IPC: H04L1/00
Filed: 2000-11-14
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption or the like by stably controlling transmitting power while exactly following the change of a radio wave environment or the like. SOLUTION: A baseband part 6 as a frame error rate(FER) extracting means extracts FER information, which is contained in each of frames of a radio signal received by a radio part 4, related to the transmitting signal of the radio part 4 in a fixed cycle and each time the baseband part 6 extracts the FER information, an FER calculating means 20 calculates the evaluation value of FER by multiplying and adding a weight to each of FER expressed by the FER information of a closest first number continuously extracted by the baseband part 6.  Then, a transmitting power control means 22 compares the evaluation value calculated by the FER calculating means 20 with a reference value and when the evaluation value is smaller than the reference value, transmitting power is decreased by controlling the radio part 4 through the baseband part 6 but when the evaluation value is greater than the reference value, the transmitting power of the radio part 4 is increased.

Title: Piston of internal combustion engine
Inventor: SHIRABE TAKEO
IPC: F02F3/22
Filed: 2000-11-21
Abstract: PROBLEM TO BE SOLVED: To provide a piston of an internal combustion engine capable of preventing damage of the top wall surface of the piston and the piston ring caused by the pressure inside a combustion chamber while reducing the weight. SOLUTION: The piston has a groove 7 extending along the whole circumference of the piston on the outer peripheral region of the piston top wall surface 2 which forms the combustion chamber of the internal combustion engine. The pressure heightened by fuel combustion is propagated around toward the inner wall surface of a cylinder from the combustion point. However, the pressure isn't evenly propagated from the center of the piston 1 toward the circumference, and therefore, there are regions where the pressure is high and where the pressure is low inside the combustion chamber, and especially in the peripheral region of the combustion chamber. In the piston, the extremely high pressure is propagated along the groove 7 to the region where the pressure is relatively low.  Therefore, since there is no region where the pressure is high in the piston, damages on the top wall surface 2 of the piston 1 or the piston ring 4 can be prevented.
