Patent number: 5216887Abstract: A radiative-type air-conditioning unit capable of being freely moved to and set in different positions, and used to deal with the problems concerning the unevenly distributed heat loads in a closed office in which a plurality of office automation (OA) machines are installed. This radiation air-conditioner consists of a radiation endothermic/radiating plate including a radiation generating surface (21) formed on one side surface of a panel (20), a plurality of thermoelectric elements (22) attached to the other side surface of the panel (20), and a plurality of heat exchanger means (25) attached to the other surfaces of these thermoelectric elements (22). Accordingly, noise does not occur in this radiation air-conditioner, and maintenance work therefor is substantially not required. Since this radiation air-conditioner can be installed in a small space owing to its small weight and thickness and compact structure, it is used very extensively.Type: GrantFiled: December 23, 1991Date of Patent: June 8, 1993Assignees: Kabushiki Kaisha Komatsu Seisakusho, Kajima Corp.Inventors: Kan-ichi Kadotani, Tetsuo Onishi

Patent number: 4605926Abstract: An illegal-sheet-material detecting apparatus, which is adapted to detect whether the property of each of the passing sheet materials is legal or not in a sheet manufacturing machine, provided with a comparison circuit for detecting the lag of the same detection value of the n th+ first sheet material with respect to the detection value showing the property such as thickness, size or the like of the optional portion of the n th sheet material memorized in the memory circuit as an electric signal. When the lag detected by the comparison circuit has exceeded a predetermined range, the counting operation of the sheet material is caused to stop thereby to use the detection value of the n th sheet material as a reference value for comparing it with the n th+ first sheet detection value.Type: GrantFiled: September 13, 1982Date of Patent: August 12, 1986Assignees: Duplo Seiko Corp., Duplo Manufacturing Corp.Inventors: Tetsuo Onishi, Yoshihide Sugiyama
