Title: Portable wireless equipment case
Inventor: HAYASHI TAKAHIRO
IPC: H04B1/38
Filed: 1988-08-19
Abstract: PURPOSE:To achieve insertion into a sheet-like object for portability without causing plastic deformation of a spring by supporting a clip from the inside of a case elastically with a spring and restricting rotation of the clip by a stopper. CONSTITUTION:Normal, with a clip 12, a securing nib 12b is subject to pressure contact to the surface of a case 11 by elastic force of a spring board part 13a of a spring 13. When a sheet-like object is inserted between the securing nib 12b and the surface of te case 11, the clip 12 spreads the gap with the surface of the case 11 while being supported elastically by the spring board part 13a and holds the inserted object. In this case, if the clip 12 is spread excessively, a stopper part 13b of the spring 13 hits against a stopper receiving part 11c, thus restricting the rotation of the clip 12. It achieves insertion into the sheet-like object securely without causing plastic deformation for portability.

Title: Grinding method for tapered surface
Inventor: IMAI HIROYUKI
IPC: B24B5/14
Filed: 1989-08-14
Abstract: PURPOSE:To grind a tapered surface efficiently by mounting a work on a table at whose surface a friction support body is fixed, and sending a grindstone in the cutting-in direction of a work under a condition in which the rotation axis of the grindstone is made to agree with the rotation axis of the table, as the table and the grindstone that is formed into a conical shape are being rotated together. CONSTITUTION:A work 3 makes a slide movement on a friction support body 2a in the direction of a portion which butts into a grindstone 1, and in addition, the grindstone makes a movement, and when a condition in which its conical grinding surface 1a comes into contact with the whole perimeter of the work tapered surface 3a, is realized, the center line of the work and the rotation axis 1c of the grindstone agree, and the center adjustment of the work is automatically made, as the rotation axis 1c of the grindstone and the rotation axis 2c of the table are already made to agree. When this condition is brought in, the work comes into a condition in which it is pressed against the friction support body of the table, due to a table rotation axis direction grinding resistance component force, and a large friction is generated between the work and the friction support body. Accordingly, the work 3 rotates together with the table 2, and its tapered surface 3a is processed in grinding.
