  • Patent number: 6198843
    Abstract: Colorimetric values such as L*a*b* are input from an input section to a color gamut mapping portion. A filtering process is performed on an image of the difference between the image sent by the input section and an image obtained as a result of bi-directional conversion at a converter section, and the input to the converter section is controlled so as to satisfy a requirement of minimizing an evaluation function which is defined by the sum of square norm of the filtered image as a whole and a value obtained by performing a thresholding process on norm of the difference in each pixel between images before and after the conversion at the converter section output by a gamut extracting section, obtained for the image as a whole. Device values satisfying predetermined conditions which are output of a first neural network of a first converter section to an image output section.

  • Patent number: 6178042
    Abstract: A real image mode finder includes an objective optical system and an eyepiece optical system which has at least one reflecting surface. The objective optical system includes, in order from the object side, an objective unit, a first prism and a second prism. The first prism has an entrance surface which transmits a light beam emerging from the objective unit and a transmission surface which is optically inclined with respect to the entrance surface. The second prism has a reflecting surface, situated nearly opposite to the entrance surface of the first prism, for obliquely reflecting the light beam transmitted through the first prism toward the object side, a transmitting-reflecting surface located nearly parallel with the transmission surface of the first prism, at a minute distance away therefrom, to transmit the light transmitted through the first prism and to totally reflect the light from the reflecting surface, and an exit surface.

  • Patent number: 5928098
    Abstract: A continuously variable transmission for vehicles, in which the power from a prime mover is divided by a power dividing mechanism and transmitted to a hydraulic continuously variable transmission (HCVT) apparatus and to a mechanical transmitting means for mechanical transmission of power, and the power from the HCVT apparatus and the mechanical transmitting means is collected and selectively outputted for satisfying both the maximum speed performance and the fuel consumption performance of the vehicle. A lock-up brake in the power dividing mechanism stops the rotation of the hydraulic pump of the HCVT so that the power from the input member may be mechanically transmitted to the mechanical transmitting means only via the power dividing mechanism to achieve a minimum gear ratio.

  • Patent number: 5704457
    Abstract: A driving force from a motor is transmitted through a pinion, a first gear, a second gear, a third gear, a link, a control lever, a control shaft, a parking shaft and a parking lever to a parking pole. A lost motion spring is mounted between the control shaft and the parking lever for biasing the parking pole toward a parking gear. A one-way clutch is mounted between the third gear and a housing. The one-way clutch permits the driving force from the motor to be transmitted to the parking pole and prevents the resilient force of the lost motion spring from being transmitted back to the motor.
