Title: Device for holding sample of veriable temperature
Inventor: KOYANAGI KAZUO
IPC: H01J37/20
Filed: 1985-02-28
Abstract: PURPOSE:To aim at shortening the time required for cooling or heating samples by using materials with different thermal expansion coefficients by choice for a sample holder as well as a sample stand, so that the engagement between the stand and the holder at a normal temperature can be slackened and inserting or taking out of the holder can be made easier, thereby obtaining better thermal connection at a given temperature. CONSTITUTION:The state of engagement between a dovetail groove 6 of a sample stand 3 and the under surface of a sample holder 2 is such that at a normal temperature, a projecting part of the under surface of a sample holder 2 is smaller than a section of a dovetail groove 6, thus having a gap between the both. A material of the stand 3 is selected out so as to have a bigger thermal expansion coefficient that the one of the holder 2, and when the holder 2 is inserted into the dovetail groove 6 at a normal temperature and then a cold medium is passed through a space 4, as the temperature comes down lower, the stand 3 gets shrunk much more than the holder 2, causing the projecting part of the under surface of the holder 2 to be sandwitched under pressure by surfaces of both sides of the dovetail groove 6 and further, forcing the under surface of the holder 2 to be pressed down on to the bottom surface of the dovetail groove 6 by its inclined planes, so that the projecting part can get in contact with the stand 3 under strong contact pressure at its three surfaces, thus enabling to obtain better heat conductivity. As a result, the time required for the sample 1 to reach a given temperature can be reduced accordingly.

Filed: 1981-03-19
Abstract: PURPOSE:To provide a titled device of high reliability with simple constitution by starting stopping-down by starting a motor, stopping the motor until the aperture is determined temporarily and restarting the motor after prescribed delay. CONSTITUTION:When a release switch SW1 is turned on, a motor 1 starts revolving counterclockwise, and a shaft 6 revolves clockwise, then a cam face 8a decreases a lift gradually with respect to a pin 9, thereby giving a min. aperture diameter to a lens 17. When the cam 8 arrives at the start end of a min. lift area, the revolution of the motor 1 is stopped to wait until the aperture value determining operation ends. Namely, a revolution stop signal Sig-1 is generated by detecting that a hole 27b provided to the 2nd gear 27 and a sensor 28b faces each other, and this signal is fed to a circuit C1. As a result, the electric brake is applied to the motor 1, and the shafts 6, 29 stop. When the signal Sig-1 is fed, a timer circuit C3 starts and a restart signal sig-2 is generated, in accordance with which the motor 1 starts revolving again in the arrow direction.
