Abstract: An information providing system includes an information terminal which belongs to a user and a providing server which is connected to the information terminal through a network. In this system, the providing server transmits provision information from the providing server to the information terminal through the network. When receiving an update information which is for updating the provision information and includes relation information related to the user from the information terminal, the providing server calculates an information reliability degree indicating a degree of a reliability of the update information based on at least one of the relation information and the update information. The providing server updates the provision information based on the information reliability degree and the update information.

Abstract: A turbine flowmeter includes an impeller rotatably provided within a flow passage through which a fluid to be measured flows and comprising a rotary shaft which rotates together with the impeller, a pair of bearing part having bearing surfaces for axially supporting the rotary shaft, a holding part for holding the bearing part and provided on the flow passage, an oil accumulating space defined by an end portion of the rotary shaft and bearing surfaces facing respective sides of the end portion, an oil accumulating part provided on the holding part and filled with the lubricating oil to be supplied to the oil accumulating space, an oil supplying part for supplying oil to the oil accumulating space which part comprises a capillary part connected on one end direct to the oil accumulating part and communicated on the other end to the space, wherein the lubricating oil is supplied to the space via the oil supplying part from the oil accumulating part by capillarity introduced in the oil accumulating part and the s

Abstract: Disclosed is a control apparatus for correcting the measurement of flow rates for use with a turbine-type flow meter in which the rotation of a turbine rotating in response to the flow velocity of fluid to be measured is detected to produce pulses which are, in turn, integrated to measure the flow rate of the fluid. The apparatus operates to obtain a value representing the rate of reduction in the flow rate from the pulse cycle in order to detect a first time at which the reduction rate increases above a first predetermined value and a second time at which the reduction rate decreases below a second predetermined value, produce a correction value on the basis of the pulse cycle at the second time and the time lag between the first and second times, and integrate pulses other than those generated in the period of time between the first and second times, adding the correction value from the correction value producing means to the integrated value.

Abstract: A wrist mechanism including: at least three rigid elements each having an element axis, said rigid elements being connected in series so that adjacent two elements are rotatable relative to each other about a rotation axis, the rotation axis of said two adjacent rigid elements intersecting said element axes thereof, each rotation axis of each rigid element intersecting adjacent rotation axis; a first rotating mechanism for rotating every second rigid element relative to the other rigid elements; a second rotating mechanism for rotating the other rigid element relative to said every second rigid element.

Abstract: A turbine flowmeter comprises an impeller which has a rotary shaft rotatable together with the impeller and is provided within a flow passage through which a fluid to be measured flows, a pair of bearing members for axially supporting the rotary shaft, an oil accumulating part provided in a vicinity of the bearing member for holding a lubricating oil therein, and an oil supplying part for supplying the lubricating oil in the oil accumulating part in small quantities to at least one of the bearing members.

Abstract: An air compressor including a compressor unit, a drive unit for driving the compressor unit, a sound insulating box having an air inlet and an outlet and encasing the compressor and drive units, a fan positioned in the sound insulating box on the side of the air inlet for suctioning air thereinto, and a duct mounted in the sound insulating box. The duct has at one end opened toward the discharge side of the fan and the other end opened into at least one of the compressor and drive units where cooling is needed.

Abstract: A piston ring working in a cylinder and receiving a higher pressure on one axial side thereof than one the other and having axially overlapping stepped ends, wherein a circumferentially extending resilient lip is provided on one of the stepped ends of the low pressure side, and a circumferentially extending projection is provided on the other of the stepped ends of on the low pressure side and is located radially outwards of the lip to radially overlap therewith at least partially. In use, the lip resiliently deforms to engage with the projection in response to pressure acting on the radially inner surface of the piston ring.

Abstract: A vehicle height adjusting device includes a source of pressurized air, and an elevating device receiving the pressurized air from the source to change the overall length thereof, thereby changing the height of a vehicle. A drain separator is connected between the source of pressurized air and the elevating device, and an exhaust valve is connected to a drain port of the drain separator and selectively connects the drain separator with the atmosphere. A water collective filter element such as glass wool or the like is contained in the drain separator.

Abstract: A vehicle leveling system including a compressor, a leveler unit for lifting a vehicle body by compressed air from the compressor and an air dryer provided between filter casing filled with a filter element having moisture depositing function and a desiccant compartment filled with desiccant material. The filter casing is located on the side of the compressor while the desiccant compartment is located on the side of the leveler unit such that the filter casing has an area of air flow passage smaller than that of the desiccant compartment. The leveling system further includes a change-over valve which is connected to the air dryer on the side of the compressor to communicate the leveler unit selectively with either the compressor or atmosphere.
