Abstract: PURPOSE:To simplify shape and improve the workability of an fuel injection valve by forming a fuel passage in such a way as forcing a circular armature to abut partially on a polygonal armature guide, and forming a fuel passage in such a way as forcing a circular valve member to abut partially on a polygo nal valve guide. CONSTITUTION:A circular armature 36 is slidably stored in an armature guide 6 while abutting partially on the square inner diameter part of the armature guide 6, and four passages 24a to 24d are formed between them. The square inner diameter part on which the valve member 20 of the armature 36 is welded, is welded to the circular valve member 20 while abutting partially on four points, and four passages 25a to 25d are formed between the armature 36 and the valve member 20. The circular valve member 20 abuts partially on four points on the square inner diameter part of a valve guide 7, and four passages 26a to 26d coupled to an accumulation part 15 are formed between them. It is thus possible to eliminate necessity for forming a plurality of passage holes on the valve guide 7 and the armature 36 by drill working.

IPC: F02M31/20
Filed: 1999-11-09
Abstract: PROBLEM TO BE SOLVED: To provide a fuel tank system to radiate the heat without heat insulation when the temperature in a fuel tank rises. SOLUTION: A fuel tank body 10 is of a two-layer tank structure comprising an inner tank shell 26 and an outer tank shell 28, and a space 30 is formed therebetween.

Abstract: PROBLEM TO BE SOLVED: To line up and individually carry vacuum packaged bodies by returning a line independent carrying part to the original position so as to carry the following packaged body intermittently supplied by a carrying-in conveyor onto the line independent carrying part. SOLUTION: When a vacuum packaged body PS is transferred from an intermittently driven carrying-in conveyor 1 to the line independent carrying part 3 of an individual feeder 2 situated opposite to the terminal part thereof, all line independent carrying conveyors 4, 5, 6 constituting the line independent carrying part 3 are also driven.

Inventor: SHIBAZAKI JUNICHI
IPC: H01S3/097
Filed: 1990-11-22
Abstract: PURPOSE:To enable a pulse laser oscillation device to be lessened in inductance and stabilized in discharge characteristics by a method wherein a compression spring is interposed between the ends of a flexible conductor through the intermediary of insulators, and the flexible conductor is made to bear against the terminals of both casings. CONSTITUTION:A travel delta of a flexible conductor 11 is determined by the vertical downward pressing force induced by the gravity of a power supply casing 2 and the vertical upward expanding force of a compression spring 13. The conductor 11 and the terminals 5a and 5b of a compression circuit and the terminals 6a and 6b of a discharge section are brought into area contact enough with each other, so that a current is prevented from being shut off. By this setup, even if the space between the casings 2 and 3 and between the casings and the lead-out terminals are set narrow, an assembly operation is smoothly carried out, so that an electrical circuit which connects a pulse power supply with a laser discharge section can be formed compact, consequently a pulse laser oscillation of this design can be lessened in inductance and stabilized in discharge characteristics.
