Title: Spark plug of internal combustion engine
Inventor: SUGIMOTO MAKOTO
IPC: H01T13/14
Filed: 1990-03-08
Abstract: PURPOSE:To prevent a treeing deterioration and a reduction of insulation by covering the surface of an insulator where the insulator and a main body metal approach with the oxide membrane of a specific thickness of nitride ceramics to compose the insulator itself. CONSTITUTION:This spark plug is composed of an insulator 2 which holds an ignition electrode 3 at the tip and consists of a nitride ceramics, and a main body metal 4 furnishing an outside electrode 5 arranged at the position opposite to the ignition electrode 3 held in the insulator 2. And the surface 6 of the insulator 2 where the clearance between the main body metal 4 is narrow less than 2mm is covered by an oxide membrane 7 of the thickness 10 to 70mum, which is made by oxidizing the nitride ceramics to compose the insulator 2 itself. As a result, even though corona discharge is generated owing to an electric field concentration at the surface 6 where the insulator 2 and the main body metal 4 approached by the spark discharge, and a dissolution reaction of the insulator 2 itself is generated, production and accumulation of metal following the dissolution reaction can be prevented. Consequently, generation of a treeing deterioration which reduces the insulation of the insulator can be suppressed.

Title: Hot water feeder and control method thereof
IPC: G05B11/32
Filed: 1992-03-13
Abstract: PURPOSE:To reduce the generation of noise through uniformization of quantity of heat to a hot water feeder regardless of a heating value of fuel gas by a method wherein when a given feedforward value exceeds maximum capacity of a hot water feeder, a water quantity is throttled so that a set value is obtained by means of maximum capacity of the hot water feeder. CONSTITUTION:An inflow water temperature detector, a feed hot water detector, a water quantity detector, and a water quantity control valve are disposed in a water passage passing a heat-exchanger. Meanwhile, a fuel flow rate regulating valve, a blower, and a blower airflow regulator are disposed in a fuel gas passage running to a burner. Further, a temperature setter to set a feed hot water temperature and a control circuit are disposed. In this case, an airflow is increased with the increase of a fuel amount until an airflow attains a specified value, and when it exceeds a specified value, a feed forward value at which an airflow is kept at an constant value is set based on a set temperature, an inflow water temperature, and a quantity of water. When the feed forward value exceeds maximum capacity of a hot water feeder, the quantity of water is throttled until a set temperature is obtained with maximum capacity of the hot water feeder.

Title: Dichroic mirror
Inventor: MURAYAMA YOICHI
IPC: F21V7/22
Filed: 1990-03-08
Abstract: PURPOSE:To obviate the generation of clouding and peeling and the deterioration of spectral characteristics in spite of long-term use by forming multilayered films on a substrate surface and then providing a protective film in which Si and SiOx (where x is 0<x<=2) prepared by vapor deposition of metallic silicon coexist. CONSTITUTION:The multilayered films 4 are formed on the inside surface of the curved part 2 of the substrate 1 which consists of glass, etc., and is formed to a cup shape. Further, the protective film 5 is formed thereon. The multilayered films 4 are formed by alternately laminating the films of ZnS and the films of MgF2 so as to obtain desired spectral characteristics. The protective film 5 is deposited by evaporation thereon to the state that the SiO and SiO2 or SiOx (0<x<=2) coexist, by which the protective film 5 is formed. The protective film 5 is oxidized by being exposed to the atm. and the oxidation of the Si progresses to the SiO and SiO2 but it takes time for the entire part of the protective film to turn to the SiO2. The function to protect the multilayered films 4 is thus maintained even if a lamp of a high output and long life is used.

Consequently, an inner frame 25 supported by a shaft 22 comes to be moved upward. Thus, a cassette 1 stored in the inner frame is detached completely from a positioning pin 28.

An organizational dither processing part 21 applies the Organizational dither method to areas other than edge areas to make noise and outlines inconspicuous in uniform gradation parts. A conditional random dither processing part 22 applies the conditional random dither method to edge areas to improve the reproducibility of edge areas.

Title: Semiconductor relay circuit
Inventor: TERASAWA TOMIZO
IPC: H03K17/04
Filed: 1986-03-14
Abstract: PURPOSE:To realize a semiconductor relay subject to high speed switching control by using complementary signals as input signals, using one signal as a gate drive signal of an output MOSFET and employing the other as a gate- source storage charge discharging signal. CONSTITUTION:When an input electric signal is given between input terminals 1 and 2, a photovoltaic element 6 generates a voltage. In this case, a light emitting 5 is not lighted and a photovoltaic element 9 generates no voltage. Thus, the 2nd MOSFET pair 8 is turned off. When a potential across the element 6 gets higher, an output MOSFET 10 is turned on. When the voltage is higher, the voltage exceeds a threshold value of the 1st MOSFET pair 7, the impedance of the 1st MOSFET pair 7 is lowered to discharge the 2nd MOSFET pair 8 and the photovoltaic element 9. When the input signal is lost, the element 5 is lighted and the element 9 generates a voltage to the turn on the 2nd MOSFET pair 8 thereby discharging the stored charge of the output MOSFET 10.
