Title: Guide mechanism in expansion structure
Inventor: MORINO MIKI
IPC: B64G1/22
Filed: 1992-11-17
Abstract: PURPOSE:To stably expand a truss body by installing guide rollers on the cube of the truss body and by providing a supporting plate with a guide for guiding the guide rollers to restrain the movement of the cube until at the final stage of expansion. CONSTITUTION:An expansion structure has a cube 3 comprising a long and narrow material for forming a truss body by expansion in the unidimensional direction. In expanding the expansion structure, for example, traveling rails 11 upwardly folded are forwardly turned and expanded at the front of a housing 5. The cube 3 at its frontmost part is pulled along the traveling rails 11 trough traveling rollers 10. Guide rollers 15 installed on tire back part of the long and narrow material are guided along an upper side guide plate 17a interposed on a supporting plate 16 for the traveling rails 11. Thus, the front movement of the traveling rollers 15 is restrained until at the final stage of the expansion of the cube 13. The rest part of the cube 3 is, therefore, prevented from being pulled out of the housing 5 for flowing.

Filed: 1992-12-11
Abstract: PURPOSE:To accelerate a pull-in phase of a capstan start motor by deciding a start timing with a pulse counted value of a signal for detecting a rotating speed of the motor from a start/stop of the motor. CONSTITUTION:When information for switching a normal reproduction to a still command is inputted from a terminal 916 to a microcomputer 917, a capstan motor 925 is stopped at a rising edge timing of an RFS signal 102.

Title: Method for removing resist
Inventor: YAMAMOTO MASAYUKI
IPC: B29C63/00
Filed: 1997-12-02
Abstract: PROBLEM TO BE SOLVED: To easily and surely remove a resist pattern together with an adhesive tape, by removing the resist pattern by stripping off the adhesive tape from an object with the adhesive tape after the object is quickly cooled. SOLUTION: An adhesive tape T on which a semiconductor wafer W is stuck is shifted onto a stripping table 6 and the wafer W is quickly cooled from its upper and lower surface while the wafer W is held between the table 6 and a cooling board 7. When the wafer W is cooled in the above-mentioned way, a resist pattern on the wafer W quickly shrinks and cracks occur, resulting in the deterioration of the adhesion between the pattern and the wafer W. When this quick cooling step ends, the cooling board 7 is retreated upward and the adhesive tape T is stripped from the surface of the wafer W by moving a stripping roller 10 forward. As the tape T is stripped from the surface of the wafer W, the resist pattern on the wafer W is stripped and remove from the wafer W together with the tape T.
