Patent JP-S57100663-A (JP)
Title: Manufacture of guide roller for magnetic tape cartridge
Inventor: YAMAMOTO OSAMU
IPC: B29C45/26
Filed: 1980-12-15
Abstract: PURPOSE:To obtain high-precision products by setting the size of the internal circumferential surface of a loose piece so that the external diameter of a guide roller at a top circumference position on the external cylindrical surface of a cylinder part in the force is a little bit greater than that of the lower part. CONSTITUTION:Forces of basically the same structure with conventional one are used. The forces are combined and when a plastic material is injected and set, the bottom force is separated downward on the whole from the loose piece 11 and top force 12. In this case, the lower part of a cylinder part 7 has an undercut surface 15, so a formed guide roller 4 while supported by the bottom force 13 is released forcibly from the loose piece 11 and top force 12. In this process of forcible releasing, an upper collar part 5 deforms inward elastically and a part of the deformation resides unavoidably, but setting the formation internal surface of the uppe part of the release force 11 to a large diameter D'' a little bit greater than a regular size D suppresses the external diameter difference between the upper and lower parts of the running surface of the guide roller 4 low.

Title: Power operable chuck
Inventor: KEMPKEN RAINER
IPC: B23B31/175
Filed: 1986-07-30
Abstract: A power-operated chuck that is provided with a plurality of clamping jaws that are disposed in a chuck body in such a way as to be radially movable. The radial clamping movement of the clamping jaws is produced by a gear mechanism disposed in the chuck body and via an axial movement of a drive member. Radial positioning of the clamping jaws relative to the starting position of the drive member is adjustable, prior to carrying out a clamping stroke, for shifting the clamping stroke within the clamping range, with adjustment being effected by an adjustment member that acts simultaneously upon all of the clamping jaws. Via an additional axial movement, the drive member can be conveyed to a position that is beyond the clamping range, and in which position the clamping jaws are uncoupled from the drive member. An additional adjustment member is axially movably disposed in the chuck body. This member is connected via respective gear mechanisms to all of the clamping jaws, and during clamping movements of the drive member is carried along in a non-powered state. When the clamping jaws are uncoupled from the drive member, the adjustment member can be operated in a controlled manner to carry out a radial adjustment of the clamping jaws relative to the drive member.
