Title: Small zoom lens
Inventor: NAKAYAMA HIROKI
IPC: G02B15/16
Filed: 1984-10-05
Abstract: PURPOSE:To compensate aberration efficiently over the whole screen by constituting the 2nd lens group of the 2-1th lens having concave surfaces on both the sides and the 2-2th meniscus-like lens turning its convex surface to the image side and having negative refractive force which are arranged successively from the object side. CONSTITUTION:The 2nd lens group is constituted of two negative lenses, i.e. the negative lens having concave surface on both the sides and the negative meniscus lens turning its concave surface to the object side which are arranged successively from the object side. Since the negative meniscus lens is improved in refractive force without increasing the curve of the image surface and the 1st lens of the 2nd lens group forms concave surfaces on its both sides, two negative lenses of the 2nd lens group take partial charge of negative refractive force each other and both the radiuses of curvature are moderate, so that the generation of a curve on the image surface is reduced at the generation of aberration. Consequently, a small zoom lens reducing the variation of the curve on the image surface due to variable power and efficiently compensating the aberration over the whole screen can be obtained.

Abstract: PURPOSE:To prevent the increase of concentration of gold or platinum even in the vicinity of surface by diffusing the impurity a concentration of which does not become high even in the vicinity of surface in advance of diffusing gold or platinum and substituting gold or platinum for the diffused impurity. CONSTITUTION:For example, chromium is diffused in an Si wafer. Diffusion temperature is so selected that the concentration of chromium becomes equal to or slightly higher than the concentration of gold which is to be obtained finally. Next, after removing the residual chromium on a surface by aqua regia or the like, gold is diffused. At this time, if the diffusion temperature of gold is so selected that it is the temperature by which the gold can be mostly substituted for the previously diffused chromium or over that temperature, and is also the temperature by which the concentration in a substrate in case of diffusion of only gold becomes nearly equal to the concentration of chromium, or under that temperature, the previously diffused chromium is consequently substituted by the later diffused gold. The concentration of gold 32 in case of diffusion of only gold is changed into the concentration distribution of gold 31 when the chromium is substituted by gold, which is constant regarding the depth direction from the substrate surface.

Abstract: PURPOSE:To cut off the drafts to improve thermal efficiencies of cooling and heating by providing an air passage changeover means and a means for detecting differential pressure between the interior and exterior of a room to control the air passage changeover means based on the output of said means for detecting differential pressure. CONSTITUTION:A damper 6 for changing over air passages of an outdoor air inlet port 4 and an indoor air suction port 5 and a differential pressure detection means 7 for detecting differential pressure between the interior and exterior of a room are provided. The changeover of air massages of the damper 6 is performed in such a manner that signals from the means 7 are received to rotate a stepping motor 9 through a control means 8 which controls the opening of the damper 6 depending on the output level of said signals. During a usual operation, the damper 6 is set on the side of indoor air introduction. When the switch of a ventilation fan is turned on, the pressure in the room becomes negative, which pressure is detected by the means 7, whereby the damper 6 is opened to the side of outdoor air introduction by the motor 9 to take in outdoor air, so that the differential pressure of the room is eliminated. As a result, drafts through doors etc., are restrained and since outdoor air introduced is air-conditioned, uncomfortableness is avoided.
