Abstract

PURPOSE:To form easily a superhigh pressure area in a vessel by making a gas container vessel provided with a superposed pipe having an opposed lower end, on the lower part of a closed vessel, descend to a deep sea by a weight, and generating an atmospheric pressure equal to a high hydraulic pressure in the vessel. CONSTITUTION:A high pressure compressed gas chamber 7 and a gas container vessel 3 consisting of a closed vessel 1 formed by a compressed gas containing chamber 9 connected by a flexible pipe 8 under said chamber 7 are suspended with a rope 6 from a ship A. A suspended pipe 2 whose lower end part is opened 5 is provided on the lower surface of said gas containing chamber 9, and a weight 4 is suspended by a wire rope 11. This device is made to descend into a deep sea whose water depth is about 10,000m, a high pressurized sea water of the deep sea goes in from the opening 5, and the superhigh pressure area of a large capacity is formed in the closed chamber 1. In this way, the high pressure area in which the manufacture of a large-sized sintered ceramic lump by a hot press, and a work under the high pressure of a high pressure chemical reaction, etc. can be executed is obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to the generation of high-pressure regions used in press molding, high-pressure chemical reactions, deep-sea exploration, and the like.

``Conventional technology'' Conventionally, sintering by hot press (published on May 10, 1978, enlarged first edition, published by Shusho Okazaki, published by Gakuken Co., Ltd., Ceramic Dielectric Engineering, pp. 233-240) has been performed on the ground in 1000's. 9/crt and 800°C, the ceramic to be sintered was limited to small pieces.
It was difficult to corrugate large objects such as car engine bodies using hot-pressed sintered ceramics.
It was also difficult to easily obtain high-pressure chemical reaction regions and high-pressure regions for deep sea exploration.

"Problems to be Solved by the Invention" The purpose of the present invention is to easily obtain a high-pressure area that can perform mass production of large sintered ceramic lumps by hot pressing, high-pressure chemical reactions, deep sea exploration, etc. It is.

``Procedures and Means for Solving the Problems'' The present invention involves lowering a gas containing container, which has a vertical pipe with a bottom opening at the lower part of the closed container, into water using a weight, and then lowering the lower end of the vertical pipe. A method and apparatus for generating a high pressure region characterized in that water enters through an opening and gas pressure equal to the external water pressure is generated in the container.

``Function'' Therefore, all the gas is contained in a container with a vertical pipe with an opening at the lower end at the bottom of the closed container, and the illumination of a weight connected to the above opening is carried out.
When the container is lowered into the water using vertical ropes, water enters from the lower end of the vertical pipe and compresses the contained gas according to the water pressure, and the compressed gas becomes equal to the external water pressure through the container wall. It is maintained. This compressed gas pressure increases with increasing water depth and can suppress high pressure areas.

``Example'' As shown in FIG. 1, a gas container 3 is lowered into seawater from a ship A using a vertical rope 6. Is Ship A located in the Mariana Sea? Fi (depth of about 11,000 m), Philippine Trench (depth of about 1 oooom), Izu, Unhotokai @ (depth of about 9 soom), etc. As shown in FIGS. 1, 2, 5, 8, and 9, the three storage containers have a high-pressure compressed gas chamber 7 and a pressurized gas chamber connected therebelow via a flexible tube 8. It consists of a closed container l formed by a gas storage chamber 9, and the entire lower end rRJ port 5 is located downwardly of the gas storage chamber 9.
A vertical pipe 2 is provided. A small compressed gas storage chamber IQ may also be provided in the middle of this vertical pipe 2 (FIGS. 8 and 1Q).

Then, the hanging 4 is connected to the opening 5 with a wire rope 11. The high-pressure compressed gas chamber 7 and the compressed gas storage chamber 9 are shown in FIGS. 3, 4, 6, 7, and 10.
As shown in FIGS. 14 to 14, the sealed container 1 can be formed into one piece. Air or an inert gas is used as the storage gas depending on the descending water depth, and the material of the storage container 3 may be a thin material such as a copper plate or a transparent plate. As shown in FIGS. 8 and 14, the airtight container 1 accommodates a hot press sintering mold 12 and its differential pressure compression piston I3. to accommodate.

The above-mentioned formwork 12 and piston 13 are indicated by 15 in the figure.
airtight flexible sheet, 16 heat sources, 17 heat 11x16 hoods, 18 in Figures 3 and 4 is a camera, 19 is a power supply,
Information code, flexible tube for connection of 20HM installation pipe 2, and 2I heat dissipation. Thermal energy generated as the pressure of the compressed gas increases is dissipated into the water through the walls of the container 3.

"Effects" Since the present invention is based on the above-described method and apparatus, not only can a large-capacity high-pressure or ultra-high-pressure region be safely and easily obtained by simply lowering the container 3 into water, but also a small-capacity high-pressure region can be obtained. can be used for deep sea exploration, etc.
