摘要:
An AC exciter and a main AC generator are mounted on a common rotating shaft of an engine, and a power rectifier and a power inverter are connected in series to the output of the main AC generator. In starter mode, an external AC power source is connected by a switch to the input of the power rectifier, and the output of the power inverter is applied to an armature winding of the main AC generator to drive it as a nocommutator motor to start the engine. A permanent magnet AC generator is also mounted on the common shaft of the engine to provide DC excitation to the AC exciter after converting the output of the permanent magnet AC generator into DC current, and the output of the permanent magnet AC generator is further utilized to detect the rotational speed of the engine to control the switch.

A spindle motor, comprising a base having a cylindrical drawn portion formed by plastic working, a sleeve that is inserted in the drawn portion, a shaft that is inserted in a state of being rotatable relative to the sleeve, and a lubricant that fills the gap between the sleeve and the shaft, in which the sleeve is affixed with an adhesive agent to the drawn portion inner periphery, wherein there are adhesive reservoirs around the inner periphery of the drawn portion. These adhesive reservoirs are formed during a series of plastic working steps in which the cylindrical drawn portion is formed.

A folding apparatus of the present invention comprises a folding section 40 for folding a web W in two so that opposite side edges W1, W2 of the web W are in a predetermined positional relationship with respect to each other; a correction section 90 for correcting a moving direction of the web W by contacting the web W in the folding section 40; a detecting section 41, 103 for detecting a reference portion W1, W2 of the web to be used as a reference in a web folding operation so as to output positional information regarding a position of the detected reference portion W1, W2; and a control section 3 for controlling the correction section 90 based on the positional information so as to change a state of contact of the contact of the correction section 90 with the web W.
摘要:
A substrate transport container having a carrier box including a container body and a door hermetically sealably covering an opening provided in the front of the container body. Partitions form a circulating flow path in the carrier box. The circulating flow path has a flow path in which air flows toward substrates and a flow path in which air flows toward a fan. A substrate carrying section is disposed in the flow path in which air flows toward the substrates to carry the substrates in such a way that the principal surfaces of the substrates are approximately parallel to the flow path in which air flows toward the substrates. A particle removing filter and a gaseous impurity trapping filter are placed on the upstream side of the substrate carrying section in the flow path in which air flows toward the substrates. A fan motor for driving the fan is incorporated in the carrier box to form an air current for circulating through the circulating flow path.
