Abstract: An electromagnetic actuator includes: a stator; and a movable element attracted from a stroke start position to a stroke end position in a predetermined stroke in an axial direction by magnetic force generated between the stator and the movable element when a coil is energized. The stator includes a first stator located adjacent to the movable element at the stroke start position and a second stator located closer to the movable element at the stroke end position than at the stroke start position. The movable element includes a tapered portion so as to reduce a gap between the first stator and the movable element as the movable element is moved toward the stroke end position. The first stator includes a curved surface that has a convex shape so as to expand a gap between an opening end of the first stator facing the second stator and the movable element.

Abstract: A mover is attracted and is moved in an axial direction with a predetermined stroke by a magnetic force generated between a stator and the mover when a coil is energized. The stator includes: a first stator positioned at a side where a stroke start position of the mover is located, and a second stator positioned at another side where a stroke end position of the mover is located. The mover includes a tapered portion which has a diameter progressively reduced toward the second stator, and a small-diameter cylindrical portion which is shaped in a straight form and has a constant outer diameter along an entire axial extent of the small-diameter cylindrical portion. An outer wall of the small diameter cylindrical portion has the outer diameter that is equal to an outer diameter of a smallest-diameter part of the tapered portion.

Abstract: An electromagnetic actuator includes a stator and a movable element. The movable element is attracted from a stroke start position to a stroke end position in a predetermined stroke in an axial direction by magnetic force generated between the stator and the movable element when a coil is energized. The stator includes a first stator located adjacent to the movable element at the stroke start position and a second stator located closer to the movable element at the stroke end position than at the stroke start position. The movable element includes a tapered portion that has a diameter becoming smaller toward the second stator and a protrusion that protrudes from an end surface of the movable element close to the second stator.

Abstract: Disclosed is a transglutaminase having excellent stability. Also disclosed is a process for producing the transglutaminase. Specifically disclosed is a stabilized transglutaminase, which has such a structure in which a pro-sequence peptide of transglutaminase is bound to a mature transglutaminase. Also specifically disclosed is a process for producing stabilized transglutaminase, which includes the steps of culturing a microorganism capable of producing transglutaminase under the conditions where transglutaminase can be produced; and separating and collecting matured transglutaminase having a pro-sequence peptide bound thereto from a culture medium.

Abstract: An upper casing receives a rotor, which is rotated by a drive force of a motor. The upper casing includes a pump chamber, which receives the rotor, a planar surface portion, which is formed around an opening of the pump chamber, and a through hole. A lower casing includes a planar surface portion, which is formed around the opening of the pump chamber, and a through hole. The lower casing closes the opening of the pump chamber to form the pump chamber in cooperation with the upper casing. A resilient sheet is placed between the lower casing and a mount portion of the motor and includes a through hole. A screw is received through the through holes of the upper casing, the lower casing and the resilient sheet to securely connect the upper casing, the lower casing and the resilient sheet to the mount portion. A lower casing side surface of the resilient sheet includes a plurality of primary protrusions.
