    Abstract: This invention has an object to provide speed control method and device for an optical head in which a decelerating operation and so on for the optical head is carried out at an uniform deceleration or acceleration mode at high speed, and a speed control is carried out sufficiently accurately with excellent seekability and simple construction. The speed control device for the optical head according to this invention is so constructed that in the speed control of the seek operation of the optical head using feedback of a difference signal between a reference speed signal and a speed detection signal, the reference speed signal is switched to a ground level when a residual track number is below a predetermined value, and the optical head is pulled into a tracking servo operation when a predetermined time has elapsed since the switching time of the reference speed signal to the ground level.

    Abstract: A printed circuit board includes a ground layer, a power source layer, a signal wiring layer, an insulating layer and an electromagnetic radiation suppressing member. The power source layer is provided to be opposed to the ground layer. The signal wiring layer transmits a signal in a predetermined frequency domain. The insulating layer insulates the ground layer, the power source layer and the signal wiring layer from one another. The electromagnetic radiation suppressing member is provided to cover a circumferential edge of the insulating layer. The electromagnetic radiation suppressing member has a negative dielectric constant and a positive magnetic permeability in a frequency domain including the predetermined frequency domain.

    Abstract: A vehicle seat reclining apparatus comprises a base member to be connected to one of a seat cushion and a seat back, a rotation member which is to be connected to the other of the seat cushion and seat back, which is arranged to rotate relative to the base member and which includes an internal gear, a regulating member to regulate axial movement of the rotation member relative to the base member, and a locking setup which includes an external gear and which is arranged to move between a lock position to engage the external gear with the internal gear and an unlock position for disengagement. The base member includes an outer circumferential portion defining a circular recess, the rotation member includes an outer circumferential portion including a cylindrical portion fit rotatably in the outer circumferential portion of the base member. The outer circumferential portion of the rotation member further includes a flange portion which projects radially outwards from the cylindrical portion, which is placed axially between the regulating member and the outer circumferential portion of the base member and which includes a side surface facing away from the base member and servings as a sliding regulation surface set in sliding contact with the regulating member.
