A mirror device for a vehicle which is equipped with a mirror surface angle adjusting mechanism. In a door mirror device for a vehicle, a load is applied to a rod drive in an axial direction, a claw member elastically deforms, and an engagement valley of the rod drive rides up over an engagement projection provided at a distal end of the claw member and is moved. Here, given that angles of inclination of two surfaces of the engagement valley, at a mirror side and at a side opposite the mirror, with respect to a direction orthogonal to an axis of the rod drive, are respectively &thgr;1 and &thgr;2, &thgr;1>&thgr;2. In this way, two loads for manually moving the rod drive toward a side opposite the mirror and toward the mirror side can be made to approach substantially a same magnitude.

A mirror assembly particularly adopted as a side view mirror for a vehicle, the assembly being provided a mirror, a mounting plate for supporting the mirror, a light assembly having a lens at one end, a visor for accommodating the mirror and the light assembly. A joint element pivotally mounts a side of the light assembly to the mounting plate. The visor has a visor opening into which the lens is fitted, and a connection element for movably connecting an end of the visor opening and an end of the lens. A bias element in the form of a spring pivotally biases the end of the light assembly having the lens such that the connection element substantially closes any gap between the visor opening and the lens.

For reproducing and/or recording information from/onto an optical disc, a pickup is used to detect a target track on the disc through an optical beam. In carriage servo control, movement of the pickup is servo-controlled in the radial direction of the optical disc. In this control, a tracking error signal is produced by a preamplifier. A pulse signal is produced, in which the period of the pulse signal is set to a constant amount corresponding to the accuracy of movement of the pickup. Based on the pulse signal and the tracking error signal, a carriage control signal to move the pickup is produced. The carriage control signal is then supplied to a carriage motor by a driver, so that the pickup is moved.
摘要:
The present invention relates to ruthenium complex compound wherein a heteroatom-containing carbene compound having a six-membered ring structure is bonded to ruthenium and a process for the preparation thereof; a process for producing ring-opened cyclic olefin polymer by subjecting a cyclic olefin to ring-opening metathesis polymerization in the presence of such a ruthenium complex compound; and a process for producing hydrogenated product of ring-opened cyclic olefin polymers by hydrogenating the carbon-carbon double bonds of the above ring-opened polymers. The invention gives hydrogenated product of ring-opened cyclic olefin polymers having physical properties different from those of hydrogenated product of ring-opened polymers of the prior art. Particularly, the use of dicyclopentadiene can give a hydrogenated product of ring-opened cyclic olefin polymer excellent in heat resistance, and this product can be advantageously used as parts or formed products for medical appliances or electrical components.
摘要:
For reproducing information recorded on an optical disc, a pickup is used to detect a target track on the disc through an optical beam. In carriage servo control, movement of the pickup is servo-controlled in the radial direction of the optical disc. In this control, a tracking error signal is produced by a preamplifier. A pulse signal is produced, in which the period of the pulse signal is set to a constant amount corresponding to the accuracy of movement of the pickup. The duty ratio of the pulse signal is changed based on characteristic of the error signal, so that a changed pulse signal is produced. The changed pulse signal is multiplied by the tracking error signal, so that a carriage control signal is produced. The carriage control signal is supplied to a carriage motor by a driver, so that the pickup is moved.
