Title: Organic electrolyte cell
Inventor: SHIRAI IWAO
IPC: H01M6/16
Filed: 1987-04-17
Abstract: PURPOSE:To provide good contact between positive and negative electrodes so as to stabilize cell characteristics by using an active material consisting of three layers-namely, negative electrode black mix, positive electrode black mix, negative electrode black mix, and interposing a layer of insulating material between the base of the positive electrode and negative electrode black mix. CONSTITUTION:A positive electrode black mix 1 is formed by adding 10 wt.% graphite as conductor and 5 wt.% fluoride resin as binder to 85 wt.% copper oxide, and forming the product into pellets. Negative electrode black mixes 2, 2' are punched rolled lithium plate, and is positioned above and below the positive electrode black mix 1. An insulating layer 3 formed from a synthetic resin prevents electrical contact between a positive electrode case 4 and the negative electrode black mix. The positive electrode black mix 1 can therefore expand in a vertical direction with the discharge reaction, thereby maintaining good contact with the negative electrode black mixes 2, 2', and stabilizing the internal resistance of the cell and its discharge properties.

Title: Checking of semiconductor laser
Inventor: KUNO MASAAKI
IPC: H01S5/00
Filed: 1989-04-14
Abstract: PURPOSE:To make operational efficiency excellent when checking is performed and reduce checking time by causing a laser to emit a light after impressing forward bias and taking out a photoelectric current after performing photodetection of an outgoing light by a semiconductor laser which is adjacent to the above laser in the direction of a resonator and is impressed by reverse bias. CONSTITUTION:Respective checking probes 6a and 6b are made to be contact with each electrode 11 of two semiconductor lasers 100 and 200. A laser light is emitted by impressing forward bias to the laser 100 with a laser drive means 4. The photodetection of a laser light is performed by impressing reverse bias to the laser 200 with a photoelectric current detecting means 3 and then a threshold value is checked by detecting a photoelectric current. In such a case, the laser 200 which is impressed with reverse bias as a photodetector finds out a variation point P at which a naturally emitted light turns to a laser-oscillation light, i.e., a threshold value because linearity is recognized in the relation between detected light intensity and an output current. Then the quality of lasers which are adjacent is discriminated even though a laser having unknown photodetection characteristics is used as a photodetection means and checking time can be reduced.

Title: Hot water supplier
Inventor: ITO KOJI
IPC: F24H1/00
Filed: 1986-04-25
Abstract: PURPOSE:To make it possible to carry out an automatic hot water supply and pouring of high-temperature hot water by branching a hot water supply side into two or more paths, inputting a signal emitted from a water quantity sensor through a controller into a path communicating with a bathtub to vary the water quantity, and providing a water quantity control mechanism, an edge cutting device and a check valve. CONSTITUTION:When an automatic hot water switch is turned ON, a signal of opening enters a water quantity proportional valve 12 from a controller 9. Water flows into a bathtub 18 from the lower part of the side surface of the bathtub 18 through the route of a water quantity sensor 1, a water supply circuit A, a heat exchanger 3, a hot water supply circuit B, a water quantity proportional valve 12, a vacuum breaker 13, a check valve 19, and a hot water supply circuit B1. With more than an ignition water quantity the combustion of a burner 5 is started. The temperature of hot water is detected by a thermistor 11 which controls the quantity of gas to be supplied depending upon a difference between the detected tempera ture and a preset temperature, thereby to hold the temperature of hot water at a predetermined value. When the temperature of hot water reaches an automatic hot water supply quantity set value, the water quantity proportional valve 12 is closed, the combustion of the burner 5 is stopped and the hot water supplier is in a stop state. When a high-temperature hot water water pouring switch is turned ON, hot water flows in the same manner as the case of the automatic hot water supply and is supplied into the bathtub from the lower part of the side surface thereof. Since hot water of 80 deg.C is blown off downward through the lower part of the side surface of the bathtub, the temperature distribution is exceedingly good.
