Title: Device for estimating weight of vehicle
Inventor: YAMADA NAOKI
IPC: G01G19/08
Filed: 2001-05-21
Abstract: PROBLEM TO BE SOLVED: To precisely estimate the weight of a vehicle. SOLUTION: A microcomputer filter-processes driving force Fhat of the vehicle estimated based on a speed ratio by an estimated driving force calculating part 100 and a driving force signal filter-processing part 200, finds a driving force hf after filtering, and integrates the absolute value of the driving force hf after filtering by an area comparing part 600 to obtain a driving force integrated value SF. By the same manner, an acceleration dv found by a rotational speed of an output shaft is filter-processed by an acceleration calculating part 300 and an acceleration signal filter-processing part 400 to find an acceleration hdv after filtering, and the absolute value of the acceleration hdv after filtering is integrated by the area comparing part 600 to obtain an acceleration integrated value Sa.  The area comparing part 600 estimates the weight of the vehicle m by dividing the driving force integrated value SF by the acceleration integrated value Sa.

Title: Waxless mount polishing method and device thereof
Inventor: KOMATSU KEI
IPC: B24B37/30
Filed: 2001-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a waxless mount polishing method preventing the outer periphery erected on a semiconductor wafer. SOLUTION: At the time of polishing, a silicon wafer W is housed in a template 14 and the silicon wafer W is sucked on a suction pad 15 by the surface tension of water. At the time, a wafer outer periphery is projected more outward than the center part. While keeping the state, a polishing head 12 is rotated, while supplying an abrasive onto a polishing cloth 13 and the surface of the silicon wafer W is pressed to the polishing surface of the polishing cloth 13 and polished. As a result, for the outer periphery of the silicon wafer W, a contact area per unit time with the polishing cloth 13 and pressure per unit area become large as compared with the center part. Thus, the outer periphery erection of the silicon wafer W is prevented.
