Title: Pin diode
Inventor: WATARI YOSHIHIKO
IPC: H01L29/861
Filed: 1982-02-03
Abstract: PURPOSE:To obtain a diode having very small forward series resistance in a mass production scale with an extremely small structure by concentrically disposing a P<+> type region and an N<+> type region in an intrinsic layer when forming a PIN diode. CONSTITUTION:An N<+> type region 2 is concentrically diffused at a P<+> type region 3 as a center in an intrinsic N type semiconductor substrate 1 which exceeds 2,000OMEGAcm, and the entire surface is covered with a passivation film 4. Then, the prescribed hole is opened at the film 4, an electrode 5 is covered on the region 3, and an annular similar electrode 5 is covered on the region 4. In this manner, the thickness of the intrinsic layer and hence the distance t1 between the regions 2 and 3 can be reduced to smallest possible size by a photocomposing technique, and the design and manufacture of a diode having very small forward series resistance can be facilitated.

Title: Water heater capable of immediately delivering hot water
Inventor: TAKAYAMA MASAYOSHI
IPC: F24D17/00
Filed: 1987-01-26
Abstract: PURPOSE:To secure the maximum hot water delivery rate by employing a connecting pipe connected to a tap as a not water supply pipe by a constitution in which when hot water delivery is resumed, a valve device is actuated to open a circuit from a bypass line a connecting pipe so that hot water from a heat absorber can reach to the tap by way of both the hot water supply pipe and connecting pipe. CONSTITUTION:When a tap 2 is opened, a normally closed water flow switch 16 is opened, because a water flow is generated in a water line 14, to discontinue the electricity to a parallel circuit of a three-way valve 41 and a pump P. Hot water from a heat absorbing pipe 10 in a heat exchanger flows from a hot water pipe 11 and a connecting pipe 12 to the tap 2 from which hot water is delivered. When the tap 2 is closed, water ceases to flow in the water line 14 and the heat absorbing pipe 10 becomes closed. However, when the detection temperature at a thermistor S becomes lower than the set temperature, an output switch is closed to activate both the three- way valve 41 and pump P. The circuit is then opened to allow the combustion at a burner 3. Water in the closed circuit of the heat absorbing pipe 10, hot water supply pipe 11 and connecting pipe 12 is recirculated and heated so that it may be maintained always at a set temperature.

IPC: F23N5/24
Filed: 1992-01-31
Abstract: PURPOSE:To provide a gas leakage alarm capable of preventing the generation of an error alarm to be easily generated when an insecticide or the like containing LP gas is used in the vicinity of a gas sensor setting place. CONSTITUTION:An output signal V from an amplifier 2 for amplifying an output signal from a gas sensor 1 is led into a comparator 3. The comparator 3 compares the level of the input signal with a previously set alarm level V0, and when the level of the input signal exceeds the V0, sends an output signal. The output signal is applied to an alarm system 5 through a switch circuit 4. On the other hand, the output of the amplifier 2 is also led into a pattern analyzer 11 through an A/D converter 10. The pattern analyzer 11 analyzes the time changing rate pattern of the input signal, and when the analyzed pattern is approximated to a previously registered time changing rate pattern, applies an OFF control signal (j) to the circuit 4 for a fixed period.

Title: Rotational frequency sensor
Inventor: YAMADA HIROSHI
IPC: G01P3/488
Filed: 1990-01-26
Abstract: PURPOSE:To detect rotational frequency from a slow area up to a rapid area while suppressing an output voltage to a narrow range by providing the rotation al frequency sensor with coils for generating electromotive force by the rotation of the rotor and resistors element having a low resistance value. CONSTITUTION:When an output spindle 18 is rotated, the rotor 12 is rotated, electromotive force is generated from the coils 14, 15 following the rotation of the rotor 12 and voltages are respectively generated from both the ends of the resistors 22, 23. Since the resistance values of the resistors 22, 23 are low, changes in the output voltages of respective resistors 22, 23 can be suppressed to small values even if the rotor 12 is rotated from the low rotational area up to the high rotational area. When the resistance values of respective resistors 22, 23 are set up so that the level of the low rotational area can be detected, the rotational frequency from the low rotational area up to the high rotational area can be detected by a low level voltage. Since the output voltages of the resistors 22, 23 are detected, the rotational frequency of the rotor 12 at the time of forward rotation and reverse rotation can be detected.
