摘要： Collision-energy-absorbing means of an impact-absorbing steering column apparatus includes guide slots 31a1 and 31b1, guide slots 31a2 and 31b2, and transition portions 31a3 and 31b3, as well as energy-absorbing members 36 and 37, so as to change absorption load for secondary collision energy. A collar 42 plastically deforms the energy-absorbing member 36 or 37, thereby absorbing secondary collision energy of an occupant in the event of a collision of a vehicle. The guide slots 31a1 and 31b1, the guide slots 31a2 and 31b2, and the transition portions 31a3 and 31b3 change an absorption load for secondary collision energy dependently on the direction of a secondary collision of the occupant with the steering system.

摘要： An optical pick-up apparatus for writing and/or reading information on and/or from an optical record medium including a light source, an objective lens projecting a light beam emitted by the light source onto the optical record medium, a holding member holding the objective lens movably in a focusing direction to perform a focusing control, a carriage to which the holding member is secured, a supporting mechanism for supporting the carriage movably in a tracking direction to effect a tracking control as well as an access control, and a driving member moving a movable member including the objective lens, holding member and carriage in the tracking direction. The supporting mechanism includes guide rails extending in the tracking direction and slide bearings formed in the carriage and coupled with the slide bearings. A coefficient of static friction of the movable member is set to a value not larger than 0.25.

摘要： A control circuit for use in an optical disk apparatus, which includes a carriage provided with a focus moving mechanism for supporting an objective lens; a carriage driving circuit for driving the carriage; and a tracking error detecting circuit for detecting a tracking error signal which represents a displacement of the light beam form the center of the information track. In the control circuit, a tracking control loop for performing a tracking control by feeding back a dc-component and ac-components, with frequencies which are not more than 10 kHz, of the tracking error signal to the carriage driving circuit is formed. Further, a filter device for attenuating the gain of the tracking control loop correspondingly to a frequency in the vicinity of a resonance frequency in a direction, in which the focus moving mechanism or the carriage crosses the information track, is provided in the tracking control loop. Moreover, the open-loop or overall gain crossover frequency of the tracking control loop is not less than 2 kHz.
