Patent number: 5948554Abstract: The ZnO amount contained in the ferrite is lowered more than those of conventional ones to increase the mean coefficient of thermal expansion of the ferrite. Thus, a difference between the mean coefficient of thermal expansion of the ferrite and the mean coefficient of thermal expansion of the soft magnetic material is reduced. Further, the Fe.sub.2 O.sub.3 amount contained in the ferrite is suitably controlled to reduce the absolute value of the magnetocrystalline anisotropic energy K1 and the absolute value of the saturation magnetostriction .lambda.S. Thus, the absolute value of the apparent magnetic anisotropic energy is lowered, and the magnetic anisotropy is weakened. The magnetic permeability and the head output can be elevated in a high frequency region by lowering the magnetic anisotropy.Type: GrantFiled: November 25, 1997Date of Patent: September 7, 1999Assignee: Alps Electric Co., Ltd.Inventors: Hiroshi Yamagami, Kazuichi Endo, Kazuhiro Kaneko, Masahiro Iizuka

Patent number: 5945227Abstract: The absolute values of the apparent magnetocrystalline anisotropic energy K1 is made large to increase the absolute value of the crystal magnetic anisotropy energy by adjusting the content of Fe.sub.2 O.sub.3 in the single crystal ferrite to 50 to 52 mol % or 55 to 58 mol %, thereby the absolute value of the apparent magnetic anisotropic energy is increased. Accordingly, the magnetic pole at the demagnetization time is stabilized and noise fluctuation is suppressed to a low level.Type: GrantFiled: November 24, 1997Date of Patent: August 31, 1999Assignee: Alps Electric Co., Ltd.Inventors: Hiroshi Yamagami, Takashi Saito, Masao Aoki, Kazuhiro Kaneko

Patent number: 5904366Abstract: A folded air bag is covered with a synthetic resin cover body. A switch apparatus having a membrane switch and a back plate is disposed between the cover body and the air bag. The membrane switch is adhered to the back plate at a point in a central portion. An extension portion of the back plate is mounted to the base plate, thereby deploying outward independently from the cover at a time of expansion and deployment of the air bag.Type: GrantFiled: March 5, 1998Date of Patent: May 18, 1999Assignee: Nihon Plast Co., Ltd.Inventors: Kazuyoshi Nishijima, Kazuhiro Kaneko, Michitaka Suzuki, Toshiyuki Sugiyama

Patent number: 5899495Abstract: An air bag system is provided that limits the forward projection of the air bag and reduces production costs wherein folded portions are formed by folding the peripheral portion of a flatly spread air bag along folding lines which are provided at specified locations. The formed folded portions are constrained by stitched portions which are formed by stitching folded-down portions with thread. The air bag is then folded into a size so as to be constrained in a cover. When gas is injected from an inflator, the air bag tears the cover and projects forward and at the same time the stitched portions limit the distance by which the air bag projects forward. As the internal pressure in the air bag increases, the stitched portions break and the folded portions are unfolded so that the air bag expands radially.Type: GrantFiled: April 25, 1997Date of Patent: May 4, 1999Assignee: Nihon Plast Co., Ltd.Inventors: Naoki Yamamoto, Kazuyoshi Nishijima, Kazuhiro Kaneko, Mikio Ochiai

Patent number: 5772146Abstract: A reel device for a flat cable through which electrical component parts mounted on a steering wheel are electrically connected with electrical component parts on a vehicle body side. The reel device is disposed between the steering wheel and a combination switch mounted on the vehicle body side and comprises a generally cylindrical frame section inside which a shaft section is disposed rotatable relative to the frame section. The frame section is fixed to the combination switch, whereas the shaft section is fixedly mounted around the steering shaft. The flat cable is movably disposed in an annular cable storing space formed between the frame section and the shaft section. A generally annular guide member is movably disposed in the cable storing space and located between the cable wound on the outer peripheral surface of the shaft section and the cable wound on the inner peripheral surface of the frame section.Type: GrantFiled: December 5, 1996Date of Patent: June 30, 1998Assignee: Nihon Plast Co., Ltd.Inventors: Akio Kawamoto, Kiyoshi Watanabe, Yoshiaki Takano, Kazuhiro Kaneko
