Title: Production unit for plastic hollow body with movable mandrel
Inventor: GERUHARUTO RINSU
IPC: B29C49/02
Filed: 1988-02-12
Abstract: An apparatus is disclosed that is intended for manufacturing a hollow body. The hollow body has a head piece formed by blow-molding a preform segment. The apparatus includes a ring-shaped nozzle, a withdrawal device, and blow-mold pieces which are laterally, reciprocally movable. Regions of the hollow body are fabricated to have outer diameters which are less than the diameter of the extruded tubular segment before the segment is blow-molded. This is achieved by a reciprocally movable mandrel with a molding extension. The molding extension extends both radially and inwardly between projecting regions of the closed blow-mold pieces. The projecting regions of the blow-mold pieces press the corresponding parts of the preform segment against the molding extension, wherewith the ring-shaped nozzle opening is radially, outwardly offset with respect to the outer contour of the molding extension. Following the extrusion, the molding extension is advanced downward, in the embodiment illustrated, and serves as an implement for forming the inner shape of the reduced-diameter region or regions of the body part, and as an opposing thrust element for the blow-mold pieces which press together a region or regions of the tubular preform segment.

Filed: 1995-02-17
Abstract: PURPOSE: To improve the operation of a magnetic disk device by quickly removing dust floating right after a spindle revolution at the initial stage and preventing detached dust from an HDA mechanism from being generated after the spindle revolution is returned to the normal speed of revolution. CONSTITUTION: A spindle 7 interposing a disk 4 performs a spindle revolution sequence operation 1 by the command from a spindle control part 10. In the operation 1, the stationary speed of revolution control of two steps is performed in such a manner that the revolution of the spindle is started up from a spindle stoppage at a spindle start 1a and right after the revolution, the spindle 7 is maintained in a revolution state 1b faster than a normal speed of revolution 1d performing an R/W operation for a fixed time and thereafter, the spindle 7 is made to become the normal speed of revolution at the time of the R/W operation by switching a revolution control at 1c.  Then, dust floating right after the spindle revolution is quickly removed in the initial stage and moreover the detached dust after the revolution of the spindle is returned to the normal speed of revolution is prevented from being generated. Thus, the reliability of the operation of the magnetic disk device is improved.

Filed: 1984-02-17
Abstract: PURPOSE:To enable to realize the target semiconductor device without passing through a process, wherein a P type diffusion layer formed on the side of eigher of both main surfaces of the semiconductor substrate is removed, by a method wherein N type impurities of high concentration are diffused from the surface of the P type diffusion layer formed on the side of the main surface of the semiconductor substrate and the P type diffusion layer is made to invert into an N type diffusion layer. CONSTITUTION:P type impurities, such as Ga impurities, are thinly diffused from the side of both main surfaces of an N type semiconductor substrate 11 for forming a P type layer 12a and a P type layer 12b. At this time, an SiO2 film 13, with which the whole of the semiconductor substrate 11 is covered, is simultaneously formed by performing a heat oxidation. After the SiO2 film 13 on the side of one main surface of the semiconductor substrate 11, such as the SiO2 film 13 on the side of the P type layer 12a, was removed, N type impurities, such as P impurities of high concentration, are diffused from both main surfaces of the semiconductor substrate 11. In this case, when the P impurities are diffused for a prescribed time, the P type layer 12a is made to invert into an N<+> type layer due to the difference between the diffusion rates in both main surfaces of the semiconductor substrate 11, because the concentration of the P impurities is high. Then, a drive-in heating process is performed, and after that, an N<+> type layer 14' of the target diffusion depth which penetrates the P type layer 12a is obtained. After this, various treatments are performed and the target diode pellet is obtained.

Abstract: PURPOSE: To prevent the brittle fracture which is likely to occur in bonded parts (bonded parts between deposited metal and base metals) by intermittently changing welding voltage and providing protursions of a fixed interval in weld beads.  
     CONSTITUTION: In the arc welding method of applying voltage between a weld pool 3 and electrode wire 6 and performing welding while forming weld beads 2 between the butted base metals 1, 1, the above-mentioned applied voltage is intermittently increased to increase the penetration of the base metals 1 and form protrusion 2a at a fixed interval in the weld beads 2 (here 7 is a water cooling copper plate). If the protrusions 2a such as the above are formed, the direction of residual welding stress becomes in the arrow 8 direction and the progressing direction of brittle fracture becomes in the direction (arrow 9) orthogonal to this, due to which the brittle fissure 10 having advanced straightforward in the bonded parts deviated to the base metal 1 side, hence the advance of the fissure 10 stops and the brittle fracture is prevented.
