Filed: 1984-02-24
Abstract: PURPOSE:To increase effective area of electrode by forming an electrode end seal so that gas inlet and outlet ends are made to a specified width and other ends are made narrower than the gas inlet and outlet ends. CONSTITUTION:An electrode end seal 12 is formed so that gas inlet and outlet ends 12a are made to a specified width and other ends 12b are made narrower than the gas inlet and outlet ends 12a. A gas pathway 8a which is used to supply gas is installed in power generating area increased by making narrow the ends 12b than the ends 12a. When a fuel electrode 1 and an oxidizing electrode 2 having the gas pathway 8a are used to form a unit cell, effective area of the electrodes 1 and 2 is increased by the area indicated by slant lines 13 since gas pathways 8 and 8a are intersected at right angles.

Abstract: PROBLEM TO BE SOLVED: To securely prevent freezing by providing a valve for opening/closing a hot water delivery part and a temperature-sensor in a pipe and install a controller to open the valve when the sensor detects a water temperature lower than a specified temperature. SOLUTION: Solenoid valves 2 are installed in both hot water supply pipe line 12 and water supply pipeline 13 and a temperature sensor 3 is equipped in a confluent pipeline 14. When the temperature sensor 3 equipped in the confluent pipeline 14 detects a lower water temperature than a specified value, a detected signal is input from the temperature sensor 3 into a controller 4. A hot water delivery part 1 is opened by the output signal from the controller 4 to delivery hot water and discharge water in the pipeline by the controller. That is, the opening/closing valve 2 attached to the hot water supply pipeline 12 is opened and water and hot water are supplied from the hot water supply pipeline 12 and the water supply pipeline 13 and discharged from a faucet 8 or shower head 9 for a hot water discharge part 1.  Accordingly, freezing of water in a water pipeline can be automatically prevented in a cold time, in a simple constitution.

Filed: 1991-02-27
Abstract: PURPOSE:To measure a flow continuously, by correcting a signal measured by a mass flowmeter on the basis of the flow signal found from the loss value per constant time, of a vessel in which a measuring fluid is put. CONSTITUTION:Weighed material is continuously supplied with a feed pump 2 from a weighing vessel 1 to a mass flowmeter 3, and the measured value A is obtained by utilizing Coriolis force.

CONSTITUTION:The waste gas from three units of hot stoves 1 passed through a duct 3 and is led into a heat exchanger 4 through the pipeline 5 to which a lead-out pipeline 11 connects. After it is heat-exchanged with air for combustion from a blower 8, it is exhausted from a chimney 2 through the pipeline 6 to which a lead-out pipeline 12 connects. If at this time, the amount of waste gas is large (e.g., at the time of combustion of two units of hot stoves), part of the high- temperature waste gas is passed through the heat exchanger 4 and the rest is let to a water granulated slag drying unit 13 through the lead-out pipeline 11. At the combustion of one unit of the hot stove 1, the entire amount of the waste gas is passed through the heat exchanger 4, after which part of the low-temperature waste gas is led into the water granulated slag drying unit 13 through pipelines 7, 12. Here, the dampers 14-16 of the pipelines 11, 12, 17 are changed over by the change-over control panel 18 which selectively controls the hot stoves.

Filed: 1993-02-01
Abstract: PURPOSE:To early receive a command of a host computer by previously recording information of an SFP area in a DMA area, reading only the DMA area at the time of starting an apparatus, and deciding operating conditions. CONSTITUTION:This method for controlling a magneto-optic disk apparatus comprises the step of recording essential information of an SFP area in the same sector as that of DDS information of a DMA area when formatting a magneto-optic disk 12. When a formatted magneto-optic disk 12 is mounted, only the DMA area is read, operating conditions are decided, and a reception of a command from a host computer 2 is monitored. Accordingly, it is not necessary to read an SFP area at each time of starting a magneto-optic disk apparatus 1 as opposed to the prior art, a time required for initialization is shortened that much by its reading time. Thus, the apparatus 1 can early receive a command of the host computer after starting.
