  • Patent number: 10187976
    Abstract: A flexible printed circuit board (FPCB) is disclosed. The FPCB can be employed to connect an interface card having connectors with a two-stage configuration to a connection destination of a portable information equipment. The FPCB includes a bend line located between an upper-stage terminal group and a lower-stage terminal group. The FPCB can be bent along the bend line to allow the upper-stage terminal group and the lower-stage terminal group to be mutually superimposed over each other. In addition, the upper-stage terminal group of the FPCB is connected to the upper-stage-side connector terminal group of the interface card, and the lower-stage terminal group of the FPCB is connected to the lower-stage-side connector terminal group of the interface card.

  • Publication number: 20180190839
    Abstract: A photoelectric conversion element includes a composite passivation film disposed on a second surface of a semiconductor substrate that is opposite to a first surface on which light is incident. The composite passivation film includes a first passivation film having negative fixed charges and a protection film that protects the first passivation film. This allows the carrier collection efficiency of the photoelectric conversion element to be improved.

  • Patent number: 8377870
    Abstract: The antimicrobial aqueous solution of the present invention comprises an original undiluted aqueous solution containing: 25 ?g/ml to 50 ?g/ml of an amphipathic preservative comprising a monoglycerol monolaurate; and 12.5 ?g/ml to 30 ?g/ml of an ?-polylysine. In preparing the antimicrobial aqueous solution, dissolution of the amphipathic antimicrobial can be promoted by addition of a sucrose monolaurate and by heating to 35° C. to 60° C. This antimicrobial aqueous solution can be used effectively, even within a range of concentrations lower than concentrations to be typically used for amphipathic antimicrobials. It is possible to adopt a diglycerol monolaurate, instead of the monoglycerol monolaurate.

  • Patent number: 6254410
    Abstract: Described is a connector in which a plug can be pulled out of a receptacle without producing stress in the connector itself or a circuit board on which the connector is mounted. The plug is inserted into the receptacle so that the side wall of the plug makes contact with the interior wall of the receptacle. When the plug and the receptacle are coupled, a fitting space is formed therebetween. When compressed air is injected into this fitting space, the plug will be pushed up by a rise in the air pressure and therefore the plug can be pulled out of the receptacle. The use of air pressure in the fitting space to pull out the plug is advantageous because it can be implemented without producing biased stress in the plug or the receptacle.

  • Patent number: 5997083
    Abstract: A vehicle seat, the seat cushion of which is divided into front and rear cushions in a fore-and-aft direction. The front cushion is rotatably mounted at its front-side lower end on a front end of a cushion frame of the vehicle seat to be tilted forward or backward. The rear cushion is placed behind the front cushion and supported by a lift mechanism mounted on a rear portion of the cushion frame. The lift mechanism is interlocked with the front cushion to raise the rear cushion to an upper position when the front cushion is tilted forward and to lower the rear cushion and place it behind the front cushion on the cushion frame in a horizontal condition when the front cushion is tilted backward and placed on the cushion frame.
