摘要： A stator 13 on whose outer circumference a plurality of magnetic poles 13a are arranged is mounted on a substrate 11, and a rotor 14 is rotatably disposed around the stator. The inner circumferential face of the rotor is provided with a magnet 15 magnetized to have alternately opposite polarities in a direction opposing the stator, and magnetized to have alternately opposite polarities in a direction opposing the substrate. The outer circumferential ends of the magnetic poles of the stator are provided with a first extended portion 13c that extends from a magnetic pole base 13d to the substrate side, and a second extended portion 13b that extends from the magnetic pole base to a side opposite the substrate side.

摘要： A process for easily and industrially advantageously producing a high-purity 2-aralkyl-3-acetylthiopropionic acid and a high-purity 2-aralkylpropionic acid having a leaving group in the 3-position from easily available compounds. A 2-aralkyl-1-propanol having a sulfonyloxy group or halogen atom in the 3-position is oxidized with a permanganate under acidic conditions to produce a high-purity 2-aralkylporpionic acid having sulfonyloxy or the halogen in the 3-position. This acid is reacted with a thioacetate in the presence of water to produce a high-purity 2-aralkyl-3-acetylthiopropionic acid.

摘要： An ejector pin with a pressure sensor is provided, of which the sensor output can be utilized without any correction even in different diameter thereof, so that no design changes are required according to loads to the ejector pin. The ejector pin has a bar portion for extruding a molded component and a sleeve portion slidably housing the bar portion. The end of the bar portion faces the cavity from the opening at the end of the guide portion. A housing room is defined by the step portion at the lower end of the sleeve portion. A strain producing portion with an U-shaped cross section fixed on the base end of the bar portion is disposed inside the housing room. A strain sensor is attached on the lower surface of the beam of the strain producing portion. Only the area of the end of the bar portion is related to the pressure detection. When the pressure of a resin is applied on the end of the bar portion, the downward load on the bar portion bends the beam down. The strain sensor outputs a signal corresponding to the load and the pressure is worked out. By separately preparing plural kinds of sleeve portions with different outer diameters, the thickness of an ejector pin can be arbitrarily set according to conditions.
