Patent number: 11241873Abstract: For forming a sound absorption/insulation honeycomb panel by stacking an air-permeable material, a honeycomb material filled with a sound absorption material and a reflector, and adhesively joining these materials, it is hard to join the honeycomb material and the air-permeable material adhesively due to a thin wall surface of the honeycomb material and a resultant line to surface adhesive joint therebetween, causing a problem of low adhesive strength. By using a water absorption honeycomb material, an adhesive joint is formed with an adhesive joint area increased by dipping an end of a wall surface of a cell forming the water absorption honeycomb material into a water-soluble adhesive, making the end flexible over a fixed period of time, and then pressing the end strongly against an air-permeable material as a counterpart of the adhesive joint to deform a tip into an inverted T-shape.Type: GrantFiled: June 26, 2019Date of Patent: February 8, 2022Assignee: SHIZUKA CO., LTD.Inventors: Koichi Take, Tomohisa Nakamura, Daisuke Iwasaki, Takuma Nemoto

Patent number: 8215624Abstract: A jig pallet for conveying a workpiece that is placed on it and has a portion to be worked. The jig pallet has a conveyance carriage (A) movable along a production line, a workpiece receiving member (B) provided on the conveyance carriage (A) and on which the workpiece is placed, a pressing mechanism (E) to be placed so as to face a peripheral section of a to-be-worked portion of the workpiece placed on the workpiece receiving member (B), and an opening/closing member (D) on which the pressing mechanism (E) is provided. When the opening/closing member (D) is closed, the pressing mechanism (E) presses a peripheral section of the to-be-worked portion of the workpiece from above, and when being opened, the pressing is released, enabling the opening/closing member (D) to be opened and closed, with one end of the conveyance carriage (A) functioning as the support point, and allowing the workpiece to be taken out.Type: GrantFiled: April 13, 2007Date of Patent: July 10, 2012Assignee: Sintokogio, Ltd.Inventors: Masanori Tomioka, Tomohisa Nakamura, Susumu Fujita

Patent number: 8215004Abstract: A fabrication line that utilizes a jig pallet that is commonly used in processing equipment to efficiently finish and assemble semifinished products of plural shapes. The jig pallet includes a holding member D for holding a semifinished product W and an opening/closing device G1 for opening and closing the holding member D, and allows the semifinished product W to be mounted and dismounted by opening and closing the holding member D with the opening/closing device G1. The jig pallet is transported to processing equipment M1, M2, and M3 to allow the semifinished product to be processed in the fabrication line. An opening/closing driving device G2 that engages the opening/closing device G1 to open and close the holding member is provided along the fabrication line.Type: GrantFiled: February 27, 2008Date of Patent: July 10, 2012Assignee: Sintokogio, Ltd.Inventors: Masanori Tomioka, Tomohisa Nakamura, Susumu Fujita, Takanobu Tozaki

Patent number: 7480141Abstract: An electronic equipment of the present invention includes housings and, a substrate, electronic components mounted on the substrate, a heatsink which is connected to the electronic component, connection means for connecting the heatsink to the housing depending on a temperature in the housing and for forming a heat conduction path from the electronic component to the housing, and a fan for flowing cooling air into the housing. The substrate, the electronic component, the heatsink, the connection means, and the fan are arranged in the housing. Depending on the temperature, the connection means promotes heat transfer from the heatsink to the housing, which has a large radiation area, in addition to a cooling (radiation) operation using the fan. As a result, the cooling of the electronic component inside the housing is promoted during operation.Type: GrantFiled: August 13, 2007Date of Patent: January 20, 2009Assignee: International Business Machines CorporationInventors: Hiroyuki Takenoshita, Hideki Sasaki, Tomohisa Nakamura, Seiji Koyama
