摘要:
A sound insulation member is detachably attached to a bottom of a printer main body to shield a noise in the printer main body. The sound insulation member is detached from the printer main body when an option sheet feeding apparatus is added. When the sound insulation member is not detached from the printer main body in adding the option sheet feeding apparatus, the sound insulation member enters a recess that is provided on an upper surface of the option sheet feeding apparatus.

A multistage pump according to the present invention has a plurality of intermediate casings (2) formed by press-forming a steel plate. The intermediate casing has a cylindrical side portion (21), a stage flat portion (23) with which an axial end face of an adjacent intermediate casing is held in contact, a stage side portion (24) extending axially from the stage flat portion, and a bottom portion (25) extending radially inward from the stage side portion. A relief plate (30) having an outer circumferential end face which is held in contact with an inner surface of a cylindrical side portion of the adjacent intermediate casing is attached to the bottom portion of the intermediate casing. The relief plate, the stage side portion, the stage flat portion, and the inner surface of the cylindrical side portion of the adjacent intermediate casing form a space in which an O-ring (40) is fitted.
摘要:
A method for applying a work material including the steps of intermixing the work material with a flowable carrier substance to form a flowable applying medium consisting of the work material and the carrier substance; and housing the applying medium in a container selectively operable to permit release of the applying medium from the container for receipt on a target spaced therefrom. An apparatus for applying a work material including a container having an internal chamber communicating with the exterior of the container through an aperture, a mechanism mounted on the container for selectively opening and closing the aperture, and an applying medium housed within the chamber of the container having a consistency permitting release through the aperture of the container toward a target spaced therefrom upon operation of the mechanism.
摘要:
A method for manufacturing a wiring board comprising an insulating member, comprising: a penetrating hole formation process of forming a penetrating hole in the insulating member; a placement process of inserting a conductive connecting particle into the penetrating hole; a connecting particle pressing process of disposing the conductive layers on both surfaces of the insulating member, pressing the conductive layers toward the connecting particle in the penetrating hole, and deforming the connecting particle in the pressing direction to obtain the connecting member; and a patterning process of patterning the conductive layers, wherein, in the connecting particle pressing process, the pressing is performed such that the cross-sectional area in the direction along the insulating member surface of at least a portion of the connecting member is greater than the contact area of the connecting member with the conductive layers.
摘要:
A photoelectric back plane board is provided to facilitate the relative positioning of an optical data bus and light emitting/receiving devices, interconnection of a circuit board for optical communication and respective elements, and supplying power and inputting/outputting signals to/from the printed circuit board. In the photoelectric back plane board, the optical data bus is inserted into a recess within an optical data bus fixing board and a connector holding light emitting/receiving devices is positioningly fixed to the fixing board via through holes H formed in the fixing board so that relative positioning of the signal light incoming/outgoing areas and the light emitting/receiving devices can be easily achieved. By mounting the fixing board on a printed circuit board on which an electrical connector is provided, interconnection of a circuit board mounted on the optical connector and the printed circuit board is achieved by means of the electrical connector.
