For resistance-welding workpieces of metal, an electrode is pressed against superposed regions of the workpieces and an electric current is supplied to the superposed regions to heat the same due to an electric resistance of the workpieces. The electrode has a body having a tip end for pressed engagement with one of the workpieces, and a matrix of tapered teeth disposed on the tip end of the body except for a center of the tip end. The teeth define recesses therebetween. One of the recesses is positioned at the center of the tip end, and the teeth are progressively higher from an outer circumferential edge of the tip end toward the center thereof.

A method of producing a molded ceramic article comprises the first step mixing powdery raw materials and a liquid additive, thereby obtaining a mixed raw material, the second step press-molding the mixed raw material obtained in the first step in a hydrostatically applied condition of pressure, thereby removing an excess of the liquid additive to obtain a preform, and the third step calcining the preform obtained in the second step to obtain a molded ceramic article. The molded ceramic article comprises, as a principal component, copper and, as essential components, Cr and Ni within composition ranges of 0.1.ltoreq.Cr

摘要:
A molded article formed of a composition including 100 parts by weight of at least one kind of resin selected from the group consisting of thermoplastic resins and thermosetting resins, and 0.01 parts by weight to 10,000 parts by weight of a silylated polyolefin, which is obtained by a reaction between a silicon-containing compound containing a structural unit represented by Formula (1) and a vinyl group-containing compound having a defined number average molecular weight, a derivative thereof, or a mixture of these, —Si(R1)H—Y1— (1) wherein R1 and Y1 are defined and with the proviso that the silylated polyolefin is not obtained by a reaction between a silicon-containing compound containing a structural unit represented by Formula (1) and having two or more SH groups per molecule and a compound having 2.0 or more vinyl groups on average per molecule as the vinyl group-containing compound.
摘要:
A digital copier using a laser card or like external storing medium for storing image data. A remaining amount of memory capacity of a laser card is displayed in terms of the number of papers of a particular size or by percent. Based on the remaining amount of capacity, image data are compressed and reduced, the reduction ratio being also recorded in the card. When the contents of a series of documents cannot be accommodated in a single card, the first card is provided with a mark which shows that the second card is to follow.

摘要:
According to one embodiment, a wafer prober for conducting a backside analysis on a wafer is provided. The wafer prober includes a wafer stage and a movable plate. The wafer stage includes surface and back opposed in a thickness direction, a concave portion provided at the surface which supports the wafer, and a first through hole which passes through a bottom face of the concave portion in the thickness direction in the concave portion. The movable plate is accommodated in the concave portion of the wafer stage. The movable plate is movable in a direction parallel to a top face of the wafer stage. The movable plate has a thickness equivalent to a depth of the concave portion of the wafer stage. The movable plate has a second through hole. The second through hole passes through the movable plate in a thickness direction. The second through hole is smaller than the first through hole. The second through hole communicates with the first through hole.
摘要:
A novel cassette changer for a tape player wherein a tape cassette accommodating member and a tape driving mechanism are fixed relative to each other during selection of a tape cassette and which has a comparatively small overall size and requires a comparatively low power for moving a tape cassette between the tape cassette accommodating member and tape driving mechanism. The cassette changer comprises a plurality of cassette receiving members each for removably receiving a tape cassette thereon, an accommodating member for receiving the cassette receiving members in a row thereon, an actuating means for selectively moving a cassette receiving members from a home position to a transfer position, a tape driving mechanism mounted in a fixed relationship with respect to the accommodating member for receiving a tape cassette thereon and driving a tape of the tape cassette, and a carrier for receiving a tape cassette from the selected cassette receiving member moved to the transfer position and setting the tape cassette in position onto the tape driving mechanism.
