摘要： In an optical data recording and reproducing apparatus comprising an information signal generator, a sample/hold switching signal generator, a write/read switching signal generator, a laser beam source, a reference voltage generator, a comparator and a photo detector, a dummy signal is added to the information signal modulating the laser beam or generation of the laser beam is forcedly stopped after a data write servo mode so as to prevent generation of the laser beam of an excessively high level at the time of change-over from the data write servo mode to a data write hold mode or from the data write hold mode to a data read mode, or the level of the write/read switching signal is changed before the level of the sample/hold switching signal is changed at the time of change-over from the data write hold mode to the data read mode, or the duration of emission of the laser beam is extended slightly before the level of the sample/hold switching signal is changed.

摘要： A multicast packet readout control method is disclosed. An input multicast packet is temporarily stored in a multicast queue of a packet buffer. The multicast packet is read from the multicast queue, and converted into a unicast packet addressed to each of the destinations of the multicast packet. The converted unicast packet is stored in a unicast queue of the packet buffer. The converted unicast packet is then read from the unicast queue and transmitted to the destination.

摘要： A semiconductor laser drive circuit functioning as a light source of an optical recording/reproducing apparatus using an optical disk. In the recording mode, the input light of a semiconductor laser is modulated by a recording signal, the output light of the semiconductor laser is detected as a monitor signal by a photo sensitive device, the peak value of this monitor signal is held by a peak-hold circuit, a differential compensation control signal is obtained from the output of the peak-hold circuit and is fed back, and a photo control system to control the output light to a constant level is constituted, thereby controlling in such a way that the output light of the semiconductor laser becomes a certain constant modulation amplitude. Even upon recording, the output light can be stably controlled within a wide temperature range even if the characteristic of the semiconductor laser changes with the elapse of time. Also, this drive circuit can be realized by a simple arrangement.

摘要： In an ATM cell multiplexer which multiplexes ATM cells outputted from a plurality of cards, sequential cell arrival numbers common to the ATM cells outputted from a plurality of cards are added to each of the cells to be written in memories, and the read side checks a sequentiality of the cell arrival numbers whereby the ATM cells are read in the order of arrival and the cell arrival number at that time is used as the cell arrival number to be checked at the next read time. Also, when any of the cards is pulled out, a card not pulled out is operated normally and an address counter of only the pulled-out card is cleared. Even when non-sequentiality of the cell arrival numbers occurs due to the clearance of the address counter, the maximum cell arrival number is set to the value which enables the oldest cells to be read first. Furthermore, by the division of storing memories according to priority degrees, a read control identifying the ATM cells for a real time system as well as the ATM cells for a data system can be performed.

摘要： A drive circuit drives a liquid crystal display device of the type in which liquid crystal fills a space between an X-Y matrix substrate having a number of picture elements each including a switching element, and a common electrode plate. The drive circuit provides an optimum picture displayed to an observer in accordance with ambient conditions such as light and temperature. To this end, a DC bias voltage to determine the operating point of the liquid crystal display device is applied to the common electrode. The brightness of the displayed picture may be controlled by adjusting the DC bias voltage. The DC bias is changed in accordance with a change in an amount of ambient light or ambient temperature. Furthermore, in accordance with the fall of the ambient temperature the DC voltage applied to the common electrode is made to oscillate at a frequency to which the liquid crystal is insensitive, with respect to the bias point. At this time, the amplitude of the oscillation is made large.

摘要： In a packet transmission method and device, when a received packet is written in a packet buffer, an address of the packet buffer is stored as a read address for each destination corresponding to a physical port and storing information of the received packet. The read address of a destination designated by the received packet information is read and saved when the received packet is read out of the packet buffer in accordance with a scheduling control. Then, the saved read address is taken out in accordance with an arbitration control and a received packet corresponding to the saved read address is read from the packet buffer.
