  • Publication number: 20210388907
    Abstract: [Object] To provide a gate valve in which a valve plate can be detached from a valve rod easily and reliably even if the valve rod is tightly inserted in a valve-plate mounting hole. [Solution] In a gate valve in which a valve plate 3 and a valve rod 4 are detachably connected along a rod axis L by screwing a connecting screw 14 in a screw hole 21 formed at an end of a valve rod 4 along the rod axis L through a screw insertion hole 18 formed in a valve plate 3, the valve plate 3 includes a contact portion 25 that is in contact with the connecting screw 14, and when the connecting screw 14 is loosened to detach the valve plate 3 from the valve rod 4, the valve plate 3 is displaced along the rod axis L together with the connecting screw 14 by an impellent force of the connecting screw 14 via the contact portion 25 to move to a valve-plate detaching position at which the connecting screw 14 comes out of the screw hole 21 of the valve rod 4 completely.

  • Patent number: 11200172
    Abstract: A storage system includes a plurality of controllers and a plurality of storage drives. A first cache area and a second cache area are set in a memory. The first cache area is permitted to be written data by the plurality of storage drives, and the second cache area is not permitted to be written data by the plurality of storage drives. In a case where the plurality of controllers duplicates data stored in the cache area to a cache area of another controller for redundancy, the plurality of controllers causes the data to be redundant in a second cache area of the other controller in a case where the data is stored in the first cache area, and causes the data to be redundant in a first cache area of the other controller in a case where the data is stored in the second cache area.

  • Patent number: 11174950
    Abstract: A spacer having a wedge-shaped flat plate portion and an engagement protrusion is interposed between a hole end surface of mounting hole of a valve plate and a rod end surface of mounting portion of a valve rod, which thereby forms a wedge-shaped gap between the spacer and the hole end surface so as to open frontward. A fastening force of a valve-plate fixation screw generates a moment M that deforms the valve plate in a direction of narrowing the gap. At the same time, the engagement protrusion of the spacer is pressed into a wedge-shaped space between the inclined surface portion of the rod end surface and the rear hole-wall surface of the mounting hole, which causes the front hole-wall surface of mounting hole of the valve plate to press the rod front surface of mounting portion of the valve rod.

  • Publication number: 20210305111
    Abstract: In a semiconductor device, on a heat dissipation portion of a lead frame opposite to a mounting portion on which a semiconductor element is mounted, a thin molding portion having a thickness of about 0.02 mm to 0.3 mm is formed by a second molding resin which is a high-heat-dissipation resin. A scale-like portion on which scale-shaped projections are consecutively formed is provided over both sides across a resin boundary portion of the heat dissipation portion. The scale-like portion reaches abutting surfaces of an upper die and a lower die of a mold used in a molding process. Thus, the same void inhibition effect as with an air vent is obtained.

  • Publication number: 20210125891
    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.
