In a heat sink, a portable electronic apparatus using this heat sink, and a method for forming this heat sink, an abutting member is arranged on an inside surface of a casing and the casing and the abutting member are covered with a heat spreader sheet. The heat spreader sheet is made to abut against an exothermic device by means of an abutting member. The heat generated in the exothermic device is transmitted to the inside wall surface of the casing via the heat spreader sheet, with a portion being transmitted via the abutting member. When an anisotropic thermal conductivity material is used for the abutting member, it is possible to realize characteristics such as a low peak casing temperature under the exothermic device.

A sample stage device (10) is so configured as to calculate ideal position information xtg(i), tg(i) per predetermined period that is unaffected by drive conditions relating to gaps (25, 26), etc., and to determine, per predetermined cycle and in real time, deviations dx(i), dy(i) between real-time measured positions x(i), y(i) by position detectors comprising laser interferometers (33, 34), etc., and ideal position information xtg(i), tg(i). In addition, it calculates, based on deviations dx(i), dy(i) thus determined, such speed command values vx(i), vy(i) for motors (27, 28) that measured values x(i), y(i) would follow ideal position information xtg(i), tg(i), and performs stable and high-speed positioning control for a sample table (11) through feedback control that controls speed in real time. Thus, with respect to a sample stage device, it is possible to provide a stable and high-speed positioning control method for a sample table, which is capable of suppressing noise caused by thermal drift and vibration, without being affected by drive conditions, such as the initial states of gaps, etc.
