Abstract:
A brushless motor has a stator, a rotor rotatably disposed in an inner circumferential portion of the stator, and a resolver configured to detect a rotational position of the rotor with respect to the stator. The resolver has a resolver stator disposed at a fixed circumferential position with respect to the stator, and a resolver rotor disposed at a fixed circumferential position with respect to the rotor.
Abstract:
A liquid crystal display device having a built in touch screen including a first substrate having pixel units comprising: a plurality of pixels displaying an image and sensor regions having light sensors formed adjacent to the corresponding pixel units to sense a position of a contacted object; a second substrate disposed on the first substrate, comprising: color filters formed on regions corresponding to the pixel units and first black matrices formed on regions corresponding to the sensor regions of the pixel units; a liquid crystal layer interposed between the first substrate and the second substrate; and a backlight assembly disposed on a bottom portion of the first substrate and providing light to the first substrate and the second substrate. The liquid crystal display device with the built in touch screen determines a point of contact on the touch screen.

Abstract:
This invention is to offer the metal mold for injection molding and the metal mold for diecast molding with an excellent temperature controlling property that can be manufactured with lower manufacturing cost and shorter manufacturing time. The purpose of this invention is to offer the method to use the metal mold for injection molding capable of producing accurate products. The metal mold 1 for injection molding has the fixed metal mold part 2 configured by processing, layering and bonding a plurality of metal plates 10, the movable metal mold part 4 configured by processing, layering and bonding a plurality of metal plates 13, and the temperature controlling passages 3 and 5 formed by processing, layering and bonding a plurality of metal plates 10 and 13 in at least, one of the fixed metal mold part 2 and the movable metal mold part 4.
Abstract:
A piston for an internal combustion engine comprises at least a pair of ribs arranged between an inner surface portion of a skirt and side portions of pin bosses. The ribs are symmetrical with respect to a thrust center line of the piston and have in a longitudinal direction thereof a center line which is positioned to be lower than an axis of a piston pin.
Abstract:
An abrasion and scuff resistant piston comprises a piston main body of aluminum alloy, a ring groove for retaining a piston ring, an abrasion resistant nickel plate layer covering at least the ring groove, a piston skirt, also of aluminum alloy and an abrasion resistant steel plate layer covering the lower outer circumference of the piston including the piston skirt.
