Filed: 1985-04-30
Abstract: PURPOSE:To avoid cracking, breakage and element lack of a semiconductor device by a method wherein a substrate and a metal film formed on that substrate are subjected to a heat treatment and an amorphous layer is formed in the substrate region under the metal film and a cut is formed in the surface region of the substrate corresponding to a scribe line. CONSTITUTION:Metal film layers 17 as a guard pattern are formed on a substrate surface along a scribe line 12 and on both sides of the line 12. The substrate 12 and the film layers 17 are subjected to a heat treatment in an inert gas. Metal atoms in the film layers 17 are diffused into the substrate 11 by the heat to form amorphous metal layers 18 in the surface of the substrate 11 near the regions under the film layers 17. An layer insulation film 13 is formed over the whole surface of the wafer by a CVD method. A silicon nitride film 13 is formed over the whole surface of the wafer as a passivation film. A cut 16 is formed in the wafer from the surface of the nitride filn 15 along the line 12. With this constitution, cracking, breakage and element lack of a semiconductor device can be avoided.

Abstract: PURPOSE:To make it possible to perform detection accurately at a required detecting distance without the effects of color, the shape and the like of a body to be detected by arranging a plurality of light emitting elements or photodetectors so that the distance to one photodetector or light emitting element is different. CONSTITUTION:The output signal from an oscillator 3 and its inverted signal (the output of an inverter 4) become the signals for both A and B channels, and light emitting elements 1A and 1B are driven. When the emitted light rays from both light emitting elements 1A and 1B are projected on a body to be detected, the reflected light rays are inputted into a photodetector 2. The received light signals are amplified in an amplifier 7. The signals are divided into the signals for both A and B channels with analog switches 8A and 8B. Both signals are converted into DCs through smoothing circuits 9A and 9B. Thereafter, the signals are inputted into a voltage comparator 11. At this time, the signal SA undergoes level adjustment with a variable resistor 10 and S'A is obtained. When S'A>=SB is obtained, the output of the comparator is inverted, and the detected signal of the body is outputted from an output circuit 12.

IPC: F02M21/02
Filed: 1986-04-23
Abstract: PURPOSE:To prevent gas explosion, by covering an entire gas supply system for a gas fuel using type engine with the use of a sealing pipe, by charging inert gas into the sealing pipe, and by providing a valve for discharging gas leaking into the sealing pipe under the pressure thereof to the atmosphere outside of the sealing pipe. CONSTITUTION:High pressure fuel gas is fed into a gas engine 1 from the outside through a supply pipe 4, and extra gas is returned.

Further, there is provided a safety valve 9 in the outboard end part of the supply pipe 7, for opening the pipe 7 to the atmosphere when the pressure of the pipe 4 exceeds the above- mentioned predetermined pressure. When gas leakage occurs in any part of the system of the supply pipe 4, the pressure in the sealing pipe 7 is raised so that the safety valve 9 opens to discharge the gas to the atmosphere. Since the inert gas is charged in the pipe 7, no firing and explosion do not occur at once.

Title: Dot printer head
Inventor: TAGO MAMORU
IPC: B41J2/275
Filed: 1989-04-13
Abstract: PURPOSE:To absorb the restorative energy of an armature efficiently to stabilize it promptly and shorten a printing cycle to increase printing speed by providing an elastic body which is arranged from the end of the needle side of the armature and protrudes to the rear of the armature farther than an armature stopper. CONSTITUTION:If a specific electromagnetic coil 5 is energized, an armature 8 is attracted by a core 6, rotating at a fulcrum 9, and a needle 13 is caused to run into paper on a platen 2 by the rotation. The needle 13 returns to its home position due to the reactive force of the collision and the restorative force of a needle spring 15. The armature 8 returns to its home position due to the pressure of the returning needle 13 and the restorative force of an armature stopper 19. An elastic body 20 comes in contact with the rear of the armature 8 right before the returning armature 8 comes in contact with the contact surface 19a of an armature stopper 19 and is positioned. At the time of this contact, the restorative force of the armature 8 is reduced by a bending effect. Thus the armature 8 which has returned can be stabilized promptly and the printing cycle can be further shortened accordingly.
