Filed: 1990-11-13
Abstract: PURPOSE:To make an optical axis of a part of the apparatus perpendicular or parallel to a reference axis and to assemble the apparatus efficiently at low cost and adjust with high accuracy by inclining an acousto-optic element with a Bragg angle alpha to the reference axis. CONSTITUTION:A reflecting mirror 3, a beam splitter 2 and a reflecting mirror 6 are arranged on an optical axis O1 of an He-Ne laser 1. An acousto-optic element 4 and an acousto-optical element 8 are respectively arranged on the optical axes O2 and O3. Assuming that the Bragg angle of the elements 4, 8 is alpha, the optical axis O2 is inclined 2alpha to the exit optical axes OO1, OO2 of the elements 4, 8. That is, a perpendicular of a reference axis mm' of the element 4 is inclined alpha to the optical axis O2. Similarly, a perpendicular of a reference axis nn' of the element 8 is inclined alpha to the optical axis O3. As a result, the optical axes OO1, OO2 become parallel to each other seen from an absolute end of a mounting base 9 of the elements 4, 8. Accordingly, the optical axis of the part of the apparatus is made parallel or perpendicular to the reference axis, and therefore, assembly and adjustment of the apparatus can be carried out efficiently at low cost and with high accuracy.

Title: Planar antenna
Inventor: TSUTSUMI SUSUMU
IPC: H01Q1/42
Filed: 1991-11-22
Abstract: PURPOSE:To prevent the deformation of a radome due to a pressure and temperature change between the inside and the outside of a plane antenna by providing a round hole in the middle of a metal-made shielding plate, stretching a pressure adjustment film whose extension rate is larger than that of the radome and which is deformed elastically and closing the round hole air-tightly. CONSTITUTION:Since a difference from an air pressure is not caused between the inside and the outside of an enclosed package 4 in a steady-state, an adjustment pressure film 15 is not deformed but kept horizontal. Then the air pressure in the package 4 is higher (lower) than the air pressure at the outside of the package 4 at the air pressure rise (decrease) or the air pressure decrease (rise) at the outside of the package 4 caused by the expansion (contraction) of the air in the package 4 due to a temperature rise (decrease) between the inside and the outside of the package 4. Thus, the adjustment pressure film 15 is expanded outward (inward) from the round hole 14, the inner volume of the package 4 is larger (smaller) thereby decreasing (increasing) the air pressure in the package 4. Thus, the air pressure difference between the inside and the outside of the plane antenna is decreased through the deformation of the adjustment air pressure film 15, thereby preventing the deformation of the radome 2.
