Title: Electric instant water heater
Inventor: KAMIMURA MASAHITO
IPC: F24H1/10
Filed: 1992-11-25
Abstract: PURPOSE:To obtain hot water with an adequate temperature by heating incoming water by electricity which is suitable for the flow rate by a method wherein water at a flow rate which is previously set by a flow rate adjusting valve is fed in a tank, and at the same time, power is connected to a heater by a current carrying rate which is previously set by a volume switch of a control circuit. CONSTITUTION:When an opening/closing switch 9 is close-operated, a shut-off valve is opened, and water is fed to a tank 1 from an incoming water pipe 3 through a flow rate adjusting valve 8 and water pressure detector 7. By this water feeding, the water pressure detector 7 operates, and a pressure switch 6 is closed, and power is connected to a heater 2 by a current carrying rate which is set by a volume switch 12, and the water which is fed to the tank 1 is heated and made to be hot water. In this case, the adequate temperature of the hot water which flows out from a shower head 4 is obtained by the electricity of the heater 2, the flow rate of the fed water, and water temperature. Therefore, if the power of the heater 2 is set by previously setting the current carrying rate of the volume switch depending on the season, and at the same time, the flow rate is previously set by the flow rate adjusting valve 8, hot water with an adequate temperature can be always obtained.

IPC: H01L21/302
Filed: 1994-12-19
Abstract: PURPOSE: To manufacture an integrated circuit having a specific line width of less than one micron by forming a self-aligned contact by using an Si3 N4 insulating film having a reflection preventing effect. CONSTITUTION: A hole is opened by etching through a nitride layer 214 at a position where a contact to a fist polysilicon layer 210/212 deposited on a field oxide film 202 is formed. After an oxide film 216 is grown, Si3 N4 is conformably deposited thereon and is anisotropically etched by an SF6 +CF4 etching material while detecting edges to form a side wall spacer 220. A substance having a BPSG232 is deposited on an undoped silica glass 230 and then is etched by an oxide etching material having selectivity for Si3 N4 . This can control the line width below 0.5 micron.

Title: Offset adjusting device of hall current transformer
Inventor: FUNAMOTO KOUJI
IPC: G01R19/00
Filed: 1990-11-20
Abstract: PURPOSE:To automatically adjust an offset to zero by starting the operation of a change signal generating means when a current to be detected is zero, and stopping the operation when a zero detecting means detects zero. CONSTITUTION:When a breaker 4 is opened, a start contact 22 is closed and an operation instruction is given to an integrator 24 via an instructing circuit 23. Therefore, the integrator 24 increases its output in accordance with the preset changing rate with time. If a Hall device 10 has an offset, the offset is amplified at 11 and input to an adder 12. Since the change signal is input also to the adder 12 from the integrator 24, both signals cancel each other. A zero output is detected by a comparator 21 when the output of the adder 12 becomes zero, and a stopping instruction is output to the integrator 24 through the circuit 23. As a result, the integrator 24 continues to output the value cancelling the offset. Accordingly, the adder 12 outputs a correct voltage signal corresponding to the current generated when the breaker 4 is closed. If the breaker 4 is opened, the offset is corrected again.

Filed: 1990-11-19
Abstract: PURPOSE:To achieve a smaller capacity of a capacitor by allowing a base current of a transistor to flow in an emitter follower circuit as buffer of a capacitor for holding a peak value only when it does to a following stage. CONSTITUTION:Transistors QP4 and QP5 are provided to turn ON or OFF a collector current of an emitter follower circuit for buffering a holding capacitor. In this case, when an output control signal 01 is a high voltage, the transistors QP4 and QP5 are turned ON and currents of constant current sources Iap and Ibp flow as collector currents of transistors QP1 and QP2 respectively to operated the emitter follower circuit, so that a voltage is outputted to a signal output terminal 2 corresponding to a peak value within time indicated as section A in a timing chart. In addition, when the output control signal 01 is a low voltage, the transistor QP4 is turned OFF and no collector current of the transistor QP1 flows. Thus, the charging of an electric charge of a capacitor CP1 will not occur by a base current of the transistor QP1 thereby achieving a smaller capacity of the capacitor.

Title: Input filter circuit for electronic tuner
Inventor: MASUDA SHIGETO
IPC: H04N5/44
Filed: 1989-12-05
Abstract: PURPOSE:To prevent intermodulation interference in an RF amplifier or a mixer circuit, etc., in a poststage by passing an input signal through the selected band pass filter of a comparatively narrow band. CONSTITUTION:When a channel within the bands of the band pass filters BPF1 to 3 is selected, a current is flowed from a band switching control circuit 10 to the BPF1 to 3 through a corresponding terminal 12, a coil L1, a diode D1, and a resistor R1, and a PIN diode D1 is turned ON. Similarly, the current flows through the route of the coil L2, the diode D2, and the resistor R2, as well and the PIN diode D2 is turned ON. The band switching control circuit 10 does not supply the current to other terminals 13, 14, and the PIN diodes D3, D4, D5, D6 are left OFF. Accordingly, the signal inputted from the terminal 1 containing many channels passes through only the BPF1 to 3, and only the channels within their passing bands are outputted to an output terminal 15. Thus, thereafter, the channel selection of less intermodulation interference can be executed.
