  • Publication number: 20090126434
    Abstract: A press machine in which the service life of a ball thread mechanism is extended. The press machine includes a die 2, a punch 4, a press drive mechanism 6, a height position changing mechanism 21, and a die height position control device 32. The press drive mechanism 6 is configured to move the punch up and down. The press drive mechanism includes at least one ball thread mechanism 10 in which a nut 13 is threaded via balls 12 onto a threaded shaft 11. A rotational drive source 14 is provided to rotate one of the threaded shaft 11 and the nut 13. The position changing mechanism 32 is configured to change the height of the die 2. The die position control device 32 controls the height of the die 2 via the position changing mechanism 21 so that the position varies where the balls 12 come into contact with the inner face of the thread grooves 11a of the threaded shaft 11 during pressing.

  • Patent number: 6341230
    Abstract: A gel layer retained in a retaining member 15, such as non-woven fabric, is placed on one side of an electrode element 1. The electrode element 1 is held by a flexible and extendable tape 11, and the tape 11 adheres to a biological surface tissue. When being plastered onto the biological surface tissue, the tape 11 is covered with cover films 12 and 13, thereby preventing occurrence of a kink in the tape 11. After the tape 11 has been attached to the biological surface tissue, a butt-joined portion between two sub-divisions constituting a cover film 12 is exfoliated to the outside, thus preventing removal of the tape 11.
