Filed: 1984-06-15
Abstract: PURPOSE:To enable focusing and the correction of astigmatism to be performed automatically by detecting the direction of astigmatism and the amount of astigmatic difference while performing circular scanning. CONSTITUTION:Electron rays are scanned over a sample surface 5 in circular form. A signal for secondary electrons produced from the sample is used as the input to a signal-treating circuit 17. The signal-treating circuit 17 delivers a signal which is then stored in one of the contents (R1-Rn) of a memory 12 according to the rotation angle (beta) of circular scanning. The voltage of this signal increases for a decreased diameter of the electron beam. The contents (R1-Rn) are transferred to the memories (M1-Mn) of a memory group 13. This circular scanning is performed for n times by successively increasing the excitation current (If) of the electron lens by DELTAI and the results are stored in the memories of the memory group 13. The direction (alpha) of astigmatism and the positions of the focal point on the U and the V axes are obtained from the number (Ms) of the memory.

Title: Water-temperature measuring device
Inventor: MINOHARA KIYOMI
IPC: G01K11/22
Filed: 1983-07-04
Abstract: PURPOSE:To make it possible to measure water temperature continuously and to perform the measurement of the water temperature in a broad range in a short time, by providing ultrasonic-wave transmitting and receiving devices at specified positions on the bottom of a ship, and measuring the states of the transmitted and received waves. CONSTITUTION:Ultrasonic waves f0 are continuously transmitted from the bottom of a navigating ship at a depression angle beta. The ultrasonic waves f0 are reflected by the sea bottom M and received by receiving devices 3A, 3B and 3C, respectively. However, the distribution of the sound speeds is not uniform, and the speed increases in proportion to the depth of water. Therefore, the sound speeds do not become constant. The propagating path of the sound wave is continuously refracted. In general, in a dopple sonar, the depression angle of the transmitted ultrasonic wave is sufficiently large so that total reflection is not yielded at an interface. Therefore, the sound wave is refracted downward primarily owing to the temperature gradient, reflected by the sea bottom, and returned. Thus, the continuous measurement of the water temperature can be performed. Since this operation is continuously performed, the measurement of the water temperature in a broad range can be performed in a short time.
