Title: Pneumatic caisson
Inventor: KASHIMA YUTAKA
IPC: E02D23/04
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To easily confirm the location of excavation work by hanging a plurality of level rod members from a ceiling of a work chamber to the periphery of a wall surface of the work chamber in a manner being spaced predetermined intervals away from each other. SOLUTION: A plurality of level rod members are hung from a ceiling 8 of a work chamber 6 of a pneumatic caisson 1 in proximity to a wall surface 7 of the chamber in a manner being spaced predetermined intervals away from each other. A TV camera 22 is attached to an excavator 10, which shoots the level rod members, whereby the location of excavation work is recognized through the video.  Thus, even if a cutting edge 4 of the pneumatic casson 1 and/or the wall surface 7 of the work chamber 6 is buried in earth due to soft earth ground, and therefore the wall surface 7 of the chamber 6 is hardly viewed, or even if earth is spattered together with water at the time of excavation of the ground to soil the wall surface 7 of the chamber 6, the excavation location in the work chamber 6 can be positively recognized, and the excavation can be easily controlled while watching the video shot by the TV camera. These effects can be brought about by the pneumatic caisson of the above construction.

Title: Manufacture of linear superconductive material
Inventor: YAMAMOTO SUSUMU
IPC: B28B1/00
Filed: 1988-09-14
Abstract: PURPOSE:To make it possible to manufacture a superconductive material accommodating a sintered substance of a high superconductive property even though a material powder is filled in an outer tube member and sintered, by accommodating an Ag2O powder together with the material powder inside the outer tube member. CONSTITUTION:Inside an outer tube member with a closed section, a material powder is filled, and after the outer tube member filled with the material powder is plastic-processed, a heat treatment is applied to sinter the material powder. When a linear superconductive material is manufactured in such a way, a heat treatment is applied after an Ag2O powder is filled together with the material powder in the outer tube member. Since oxygen is fed at the inside of the metal tube body, in such a method, the metal tube body can be sealed up perfectly in the sintering process, and a complex oxide type superconductive material can be produced safely. In this case, however, the Ag produced after the O2 is released is liable to react with the superconductive sinter. Therefore, as one of preferable method, an Ag layer 2a is formed by coating the inner surface of the outer tube member 1 with Ag, for example, and after forming Ag2O3 in the presence of O2, the material powder 4 is filled.

Filed: 1987-09-16
Abstract: PURPOSE:To change the beam size with the small voltage and improve the connection accuracy between beams by installing a deflector inside two-stage projecting lenses and over a region longer than the lens interval. CONSTITUTION:A deflector 15 for changing the beam size is arranged inside two-stage projecting lenses 13, 14, and the length of this deflector 15 in the optical axis direction is set longer than the lens interval.

The lens interval can be decreased if the deflector 15 is not required to be lengthened, thus the aperture interval can be decreased, and the blur of the beam due to the space charge effect is reduced. The beam edge resolution corresponding to edges of the first aperture and the second aperture is reduced, and the connection accuracy between beams can be improved.
