Abstract:
A current drive apparatus operates a plurality of loads by applying a current thereto. The apparatus includes a plurality of output terminals (Tout) to which the loads are respectively connected. A single current generation circuit (10A) outputs an operating current having a predetermined current value. A plurality of current storage circuits (30A) are provided in accordance with the respective output terminals, sequentially fetch and hold the operating current and simultaneously output the drive current based on the operating current to the respective output terminals. The operating current has a current value according to an input signal. The current storage circuit (30A) includes a voltage component holding section which fetches the operating current outputted from the current generation circuit and holds a voltage component corresponding to a current value of the operating current.

Abstract:
A display device includes a display panel having display pixels arranged in a matrix, and a display area capable of displaying in color. A display mode of the display panel is switched to either a full-screen display mode in which an image is displayed in the entire display area or a partial display mode in which an image is only partially displayed in the display area. The display area of the display panel is set while dividing the display area into a partial display area in which an image is displayed and a background display area in which an image is not displayed in the partial display mode. An image is displayed in the partial display area. A display color of the background display area is set.
Abstract:
In carrying out data communication by use of a communication network where accounting is made according to a data amount, the start and end of transmission/reception of a set of objective data to be transmitted/received are recognized, and the amount of packets transmitted/received from the start to the end of transmission/reception of the set of objective data to be transmitted/received is measured, and thereby a communication charge is calculated, and it is judged whether or not the calculated communication charge has reached a warning money amount specified by a user, and when it is judged that the calculated communication charge has reached the warning money amount, a warning to that effect is given to the user.
Abstract:
A digital still camera combines a display pattern received from a printing apparatus and a photographed image with each other, and displays the resultant image on a viewfinder. A user adjusts the balance between the display pattern and the image of the object both being displayed on the viewfinder, and depresses a shutter release button. The digital still camera fetches the photographed image. The digital still camera sends to the printing apparatus the fetched image and a pattern name specifying the display pattern used at the time of photographing. The printing apparatus combines the decoration pattern specified by the pattern name and the image received from the digital still camera into composite image data. The printing apparatus prints the composite image data.
Abstract:
Pattern data-like illustrations is stored in a ROM (24) in a printer (200). This pattern data is sent via a communication cable (30) to a digital camera (100) from the printer (200). In the digital camera (300), image data representing a still picture stored in a compressed form in an image memory (9) and pattern data sent from the printer (200) are both expanded by a compressing/expanding section (8) after which they are synthesized with each other, and an image corresponding to the synthesized data is displayed on a color LCD (19). This synthesized data is compressed by the compressing/expanding section (8), and is then sent to the printer (200) from the digital camera (100) via the communication cable (30). The printer (200) expands the compressed synthesized data and then activates a color printer section (26) to print an image corresponding to the expanded synthesized data on a recording sheet.
Abstract:
A movement measuring device determines the speed of the body's specific movement on the basis of the maximum value of the acceleration sensed by an acceleration sensing unit attached to the body, when the body has made a specific movement. For example, when th e player wears the device on his arm and makes a punching motion, the punching speed is found from the maximum acceleration resulting from the punching action. Furhtermore, a game device obtains data indicating the magnitude of a specific movement of the body, on the basis of the acceleration sensed by an acceleration sensing unit, and then decides the outcome of the game is decided on the basis of the strength and weakness of the punch. This enables the user to easily play a fighting sport game involving the player's actual punching motions anywhere.
Abstract:
A data storage device comprises a controller and a semiconductor chip which includes a nonvolatile semiconductor memory having plural storage areas into each of which data is stored, a store instruction signal input terminal to which a store instruction signal is inputted, a storage controller for storing data into the semiconductor memory when receiving a store instruction signal through the store instruction signal input terminal, a read instruction signal input terminal to which a read instruction signal is inputted, and a read controller for sequentially specifying one of the storage areas in the semiconductor memory each time it receives a read instruction signal through the read instruction signal input terminal and then reading the data stored in the specified storage area. The controller includes a specifying data storage for storing specifying data that specifies one of the storage areas, a store instruction signal output circuit for outputting a store instruction signal to the store instruction signal input terminal of the semiconductor chip, and a read instruction signal output circuit for outputting a read instruction signal corresponding to the specifying data stored in the specifying data storage to the read instruction signal input terminal of the semiconductor chip.
Abstract:
An FM broadcasting station (5) broadcasts paging ID by multiplexing it on FM broadcasting radio waves in a subframe period assigned in advance to an FM radio receiver 1b (to 1d) to be paged, and broadcasts, as program data, message data directed to the FM radio receiver 1b (to 1d) to be paged. The FM radio receiver 1b (to 1d) repeatedly and intermittently receives the paging ID broadcasted from the FM broadcasting station (5), in the subframe period assigned to itself in advance. When the received paging ID is its paging ID, the FM radio receiver 1b (to 1d) generates an alarm. Thereafter, a user selects a program on which the message data directed to the FM radio receiver 1b (to 1d) to be paged is broadcasted, and views the message data which is the program data displayed, thereby obtaining the message data directed to the FM radio receiver 1b (to 1d).
