  • Publication number: 20250166078
    Abstract: A selection system selects an operational condition of equipment in which a cost including a variable expense of the equipment is low. The selection system includes an input part, a first arithmetic part, a second arithmetic part, and a selecting part. The input part is usable to input a restriction relating to an operation of the equipment, a spec of a product to be produced with the equipment, and a production quantity of the product. The first arithmetic part automatically executes a simulation of the operation of the equipment, and calculates a candidate of the operational condition satisfying the restriction, the spec, and the production quantity. The second arithmetic part calculates the variable expense when operating in accordance with the candidate. The selecting part causes the first and second arithmetic parts to repeat the calculations, and automatically compares variable expenses to select a first operational condition.

  • Patent number: 9951882
    Abstract: Provided is a cap for a handwheel that opens and closes a valve, capable of being readily attached to the handwheel without requiring a large space around the handwheel. The cap has easily switchable two working modes: One is a co-rotation mode where the cap is capable of rotating with the handwheel and the other is an independent rotation mode where the cap is capable of rotating independently of the handwheel. The cap has an internal casing to be securely fitted to the handwheel; an external casing being rotatable around its axis and having the internal casing in an interior thereof; a clutch for connecting the external casing with the internal casing and for disconnecting the former from the latter; and a maintaining member for keeping the external casing rotatable independently of the internal casing when they are disconnected by the clutch.
