Abstract: A hybrid electric vehicle comprises a first motor (2) connected to an internal combustion engine (1), a second motor (3) generating vehicle drive force, and a power storage device (6). A controller (9) supplies power from the power storage device (6) to the second motor (3) in response to an accelerator pedal depression amount (B16, B42). The controller (9) calculates an available power supply to the first motor (2) by subtracting the power supply to the second motor (3) from the available power of the power storage device (6) (B28). When the target rotation speed of the engine (1) exceeds the actual rotation speed of the engine (1), power from the power storage device (6) is supplied to the first motor (2) in a range which does not exceed the available power supply (B23, B32), thereby accelerating engine rotation without decreasing power supply to the second motor (3).

Abstract: Each of a horizontal chart generating unit and a vertical chart generating unit generate eight charts #0 to #7, the bright/dark sections being placed sequentially in equal distances. Each pattern of each charts #0 to #7, is shifted little by little. Each chart #0 to #7 is sequentially projected on a screen, and each of the sensor controllers obtains an average phase difference, by obtaining the sensor data obtained by the result of measuring, from the distance-measuring sensors, and obtains the angle between an ideal screen that is vertical to a center line of distance-measuring sensors and the screen, by obtaining the distance to the two distance-measuring points on the screen, based on the obtained average phase difference. A projector control unit replaces the angles that each of the sensor controllers obtains, to inclination angles ?H and ?V of the screen, and supplies the angles to a trapezoidal correction unit.

The transformation coefficient storing unit selects a coefficient set from the selected correction table based on inclination angles ?H and ?V and supplies the selected coefficient set to a trapezoidal correction unit. The trapezoidal correction unit performs trapezoidal correction based on the supplied coefficient set.

Abstract: A trapezoidal correction unit included in a projector positions a quadrangle p?q?r?s? after correction within a quadrangle pqrs before correction, by using inclination angles v and h. In this case, the trapezoidal correction unit performs correction in a manner that the quadrangle p?q?r?s? establishes symmetry with respect to a vertical line including a light axis point k which is an intersection of a light axis and a screen, and a part or the all of the bottom side of the quadrangle p?q?r?s? contacts or is positioned near a part or the all of the bottom side of the quadrangle pqrs. The trapezoidal correction unit sets the size of the quadrangle p?q?r?s? in a manner that the area of the quadrangle p?q?r?s? becomes the largest. The trapezoidal correction unit projectively transforms the quadrangle pqrs before correction represented by an input image signal into the quadrangle p?q?r?s? after correction temporally continuously.

The angle calculation unit supplies the obtained inclination angles ?V and ?H to a trapezoidal correction unit. The trapezoidal correction unit performs trapezoidal correction by using the supplied inclination angles ?V and ?H.

The accuracy of the determined cutting forces Fm, Fs is high since they are determined from the primary component Ft less affected by disturbance and the largest axis component of the cutting force.

Abstract: A field sequential color projector includes an area sensor unit having an area sensor for photographing a screen, and an optical filter for permitting only a red light having the same color as a laser beam from a laser pointer to be input to the area sensor, and a color period/timing extraction unit which extracts timings for projecting red, green, and blue images. When a projection timing for a red image arrives while an image is projected, an MPU (Micro Processor Unit) receives a light of an image projected on the screen at that time to acquire image information, and detects a position pointed by the laser beam based on the acquired image information. Even if there exists a portion having the same color as the laser beam in the projected image, a pointed position detection device accurately detects the position irradiated by a pointing light of the laser pointer.
