Title: Binary-decimal converting circuit
Inventor: SATOU MASASHI
IPC: G06F7/00
Filed: 1983-03-16
Abstract: PURPOSE:To simplify a constitution and to attain high-speed processing by performing a binary-decimal operation just with a decimal total addition. CONSTITUTION:A binary input to be converted with a command of a controller 4 is loaded to a shift register 1, and at the same time a temporary memory register 2 is reset. While the output 34 of a decimal adder 3 delivers the value obtained by doubling the contents of the register 2 and the value obtained by adding the present highest bits of the register 1. Therefore the first output D0 of the adder 3 is set as D0=Dn (Dn: the highest bit of the register 1). Then the D0 is loaded to the register 2, and at the same time the register 1 is shifted toward an MSB by a bit. As a result, the next output D1 is set as D1=bnX2+bn-1. Thus an output Dn is obtained through conversion of a binary number into a decimal number by repeating the above-mentioned operations by a frequency equal to the bit number (n) of the binary input.

Title: Hot water supplying device
Inventor: OZAKI YUKINORI
IPC: F24H1/46
Filed: 1990-02-23
Abstract: PURPOSE:To enable a user to take comfortable bathing in terms of temperature regardless of a season by a method wherein during filling of a bath tub with hot water, the temperature of hot water fed to the bath tub is changed according to a detecting temperature from a temperature detector, and additional burning is effected according to a signal from a bath detecting sensor. CONSTITUTION:By depressing a hot water filling button, a solenoid valve is opened and hot water heat-exchanged by a heat-exchanger 15 for a hot water feed through combustion of a burner 16 is fed through connecting pipes 18 and 19 to a bath tub 13. In this case, when an open air temperature detected by a thermistor 26 is, for example, 0 deg.C, hot water is fed at a feed hot water temperature of 40 deg.C. When a user enters the bath tub 13, hot water is stored in the bath tub 13 at a hot water temperature decreased to 36 deg.C due to cooling. A water level in the bath tub during the feed of hot water is increased with the lapse of a time, and filling with hot water is completed at a point of time when hot water quantity attains 200. Since, in this state, an open air temperature when a user takes bathing is 0 deg.C, especially when he comes home from an outdoor place, the surface temperatures of the hand and the legs of the user are low. Therefore, when this user takes a bath by using hot water with a temperature of 36 deg.C, temperature is adjusted to just a proper value. Since a change in a water level is sharply increased due to a bath, the change in a water level is detected, additional burning is effected by an additional burning means, and when temperature is increased to a specified value, automatic shut-off takes place.
