摘要:
There is provided an insulated wire including: a conductor wire; and a polyamide-imide insulation coating formed around the conductor wire, the polyamide-imide insulation coating being made from a polyamide-imide resin based insulating varnish, the varnish being synthesized by reaction of an isocyanate constituent and an acid constituent in a solvent, the isocyanate constituent including 5 to 50 mol % of 2,4′-diphenylmethane-diisocyanate having a flexible molecular structure.
摘要:
A varnish for a partial discharge resistant enameled wire includes an insulating varnish, and an organosol including an inorganic fine particle comprising a metal oxide fine particle or a silicon oxide fine particle. The organosol is dispersed in the insulating varnish. The inorganic fine particle includes a hollow portion therein.
摘要:
A poppet valve in an internal combustion engine comprises a valve head and a valve stem. On a valve face of the valve head, a hardened layer of dendrites in which crystals are directed from the inside to the surface is formed, thereby increasing wear resistance of the valve face without cladding.
摘要:
There is provided a insulated electric wire with an electric conductor on which at least a lubricating layer is formed, in which a lubricant is added to the lubricating layer so that granular bodies, with sizes of 5 nm to 3 μm, which are formed by coagulation of the lubricant disperse on a surface of the lubricating layer.
摘要:
An insulating coating composition that improves lubricity without reduction of the varnish adhesion strength and an insulated wire using the insulating coating composition, and a coil using the insulated wire are provided. An insulating coating composition comprises a polyamide-imide resin, which is obtained through a synthetic reaction of isocyanate component with acid component, and a lubricant component, wherein the terminal isocyanate group of the polyamide-imide resin is capped with a blocking agent of higher alcohol having a carbon number of eight or more.

摘要:
An insulated electric wire is composed of a conductor, and a lubricating layer containing a lubricant. The lubricating layer is formed around the perimeter of the conductor. The lubricating layer is not less than 0.06 and not more than 0.12 in an absorbance ratio A1/A2 expressed by an absorbance A1 of carbon-hydrogen stretching vibration and an absorbance A2 of benzene ring framework vibration, obtained by Fourier Transform Infrared Spectroscopy analysis of a surface of the lubricating layer.
摘要:
An analyzing system, comprising: a sample processor for processing a sample based on a designated dilution parameter; a measurement section for measuring the sample processed by the sample processor; a dilution parameter memory for storing a first dilution parameter and a second dilution parameter which is different from the first dilution parameter and can be supplied by a user of the analyzing system; and a measurement controller for controlling the sample processor and the measurement section so as to process the sample based on the first dilution parameter and obtain a measurement value by measuring the processed sample; wherein, when a comparison of the measurement value and a predetermined threshold indicates a retest, the second dilution parameter is used for the retest, is disclosed. A diagnostic processing device and computer program product thereof are also disclosed.
