Title: Circular waveguide line
Inventor: UCHIDA SHIGEJI
IPC: H01Q13/22
Filed: 1988-08-29
Abstract: PURPOSE:To increase the degree of freedom of the design of other part of a circular waveguide path by using a conductor torus fitted to a lower conductor so as to match the connection part. CONSTITUTION:The torus matching body 7 has nearly the same diameter as the diameter of the bottom face of a conical matching body 6 and matches the impedance of a coaxial cable 8 and the impedance of a guide space 9 made of a slit plate 1, a bottom plate 2 and an outer peripheral plate 3 with the synergistic effect with the conical matching body 6. The impedance of the coaxial cable 8 and the impedance of the guide space 9 are matched by the synergistic action between the torus matching body 7 and the conical matching body 6 in this way. Thus, the reflection caused at the connecting point between the coaxial cable 8 and the impedance of the guide space 9 is reduced. Thus, the coaxial cable with a free size is connected without being limited by the interval of the circular guide lines.

IPC: F02F3/00
Filed: 1991-07-31
Abstract: PURPOSE:To prevent the rotation of ceramic piston head portion by making the axis-normal section of the outer periphery of the ceramic piston head portion, one which is not in the form of a complete circle, or one which is in the form of a polygon more than square. CONSTITUTION:The outer peripheral portion of a molten-metal-covered ceramic piston head 2 of a ceramic-inserted piston 1 is shaped into the form which is not a complete circle when viewed in a section normal to the axis of the piston head, for example, either a form which is not a complete circle and which is formed with a spherical recess, or a form which is not a complete circle and which is formed, at the rear end, with a spherical deep groove. Or alternatively, the outer peripheral portion of the ceramic piston head 2 is shaped into a form which is square or more polygonal when viewed in a section normal to the axis of the piston head, in other words, a form which is multi-cylindrical. Even when a clearance is produced at the boundary portion between the ceramics and the metal, during the engine operation, as a result of the difference in thermal expansion between the two, the outer piston-head periphery portion configuration serves to prevent the rotation of the piston head portion.
