摘要： PROBLEM TO BE SOLVED: To provide an air refrigerant type refrigerator suitable for continuous operation for a long period.
SOLUTION: A cyclone type dust collector is interposed in a circulation route for the air refrigerant of the air refrigerant type refrigerator. Means for promoting the solidification of moisture content in an air refrigerant are installed on the front stage of the cyclone. These means include a humidifier, a fine particle sprayer, or a bar-like member installed in a pipe. Accordingly, the moisture content is solidified and grown to ice particles of a grain size suitable for collecting them by the cyclone. The ice particles are collected by the cyclone and dry air is supplied to the refrigerator. In this refrigerator, since the supply of cooling air is not stopped for defrosting, dry cooling air is continuously supplied to the refrigerator over a long period.

摘要： PROBLEM TO BE SOLVED: To minimize an extrusion pressure by forming a presser metal fitting on the atmospheric pressure side more thickly than a presser metal fitting on the hydraulic pressure side. SOLUTION: A presser metal fitting 6 on the atmospheric pressure side is formed more thickly than a presser metal fitting 5 on the hydraulic pressure side while a clearance S2 on the atmospheric pressure side is made smaller than a clearance S1 on the hydraulic pressure side. In the case when a sluice gate door 3 is closed, the sluice gate door 3 is slidingly closed while the head of water stop rubber 7 projected by the hydraulic pressure on a rear side is being pushed transversely. The head of the rubber in the early stage is separated from the sluice gate door 3 but when the sluice gate door 3 comes in contact with the head of the door 3 of the sluice gate later, a hydraulic pressure is loaded transversely on the head of the rubber, thereby producing the falling down of the head of the rubber on the atmospheric side. The root of the head of the rubber is swollen to the atmospheric side by this falling down of the head. Since the presser metal fitting 6 on the atmospheric pressure side supports this swollen area, the amount of the falling down of the water stop rubber 7 is relieved. Therefore, the water stop rubber 7 when closing the door 3 of the sluice gate is not easily sandwiched with the door 3 of the sluice gate and the presser metal fitting, thereby extending the service life of the water stop rubber.

摘要： PURPOSE: To obtain high waste gas treating performance with a small quantity of slaked lime by forming an uniform slaked lime sticking layer on plural bag filters. CONSTITUTION: Plural filter cloths 6 are installed in a vessel 1. In a bag filter house hopper part in the lower part of the vessel 1, a waste gas inlet 2 is installed. In the bag filter house hopper part, three inflow waste gas dispersing flow spreader plates 13-15 each having an opening of different size are installed opposite to the waste gas inlet 2. The openings of the flow spreader plates 13-15 decrease in size in that order. Waste gas flowing in from the waste gas inlet 2 is dispersed by these flow spreader plates 13-15 and is caused to uniformly flow to the bag filter house hopper part. Therefore, slaked lime flowing in together with the waste gas is uniformly stuck on the surface of the bag filters 6 to effectively treat the waste gas.

摘要： PROBLEM TO BE SOLVED: To provide a gate which excels in the effectiveness in transportation and installation and which can retain the same degree of performance as per the conventional arrangement. SOLUTION: A gate 11 is to be installed on the way of a circular pipe line 18 in which the flow speed is comparatively low and is equipped with a gate part 12 having a door 15 to open and shut the flow passage and an upstream 14 and a downstream casing 16 and also an upstream 13 and a downstream transition 17 installed upstream of the casing 14 and downstream of the casing 16, respectively, wherein the section form of the passage of the gate part 12 is rectangular, while the section forms of the passages of the transitions 13 and 17 transfer from one end on the gate part 12 side toward the other end from the same rectangular shape as the gate part 12 to the same circular shape as the line 18 without changing the section area. The length L of the transitions 13 and 17 is made below one half of the gate height T so as to generate a weight to enable consolidation with the casings 14 and 16 and also kept over 0.36 times as large as the gate height T so as to suppress the energy loss of the flow into within a minor extent.

摘要： PURPOSE:To assure straightening of turbulent flow caused by an upstream valve of a plurality of valves disposed in series in a pipeline by disposing between adjacent valves a straightening resistance plate of a suitable thickness having a number of small holes and extending across the flow. CONSTITUTION:There are provided in a pipeline 1 an upstream valve 3 and a downstream valve 4 disposed in series for pressure or flow rate adjustment, and a straightening resistance plate 5 of a thickness l having a number of circular small holes of a diameter d is disposed between the upstream and downstream valves 3 and 4 across the flow of fluid 2 and secured to the inner wall of the pipeline 1 by welding 7. The thickness l of the straightening resistance plate 5 and the hole diameter d are set in such a relation that l/d is larger than 3. If adjusting operation of the upstream valve 3 causes turbulent flow 8 downstream thereof, the turbulent flow 8 can be straightened by the straightening resistance plate 5 so as to prevent vibration of the downstream valve 4.

摘要： PURPOSE:To detect whether or not self-excited vibrations are danger by measuring hydraulic pressure which operates on a gate by a pressure sensor when the gate vibrates. CONSTITUTION:A model gate 1 is installed in a water flow and supported by a support arm 5 through a roller bearing 6 from outside the water flow. Further, the model gate 1 is excited vertically in the flow by a motor 2, a crank 3, and a rod 4 from outside. Consequently, the flow becomes a flow affected by the vibrations of the gate 1. The gate 1 receives a force from the flow when vibrating to the contrary. Then, the pressure sensor 7 fitted on the bottom surface of the model gate 1 measures the hydraulic force operating on the gate 1 when the gate 1 is in the vibrating state. Then, measured values of a displacement sensor 8 and the pressure sensor 7 are led to a phase different analyzer 9, which analyzes the phase difference between the displacement and hydraulic force to detect whether or not the self-excited vibrations are danger.

摘要： PURPOSE:To obtain sufficient strength and economical manufacturing cost and minimize the downpull by selecting the entrance angle of the bottom of a gate and length of a lip within a given value. CONSTITUTION:The form and dimension of the bottom of a sliding gate 1 are composed of entrance angle alpha=38 deg.-50 deg. and lip length L/L0=0.26-0.72. Under these conditions economical requirements for the structural strength are satisfied and the downpull can be reduced, (where the entrance angle: angle which the straight line passing the lower end of the lip makes to the horizon when the bottom plate of the gate is remolded by a circular arc with a radius of r at the rear part, L0: length of the lip when the inclination angle of the bottom plate is 0 deg.).
