Title: Hot water washing device
Inventor: NAKAMURA MASAMI
IPC: E03D9/08
Filed: 1995-06-27
Abstract: PURPOSE: To provide a hot water washing device by which stable jet hot water can be obtained with a small and inexpensive device by contriving the device in such a way that when the temperature of mixed water obtained by mixing up the water from a cold water inflow port with the water from a high-temperature water inflow port is detected by a shape-memory alloy spring, the open/close area of the inflow ports are regulated by a plunger in the balance of the load of the alloy spring and that of a bias spring. CONSTITUTION: The temperature adjusting knob 17 is set to a desired temperature. Then, a washing switch is operated to open an solenoid valve, so that cold water flows in through a cold-water inflow port 6 of a mixing valve 3, and high-temperature water flows in through a high-temperature inflow port 7 through a hot water tank. Then, the mixed water flows out from a mixed water outflow port 8 through the hollow part of a plunger 11 or through the detecting part 20 where the mixing part 19 and a shape memory alloy spring 9 are positioned. At that time, the spring 9 detects the temperature and a spring load corresponding to the detected temperature is produced. Thereby, the load is increased at a high temperature to push the plunger 11, so that the area in the inflow port 6 is increased, and the area in the inflow port 7 is decreased.  As a result, the quantity of cold water is increased, and the quantity of high-temperature water is decreased. Thus, the temperature of jet hot water can be stabilized for enhancing comfortability.

Title: Instrument for measuring concentration of o2 and combustible gas in exhaust gas
Inventor: MAEDA MASATO
IPC: G01N27/409
Filed: 1986-07-08
Abstract: PURPOSE:To measure a combustible gas and O2 with high sensitivity by using a detector by inserting a zirconia solid electrolyte sensor provided with porous electrodes on the inside and outside surfaces directly into a flue in which a combustion gas flows. CONSTITUTION:The zirconia solid electrolyte sensor 3 of a test tube type is provided in a casing 1 which is directly inserted into the flue from a wall 2. The inside electrode 4 in contact with a measuring gas G and the outside reference electrode 5 in contact with a reference gas are provided to the inside and outside surfaces of the sensor 3. The electrode 4 is divided to the two electrodes 4a, 4b. The electrode 4a is coated with a film 8 having the high catalytic power to oxidize most of the combustible gas. The electrode 4b is coated with a film 9 playing the role of almost exclusively preventing the exfoliation of the platinum electrode. The potential difference between the electrode 4a and the electrode 5 indicates the concn. of the O2 after the combustible gas makes complete combustion. On the other hand, the electrode 4b has the low catalytic power and the combustible gas decreases the electromotive force by acting directly on the O2 in the zirconia solid electrolyte; therefore, the difference in the electromotive force between the electrodes 4a and 5 and the electromotive force between the electrodes 4b and 5 indicates the concn. of the combustible gas.

Title: Rotary head type video signal reproducing device
Inventor: YOSHIMURA KATSUJI
IPC: H04N9/896
Filed: 1986-07-10
Abstract: PURPOSE:To attain a satisfactory reproduction irrespective of the carrying speed of a tape shape recording medium by changing the rotating speed of a rotary head according to the longitudinal carrying speed of the tape shape recording medium. CONSTITUTION:A clock signal outputted from a switch 24 has a frequency corresponding to the rotating speed of the rotary head. Therefore, during a period when the rotary head traces on the tape, the video signal of one field can be constantly read. Accordingly the reproduced signal of the rotary head constantly coincides in a timing with the reading signal of a field memory 6. Since a pseudo-vertical synchronizing pulse is formed by using this clock, the pseudo-vertical synchronizing pulse completely synchronizing with the video signal read from the field memory 6 is obtained. Thereby, irrespective of the running speed of the tape shape recording medium, the relative speed of the rotary head and the tape shape recording medium is made constant and the extremely satisfactory reproduced video signal is obtained.

Abstract: PURPOSE:To dispense with a detection condenser for a tube voltage potential divider as well as to make the number of parts items reducible, by dividing and connecting a condenser sufficiently smoothing the tube voltage so as to divide voltage of the tube voltage. CONSTITUTION:Condensers 31-34 and resistors 35-38 form a tube voltage potential divider. At an A point, a capacity potential dividing ratio by condensers 33 and 34 is almost equal to a resistance potential dividing ratio by resistors 37 and 38, and at a B point, the capacity potential dividing ratio by condensers 33 and 34 is almost equal to resistance potential dividing ratio by resistors 37 and 38. In this connection, the condenser capacity required for smoothing tube voltage so sufficient enough is set to C5 so that it is expressible with an equation of C5=C31C32/(2C32+2C31)...(6). Therefore, the capacity potential dividing ratio and the resistance potential dividing ratio required for tube voltage detection are selected, and when a necessary capacity value for smoothness is found out of this equation (6), these condensers 31-34 secure a sufficient smoothing effect and thus the tube voltage is detectable. The detected tube voltage signal compares a tube voltage setting value signal S3 with a tube voltage detecting value signal S1 through a first detection circuit 19, a second detection circuit 20 and an operational circuit 21, therefore it will do that the tube voltage is merely controlled so as to make the error smaller.
