The invention relates to a multilayered water-repellent film formed on a glass substrate by the sol-gel process. The film has a first metal oxide layer which is formed on the glass substrate by the sol-gel process and a second water-repellent layer formed on the first layer. As a first method for providing the film with superior durability of water repellency, mechanical strength and chemical resistance, the first layer is prepared by using a mixture of three specific sols which are respectively prepared from metal alkoxides or metal acetylacetonates. As a second method for providing the film with the above advantages, the second layer is prepared by using a coating mixture comprising a fluoroalkylsilane, tin oxide particles doped with antimony oxide, a silicon compound, water and an organic solvent. As a third method for providing the film with the above advantages, the second layer is prepared by using another coating mixture comprising a fluoroalkylsilane, tin oxide particles doped with antimony oxide, a silicon compound, water, an organic solvent and an acid.

A hydraulic elevator comprises a car, a hydraulic jack to drive the car, a hydraulic pump, and control means for controlling a flow rate of fluid flowing to or from the hydraulic jack thereby to control movement of the car. The control means comprises a main valve constructed so as to allow fluid the flow from the pump into the hydraulic jack when a pressure of the fluid is higher than a predetermined value thereby to effect upward running of the car, and to check a fluid flow from the hydraulic jack when the pressure of the fluid from the pump is less than the predetermined value, and valve control means including a plurality of pilot valves for controlling, when the pressure of the fluid from the pump is less than the value, the main valve to open and close, and wherein the valve control means controls the closing operation of the main valve along at least two different patterns.

The disclosure relates to a metal oxide film formed on a glass substrate by a sol-gel method using a solution of at least one metal alkoxide or acetylacetonate. Water which is in the amount ranging from 50 to 400 mol % of the at least one metal alkoxide or acetylacetonate, an organic solvent and a catalyst are added to the solution, thereby to form a first sol. To afford water repellency to the oxide film, a fluoroalkylsilane in the amount more than 0.30 mol % of and less than 3.0 mol % of the at least one metal alkoxide or acetylacetonate, or an alkylsilane compound in the amount more than 4.0 mol % of and less than 20 mol % of the at least one metal alkoxide or acetylacetonate, is added to the first sol, thereby forming a second sol. The concentration of the at least one metal alkoxide or acetylacetonate in the second sol is adjusted to fall within the range from 0.005 to 3.0 mol %. The second sol is applied to the glass substrate to form a gel film. The gel film is heated at a temperature not lower than 100.degree. C. The obtained oxide film is superior in durability of water repellency.

Described is a bent axis type variable displacement hydraulic machine which is provided with a hydrostatic radial bearing 23 and/or a hydrostatic thrust bearing 28 to support hydraulic reaction forces exerted on a cylinder block 8. The hydraulic machine is arranged to draw out a high oil pressure corresponding to the tilt angle of the cylinder block 8 through a variable throttle means 34, 37, 51 or 54 or through a control valve 77 or 78, and to supply the pressure to the hydrostatic radial or thrust bearing 23 or 28 thereby imparting to a hydrostatic supporting capacity commensurate with the tilt angle of the cylinder block 8 to support a rotational shaft stably while holding oil leaks to a minimum.

A floor level correcting device used in a hydraulic elevator comprises means for electrically detecting the vertical position of the elevator cage with respect to the floor landing and driving means for level correction, provided independent of a main power unit for driving the elevator cage. The detecting means comprises means provided in the elevator shaft and means provided in the elevator cage which detect, in co-operation with each other, the level of the cage with respect to the floor landing of the building in particular whether the cage is stopped in the proper landing position or shifted therefrom, so as to produce an electrical signal in accordance with the detected cage level to transmit the signal to the driving means for level correction. The driving means for level correction comprises an accumulator and an electromagnetic valve and the electromagnetic valve is actuated by the electric signal from the position detecting means, so that the hydraulic fluid in a cylinder forming a part of the driving mechanism of the elevator is withdrawn into a tank, or the hydraulic fluid in the accumulator is conducted into the cylinder to thereby correct the level of the cage.
