摘要： PURPOSE:To keep the curvature of a reflective film constant and to stabilize a focal length by providing a check valve in the reflective film and providing a projecting piece on a frame and flowing in and out a gas by automatic opening and closing of a disc part to control the projecting piece. CONSTITUTION:A check valve 20 is provided in the center part of a reflective film 10. A projecting piece 50 whose projection length can be controlled is provided on a frame 30. When a prescribed gas pressure is always applied from, for example, a nozzle 60, a differential pressure between the high pressure side and the low pressure side is always kept constant in set mutual positions of the check valve 20 and the projecting piece 50. Consequently, the curvature of the reflective film is kept constant, and the focal length is stabilized in a certain position.

摘要： PURPOSE:To improve the flow rate characteristic in a low flow rate region, by utilizing the self-exciting vibration of a vibration body due to flow and arranging a column behind the vibration body having a vibration shaft bonded thereto in parallel to the vibration shaft. CONSTITUTION:A trigonal prism-shaped vibration body 1 is bisymmetric with respect to a vibration shaft 5 to allow the front surface 3 thereof to oppose to flow and vertically supported in a freely revolvable manner with respect to the flow by the vibration shaft 5 positioned a little to the front along the center line of the vibration body 1 and the tail fin part 4 thereof is positioned on the downstream side to be subjected to the swinging vibration proportional to the flow rate of a fluid. The column 2 arranged parallel to the vibration shaft 5 is provided at the position slightly separated from the rear end of the tail fin part 4 at the rear position of the vibration body 1, and the sizes of both of the vibration body 1 and the column 2 and the interval therebetween are determined at experimentally pref. positions. By this method, linearity is obtained even in a low flow rate region of 5m /hr and the expansion of a measuring range to the low flow rate region becomes possible by a simple remodeling.

摘要： PURPOSE:To contrive to track the sun by pivoting a curved surface mirror by the combination of a curved surface mirror being pivotably supported and a heat sensing part which is expanded or contracted due to the amount of solar ray collected by the curved surface mirror. CONSTITUTION:A bucket type curved surface mirror 1 is composed of a parabolic surface 2, a spiral surface 3 and a side plate 4. The solar ray incident on an opening part 5 is reflected toward a coil spring 6 side forming a heat sensing part by the parbolic surface 2 and the spiral surface 3. A bias coil spring 14 acting as a tension spring is arranged in a permeable cylinder 7 in addition to the coil spring 6 and a piston 12. The coil spring 6 is formed of a spiral-shaped wound wire made of a shape memory alloy, accordingly, the curved surface mirror 1 can be pivoted with the moving of the sun, thereby, the tracking of the sun can be achieved.

摘要： PURPOSE:To simplify constitution as well as raise the operational accuracy by controlling an automatic switching valve by a cam rotating at a definite speed. CONSTITUTION:The roller 25 is in contact with the peripheral surface 18a of the notched disk cam 18 and moves in a sliding manner the switching control lever 23 vertically. When the lever 23 is situated upwards and the spool valve 14 is closed, the inside pressure of the pressure container 4 is gradually raised and the inflow of gas is stopped. When the notched portion 18b of the notched disk cam 18 comes below the roller 25, the roller 25 falls down into the notched portion 18b, the spool 16 is pulled down, and high-pressure gas is supplied to the gas-consuming apparatus 5. When the bellows 8 shrinks to some extent, the switching control lever 23 is pushed up. Exact operation can be obtained with such a simple structure.

摘要： PURPOSE:To readily correct the flux of fluid by a method wherein the moment of inertia of a vibrating object which self-excitingly vibrates according to the change of a fluid is adjusted, using a control device for the moment of inertia. CONSTITUTION:If a control gear 15 is moved upward and downward by operating a control lever 15a which constitutes a control device of the moment of inertia, the degree of the opening and closing of a centrifugal pendulum can be adjusted according to ascending and descending position of a slide shaft 12. Consequently, the moment of inertia of self-exciting vibrating body 16 is freely changed and controlled as a different variable irrelevant to the flowing speed of the fluid. Thus, the flux of the fluid to be measured can readily be corrected by performing proper calculation.

摘要： PURPOSE:To enable the measurement of pressure both with excellent sensitivity and accuracy, by a method wherein a medium varying with changes in pressure is connected to a mirror with one end thereof fixed, a collimator lens is placed in front of the mirror and further, a spot light source and a optical position detector are provided almost at the focal position of the lens. CONSTITUTION:A spot light source 1 and an optical position detector 2 are arranged almost at the focal position of a collimator lens 3. Light from the spot light source 1 is made parallel passing through the collimator lens 3 and reflected with a mirror 4 to form an image on the detector 2 passing through the same lens 3. As the mirror 4 is connected to a diaphragm 5 by a pin 6 with one 4A thereof fixed, the angle of the mirror 4 varies with the displacement of the diaphragm 5 to vary the imaging position on the detector 2. The displacement of the diaphragm 5 can be converted in a wide range by the selection of the fixing position of the pin 6 and the focal length of the lens 3 with respect to the mirror 4.

摘要： PURPOSE:To make constitution simpler, cost lower and performance higher by sticking tightly a reflecting film which is soft and has a metallic gloss with the metallic gloss surface on the outside to the aperture of a drum-shaped vessel having a circular aperture and evacuating the inside of the vessel. CONSTITUTION:An evacuating nozzle 2 is provided to a drum 1 for evacuation consisting of a rigid resin, metal, etc. and having an aperture. A soft reflecting film 3 is attached into the aperture by means of a lock ring 4 and bolts 5 in using a gasket or the like in such a way that airtightness is maintained in the drum. When the air in the drum is gradually evacuated through the nozzle 2, the film 3 is sucked to the inside of the drum to form a concave face. If the degree of evacuation is adjusted in this stage, the position of the focus 6 of the concave reflecting mirror can be adjusted within the permissible range of the elongation of the film. After the inside of the drum is evacuated until the prescribed focus is obtd., the valve for the nozzle 2 is closed to maintain the reduced pressure in the drum. The convave face formed to the film 3 in such a way is used as a reflecting mirror, by which the constitution is simplified, the cost is reduced and the performance is improved.

摘要： PURPOSE:To reduce an equipment cost by utilizing the curved surface of a light reflecting film formed when a light reflecting film having resilience and a transparent film or resin plate, glass plate, etc. are extended to a circular frame so as to face each other and a gas is sealed under pressure to the inside thereof. CONSTITUTION:A light reflecting film 1 consisting of a resin film deposited by evaporation with aluminum and a light incident side transparent resin sheet 4 or resin plate, glass plate 4' are attached to a circular frame 2 consisting of a hard resin or light metal, etc. by using a gasket in a flange type in such a way that the inside thereof is made airtight. Air or other inert gas is then forced into such assembly through a gas introducing port 5 to inflate adequately the light reflecting film. The inflation is adjusted by increasing or decreasing the slack in the stage of attaching the light reflecting film or filling of the air or the gas. When the filling of the air or the gas ends, the material to be heated is exactly directed toward the sun and is set in the focal position to start the use. The equipment cost is thus reduced.
