Abstract: A metal sheet tape including magnesium as a major component thereof having high electro-magnetic shield performance, high vibration absorption performance as well as high heat conductivity being wound spirally on an outer circumference of the electric cable may provide a high performance shield layer. Furthermore in an AV cable, original sounds may be recovered by forming a shield layer with winding spirally the metal sheet tape, which includes magnesium as a major component and is wound in the counter clockwise direction in the direction viewed from an IN end to an OUT end of an AV cable.

Abstract: The present invention relates to a novel shield structure for an electric cable which is able to cut-off the effect of the external noises as low as the limit thereof. A metal sheet tape including magnesium as a major component thereof having high electro-magnetic shield performance, high vibration absorption performance as well as high heat conductivity being wound spirally on an outer circumference of the electric cable may provide a high performance shield layer. Furthermore in an AV cable, original sounds may be recovered with extremely high faithfulness by forming a shield layer with winding spirally the metal sheet tape, which includes magnesium as a major component and is wound in the counter clockwise direction in the direction viewed from an IN end to an OUT end of an AV cable.

Abstract: An information display apparatus having an input unit for entering a variety of data and processing requests, a processing unit, and a display unit for displaying input data and processing results is provided. The display unit displays two or more data groups in separate display areas, and provides scrolling functions to individually scroll each display area in predetermined directions as designated by the input unit. The processing unit includes an automatic power-off function for automatically turning off power to the apparatus if it remains non-operated for a predetermined time period. The processing unit also includes a continuous search function for continuously searching data in a predetermined order, and a search stop device that automatically stops a continuous search after a predetermined amount of search or search time, thereby enabling the automatic power-off function.

Abstract: A display data secret registration drive is adapted to add secret registration data to the data in a desired row or column of table data comprising rows and columns of data and stored in a memory. When the table data is to be shown on a display, the display presents the table data other than the row or column data having the secret registration data added thereto.

Abstract: A coded information reading device for reading code pattern displayed on a CRT display unit of a television receiver and for outputing information signals corresponding to the code pattern includes a suction cup to be attached to the surface of the CRT display unit and a photo sensor integrally installed in the suction cup for reading the code pattern displayed on the CRT display unit.

Abstract: A display data processing device for processing bar code data displayed on a display screen such as a television monitor by an interlaced scanning process includes a photosensor for reading bar code data displayed on the screen, a counter circuit for counting the coded data bits read by the photosensor means to determine whether the data is displayed by an odd-number field or an even-number field and which produces a signal corresponding to the result of the determination. This signal is used in conjunction with a plurality of timer circuits which provide signals corresponding to the duration of odd and even number field scanning periods to ensure accurate storing of data in a shift register which is provided with the output signals of the photosensor.

Abstract: A data processing device for reading a code signal output from the image output screen of a video receiver. The device is provided with a read controller to synchronize the code signal reading operation with the code signal display timing of the video receiver.
