Publication number: 20140037894Abstract: Provided is a composition for a lightweight heat-insulating material having high heat-insulating properties. The composition for a heat-insulating material contains a fibrous material, inorganic foamed particles, a thermosetting resin, and a foaming agent. Since the composition for a heat-insulating material contains the inorganic foamed particles and the foaming agent in addition to the fibrous material and the thermosetting resin, the weight can be reduced and the thermal conductivity can be lowered due to the inorganic foamed particles having low specific gravity. Further, the thermosetting resin is caused to foam by the foaming agent, and the weight can be reduced and the thermal conductivity can be lowered. A lightweight heat-insulating material having high-insulating properties can be obtained.Type: ApplicationFiled: February 23, 2012Publication date: February 6, 2014Applicants: MITSUBISHI HEAVY INDUSTRIES, LTD., LIGNYTE CO., LTD.Inventors: Hisato Higuchi, Shinsuke Takeda, Nagaharu Hara, Tetsuro Ise, Junko Watanabe, Aiichiro Tsukahara, Masayuki Yamashita, Fumihito Takeda

Patent number: 5923013Abstract: A print control system managing a print job on a job basis and on a page basis. When a print job is interpreted, a job description file and page data for each page are created. The job description file contains the attribute of the entire job and a job element (content) list. An item of page data is associated with the print attribute of each page including image data. The job control module extracts necessary image data according to the job element list and sends it to a printer.
