Title: Soundproofing cover for electromagnetic type injection valve
Inventor: SHIRABE NAOTAKA
IPC: F02M69/04
Filed: 1986-02-20
Abstract: PURPOSE:To reduce the generation of working noise of an injection valve, by a method wherein a soundproofing cover made of rubber, on the inner wall of which projections are formed, is attached in a state to wholly cover the outer periphery of an electromagnetic type injection valve therewith. CONSTITUTION:A soundproofing cover 7, the tip of which is inserted in a recessed part 29 formed in an intake air pipe 2, is attached in a state to wholly cover the outer periphery of an injection valve 1 therewith. Wedge-shaped projections 7a are formed on the inner wall of the soundproofing cover 7. Since, by applying a periodical electric signal on the injection valve 1, the injection valve 1 is repeatedly opened and closed, and mechanical impact between metals is produced at the stopper part and the valve seat part of a valve body, metallic hammering noise having relative high frequency is generated. The noise is transmitted to the outer periphery of the injection valve 1 and radiated to the surroundings, but the noise is collided with and reflected by the projection 7a formed on the inner wall of the soundproofing cover 7 made of rubber, and is collided with and reflected by the adjoining projection 7a again to repeat the aboves. During repetition of the aboves, working noise is transmitted to a position in the vicinity of the root of the projection 7a, and a fair amount of the noise is absorbed by rubber for damping.

Abstract: PURPOSE: To improve reliability by supplying a voltage regulator between a power supply and glow plugs.  
     CONSTITUTION: A voltage-regulating resistance 25 is put between a power supply 1 and glow plugs 26 to 29. When a movable contact point 3 of an engine starting switch 2 is connected to a contact point 5, a timer circuit 8 activates to energize the coil 21 of a relay 20. The usual-open contact point 22 is closed to feed the glow plugs 26 to 29 with current directly for a specified period. Next when the movable contact point 3 is connected to a fixed contact point 7, current is fed to a coil 23 through contact points 3, 7, and the contact points 16, 18 of a self-holding relay 10. And the contact point 24 is closed to charge the glow plugs 26 to 29 with current through a resistance 25. A heating coil, prevented from fusing by a resistance 25, conducts cracking.

Title: Manufacture of gallium phosphide
Inventor: HISATOMI KIYOSHI
IPC: C01B25/08
Filed: 1979-03-29
Abstract: PURPOSE: To provide GaP in a high yield and with little degree of dissociation of formed GaP into Ga and P, by heating GaPO 3  under a reducing atmosphere and a specific temperature.  
     CONSTITUTION: GaPO 3  is heated at 200W900°C under a reducing atmosphere to effect high-yield GaP production according to the reaction of GaPO 3 +3H 2 → GaP+3H 2 O. This production method, characterized by reduction of unstable GaPO 3 , allows the reaction to proceed well at a low reducing temperature. For example, this reaction occurs at 600°C, while GaPO 4  needs 900°C for the reaction to proceed. Because of the low reducing temperature, the dissociation reaction by which the formed GaP dissociates into Ga and P little occurs, and so a high yield is obtained.

Filed: 1981-03-16
Abstract: PURPOSE:To remove a sag generated in a synchronizing signal by applying a signal consisting of only distorsion components obtained by a sample holding circuit to a video signal through a subtraction circuit. CONSTITUTION:An energy diffusion signal is removed from a video signal superposing the energy diffusion signal by a clamping circuit 8 after being passed through an input terminal 7. At that time, the output of the circuit 8 has a  waveform with a sag in a vertical synchronizing period. The output of the circuit 8 is held by a sample holding circuit 10 until the next sampling signal  when horizontal and vertical cynchronizing signals separated by a synchronizing separation circuit 11 are regarded as a sampling signal. As a result, a voltage  waveform generated on the output terminal of the circuit 10 corresponds to the  synchronizing signal. The signal fetched in such a manner is applied to a subtraction circuit 9 and said signal and the video signal supplied from the circuit  8 are synthesized, generating a signal from which distortion generated during  the vertical synchronizing period and the sag are removed.
