Title: Diesel engine with auxiliary injection means
Inventor: TOKORO MASAMI
IPC: F02B3/06
Filed: 1984-03-05
Abstract: PURPOSE:To reduce emission of black smoke and to facilitate control of fuel injection, by advancing the ignition timing by keeping the fuel pressure of an auxiliary injection valve at a constant level, and controlling the auxiliary fuel injection valve according to the operational conditions of an engine. CONSTITUTION:A pulse signal having a frequency proportional to the engine speed and the engine load detected respectively by an engine-speed sensor D1 and a throttle lever opening sensor D2 is applied to a control unit 46, and a control signal S is applied to an electromagnetic injection valve 20 on the basis of said pulse signal. When the opening of a throttle lever becomes greater than a predetermined angle with increasing of the engine load, the injection period is so controlled that fuel is injected from the injection valve 20 at a predetermined rate (10-20%) to the total injection quantity of fuel according to the engine speed. Thus, since pre-flaming reaction is caused before main fuel ejected from a main injection valve 14 is ignited and the ignition of fuel is advanced, emission of black smoke is reduced. Further, since injection of fuel into an intake pipe is effected only at the time of high-load operation of an engine, increasing of HC contained in the exhaust gas is prevented.

Title: Closed magnetic circuit type ignition coil
Inventor: ASAKURA HIDEO
IPC: H01F38/12
Filed: 1989-02-22
Abstract: PURPOSE:To reduce noise of specific frequency band by regulating the characteristics of the primary and secondary windings of the coil to set a leakage inductance to a specific value or more. CONSTITUTION:A secondary winding A2 of an ignition coil A is connected to an ignition plug B, and a primary current of a primary winding A1 connected to a DC power source C is interrupted by an igniter D to measure noise. A noise current probe E is set to a primary circuit to measure a noise current of the primary circuit side by a field intensity meter F. If a leakage inductance is 0.7mH or more, noise is reduced in a range over 150-350kHz of frequency, and remarkably decreased particularly in a range of 270-350kHz. Thus, the leakage inductance is set to 0.7mH or more to reduce a noise of frequency band of several hundreds or less kHz.

Title: Gate monitor
Inventor: ISHIBASHI MITSUO
IPC: G01T1/169
Filed: 1993-03-03
Abstract: PURPOSE:To allow monitoring of radioactive contamination for a person regardless of the height by providing a vertical foot driving means. CONSTITUTION:When a person A to be monitored enters into a pass gate 2, a gate monitor controller 14 controls a vertical head drive section 5 to lower a head radiation detector 3-1. When the detector 3-1 reaches a point separated by a predetermined distance L from the head part, the detector 3-1 is stopped and detectors 3-1-3-14 detect radiation under tall height mode and the monitor 14 monitors radioactive contamination of the person A. When the monitor 3-1 can not reach the point before it reaches the lower limit point, the monitor 14 decides a short height mode representative of a height shorter than a limit level. Consequently, a vertical foot drive section 11 is driven to elevate a foot detector supporting section 13. When the head part of the person A reaches a point separated by the distance L from the sensor 3-1, the monitor 14 stops the supporting section 13 and the detectors 3-1-3-14 detect dose on the body surface of the person A thus monitoring radioactive contamination.

Filed: 1988-02-25
Abstract: PURPOSE:To obtain a wafer characterized by stable activating rate and less dispersion, by implanting arsenic ions in the surface of semi-insulating gallium arsenide single crystal wafer, forming an insulating film comprising silicon dioxide, silicon nitride, aluminum nitride or the like on the surface of the wafer, and heat-treating the wafer at a specified temperature for a specified time. CONSTITUTION:As ions are implanted in the surface layer of a gallium arsenide single crystal wafer. The composition ratio of GaAs in the ion implanted layer is determined so that As becomes excessive. An insulating film comprising SiO2, SiNx, AlNx or the like is formed. Heat treatment is performed in this state. As As<+> implanting conditions, a dose amount of 1X10<13>cm<-2> and implanting energy of 150keV are used. Then, the effect is acknowledged in the range of several times - several hundred times with respect to the implanted ions of Si<+>, Se<+> and the like. The value of the implanted energy of 30keV is sufficient. Therefore, energy dependence is not so large. The reason is estimated such that the As ions undergo sufficient internal diffusion and the homogeneous As-excessive state is formed under the specified heat treating conditions.

Title: Nozzle plate for ink jet print head
Inventor: SATOU NOBUO
IPC: B41J2/135
Filed: 1981-03-25
Abstract: PURPOSE:To improve the flying-straight property of ink by using a nozzle plate molded of an epoxy resin in which a water-repellet fine particle is dispersed. CONSTITUTION:A nozzle plate molded of an epoxy resin in which a water-repellent carbon fluoride (CF)n is dispersed is provided with 20 fine holes 2 of a diameter of 50mum for example. Thus, for the nozzle plate, no lowering of water repellency occurs, although somewhat abrasion of the surface cold be taken place. For example, in the case of an epoxy resin in which 30wt% carbon fluoride is dispersed, no change in injection direction and also in grain size is observed. Also, as the amount of the carbon fluoride to be added increased, the water repellency of the nozzle plate is increased, but its hardness is reduced. Thus, alumina fine powder is preferably added to the epoxy resin.
