Patent number: 9132778Abstract: A movement mechanism of a luggage board for dividing a vehicle luggage compartment into upper and lower parts. Sidewalls on either side of the luggage compartment are each provided with a guide part for guiding guide protrusions when a luggage board moves between the upper and lower positions and a support part for supporting the luggage board. The guide part has a lower guide section inclined such that a vehicle rear side thereof is positioned above a vehicle front side thereof and an upper guide section extending toward the front of the vehicle from the end of the lower guide section on the vehicle rear side. The support part is provided on each sidewall of the luggage compartment more toward the rear of the vehicle than an intersection part between the lower guide section and the upper guide section on the vehicle rear side.Type: GrantFiled: February 14, 2013Date of Patent: September 15, 2015Assignees: Nissan Motor Co., Ltd., Kasai Kogyo Co., Ltd.Inventors: Shoichi Yoshizawa, Atsushi Akiba, Masatoshi Yamashita, Shigehiro Okada

Patent number: 8047571Abstract: A fixture structure for an in-vehicle electronic apparatus includes an in-vehicle electronic apparatus fixture bracket through which an in-vehicle electronic apparatus is attached to a vehicle body. The in-vehicle electronic apparatus fixture bracket includes a retreat structure part allowing the in-vehicle electronic apparatus to retreat toward the front of the vehicle body when a dynamic load is inputted into the in-vehicle electronic apparatus. The retreat structure part includes: a hinge part allowing a lower portion of the in-vehicle electronic apparatus fixture bracket to rotate together with the in-vehicle electronic apparatus, toward the front of the vehicle body about an upper portion of the in-vehicle electronic apparatus fixture bracket; and a rotational displacement accepting part allowing the lower portion of the in-vehicle electronic apparatus fixture bracket to be displaced due to its own rotation toward the front of the vehicle body.Type: GrantFiled: December 18, 2007Date of Patent: November 1, 2011Assignee: Calsonic Kansei CorporationInventors: Teruaki Takeda, Shoichi Yoshizawa, Kazumi Oosawa, Takeyoshi Katou

Patent number: 6863839Abstract: A composition for resin-bonded magnets. The resin-bonded magnets using the composition of the resin have excellent service lives in industry, excellent magnetic characteristics and excellent mechanical strength. A composition for resin-bonded magnets contains a magnetic powder and resin binder. The magnetic powder contains a transition metal element as one of the constituent elements. The binder contains, as the major ingredient, a thermosetting resin containing an organic peroxide and having radical-polymerization reactivity, and is further incorporated with an N-oxyl compound. Also disclosed is a composition including magnetic powder, thermosetting resin having radical-polymerization reactivity and organic oxide as the major ingredients, and a resin-bonded magnet using the same.Type: GrantFiled: July 12, 2002Date of Patent: March 8, 2005Assignee: Sumitomo Metal Mining Co., Ltd.Inventors: Shoichi Yoshizawa, Ryuji Kodama, Shin-ichi Hayashi
