摘要:
A motor includes a turntable and a rotor holder unified with each other by insert-molding. The turntable includes a protrusion portion protruding radially outward beyond a cylinder portion and a substantially cylindrical covering portion extending downward from an radial inner end of the protrusion portion to cover an outer circumferential surface of the cylinder portion. The rotor holder has a radial outer end portion arranged in the same radial position as an outer circumferential surface of the covering portion or arranged radially inward of the outer circumferential surface of the covering portion. For this reason, a sliding contact area between a mold and the rotor holder is reduced. This helps suppress sliding contact between the mold and the rotor holder during a mold releasing process, consequently suppressing degradation of the mold.

This invention aims to provide a transparent conductive laminate excellent in sliding durability, edge-writing durability, finger writing durability and light resistance and suitable as a movable electrode substrate for a touch panel. Further, it aims to provide a touch panel using the above transparent conductive laminate. This invention is a transparent conductive laminate that is a laminate formed by laminating a polymer film, a cured resin layer-1 and a transparent conductive layer in this order, the cured resin layer-1 having concavoconvex shapes formed by phase separation of two components and containing no fine particles that impart concavoconvex shapes, and the cured resin layer-1 having an arithmetic average roughness (Ra), measured according to JIS B0601-1994, of 0.05 μm or more but less than 0.5 μm and a ten-point average roughness (Rz), measured according to JIS B0601-1982, of 0.5 μm or more but less than 2.0 μm, and a touch panel using the transparent conductive laminate.

The transparent conductive laminate of the invention is a laminate comprising a film made of a polymer with a photoelastic constant of no greater than 70×10−12 Pa−1, a light-scattering layer with a haze value in the range of 0.2-1.4% formed on one side thereof, and a transparent conductive layer formed on the other side thereof, wherein the laminate exhibits an overall retardation of λ/4. By using the laminate it is possible to provide touch panels with reduced light reflection, no coloration, excellent visibility and high reliability for outdoor use, as well as touch panel-equipped liquid crystal displays employing them.
摘要:
A transparent conductive laminate consisting of a transparent polymer substrate, an uneven cured resin layer formed on at least one side of the substrate and a transparent conductive layer formed on the cured resin layer directly or through another layer. The cured resin layer contains fine particles A having an average primary particle diameter of 0.5 to 5 μm and super fine particles C having an average primary particle diameter of 100 nm or less made of a metal oxide and/or a metal fluoride. The above transparent conductive laminate does not cause the deterioration of visibility by sparkling even when a transparent touch panel is mounted on a high-definition display and can prevent “Newton rings” which occurs between two transparent electrode substrates constituting the transparent touch panel.

A thermally-sensitive overcurrent protective relay includes a housing case, a bimetal strip bendable in response to an operating current flowing through a control circuit of the overcurrent protective relay, and a movable contact biased by a spring to form a toggle mechanism operable in response to the bending action of the bimetal. A lever supporting bracket mechanically supports the movable contact at a fulcrum portion and electrically connects the movable contact to a terminal. The terminal is mounted in the housing case to conduct current to the control circuit through a contact spring for electrically connecting the lever supporting bracket. This lever supporting member includes a trip current adjusting mechanism adapted to be rotated at its end portion by turning an adjusting screw for adjustment of the operation current.

A chucking device includes a turntable fixed to a shaft having a central axis and a cone arranged axially above the turntable. An annular yoke is arranged above a sliding portion of the cone and fixed to the shaft, and a clamp magnet is fixed to the yoke through an adhesive agent. The yoke includes an upper surface having an annular recess defined in a concentric relationship with the central axis, the adhesive agent being applied on a region of the upper surface existing radially inwards of the recess. The recess includes a radial outer wall parallel to the central axis and a radial inner wall inclined radially inwards and axially upwards. The angle between the radial outer wall and a lower surface of the clamp magnet is greater than the angle between the radial inner wall and the lower surface of the clamp magnet.
