Abstract: PROBLEM TO BE SOLVED: To prevent arising of a problem on injection of high temperature hot water by providing a reheating of bathtub water blocking part to block reheating of bathtub water until a bathtub is filled with hot water up to a set water level after the starting of filling with hot water. SOLUTION: A control device 40 is provided with a reheating of bathtub water blocking part and a combustion control part. The reheating of bathtub water blocking part inputs movement information of a combustion control part and starts an output of a signal for blocking of reheating of bathtub water to the combustion control part when an apparatus starts operation to fill with hot water based on the information. The reheating of bathtub water blocking part continuously outputs a reheating of bathtub water blocking signal until a water level in a bathtub 22 reaches a set water level set by a bath water level set means 43. When, based on information of a combustion control part, it is detected that filling with hot water is completed, output of the reheating of bathtub water blocking signal is stopped.  The combustion control part effects no reheating of bathtub water while the reheating of bathtub water blocking signal is received, namely, during filling with hot water.

Title: Driving circuit for stepping motor
Inventor: URITA SEIICHI
IPC: H02P8/08
Filed: 1981-03-31
Abstract: PURPOSE:To reduce the noise of a stepping motor at the starting time by starting always the motor from the specific step. CONSTITUTION:When a start pulse 8 is fed from a start pulse generator 2 prior to a drive pulse, this pulse is outputted from an NAND gate 7 in synchronization with a clock supplied to a flip-flop 6, is inputted through integrators (c), (r) to an excitation sequence generator 3 to reset a counter 4. Thus, the pulse sets so that the step sequence of an excitation sequency generator 3 starts from zero step. Then, a pulse control circuit 1 outputs a drive pulse 9, a counter counts it, and the output is decoded by a decoder 5, and a stepping motor is started by the excitation pulse of the zero step. In this manner, since the excitation pulse of the zero step is always outputted at the starting time, the turning direction at the starting time can be determined, thereby suppressing the resonance phenomenon of the stepping motor.

Title: Method and instrument for measuring connection loss of optical fiber

IPC: G01M11/02
Filed: 1986-03-04
Abstract: PURPOSE:To measure the connection loss of an optical fiber with high accuracy by observing the waveform of a back scattered wave with two light waves having different wavelengths for one optical fiber to be measured and then performing arithmetic operation. CONSTITUTION:A pulse generator 2 generates a pulse signal synchronized with a timing signal from a signal processing part 1 and a switch 3 supplies this pulse signal to one of light sources 4 and 5. The light sources 4 and 5 emit pulse light beams with wavelengths lambda1 and lambda2 respectively and those pulse light beams are incident on the optical fiber 8 to be measured which consists of optical fibers f1 and f2 connected at a connection point (j) through the optical directional coupler 7, etc. Consequently, part of Rayleigh scattered light generated in the fiber 8 returns to an incidence terminal as back scattered light and is incident on a photodetector 9 through the coupler 7, and the output of the photodetector 9 is amplified 10 adn supplied to a processing part 1. The processing part 1 displays the waveform of the back scattered wave, stores step quantities alphabs(lambda1) and alphabs(lambda2) at a point (j) which are obtained from the back scattered light waveform when a measurement is taken with the pulse light beams from the light sources 4 and 5, and calculate the quantity of connection loss at the time of the wavelength lambda1 from an equation (klambda: coefficient of wavelength dependency), thereby displaying it on a CRT.

Title: Variable length code converter
Inventor: MIKAMI FUMIYUKI
IPC: H03M7/14
Filed: 1988-03-01
Abstract: PURPOSE:To reduce the number of ROMs by utilizing the fact that the number of basic code words of (n) bits is less than that of code words possible to be represented in (n) bits and separating a processing to temporary encoding and final encoding in an encoder for a variable runlength limited(RLL) code. CONSTITUTION:A (4, 19, 2, 5, 6) code in which the number of run of '0' of a binary code word string with basic data word length (m)=2, basic code word length n=5, the number of code word length rmax=6, and connecting code words after conversion is limited to a value >=4 and <=19 is taken as a sample. The number of basic code words is remarkably small than that of binary codes represented in the (n) bits that is the basic code word length. It is because that the number of run of '0' of the binary code word string is limited at a value over 4 and less than 19. Assuming the number of basic code word patterns as (p) and (q) as the minimum integer which becomes p<2, it is possible to designate either the basic code word patterns by (q) bits uniquely. The temporal code of (q) bits is outputted first corresponding to an input data word, and next, the final encoding to the basic code word of (n) bits designated by the (q) bits is performed, thereby, the capacity of the ROM required for the temporal encoding can be reduced by q/n.
