摘要： PURPOSE:To make it possible to obtain low humidity air due to a full outside air introduction only by a freezer by heat-exchanging outside air with air behind two heat exchangers or coolers with defrosters. CONSTITUTION:Two coolers 5 having defrosters are disposed and dampers 6 for suitably switching the blast are provided in the airflow path behind respective coolers 5. A humid air supply airflow path and a dehumidified air lead-out airflow path behind the coolers 5 are connected in parallel to the heat exchangers 8 and 9. An air heater 11 utilizing condensation heat in the freezing cycle is provided in the air flowpath for dehumidified air behind the coolers 5. Further, suction pressure adjusting valves are provided in an air-cooled type heat exchanger 2 of a freezing circuit and a suction side pipeline of a compressor 1 so as to make it possible to prevent the overloading of the compressor and to dehumidify the coolers with defrosters even in winter season. Thus, low humidity air due to the external air introduction necessary for the painting operation can be obtained throughout a year only by the freezer.

摘要： PURPOSE:To improve the rust-resistance, abrasion resistance and the tenacity of abrasive/cleaning material while to use as grid and shot by containing respective wt% of C, Si, Cr, Cu. CONSTITUTION:1.5-3.2wt% of C, 0.2-1.2wt% of Si, 22-36wt% of Cr and 0.5-3.0wt% of Cu are contained in the abrasive/cleaning material. Consequently, corrosion resistance against sea water and clean water, abrasion resistance and tenacity are improved. Furthermore, it can be used as grid and shot.

摘要： PURPOSE:To remove fast buildup of black rust etc. nearly perfectly by spraying extra-high pressure water, cooled to a temperature range between zero and immediately before the solidification point, from a nozzle, and by providing a mixture slurry consisting of the sprayed water and fine crushed ice produced momentarily at part of the spraying. CONSTITUTION:From a pressurization means 2, extra-high pressure water is supplied to a heat-exchanger 4a of a cooling means 4 by the use of a pressure resistant hose 3, and only sensible heat of the extra-high pressure water is absorbed by the heat-exchanger 4a so that the water can be cooled to temp. range from 0 deg.C to immediately before the solidification point. This cooled water is sprayed from a nozzle 8b to the surface to be processed at a supersonic speed, while part of the sprayed water is permitted to freeze momentarily under the atmospheric pressure without requiring drop of the stream speed, and thus the sprayed water with crushed ice bits form a mixture slurry to run against the surface, so that even fast buildup on the surface such as black rust can be removed nearly perfectly and also that cutting of different types of material be performed efficiently.

摘要： PURPOSE:To perform cleaning work in the hold efficiently by fixing a guide support through a travel wheel to a lounge member secured to the outer wall of hull while projecting then fixing a holding section for fixing a plastgun telescopably and inclinably to the guide support elevatably. CONSTITUTION:A guide support 5 is fixed movably in longitudinal direction through a travel supporting section 6 onto the upper face member 3b and edge member 3c of a lounge member 3 to be secured to the outer wall of hull while projecting. Said travel supporting section 6 is provided with a travel wheel and a guide wheel. A holding section 7 is provided elevatably along said guide support 5 while a plastgun 4 is fixed rotatably and telescopably to said holding section 7. Consequently, cleaning work of the inner wall of hold can be performed efficiently without requiring a special guide rail through up/down motion, rolling and telescoping.

摘要： PURPOSE:To reduce the cost of a scaffold by providing scaffold mounting members to ladders leaning against a skeleton in parallel so as to project in a horizontal direction, and constructing scaffold members between the scaffold mounting members. CONSTITUTION:Ladders 1 are leant against a skeleton 5 so as to hold working places, coupling member 14 are inserted in the upper ends and lower ends of the ladders 1, and they are fixed with nuts 15 to connect the ladders to each other. After that, horizontal members 8 of scaffold mounting members 2 are interlocked with bases of horizontal members of the ladder 1, inclined members 11 and vertical members 10 are arranged to the outsides of vertical members 1c and are fixed with nuts. Scaffold members 3 stretching a lath 3b on a frame 3c are built between the horizontal members 8 of the scaffold mounting members 2, and fixed arms 3c are fitted to the horizontal members 8 to fix. Accordingly, a necessary scaffold can be easily assembled in a necessary place only.

摘要： PURPOSE:To remarkably improve a surface destruction effect by the simultaneously action of the grinding by sand and the impact of an ultra high pressure water jet by accelerating by colliding the sand and the ultra high pressure jet water exceeding the high speed air current at the throat part of a venturi type nozzle for sand injection. CONSTITUTION:The sand transferred by accelerating air current from a hose 6 with pressure air is accelerated by colliding with an ultra high pressure water jet blasted from a nozzle 5 exceeding the high speed air current at a throat part 2 at the throat part 2 of a venturi type nozzle 1 for sand injection to remarkably increase the injection sand speed of the outlet port of the venturi type nozzle 1 for sand injection. Moreover it is injected on the face to be destroyed necessitating impact destruction by enlarging the injection pattern and this face is destroyed by its impact.
