  • Publication number: 20200117091
    Abstract: The pattern-forming method includes: applying a silicon-containing film-forming composition directly or indirectly on at least an upper face side of a substrate to form a silicon-containing film; applying a resist film-forming composition directly or indirectly on an upper face side of the silicon-containing film to form a resist film; exposing the resist film to an extreme ultraviolet ray or an electron beam; and developing the resist film exposed to form a resist pattern. The silicon-containing film-forming composition contains a compound having a first structural unit represented by formula (1), and a solvent. In the formula (1), R1 represents a substituted or unsubstituted divalent hydrocarbon group having 1 to 20 carbon atoms; and X and Y each independently represent a hydrogen atom, a hydroxy group, a halogen atom or a monovalent organic group having 1 to 20 carbon atoms.

  • Patent number: 10571827
    Abstract: A device that replenishes developer to a developer unit and includes a storage for storing developer, an agitation member, and a vibration plate. The agitation member has a blade shape and is rotationally driven to agitate the developer in the storage. The vibration plate extends from a top portion towards a bottom portion of the storage along a rotation direction of the agitation member, and includes a vibration portion that vibrates due to contact with the agitation member undergoing rotation. A top end of the vibration plate is fixed and a bottom end of the vibration plate is a free end, and there is a gap between the vibration portion and an inner wall of the storage. The vibration plate is provided with an engagement protrusion towards the free end that engages with the agitation member and causes the agitation member undergoing rotation to deform then spring back.

  • Patent number: 10137569
    Abstract: A multi-articulated manipulator is operated without rickety movement by a pair of grasping members, springs for the grasping members, and other springs extended across the foremost outer shell and the basement outer shell. The manipulator is small in size, easy to handle, reliable, better response and high precision in medical applications. With the multi-articulated manipulator, the foremost outer shell is connected to the basement outer shell in a bending manner. A pair of grasping members of claw members is connected to the foremost end of the foremost outer shell. The claw members are operated with a pair of claw power-transmission shafts and energized with springs to be biased towards their closed situation. The foremost outer shell and the basement outer shell are operated with claw power-transmitting shaft and normally biased by springs towards their closed situation.

  • Patent number: 9494219
    Abstract: Tables having nuts are easily assembled and/or replaced on a lead screw from an open side thereof. The lead screw has a large screw near a motor and a small screw remote from the motor. A right-handed screw mating with one of the nuts and a left-handed screw mating with the other of the nuts lie adjacent to each other in the lengthwise direction. A stepped portion of flange coming into an inner ring of a bearing is placed on an end shaft in adjacency to the large screw. The pair of the tables after energization of the motor is controlled to come to a preselected phase in which the tables get closer or nearer each other or come to another preselected phase in which the tables go away from each other.
