Patent number: 8162360Abstract: A handle knob to conduct an opening/closing operation of a front door is provided on an outer-face side of an outer panel, and a handle base to pivotally support the handle knob is provided on an inner-face side of the outer panel. A beltline reinforcement to reinforce an beltline portion of the outer panel is provided on the inner-face side of the outer panel. The handle base is connected to the beltline reinforcement via an connecting portion. Thereby, the support rigidity of the handle base can be increased, thereby properly preventing the handle base from moving by an improper access.Type: GrantFiled: January 14, 2008Date of Patent: April 24, 2012Assignee: Mazda Motor CorporationInventors: Hirotaka Takaya, Kohji Takada, Toyohiko Kobayashi, Noboru Shono

Patent number: 5959161Abstract: To offer a method of producing useful para-menthane-3,8-diol having the excellent repellent action to harmful living things, including noxious insects, in high purity and high yield, simply, and economically by the use of citronellal as a raw material compound.The above-mentioned problems are resolved by the production method of this invention wherein citronellal is treated with aqueous sulfuric acid solution of 0.02 to 1.0 wt. % in concentration to produce para-menthane-3,8-diol. In case of recovering the produced para-menthane-3,8-diol, a method is preferably adopted, wherein after the reaction product is extracted with an aliphatic hydrocarbon solvent of 5 to 8 in carbon number, the extract is cooled down at temperature higher than the melting point of said aliphatic hydrocarbon solvent and of -10.degree. C. or less to crystallize para-menthane-3,8-diol.Type: GrantFiled: October 27, 1998Date of Patent: September 28, 1999Assignee: Takasago International CorporationInventors: Hiroyuki Kenmochi, Teruyoshi Akiyama, Yoshifumi Yuasa, Toyohiko Kobayashi, Akio Tachikawa
