摘要： The present invention relates to a linear displacement transducer with improved accuracy, in which stable contact is achieved by forming contacts coming into contact with resistors in a elastic linear contact type, rather than a conventional point contact type, using a rotating roller made of a conductive rubber material, and the life span thereof is extended by considerably reducing friction. The linear displacement transducer with improved accuracy, in which the displacement of an object is measured depending on resistance values measured on contacts in contact with a thin film A having a zero electrical resistance value and a thin film B having an electrical resistance value RL and being parallel to the thin film A, includes a conductive rotating roller connected to one end of a moving shaft, adapted to rotate in conjunction with the movement of the object and configured to form linear contacts while being in contact with the thin films A and B, and the average of electrical resistance values, which are generated by the linear contacts formed by the rotation of the rotating roller, is measured as displacement.

摘要： Disclosed is a screen-type spirometer having an improved pneumotachometer, which has a simple structure and a low manufacturing cost and is convenient to use. According to the present invention, the pneumotachometer includes a hollow housing having an annularly shaped ring and a first respiratory tube integrally formed with the annularly shaped ring. The first respiratory tube can be inserted into a mouth of a person to be examined. The pneumotachometer also includes a second respiratory tube which can be engaged with the housing and be inserted into the mouth of the person. The first and the second respiratory tubes have a tapered portion, which is inclined at 10 degrees, respectively in order to stabilize a fluid flow of respiratory gases passing therethrough. O-shaped first and second sensing units for sensing a differential pressure of the respiratory gases passing through the pneumotachometer are disposed within the housing. A circularly shaped screen operating as a mechanical resistance against the respiratory gases is disposed between the first sensing unit and the second sensing unit within the housing. Prepherably, a suitable size for the screen has been found to be in the range of a screen having a mesh of 300 openings per inch. The pneumotachometer comprises a blowing apparatus for drying and cleaning the screen at need. The blowing apparatus is provided as an individual unit. A handle is attached to an outer surface of the annularly shaped ring.
