Abstract: PROBLEM TO BE SOLVED: To suppress grinding process to the minimum, and improve work accuracy of a nozzle with a good efficiency by forming a circular cone shaped recessed part facing off against a movable valve from a plurality of surfaces of two or more stages, and differing an angle of a surface having at least a seal function of the movable valve from an angle of a surface faced to an orifice inlet part. SOLUTION: In the case where a fuel injection valve is manufactured, firstly, a seat 1b is pressed in along a cylindrical part 13a of a nozzle raw material 13, and is transferred and molded by a mold punch 14. In this time, a dice 15 is put on a lower surface 13b of the nozzle raw material 13. Then, a plastic fluid protrusion part 13c pushed out to a bottom lower surface of the nozzle raw material 13 is mechanically worked and eliminated. An orifice is worked by a punch 17 serving the seat part 1b as a guide of a punch guide 16. After that, the nozzle raw material 13 is hardened, and the cylindrical part 13a and the seat 1b are simultaneously worked by a grinding wheel having an angle θ' larger than a holding angle θ of the seat 1b. It is thus possible to improve a work accuracy without reducing productivity by plastic work.

IPC: G11B21/02
Filed: 1984-10-25
Abstract: PURPOSE:To attain accurate record/reproduction with high density despite any temperature change by setting the fixing points of a carriage and a drive belt, the record/ reproduction point, the axial core point of a drive shaft and the revolving center point of a magnetic disk at positions where the specific relations are secured among those points and at the same time securing the approximate coincidence of linear expansion coefficient between the magnetic disk and the drive belt. CONSTITUTION:The same size J is set for both the distance between the center H of a magnetic disk 15 and the track position E of the disk 15 and the distance between the drive center I of a driving roller 18 and the driving belt fixing point F of a carriage 12. While a size K is set for attachment of a substrate between the center H and the center I. Thus the alignment accuracy is secured for the disk 15 in its circumferential direction, i.e., the radial direction, and no effect is virtually given to the actual record/reproduction in terms of off-track. For the thermal expansion/contraction of the size J due to the ambient temperatures, a magnetic head has virtually no off- track to the disk 15 that is caused by the environmental change since the approximate coincidence is secured between the thermal linear expansion coefficients of the disk 15 and a drive belt 16.

Filed: 1985-10-08
Abstract: PURPOSE:To obtain a stem for a semiconductor element proper for direct mounting by loading a pressure sensor on a member for loading the element having a specific thermal expansion coefficient. CONSTITUTION:A stem 200 for the semiconductor element consists of metallic leads 21, glass materials 22 for hermetically sealing the leads and an outer ring metal 23 surrounding the glass, and a member 24 for loading the element having approximately the same thermal expansion coefficient as a substrate material for the semiconductor element is arranged into an indentation 23a formed in a semiconductor-element loading region at the central section of the outer ring metal 23. A pressure sensor chip 10 is bonded with the member 24 for loading the element with adhesives 17. Consequently, the chip 10 and the member 24 for loading the element expand and contract only by approximately the same degree to the rise and drop of an ambient temperature, thus hardly generating thermal strain due to a temperature change. Accordingly, a stem for the semiconductor element for directly mounting a diaphragm type pressure sensor sensitive to thermal strain without deteriorating characteristics is acquired.
