Title: Method of manufacturing electrostatic chuck
Inventor: ASO YUJI
IPC: H02N13/00
Filed: 2003-02-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method by which an electrostatic chuck can be manufactured inexpensively, because, when the electrostatic chuck is formed by a method, in which a projection in contact with an object to be sucked and composed of an insulator is formed by the gaseous deposition method after an insulating film is formed on a conductor substrate by the gas deposition method, both an insulating film and the projection composed of the insulator are formed by the gaseous deposition method only and, accordingly, the volumes (areas and thicknesses) of the film and projection increase and film formation takes time, resulting in the cost increase.  <P>SOLUTION: In this method, the projection 3 in contact with the object to be sucked and composed of the insulator is formed on the surface of a dielectric by the gaseous deposition method after the insulating film 4 is formed by anodizing on the surface of a plate-shaped base material constituted of aluminum or an aluminum alloy. Since the gaseous deposition method is only used at the time of forming the projection 3 composed of the insulator, the film forming cost by the gaseous deposition method can be reduced significantly and, consequently, an inexpensive electrostatic chuck can be provided.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

IPC: H01M10/42
Filed: 2003-03-12
Abstract: <P>PROBLEM TO BE SOLVED: To shorten total charging time by simple algorithm.  <P>SOLUTION: A microcomputer 22 prepares the charging pulses Dc of an identical pulse waveform and the discharging pulses Dc of the identical pulse waveform. With inner impedance Z of a secondary cell 1 connected, their change is reflected in the period P of charging pulses Ch. When the charging pulse period P exceeds a changeover set point PI, a switch SW 25 is closed by the charging pulses Ch to supply a charging current Ic to the cell 1 for charging. Subsequently, a discharging circuit 24 is conducted by the discharging pulse Dc to make the cell 1 discharged by a discharging current -i, and the period of the supplies of the charging pulses Ch is shorted to increase the number of the supplies. By properly selecting and determining discharging capacity by the discharging pulses Dc in this process, the total charging time can be shortened. The changeover set point PI and a charge-finishing set point Pc are used as the charging pulse period, but other instrumentation elements such as a measured voltage value of the cell, for example, may be used.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Filed: 2003-03-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method of transmitting traveling track data, which can precisely transmit a traveling track with minimized data volume in a probe car system.  <P>SOLUTION: An FCD on-vehicle machine re-samples a traveling route of traveling with measuring a position in a re-sampling section length set in conformation to the radius of curvature range of a road, represents the position information of a sampling point by a parameter having a statistical deviation, encodes the value of the parameter in variable length, and transmits it to an FCD collection device. The FCD collection device decodes the received data to reproduce the position information of the sampling point, and specifies the traveling route by map matching using the position information. The encoding enables the significant reduction in data volume of the traveling track. Since the interval of sampling points is set short when a probe car travels in a sharply curved road, the traveling track can be precisely grasped at a center.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
