Deburring apparatus for removing the burrs which are formed at the intersecting inner edges of at least two intersecting bores of a workpiece comprises; a frame having means for holding the workpiece; a cutter spindle borne rotatably in the frame; a cutter hinged to the leading end portion of the cutter spindle and biased to swing outwardly of the side thereof for cutting off the burrs at the inner edges of the bores of the workpiece held by the holding means of the frame when the cutter spindle is inserted into one of the bores and rotated; and a guide sleeve fitted slidably on the cutter spindle for sheathing the cutter, when the cutter spindle is inserted into or retracted out of the one of the bores, to protect the inner walls of the workpiece from damage, and for exposing the edge of the cutter to the outside when in the deburring operation. The cutter is directed along a curve of the inner edges of the bore of the workpiece by a cam on the frame engaged by a follower on the cutter spindle. A three-dimensional curve of the inner edges can be deburred precisely.

A semiconductor switching device includes first to fourth layers, a first gate portion, a second gate portion and a common gate terminal interconnecting the first and second gate portions. The first gate portion is the current control type and has a rectifying PN junction, and the second gate portion is the voltage control type. When a first polarity vias voltage is applied to the common gate terminal, the device turns on through the second gate portion, while turns off through the first gate portion when a second polarity vias voltage is applied to the terminal.

An air assisted sliding device has a pallet supported on a base. The pallet has a recess provided on the periphery of its bottom surface in which a flexible tubular sealing member is mounted. The sealing member has a memory normally contracting it so as to be flat. An air passage communicates with the interior of the flexible sealing member so that compressed air can be fed to it. A groove is evenly provided on the bottom surface of the pallet within the bounds of the recess and a separate air passage for feeding compressed air or vacuum air is communicated with the groove so that the pallet may be provided with an air film of compressed air or may be stopped and a vacuum applied to attract the pallet to the base at a predetermined position on the base. A timing belt drive or an electromagnetic motor is used.

To provide a stretched film of void-containing thermoplastic resin having an attractive force between sheets is 50 g or less. The stretched film of void-containing thermoplastic resin has no charge therein and can be processed secondarily with lesser electrostatic disturbance even in a low-humidity environment.

The vehicle-use power supply control apparatus includes a first battery supplying electric power to a load, an alternator driven by a vehicle engine, a second electric accumulator parallel-connected to the first battery, an electric power converter performing two-way power transmission between the first and second batteries, and a power supply control unit. The power supply control includes a function of setting a target power generation efficiency index, a function of setting a target power generation amount of the alternator on the basis of the target power generation efficiency index, while referring to a map defining relationship between a power generation efficiency index and a power generation amount of the alternator, and a function of controlling an amount and a transmission direction of transmission power of the electric power converter in order that an amount of electric power generated by the alternator becomes equal to the target power generation amount.

Provided are a printing paper which is made of an aliphatic polyester resin making use of a biomass raw material derived from plant resources, is excellent in running stability on a printer, substrate strength, halftone dot reproducibility, printing sharpness and water resistance and is suited for use in sheetfed offset printing, for example, commercial printing of outside posters, maps, catalogues, brochures and menus; and a label using the printing paper. The printing paper is made of an aliphatic polyester resin composition comprising from 40 to 90 wt. % of (a) an aliphatic polyester resin having at least an aliphatic diol unit represented by the following formula (I) and an aliphatic dicarboxylic acid unit represented by the following formula (II); and from 60 to 10 wt. % of (b) fine inorganic powders; and has a Gurley stiffness of from 50 to 3,000 mg, a surface area S of from 5,000 to 50,000 μm2 per 4,292 μm2 of a projected area on the surface of the printing paper, and a volume V, at a convex portion on the surface of the printing paper, of from 2,000 to 20,000 μm3 per 4,292 μm2 of a projected area on the surface of the printing paper. [Chemical Formula 1] —O—(CH2)m—O— (I) (in the formula (I), m represents an integer of from 2 to 10) —CO—(CH2)n—CO— (II) (in the formula (II), n represents an integer of from 1 to 12).
