As for temperature to be set at a temperature sensor 15, temperatures ranging from the room temperature to temperatures less than a melting point of a film are possible as a temperature immediately before a perforation by the thermal head 3. However, 30 deg.C-70 deg.C is desirable as a temperature where the thermal head is always kept stable at an actual use and about 30 deg.C-50 deg.C is desirable for a film having a high coefficient of shrinkage. A CPU controls the temperature and outputs ON and OFF signals to the heating element 16 and the fan 17 in response to an input signal from the temperature sensor 15.

Title: Grinding method for non-circular work
Inventor: WATABE YOSHIHARU
IPC: B24B19/12
Filed: 1991-11-06
Abstract: PURPOSE:To make a following section following the movement of a grinding wheel light in weight, and thereby enhance the following properties of the grinding wheel as well as to enable grinding to be high in efficiency by grinding an object while the grinding wheel is being rocked around a rocking axis parallel with the axis of the grinding stone. CONSTITUTION:A ball screw 9 is rotated with a rocking motor 12 operated, and a grinding wheel body threadedly engaged with the ball screw is rocked around a rocking axis located down below, so that the relative position with a work is controlled. In this case, the circumferential speed of the grinding stone is changed as the axis 4 of the grinding stone is rocked, the change of the circumferential speed is small as compared with the original circumferential speed, and the aforesaid change is therefore negligible. In this case, moreover, the grinding stone body can be made light in weight because the weight of the wheel body is not integrated with a spindle motor 6. And since the spindle motor 6 is fixed onto the floor surface, the influence of the spindle motor 6 exerting on grinding can be neglected.

Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a conductive stretch tape whose adhesive strength to a member to be shielded is superior without the occurrence of deviation and a gap even if the member to be shielded is deformed by bending. SOLUTION: A conductive stretch tape 2 is composed of a fabric obtained by driving weft 20 having conductivity into a warp 10 constituted of elastic threads which expand/contract in a wiring direction and conductive coating threads 12 that are leno-woven to coat an elastic threads 14. The tape expand/ contract in the direction of warp and it comparatively freely deforms in an oblique direction so that a fold deforms in a lozenge. Thus, it is securely adhered to the material to be shielded in accordance with the surface form at the time of winding it to the member. Since the warp 10 and a weft 20 are leno-woven, the fold is prevented from being enlarged or deviated even if it is pulled from outside. Thus, almost uniform electromagnetic wave shielding effect can be obtained in respective parts.
