Title: Thermo valve cartridge
Inventor: NISHIOKA AKIRA
IPC: F16K31/68
Filed: 1995-03-02
Abstract: PURPOSE: To prevent the inflow of hot water from a hot water passage by the pressure of water flowing in a guide section from being checked by projecting a ring shaped guide section which is faced at an interval to the inside of a valve main body while being faced to a hot water passage, out of an opening peripheral section of a valve seat collar. CONSTITUTION: Hot water flowing in the inside from the hot water passage 14 of a combination faucet is guided to the valve main body 61 of a valve with a thermostat provided for a thermovalve cartridge along a guide section 4a while being not affected by water pressure, and is mixed with water. When the temperature of mixed water is raised, for example, up to a temperature higher than a set temperature, the temperature is sensed by a thermo element 63, thermo-wax is thereby expanded, a piston 62 is pushed out, and the valve main body 61 is thereby moved to the left in the figure.  As a result, the hot water passage 41 between the valve main body 61 and a valve seat collar 4, is narrowed, and on the other hand, since a water supply passage 81 interspaced from a valve seat 8 is widened, mixed water is lowered in temperature, and the temperature of mixed water is thereby automatically adjusted to the specified temperature.

Title: Electronic time-piece with sound memory function
Inventor: MIYAZAKI HAJIME
IPC: G11C27/00
Filed: 1983-04-19
Abstract: PURPOSE:To make it possible to perform re-recording only by one external switch manipulation when recording is started over again from the begining after a recording mistake, by providing a recording key control circuit. CONSTITUTION:When a switch REC is inputted, an REC signal is outputted to an automatic start circuit 9 from a recording key control circuit 11 while the automatic start circuit 9 is brought to an operative state and a recording stand- by state is made. Therefore, when a sound is inputted in this state, an AST (automatic start) signal is outputted to start recording. At this time, the automatic start circuit 9 comes to a non-operative state. When the switch REC is again inputted in this recording state, the recording key control apparatus 11 outputs the REC signal to the automatic start circuit 9 and outputs an RST (reset) signal to a recording part 7. The automatic start circuit 9 is again brought to an operational state when the REC signal is inputted. In this case, when the RST signal is inputted to the recording part 7, a start address is initialized and recording can be performed from the beginning of recording memory.

Title: Deciding method for commercial alternating current frequency of apparatus
Inventor: TANAKA NORIO
IPC: G01R23/15
Filed: 1979-06-06
Abstract: PURPOSE: To ensure the steady automatic decision in spite of the variation of the ambient temperature for the apparatus which uses the microcomputer for the control purpose, by giving the correction to the fluctuation of the oscillation frequency caused by the ambient temperature and then giving the measurement and then the decision to the cycle based on the oscillation clock.  
     CONSTITUTION: Microcomputer 1 operates all in synchronization with the signal supplied from clock oscillation circuit 11. The timer is started at the moment when reference frequency signal 2 is supplied to computer 1, and the clocking is continued until the next pulse is supplied. Then the comparison is given between the clocking value and the reference value which is set previously in order to give the decision to the frequency of signal 2. Here the reference value uses the oscillation frequency of circuit 11 in computer 1, and thus the correction is given to the fluctuation caused by the ambient temperature via the signal of temperature sensor 7. Thus the correction is given to the reference value with readout of the ambient temperature, and then the measurement is carried out based on the oscillation clock of computer 1. As a result, the steady automatic decision is possible in spite of the variation of the ambient temperature.
