Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To prevent the transfer defect, such as transfer drop-out, by formation of toner images further in the parts where waving, etc., are generated by the formation of the toner images with an image forming device which forms the toner images twice on the same surface of a transfer material.

Title: Contact for connector
Inventor: OZAWA HIROAKI
IPC: H05K1/11
Filed: 1989-12-22
Abstract: PURPOSE:To reduce stress concentration in a bending portion, and disperse a contact pressure acting on a contact end so as to enhance contact reliability by squeezedly bending the bending portion under pressure, and forming the contact end into a curve. CONSTITUTION:A contact for a connector comprises a terminal base 2 secured to the connector, a contact end 3 in contact with a connection terminal of such as an electronic equipment, a boundary between the terminal base 2 and the contact end 3, i.e., a bending portion 4, and a fixing portion 5 for preventing the contact from being drawn out from the connector. The bending portion 4 is bent and squeezedly, and the contact end 3 is formed into an S-shaped curve. Consequently, a stress generated by a contact pressure can dispersingly act over the whole contact end formed into a curve without concentrating in the bending portion. Therefore, contact fatigue can be reduced, and further, reliability can be enhanced.

Title: Rhythm code generating device
Inventor: KOJIMA YUICHI
IPC: G10L13/08
Filed: 1991-11-20
Abstract: PURPOSE:To always correctly read out sentences by generating a rhythm code according with the intention of an operator even in the case of the sentence including unregistered words.
