摘要:
A contact includes a plate with a width that ranges from 0.1 mm or more to 1 mm or less, and a stress concentrated place, where a surface roughness (Ra) on the stress concentrated place is 0.2 μm or less. When samples whose surface roughness Ra is 0.040 μm, 0.080 μm, 0.120 μm, and 0.180 μm were used to study a number of repetitive fracture times, as the surface roughness Ra was smaller, the number of repetitive fracture times became larger. Particularly, it is found that the surface roughness Ra may be 0.200 μm or less in order to satisfy 3000 times as a number of operating times of the battery connector. Further, the surface roughness Ra may be 0.080 μm or less in order to satisfy 6000 times as the number of operating times when a safety factor is 2.

摘要:
A mold is fabricated with a cavity formed in an insulating layer formed so as to be placed on an upper surface of a conductive base material. This mold is disposed in an electrolyte bath to be applied with a voltage, and a metal is electrodeposited on the bottom surface of the cavity to electroform a metal-formed product in the cavity. In this electrodepositing process, when the width of the cavity is taken as W and a vertical height of a head space between an upper opening of the cavity and an upper surface of a metal layer is taken as H, the growth of the metal layer is stopped so that the height H of the head space left above the metal layer satisfies: H≧W/2.85 where 300 μm≦W; H≧W/3.75 where 200 μm≦W

摘要:
The present invention provides an electrocasting method by which the shape of the surface opposite to the surface to be electrodeposited on the mold can be controlled. A molded metal article is electrocast by forming an insulating layer on the side wall faces of a cavity and the outer wall face of a conductive mold in which the cavity is formed, placing the mold in an electrolysis tank and applying voltage, electrodepositing metal on the bottom face of the cavity, and growing the metal layer in the cavity so as to leave a space having a height of at least one-third the width of the cavity.

The device includes a transfer section that conveys a transfer film while conveying the printed sheets and repeatedly transfers patterns of the transfer film onto the printed sheets. A tension adjusting part that adjusts tension on the transfer film is provided to transfer the patterns of the transfer film at the predetermined positions on the printed sheets.
摘要:
There is provided a method of winding up a transfer film and a device for performing transfer printing on printed sheets of paper, capable of eliminating the need to frequently replace the transfer film, thereby allowing the transfer film to be used over a prolonged time. According to the method of winding up a transfer film, the transfer film fed from a feed roll through a feed path is pressed onto a fed printed sheet to transfer patterns of the transfer film, and then the transfer film is wound up onto a windup roll through a windup path. During the rewind of the transfer film from the windup roll to the feed roll, a lateral position of the transfer film running along the feed path is detected, and the feed roll is moved in its axial direction to follow a lateral positional change of the transfer film.
