Patent number: 7871152Abstract: A discharge head includes a discharge driving element; an individual electrode formed on the discharge driving element and having a connecting section; and a wired board having a terminal which is joined to the individual electrode by a conductive brazing material. The connecting section is provided to face the terminal, and a metal, which is hardly sulfurized, is exposed in a facing area, of a surface of the connecting section, facing the terminal. A silver sulfide coating is formed on a surface of the connecting section except for a portion facing the terminal. The silver sulfide coating has a low affinity for the conductive brazing material, which is hardly wetted thereby. Therefore, even when the conductive brazing material leaks, then the conductive brazing material is not retained on the silver sulfide coating, and no influence is exerted on the driving operation of the discharge head.Type: GrantFiled: June 27, 2008Date of Patent: January 18, 2011Assignee: Brother Kogyo Kabushiki KaishaInventors: Shigeru Suzuki, Shuhei Hiwada

Patent number: 7864531Abstract: An electronic device includes an FPC, a circuit chip arranged on the flexible flat cable, a heat sink arranged on the circuit chip to release a heat of the circuit chip, and an elastic member arranged on a lower surface of the FPC. The upper surface of the FPC is large enough to cover a contact surface of the circuit chip. The elastic member does not overlap with an apex portion of the circuit chip, but overlaps with the circuit chip at an inner side of the apex portion. Therefore the elastic member does not press the FPC against the apex portion of the circuit chip. Accordingly, the FPC at a position corresponding to an apex of the circuit chip is suppressed from being distorted, and there is no fear of breaking of wire and exfoliation of the circuit chip.Type: GrantFiled: April 8, 2008Date of Patent: January 4, 2011Assignee: Brother Kogyo Kabushiki KaishaInventors: Yasuhiro Kato, Shigeru Suzuki, Koji Imai

Patent number: 7730669Abstract: Elongate bases (10) for guiding a movable end (37) of a conductor path (30). Cross sections taken through the bases substantially normal to the elongation directions of the bases are substantially identical to one another and substantially constant along the elongation direction of the bases. Thus, the bases (10) can be obtained by cutting an elongated raw material to a specified length in conformity with a vehicle type, thereby enabling a cost reduction. Further, since the bases (10) are symmetrical with a moving path of the movable end (37) located therebetween, it is sufficient to prepare only one kind of elongated raw material. In this respect as well, costs can be reduced.Type: GrantFiled: September 16, 2004Date of Patent: June 8, 2010Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Yuji Kida, Shigeru Suzuki, Yoshinao Kobayashi
