摘要： A press-fitting direction position of a pressing surface of a pressing portion of a press-fitting tool and a press-fitting direction position of a restriction surface of a restriction portion of the press-fitting tool are set so that one of a press-fitting component and a press-fitting target component is stopped at a prescribed press-fitting stop position. A press-fitting method includes: adjusting a press-fitting interval dimension in a press-fitting direction between the pressing surface of the pressing portion and the restriction surface of the restriction portion so as to obtain a press-fitting stop position that is set according to component dimensions of the press-fitting component and component dimensions of the press-fitting target component; press-fitting the press-fitting component with the press-fitting target component; and stopping the press-fitting of the press-fitting component with the press-fitting target component by bringing the restriction portion into contact with the press-fitting target component.

摘要： A control device includes first and second input terminals to which a DC voltage for driving a motor is input, and a control unit. The control unit sets a rotation direction of the motor based on first input to the first input terminal or the second input terminal. A rotation speed of the motor is changed based on a subsequence input of the DC voltage.

摘要： In a system, a server establishes a session for verification of drawing information and implements information communication between clients connected to the session. The verification in the session is performed by laying out rendering object information used to render an object of the drawing information in a virtual 3D space based on layout information. The system comprises: establishing, upon receiving a session start request from one of the clients storing a verification target drawing information, the session to which the client storing the drawing information is able to connect; managing state information indicating a state of the 3D space for the session; receiving information of a verification input made at the clients; changing the state information upon receiving the verification input; and transmitting, to the connected clients, shared information necessary to render the 3D space.

摘要： A manufacturing system manufactures a rotating assembly by attaching a plurality of attached target members in a circumferential direction of a rotating main body portion. A storage member capable of storing the plurality of attached target members is placed on a stand. A measurement device measures a physical amount of the attached target member An attachment device attaches one attached target member to a predetermined position in the circumferential direction of the rotating main body portion based on the physical amount measured by the measurement device A transfer device transfers the attached target member.

摘要： A vertical moving method of a vertical moving unit on which a conveyance target object is mounted includes steps of causing a non-electric biasing unit to generate a biasing force to raise the vertical moving unit, causing an electric motor unit to generate a thrust in a direction to raise the vertical moving unit or a thrust in a direction to lower the vertical moving unit, and causing an electromagnetic brake unit to generate a braking force to resist a movement of the vertical moving unit. Independently of presence/absence of the object and a weight of the object, the thrust and/or the braking force is controlled such that the vertical moving unit stops when an external force of overload more than a predetermined value acts on the vertical moving unit during a vertical movement.
