    Abstract: A printed wiring board device used for electronic equipment, such as the information equipment, etc. A printed wiring board (10) has a power source layer (11) and a ground layer (12) and is mounted with active elements (3 and 4), such as digital ICs, etc. A first capacitor (1) which conductively couples the layers (11 and 12) with each other at a high frequency is provided in the peripheral section of one end side or the other end side of the section of the board (10) where the layers (11 and 12) are faced to each other. Second capacitors (2) which respectively supply transient currents to the active elements (3 and 4) are provided between the power supply pins (3V and 4V) of the elements (3 and 4) and the ground layer (12) near the elements (3 and 4). Therefore, the electromagnetic radiation caused by the power source layer (11) and the ground layer (12) of the printed wiring board (10) can be suppressed easily and remarkably.

    Abstract: Disclosed is an optical recording device of a phase change type including at least an optical recording medium having a recording layer formed of a recording material of a phase change type, and a control unit for controlling a unit laser beam, which is to be radiated for writing information onto the optical recording medium to form a recording mark, in such a manner that, when the unit laser beam is divided into front and rear portions with the middle point of the radiated portion of the recording medium as the boundary, the quantity of energy of the rear portion of the unit laser beam is greater than that of the front portion thereof. Also, in the optical recording device, when a recording mark is formed according to a multi-pulse recording system using a multi-pulse laser beam, the multi-pulse laser beam, at least the first pulse thereof is controlled so as to satisfy a similar condition as described above and after then the controlled multi-pulse laser beam or the controlled first pulse thereof is radiated.

    Abstract: A printed wiring board is provided which can be applied even to circuit boards operating at high speed, and which can suppress electromagnetic wave radiation, and which can suppress a deterioration in density of mounting. At the printed wiring board, a first signal wire layer, a first ground layer having a first power source wire, a second ground layer having a second power source wire, and a second signal wire layer, are laminated. The first ground layer and the second ground layer are interlayer connected by many via holes. Return current, of signal current flowing through a signal wire, flows in the first ground layer, and a path of the return current is cut midway therealong at a position of the first power source wire. However, the return current is detoured by the via hole to the second ground layer, and flows thereat.

    Abstract: A seat reclining device has a torsion spring for a cam, and a plurality of guide-protrusion pairs formed integral with the inside face of a stationary member for guiding movement of tooth blocks into and out of meshed-engagement with an internal tooth of a movable member. Two opposing circular-arc concave portions are formed on opposing faces of two circumferentially adjacent guide-protrusion sets. A space between the concave portions is dimensioned to be wider on a radially outward side for defining a spring accommodation space, and dimensioned to be narrower on a radially inward side for forming circumferentially-opposing convex portions. Two spring hooks engage with the respective convex portions under preload. One of the hooks is also engaged with the cam for forcing it in its locked direction. An anti-rotation protrusion is formed on the outside face of the stationary member at a position conforming to the spring accommodation space.
