In a PC card communication terminal that operates supplied with power from a host device, problems such as malfunctions due to a supply voltage drop at the time of high transmission output are prevented from occurring. A baseband processor (1106) selects a transmission-power upper-limit measurement mode when a PC card terminal (1103) is to be controlled for the first time. A supply voltage drop is measured by a voltage measurement circuit (1114) while a load value of a load circuit (1112) is being changed. The load value of the load circuit (1112) when the supply voltage decreases to a permissible lowest supply voltage is obtained. Using a conversion table stored in a memory (1107), the load value is converted into a transmission output and is set as a transmission-output upper limit. In a normal communication mode, a maximum transmission output is restricted based on this transmission-output upper limit.

Reference light is incident to a Michelson interferometer, in which is obtained a reference interference electric signal which undergoes a sinusoidal variation in accordance with interference of reference light as a movable reflector (14) moves. A direction control signal indicating the direction in which to move the movable reflector (14) is applied from a control circuit (21) to a two-phase signal generator (32B), which derives, from the reference interference electric signal, two-phase signals either one of which leads the other by a phase angle of 90.degree. in accordance with the specified direction. The two-phase signals are fed back to a servo drive circuit (19) and a movement control signal is also applied from the control circuit (21) to the servo drive circuit (19) to control the movement of the movable reflector (14). Thus, the movement of the movable reflector can be controlled with a high degree of accuracy corresponding to the accuracy of the wavelength resolution of the reference light.

An alignment system usable in a semiconductor device manufacturing apparatus of step-and-repeat type for superposingly printing a pattern of a reticle onto each of patterns on a semiconductor wafer in a step-and-repeat manner. The alignment system is adapted to align each of the patterns of the wafer with respect to the pattern of the reticle, prior to exposure for printing the pattern, by use of alignment marks provided for each pattern of the wafer. In this alignment system, if the alignment marks for a particular pattern on the wafer are damaged or wiped off by the chemical or thermal treatment of the wafer, the alignment of the particular pattern of the wafer with respect to the pattern of the reticle is achieved on the basis of positional information detected from another alignment mark provided for another pattern of the wafer adjacent to or in the neighborhood of the particular pattern of the wafer, whereby the pattern of the reticle can be accurately overlaid on the particular pattern of the wafer.
