  • Publication number: 20100071427
    Abstract: 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.

  • Publication number: 20100073130
    Abstract: 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.

  • Publication number: 20100071424
    Abstract: 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.

  • Publication number: 20100019621
    Abstract: 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.

  • Publication number: 20100000588
    Abstract: A cleaning device includes: a supply nozzle that supplies cleaning liquid to inside of a vessel holding liquid for cleaning the inside of the vessel and is arranged to have a space between an outer wall surface of the supply nozzle and an entire inner wall surface of the vessel when the supply nozzle is inserted into the vessel; and a discharge nozzle that has an end positioned at an upper portion of the vessel and discharges the cleaning liquid supplied by the supply nozzle to outside of the vessel. The supply nozzle has an inner diameter area larger than an area of a section where the liquid is held on a cross section of the vessel including a part of the supply nozzle inserted into the vessel.

  • Publication number: 20090309696
    Abstract: A vehicle function restriction system for installation in a vehicle. The vehicle includes a master key allowed to activate any function of the vehicle. The system includes a valet key mounted in the vehicle and configured to dismountable from the vehicle to be lent to a person to whom the vehicle is lent. A restriction setting unit sets the vehicle in a restriction state when the valet key is dismounted from the vehicle. The restriction setting unit sets at least one restricted vehicle functions which is not activated by the valet key, in accordance with the person to whom the vehicle is lent.

  • Patent number: 7369308
    Abstract: A total internal reflection fluorescence microscope includes a light source which generates laser light having a plurality of wavelengths, a focal optical system which irradiates the laser light from the light source on a specimen at a predetermined incident angle via an objective lens and which generates evanescent illumination, a fluorescence observation unit which observes fluorescence generated from the specimen due to the evanescent illumination, an incident angle adjuster which adjusts the incident angle of the laser light irradiated on the specimen, and a controller which controls the incident angle adjuster such that the amount of the permeation depth of the evanescent light is the same when the wavelength of the laser light from the laser light source is switched.
