Abstract:
A method for manufacturing a wiring board, which prevents electrostatic destruction generated in a mask pattern, by employing a structured exposure mask at a low cost is provided. The method can comprise the steps of forming a photosensitive resin layer on an insulating layer located underneath a predetermined conductor layer, forming a plating resist by exposing and developing the photosensitive resin layer with an exposure light while an exposure mask is disposed on a surface of the photosensitive resin layer, forming a metal plating layer that has a conductor pattern formed by applying a metal plating to an opening of the plating resist, and removing the plating resist. The exposure mask may have a plurality of graphic patterns, and each corner of the graphic patterns maybe chamfered by 50 micrometers or more so that electrostatic destruction due to electric discharge between the adjacent graphic patterns is prevented.
Abstract:
The card connector can adequately detect the state in which an electronic device such as a memory card to be inserted and removed is fitted, and saves the footprint for mounting the card connector. With this card connector, a card detection switch detects a state in which a memory card is fitted in an accommodating part of a housing through an insertion slot. The card detection switch has movable terminals and fixed terminals, and the movable terminals each have a card contact part which is displaced by being pressed by the memory card to be inserted, and a movable contact part which is displaced in a same direction as a direction in which card contact part is displaced following displacement of the card contact part. The fixed terminals are each arranged in the housing to project in a direction to interest the direction in which the movable contact part is displaced, and is slid against by the movable contact part when the movable contact part is displaced.
Abstract:
A graph 261, in which “aperture” is configured on the vertical axis, and “shutter speed” is configured on the horizontal axis, is displayed as superimposed on a through image. On this displayed graph 261, at a position of a parameter value corresponding to a determined photographic scene, an icon 262 of the photographic scene is displayed. When the icon 262 is operated and moved by a user, the display of the icon 262 is changed to a position on the graph 261 where the icon 262 is operated and moved, and values of the vertical axis and the horizontal axis are read off and the corresponding parameter stored in a RAM is updated. When the shutter key is operated, photographic processing is carried out with parameters stored in the RAM, and image data obtained by this photographic processing is recorded in the storage memory.

A sensor device includes: one or more sensor elements each including first and second diode elements connected in series and a sensor driving section. The cathode of the second diode element is connected to the anode of the first diode element. The sensor driving section controls on-off state of the first diode element through changing a gate voltage under a fixed cathode voltage, and controls on-off state of the second diode element through changing a gate voltage under a fixed anode voltage. The sensor driving section drives the second diode element, maintaining a relationship of Vg2(off)
Abstract:
The card connector can adequately detect the state in which an electronic device such as a memory card to be inserted and removed is fitted, and saves the footprint for mounting the card connector. With this card connector (100), a card detection switch (160A) detects a state in which a memory card (20) is fitted in an accommodating part (102) of a housing (110) through an insertion slot (101). The card detection switch (160A) has movable terminals (161) and fixed terminals (162), and the movable terminals (161) each have a card contact part (163a) which is displaced by being pressed by the memory card (20) to be inserted, and a mobile contact part (164a) which is displaced in a same direction as a direction in which card contact part (163a) is displaced following displacement of the card contact part (163a). The fixed terminals (162) are each arranged in the housing (110) to project in a direction to interest the direction in which the mobile contact part (164a) is displaced, and is slid against by the mobile contact part (164a) when the mobile contact part (164a) is displaced.

Abstract:
A connector includes a housing, a plurality of contacts, and a restricting member. The contacts are made of a conductive material. Each of the contacts includes a contacting part and a deformed part. The contacting part protrudes from the housing, is adapted to electrically come in contact with another connector, and is displaced in a first direction when contacts the another connecter. The deformed part is accommodated in the housing and is elastically deformed when the contacting part electrically comes in contact with the another connector. The restricting member is provided in the housing, is contacted to the deformed part, and restricts a displacement of the deformed part in a direction opposite to the first direction.
