Abstract: A confocal microscope unit according to an embodiment includes: a first subunit which includes a light source, a pinhole plate, and a photodetector; a second subunit which includes a light source, a pinhole plate, and a photodetector; a scan mirror which scans excitation light output from the first and second subunits on a sample via a microscope optical system and guides fluorescence generated from the sample in response to the excitation light and focused by the microscope optical system to the first and second subunits; and a main housing which is attachable to a connection port and to which the scan mirror, the first subunit, and the second subunit are fixed, wherein the first subunit and the second subunit are disposed in the main housing so that incident angles of two excitation lights to the scan mirror are displaced from each other by a predetermined angle.

Abstract: Embodiments are for a confocal microscope unit attached to a connection port of a microscope including: light sources which output irradiation light to a sample to be observed; photodetectors which detect observation light generated from a sample in response to the irradiation light; a scan mirror which scans the irradiation light on the sample and guides the observation light generated from the sample to the photodetectors; a scan lens which guides the irradiation light scanned by the scan mirror to the microscope optical system and guides the observation light focused by the microscope optical system to the scan mirror; a lens barrel to which the scan lens is fixed; an attachment portion which attaches the lens barrel to the connection port; and a movable portion which supports the lens barrel so that an angle of the lens barrel with respect to the attachment portion is changeable.

Abstract: A coating composition comprises: (a) a resin solution containing a polyamide-imide resin and a solvent having a urea bond; and (b) a powdered solid lubricant. In general, the coating composition containing a polyamide-imide resin does not raise any concern about reproductive toxicity and has excellent lubrication durability.

Abstract: A compressor includes a swash plate, and a shoe connected to an outer periphery of the swash plate. A surface of the swash plate slides upon a flat surface of the shoe. A sliding film is applied to the surface of the swash plate. The sliding film is formed of binder resin which contains a solid lubricant and titanium oxide powder. This allows the surface of the swash plate and the flat surface of the shoe to smoothly slide upon each other.

Abstract: A Chromium VI-free coating composition comprises a binder and a corrosion inhibitor in a solvent, wherein the binder comprises a silicate and an organic titanate, and the corrosion inhibitor comprises aluminium particles and zinc particles preferably flakes. The composition may also comprise an anti-corrosion additive which comprises a metal phosphate, a lubricant which comprises a polyolefin wax, and/or a thickener. The coating composition is useful for coating substrates such as nuts, bolts and other fasteners, door, bonnet and boot lock parts, hinges, door stoppers, window guides, seat belt components, brake rotors and drums, and other transportation industry related parts.

Abstract: A coating composition for use in sliding members contains a polyamideimide resin and a solid lubricant and is prepared by mixing these ingredients. The polyamideimide resin is a substance having a glass transition temperature of 270° C. or above or a substance having a tensile strength of 200 MPa or more at room temperature. The sliding film made of the coating composition for use in sliding members is provided with a satisfactory sliding property.

Abstract: A coat layer formed on the outer perimeter side surface of a piston comprises a fluorocarbon resin and a binder as main components, and further contains 0.05-12% by volume of a wear resistance additive with a Mohs hardness of 2.0-5.0. This provides a piston compressor piston having a coat layer with excellent wear resistance.

Abstract: The present lubricant compositions comprise a mixture of graphite, molybdenum disulfide and polytetrafluoroethylene in specified proportions within a matrix of an organic resin. When applied to surfaces that are in sliding contact with one another the compositions exhibit high wear resistance, good initial conformability, and a coefficient of friction following use that is lower than the initial coefficient of friction. The compositions are particularly suited for application to engine pistons.
