A redundancy gateway system that can avoid short interruption of data communication caused by system switching in gateway units configured in a multiplex manner for a plurality of systems, and that can maintain the communication state prior to the system switching and avoid degradation of communication quality. A duplicate of a received packet is generated, thereby supplying the packet of the same content to a configuration of gateway units. For each packet, a common write pointer corresponding to identification information appended to the packet is generated. Each gateway unit writes the packet to its own jitter buffer in accordance with the common write pointer corresponding to each supplied packet, sequentially reads out the written packet from the jitter buffer, and generates a TDM signal. One of the gateway units is selectively switched and only the TDM signal generated by the one gateway unit is supplied to a TDM network.

A strategy board game is disclosed. The board for the game or playmat is comprised of several distinct regions each with a specific purpose and/or rules associated with the region. The Battlefield region is where opposing players challenge one another with various game pieces. There is also a region for keeping certain game pieces while they await to be summoned to the Battlefield. Another region, the Graveyard, is were game pieces are placed after such game pieces are taken by an opponent. Another region of the playmat is designated for the storing of currency used during play. Certain game pieces have fixed properties and other have properties that can be changed by the player during the course of the game at strategic times. A player can change the properties of a game piece by paying the cost associated therewith using the currency he or she has earned by moving game pieces and/or taking an opponents game pieces. The game can be won by capturing a special game piece of the opponent; by moving a special game piece into across the length of the playmat and into the opponent's area for storing game pieces which have not been summoned; by changing the properties of a special game piece or through the surrender to the opponent.

A laser light beam generated from a light source is divided by a diffraction grating into a plurality of light beams, i.e., a single main beam to be used for recording information and plural auxiliary beams distributed on two imaginary straight lines crossing each other. One of the straight lines extends parallel to tracks of a recording medium. The resultant divided beams are converged to be irradiated onto a recording medium, and reflected components, from the recording medium, of the beams are received by corresponding light receiving elements. Thus, the main and auxiliary beams distributed on one of the two imaginary straight lines are used to perform focusing and tracking. Further, one of the two auxiliary beams distributed on the other straight line are used to determine whether a track where information is to be recorded is a blank area or not, and the other of the auxiliary beams is used to verify whether the information has been recorded correctly.

In an optical information recording and reproducing apparatus, information is recorded or reproduced by moving a recording medium relative to an optical head. In order to execute information recording onto the medium in the course of the relative movement involving acceleration and deceleration, the generation timing and intensity of a light beam to be generated in correspondence with the information to be recorded are controlled in response to a varying speed of the relative movement so that data pits to be formed in the recording medium can be standardized in pitch and size irrespective of the relative movement speed. Also, in order to permit information reproduction from the medium in the course of the relative movement involving acceleration and deceleration, reproduction timing of data read by the optical head is set in synchronism with variation in the relative movement speed so that the data can be reproduced at proper timing irrespective of the relative movement speed. With such arrangements, there can be achieved a highly increased information recording/reproduction speed, extended information recording area, reduced size and cost of the apparatus, and reduced power consumption in the apparatus.

Information is recorded and reproduced by making a light beam traverse guide tracks to reach a target track. In moving the light beam to the target track, a tracking error signal is supplied to the inverting input terminal of a comparator to compare it with a potential at the non-inverting input terminal. The comparator outputs a comparison result signal to an output terminal. This output signal is fed back to the non-inverting input terminal via a feedback element so that the potential at the non-inverting input terminal changes with the output signal of the comparator. With the operation of the potential control circuit, a large feedback signal of the feedback element is used when a tracking control off signal is supplied, so that the potential at the non-inverting input terminal is easy to change with the output signal level. When the tracking control off signal is not supplied, a small feedback signal is used to change the potential at the non-inverting input terminal with the output signal level. The signal detected by the comparator is supplied to the output circuit to reference the direction control signal and generate a track traverse detecting signal.

A high-density recording medium has data tracks and guide tracks formed on both sides of each of the data tracks. Intervals between the guide tracks are set in such a manner that the outer edges of two adjacent guide tracks correspond in position to two tracking laser beam spots on the recording medium. To allow use of either of the high-density recording medium, and a conventional recording medium on which intervals between guide tracks are set in such a manner that the inner edges of two adjacent guide tracks correspond in position to two tracking laser beam spots, control is performed such that polarity of a tracking control servo is selectively inverted depending upon which of the high-density and conventional recording medium is used.

A position detector detects a relative position of an optical head to a recording medium, and on the basis of the thus-detected relative position, a position detection signal is generated in response to movement of a light beam over a predetermined distance. Then, in response to the position detection signal, a comparison is made between the number of track crossing counted for the predetermined movement distance on the basis of reception of reflection of the light beam, and a predetermined reference value for the predetermined movement distance. Then, track crossing count compensation data is generated which corresponds to a difference between the counted number of track crossing and the reference value, and the counted number of track crossing is corrected by use of such compensation data.

Information is recorded and reproduced by making a light beam traverse guide tracks to reach a target track. In moving the light beam to the target track, a current output circuit responds to a track jump command, and supplies a drive current to an objective lens driver. The driver current is transformed by the conversion circuit into a rapidly rising and gradually falling current, and supplied to the driver, The objective lens then moves. When the light beam reaches a track adjacent the target track, a track traverse detecting circuit supplies a track traverse detecting signal. In response to this signal, the current output circuit supplies a damping current by reversing the polarity of the drive current to the driver. The damping current is transformed by the conversion circuit into a rapidly rising and gradually falling current, and supplied to the driver.
摘要:
A peak detection circuit accurately detects peaks even if a noise component is included in the input signal. The peak detection circuit includes: a differentiating circuit which produces a differentiated signal of an input signal, a peak hold circuit which produces a peak value envelope of an output of said differentiating circuit, and a first comparator which compares an output of said differentiating circuit and a reference signal formed on the basis of an output of said peak hold circuit, and which detects when said input signal falls below said reference signal A second comparator detects a portion which exceeds an output of said differentiating circuit A flip-flop produces a signal which rises in accordance with an output of said second comparator and falls in accordance with an output of said first comparator, thereby to form a signal representing a peak by the rise of an output of said flip-flop.
