Abstract: A microcomputer 11 stays in a power saving mode until a remote control signal is input and a first interrupt signal is input to an interrupt terminal 14. When the first interrupt signal is input, the microcomputer 11 performs an intermittent operation in which the power saving mode and the normal mode are periodically alternated with each other, and ends the intermittent operation when the remote control signal is received completely. After the intermittent operation, the microcomputer 11 stays in the normal mode if the remote control signal is a power-requesting signal and stays in the power saving mode otherwise.

Abstract: An image reproduction system includes a TV set, an AV amplifier connected to the TV set, and a plurality of image output devices, such as a DVD player, a set-top box and a game console, connected to the AV amplifier. The ID information of these image output devices is displayed as a list on the screen of the TV set. The user can select any one of the image output devices from the list by using a remote control, for example. The fact of the selection is transmitted to the AV amplifier from the TV set. Upon this, the AV amplifier connects the selected image output device to the TV set, so that the image signals reproduced by the selected device are sent to the TV set.

Abstract: All port numbers are set at a server, whereas only one port number is set at a client. The client searches for the server by using the set port number. The server responds to searching by the client and notifies the client of the other port number that is not set at the client. The client establishes the communication with the server by using the notified port number. This makes it unnecessary to set all port numbers at the client. It is therefore possible to provide a server client system with time for setting a port number decreased.

Abstract: An input device includes an input circuit including a plurality of key switches connected in parallel to one another, and a control circuit including a key input terminal to which a first terminal of the input circuit is connected, and an interrupt terminal to which a second terminal of the input circuit is connected. When a key switch is turned ON, an interrupt signal is input from the second terminal of the input circuit to the interrupt terminal, whereby the control circuit transitions from a power saving mode to a normal mode. Then, the control circuit determines which one of the key switches is turned ON based on a value of a voltage applied from the first terminal of the input circuit to the key input terminal. Thus, it is possible to realize a power saving mode without having to provide a comparator.

Abstract: A turntable provided in the carousel changer has a plurality of trays provided around its rotating shaft. The turntable is provided with an annular rib including a plurality of recessed portions and a plurality of raised portions. A sensor is provided to have the rib passed therethrough and detects recessed portions and raised portions in the rib as the turntable is driven by a motor to rotate. The controller receives a detection result by the sensor and controls the motor based on the ratio of the widths of a raised portion and a recessed portion adjacent to each other in the rib. Therefore, this carousel changer can accurately stop a tray carrying an optical disk desired to be reproduced in a prescribed position.

Abstract: A remote control system includes a computer and a receiver, and allows the user to control the operation of a computer program installed in the computer.

Abstract: An uploader transmits to a server a request start notification indicating the start of a registration request and then transmits to the server a plurality of registration requests for pieces of music piece data. Upon receiving the plurality of registration requests from the uploader, the server registers the pieces of music piece data in a database in an HDD. After transmitting all the registration requests, the uploader transmits to the server a request completion notification indicating the completion of the registration requests. The server transmits an updating notification to an audio client after receiving the request completion notification. Therefore, traffic between the server and the client can be reduced when the server updates the database.
