An immersion oil for microscopy is produced by blending 10 to 90 parts by weight of chain hydrocarbon having 200 to 5,000 of molecular weight and 10 to 90 parts by weight of specific diphenylmethane derivatives or bis(.alpha.-alkylbenzyl) alkylbenzene derivatives or 2,4-diphenyl-4-dimethylphenylbutane derivatives.The product obtained has excellent values in the various properties such as light dispersion, refractive index, viscosity and the like. Furthermore, it has an excellent advantage that the properties such as Abbe's number and the like are easily adjustable.
摘要:
A method of manufacturing low energy-loss waveguide circuit elements in which a film of metal with a low resistivity is joined to a base metal by thermal pressing or electric plating, and a hard male die of a desired shape is pressed into the base metal from above the metal film, whereby a plastic strain is caused in the base metal thereby to form a recessed portion in the base metal having an internal surface covered with the low resistivity metal.

A semiconductor device includes one or more transistor cells mounted on a first conductive type silicon carbide (SiC) substrate, wherein each of the transistor cells includes a second conductive type wall region formed on a first surface of the SiC substrate, a first conductive type source region formed in the wall region, a gate electrode formed with a gate insulating film; a source electrode formed in such a way as to be brought into contact with the source region, and a drain electrode formed on a second surface of the SiC substrate. The semiconductor device further includes a second conductive type region located close to an outside of an outermost cell of the transistor cells, the second conductive type region surrounding the wall region and being insulated from both of the gate electrode and the source electrode.

A main shaft has a shaft cylindrical portion extending from an outer periphery of a large-diameter portion. A drum has a drum cylindrical portion extending from an outer periphery of a drum plate portion. An axial forward end of the drum cylindrical portion is arranged in an inside of the shaft cylindrical portion. A frictional engagement unit of a clutch is provided in an inside of the shaft cylindrical portion. A motor generator has a rotor, which is firmly fitted to outer walls of the large-diameter portion and the shaft cylindrical portion and rotatable relative to a stator. A working-oil supply passage is formed in an inside of an input shaft.

When an arriving electric vehicle arrives at a car park with parking spaces, a parking state detection means in a parking and power charging system detects the presence of empty parking spaces. An assignment means assigns a ranking of charging performance to each detected empty parking space so that the empty parking space having the charging device of a higher charging performance has a higher ranking of charging performance on the basis of descending order of charging performance of the charging devices. A communication means obtains vehicle parameters of the arriving electric vehicle. A parking space instruction means instructs the arriving electric vehicle to move to and be parked in the empty parking space having the ranking of charging performance selected on the basis of the vehicle parameter such as necessity to charge or degree to easily charge the on-vehicle battery mounted on the arriving electric vehicle.
摘要:
A semiconductor device includes one or more unipolar compound semiconductor element; and bypass semiconductor elements externally connected to the respective compound semiconductor elements in parallel. A turn-on voltage of the bypass semiconductor elements is smaller than a turn-on voltage of the compound semiconductor elements in the direction from the source to the drain.

The invention provides a flattened heat pipe whose vapor flowing passage is not clogged and which has an excellent capillary force. The flattened heat pipe has a closed container formed by flattening a tubular container, a plurality of wick structures arrayed within the container in a longitudinal direction so as to form an acute-angled portion where a capillary force is large at least partially within the container, a hollow portion formed of an outer peripheral surface of the wick structure and an inner wall surface of the container and a working fluid sealed into the container.
摘要:
An apparatus for transferring a pattern of minute surface structures, using a pair of press members which are located opposingly for movements toward and away from each other. One press member is adapted to support thereon a mold having on a transfer surface a master pattern of minute structures to be transferred, while the other press member is adapted to support thereon an annular substrate plate having a curable resin layer coated thereon and to press the resin layer against the transfer surface of the mold to transfer said minute structures to the resin layer. The mold is provided with a circular center hole defining at least three small-diameter segments and three large-diameter segments alternately and at uniform angular intervals along an inner periphery of the mold. The annular substrate plate has an inside diameter exactly matching with the small-diameter segments at the inner periphery of the mold.

摘要:
An imaging module includes an imaging substrate mounting an imaging device thereon, a substrate holding plate, a holder. The substrate holding plate includes four substrate securing portions for securing the imaging substrate that are located opposing to four corners of the imaging substrate, respectively, an opening portion surrounded by the four substrate securing portions, and four holder securing portions that are located outwardly from the four substrate securing portions in a longitudinal direction thereof, respectively. The holder is formed integrally with a lens support barrel configured to support a lens unit at an inside thereof, and has plate securing portions configured to secure the holder securing portions at positions opposed to the holder securing portions of the substrate holding plate, respectively. The imaging module causes little residual compressive stress left in the imaging substrate, so that it can acquire high-resolution images.
