摘要： A tracking apparatus for helical scan video tape recorders comprises four movable video heads situated on a scanning drum such that phase compensation information can be determined using the scanner rotational information, the tape speed, and tape position. The phase compensation information is used to adjust the video heads thereby reproducing high quality video signals with smooth movement pictures from varying speed helical scan video tape recorders.

摘要： At least three heads are mounted on a rotary drum. Between the first and third heads which are located in close proximity to each other and have different azimuth angles, a minute height difference is formed in the rotation shaft direction of the rotary drum. Signals of a plurality of data rates are recorded and reproduced by using the first and second heads or the first and third heads. Two heads having the same azimuth angle are disposed on the rotary drum so as to be opposed each other at a central angle of 180°. In search speed reproduction, search data are reproduced by the two heads. Tracks are divided in the unit of plural tracks so as to form track sets. Search data areas of each track set are disposed at a position of each track which is separated from the edge of a tape by a predetermined distance. In search speed reproduction, the phases of the tracks and the heads are controlled, and all effective data of the search data areas are reproduced by plural scans of the heads.

摘要： A magnetic head driving apparatus makes it possible to effect a correct positioning operation at the assembly of the magnetic head, and also, to effect the correct measurement of the gap positions of the magnetic head. Also, the magnetic head is immune to the influence of the leakage flux of the magnetic circuit. Coil bobbins are mounted in a first gimbal spring and a second gimbal spring and the head has a projection in its lower end portion. The projection portion is extended through the hole of the first yoke. The head base is secured with a fixing member in the projection portion. A head base extending portion extending in a radial direction is formed in one portion of the external periphery of the head base with a magnetic head being mounted on its tip end. A sensor object showing the gap position of the magnetic head is formed in one portion of the head base extending portion.

摘要： A communication system includes a device and a server connected to the Internet, which transfers communications between the device and a terminal connectable to the Internet via the server. The device periodically transmits a notice packet to the server. The server transmits a connection request packet to the device in reply to the notice packet when a transfer to the device is requested from the terminal. The device transmits a TCP connection request to the server when receiving the connection request packet from the server. The server accepts the TCP connection request transmitted from the device to the server in reply to the connection request packet, to establish the TCP connection. Thus, the server transfers communications between the terminal and the device on the TCP connection after the TCP connection is established.

摘要： A system includes electronic equipment, an information processing device and a server device. The electronic equipment sends first address change confirmation information containing first address information to the information processing device. The information processing device sends second address change confirmation information obtained by writing second address information in the received first address change confirmation information. The server device determines that the first address information and the second address information, which are contained in the received second address change confirmation information, agree with each other, and updates the address information to new one when the first address information and the second address information do not agree with each other. With such a system, electronic equipment can hold up-to-date address information of the information processing device with extremely light processing at the side of the server device and with small load of communication.

摘要： The invention is directed to a control system which controls an apparatus using a network such as an IEEE 1394 high-speed serial bus, and aims at making it possible for an old control apparatus to control a new controlled apparatus even when the new controlled apparatus is connected to the old control apparatus which does not support control of the new controlled apparatus. An HDR 4 is controlled by a first DTV 1 and a second DTV 2 via an IEEE serial bus 5, an HDR 45 performs a predetermined operation, a main subunit 40 activates the HDR 45 in response to an instruction which is from one or a plurality of the first DTV 1 and the second DTV 2 and directed to the HDR 4, and an auxiliary subunit 42 disguises as if it were an apparatus other than the HDR 4 and directly or indirectly activates the HDR 4 in response to an instruction which is from the first DTV 1, the second DTV 2 and is directed to an apparatus other than the HDR 4.
