  • Patent number: 10668656
    Abstract: In a molding die, movable die elements are respectively received in die element receiving holes formed in a frame plate. An end surface of the frame plate, which faces a cavity at a location that is other than locations of the die element receiving holes, forms a frame portion compression surface. An end surface of each movable die element, which faces the cavity, forms a split compression surface. Die element drive devices respectively drive the split compression surfaces of the movable die elements. A whole compression plate commonly supports an opposite end part of the frame plate and opposite end parts of the movable die elements, which are opposite from the cavity. When the whole compression plate is moved forward, the whole compression plate integrally drives the frame plate and the movable die elements forward. A whole drive device drives the whole compression plate.

  • Publication number: 20200078997
    Abstract: In an injection process, molten resin is successively injected from a first flow channel and a second flow channel connected with each other in order into a cavity of a metal mold. High-temperature resin existing in the first flow channel is injected in advance into the cavity as a part of a single shot of molten resin to later form a skin layer of a molded article. other low temperature resin near a flowable limit existing in the second flow channel is subsequently injected into the cavity as another part of the single shot of molten resin to later form a core layer of the molded article. A low temperature resin remaining in the first flow channel when injection is completed is warmed to be a high-temperature resin before the next cycle, thereby allowing successive molding of molded articles.

  • Publication number: 20200081781
    Abstract: A first node group including at least three nodes is predefined in a distributed storage system. Each node of the first node group is configured to send data blocks stored in storage devices managed by the node to other nodes belonging to the first node group. A first node is configured to receive data blocks from two or more other nodes in the first node group. The first node is configured to create a redundant code using a combination of data blocks received from the two or more other nodes and store the created redundant code to a storage device different from storage devices holding the data blocks used to create the redundant code. Combinations of data blocks used to create at least two redundant codes in redundant codes created by the first node are different in combination of logical addresses of constituent data blocks.

  • Patent number: 10503424
    Abstract: A storage system is provided that has a plurality of flash packages and a storage controller that controls read/write processing between a host and the flash packages. When data identical to data written in a second address of a second flash package of the plurality of flash packages is written to a first address of a first flash package of the plurality of flash packages, the storage system may store the second address in the first package in association with the first address, and perform deduplication. When the first flash package stores the second address in association with the first address and a read request for the first address is received from the storage controller, the first flash package may return the second address to the storage controller. In response to receiving the second address, the storage controller may acquire target read data from the second flash package.

  • Patent number: 10444992
    Abstract: A storage device provides a logical space based on a storage medium that is configured by a plurality of logical areas to the higher-level apparatus, and a base data range exists in the storage medium for each logical area. The storage device reads the base data from the base data range that is corresponded to a write destination logical area to which the write destination logical address belongs, and creates difference data that is an exclusive OR of first data that is the base data and second data that is any one of data based on write data and the write data. The storage device creates compressed difference data by compressing the difference data, writes the compressed difference data to the storage medium, and associates a difference data range that is a range in which the compressed difference data has been written with the write destination logical area.
