Patent number: 9648893Abstract: Disclosed is an aerated fat-based confectionery that, unlike a conventional shell-type or tapered shape, has a novel shape, that is, a cubic or rectangular parallelepiped shape having top, bottom, and side surfaces in contact with and perpendicularly to each other, or any shape such as an animal or flower shape having a given thickness, has a light texture and a sharp melt-in-the-mouth sensation, does not require alignment in packaging. The confectionery can be obtained by aerating a fat-based confectionery mass having a fat content of 30 to 60% by weight such as chocolate to a specific gravity of 0.5 to 1.0 and cutting the aerated mass with a heated wire so that the side surface is perpendicularly to the top and bottom surfaces.Type: GrantFiled: September 15, 2011Date of Patent: May 16, 2017Assignee: MEIJI CO., LTD.Inventors: Hiroyuki Utsunomiya, Masamitsu Tanaka, Yuka Nagashima, Takanori Chiwata

Patent number: 8056671Abstract: An exhaust-gas purification device disposition structure of a vehicle, comprises a fuel tank with a fuel supply port which is disposed so as to be open to an outside of a vehicle compartment, and a urea tank to accommodate urea water solution as deoxidizer to purify exhaust gas. The urea tank is disposed outside the vehicle compartment, and a pouring port of the urea tank is provided inside the vehicle compartment. Accordingly, the urea water solution can be surely prevented from entering into the vehicle compartment even in case of the breakage of the urea tank, and the mistake of supplying the wrong liquid into the wrong supply (pouring) port tank which may be made by confusing the ports can be avoided.Type: GrantFiled: October 8, 2008Date of Patent: November 15, 2011Assignee: Mazda Motor CorporationInventors: Makoto Ikegami, Yukiichirou Shimada, Noritaka Sakiyama, Noriyoshi Sahashi, Kota Matsue, Chikara Ishihara, Shinya Matsumoto, Yoshikazu Nishimura, Yoshiaki Murakami, Masamitsu Tanaka, Ken Ueki

Orthoalkylation catalyst for phenol and process for producing orthoalkylated phenol with use thereof
Patent number: 6951966Abstract: The orthoalkylation catalyst for phenols of the invention is one produced by calcining a catalyst precursor comprising basic magnesium carbonate (a) and magnesium oxide (b) optionally together with manganese oxalate (c), the basic magnesium carbonate (a) and magnesium oxide (b) being mixed together at a weight ratio ((a)/(b)) of 20/80 to 80/20. The process for producing an orthoalkylated phenol according to the invention comprises performing a vapor phase reaction of a phenol with an alkyl alcohol in the presence of the above orthoalkylation catalyst so that an orthoalkylated phenol is obtained. The invention enables obtaining an orthoalkylation catalyst for phenols which has high activity and high selectivity, has long catalytic life and exhibits more stable catalytic life than those of conventional orthoalkylation catalysts for phenols.Type: GrantFiled: September 28, 1999Date of Patent: October 4, 2005Assignee: Honshu Chemical Industry Co., Ltd.Inventors: Mitsuhiro Higashi, Masamitsu Tanaka, Kenji Ekawa -
Patent number: 6615685Abstract: To avoid a steering shaft changing its orientation during a frontal collision, an automotive pedal support structure equipped with an operating pedal is disposed behind a dash panel of an automotive vehicle and the steering shaft comprising a universal joint disposed in the proximity of the operating pedal. Provided are a first bracket including first and second side wall portions, a connecting portion and a second bracket pivoted to the first bracket so as to be rotated during the frontal collision. The operating pedal is pivoted to the second bracket. During the frontal collision, the universal joint is longitudinally moved relative with respect to the first bracket while contacting with side surfaces of the first and second side wall portions.Type: GrantFiled: August 10, 2001Date of Patent: September 9, 2003Assignee: Mazda Motor CorporationInventors: Keisuke Miyoshi, Hiroyuki Utsumi, Masamitsu Tanaka

Patent number: 4789114Abstract: A composite tape guide for a cassette tape for a video tape recorder includes a cylindrical tape guide body formed of inexpensive material such as plastic. More than half of the circumferential surface of the tape guide body which contacts a video tape is covered with a sheet member of nonmagnetic material. This material has improved wear resistance and anti-corrosive properties, and exhibits less frictional resistance against the tape than the remainder of the guide body surface. Thus, the guide exterior surface forms a composite of layer of two different materials.Type: GrantFiled: August 14, 1987Date of Patent: December 6, 1988Assignee: Sanwa Needle Bearing Co., Ltd.Inventor: Masamitsu Tanaka
