Title: Corrosion preventing apparatus for piping of water for fire-fighting
Inventor: ARAKAWA TAKESHI
IPC: A62C35/68
Filed: 1989-07-17
Abstract: PURPOSE:To prevent a corrosion in piping due to aged deterioration by giving a certain flow velocity to the inside of the supply line of water for fire-fighting and a loop header at the time of an accident other than fire and by providing the terminal parts of a plurality of branch pipes, where no certain flow velocity can be obtained, with drain valves to periodically change water collected therein. CONSTITUTION:A tank 1 is filled with water for fire-fighting to interior fire hydrants 9 by the shutoff operation of a fire pump 2 and the minimum flow rate of water for not raising the temperature of the water for fire-tighting is returned to the tank 1 through a stop valve 10, a flow orifice 11 and a check valve 12. In the supply line 5 of the water for fire-fighting and a loop header 7, 1-2 meters/second is obtained as a certain flow velocity. Also, because it is economically disadvantageous to give a certain flow velocity to water in branch pipes 8, fresh water can be supplied to substitute for collected water after the collected water has been discharged from drain valves 18 at the time of a regular examination, etc. Thus, it is possible to prevent the corrosion of a piping of water for fire-fighting.

Title: Image-forming material and image-forming method using this material
Inventor: TAKEUCHI SATOSHI
IPC: G03C5/56
Filed: 1980-12-23
Abstract: PURPOSE:To obtain a good desired visible image by suppressing physical development with a photodecomposable compound having a diazo or triazo group. CONSTITUTION:A hydrophilic binder layer 2 containing a metallic compound becoming metallic development nuclei on reduction, and a diazo or triazo group is formed on a substrate 1 to provide an image-forming material, which is patternwise exposed, and brought into contact with a reductant to form metallic developing nuclei, thus completing the first developing step. Then, the material is brought into contact with a physical developing solution containing reduceable metallic ions and the reductant to form an image consisting of metallic particles depositing and growing from the reduceable metallic ions on their reduction on said nuclei, thus completing the second developing step. Since said compound does not decompose in the undeveloped area, the physical development is suppressed. Use of a reducing agent fast against the physical developing solution permits the first and the second developing steps to be carried out at the same time.

Abstract: PURPOSE:To make low-pressure air usable for combustion air and to reduce power consumption by disposing an air chamber having a pipe for supplying air for combustion, a small-diameter short pipe, a combustion chamber having a pipe for supplying fuel and an ignition means, a restricting part and a combustion gas exhaust pipe sequentially on the same axis. CONSTITUTION:Air supplied through a small-diameter short pipe 9 from an air chamber 8 to which it is supplied through a pipe 2 for supplying air for combustion and fuel supplied from a pipe 3 for supplying the fuel are combusted explosively by an ignition means 4 in a combustion chamber 5 and become hot air, which is exhausted into a combustion gas exhaust pipe 6 through a restricting part 7. On the occasion, the pressure inside the combustion chamber 5 becomes high temporarily and a back pressure thereof is applied to the air chamber 8 through the short pipe 9, whereby the air in the air chamber 8 is compressed temporarily to be of high pressure. When the inside of the combustion chamber 5 comes to be of reduced pressure subsequently, the compressed air of high pressure in the air chamber 8 flows rapidly into the combustion chamber 5, giving rise to a subsequent explosion cycle. According to this constitution, low-pressure air can be used for the air for combustion and power consumption can be reduced.

Title: Aromatic
Inventor: IMAI KATSUMI
IPC: A61L9/12
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To provide an aromatic which is durable as to the emission of aroma by impregnating a piece of wisteria with an aromatic solution. SOLUTION: A piece 1 of wisteria (also called rattan, climbing palms growing in the jungles of Southeast Asia), from which the bark has been stripped, is impregnated with an aromatic solution to constitute an aromatic A. The piece 1 is obtained by cutting raw lumber, from which the bark has been stripped, into an appropriate length along its longitudinal direction, and passing it through a molding machine to form a column that is 8mm in diameter and 10mm long; the piece 1 is then impregnated with the aromatic solution using a certain means (e.g. soaking) to obtain the aromatic A. The aromatic solution is Montana pine, eucalyptus, rosemary, lavender, peppermint, juniper, natural menthol, etc.  Thus, since the aromatic solution impregnating vessels in the piece evaporates gradually, the aromatic that is durable can be provided, and since the piece that is the major part of the aromatic is lightweight and very elastic, it is suitable for use as the material (core) of a pillow, for example, because of its good feel as well as aroma.
