Title: Guide shaft for movable body
Inventor: NAKAYAMA SHO
IPC: B21H3/02
Filed: 1984-12-17
Abstract: PURPOSE:To markedly reduce machining time, by providing a movable body guide shaft with a guide groove by only thread rolling, in a printing head guide mechanism for a small-type printer. CONSTITUTION:In a thread rolling process for forming a groove 3a, the shape of a die is so set as to generate such a material flow that slant side wall surfaces 3b, 3c and upper surfaces of protuberant parts 3d can be continuous with each other through R curved surfaces 3g, thereby restricting the flow of the material forming the protuberant parts. When the blank material is ground to an outside diameter D1 by outside diameter grinding, a part of the R curved surface 3g is located below an upper edge surface of the groove 3a constituted of the outside diameter D1 and on the outside of an upward extension line 3f of the slant side wall surface 3b, 3c. When the blank material is subjected to outside diameter grinding by centerless grinding, the groove is so shaped that burr 3e formed on grinding to protrude beyond the upper edge surface of the groove 3a is located on the outside of the extension line 3f of the side wall surface 3b, 3c, so that even if groove grinding for removing the burr 3e is not conducted, the groove 3a can be sufficiently smoothly engaged to a projection 2b of a printing head 2.

Filed: 1996-09-14
Abstract: PROBLEM TO BE SOLVED: To reduce the wind noise level by spirally forming steps lower than the outer periphery of a step section protruded strand in the longitudinal direction on the outer periphery of an electric cable. SOLUTION: Step low face forming strands 5, 6 forming step low faces 7, 8 lower by the height (h) are arranged and twisted on both sides of a step section protruded strand 3 on the outermost layer surface of an electric cable, and steps are spirally formed in the longitudinal direction on the outer periphery of the electric cable. When the wind noise level is measured on the electric cable thus obtained, it is found that the wind noise level of the prevailing frequency can be reduced by 10db or above if D1 =D2 =38.4mm, H=4.8mm, the step (h) is about 0.35-1.5mm, i.e., a sufficient wind noise reducing effect can be expected if 0.35<=h<=1.5mm, where D1 is the diameter of the circular envelope inscribed with the outer periphery 9 of the protruded strand 3, D2 is the diameter of the outermost layer periphery of the electric cable (D1 =D2 in the configuration of this electric cable), and H is the thickness in the radial direction of the protruded strand 3.

Abstract: PURPOSE:To prevent the break of a conductor at a head connection terminal by running the external conductor through a heat-shrinkable tube and then inserting it into the through hole of a turntable after heating part of the conductor, and fixing the conductor to the turntable at the border of a shrinkage and a nonshrinkage part. CONSTITUTION:The external conductor 6 which connects the connection terminal of the magnetic head 1 to an external circuit is run through the heat-shrinkable tube 7 and part of it is heated to form the nonshrinkage part 7a and shrinkage part 7b, thereby holding the conductor 6 at the shrinkage part 7b. The conductor in this state is inserted into the through hole 5c of the turntable 5 and then caught at the entrance because the diameter of the nonshrinkage part 7a is larger than the diameter of the through hole, but the tube 7 is further drawn out as shown by an arrow D to press the boundary part in the through hole 5c elastically, thereby fixing the conductor 6 to the turntable 5. Consequently, even when the head 1 rotates according to a tape traveling direction, the part above the fixation part rotates in one body to prevent the break of wiring at the terminal part 4.

Title: Clutch operating device
Inventor: TAKAIWA KIYOYUKI
IPC: F16D25/08
Filed: 1987-10-21
Abstract: PURPOSE:To rapidly and smoothly engage and disengage a clutch by controlling a supply or discharge valve so as to alternately change over the same between open and close conditions, and by setting the first opening period of the valve to be longer than the second opening period thereof. CONSTITUTION:Since the friction coefficient of a clutch is relatively high if a push rod 13, a relay piston 11 and a piston 6 are set under a stationary condition, a comparative time should be required for the initiation of in-coming movement of the piston 6 if energization by a short-time would be performed every constant period, resulting in a large delay between the time point of initiation of turn-on and -off control of a solenoid valve 21 and the time point of initiation of in-coming movement of the piston 6. However, since the first energizing period of the solenoid valve 21 is set to be longer during turn-on and -off control, compressed air in a working chamber 7 in a cylinder 5 is abruptly discharged into the outside during this first energizing period so that the in-coming movement of the piston 6 is initiated in a short time. Accordingly, it is possible to improve the responsiveness during semi-clutch operation.

The cover 3 is adjusted so that the optical axis of the lens 3 agrees with the optical axis of the semiconductor laser 2. Thereafter, the cover 3 is rigidly fixed to the case 1 by laser welding. After the case 1 and the cover 3 are fixed, the entire package comprising the case 1 and the cover 3 is heated, and the solder embedded in the groove 12 of the case 1 is fused. Then the fused solder intrudes into the gap between the case 1 and the cover 3 by a capillary phenomenon. Thus the cavity part in the case 1 can be sealed.
