  • Patent number: 6904623
    Abstract: A protrusion of the plug lid out of a bath tub is restricted to prevent the plug lid from being a hindrance, and water-tightness of the plug is improved. The plug lid is dropped into a notch formed in such a way that the circumferential edge of the plug lid becomes lower than the bottom surface of the bath tub. The packing closely contacts a packing close-contact surface narrowed from the bottom surface of the notch in a downward direction. The bottom part of the notch is formed into the horizontal plane and the plug lid is supported while it is not inclined under application of weight (such as a hydraulic pressure or an artificial pressure applied by a user) and the packing is protected from unnecessary crushing force.

  • Publication number: 20040019965
    Abstract: A protrusion of the plug lid out of the bath tab bottom part is restricted to reduce a possibility in which the plug lid becomes a hindrance and a water-tightness at the plug is improved. The plug lid is dropped into the notch formed in such a way that the circumferential edge of the plug lid becomes lower than the bottom surface of the bath tab. The packing is closely contacted with the packing close-contact surface narrowed from the bottom surface of the notch in a downward direction. The bottom part of the notch is formed into the horizontal plane and the plug lid is supported while it is not inclined under application of weight (a hydraulic pressure or an artificial pressure applied by a user) and a non-required crushing force is prevented from being acted on the packing.

  • Patent number: 5917790
    Abstract: Different tracks on an optical information recording medium are irradiated with first and second light spots for auto-tracking. The light of the first light spot via the recording medium is detected to produce a first detection signal and light of the second light spot via the recording medium is also detected to produce a second detection signal. On the basis of a difference between the first and second detection signals, a signal used for performing tracking control of a third light spot for recording or reproducing information is generated. When recording or reproduction of information is effected on/from one of a first recording medium having a track pitch P.sub.1 and a second recording medium having a track pitch P.sub.2 and the first and second recording media satisfy a relation P.sub.1 -P.sub.

  • Patent number: 5747715
    Abstract: An electronic musical apparatus employs a tone-generator section containing a plurality of tone-generator channels, each consisting of a vowel generation unit and a consonant generation unit which operate based on formant sound synthesis, so that a song is automatically swung based on lyric data and performance data. If a syllable within words of a lyric designated by the lyric data consists of a consonant and a vowel, the consonant generation unit generates the consonant with respect to a consonant sounding time which is set in advance whilst the vowel generation unit generates the vowel to follow the consonant. If generation of multiple syllables is allocated to a desired single note within notes corresponding to a melody designated by the performance data, the multiple syllables are sequentially generated during a sounding time of the desired single note. A human operator is capable of inputting words of a lyric to form the lyric data by using a computer keyboard.

  • Patent number: 5726963
    Abstract: An information reproduction apparatus is provided with a reproduction signal processing system for reproducing digital information recorded on an information track of a recording medium by a pit edge recording method and for reproducing the digital information by converting a reproduction signal read out from the recording medium into a binary signal after the reproduction signal is subjected to AC-coupling. The information reproduction apparatus is further provided with a phase compensation circuit arranged in the reproduction signal processing system to compensate for a phase distortion of the reproduction signal under the influence of the AC coupling.

  • Patent number: 5703311
    Abstract: An electronic musical apparatus is designed to sing a song based on performance data which indicate a melody originally played by a musical instrument. Herein, the apparatus contains a formant tone generator and a data memory which stores a plurality of formant data, lyric data and melody data. Formant synthesis method is employed for voice synthesis to generate voices based on the plurality of formant data selectively designated by the lyric data so that the voices are sequentially generated in accordance with words of a song. Thus, the song is automatically swung by sequentially generating the voices in accordance with a melody which is designated by. the melody data; and the voice synthesis is controlled such that generation of the voices temporarily stopped at timings of pausing for breath. Moreover, the data memory can store formant parameters with respect to each phoneme, so that the formant tone generator can gradually shift sounding thereof from a first phoneme (e.g.

  • Patent number: 5499226
    Abstract: In an optical information reproduction apparatus, digital information recorded as an optical mark on an optical information recording medium is reproduced in the following manner. A light beam is applied to the recording medium, and the obtained reproduction signal is binarized. The binary reproduction signal is sampled by a sampling clock which is generated by a PLL control signal generator, and is synchronized with the binary reproduction signal so as to reproduce the digital information. The PLL control signal generator achieves synchronization based on the leading and trailing edges of a change point of the binary reproduction signal.

  • Patent number: 5189659
    Abstract: An apparatus and a method for recording and reproducing an information signal onto an optical recording medium are disclosed. The apparatus includes a laser light source for radiating a laser beam onto the optical recording medium, a laser driver for driving the laser light source and a device for moving the medium relative to the laser beam. The laser driver controls the laser light source to selectively perform continuous light emission or intermittent light emission with a sufficiently higher frequency than that of the information signal during reproducing. By adopting the light intermittent emission of the light source, the formation of pits with some errors can be prevented and the reliability of the recording and reproduction can be enhanced.
