Abstract: A refrigeration apparatus includes an outdoor unit having a first compressor and a second compressor connected in parallel with each other, a first oil separator attached to the first compressor and connected to a suction pipe of the second compressor via a first oil return piping including a pressure reducing device, and a second oil separator attached to the second compressor and connected to a suction pipe of the first compressor via a second oil return piping including a pressure reducing device. The suction pipes of the first and second compressors are connected together. The first compressor is a variable-speed compressor, and the second compressor is a constant-speed compressor. A solenoid valve selectively forming a bypass circuit with respect to the pressure reducing device, is connected in parallel with the pressure reducing device of the first oil return piping. The solenoid valve is opened when the first compressor is restarted.

Abstract: This aims to provide a diagnosing device for detecting the measurements of an electric current, a voltage and a resistance by a temperature/moisture or pressure sensor or a signal state in control means, precisely with a simple circuit constitution, for diagnosing the soundness of a circuit while simplifying a power source circuit, to suppress the cost more than the conventional circuit having no diagnosing function, and for diagnosing the signal status in the measurement or control by a measuring means or a control means. An alternating voltage generating means containing a pulse-wave voltage and an alternating current is connected with the primary side of a transformer, and a driven member such as the measuring means for any of varying electric current, voltage and resistance is connected with the secondary side.

Abstract: There is provided a pellicle in which the mask-bonding adhesive is formed to have a corner-rounded cross section in a shape akin to a trapezoid whose upper parallel side represents the face of the mask-bonding adhesive layer by which the adhesive layer is attached to the pellicle frame, and whose lower parallel side is not shorter than the upper parallel side, and the base angles of the trapezoid are 90 degrees or smaller but not smaller than 75 degrees, when the lower parallel side is assumed to be the base of the trapezoid.

Abstract: A rotation control device is configured so that a spring force of a torsion coil spring holds an attitude of a rotation body at a pre-advancement position corresponding to a post-return position (a), and a post-advancement position corresponding to a pre-return position (b), respectively. The rotation control device includes a first rotation part supporting one end of the torsion coil spring and supported on a fixed body so as to rotate as the rotation body rotates, and a second rotation part rotatably supported on the fixed body at a first rotation part side and supporting the other end of the torsion coil spring. When the first rotation part rotates, the second rotation part rotates together with the first rotation part. A wound portion of the torsion coil spring is most elastically deformed when the rotation body is at an intermediate position (c) between the position (a) and the position (b).

Abstract: An adhesive applicator forms adhesive to a smooth surface at a predetermined thickness when applied to a sheet bundle edge. An adhesive storing container is disposed at an adhesive application position, and is equipped with an applicator roller device and a scraper blade that adjusts the thickness of the adhesive layer applied. A moving device drives the applicator roller device or the sheet bundle holding device so that the applicator roller device and scraper blade move relative to the sheet bundle. The scraper blade is configured to push or sweep away excess adhesive from one end of the sheet bundle to the other end thereof across the backside, removing excess adhesive while forming a smoothly finished surface of adequately softened and flow-able adhesive.

Abstract: The present invention provides a pressure sensor and a method of manufacturing the same, which can change resistance to load smoothly in a relatively small load range and detect the pressure to the extent of relatively large load range. An uneven layer 6 is formed of a resin containing non-conductive particles 6a and having insulation properties, on a surface of the second substrate 3, and a resistor layer 7 containing at least carbon powder and having a certain film thickness is formed on a surface of the uneven layer 6. A sum of a film thickness of the uneven layer 6 between the non-conductive particles 6a and a film thickness of the resistor layer 7 is smaller than a particle diameter of non-conductive particles 6a included in the uneven layer, and at least a resistor layer 7 is formed on the non-conductive particles 6a and between the non-conductive particles 6a.

The iron-based superconducting substance includes a composition wherein an FeTe alloy is doped with sulfur in such a way as to satisfy the following formula 1. Fe(Te1-xSx)y where 0<x<1, and 0.8<y?1 ??Formula 1 The iron-based superconducting substance takes a tetragonal PbO structure with a space group P4/nmm.

Abstract: An airbag apparatus for a vehicle includes an airbag having a left airbag section and a right airbag section inflatable at left and right sides in a front area of an occupant, a retainer for retaining the airbag, and a first deployment-limiting sheet having one end coupled to the airbag or the retainer. The first deployment-limiting sheet at least partly overlaps the airbag and extends along the airbag from a rear portion to a front portion of the airbag. The first deployment-limiting sheet extends along the rear portion of the airbag during inflation thereof.

Abstract: A valve device is used by being attached to a fuel tank. The valve device includes a main body portion provided with ventilation openings which become an inner end of a connecting passage with the outside of the fuel tank, a valve body opening and closing the ventilation openings using a liquid surface of a fuel, and a skirt portion extending down from the main body portion so as to surround the valve body, and also constructed so as to admit fuel due to a pressure difference between inside and outside of the fuel tank when the liquid surface of the fuel reaches a cuff portion of the skirt portion.

Abstract: An airbag apparatus includes a gas generator that generates gas, and an airbag inflated and deployed by the gas supplied from the gas generator. The airbag restrains an occupant in a first state in which the occupant's chin is positioned on the airbag apparatus or the occupant in a second state in which the occupant's chin is positioned on a steering wheel. The airbag includes one main exhaust port, a vent cover provided to cover the one main exhaust port, and at least one sub exhaust port without a vent cover. The sub exhaust port exhausts the gas without using the main exhaust port in a state in which the vent cover blocks the main exhaust port due to a folded state of the airbag in an initial stage of an inflating and deploying operation performed to restrain the occupant in the first state or in the second state.

Abstract: A double facer that fabricates a corrugated fiberboard and that includes heat plate units having thin walls aims at improving the heat conductive efficiency to fiberboard sheets in order to enhance responsibility to the setting temperature and concurrently avoiding thermal deformation of the heat plates due to a difference in temperature between the top surface and the bottom surface.

Abstract: A card cleaning mechanism has a cleaning roller that cleans a surface of a card by contacting the conveyed card, and a roller-shaped cleaner that cleans a surface of the cleaning roller by contacting the cleaning roller. The cleaning roller is configured to move between a retreated position separated from a card conveyance path, and an operating position contacting a surface of the card being conveyed and the roller-shaped cleaner by advancing into the card conveyance path. Accordingly, the card cleaning mechanism can securely remove dust and dirt adhering to the card printing surface and does not reduce card printing quality.
