摘要:
The semiconductor laser device includes a signal light diffraction grating, and a light receiving portion having a pair of photodiodes extending as two strips with a parting portion or a zonal gap interposed therebetween and receiving a focus error detecting beam from the signal light diffraction grating. The light receiving portion is arranged such that its longitudinal direction is orthogonal to the direction of diffraction grooves of the signal light diffraction grating. The pair of photodiodes is arranged such that a spot of the focus error detecting beam moves, due to temperature changes, in a range essentially limited to the parting portion therebetween. Thus, a semiconductor laser device and an optical pickup apparatus suppressing focus errors due to temperature changes and preventing reduction in signal strength can be obtained.

In a CATV system, channel identifying data is incorporated in each transmitted channel, and subscriber terminals return such data to the CATV center to indicate the channel actually being received. Further, the channel identifying data is compared to the channel selected, and when a proper comparison exists a sweep voltage is held at a predetermined level for the particular channel, to control frequency conversion at the terminal.

Video signals for television are effectively scrambled and may later be descrambled without the presence of annoying visual disturbances by the introduction of a superposed distorted sine wave in synchronism with the horizontal synchronizing signal, in a "gray sync" mode of operation. Thereafter, the received signal may be normalized and descrambled by compensatory and synchronous modulation. Advantageously, the sinusoidal variation may be imposed both upon aural and visual components of the signal, and the aural AM signal may be utilized as a reference in descrambling the visual component.

A floor board positioned in the foot area of an occupant seated in an occupant seat is allowed to be driven up or down. In an automobile movable floor apparatus, a floor board 5 that covers the upper face of an automobile body floor 3 and a raising-lowering drive mechanism 6 that drives the floor board 5 to be raised or lowered are provided in the foot area of an occupant seated in an occupant seat 4, and a toe board portion 8 sloping down to the rear and a floor base portion 9 that extends toward the rear of the automobile body and is continuous with the rear end of the toe board portion 8 are provided in the automobile body floor 3. The floor board 5 includes a toe board corresponding portion 18 that corresponds to the toe board portion 8 of the automobile body floor 3, and a floor base corresponding portion 19 that corresponds to the floor base portion 9, and the toe board corresponding portion 18 and the floor base corresponding portion 19 are formed in a flattened V-like shape when viewed from the side.

Disclosed is a movable floor apparatus for a vehicle, which comprises a movable board 5 disposed beneath feet of an occupant seated in an occupant seat 4, a drive source 6 disposed below the occupant seat 4, and a driving-force transmission mechanism 7 adapted, according to a driving force of the drive source 6, to input a force directed in a selected one of frontward and rearward directions of a vehicle body, into a rear portion of the movable board 5. The movable board 5 is supported in such a manner as to be selectively displaced upwardly and downwardly in response to respective ones of the frontward and rearward forces input from the driving-force transmission mechanism 7. The movable floor apparatus of the present invention makes it possible to allow a lowermost height position of a movable board to be set at a lower level so as to cope with various seating postures with enhanced flexibility.

A ventilated disk used in automobiles and industrial vehicles includes a pair of mutually opposing disk portions, a plurality of radially extending ribs integrally formed with the disk portions and interposed therebetween, and at least one annular damping member. Formed in each rib is at least one radially extending oblong hole which passes through the rib in the circumferential direction. The oblong holes in the respective ribs form at least one circular array along a circular whose center is the center of the disk. The annular damping member(s) extends/extend through the oblong holes forming the annular array(s) and is in contacting engagement with the outer end portion and side portion of each ablong hole.
