Title: Hot water heater having function of heat insulating operation
Inventor: TSUJI EIICHI
IPC: F24H1/10
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a hot water heater having a function of heat insulating operation which does not so much lower the property of heat insulating operation of the hot water heater, ensures durability and safety of a burner or the like, and realizes sufficiently long life of the hot water heater. SOLUTION: A hot water heater having a function of insulating operation comprises a function of heat insulating operation which carries out heat insulating operation by bringing a burner mechanism 6 into a combusting status even when hot water is not supplied. The hot water heater controls itself so that, during heat insulating operation, heat insulating combustion is started when water temperature in a heat exchanger 5 becomes not more than the temperature for starting heat insulating combustion, and that the heat insulating combustion is stopped when the water temperature in the heat exchanger 5 becomes not less than the temperature for stopping heat insulating combustion.  There is provided a control unit 15 which controls heat insulating combustion so as not to start unless a given period of combustion prohibition elapses after the end of the heat insulating combustion, in a condition where the heat insulating combustion is temporarily stopped because the water temperature in the heat exchanger 5 has risen to not less than the temperature for stopping the heat insulating combustion, and thereafter the water temperature in the heat exchanger 5 again has lowered, at an earlier occasion, to not more than the temperature for starting heat insulating combustion.

Filed: 1986-12-02
Abstract: PURPOSE:To output a stable SSCAN signal by providing a resin molding which covers a photosensor chip to which anode or cathode is connected to wiring on a substrate through a wire and the substrate only at necessary parts for wire protection. CONSTITUTION:The output terminal of the anode or cathode of the photosensor chip 21 is connected to the wiring 24 on the substrate 22, but the other output terminal is connected to different wiring 26 on the substrate through a bonding wire 25 from the tip surface of the chip 21.

Title: Brake pad made of carbon fiber reinforced carbon compound material
Inventor: WAKAMATSU TOMOYUKI
IPC: F16D65/02
Filed: 1992-10-02
Abstract: PURPOSE:To prevent the vibration of a pad generated in association with the wear of a disc by setting an angle formed by the friction face and side face of the pad to be over 90 deg.. CONSTITUTION:A pad 1 has the friction face 3 and the side face extended from the friction face 3, with the inclination of more than 90 deg. and the sectional area becomes larger toward the support face 4 from the friction face 3. Wear is generated to both pad 1 and disc 2. In the disc 2, the center part of the friction face is recessed, and both ends are worn into a thick I-shape. Also in the pad 1, the friction face 3 recedes, and the peripheral edge part is rounded. Since the pad 1 is formed in such a way as to be larger in cross section toward the support face 4 from the friction face 3, the contact area with the disc 2 becomes larger with the advance of wear. The disc 2 does not therefore bite the pad 1 so as to prevent the vibration of the pad during braking.

IPC: G11B5/85
Filed: 1986-12-03
Abstract: PURPOSE:To produce a magnetic recording medium not orientated magnetically and having no magnetization anisotropy and with high magnetic coercive force and high productivity, by laminating successively and continuously a chrome surface layer and a thin film type ferromagnetic layer containing cobalt by a specific quantity or more on a flexible non-magnetic substrate by a vacuum vapor-depositing method.

A vapor-deposited substance can be evaporated by either a resistance heating method or an electron beam heating method. By executing continuously the vacuum vapor deposition of the surface layer and the magnetic layer, the overall vapor deposition time can be shortened, and a merit for the productivity is generated. As for the content of cobalt as a ferromagnetic metal, >=50wt% is desirable, and 60-95wt% is more desirable.

Title: Device and method for processing data, and transmission medium
Inventor: TANI ATSUSHI
IPC: G06N3/00
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To make the pattern of time series data possible to be automatically turned into clauses. SOLUTION: Prescribed patterns of time series data are selectively stored in recurrent type neural networks 1-1 to 1-n and when the learn pattern appears in the inputted time series data, that detecting signal is outputted. This detecting signal is passed through gates 2-1 to 2-n and synthesized by a synthesizing circuit 3. The gate sequence corresponding to the opening state of the gates 2-1 to 2-n is inputted to recurrent type neural networks 11-1 to 11-n of a high- order hierarchy. When the stored pattern is detected, the respective recurrent type neural networks 11-1 to 11-n output that detecting signal through gates 12-1 to 12-n. Thus, since the network is made into a hierarchical structure, the time series data can be automatically made into clauses.
