Abstract: A two-tone film comprises a first paint film (4) and a second paint film (6) formed adjacent to the first paint film (4), each of the first paint film (4) and the second paint film (6) including pigment comprising a ceramic flake substrate, an inorganic thin film layer formed on the surface of the substrate, and glittering portions comprising metal dots or alloy dots formed on the surface of the thin film layer. The pigment of the first paint film (4) has a different ratio of the total areas of the glittering portions to the entire surface area of the thin film layer from the pigment of the second paint film (6). Thus, brightness of the two paint films (4, 6) are reversed between a view at the front and a view in an oblique angle.

Abstract: A process for washing a powdery and/or granular resin involves bringing the powdery and/or granular resin into contact with a washing liquid in a counterflow fashion in a tubular body with a plurality of static mixing elements disposed continuously in series, thereby removing impurities adhering to the powdery and/or granular resin and producing the powdery and/or granular resin with a less content of impurities. A washing device for use with the washing process contains an tubular body in which the static mixing elements are disposed continuously in series, and this construction is simpler than conventional ones and does not require a stirring power and mechanism to remove the impurities from the powdery and/or granular resin.

Abstract: 5 n7 A security tag is disclosed for use with an electronic security system for a controlled area. The tag comprises circuitry for initially establishing a resonant circuit (14) having a first resonating frequency within a first frequency range which is outside of the range of the detection frequency of the electronic security system. The tag is activated by changing the resonating frequency of the resonant circuit (14) to a second frequency within the detection frequency range by exposing the resonant circuit to electromagnetic energy within the first frequency range at the predetermined minimum power level to short-circuit a first circuit component (C4). The tag is deactivated by again changing the resonant frequency of the resonant circuit (14) to a third resonant frequency within a third frequency range which is also outside of the detection frequency range by exposing the resonant circuit (14) into electromagnetic energy within the detection frequency range of at least a predetermined minimum power level to short-circuit a second circuit component (C2).

Abstract: A p-type GaAs or AℓGaAs thin film is formed by a MOCVD method. In the growing step of the thin film, the thin film is doped with a high concentration of carbon atoms forming an acceptor level such that the carrier concentration of the thin film falls within the range of between 1 × 10¹⁸ cm⁻³ and 1 × 10²⁰ cm⁻³. At least one of trimethyl gallium and trimethyl aluminium is used as a raw material gaseous compound of III-group element, and arsine is used as a raw material gaseous compound of V-group element. The thin film is formed by an epitaxial growth under the molar ratio V/III of the V-group element supply rate to the III-group element supply rate, which is set at such a small value as 0.3 to 2.5, the temperature of 450 to 700°C and the pressure of 1 to 400 Torr. The thin film formed under these conditions exhibits a mirror-like smooth surface, and the film-growth rate is dependent on the supply rate of the V-group element.

Abstract: A dual action piston pump has a centrally disposed pump cylinder (12) having a pump piston (10) therein. A transition section (24) is secured to each end of said pump cylinder through which the media being pumped passes while being pumped from and to a four way valve (40). A piston rod (14, 42) is connected to each side of said pump piston (10). Each piston rod (14, 42) passes through the side wall of the transition section (24, 46) and extends into a drive cylinder (16, 44) where it is connected to a drive piston (18). The drive pistons (18) are driven by a motive fluid which may be hydraulic fluid. Each drive cylinder (16, 44) has a motive fluid connection (22, 20) adjacent to its distal and proximal ends so that both drive pistons (18) can be driven in both directions. As the pump piston (10) moves in one direction media is being pumped out on one side while media is being drawn in on the opposite side. The four way valve (40) connects one side of the cylinder (12) to a suction intake (56) and the other side of the cylinder to the discharge (58). The valve (40) reverses these connections when the stroke of the pistons reverse.

Abstract: A photosensor (20a) has a pair of n-type semiconductor layers (21U, 21D) formed on the major surface of a p-type semiconductor substrate (31). A light-shielding pattern (24) comprised of unit light-shielding layers (33) is formed on the major surface of the substrate. When the major surface is scanned by a light beam in the direction (D X ) in which the unit light-shielding layers are aligned, a couple of photo-conversion signals indicating a current position of the light beam on the photosensor are generated in the photosensor. Since the light-shielding pattern is directly provided on the sensor body, no grating glass is required other than the photosensor.

Abstract: A torsional tightener (101) is used, inter alia, for anchoring elements (108) in implants (103) anchored in bone. The tightener is releasable at a previously set torque and comprises an electric motor (406), a unit (403) changing the speed down, and a torsional tightening part. For the purpose of achieving a well-defined set torque value, the energy supply circuit of the electric motor can be interrupted at a certain current value in the energy supply circuit. The interruption and the rotational energy in the rotating parts of the torsional tightener after interruption are designed to cause a torsional tightening moment which is situated at or near an optimal or desired point on the particular moment curve for the tightening in question. Alternatively, a disconnection part is used, which interrupts the tightening function at or near the desired point on the moment curve.
