摘要： Disclosed herein is an electronic apparatus produced using a high-temperature lead-free solder alloy which makes it possible to form soldered joints having no variations in strength and which has an excellent balance between strength and solderability. The lead-free solder alloy is an alloy which is made of an element A and an element B and which has a composition composed of AmBn being a stable phase and the element B in an equilibrium state at room temperature. When the lead-free solder alloy is solidified by quenching, the element A is dissolved in a room-temperature stable phase of the element B so that a supersaturated solid solution is formed, and when melted for soldering and then solidified, the alloy returns to its equilibrium state and has a composition composed of the stable phase AmBn and the element B and therefore maintains strength due to the presence of the stable phase AmBn even when reheated to a soldering temperature.

摘要： When a signal of weak optical power is received immediately after a signal of intense optical power, input of the signal of intense optical power readily causes saturation, and the influence interferes in the signal of weak optical power to deteriorate receiver sensitivity. Moreover, when a reverse-bias voltage of APD is changed, if a difference between the voltages is large, a next optical signal is received until the receiver sensitivity of the APD becomes stable, so that receiver sensitivity deteriorates. A DBA order is determined so that a difference in reverse-bias voltage is small, and reverse-bias voltage is controlled in line with reception timing from ONU.

摘要： Channel switching system and method of an IPTV service in a passive optical network (PON) are disclosed. To reduce a channel switching time of an IPTV system in the passive optical network, the system and the method use a channel switching control module and a channel list module in the passive optical network. In a case where a passive optical network system receives an IPTV channel switching request transmitted from a terminal user, the channel switching control module checks a recording of a channel list module and a recording of an authentication list module, and then updates a filter recording of an optical network unit to thereby directly transmit an image flow of a new channel in the passive optical network. When such system and method are applied to the passive optical network, high-speed switching of the IPTV service channel by the terminal user can be realized.

摘要： When the number of DUTs carried on a loader buffer and scheduled to be held by contact arms at the next test is less than N, a DUT at a contact arm corresponding to a missing position at the loader buffer among the N number of DUTs being held for execution of a current test is held as it is without being ejected. While holding this DUT, the DUTs carried at the loader buffer for execution of the next test are picked up and the test is executed in that state.

摘要： An IP broadcast terminal 30 is connected with a multicast address management device 10 for IP broadcast that holds multicast information via an IP multicast network 40 over which IP broadcast service is provided, and when a user issues a request to change an IP broadcast channel, generates a query message including an IP broadcast channel identifier requested from the IP broadcast terminal 30 to transmits it to the multicast address management device 10 for IP broadcast. The IP broadcast terminal 30 receives a response message showing the correspondence between IP broadcast channel identifiers and multicast addresses from the multicast address management device 10 for IP broadcast, and transmits a video reception request message to a multicast group decided for reception.
