45results about How to "Minimized thermal deformation" patented technology

The invention provides a polishing pad conditioner that enables stabilization of brazing metal melting point, minimization of abrasive grain detachment by uniformizing and stabilizing abrasive grain brazing condition, and enhancement of flatness by minimizing thermal deformation of the metal support. The polishing pad conditioner is fabricated by brazing multiple abrasive grains to the surface of a metal support with brazing metal, wherein the composition of the brazing metal expressed in mass % is such that 70%≦Ni+Fe≦90% (provided that 0≦Fe / (Ni+Fe)≦0.4), 1%≦Cr≦25%, 2%≦Si+B≦15% (provided that 0≦B / (Si+B)≦0.8), and 0.1%≦P≦8%.

An adaptive mirror that includes a substrate layer, on the first surface of which a reflecting layer and on the second surface of which at least one actuator is disposed. The substrate layer has a thickness of less than or equal to 1,000 μm and the mirror having at least one further metallization for thermal compensation, as a result of which a thermal deformation of the mirror is avoided or preadjusted such that the desired curvature is set as a function of the reflected power.

An indirectly heated cathode includes a cathode sleeve (2) housing a heater (1), a caplike base (3) attached onto the cathode sleeve (2), and an electron emitter layer (4) formed on a surface of the base (3). The cathode sleeve (2) is made of a metal material that contains nickel and chromium as main components and further contains at least silicon, aluminum, cerium, and lanthanum. According to this construction, the cathode sleeve (2) is kept from heat deformation. Hence a reliable indirectly heated cathode which suppresses variations in cutoff voltage can be realized.

An apparatus is disclosed for thermosetting thermoplastic tubes in a predefined shape having at least one bend. The apparatus includes an oven with an interior chamber which is heated to a temperature approaching that at which the tube thermally deforms. An elongated former has a channel dimensioned to receive the tube, and this channel has the predefined shape. A thermally absorbent coating is disposed only on a surface of the former adjacent to and extending across each bend of the former. This thermally absorbent coating locally adds the thermal energy required to reset the memory of the tube at the bend location. A conveyor extends through the oven chamber from an inlet end and to an outlet end of the oven, and the former is attached to the conveyor.

A bush bearing having an outer lubricating layer, a manufacturing method therefor and a scroll compressor having same applied thereto, according to the present disclosure, includes a bush bearing comprising: a base member which has a cylindrical shape having no separated surfaces along the circumferential direction; and a lubricating member which is formed from a material having a lower rigidity and more excellent lubricity than the base member, and has a cylindrical shape having no separated surfaces along the circumferential direction by being integrally provided to the outer circumferential surface of the base member, wherein the cylindricity of the outer circumferential surface of the lubricating member satisfies a value that is within 0.6% of the average thickness of the lubricating member, and the lubricating member has carbon fiber contained in a resin base, wherein the carbon fiber has cut surfaces exposed on both ends of the lubricating member.

An exposure method for manufacturing a liquid crystal display utilizes a scanning exposure apparatus to expose a pattern of a mask onto a glass plate. The exposure method includes a step of moving a mask stage that holds the mask in a scanning direction by a first electromagnetic actuator. The first electromagnetic actuator moves the mask stage associating with a guide member that extends in the scanning direction. The method also includes the step of moving the mask stage in a non-scanning direction different from the scanning direction by a second electromagnetic actuator. The second electromagnetic actuator moves the mask stage associating with no guide member, and a moving distance in the non-scanning direction by the second electromagnetic actuator is shorter than a moving distance in the scanning direction by the first electromagnetic actuator.
