  • Publication number: 20050135788
    Abstract: A recording apparatus is provided in which, when image signals are inputted from a plurality of channels and compressed and encoded before being recorded on a medium, the slow-varying-image signals are improved in their quality even if the numbers of bits for the image signals are decreased and they are recorded on the medium for a long time. The image signals inputted are converted into a single-channel image signal, sorted to be a group of a certain number of frames for each channel, and compressed and encoded for each group of a certain number of frames. When an image quality is fixed, the number of bits for the reference image at the encoding time is kept constant, but the number of bits for the difference image at that time is changed.

  • Patent number: 6378342
    Abstract: A washer-dryer has an improved efficiency of drying; namely, the drying time is shortened and the unevenness of drying is alleviated. Furthermore, vibration during operations, especially during spin-drying, is reduced. An inner tub of approximately cylindrical shape rotating around a substantially vertical axis and for receiving a wash load is housed in an outer tub. The inner tub is provided with freely rotatable agitating means at the bottom part for agitating the wash load. A motor rotates the inner tub or the agitating means. The air to be supplied through a hot air supply channel into the inner tub is heated by heating means, which air is advanced by a drying air blower into the inner tub. Control means controls each of the washing, rinsing, spin-drying and drying processes by controlling respective operations of the motor, the heating means, the drying air blower, etc.

  • Patent number: 6267360
    Abstract: A shock absorber is formed of a cylinder having a stopping surface, a piston slidably situated in the cylinder to be moved when it is pushed by a moving member, and a switching device attached to the cylinder to be actuated right before the piston abuts against the stopping surface of the cylinder. An electromagnetic valve is connected to the switching device. The electromagnetic valve has a first position, and a second position for allowing air in the cylinder to escape outwardly when the piston is moved and the electromagnetic valve is operated by the switching device. A spring cooperates with the piston to return the piston to a position before the switching device is operated when a pressing force applied to the piston is removed by retreat of the moving member after the switching device is actuated.
