Abstract: PROBLEM TO BE SOLVED: To efficiently perform multicarrier transmission in a state the noise periodically changes. SOLUTION: On the side of a central station (XTU-C), the tone of a tone generating part 21 is transmitted while controlling its level by a clock synchronized with the noise. A clock cycle is detected by a clock detecting part 33 on the side of a terminal (XTU-R). A pseudo random signal (containing all carriers) is transmitted from a pseudo random signal generating part 20 on the side of the central station, and the SNR of the carrier is measured for each detected clock cycle (noise cycle) by an SNR measuring part 34 on the terminal side. According to this measured result, the power/bit distribution of each carrier is calculated by a power/bit distribution calculating part 35, this is stored as information for demapping during a down carrier transmission, and this is transmitted to the central station side as well and stored in a mapping part 12 on the central station side. Thus, the down transmission is performed. It is similar concerning up transmission as well.

Title: Bonding strip and bonding method using the same
Inventor: MISTRY MAHESHCHANDR
IPC: H01L21/52
Filed: 2002-07-12
Abstract: PROBLEM TO BE SOLVED: To provide a bonding strip and a bonding method using a strip, which enables efficient temperature rise and facilitates surer temperature control. SOLUTION: A die-bonding strip 50 is made of titanium alloy and the thickness of the cross-section in its center region 70 is smaller than the thickness of the cross-section at the end region 56. The electrical resistance at the center region 70 is increased by the cross-sectional shape, and the temperature rise caused by the supplied power is increased. As heat applied to the strip 50 is concentrated to the center region 70 and not distributed over the whole strip, the efficiency of the strip is improved. Only one thermocouple 60 is used for the temperature management and fixed to the strip 50 by spot welding. With such a constitution, a system structure can be simplified and the surer temperature control can be practiced.
