摘要:
A duplex pallet for the transport or storage of articles of the present invention has a deck surface easily switchable between a configuration matching with, e.g., the ISO (International Standards Organization) standards and a configuration matching with, e.g., JIS (Japanese Industrial Standards). While the deck surface is held in the configuration matching with the ISO standards, a hook and a contact guide are respectively released from a clamp post and a pallet body so as to release one longer edge of a movable deck from one shorter edge of the pallet body. Subsequently, the movable deck is rotated away from the pallet body by 90 degrees, then shifted inward, and then further rotated in the same direction by 180 degrees until the hook mates with another clamp post. At the same time, another contact guide is inserted into a space between an upper deck and a lower deck. In this condition, one longer edge of the pallet body and the other longer edge of the movable deck contact each other, implementing the configuration matching with JIS.

A polishing agent used for polishing a silicon wafer is composed of a colloidal silica polishing agent containing an ethyl silicate monomer and/or an ethyl silicate polymer. Even when the polishing agent is used with a rigid polishing pad, it is able to provide a polished wafer having an excellent flatness and whose surface has a roughness comparable to that obtained by the conventional final polishing process.

A device for vibrating a workpiece to be processed, serves as a workpiece table to be used to processing the workpiece by means of a rotating tool having a grindstone. The device comprises a table for supporting the workpiece and a base to be detachably furnished to the table of a processing machine. The table is supported on the base via a plurality of piezoelectric actuators each of which is connected electrically to an external controller for vibrating the workpiece being processed by actuating selectively a driving voltage from the controller. The piezoelectric actuator is a laminated piezoelectric element, at least one end of which is secured to the base.

A machining tool is provided with an electric discharge truing/dressing apparatus comprising a spindle stock for containing and supporting a workpiece spindle which is driven for rotation while holding a workpiece or an electrode; a tool rest which moves parallel and perpendicular to the spindle of the spindle stock and holds an electrode machining tool and a grinding wheel; a feed electricity means disposed between a workpiece supporting portion of the spindle and the tool rest; a magazine disposed at an outside area of a machining area of the tool rest and adapted to store the workpiece and the electrode; and a loading device disposed between the magazine and the spindle. The grinding wheel on the tool rest is subjected to truing/dressing by feeding the electrode from the magazine to the spindle stock.
摘要:
A secondary air supply system for an internal combustion engine for suppressing combustion when a throttle valve is fully closed. A secondary air supply system is controlled with a microprocessor which controls other circuits such as the vehicle ignition circuit. Sensors provide outside air temperature data, internal pressure and engine rpm to the microprocessor. The microprocessor addresses the memory based on a computation including these sensed values. The memory in turn controls valves in a secondary air supply system.

The inventive cement-based composition is useful as a coating material for corrosion-resistant protection on steel and iron surfaces. The composition is basically a polymer cement composition prepared by compounding a hydraulic cement with an aqueous emulsion of a polymeric constituent but characteritically the inventive composition is prepared by adding an aqueous emulsion of a hydrocarbon solvent such as kerosene containing a combination of surface active agents, i.e. oil-soluble non-ionic, water-soluble non-ionic and water-soluble cationic ones, and a saccharide compound such as glucose. By virtue of the unique formulation, the composition has a greatly extended pot-life suitable for coating works of, for example, steel rods and pipes by the dip coating method.

As a grinder is being rotated, an outer circumference thereof and a metal block of raw material are pressed at determined speed or under determined pressure, and the grinder cuts the block on its surface so as to generate short metal fibers of not more than about 15 .mu.m calculated as diameter and not more than about 400 .mu.m in length by contacting between each of abrasive grains held in a matrix of the grinder and the surface of the raw material.
