IPC: H01C7/00
Filed: 1983-06-20
Abstract: PURPOSE:To provide a long-life low-cost high-temperature heating element usable at a high temperature without causing the evaporation of Cr component, having excellent heat-deformation resistance and degradation resistance, by forming the terminal part having a specific composition integrally with the heat-generating part having different composition. CONSTITUTION:The objective high-temperature heating element is manufactured by forming the terminal part made of the material of formula I (x is 0.03-0.4) integrally with the heat-generating part made of the material of formula II (x is defined above; y is 0.03-0.4). The conventional lanthanum-chromite heater has low practical value at a high temperature because of its deformation or degradation. Furthermore, since the Cr component is evaporated at high temperature, the problem of contamination of the object to be heated and the deformation or degradation, etc. of the heating element by the decrease in the Cr content occurred. The above defects are eliminated in the present heating element, and consequently, the element can be used at a high temperature for a long period without causing the evaporation of the Cr component, and can be manufactured at a low cost.

Title: Misfire detector for gasoline engine
Inventor: MIYATA SHIGERU
IPC: F02D45/00
Filed: 1993-05-12
Abstract: PURPOSE:To provide a misfire detector for surely detecting misfire without being affected by the sensitivity of a sensor even in the instantaneous break-down at the time of the misfire of an engine. CONSTITUTION:Sensor output is held by a sample hold circuit 31 for a specific time period directly after spark discharging voltage is generated, and the output multiplied by a constant is determined as a second reference value. When the sensor output exceeds the second reference value, the sensor output is charged in a charging/ discharging circuit 34, and the voltage and a specific voltage are compared with one another by a comparison circuit 36. Although the sensor output voltage charged at the time of ignition is low while the high-level continuation period of the comparison circuit 36 is short, the sensor output voltage at the time of misfire is high, and the high-level continuation time of the comparison circuit 36 becomes longer. Misfire is detected by a misfire judgement part 24 by means of the logical sum of the sensor output voltage and the output signal of a comparison circuit 27 which maintains high-level until the sensor output is reduced to one third of the peak voltage after spark discharging is completed. Since the voltage held by the sample hold 31 is determined according to the specification of an ignition system, there is no effect of the sensitivity of the sensor.

Title: Hot water supplying device
Inventor: NAGAOKA YUKIO
IPC: F24D17/00
Filed: 1994-05-25
Abstract: PURPOSE:To improve the hot water temperature controllability and to obtain a sufficient bias ratio, by regulating the position of a mixing valve body by an electromagnetic force generator, so as to control the mixing hot water temperature. CONSTITUTION:When a current does not flow to the coil 29 of an electromagnetic force generator 31 of a mixing valve device 12, an elastic body 32 energizes a movable iron core 27 to the lower side, a water valve body 26a of a mixing valve body 26 is fully opened, and a hot water valve body 26b is fully closed. When the current is fed to the coil 29, a sucking force is operated between a fixed iron core 30 and the movable iron core 27, and the movable iron core 27 moves to the position to balance the elastic body 32. That is, the position of the mixing valve body 26 can be regulated continuously by the current amount of the coil 29. The water pressure, the hot water pressure, and the mixing pressure are operated to a water flow-in passage 21, a hot water flow-in passage 22, and a mixing hot water passage 23, of the mixing valve body 26 respectively, but since the pressure receiving areas of the water valve body 26a, the hot water valve body 26b, and a partition wall body 28 are equal, they negate each other to obtain a balance. Consequently, the position of the mixing valve body 26 can be determined by only an electromagnetic force operated to the elastic body 32 and the movable iron core 27.

Abstract: PURPOSE:To uniformize a light quantity distribution in an illuminated area on a diffusing plate surface being an illuminated surface and to improve illumination efficiency by providing a light-shielding member, which shields from a harmful luminous flux, near a glass tube which composes a light source part. CONSTITUTION:The light-shielding members 9 and 10, both of which are provided near the glass tube 2 composing the light source A, shield from luminous fluxes, the so-called harmful luminous fluxes L1 and L2, which are reflected from a reflecting mirror 3, pass through the peripheral area of the glass tube 2 of the light source A without being transmitted through the light source A, and travel toward a condenser lens 4. Therefore, the nonuniformity of the light quantity distribution on the surface of the diffusing plate 6, caused by the harmful luminous fluxes L1 and L2, can be removed. Thus, the light quantity distribution in the illuminated area on the surface of the diffusing plate 6 can be uniformized, and illumination efficiency can be also improved.
