Title: Mold for molding disc board and disk board
Inventor: OTA KEIICHI
IPC: G11B7/2405
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To further reduce a molding fault on a disc board by forming a side of an outer peripheral ring opposed to a cavity in an oblique surface structure radially enlarging toward a stamper. SOLUTION: A side 10 of an outer peripheral ring 8 opposed to a cavity is formed in a tapered shape of an oblique surface. Thus, in the state of applying a mold clamping pressure during a cooling step, a force for pressing a board from the side 10 of the ring 8 to a stamper 7 side is generated, release of the board from the stamper surface upon contraction of resin board due to cooling and solidifying during the cooling step is prevented, and hence double transfer of a pit or mold releasing irregularity is prevented. An oblique surface formed on the side 10 of the ring 8 is about 1 deg. or more, desirably about 3 or more or further desirably about 4 to less than 90 deg..

Title: Production of honey-comb diaphragm
Inventor: IWASA MIKIROU
IPC: H04R7/10
Filed: 1980-01-19
Abstract: PURPOSE:To obtain honey-comb diaphragm with flat surface by arranging the surface material to which thermoplastic adhesive is applied on the surface of a honey-comb core, setting a metallic plate on the other surface of the surface material and pressing the other surface of the metallic plate with a heating plate. CONSTITUTION:Honey-comb core 1 consisting of aluminum foil is set on base board 3 and surface material 2 consisting of aluminum foil to which thermoplastic adhesive has been previously applied is set on the upper surface of core 1. Aluminum plate 4 finished with a fine flatness by preheating is mounted on the upper surface of surface material 2. When heating plate 5 is pressed against the upper surface of aluminum plate 4 in order to perform heat-press, thermoplastic adhesive applied to surface material 2 is melted and surface material 2 is adhered to the surface of core 1. Since aluminum plate 4 is sandwiched between heating plate 5 and surface material 2, surface plate 2 is not heated suddenly and, in addition, both surface material 2 and aluminum plate 4 are expanded or contracted uniformly because their materials are the same, increasing the flatness of surface material 2. Thus, the lowering of the bending rigidity of diaphragm and the drop of regenerative high threshold frequency can be prevented.

Filed: 1989-01-11
Abstract: PURPOSE:To raise and lower a table in parallel by constituting the title device so that oil is continuously supplied into a ram cylinder by opening an oil pressure selector valve when the piston of a differential cylinder reaches the max. projection cycle. CONSTITUTION:Though the oil on the upper part division is supplied into a ram cylinder B side, accompanied with the discharge cycle of the piston 3 of a differential cylinder A, a ram 6 projects in synchronization with the cycle of the piston 3, since the sectional area of the ram 6 and the sectional area of the upper part division of the differential cylinder A are equal. Further, when the ram 6 is in lowering, the oil in the ram cylinder B is discharged into the upper part division of the differential cylinder A, and the ram 6 and the piston 3 lower in synchronization. Therefore, a table 1 can be lowered in parallel.
