Publication number: 20110207347Abstract: An unauthorized connection prevention device use with an outlet, which is electrically connectable to a connection plug arranged on a basal end of a charging cable that supplies commercial power to a power receiving connector. The unauthorized connection prevention device includes a verification circuit that performs verification to determine whether an authorized operator is electrically connecting the connection plug to the outlet. A lock mechanism switches, in accordance with a result of the verification performed by the verification circuit, between an unlocked state, which permits connection of the connection plug to an outlet port of the outlet, and a locked state, which prohibits connection of the connection plug to the outlet port.Type: ApplicationFiled: February 8, 2011Publication date: August 25, 2011Applicant: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventor: Hiroshi TSURUTA

Publication number: 20100071427Abstract: A key slot capable of accommodating an auxiliary key, which is a vehicle key other than a master key. A key lock mechanism locks or unlocks movement of the auxiliary key in the key slot, thereby allowing the auxiliary key to be taken out of the key slot in accordance with a lending condition of the auxiliary key. An invalid key return prevention unit permits the auxiliary key to be returned to the key slot in accordance with a return condition of the auxiliary key. If the return condition is met, the invalid key return prevention unit causes the key lock mechanism to lock the auxiliary key in the key slot. If the return condition is not met, the invalid key return prevention unit does not allow the auxiliary key to be returned to the key slot.Type: ApplicationFiled: September 22, 2009Publication date: March 25, 2010Applicant: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventor: Hiroshi Tsuruta

Publication number: 20100073130Abstract: A key holding device includes a key cylinder capable of retaining an auxiliary key which is a vehicle key that is not a master key. A rotor is rotatably arranged in the key cylinder. The auxiliary key is insertable into the rotor. A tumbler is rotatable with the rotor in the key cylinder. The tumbler holds the auxiliary key in a manner irremovable from the key cylinder in accordance with the rotational position of the rotor. A key lock mechanism is capable of locking the rotor in a state in which the tumbler holds the auxiliary key in a manner irremovable from the key cylinder. A control unit selectively switches the rotor between a locked state and an unlocked state by controlling the key lock mechanism so as to permit removal of the auxiliary key when the rotor is in the unlocked state.Type: ApplicationFiled: September 24, 2009Publication date: March 25, 2010Applicant: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventor: HIROSHI TSURUTA

Publication number: 20100071424Abstract: An electric lock for a glove box lid closed when a lock member is engaged with a fastening portion and allowed to open when the lock member is disengaged from the fastening portion. The electric lock includes an operation unit operated by a vehicle occupant when opening the glove box lid. A verification unit performs verification of the vehicle occupant. A lock release member pushes the lock member and separates the lock member from the fastening portion when the operation unit is operated in a state in which the verification is established. A disconnection unit integrally connects the operation unit and lock release member when verification is established and disconnects the operation unit and lock release member when not established. When verification is not established, a control unit prohibits the disconnection unit from integrally connecting the operation unit and lock release member to disable opening of the glove box lid.Type: ApplicationFiled: September 21, 2009Publication date: March 25, 2010Applicant: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventor: Hiroshi TSURUTA

Publication number: 20100019621Abstract: An ultrasonic motor according to an aspect of the invention includes at least a piezoelectric element that is an oscillator whose section perpendicular to a central axis has a rectangular length ratio, and a rotor that is rotated about the central axis as a rotation axis while being in contact with an elliptic oscillation generating surface of the oscillator. The central axis is orthogonal to the elliptic oscillation generating surface of the oscillator. The elliptic oscillation is formed by combining first longitudinal resonance oscillation in which expansion and contraction are performed in a rotation axis direction of the piezoelectric element and second twisting resonance oscillation in which the rotation axis is a twisting axis.Type: ApplicationFiled: July 14, 2009Publication date: January 28, 2010Applicant: OLYMPUS CORPORATIONInventors: Tomoki FUNAKUBO, Hiroshi TSURUTA
