  • Patent number: 11555546
    Abstract: In a connection mechanism that connects a valve shaft to air cylinders, shake prevention mechanisms are disposed at facing portions at which outer side surfaces of side frames face inner side surfaces of housings of the air cylinders and/or facing portions at which inner side surfaces and of the side frames face left-hand and right-hand side surfaces of a center frame. The shake prevention mechanisms include a sliding member that is disposed on a sliding surface that is formed on one of two surfaces that face each other and on the other and a spring mechanism that presses the sliding member in a direction in which the sliding member comes into contact with the sliding surface.

  • Patent number: 11543972
    Abstract: The present disclosure is to optimize processes in a storage system. A storage system includes: a first controller including a first computing device and a first memory; a second controller including a second computing device and a second memory; and an interface circuit that transfers data between the first controller and the second controller. The interface circuit reads first compressed data from the second memory. The interface circuit decompresses the first compressed data to generate first uncompressed data, and writes the first uncompressed data into the first memory.

  • Patent number: 11476224
    Abstract: In a wiring member, an element connection portion, a plate connection portion, and an upper surface portion are at height positions different from one another. The element connection portion has a through hole, and the plate connection portion has a through hole and a chamfer. The upper surface portion which is not connected to another portion, has projections asymmetrically disposed on both side surfaces thereof. Owing to these features, the type, the orientation, and the front and the back of the wiring member can be easily distinguished. Accordingly, it is possible to prevent incorrect assembling of the wiring member in a semiconductor module.

  • Patent number: 11402024
    Abstract: A gate valve includes a valve plate and a valve rod that are detachably connected along a rod axis by screwing a connecting screw in a screw hole formed at an end of a valve rod through a screw insertion hole formed in the valve plate. The valve plate includes a contact portion that is in contact with the connecting screw. When the connecting screw is loosened to detach the valve plate from the valve rod, the valve plate is displaced along the rod axis together with the connecting screw via the contact portion to move to a valve-plate detaching position at which the connecting screw comes completely out of the screw hole of the valve rod. Accordingly, the valve plate can be detached from the valve rod easily and reliably even if the valve rod is tightly inserted in the valve plate mounting hole.

  • Patent number: 11302597
    Abstract: A semiconductor device is provided with a heat dissipating face side skirt portion, which is a frame-form projection, on a heat dissipating face of a lead frame. Because of this, creepage distance increases with a small increase in an amount of resin, and insulating properties improve. Also, the heat dissipating face side skirt portion is molded via two transfer molding steps, wettability of the second molding resin with respect to a first molding resin and the lead frame increases, and adhesion improves. Furthermore, an end face of an inner lead is exposed in an element sealing portion on a mounting face side, and covered with a second thin molded portion molded using the second molding resin, whereby heat generated in a semiconductor element can efficiently be caused to escape from faces of both a first thin molded portion and the second thin molded portion, because of which heat dissipation improves.
