Title: Method and apparatus for forming image of cross section of concealed place
Inventor: TSUNASAKI MASARU
IPC: G01S13/88
Filed: 1991-08-20
Abstract: PURPOSE:To obtain the sufficiently clear contrast of variable density even in the deep place in soil by amplifying and correcting a received signal so as to supplement the attenuated amount caused by the depth of a concealed place, and forming the image of a cross section based on the signal. CONSTITUTION:The electromagnetic wave emitted from a transmitting antenna 5 is received with a receiving antenna 6. The output is supplied to a high-frequency amplifier circuit 8 through a line 7. The attenuated amount caused by soil, which is a concealed place, is aupplemented by amplifying the output of the antenna 6. In response to the time difference from the time when the transmitted signal is imparted from a pulse generating circuit 4 to the antenna 5 to the time when the output is obtained with the antenna 6, i.e., the depth of the soil 1, the amplification degree is made larger with the increase in depth. The output level of the antenna 6 is corrected more largely. The signals are sampled with a sampler 10 and digitized. The specified processing is performed in a processing circuit 11. Thus, the image of the cross section having the large contrast of variable density is obtained regardless of the depth.

IPC: H01L21/302
Filed: 1989-08-11
Abstract: PURPOSE:To enable the photo-excited etching effect combined with an especially effective mask-making means to be brought about by a method wherein ion is implanted in selected regions on the surface part of an element to be etched while the element is photoexcitedly etched away using the implanted regions as masks. CONSTITUTION:Ion is implanted by ion beams in selected regions 2 on the surface part of a substrate 1 as an element to be etched. Next, when the whole surface is irradiated with excited beams 4 in existence of reactive gas 3, any other parts excluding the regions 2 are rapidly etched away; accordingly, the parts beneath the regions 2 only are left without being etched away by vertically irradiating the surface of the substrate 1 with the excited beams 4. The regions 2 may be removed later. Through these procedures, the dryetching process including the mask-making process can be performed so that the process continuation and the reduction in mixed pollutant may be assured.

Title: Water-stopping structure of underground tank
Inventor: YASUNAGA MASAMICHI
IPC: B65D88/76
Filed: 1993-07-30
Abstract: PURPOSE:To prevent underground water from penetrating into the bottom of an underground tank by providing a freezing pipe near the contact area between a skeleton concrete of the underground tank and the ground to freeze the surrounding concrete and ground by circulating nonfreezing low temperature fluid. CONSTITUTION:A freezing pipe 11 is laid near the contact area between a bottom plate 7 of an underground tank of concrete and the ground 5 comprising a water-impermeable layer along the circumference of the plate 7. Next, a nonfreezing low temperature fluid such as a water solution of ethylene glycol is circulated through the pipe 11 to freeze the concrete and ground around the pipe 11 to obtain a frozen part 13, thus preventing the underground water from penetrating into the bottom of the tank. As a result, water stopping can be surely achieved. And since the concrete and ground having large specific heat is located deep in the ground and frozen, once the concrete and ground have been frozen, a large amount of heat is not required to keep the frozed state. Particularly in the case that, as is the case of an LNG underground tank, the ground around the tank has been cooled by the cold load of LNG, required amount of heat is small and hence a refrigerator 15 of small capacity can be used.

Title: Soft contact lens
Inventor: HONDA TOMOJI
IPC: C08F24/00
Filed: 1995-07-25
Abstract: PROBLEM TO BE SOLVED: To obtain a contact lens having a high water content, flexibility and excellent long-term stability by grinding and polishing a copolymer comprising vinyl acetate and diallylidenepentaerythrite to form a lens and hydrolyzing the lens. SOLUTION: A crosslinked polyvinyl alcohol soft contact lens having a water content of 20-80 is produced by grinding and polishing a copolymer comprising 90-99.5wt.% vinyl acetate and 0.05-10wt.% diallylidenepentaerythrite under sprinkling with chilled water and hydrolyzing the lens. In this production, the above copolymer is shaped under cooling because it is soft and it is usually difficult to shape the copolymer into a lens by grinding and polishing at room temperature. For instance, it is cooled to -20 deg.C and shaped into a lens under cooling. Although the hydrolysis method is not particularly limited, the hydrolysis is performed by immersing the copolymer in an aqueous alkali solution. An article having flexibility and excellent long-term stability can be obtained.

IPC: G03B17/08
Filed: 1994-09-01
Abstract: PURPOSE: To obtain a waterproof case structure having high waterproof performance and excellent operability for closing a cover by forming waterproof seal of an elastic material which can absorb water to swell. CONSTITUTION: The seal material 26 attached to a rear cover 14 is made of an elastic material which can absorb water to swell. When waterproof seal 26 is made of the above-mentioned elastic material, in addition to a normal sealing action by its elastic deformation remarkable waterproof performance can be obtained since the waterproof seal 26 absorbs the water, when coming into contact therewith, and swells between the rear cover 14 and a camera main body 10. Therefore, it is unnecessary that the waterproof seal 26 is pressed with extraordinary great force between the rear cover 14 and the camera main body 10. Moreover, the deforming margin of the waterproof seal 26 can be set comparatively small, so that an operation for closing the rear cover 14 is executed with excellent operability without requiring great force.
