Publication number: 20130061622Abstract: A refrigerating and air-conditioning apparatus is provided, with which a cold-storage/refrigeration load and air-conditioning loads such as a cooling load and a heating load can be simultaneously processed and a stable heat source can be supplied throughout the year. In the refrigerating and air-conditioning apparatus, heating energy or cooling energy stored in the primary-side refrigerant is usable as an air-conditioning load through the indoor heat exchanger while cooling energy stored in the primary-side refrigerant is transferred to the secondary-side refrigerant circulated in the cold-storage/refrigeration refrigeration cycle through the first refrigerant-refrigerant heat exchanger so as to be usable as a cold-storage/refrigeration load.Type: ApplicationFiled: June 18, 2010Publication date: March 14, 2013Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Tsuyoshi Kubota, Hirofumi Koge, Koji Azuma

Patent number: 8363076Abstract: A printing apparatus 1 compares a distance ? from a printing finish position of received printing data to a card rear end with a distance ? set corresponding to a peeling distance ? in which an ink ribbon R peels off from a card C, and thereby determines whether or not the printing finish position is within the distance ? from the card rear end. As a result, when it is determined that the printing finish position is within the distance ? from the card rear end, it is controlled that reeling of the ink ribbon R is performed by at least a distance obtained by adding the distance ? to the distance ? after printing on the card C is finished, and that the thermal head is then retreated to a retreat position. By this means, when the printing finish position is in the vicinity of the card rear end, the sag of the ink ribbon pulled out by a drop of the thermal head is resolved, and the ink ribbon does not wind itself around the platen roller.Type: GrantFiled: August 30, 2010Date of Patent: January 29, 2013Assignee: Nisca CorporationInventors: Yuichi Aihara, Tsuyoshi Kubota

Patent number: 8335377Abstract: Based on an input operation by an operator, a line drawing processor sets a designated region and sets identification points in the designated region to generate first and second identification data, each data representing a colored pixel cluster linked to each of the identification points. The line drawing processor further extracts at least one closed region that is not colored in the second identification data and makes a comparison in area between each closed region and the pixel cluster colored in the second identification data to determine whether the closed region requires coloring or not. For line drawing data, the line drawing processor then applies the same color to the pixel cluster identified in the second identification data and the closed region determined to require coloring.Type: GrantFiled: March 10, 2009Date of Patent: December 18, 2012Assignee: Dainippon Screen MFG Co., Ltd.Inventors: Itaru Furukawa, Tsuyoshi Kubota

Publication number: 20110187721Abstract: Multi-level gradation representation data D2 obtained by representing line drawing data D1 with a multi-level gradation is acquired, and cores are extracted from a line drawing. Further, a closed region surrounded by a core and smaller than a predetermined reference is selected. Then, the barycentric point of the selected closed region is determined, and a plurality of adjacent points adjacent to the barycentric point on the basis of a predetermined distance are defined. Thereafter, by reference to the multi-level gradation representation data D2, gradation values corresponding to the barycentric point and each of the adjacent points are acquired and compared with each other. Further, an adjacent point having the closest gradation value to the gradation value corresponding to the barycentric point is selected. Then, a boundary line lying between a closed region including the barycentric point and a closed region including the selected adjacent point is deleted.Type: ApplicationFiled: December 8, 2008Publication date: August 4, 2011Inventors: Itaru Furukawa, Tsuyoshi Kubota

Publication number: 20100328337Abstract: A plurality of closed regions constituting a line drawing image are extracted and displayed on a display means. A desired closed region included among the plurality of displayed closed regions is extracted as an image layer by specifying the desired closed region by means of a manipulation means. At this time, a closed region display screen for displaying the extracted closed regions thereon and an image layer display screen for displaying the extracted image layer thereon are displayed in side by side relation on the display means. Thus, whether an appropriate closed region is converted to the image layer or not is easily determined. Also, when a plurality of closed regions are specified, the plurality of specified closed regions are extracted as an image layer. Thus, the plurality of closed regions are treated together as the single image layer.Type: ApplicationFiled: November 25, 2008Publication date: December 30, 2010Inventors: Itaru Furukawa, Tsuyoshi Kubota, Tsutomu Kawaguti

Patent number: 7517576Abstract: The invention provides a vacuum insulation panel to which moisture and gas do not easily adsorb while it is being processed or being in storage in an unfinished state. The vacuum insulation panel includes a core provided with air circulation, a getter material which adsorbs moisture and gas from the core, an inner film bag which accommodates the core and the getter material, and an outer barrier bag which accommodates the inner film bag. The getter material is filled in an incision provided on the surface of the core. To prevent the getter material from getting out of the incision, the opening of the incision is narrowed by evacuating air from the interior of the inner film bag and, concurrently, compressing the inner film bag and the core.Type: GrantFiled: October 11, 2005Date of Patent: April 14, 2009Assignee: Hitachi Appliances, Inc.Inventors: Wataru Echigoya, Kuninari Araki, Tsuyoshi Kubota, Takashi Miseki
