Title: Connector device for cards
Inventor: AKIRA NISHIOKA
IPC: H01R13/53
Filed: 2002-11-19
Abstract: The present invention relates to a connector device for cards, which can prevent the circuit and the like in the card from damage when the connector device for cards with a metal case is inserted with a card having static charge. To solve the problem, the case 22 is arranged with first, second and third static prevention means 30, 40, 50. The first static charge prevention means 30 is formed by arranging protrusions 31 on the upper part of the case 22. The second static charge prevention means 40 is formed by arranging a pair of protrusions 41 on the left and right terminals of the front part of the case 22. The third static charge prevention means 50 is formed by arranging a cut 51 on the front edge of the case 22. Accordingly, the static charge carried by the card 10 is released from the grounding contact parts 12a to the case 22 instead of from the signal contact part 12c, thereby preventing the IC and memory data in the card 10 from damage.

Title: Thin film covering toner
Inventor: ETOU KEI
IPC: G03G9/087
Filed: 2003-08-22
Abstract: The present invention provides a thin film covering toner. Because a thermosetting resin covers the surface of the low melting point powder toner, the softening temperature of the powder toner is not increased and therefore the toner with sufficient blocking resistance can be achieved. It results in the possibility of low temperature fixation and becomes more significant while using urea resins as the thermosetting resin and polymer toners as the powder toner. By using such surface covered powder toner with low softening temperature and low blocking property to achieve low temperature fixation, it is possible to accomplish a decrease of required thermal energy during fixation, a shortening in fixation time, energy saving in fixation process, and a high fixation processing speed.
