The invention provides a method for manufacturing electrolytic capacitors. Electrode lead terminals in a number not less than three are attached to a cathode foil and an anode foil. The electrode lead terminals include at least one cathode lead terminal attached to the cathode foil and at least one anode lead terminal attached to the anode foil. A winding core having an axis is prepared. The cathode foil and the anode foil are wound around the winding core, being overlapped each other. A cross section of the winding core perpendicular to the axis includes an outer edge having a portion along each side of a polygon with the above number of sides. Thereby, a method for manufacturing an electrolytic capacitor capable of suppressing displacement of a lead terminal can be provided.

Provided is a bearing structure, which can be simply worked and lowered in its manufacturing cost. The bearing structure (1) comprises a housing including a first housing portion (13) having a recess of a substantially semicircular section and a second housing portion (14) having a recess of a substantially semicircular section and forming a supporting hole (16) of a substantially circular section together with the recess (13a) of the first housing portion (13). Further comprised are two halved roller bearings (2) having a shaft (12) fitted therein. The two halved roller bearings (2) include one set of two halved outer rings (3a and 3b) arranged closely in the supporting hole (16) of that housing, a plurality of rolling elements (4) arranged to roll on the individual inner sides faces of the two halved outer rings (3a and 3b), and one set of two halved retainers (5a and 5b) for retaining the individual rolling elements (4) arranged substantially equidistantly in the circumferential direction. The internal diameter of the supporting hole (16) in the direction of the mating faces of the housing portions is made larger than the internal diameter in the direction displaced by 90 degrees from that of the mating faces.

An optical scanner for an image forming apparatus has a housing having a wall surface provided with a through-hole, and an optical scanning unit, which is provided within the housing, scans light on an object to be scanned in order to form an image on the object to be scanned, and includes: a polygon motor; a polygon mirror that reflects the light while being rotated by a driving force of the polygon motor; a mirror member that reflects the light reflected by the polygon mirror, toward a target object; and a mirror holding member that is attached to the wall surface of the housing and holds the mirror member. The mirror holding member has a heat radiation part that is exposed to the outside of the housing through the through-hole. Thereby, heat radiation of the mirror holding member is prevented, and position shift of the mirror holding member caused by the heat radiation is prevented, and then the optical scanner can proceed normal function.

The invention provides an inspecting device. The inspecting device is provided with a moving part, a pressing part, a positioning part, a declining part and a rising part. The moving part can move between an inspecting position for inspecting a substrate and a loading and unloading position for loading and unloading the substrate. The pressing part goes down from the upper side of the moving part which is on the inspecting position to a declining position, and presses the substrate to the moving part. When the pressing part presses the substrate to the moving part, the positioning part positions the moving part at least in the moving direction relative to the pressing part. When the moving part is on the inspecting position, the declining part goes down from the upper side of the inspecting position independently relative to the pressing part on the declining position. The declining part is provided with a first contact part, and the first contact part is electrically contacted with a first contacted part arranged on the upper surface of the substrate. When the moving part is on the inspecting position, the rising part rises from the lower side of the inspecting position independently relative to the pressing part on the declining position. The rising part is provided with a second contact part, and the second contact part is electrically contacted with a second contacted part arranged on the lower surface of the substrate.

The invention provides a feed unit and an image forming apparatus therewith. A feed unit stackable with another feed unit in the up-down direction includes a unit body and a storage cassette. The storage cassette has a cassette body in which a recording medium is stored, and is removably inserted in the unit body. The unit body has a positioning member projecting from its top face to serve to position another feed unit loaded on the feed unit. The storage cassette has a side cover forming a part of the exterior face of the feed unit. The side cover has a fitting part extending toward the top face of the unit body, and in the fitting part, an engagement recess is formed with which the positioning member engages so as to position the storage cassette relative to the unit body.

Provided are: a workpiece unit (10) that makes it possible to attach a holding member (1) to a workpiece body (1) at a suitable position and that minimizes displacement of the holding member (2) after attachment thereof; and a method for producing the workpiece unit (10). The workpiece unit (10) is provided with a workpiece body (1) and a holding member (2) arranged on at least a part of the outer circumference (1c) of the workpiece body (1). The workpiece body (1) comprises at least one first positioning section (1d) on a part thereof that faces the holding member (2). The holding member (2) comprises a second positioning section (2d) that engages with at least a part of the first positioning section (1d).

Plugs (30) are formed of a material that has a greater total content of Al, Fe, B, Si, and free carbon than the material for a ho
