Title: Automatic correction circuit of burst signal time
Inventor: OOTA HIROMI
IPC: H04J3/06
Filed: 1983-11-07
Abstract: PURPOSE:To avoid error produced by a manual adjustment and to facilitate easy handling of a correction circuit for time difference of burst signal, by correcting automatically the time difference between two signals. CONSTITUTION:A burst signal generating gate 1 intermits (n) units of pseudo pulses 8b given from a pseudo pulse generator 8 at the transmission side of an automatic correction circuit by means of a burst signal 9a given from a burst signal generator 9. Then the intermitted pulse is aplied to a device 5 to be measured in the form of a burst pulse signal 1a, and a burst pulse a is applied to a pseudo pulse detector 2 of the reception side from the device 5 with a prescribed time delay. Thus the synchronization is secured, and an error pulse signal 2b and a reception frame signal 2a are applied to an inhibition circuit 6 and a time difference detector 3 respectively in accordance with the presence or absence of a code error. Then a time difference count pulse signal 3a given from the detector 3 and the signal 9a of the generator 9 are applied to a time difference corrector 4. A corrected burst signal 4a is applied to the circuit 6. Thus the time signal between both signals is automatically corrected. This avoids an error which is caused by a manual adjustment.

Abstract: PURPOSE:To enable stepless, continuous, and easy adjustment of a set load, by adjusting the set load of the spring in a shock absorber by means of the hydraulic force of an oil pressure generating device mounted separatedly from the shock absorber. CONSTITUTION:When a regulating screw 35 is turned through control of a regulating dial 36 of an oil pressure generating device 30 to move upward a piston 32 into which a regulating screw 35 is screwed, the interior of an oil pressure chamber S2 is increased in an oil pressure. The oil pressure is propagated to an oil pressure chamber S1 of an adjuster unit 20 through a pipe 38, and is exerted on the upper surface of a piston 22 to move downward a spring support 9 togetherwith the piston 22 and a piston rod 23. As a result, a coil spring 12 stretched between the spring support 9 and a sheet pipe 4 is reduced in a set length, and the set load of the spring 12 is regulated to a high value. Reverse turning of the regulating dial 36 causes upward movement of the spring support 9, and the set load of the spring 12 is adjusted to a low value.

Title: Electron microscope observation system
Inventor: IWATA TSUNEKAZU
IPC: H01J37/22
Filed: 1995-08-18
Abstract: PROBLEM TO BE SOLVED: To construct an environment just like a person who requests analysis feels as if staying near an electron microscope by transferring a magnified image of the electron microscope via a transmission path to the person in a remote site. SOLUTION: An image of a sample output by an electron microscope main body 1 is converted by a converter 2 and an A/D converter 3 into a signal for transfer, which is then transmitted to a transmission path 4. A D/A converter 5 converts the signal from the transmission path 4 into an analog signal for display on an image display device 6. In the case of a scanning electron microscope, the converter 2 converts the image with a frame speed of 30 to 90 per second corresponding to the scanning speed characteristic of the microscope into a standard video signal. The transmission path 4 utilizes an ISDN circuit or other networks convenient for transfer of image information.  A person who requests analysis observes the magnified image of the sample and shows photographic requirements, such as portions of the sample, a desired magnification, to the operator of the electron microscope main body 1. Alternatively, using a scanning signal input device 7 the person directly operates the electron microscope main body 1 via an electron microscope operating device 8.
