  • Patent number: 11276205
    Abstract: An image processing apparatus performs, in a case where an image targeted for processing is rotated, predetermined compression processing on a predetermined block targeted for processing by referring to a block which differs according to a rotational angle. Then, the image processing apparatus performs predetermined decompression processing on compressed data corresponding to the predetermined block by referring to a block referred to in the predetermined compression processing performed on the predetermined block.

  • Patent number: 8945445
    Abstract: Provided is a method of producing an anode material for a non-aqueous electrolyte secondary battery having battery characteristics equivalent to those of a conventional product by simpler production steps than those of a conventional method. A thermally-polymerized petroleum based or coal based pitch is cooled to the softening point or below so that the pitch is solidified to obtain a solidified pitch. The solidified pitch is ground to form a fine pitch powder having an average particle size (median size) of 60 ?m or smaller. Then, the fine pitch powder is compression molded at a pressure of 20 to 100 MPa or 0.1 to 6 MN/m to form a porous compression molded pitch. The porous compression molded pitch is subjected to infusibilization treatment.

  • Publication number: 20140305115
    Abstract: A cushion valve device includes a valve block that includes first, second and first discharge passages. The first passage is disposed between a first supply/discharge passage of an operating valve and a first pilot passage of a switching valve, and includes a first throttle. The second passage is between a second supply/discharge passage of the operating valve and a second pilot passage of the switching valve. The first discharge passage connects to the first passage and a tank. A first check valve is provided on the first discharge passage. The first check valve includes: a poppet valve element configured to be seated on a valve seat portion, thereby closing the first discharge passage; and a piston configured to move the poppet valve element when the pressure of pilot oil in the second supply/discharge passage has become higher than or equal to a predetermined pressure, thereby opening the first discharge passage.

  • Patent number: 8470206
    Abstract: There are provided a method of producing an anode material for a non-aqueous electrolyte secondary battery which is suitable for use in a high input/output current-type non-aqueous electrolyte secondary battery exemplified by a non-aqueous electrolyte secondary battery for a hybrid electric vehicle (HEV), has reduced irreversible capacity and superior charge-discharge efficiency, and an anode material obtained by the above production method. A method of producing an anode material for a non-aqueous electrolyte secondary battery from a petroleum-based pitch material, comprising a tar removal step in which an infusibilized pitch having an oxygen content of 5 to 20 wt % is heated to a temperature of 480° C. to 700° C. while flowing an inert gas at the space velocity of 0 to 120 (min?1).

  • Patent number: 5375061
    Abstract: A production management method in a production system for semiconductor devices uses processing progress information for each of the plural number of manufacturing apparatus as the basis for performing start allocation of a plural number of next start product groups. When the state of progress has reached a certain stage and is close to the end, a product group of the same type as that which a manufacturing apparatus is processing from amongst start standby product groups is determined as the object of same type priority allocation. A link is made beforehand between that product group and a manufacturing apparatus for which that processing is about to end, and a product group that is an object of same type priority allocation to a manufacturing apparatus that is processing products of that same type, is not started by a manufacturing apparatus that is processing a product of a different type even if that manufacturing apparatus finishes its processing of a product of that different type earlier.
