Abstract: PURPOSE:To obtain the microstrip antenna by which a wider radiation directive characteristic is obtained by forming a dielectric plate of a dielectric board and a ground conductor fixed to the dielectric board with a metallic conical truncated member of nearly the same circular shape as that of the radiation conductor. CONSTITUTION:A circular radiation conductor 13 is formed on one side of a dielectric plate 12a of a circular dielectric board 12 and a ground conductor 17 is formed on the other side. The coaxial feeder 16 is penetrated through the dielectric plate 12a from the side of the conductor 17 and the eccentric position 13a of the radiation conductor 13 is energized. The dielectric plate 12a is formed nearly in the same circular shape as that of the radiation conductor 13 and the conductor 17 fixed to the dielectric plate 12a is made of the conical truncated member 15 made of a metal having a plane of nearly the same circular shape as the radiation conductor 13. The microstrip antenna 11 formed in this way has a fringing electric field generated between the radiation conductor 13 and the ground conductor 17 toward a wider area and the radiation directive characteristic on the x-z plane is set wider in the directivity.

Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To hardly receive the influence of light from the outside, to eliminate the influence on an existing system and to prevent the influence from the existing system by performing data communication between a transmitter for modulating a polarization state based on binary data and a receiver for detecting the change of the polarization state. SOLUTION: When transmission binary data 12 are inputted to the input terminal 11a of this transmitter 11, the transmitter 11 emits electromagnetic waves 13 for which the polarization state is modulated based on the transmission binary data 12 into a free space 16 and the electromagnetic waves 13 advance in a (z) axis direction. When the electromagnetic waves 13 reach this receiver 17, the receiver 17 outputs a voltage corresponding to the polarization state to an output terminal 17a. For instance, the voltage corresponding to '1' is outputted when a linear polarized light parallel to an (x) axis has been received and the voltage corresponding to '0' is outputted when a linear polarized light parallel to a (y) axis has been received. It is reception binary data 18 and matches with the transmission binary data 12.  By modulating the polarization state in such a manner, radio data communication is made possible.

Abstract: PURPOSE:To reduce the influence due to an increase in volume of the material when the material is solidified and to reduce twins, dislocations and the like by a method wherein an end part whose inside diameter is small is arranged at the upper part in an inside container slidably detachable along the inside face of an outside container, melting and solidification are executed, the inner container is turned up-side down and a second melting operation is executed. CONSTITUTION:The inside diameter of the upper part of an inside container 12 with which a crystal raw material comes into contact, the inside diameter of the upper part is smaller than that of the lower part. The container comes into contact with an outside container 11 and can be moved smoothly. When a first heating, melting and sodification operation is executed, the opening part of the inside container 12 is set on the upper side with reference to the gravitation. The raw material is melted and cooled gradually; it is reshaped and solidified to the shape of the inside container 12. Before a second heating operation is executed, the inner container 12 is turned up-side down; at a second melting operation, the container is dropped from the upper part. After confirming the single crystal raw material inside the container, the container is moved upward. Alternatively, the temperature at the upper part is kept low as compared with the lower part. The temperature as a whole is lowered. Thereby, a single-crystal body is manufactured. At the second melting operation, air bubbles do not enter the inside container; the diameter can be controlled easily; a strain, a stress and a dislocation can be reduced easily.
