Abstract: PROBLEM TO BE SOLVED: To provide an effective method of mounting for realizing a fluxless bonding in the air, when mounting an IC chip having solder bumps formed of lead-free solder on a wiring board by a flip chip bonding method. SOLUTION: The surface of a lead-free tin-zinc-based solder alloy of which the solder bumps 12 of the IC chip 11 are formed is reformed, The purpose of this reformation is to prevent reoxidation of tin and zinc by removing a tin oxide film and a zinc oxide film on the surface of the solder bumps 12 by casting a hydrogen-contained plasma 13 and then forming a fluorine-contained layer on the surface of the solder bumps 12 by casting a fluorine-contained plasma, After the reformation, the solder bumps 12 of the IC chip 11 are directly mounted on metal electrodes of the wiring board and then are bonded by a flip chip bonding method, By reforming the oxide film layer of the solder bumps 12 formed of a tin-zinc-based solder alloy, a fluxless bonding of the solder bumps 12 of the IC chip 11 and the metal electrodes of the wiring board, is made possible in the air.

Abstract: A building monitoring and control system is disclosed that includes a bi-directional radio link between master and remote units, wherein the remote units adjust transmission power to a level adequate for communication but not so high as to waste power and unnecessarily decrease battery life. In one embodiment, the master unit measures a received signal strength from the remote units and uses that measure to provide feedback to the remote units as to whether their transmissions are too strong, too weak, or within an acceptable range. In another embodiment, the remote units receive an analog measure of the master unit received signal strength and use that measure as an indication of whether to increase or decrease the transmission strength. In yet another embodiment, the lack of an acknowledgement from the master is used as an indication that the remote signal is not strong enough.

Abstract: <P>PROBLEM TO BE SOLVED: To prevent an increase in switching loss even when the temperature of a semiconductor chip rises, though the conventional semiconductor module for electric power comprising an inverter, where a plurality of semiconductor chips for electric power such as IGBTs or FETs are fixed to a copper circuit, has such a demerit that the temperature of the semiconductor chip increases as conductive current increases and switching loss is made large, and furthermore the temperature increases as a result.  <P>SOLUTION: A thermistor is arranged near a semiconductor chip for electric power on a copper circuit, and it is electrically connected with a gate, so that the resistance value of the gate is reduced when the temperature increases. In such a circuit, switching loss can be reduced because the resistance value of the gate is made small even when the temperature increases.  <P>COPYRIGHT: (C)2003,JPO

Abstract: On the basis of the existing mobile radio systems of the so-called second generation, such as the GSM, new mobile radio systems are being developed for the so-called third generation, such as the UMTS, which should be characterized by a higher and flexible transmission rate and should include a package-oriented exchange technology, particularly ATM. In order to create a connection between the different mobile radio systems, a transmission of data between a first mobile services switching center (2GMSC) of a first mobile radio system (2G) and a second mobile services switching center (3GMSC) of a second mobile radio system (3G) is proposed, whereby the mobile services switching centers are connected through an interface (A*), via which useful data is transmitted at a variable useful data transmission rate, in which the useful data is transmitted within data frameworks including a definite pre-determined number of data fields, whereby, depending on the amount of useful data to be transmitted, at least one part of the data fields is first specified with the useful data and then the remaining part of the data fields is specified with dummy bits. In this way, a transmission channel which uses a fixed gross transmission rate (e.g., 64kbit/s), but a variable useful data transmission rate (0-57.6kbit/sec) is created.

Abstract: The present invention is a novel method and apparatus for providing transparent mobility of an entity within a network. The present invention allows a given entity, which has a communication path set up between it and a peer entity, to move from one location to another, without informing the peer entity of this movement, and without having the communication path broken. The present invention is applicable to decentralized networks using the IP protocol, and is particularly applicable on networks wherein it is desired that the mobility mechanism neither introduces latency nor decreases the available bandwidth of the network. In the present invention, neither is latency increased nor is bandwidth utilization increased, as is done in other mobility models. Additionally, the present invention utilizes standard protocols that are widely available from a plurality of equipment manufacturers on a variety of platforms. Thus, the present invention provides a very cost-effective model for network providers that need to support transparent mobility within their network.
