Abstract: A seal member is attached to a cover which occludes a gear case as a housing unit. The seal member is formed of elastomer and integrally formed with: a plate-shaped portion formed into a disc shape which covers the inner surface of the cover; an inner seal portion which is positioned on the inner peripheral edge of a through-hole, and comes into sliding contact with the outer peripheral surface of an output member; an outer seal portion which is positioned on the periphery of the cover, and comes into contact with the opening end of the housing unit; and anchor portions which latch onto the front surface of the cover via mounting holes provided to the cover. The boundary between the seal member and the cover extends only to the outside of the gear case, and does not extend to the inside of the gear case.

Abstract: A heat sink (35) is fixed by insert molding to a resin-made motor cover covering a case body fixed to a motor body. A flow-in portion (61) extending along a straight line and branch portions (62) to (66) formed so as to be branched to the flow-in portion (61) are formed in the heat sink (35), a tip portion of a power-feeding terminal (58) is disposed at the branch portion (62), and the tip portion of the power-feeding terminal (58) is disposed at the branch portion (63). In addition, when a molding resin is cast in the flow-in portion (61) and the branch portions (62) to (66) during the insert molding, these power-feeding terminals (58) and (59) are fixed to the branch portions (62) and (63) and terminal parts (58b) and (59b) are positioned by the branch portions (62) and (63).

Abstract: A planographic dry offset master plate composed of a substrate and, formed thereon, a crosslinking agent-cured layer of a diorganopolysiloxane in which 5 to 40 mole % of the organic groups directly bonded to silicon atoms are phenyl groups. The master plate is especially suitable for plate-making by an electrostatic process and a direct image process. The resulting printing plate has good durability and are free from scumming during printing.

Abstract: An electrostatic recording element comprising a conductive layer and a surface layer electrostatically chargeable upon application of an electric field, said surface consisting of an upper recording layer and a lower insulating layer, and said recording layer containing highly insulating hydrophobic resin and an elevated amount of inorganic or organic pigment whereas said insulating layer either consisting solely of highly insulating hydrophobic resin or containing only a small amount of said pigment together with said resin which is scribable or stampable with water-soluble ink without deteriorating the recording characteristics and is at the same time capable or preventing fingerprints, and which can further be utilized as a lithographic printing plate.
