Title: Variable focal length lens
Inventor: NAKAYAMA HIROKI
IPC: G02B15/14
Filed: 1985-06-25
Abstract: PURPOSE:To reduce aberrational variation during power variation and to realize compact constitution by providing at least one distributed index lens in the 2nd lens group. CONSTITUTION:The lens system consists of the 1st positive lens group I and the 2nd negative lens group II successively from an object side and the object- side lens of the 2nd lens group II consisting of two lens elements is the radial type distributed index lens having positive transfer power, thus forming a two- group type compact zoom lens wherein the 1st lens group I and the 2nd lens group II move during power variation. Thus, the distributed index lens is applied so as to suppress an increase in astigmatism on a high field angle at a wide-angle end normally to the contrary, thereby reducing the astigmatism at the wide angle end. Further, the spherical aberration at the final end R6 of the 1st lens group I which tends to become under at a telephoto end is compensated to an over side by the transfer power in the distributed index lens to compensate the spherical aberration.

IPC: B22F3/10
Filed: 1978-11-11
Abstract: PURPOSE: To make possible sintering at lower temperature than before and enable metal muffle case to be used by heating the powder metal of Fe base containing Cr in a N 2  atmosphere and subjecting the same to diffusion sintering.  
     CONSTITUTION: The lubricant used at the forming of metal powder is removed of lubricants in a pre-treating furnace 1, after which it is sintered in a sintering furnace 2 and is cooled in a cooling chamber 3, thence the sintered product is widthrawn from a mesh belt 5. At this time, N 2  gas is introduced through N 2  gas inlet 7 to maintain the spacing between metal curtains 6 in a N 2  atmosphere. Since the N 2  gas is stably supplied at dew point -70°C or less and residual O 2  2ppm or less, sintering at 1150°C or less becomes feasible and it becomes possible to use a metal muffle case 4. In addition, a mesh belt 5 may be moved in endless form in the case 4 and therefore continuous sintering becomes easy.
