| 20100089498 | Lead-Free Jointing Material and Method of Producing the Same - The present invention provides a high-temperature lead-free solder alloy which has no variation in strength of the soldered portion and has an excellent balance between strength and soldering properties, and a method for producing the alloy. The present invention relates to a lead-free jointing material made of an alloy of two elements A and B selected from elements other than Pb, wherein the element A has a melting point higher than a melting point of the element B, wherein the alloy is an alloy which has a room-temperature stable phase composed of the element B and a room-temperature stable phase A | 04-15-2010 |
| 20100246148 | Electronic Apparatus Produced using lead-Free bonding Material for Soldering - 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. | 09-30-2010 |

| 20090058439 | ELECTRONIC DEVICE TEST SYSTEM - 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. | 03-05-2009 |
| 20100239155 | ABNORMALITY DETECTING APPARATUS FOR DETECTING ABNORMALITY AT INTERFACE PORTION OF CONTACT ARM - An abnormality detecting apparatus includes an imaging device for obtaining image data of a TIM, a failure detecting section for detecting appearance failures of the TIM on the basis of the image data of the TIM obtained by the imaging device, and a determining device for determining whether an abnormality occurs at the TIM on the basis of a detection result by the failure detecting section. | 09-23-2010 |

| 20090162063 | NETWORK SYSTEM, OPTICAL NETWORK UNIT AND OPTICAL LINE TERMINAL - It is necessary to completely remove overlapping of signals between plural PONs in order to make the PONs coexist. Accordingly, it is required to share or intensively manage bandwidth use conditions over an optical fiber that serves as a common band between plural systems. Therefore, transmission clocks should be synchronized with high accuracy between plural systems. A reference clock is provided from an external device or a representative OLT to the entire systems to perform clock synchronization between plural systems, so that the overall systems are synchronized by synchronizing each OLT with the reference clock. A hierarchical management method is selected that manages ONUs under the control of each OLT by managing band use information arranged for each OLT with respect to an external device or a representative OLT for sharing of bandwidth use conditions between plural systems. | 06-25-2009 |
