Abstract: PURPOSE:To keep a detection position unchanged even when a treatment is executed at any threshold level by a method wherein an even-order harmonic wave of a pattern- detecting signal is removed and a measuring operation and a positioning operation are executed after signal waves have been made symmetrical with reference to a line. CONSTITUTION:A measuring operation and a positioning operation are executed in such a way that an even-order harmonic wave of a detection signal of a pattern 2 on a wafer, a mask, a reticle or the like is removed and that signal waves are made symmetrical with reference to a line. For example, a signal of the scattered light 1' caught by a detector 5 is amplified to a definite level by using a preamplifier equipped with an AGC; a fundamental wave(f) is extracted by a fundamental wave (f) extraction circuit and is digitized by a digitization circuit 9. From this signal a twofold frequency 2f is generated through a twofold frequency generation circuit 10 and is then converted into a DC voltage corresponding to the frequency by using an F/V converter 11. BEF 7 cuts only the twofold frequency; if an output detected by a synchronous detection circuit 12 is a voltage which is lower than a value set by a comparator 13, an analog SW 14 is turned on; a signal having no second harmonic wave is set to a signal processing circuit 15.

IPC: F28D15/02
Filed: 1986-04-15
Abstract: PURPOSE:To make it possible to easily draw the temperature of a low-temperature body near to that of a high-temperature body to increase a heat transferring efficiency by using a non-azeotropic mixture coolant as a heat medium in the heat transfer device wherein the heat medium sealed in the inner part of a liquid tube and a gas tube absorbs heat and evaporates, then radiates heat to the low-temperature material at a second heat-exchange portion via a gas tube and condenses, and circulates to a first heat exchange portion via a liquid tube thereby to transfer heat of the high-temperature material to the low-temperature material. CONSTITUTION:A non-azeotropic mixture coolant prepared by mixing two or more members of coolants having different boiling points are sealed in a first heat exchange part 10, a second heat exchange part 12, a liquid tube 12 and a gas tube 13. The non-azeotropic mixture coolant absorbs heat from a high temperature fluid H flowing and passing the outside of the tube in the first heat exchange portion 10 and evaporates, entering via the gas tube 13 into the second heat exchange portion 11 wherein the coolant radiates heat to a low- temperature fluid U and condenses, and circulates to the first heat exchange portion 10 via the liquid tube 12. Since the non-azeotropic mixture coolant changes its temperature in the process of evaporation and condensation, the outlet temperature of the low-temperature fluid U can be easily drawn near to the inlet temperature of the high-temperature fluid 14.

Abstract: PROBLEM TO BE SOLVED: To quickly, easily and precisely measure the azimuth and inclination of a stratum by arranging gravity sensors in two axes and geomagnetic sensor in three axes, and arithmetically processing their output electric signals. SOLUTION: Since the partial force of gravity in one axis can be calculated by measuring the magnitudes of partial forces in the other two axes, sensors can be reduced for two axes by omitting the sensor for one axis. The electric signals measured by five sensors in total of gravity sensors 2 and geomagnetic sensors 3 are amplified, converted into digital signals Mx, My, Mz, Gx, Gy by an A/D converter 5, and then inputted to an arithmetic device 6. The device 6 calculates the geomagnetic azimuth θi and inclination ϕi formed with horizontal plane by operation based on the signals Mx, My, Mz, Gx, Gy, and outputs them to a memory device 8. The output control to a display device 9 and the data transfer control to an external input and output device 10 are performed by a control device 7.  The number of the sensors 2 is reduced to two, by which a small-sized device can be economically constituted, and the azimuth θi and the inclination ϕi can be automatically measured at the same time.
