    • In a digital-watermark superposing apparatus and a digital-watermark detecting apparatus, a plurality of DCT coefficients for respective frequency components are generated by subjecting video data to a two-dimensional DCT transform for each pixel block consisting of a predetermined number of pixels, and the value of at least one of the DCT coefficients is quantized in accordance with a quantization rule corresponding to the information so as to obtain a quantized DCT coefficient. A two-dimensional inverse DCT transform is performed with respect to the DCT coefficients in which the at least one DCT coefficient thereof is replaced with the quantized DCT coefficient, so as to obtain digital-watermark superposed video data in which the digital watermark corresponding to the information has been superposed on the video data. At this juncture, the digital-watermark superposed video data is selected and outputted concerning a section in which a video pattern due to the video data is not flatter than a predetermined video pattern, while, instead of the digital-watermark superposed video data, the video data is selected and outputted as it is concerning a section in which the video pattern due to the video data is flatter than the predetermined video pattern.

    • A speaker device is capable of accurately generating sound even within a high audio region, without high sound pressure even when generating a large sound. The speaker device includes a sound-producing vibrator having a vibrating body which is, for instance, a semi-spherical piezoelectric ceramic. Electrodes are provided on both surfaces of the vibrating body. An input signal from an amplifier is input between the electrodes so that the vibrating body is vibrated and sound is produced. The resonant frequency of the sound-producing vibrator is set higher than about 20 kHz, which is the upper limit of the human audible range. Furthermore, the thickness of the vibrating body is increased and its mass is increased.

    • An emergency locking scat hinge device includes an inner and outer members defining a plurality of chambers therebetween, each having a relatively wide central part and end parts which get progressively narrower circumferentially away from the central part, a rolling member received in each of the chambers, a resiliently supported retaining member which retains each of the rolling members in the side central part of the corresponding chamber, and an acceleration sensitive locking device which actuates the retaining member so as to cause the rolling members to wedge between the inner and outer members. Because this seat hinge device permits free rotation under normal condition but prevents the relative rotation in a high acceleration situation, it can effectively increase the mechanical strength and rigidity of a seat back against tilting particularly when it is used on one side of a vehicle seat while a normal recliner hinge device is used on the other side of the vehicle seat.
