    摘要： An optical unit with shake correcting function may include a movable module having a lens, a fixed body supporting the movable module, a shake detection sensor for detecting shake of the movable module, and at least one pair of magnetic drive mechanism for shake correction which is structured on both sides of the movable module so that the movable module is swung with respect to the fixed body on the basis of detection result of the shake detection sensor to correct the shake of the movable module. The magnetic drive mechanism for shake correction is disposed so that a shake correction magnet is held by the fixed body and a shake correction coil is held by the movable module. Further, a shake correction coil may be disposed in a first region, where magnetic lines of force generated by a shake correction magnet are directed in directions generally going away from a supporting point part and/or a second region where magnetic lines of force generated by the shake correction magnet are directed in directions generally going toward the supporting point part.

    摘要： A method of forming a power transmission belt including the steps of: providing a first layer made from rubber and having first and second oppositely facing sides; providing a mold; pressing the first side of the first layer conformingly against a surface on the mold having alternating projections and recesses to thereby form alternating teeth and troughs on the first layer; locally pressing the second side of the first layer at locations coinciding lengthwise with the teeth to thereby eliminate or prevent the formation of discrete holes; and joining the first layer, having the alternating teeth and troughs thereon, to at least one other component to define the power transmission belt.

    摘要： Supplying pellets without the risk of enlarging the apparatus size or moisture absorption of the pellets by disposing a rotation drum provided with a pellet storage room in a sealed case with an inert gas supply. The apparatus according to the present invention has a main body case with a rotation drum storage part formed therein, a lid mounted on the front surface opening part of the main body case, a rotation drum disposed rotatably in the rotation drum storage part, and a pellet supply nozzle elongating from the main body. Through holes having a size capable of inserting a pellet are provided on the circumferential wall of the rotation drum with an equal interval in the circumferential direction as well as the side wall of the main body case to be contacted slidably with the circumferential wall of the rotation drum. A gas supply hole for supplying an inert gas into the pellet storage room via the through holes, and a pellet discharging hole for discharging the pellets in the through holes at the time it coincides with the pellet storing through holes according to rotation of the rotation drum.

    摘要： A method of manufacturing an arc tube having a light emitting tube portion, a first pinch seal portion, and a second pinch seal portion, all formed on a quartz glass tube. The first and second pinch seal portions are disposed on both sides of the light emitting tube portion. The quartz glass is provided almost vertically with the first pinch seal portion down. A thermal insulating plate is provided in a boundary position between the light emitting tube portion and a portion to be pinch-sealed in an outer peripheral space of the quartz glass tube. Liquid nitrogen is jetted from a cooling nozzle provided obliquely below the light emitting tube portion toward the same, thereby cooling the light emitting tube portion. The portion to be pinch-sealed is heated with a burner, and pinch-sealed with a pincher immediately thereafter.
