Abstract: This invention is relative to an image information display apparatus in which a large-sized image can readily be recognized even with use of a small-sized display unit such as is provided in a portable telephone set or in a mobile computer. It is assumed that an observer (user) 122 is about to recognize an image of a larger size 121 using an image information display apparatus 124 having a display 123 of a smaller size. When the observer 122 moves his or her hand 126, a partial area 125 of an image demonstrated in the display 123 is actively changed. This permits the image of a larger size 121 to be comprehended readily in its entirety. The image of a larger size 121 can readily be recognized by having the hand movement matched to the movement of the display image (partial area 125 of the image), based on perceptual characteristics of the human being.

Abstract: Provided is a thin slide unit which allows, in a case where two ball plates each formed with a track-like ball groove are combined to thereby construct an endless circulation path for balls, by merely directly connecting the two ball plates without using a guide plate, balls to smoothly circulate, and a slider to smoothly reciprocate with respect to a guide rail. An endless circulation path for the balls of the slider is formed such that the two ball plates each formed with the track-like ball groove are caused to face each other, and that the ball plates are directly connected. Peripheral sides of the two ball plates oppose to each other, to thereby form a load opening portion for causing the balls in the endless circulation path to contact a rolling groove of the guide rail, and form a scooping-up portion for raising the balls from the rolling groove to guide the balls into the endless circulation path.

Abstract: An electronic device that prevents a failure caused by a temperature drift of an angular velocity sensor, and a signal compensation system and a signal compensation method for compensating for the temperature drift are provided. The present invention provides a mechanism including an angular velocity sensor that outputs a first signal in accordance with a rotational angular velocity. The device stores in advance data of a second signal normally output by the angular velocity sensor while in a stationary state, detects a stationary state and extracts the difference between the first and second signals when the stationary state is detected. The device thereby compensates for the first signal based on the extracted difference signal. A display unit in the device scrolls an image based on the compensated signal. This prevents a failure caused by the temperature drift of the angular velocity sensor.
