    摘要: A semiconductor device with a bipolar transistor that enables to realize a reliable, electric connection of an intrinsic base region with a base electrode is provided. A semiconductor substructure has a surface area. An intrinsic base region is formed in the surface area. An emitter region is formed in the surface area to be surounded by the intrinsic base region, and an emitter electrode is formed to be contacted with the emitter region. An insulator is formed to surround the emitter electrode. A base electrode is formed not to be contacted with the intrinsic base region A conductive region is formed to be contacted with the intrinsic base region and the base electrode. The substructure has a recess formed on the surface area. The conductive region is produced by supplying a conductive material to the recess to be contacted with the intrinsic base region and the base electrode. The intrinsic base region is electrically connected to the base electrode through the conductive region. The recess is preferably produced by oxidizing a part of the surface area to form an oxide and removing the oxide.

    摘要: An n type buried layer (2b) lying in the lower part of a PNP transistor (101a) is lower in impurity concentration than an n.sup.+ type buried layer (2a) lying in the lower part of an NPN transistor (100). A p.sup.+ type buried layer (4a) is formed thick on the n type buried layer (2b) and insulated from the n.sup.+ type buried layer (2a) by an isolation trench (7). A breakdown voltage at a junction of the p.sup.+ type buried layer (4a) and the n type buried layer (2b) can be improved and, accordingly, the breakdown voltage of the whole device being improved. Low-controlled collector resistance of the PNP transistor (101a) prevents an amplification factor from decreasing.

    摘要: An aspect of the invention provides an optical pickup in which an optical axis is not displaced even if ambient temperature is changed. The optical pickup of the invention has an optical unit and an optical pickup case. The optical unit has a lens member having an optical axis, and the optical axis of the lens member is offset to one side from the center of the optical unit. The optical pickup case holds the optical unit from both sides. A thermal expansion amount of the optical unit is absorbed by compression amounts of a first adhesive and a second adhesive such that the optical axis of the lens member is not displaced when the optical unit is thermal expanded.

    摘要: An ion flow recording apparatus performs recording making density modulation every pixel. When developing on a fine grain toner is to be performed using a liquid developer for an electrostatic latent image, a developing unit (developing roller) is disposed to face a direction of gravity. Namely, a control valve is provided on a pipe for application of a developer to the developing roller or on a joint portion between the pipe and a developer tank, developing units of different two colors are joined to their developer tank portions, and a rotary shaft is provided on the joint portion to be positioned at a point of symmetry to provide alternate use of the two developing units upon turning them. Therefore, developing for a plurality of colors can be simply performed, and such turning of the developing units enables prevention of the toner from deposition in the liquid developer during developing, thereby making it possible to perform a clear recording.
