Abstract

PURPOSE:To lessen the error in measurement of reflected electric waves using a float type specimen supporting device by controlling attitude control devices arranged around a device for putting the specimen afloat in conformity to signals given by specimen attitude sensors. CONSTITUTION:A specimen 5 is put afloat in a space by the magnetic force generated from a coil for holding the specimen afloat 1, and the attitude, etc., of the specimen is sensed by a plurality of specimen attitude sensors 3, and signals therefrom are fed to a control device 4. This control device 4 calculates the attitude and position of the specimen 5 on the basis of the signals from sensing and controls the currents in a plurality of attitude control coils 2 arranged around the first named coil 1 so as to hold the attitude of the specimen 5 constant. The control device 4 varies continuously the attitude of the specimen 5 in conformity to a command signal given externally. This eliminate reflection of unnecessary electric waves from this supporting device concerned entirely, which provides high precision measurability for the reflected electric wave.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a floating specimen support device used for measuring radio wave reflection.

[Conventional technology]

In conventional radio wave reflection measurements, as shown in FIG. 2, the specimen 5 is supported by a support base 6 made of a low radio wave reflection material or a low radio wave reflection shape.

[Problem to be solved by the invention]

In conventional measurements of radio wave reflection, even if a specimen support made of a material or shape with low radio wave reflection is used, unnecessary radio wave reflection still exists, resulting in measurement errors.

The present invention aims to solve the above problems and provide a device that can eliminate unnecessary radio wave reflections.

[Means to solve the problem]

The specimen support device of the present invention includes a levitation device on which a specimen is mounted, an attitude control device disposed around the levitation device, and a posture control device that receives signals from a specimen attitude sensor. The invention is characterized in that it is equipped with a control device that outputs a control signal to.

[Effect]

In the above, the specimen is levitated in space by the action of magnetism or air by a flotation device. The attitude of the levitated specimen is detected by the specimen attitude sensor, the signal is input to the control device, the control device sends a control signal to the attitude control device, and the attitude control device uses magnetic or air The posture of the specimen is controlled by the action.

As a result of the above, the specimen can be floated above the support device, so there is no reflection of unnecessary radio waves from the support device, the measurement error of radio waves is small, and high precision measurement of reflected radio waves is possible. [Embodiment] An embodiment of the present invention is shown in FIG.

In this embodiment shown in FIG. 1, a levitation coil 1 on which a specimen 5 is mounted, a plurality of attitude control coils 3 arranged around the levitation coil, and a signal from a specimen attitude sensor 3 are used. The control device 4 inputs the current and controls the current supplied to the attitude control coil 3.

In the above, the specimen 5 is levitated in space by the magnetic force of the levitation coil 1. The levitated specimen is detected by the specimen attitude sensor 3.
detects the posture of the specimen 5, the control device 4 inputs the signal, calculates the posture 2 position of the specimen, and controls the current of the posture control coil 2 to change the posture of the specimen 5. Keep it. It is also possible to send a command signal to the control device 4 from the outside to continuously change the attitude of the specimen 1.

Note that similar operations and effects can be obtained by using an air-based device to control the levitation and posture of the specimen I.

As a result of the above, the specimen can be levitated on the support device, so there is no reflection of unnecessary radio waves from the support device, the measurement error of reflected radio waves is reduced, and highly accurate measurement of reflected radio waves is possible.

〔Effect of the invention〕

The floating specimen support device of the present invention controls the attitude by inputting signals from a levitation device on which a specimen is mounted, a posture control device disposed around the levitation device, and a specimen posture sensor. By having a control device that outputs control signals to the support device, the specimen can be levitated above the support device, which eliminates the reflection of unnecessary radio waves from the support device and reduces measurement errors in reflected radio waves. , high precision measurement of reflected radio waves becomes possible.
