Abstract: PURPOSE:To enable a utilization efficiency of light energy to be improved by constituting an incidence optical system with a capacitor lens where an image-side focus is placed at an incidence edge of a transmission optical system or an irradiation optical system and a fly-eye lens which is placed ahead of it. CONSTITUTION:Each cylindrical lens 9 constituting a fly-eye lens is provided with a nearly equal square-type open aperture and allows a sunlight S to be subjected to wave front division on the open surface. Each lens 9 generates a minute secondary light source of sun on its focus and constitutes a minute light source group with an equal brightness which is distributed in mesh shape as an entire lens 8. A light flux which is emitted from this light source group is gathered by a rear capacitor lens 10 and is mixed on an incidence edge ST of a transmission optical system or an irradiation optical system which is placed at the rear. When a length d and an effective radius r of the lens 9 are determined for fluctuation psi of an incidence angle of the sunlight S which enters a calibration optical system so that an inequality (n; refractive index of the lens 9) is met, a condition where the secondary light source can stay within the open surface of a rear surface of the lens 9 for the fluctuation psi can be satisfied.

Abstract: PURPOSE:To reduce the level of reverse G during rerush in an atmosphere by mounting a development type control panel to increase an air brake force in the downstream region of a temperature boundary layer through sweating cooling, such as ablative cooling. CONSTITUTION:An outer structure 1 of an obtuse,angled head type capsule is provided on a surface with an ablative cooling part 11 and at the rear with a development type atmosphere brake panel 2. The atmosphere brake panel 2 is supported to a recovery device by means of a hinge 21 and opened and closed by an actuator 22. The atmosphere brake panel 2 is structured such that an ablative coolant is adhered on the surface of an aluminum or titanium honeycomb plate. Ablative cooling is a system where heat absorbing reaction of thermal decomposition is utilized and comparatively low temperature gas is discharged. The development type air brake panel 2 is located on the downstream of a temperature boundary layer containing a sweating cooling effect, such as ablative cooling, and through development of the brake panel, a rush direction projection area to a capsule mass is increased. This constitution relaxes the degree of reverse G during rerush in atmosphere.

Abstract: PURPOSE:To absorb the difference in elongation at the time of a high temp. with a platinum flange and to prevent the failure of an MI cable by parting the joining point between the platinum alloy flange and the root end of a winding frame at a required distance in an axial direction from the joining point of the flange and the connecting fitting. CONSTITUTION:The outer peripheral surface of the winding frame 1 is metallized and the platinum alloy flange 17 is fitted onto this surface and is joined by a high-temp. brazing material 18. An accepting hole 19 of the connecting fitting 16 and the outer peripheral surface of the flange 17 are brazed by a gold/nickel/palladium brazing material 21. The joining point of the brazing material 21 is so determined as to be parted by the distance l in the axial direction from the joining point of the brazing material 18. The MI cable 9 and the connecting fitting 16 are brazed by a gold/nickel/palladium brazing material 22 in an insertion hole 20. The distance l is thus provided between the joining points in such a manner, by which the displacement by thermal expansion is escaped by the bending of the flange 17 and the generation of the stress by the direct thermal elongation difference in the winding frame 1 and the joint part is obviated.
