Title: Zoom lens
Inventor: IKEMORI KEIJI
IPC: G02B15/16
Filed: 1987-09-11
Abstract: PURPOSE:To reduce the size of the whole lens and to obtain a high variable power rate and excellent optical performance by specifying the refracting power of three lens group and the lens constitution. CONSTITUTION:When the zoom lens consists of three lens groups with refracting power, the ratio of the principal point interval E1w between the 1st group and 2nd group at wide-angle ends and the principal point interval E2w between the 2nd group and a 3rd group is set satisfying an inequality I. Therefore, the back focus at the wide angle end is shortened and the overall length of the lenses at the wide angle end is shortened greatly. Further, the ratio of the focal length f3 of the 3rd group and the focal length FT of the whole system at a telephoto end is set as shown by an inequality II. Therefore, while the excellent optical performance is maintained over the whole power variation range, the lens system is reduced in size on the whole. Consequently, the lens overall length is shortened and high power variation, i.e. about X3 power variation is obtained and the high optical performance is obtained over the entire power variation range.

Title: Cryostat provided with adsorber
Inventor: SAHO NORIHIDE
IPC: H01L39/04
Filed: 1988-09-14
Abstract: PURPOSE:To regenerate an adsorber as a cryostat is kept of an ultralow temperature by a method wherein a heating means is provided to the adsorber to make its temperature rise and concurrently a vacuum tank is exhausted by an exhauster. CONSTITUTION:All electric heater 9 of a heating means is fitted to the end of an adsorber 7, which is thermally integrated with a cryostat 3 through the intermediary of a rod 8 provided with a heat insulator. The adsorber 7 is heated with the electric heater 9 and when its temperature rises to a specified value or more, gas contained in the adsorbent is discharged. The gas leaked in a hermetically sealed empty space 5 is cooled down and brought into contact with the adsorbent inside the adsorber. 7 and trapped. When the gas concentration in the adsorbent reaches to a certain value, the adsorbent deteriorates in adsorbing property. And, as the degree of vacuum inside the empty space 5 deteriorates, the adsorber 7 needs to be degenerated. And, the above-mentioned separated gas is exhausted from the empty space 5 to a vacuum exhaust system 14 by opening a vacuum valve 13. At this point, as the rod 8 is provided with an heat insulator and the heat penetrating from the adsorber 7 to the cryostat 3 is minimum, the adsorber can be degenerated as the cryostat 3 is kept at an ultralow temperature.
