Abstract: Gas meter includes shutoff valve, return unit, flow rate measurer, display, communication unit that communicates with an outside, controller, area information setting unit, and area information comparator. The gas meter compares, by area information comparator, a preset area information held in area information setting unit with a specified value of area information added to a remote shutoff instruction received by communication unit, and when the preset area information and the specified value of the added area information match, shutoff valve is closed.

Abstract: An Internet information displaying apparatus comprising character signal generating means for generating a character signal and displaying it on the screen of the displaying means, and character signal generation controlling means for detecting the state of transmission and reception of digital data of the digital data transmitting and receiving means, and controlling the character signal generating means so as to generate a character signal to indicate the transmission or reception state. The state of transmission or reception of the digital data of the digital data transmitting and receiving means, in other words, the state of connection to the provider is displayed on the screen.

Abstract: In a method of displaying character data in a digital television broadcasting receiver in a case where the aspect ratio of a monitor differs from the aspect ratio of a received image, the method comprises the steps of selecting, with respect to the size of characters, the size designated by the character data proportionally depending on the aspect ratio of the image and the aspect ratio of the monitor, and selecting, out of the sizes of fonts of the receiver, the size which is not more than and is closest to the corrected size, and correcting, with respect to the display position of the characters, the display position designated by the character data proportionally depending on the aspect ratio of the image and the aspect ratio of the monitor.

Abstract: An Internet information displaying apparatus, comprising: a video intermediate frequency detector (11) for extracting a first picture signal from a video signal and outputting it; a gate array (36) for converting the digital data taken in from the Internet into a second picture signal, and for compressing the second picture signal in the horizontal direction of the screen of a CRT (17); a TV picture horizontal compression unit (18) for compressing the first picture signal in the horizontal direction of the screen of the CRT (17); the gate array (36) for compressing the second picture signal in the horizontal direction of the screen of the CRT (17); a picture right and left composing unit (19) for composing the picture signals compressed by the unit (18) and the gate array (36), respectively, in a row; and switching units (14, 23) for switching the picture signal to be displayed on the screen of the CRT (17) into any of the first picture signal, the second picture signal, and the picture signal composed by the

Abstract: Light is obliquely irradiated onto the surface of a document in braille, and its reflected light is received, to obtain a first gray image. The first gray image is subjected, while being scanned in a direction corresponding to a direction parallel to the direction of light irradiation, to differentiation processing in the scanning direction, to produce a second gray image whose light and dark portions respectively produced by projected points have a particular pattern. The second gray image is subjected to such ternary-coding processing that the particular pattern of the light and dark portions respectively produced by the projected points in the second gray image is emphasized, to produce a ternary-coded image. Each of the projected points is extracted by pattern matching with respect to the ternary-coded image.
