Title: Transmitting system of multifrequency signal
Inventor: YAMAMOTO MASAHIKO
IPC: H04Q11/04
Filed: 1980-05-06
Abstract: PURPOSE:To transmit a multifrequency signal, by digitizing every multifrequency signal corresponding to each code and connecting the output of said digitized signal to a channel at the prescribed incoming side of a digital time-division switch. CONSTITUTION:The analog signals of the generating circuits 1-A, B and C that produce the push-button signals 1-0 are converted into the digital codes through the coding circuits 11-1A...1C respectively. The digitized outputs of these coding circuits are connected to the incoming side channels IC1-ICA, -ICC of a digital time-division switch 200. Then the address information of a corresponding channel memory 201 is written into the address corresponding to the trunk of a call holding memory 202 from a control part 100 and with every digit. Thus the above-mentioned digital outputs are sent to a decoding circuit 21 and then decoded to the analog signals to be sent to the trunk.

Title: Magnetic-core saturated type position transducer
Inventor: SATOU HIROSHI
IPC: G01D5/20
Filed: 1979-05-15
Abstract: PURPOSE: To improve mass-producibility and durability while stabilizing characteristics by saturating a hollow magnetic core by a DC magnetic field source which slides in the hollow part of the hollow magnetic core.  
     CONSTITUTION: In the magnetic-core saturated position transducer with single permanent magnet 2 sliding in a couple of magnetic cores 1 and 1' wound with a couple of troidal windings 3 and 3', the magnetic circuit including permanent magnet 2 and the couple of magnetic cores 1 and 1' is closed and since the magnetic resistance is small and the permeance coefficient is high, much magnetic flux can be drawn from permanent magnet 2, so that the magnetic cores can be saturated by the weak permanent magnet. An offset to the DC output voltage of DC conversion part 11 is therefore eliminated easily and a response even to extremely-small sliding force is made because of small friction, so that an offset in terms of final displacement-to-DC voltage characteristics can nearly be eliminated.

Title: Shower unit
Inventor: UEDA YASUKIYO
IPC: F24D17/00
Filed: 1984-03-27
Abstract: PURPOSE:To improve the heat exchange efficiency of the shower unit by a method wherein the amount of heat discharged after a bather's taking a shower is transferred to water supplied to a hot water feeder by utilizing a characteristic peculiar to the shower in which hot water is discharged in a stabilized condition at the time of the bather's taking a shower. CONSTITUTION:The hot water feeder is of automatic temperature control type and constructed such that the hot water feeding temperature detected by a sensor 16 and the temperature set by a remote controller 17 are compared to each other by a controller 15 in the hot water feeder 7 so that the hot water feeding temperature is automatically controlled to coincide with the set temperature and a heat exchanger 18 is provided in a drain passage so that the amount of heat of the hot water discharged at the time of one's taking a shower is transferred to the water supplied to the hot water feeder. With the above structure, when a shower begins to be used, there is almost no discharge of hot water and the water supplied to the hot water feeder 7 is cold. Accordingly, the amount of consumption of heat by the hot water feeder 7 required for performing a supply of hot water of a suitable temperature does not change as compared to the conventional shower unit but when discharged hot water reaches the heat exchanger 18, the temperature of the supply water rises rapidly and as a result, the amount of consumption of heat by the hot water feeder 7 required for performing the supply of hot water of a suitable temperature reduces sharply automatically.

Title: Production of hydrogen
Inventor: NAKANISHI HIROSHI
IPC: C01B3/02
Filed: 1982-04-12
Abstract: PURPOSE:In the hybrid process using SO2, Br2 and water, photochemical reactions with a catalyst are carried out instead of electrolytic reactions to produce hydrogen with reduced energy consumption and simple facilities in no need of electric power. CONSTITUTION:The first step reaction of equation I thermochemically proceeds with ease using water, SO2 and Br2 obtained at the second and third step reactions. The sulfuric acid and HBr formed are separated by distillation and used in the second and third step processes. The second step reaction also proceeds thermochemically according to the equation II to give O2, one of the final products as well as water and SO2, as by-products, which are made to return to the first step process. The third step reaction decomposes HBr into H2 and Br2 with light energy in the presence of a catalyst acting in visible and/or ultraviolet region at room temperature such as a metal oxide and the Br2 is recycled to the first step to form a reaction cycle.

Abstract: A digital wristwatch with dual displays, one a liquid crystal display (LCD) for use in daylight or bright light and the other a light emitting diode (LED) display for use in dim light, is provided with three controlling push buttons (LED, Date and Set) for five display conditions and four setting conditions. With no button pressed, hours and minutes are displayed by the LCD elements. The LED button alone causes the LED elements to also display the hours and minutes for at least 1.5 seconds and the Date button alone causes the date to appear by the LCD, and if the Date push button is held over about 1.5 seconds the date will also appear on the LED display. The LED and Date buttons pressed together will cause the LCD elements to display the seconds, even after they have been released for "hands off" seconds display until either push button is again momentarily pressed. The Set button slews hours when pressed alone, and slews minutes and instantaneously zeros seconds when pressed together with LED, and slews the date when pressed together with the Date push button. Pressing all three will cause a complete reset of all counters.

Filed: 1985-03-26
Abstract: PURPOSE:To control the 'ON' voltage of a power transistor to an optimum value by adding an adjuster, a block diode, a compensation diode, etc., to a base current saving-type base drive circuit. CONSTITUTION:The collector potential of the power transistor TR 1 is inputted so that it can be negatively fed back to the adjuster 5 formed with a proportional integrating computing element through the block diode 6. A VCB setting voltage source 8 is provided between the base of the TR 1 and the compensation diode 7. Then a setting voltage across a collector and a base which uses the base of the TR 1 as a reference potential, is inputted as a setting signal to the adjuster 5 through the compensation diode 7 compensating a voltage drop in the normal direction of the diode 6. Thus an appropriate 'ON' voltage, that is, the voltage VCE across a collector and an emitter, can be available.
