Title: Scanning type antenna
Inventor: TANAKA HIROKAZU
IPC: H01Q3/20
Filed: 1982-07-06
Abstract: PURPOSE:To obtain an optional aperture distribution, by tilting an axis of a scanning mirror to an axis of a primary radiator and turning the scanning mirror and a beam reflecting mirror around the primary radiator for attaining the change in the direction of antenna. CONSTITUTION:A conical-shaped ray group Rp taking an axis WW' as a center axis is converted into a cylindrical-shaped ray graoup Ra taking an axis UU' of an aperture A as a center axis with the scanning mirror 1 and the beam reflecting mirror 2. Further, a rate of power P(theta) included in an angle theta from the primary radiator 3 to total power Wpm given to the beam reflecting mirror 2 is expressed in equation 1. On the other hand, a rate of power Q(rho) included in a radius rho to total power Wam on the aperture A is expressed in equation 2. Since P(theta)=Q(rho), the rho to a theta is obtained by rho=Q<-1>P(theta). That is, even if the radio wave beam Wp(theta) of the radiator 3 is predetermined, a power distribution Wa(rho) on the aperture A is formed into an optional distribution by obtaining the relation between theta and rho from said equations.

Title: Coupling method and device using shape memory alloy tube fitting
Inventor: SHIGENAKA NAOTO
IPC: B21D39/04
Filed: 1995-05-17
Abstract: PURPOSE: To make use of the performance of a shape memory alloy and obtain corrosion-resistance by composing a configuration memory alloy tube fitting so as to practice necessary physical processing, after completion of coupling process by a configuration memory alloy tube fitting so that plastic deformation may show on the surface of the configuration memory alloy tube fitting. CONSTITUTION: A shape memory alloy composing a tube fitting 1 is heated upon positioning the tube fitting to the connecting section of a pipe 2. When the temperature reaches a transition starting degree, shape recovery action starts and the inside diameter dimension of the tube fitting 1 trends to shrink until it reaches the transition completion temperature t2 . At this time, because the outside diameter R2 of the pipe 2 is set larger than the inside diameter R0 of the tube fitting 1 in its early stage, deformation of the tube fitting 1 to the shrinking direction is restrained, tensile stress generates in the circumferential direction, and the pipe 2 is connected to the tube fitting 1 by stress acting on the pipe 2 in the radius direction.  Physical processing by means of shot or the like is applied to the outside circumference of the shape memory alloy composing the tube fitting 1 so that plastic deformation may show only on the outside circumferential part, and then relaxes stress only on this portion.

Title: Stress cone
Inventor: NAGAYA SHIGEO
IPC: H02G15/064
Filed: 1991-05-23
Abstract: PURPOSE:To produce a stress cone for power cable having good electric characteristics, high workability and prolonged service life. CONSTITUTION:The stress cone 16 comprises an insulating part 17 having a through-hole 19 for inserting a power cable 2 and an outer tapered part 20, and a semiconductive part 18 formed integrally with the insulating part 17. Fluororesin is then applied on the tapered part 20 and the through-hole 19 to form a fluororesin film 22. Since the fluororesin is applied while rotating the stress cone, the fluororesin intrudes even into the joint 24 of the insulating part 17 and the semiconductive part 18 thus forming the through-hole smoothly. Consequently, breakdown voltage increases, cable insertion work is simplified, and the stress cone follows up thermal expansion.
