Abstract: PURPOSE:To make a uniform air-fuel mixture formable by installing a temperature control means which controls a pipe inlet so as to cause a heating tubule facing to the tip of a fuel injection valve and its inner surface temperature to become a Leidenfrost's point all the time. CONSTITUTION:A fuel injection valve 1 determines an injection time on the basis of duty control according to an engine state, and injection fuel out of this injection valve 1 is led into a spot proximate to an intake valve of an engine passing through the inside of a heating tubule 2. An inner surface of the heating tubule 2 in this case is controlled so as to become a Leidenfrost's point all the time by a control circuit 12 even if a driving condition of the engine is changed. Concretely, inner surface pressure of the heating tubule 2 is detected on the basis of the engine driving condition at time of engine driving, and on the basis of this detected value, the control circuit 12 operates the present Leidenfrost's point, emitting a command to a power source 4 so as to cause a current conformed to this operated value to flow into a heater 3. Thus, the inner surface of the heating tubule 2 is always keepable in a temperature state for the Leidenfrost's point.

Title: Data multiplexing system
Inventor: KANAZAWA MASARU
IPC: H04N7/08
Filed: 1988-12-21
Abstract: PURPOSE:To increase addition information quantity to be multiplexed by superimposing a guard band just before the synchronizing signal of a television signal and multiplexing the additional information between the guard band and a video signal. CONSTITUTION:A guard band 12 is superimposed so as to be overlapped to the falling of a horizontal synchronizing signal and the level of the guard band is 100% of the video signal. Thus, since the inclination of falling is made almost three times in comparison with a case that the guard band is not superimposed, the jitter of the horizontal synchronizing signal due to the leak of data, which are multiplexed between the guard band 12 and video signal, to a surrounding part is reduced to almost 1/3. Thus, the additional information to be multiplexed can be increased.

Title: Hot-water heater
Inventor: KAWAUCHI KAZUYA
IPC: F24D3/00
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To permit the optimum freeze prevention at freeze preventing operation by a method wherein a valve is closed and the opening operation of the valve is prohibited when remaining water in a bathtub is detected upon the freeze preventing operation, effected by conducting hot-water to flow in a pipeline for hot-water heating system. SOLUTION: A freeze prevention control means 65 judges whether freeze preventing operation of the side of a bathtub is necessary or not. A remaining water detecting means 64 detects the existence of remaining water by discriminating whether a water flow switch is put ON or not by driving a circulation pump 44 for reheating. When the water flow switch is turned on within a predetermined period of time after driving the circulation pump 44 for reheating, it is judged that remaining water exists in the bathtub and the freeze preventing operation of the side of bathtub is effected utilizing the remaining water.  When a thermal valve for heating 38 is closed, the opening operation of the same is effected, then, bath water, circulating through a circulating flow passage for bathtub water reheating, is heated by the heat exchanger for bathtub water reheating for 10min, for example, to prevent freezing by increasing the temperature. After the freeze preventing operation for a predetermined period of time, the circulation pump 44 is stopped and the thermal valve 38 for heating is closed to finish the freeze preventing operation.

Title: Bias circuit for apd
Inventor: KONO TOSHIBUMI
IPC: H04B10/564
Filed: 1987-12-21
Abstract: PURPOSE:To quicken a response for the switching on/off of power source or a sudden variation of an optical input by controlling a DC conversion circuit by ah amplification circuit so that a current to flow in an APD(avalanche photodiode) comes constant. CONSTITUTION:The current to flow in the APD 2 is converted into a voltage by the resistor R1 of a current detection circuit 3. The amplification circuit 4 organizes an inverting amplification circuit by the resistors R2, R3 and an operational amplifier OP1, and the DC conversion circuit 1 is controlled so that the output of the current detection circuit 3 coincides always with a reference voltage. Namely, the current to flow in the APD 2 is kept constant regardless of the magnitude of the optical input. The signal component of the APD 2 is transmitted to the amplification circuit including the operational amplifier OP2 of a next stage through a coupling condenser 5. Thus, because the current to flow in the APD can be made constant by controlling the bias voltage of the APD without using an F-AGC to control the multiplication factor of the APD, the response can be quickened.
