摘要:
The present invention concerns an aqueous resin dispersion comprising a copolymer of a perfluoroalkyl group-containing ethylenically unsaturated monomer and/or polydimethylsiloxane group-containing ethylenically unsaturated monomer and another ethylenically unsaturated monomer copolymerizable therewith dispersed in water in the presence of a water-dispersible polyurethane containing a polydimethylsiloxane group such as silicone and a hydrophilic group such as a carboxylate group. The aqueous resin dispersion of the present invention provides a release agent which can freely control releasability, be excellent in adhesion to a substrate, and undergo little migration to back face or little change in releasability with time.

In the primary invention of this application, an optical-fiber inspection device which detects the distance to a reflection point within the DUT and the amount of reflected light by dividing into two a laser beam which is possible to be frequency-swept, making one of the divided light beams incident to an optical detector via the reference light path, while making the other of the divided light beams incident to the DUT and making the light reflected within the DUT incident to the said optical detector, and analyzing the frequency of the interference signal for the two beams obtained by the optical detector, is configured so that the final reference light is obtained by providing an optical coupler in the reference light path and, after taking out a part of the reference light and making it pass through an optical frequency shifter, combining this again with the original reference light with the said optical coupler.
摘要:
A process for preparing storable vegetable juice comprising crushing vegetables to extract juice, adding an organic acid to the vegetable juice, and treating this vegetable juice with a weakly basic anion exchange resin on which an organic acid has previously been adsorbed and a food containing a vegetable juice prepared by the process. The process can produce vegetable juice which can be stored at room temperature, produces no bad odor when stored at room temperature, and is free from a resin odor which has been unavoidable when a weakly basic anion exchange resin was used.
摘要:
An apparatus for synchronously controlling the actual operation of a machine using one or more motors, such as servo motors, by simulating in program form a combination of selectable machine mechanisms, including drivers, connecting shafts, clutches, gears and cams. Each such machine mechanism is represented by a virtual mechanism, preferably as a software module that contains information uniquely identifying the module, operation information that defines the generation of position information and connection information that defines other modules to which connection is made. The software modules comprise drive modules for generating position information, transmission modules for simulating the transmission mechanisms and output modules for outputting motor commands.

A brightening chemical polishing solution for a hardened steel article (e.g., a carburized and quenched gear) comprises hydrofluoric acid having a molar concentration of from 0.2 to 2 mol/l, hydrogen peroxide having a molar concentration of from 0.4 to 4 mol/l, and water, a molar ratio of the hydrofluoric acid to the hydrogen peroxide being from 1:1.5 to 1:2.8. The steel article is quench hardened and is chemically polished in the solution. A shot-peening is additionally performed, prior to the polishing.
摘要:
An interconnect structure in a semiconductor device has a metal layer of an Au type formed at a contact hole region on an electrode or a resistor element containing tungsten (W) and an interconnect connected with the electrode or the resistor element through the metal layer. Since the metal layer of a compound such as Au which has selectivity in terms of etching rate is formed as an etching-stop layer in the contact hole region of such as WSiN or WSi which has no etching selectivity with respect to an interlayer insulating film of SiO.sub.2, it is possible to form contact holes on the resistor elements of WSiN or the electrodes of WSi simultaneously with those on other electrodes containing Au and to prevent the resistor elements of WSiN or the electrodes of WSi from being etched through.

A hydraulic clutch (40) for u se in an automotive automatic transmission includes a clutch drum (41) having a hydraulic pressure chamber (43), a piston (42) movably fitted in the clutch drum (41) in covering relation to the hydraulic pressure chamber (43), a pressure plate (45) disposed in confronting relation to a surface of the piston (42) remotely from the hydraulic pressure chamber (43), and interleaved drive and driven plates (46, 47) disposed in confronting relation to a surface of the pressure plate (45) remotely from the piston (42). The drive and driven plates (46, 47) are engageable with each other by the pressure plate (45) pressed by the piston (42) moved in response to a hydraulic pressure supplied to the hydraulic pressure chamber (43). An assisting member (44) is disposed between the piston (42) and the pressure plate (45) and comprises an annular array of rigid assisting levers (44a) and a retaining plate (44b) holding the assisting levers (44a) together. The assisting member (44) has a radially inner and pressable by the piston (42), a radially outer end held in engagement with the clutch drum (41), and a radially intermediate region engageable with a projection (45a) of the pressure plate (45). The assisting lever serves (44a) as a lever with the radially outer end as a fulcrum for boosting the force applied from the piston (42) and transmitting the boosted force to the pressure plate (45).

摘要:
A scroll-type compressor has a stationary scroll and a moving scroll which is orbitted about the center of the stationary scroll. A valve chamber, a first by-pass, and a second by-pass are formed in the end plate of the stationary scroll. The first by-pass communicates between the inside of the valve chamber and one of the compression chambers formed by the scrolls, and the second by-pass communicates between the inside of the valve chamber and the outside of the end plate of the stationary scroll. The valve chamber houses a plate-shaped valve which is moved by fluid pressure between a closed position, in which it blocks the by-passes, and an open position, in which working fluid can flow between the two by-passes. Working fluid at either discharge pressure or suction pressure can be introduced into the valve chamber to the rear of the valve through a connecting pipe which is connected to the valve chamber and a 3-way solenoid valve.
