct 7 out through an air feed nozzle 12a into the space 5 between a reactor pressure vessel 1 and a shielding wall 3. The air is cooled by the humidifier 11 and is thereby lowered in temp., by which the supply rate to the space 5 can be decreased and, therefore, the pressure on the inner side of the shielding wall 3 is lowered and the leakage to the heat insulating material of the reactor pressure vessel 1 and the outflow of the cold wind from an aperture 10 are decreased. The cooling efficiency is thus improved. The temp. rise is lessened and the cooling efficiency is enhanced.

Abstract: PROBLEM TO BE SOLVED: To perform plural electrode gas shield arc weldings with one wire reel and one set of wire feeding device in a good workability by feeding out plural pieces of wires and supplying to plural electrode torches, in a wire feeding device. SOLUTION: In the wire feeding reel, two pieces of wires 2A, 2B are coiled and this is one set of two pieces. Two pieces of wires 2A, 2B are made to develop the arcs with the same arc length. In the case of lengthening the arc length of the wire because only wire 2B is excessively melted in some reason, in a low voltage characteristic, the current in the wire 2A becomes high and the current in the wire 2B becomes low, and the melting speed of the wire 2A becomes quick and the melting speed of the wire 2B becomes slow. Then, the arc length of the wire 2A is gradually lengthened and the arc length of the wire 2B is gradually shortened and these arc lengths are returned back to the original same length condition. In such a way, both wires are uniformly melted in sec order.
