  • Patent number: 8800948
    Abstract: A slide locking apparatus for a seat includes a first locking section with plural first locking pieces and at least one second locking section group with forward, intermediate, and rear second locking sections. When at least one of the first locking pieces locks with one of the second locking sections, another first locking piece locks with another second locking section. A first lock inhibiting section inhibits the forward second locking section from engaging any of the locking pieces when a rearwardmost locking piece is forward of a position where the rearwardmost locking piece coincides with the intermediate locking section. A second inhibiting section inhibits the rear second locking section from locking with any of the locking pieces when the forward locking piece is rearward of the intermediate locking section.

  • Patent number: 7466292
    Abstract: According to the present invention, a plasma display apparatus, which represents the luminance of one frame in accordance with a combination of plural sub-frames having luminance levels corresponding to a plurality of weighted values, additionally includes a sub-frame having a luminance level lower than the minimum gray scale level of luminance which can be represented by the number of bits in the input video data. Such plasma display apparatus turns on a desired combination of the sub-frames so as to increase the resolution of the luminance without increasing the conventional number of gray scale levels included in the input video data. In a preferred embodiment, especially when the added smaller luminance sub-frame is included in a combination of sub-frames for a low luminance area, the resolution of the gray scale of the low luminance area can be increased, and the representation of gray scale can be enhanced in a low luminance area to which the sight of a person is more sensitive.

  • Patent number: 7174802
    Abstract: An automatic transmission shifter assembly for automotive vehicles includes a shift lever, a gate plate formed with a gate passage, and a slide block having an engagement recess to be engaged with the shift lever, wherein the slide block is adapted to be moved frontwardly and rearwardly in response to the manipulation of the shift lever. The shifter assembly is provided with a noise-reducing member made of a flexible material, and attached onto the shift lever to extend from a region allowing the noise-reduction member to be brought into contact with the gate passage to a region allowing the noise-reduction member to be engaged with the engagement recess. The shifter assembly can effectively suppress hitting noises.

  • Patent number: 6724356
    Abstract: In a PDP unit, a display frame for one screen comprises a plurality of sub-frames, the luminance of each of which is determined by a sustaining pulse number. A length of one frame is calculated from the length of one cycle of a vertical synchronization signal and a sub-frame condition determination circuit determines, from the length of one frame, the number of sub-frames, the luminance of each sub-frame and a total sustaining pulse number. A load factor is calculated from an external input signal. A further circuit determines a maximum display luminance from consumed power and calculates a luminance factor, and yet a further circuit corrects the luminance drop due to a load from the total sustaining pulse number, the luminance ratio and the load factor for the respective sub-frame and calculates sustaining pulse numbers for the respective sub-frames.

  • Patent number: 6641218
    Abstract: A seat apparatus for an automobile comprises: a seat cushion which is movable between a sitting position and a position for getting into and getting out of the automobile, the position is remote forward or rearward from the sitting position; a guide device for guiding the seat cushion between the sitting position and the position for getting into and getting out of the automobile; a backrest which is rotatably connected to the seat cushion via a hinge structure; a locking mechanism which causes the seat cushion to engage and disengage with the guide device, and a lock switching device is provided on the seat cushion and the backrest. The lock switching device releases an engagement between the seat cushion and the guide device performed by the lock mechanism and when the backrest is inclined forward to the seat cushion at a predetermined angle, and engages the seat cushion and the guide device with each other when the backrest is further inclined forward so as to be substantially horizontal.

  • Patent number: 6278421
    Abstract: In a plasma display apparatus with power consumption control, a control method is provided that eliminates unnaturalness of images during power control and that holds power consumption to within a target value regardless of the type of image pattern displayed. Differences between power consumption PSA and target value PSET are summed to calculate power consumption sum value PSUM, and if PSUM is negative, brightness set value MCBC is set to its maximum value MCBCMAX. If PSUM is positive, the value calculated by the equation “MCBCMAX−PSUM×MCBCMAX/PSUM,MAX” is set as the MCBC.
