  • Patent number: 8349127
    Abstract: A wafer stage includes a first evaporator where a refrigerant circulates. The first evaporator makes up a cooling cycle with a compressor, first condenser, expansion valve, second evaporator, refrigerant thermometer, and refrigerant flowmeter. The first condenser is supplied with a heat exchange medium. The temperature of a coolant supplied to the second evaporator is measured by an inlet refrigerant thermometer and outlet refrigerant thermometer, while the flow rate of the coolant is monitored and adjusted by a flow-rate adjuster. The temperature difference in the coolant between being at the inlet and at the outlet and flow rate can be measured. Upon complete evaporation of the refrigerant in the second evaporator, the dryness of the refrigerant discharged from the wafer stage is calculated from the amount of heat absorbed from (exchanged with) the coolant, the circulation amount of the refrigerant and the refrigerant temperature to control the rotational speed of the compressor.

  • Patent number: 8353060
    Abstract: It is difficult for a scanning probe microscope according to the conventional technology to operate a probe for scanning and positioning in a wide range and for high-precision scanning in a narrow range. A scanning probe microscope according to the invention uses probe driving actuators for coarse adjustment and fine adjustment. For scanning and positioning in a wide range, the coarse adjustment actuator is switched to fast responsiveness. For scanning in a narrow range, the coarse adjustment actuator is switched to slow responsiveness. Instead, positional noise is reduced and the fine adjustment actuator is mainly used for scanning in a narrow range. The probe is capable of not only scanning and positioning in a wide range but also high-precision scanning in a narrow range.

  • Patent number: 8350615
    Abstract: If a power supply is provided to a circuit necessary to control a switch for switching a path after wakeup, or if a buckle switch is switched while a microcomputer is asleep, an electrical current necessary for reliable operation of the buckle switch cannot be supplied during sleep, so that the buckle switch will not operate normally. This creates the possibility that wakeup cannot be performed. To permit the electrical current necessary for reliable operation of the buckle switch to be secured if the buckle switch is switched while the microcomputer is asleep, an FET capable of being kept ON or OFF by a power supply acting during sleep, a resistor connected with the FET, and a resistor of large resistance for blocking excessive dark current if the buckle switch is connected are arranged in parallel. The combined resistance of the parallel combination of these elements is used as a pull-up resistance at the input of a control unit.
