Publication number: 20100052313Abstract: In a quick connection device for piping installed with a checker 40, a connector housing 20 of a quick connector 10 is formed with opening portions 74 for inserting resilient legs 58 therein through the opening portions 74 in a direction perpendicular to an axis from leading ends of the resilient legs, and inserted portions of the resilient legs 58 are held inside the connector housing 20. And, the resilient legs 58 are resiliently deformed in an axially inward direction by an annular projecting portion on an outer peripheral surface of a mating pipe at insertion of the mating pipe, to unlatch latching pawls 64 of the resilient legs 58 from corresponding latch portions of the connector housing 20, whereby the checker 40 is allowed to be removed out of the connector housing 20.Type: ApplicationFiled: December 5, 2006Publication date: March 4, 2010Inventors: Yoshimitsu Ishida, Yasuki Takenaka

Patent number: 7481463Abstract: A connecting portion of a quick connector is provided with a pair of stop arms. Each of the stop arms has an arm body that integrally includes an overhanging stop portion and an engaging pawl on a leading end portion thereof. The connecting portion is inserted in a connecting hole formed in a fluid line component until the engaging pawl engages with an outwardly directed engaging projection of a mounting portion that is provided on an opening portion of the connecting hole. A checker has a main body that is provided integrally with verifying portions. Each of the verifying portions is formed with a receiving recessed portion for accommodating the overhanging stop portion therein when the checker is disposed on an outer circumference of the mounting portion.Type: GrantFiled: March 13, 2006Date of Patent: January 27, 2009Assignee: Tokai Rubber Industries, Inc.Inventors: Yoshimitsu Ishida, Akira Takayanagi

Patent number: 7304568Abstract: In a vehicle night vision system, the display unit is activated only when an illumination level below the prescribed level has persisted for more than the prescribed period of time so that the display unit would not be activated when the low illumination level lasts only for a short period of time and the night vision system would not be required. Therefore, when the vehicle passes through a short tunnel during daytime, the display unit would not be activated and the vehicle operator is prevented from being unnecessarily distracted. On the other hand, when the vehicle passes through a long tunnel or when the sun has set and the illumination level of the road ahead is low, the night vision system is activated without fail, and assists the vehicle operator's vision.Type: GrantFiled: September 16, 2005Date of Patent: December 4, 2007Assignee: Honda Motor Co., Ltd.Inventors: Nobuko Ohkawara, legal representative, Yoshimitsu Ishida, Osamu Ohkawara, deceased

Patent number: 6523632Abstract: A vehicle capable of turning a vehicle body with a relatively small turning radius and with a good operability in a turning operation. One of front and rear pairs of left and right wheels, to which a running torque produced by a vehicle driving source is not transmitted, is arranged for rotation concerning respective axes perpendicular to the ground. For turning the vehicle body, the one pair of left and right wheels are fixed at angular positions along tangential directions of an arc which passes the axes perpendicular to the ground of the one pair of left and right wheels. At these angular positions, a rotating torque is applied to the one pair of left and right wheels to turn the vehicle body substantially about the center point of the rotating axle for running the vehicle of the other pair of left and right wheels.Type: GrantFiled: July 13, 2000Date of Patent: February 25, 2003Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Tadashi Hanaoka, Yoshimitsu Ishida, Masaru Katayama, Yasuto Shigematsu, Yoshito Hamasaki

Patent number: 6481524Abstract: A four-wheel vehicle capable of permitting a driver to perform a turning operation with a good operability. One of front and rear pairs of left and right wheels, to which a running torque produced by a driving source is not transmitted, are rotated on respective axes perpendicular to the ground. The one pair of left and right wheels are rotated from straight traveling positions taken when the vehicle is running to angular positions along tangential directions of an arc passing the axes perpendicular to the ground on a neighborhood of a center point of a rotating axle for running the vehicle of the other of front and rear pairs of left and right wheels.Type: GrantFiled: August 8, 2000Date of Patent: November 19, 2002Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Yoshimitsu Ishida, Tadashi Hanaoka

Publication number: 20020134450Abstract: A hose of low fuel permeability has a fuel permeability in a bent state with R50 not more than three times a fuel permeability in a straight state, R50 being a bent state where the hose has its longitudinal axis bent to form an arc having a diameter of 100 mm. Its low fuel permeability is achieved if the resin forming its inner wall layer has a melt viscosity falling within a certain range, which can be obtained by, for example, increasing the degree of polymerization of the resin, or grafting a specific side chain to the main chain in each molecule of the resin, or if the resin has a volume swelling degree falling within a certain range, which can be obtained by copolymerizing a monomer having fuel resistance, or blending a polymer having fuel resistance. The hose maintains its low fuel permeability even if it may be subjected to a large load of bending stress as when it is used to form a fluid conveying line.Type: ApplicationFiled: January 9, 2002Publication date: September 26, 2002Inventors: Shinji Iio, Hiroaki Ito, Yoshimitsu Ishida, Katsutoshi Mizuno, Tomohide Ito

Publication number: 20020090477Abstract: A corrugated fuel tube is manufactured by extruding an inner single layer or multilayer of a resin of high fuel impermeability, extruding an outer single layer or multilayer of a thermoplastic resin so as to cover the inner layer to form a tube having a multi-layered wall, and corrugating the tube along at least a part thereof. The surface treatment is preferably given to an outer peripheral surface of the inner layer to ensure an improved adhesion between the inner and outer layers. The tube can be made without presenting any problem caused by a difference in melt viscosity between the materials forming its inner and outer layers.Type: ApplicationFiled: November 26, 2001Publication date: July 11, 2002Applicant: Tokai Rubber Industries, Ltd.Inventors: Hiroaki Ito, Shinji Iio, Tomohide Ito, Yoshimitsu Ishida

Patent number: 5739751Abstract: A control mechanism for controlling hazard warning and turn indicator lamps in a vehicle is combined with a control lever in the vicinity of a steering wheel for easy operation. When the control lever is angularly displaced in a first direction, an elevator (displacing member) is displaced in a corresponding direction. At this time, a movable contact is also displaced into contact with hazard warning fixed contacts, turning on a hazard switch to energize turn signal lamps in a hazard warning state. When the control lever is displaced in a direction substantially perpendicular to the first direction while in the hazard warning state, a turn switch is turned on, thereby electrically canceling the hazard warning state. The hazard warning state is thus automatically canceled upon switching from the hazard warning state to a direction indicating state.Type: GrantFiled: March 20, 1996Date of Patent: April 14, 1998Assignee: Toyo Denso Kabushiki KaishaInventors: Dai Ishihara, Katsufumi Nagatome, Yoshimitsu Ishida, Kazunari Ishiguro, Norio Takahashi, Mitsuo Horie
