  • Publication number: 20210108717
    Abstract: A gear shift operation device for a vehicle to which a multiple-stage automatic transmission is mounted, is provided. By a control lever being manually operated in a range switchable mode, a range position is switched at least between a D-range where automatic transmission is performed and an R-range, and by the control lever being manually operated in a manual transmission mode, a gear change is performed. An operation reaction force when the control lever is manually operated is set larger when the gear change is performed in the manual transmission mode than when the range position is switched in the range switchable mode.

  • Patent number: 10946856
    Abstract: Provided is a vehicle drive system capable of suppressing a feeling of acceleration drop and free running, thereby improving vehicle riding comfort. The vehicle drive system includes: an internal combustion engine for driving a primary drive wheel; a stepped variable transmission; an assist motor for driving a secondary drive wheel; and a motor control device for controlling the assist motor, wherein the stepped variable transmission is a seamless-shift transmission configured such that a drive force to be transmitted therethrough is interrupted during shifting down, but not substantially interrupted during shifting up, and the motor control device is operable, during the shifting down by the stepped variable transmission, to cause the assist motor to generate a drive force to compensate for the interruption of the drive force.

  • Patent number: 8775873
    Abstract: In a data processing apparatus, when an instruction for starting validation is provided, or when definition information is updated, data input from a data source is collected, and a process for narrowing down of the collected data is executed. In the data narrowing process, by extracting records and items as process targets according to the definition information that defines the operation of the apparatus, the number of data items used for validation is reduced. Then, the operation is validated using the narrowed data. In the operation validation process, a virtual transfer destination of output of data is provided within the apparatus, and the data is output to the virtual transfer destination, for comparison with the output data, whereby the validation of the operation is performed.

  • Patent number: 4998800
    Abstract: An optical low pass filter for use in an imaging device including an objective lens and a solid state image sensor forming a plurality of picture elements thereon, which filter comprises a diffraction grating disposed between the objective lens and the solid state image sensor. The diffraction grating is of a type which the periodicity of an image of the diffraction grating projected onto the solid state image sensor by the objective lens is selected to be twice or 1/n of the periodicity of the picture element, wherein n represents an integer.

  • Patent number: 4525742
    Abstract: A two-dimensional solid-state image sensor device comprising a plurality of picture cells two-dimensionally arranged in column and row directions. Each cell has a static induction transistor having drain and source regions disposed on opposite sides of a high resistance semiconductor channel region, and a gate region adjacent to the channel region to control a current flowing between the drain and source regions, and a transparent electrode disposed via a capacitance on at least a portion of the gate region, in a manner that light is incident through the transparent electrode to the gate region in which the charge produced by the light excitation is stored to control the current. Selection lines connected to the gate regions in each column in common via the capacitances are sequentially selected.
