Probe card is a part which is incorporated into a probing equipment to test finished IC chips, This card is customarily mounted with a plurality of probes, very fine needle and generally bent, and each probe is disposed so that its front end may pinpoint to a pad of an IC chip of interest. In performing the probing test, a most important condition is to keep the probe contact pressure on the pad of an IC chip at a constant position during measurement time, but in performing such at a high temperature, heated IC chips radiate the probe card and thereby positional deviation of the contact point is caused by heat expansion of the probe card and hence the contact pressure may change. The invented probe card employs a ceramic material in fabricating the probe card for possessing a very low expansion coefficient or for possessing an equivalent coefficient value to the IC chip or wafers, thereby the positional deviation of the probe contact is avoided and other devices to cope with difficulties caused by performance at a high temperature are disclosed.

A mold of crystalline silicon having a textured surface is placed on an amorphous silicon film so that projecting portions of the textured surface are in contact with a surface of the silicon film. The amorphous silicon film is then heated for crystallizing the same by solid phase epitaxy, thereby forming a crystalline silicon film having a textured surface corresponding to that of the mold.

A manufacturing method of a thin film transistor, wherein a laminated body consisting of an intrinsic amorphous silicon layer and a conductive amorphous silicon layer is formed on a glass substrate, and annealed at low temperatures not higher than 600.degree. C. thereby obtaining a polycrystalline silicon film. The conductive amorphous silicon layer gives girth to a core for polycrystallization, and therefore the intrinsic amorphous silicon layer is easily recrystallized by annealing at low temperatures.

A synchronous rotating type scroll fluid machine has a first scroll member driven by a shaft of a first motor and having an end plate and a scroll wrap protruding from a surface of the scroll end plate, and a second scroll member driven by a shaft of a second motor and having a scroll end plate and a scroll wrap protruding from a surface of the scroll end plate. The machine further has a mounting structure for mounting the scroll members such that the axes of the scroll members are offset from each other and that said scroll wraps of the scroll members mesh with each other. Thrust balancing arrangements are provided for attaining a balance between the thrusting forces acting on each said scroll member, both at the mounting structure and said scroll members. The thrust balancing arrangement includes through-bores formed in the respective motor shafts and serving as passage bores for discharging a compressed gas. This arrangement also provides cooling effect as the compressed working gas functions as a cooling medium and, in addition, serves to suppress distortion of the scroll end plate of each scroll member.

A photovoltaic device includes a monocrystalline or polycrystalline semiconductor layer of one conductivity type, a substantially intrinsic substantially amorphous semiconductor layer having a predetermined thickness small enough to avoid producing carriers therein. The substantially intrinsic, substantially amorphous layer is formed on the one conductivity type semiconductor layer, and a substantially amorphous semiconductor layer of the opposite conductivity type is formed on the intrinsic, semiconductor layer.

A scroll compressor has an orbiting scroll which operatively meshes with a stationary scroll to define compression chambers therebetween. This orbiting scroll is driven by an electric motor through a crank-shaft, and makes an orbiting movement while being prevented from rotating about its own axis by a rotation preventing member. The crankshaft is journalled by at least two sliding bearings which are arranged respectively on the both sides of the electric motor, and the mast remotely distanced bearing from the orbiting scroll has a self-aligning function which enables it to change its attitude in accordance with any inclination of the crankshaft. Further, a balance and a counter weight are provided on the crankshaft to counterbalance the centrifugal force produced by the orbiting scroll and the inertial force produced by the rotation preventing member.

A grille for air conditioning for the instrument panel of an automobile is provided which includes a main case having an opening for blowing out a wind and a plurality of curvable wind direction adjusting plates supported so as to be rotatable relative to the main case. A support member supports the distal edges of the wind direction adjusting plates. The support member has extension plates respectively extending along an extending plane of the distal edge of each wind direction adjusting plate and coupling plates coupling the extension plates with each other. Each extension plate has a groove for receiving the distal edge which is not rotatable against the extension plate. The support member is movable on a circular locus relative to the main case, the arc having a shorter radius of curvature than a span between the two edges of the wind direction adjusting plate in an unstressed configuration.

A horizontal type rotary compressor including a compression element having a cylinder, a shaft having a crank thereon, a pair of side plates concurrently serving both as bearings of the shaft and as side walls of the cylinder, a roller fitted onto the crank, and a vane so arranged as to slide in a groove of the cylinder and have a tip end thereof contacted with the roller rotating in accordance with the rotation of the crank and an appropriate end thereof urged by a spring to make a reciprocating movement along the groove are provided within a case. A pumping chamber is defined by a rear face of the vane, the groove of the cylinder and the side plates. One of the side plates is formed with a suction port capable of sucking thereinto the oil within the case while the other of the side plate is formed with a discharge port for transmitting the oil in the pumping chamber to an oil feeding passage. An oil feeder means for use in the horizontal type rotary compressor is a space provided at the exit of the suction port of the side plate having the suction port and the suction port opens downwardly so that the feeding of a sufficient or stable amount of oil is ensured even when the surface level of the oil is lowered.
