Publication number: 20080047636Abstract: Method of manufacturing a metal gasket including a base plate having at least fluid passage holes and circular beads surrounding the fluid passage holes, the base plate being formed by providing a rubber coating layer on a surface of a metal plate with a base coat and an adhesive interposed therebetween. A metal plate having low-temperature age-hardening characteristics is used as the metal plate of the base plate. After the base coat is applied to the metal plate and dried at a temperature lower than a low aging temperature of the metal plate, press-working of the circular beads is performed on the metal plate. Thereafter, the metal plate is age-hardened while burning the base coat at the low aging temperature of the metal plate. A metal gasket having excellent durability and circular beads which are hardly broken even when crushed, is obtained.Type: ApplicationFiled: August 23, 2005Publication date: February 28, 2008Inventors: Hiromitsu Sasaki, Norifumi Misumi, Takashi Yajima, Masabumi Miyashita, Takashi Katsurai, Tadao Nishiyama, Yasunori Murakami

Patent number: 7249450Abstract: A lawn mower comprises a power source for rotatably driving an output shaft, a housing having an interior space having a generally spiral-shaped portion, and a cutting blade disposed in the interior space of the housing and connected to the output shaft for rotation therewith to cut grass. The rotating cutting blade coacts with the spiral-shaped portion of the interior space to generate a swirling air flow that causes the cut grass to swirl within the interior space. A grass discharge passage communicates with the interior space of the housing and discharges therethrough grass cut by the cutting blade and swirling within the interior space of the housing. A pivotal shutter is pivoted about a generally vertical axis by manual operation of a control member to open and close the grass discharge passage. The pivotal shutter comprises a pivotal shaft and a unitary shutter member mounted on the pivotal shaft to undergo pivotal movement therewith for opening and closing the grass discharge passage.Type: GrantFiled: November 29, 2004Date of Patent: July 31, 2007Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Tetsuo Iida, Takao Kobayashi, Hiromitsu Sasaki, Kenzo Shimada, Masanori Shin
