The single-use camera has a main body in which is housed the film cartridge and around which a cover member is formed. On the main body of the camera is a closure and a spring which are used to close the light-shield cover in the film gate of the cartridge when the cover is opened to remove the film cartridge.
摘要:
A single-use camera which is loaded with a film cartridge having a light-shielding cover on a film gate thereof. The single-use camera includes: a cover for covering the film cartridge when the cover is at its closed position, a closing member for closing the light-shielding cover of the film cartridge, a stopper for keeping the cover member at the closed position, and a stopper release for releasing the stopper so as to allow the cover to be open while the light-shielding cover is being closed by the closing member.

A manufacturing method forms flanges for use in a film cartridge which are made of resin. Each flange is made of the resin by an injection molding process. Gates to cavities provided in a mold are located such that residual portions of solidified resin at the gates, remaining after the injection molding process has been completed, do not come into contact with a film in the cartridge as the film is moved into and out of the cartridge.

A coil component includes: an insulating resin layer provided between a first planar spiral conductor formed on a back surface of a first substrate and a second planer spiral conductor formed on a back surface of a second substrate; an upper core covering a third second planer spiral conductor formed on a front surface of the first substrate on which the insulating resin layer is formed; and a lower core covering a fourth planer spiral conductor formed on a front surface of the second substrate on which the insulating resin layer is formed. One of the upper and lower cores is formed of a metal-magnetic-powder-containing resin. The coil component includes connecting portions disposed respectively at center and outside portions of each of the first and second substrates so as to physically connect the upper and lower cores.

A masking apparatus includes a mask base body and a mask plate. The mask base body includes at least one spacer plate, and a cavity in which an electronic component can be housed. The mask plate is disposed on an upper surface and/or a lower surface of the mask base body. The mask plate includes a film-forming opening with a shape corresponding to the shape of an external structural body to be formed on an outer surface of the component. The mask plate thus allows a film-forming operation to be selectively performed on the outer surface of the component through the film-forming opening. The cavity includes, in an inner surface thereof, a film-forming groove communicating with the film-forming opening so that the external structural body can be formed at once on an upper surface and/or a lower surface of, and also on a peripheral surface of the component.

摘要:
A method for manufacturing an electronic component includes: a step of temporarily bonding a substrate to a support plate with an adhesive sheet; a step of forming a cut groove for dividing the substrate into individual chips by providing the substrate with a cut extending in the thickness direction from a second surface side, located opposite the first surface side, to a certain part of the support plate; a step of forming a continuous electrode on the second surface and on a peripheral surface located inside the cut groove, of each of the chips by sputtering, for example; and a step of detaching the chips from the support plate. An electrode on the first surface of the substrate may be formed prior to the temporary bonding step, and the electrode formed on the peripheral surface may be connected to the electrode on the first surface.

A key switch includes a base, a key top arranged above the base, a pair of link members interlocked to each other to support the key top above the base and direct the key top in a vertical direction, and a switching mechanism capable of opening and closing an electric circuit in connection with a vertical movement of the key top. Each of the link members includes an engagable end region engaged with the key top. The base includes an inner peripheral surface defining an opening capable of receiving the link members. The base is provided on the inner peripheral surface with protruding wall parts located at positions respectively facing oppositely to the engagable end regions of the link members. Each protruding wall part serves to locally reduce a clearance defined between the inner peripheral surface and the engagable region of each link member when the link member is received in the opening.
摘要:
Conductor layers 2A and insulating layers 4A are alternately stacked so as to prepare a base material 17. A plurality of grooves 18 having a predetermined width are formed in a surface of the base material 17 in such a manner that these plural grooves 18 are located parallel to each other along a stacking layer direction in order to form a coil inner peripheral portion. Embedding materials 5 are filled into the grooves 18. Surfaces 16 of the base material into which the embedding materials 5 have been filled are flattened by polishing. The conductor layers 2A located adjacent to each other are connected to each other, so that helical coils which constitute inductive elements are constructed. Then, both the front plane and the rear plane of the resultant base material are covered by an insulating layer, which is cut so as to obtain respective chips.
