Analog quantity display method, analog quantity measuring method, and digital/analog display type measuring instrument

The present invention provides an analog quantity display method of counting displacement of a probe disposed in contact with an object to be measured and analog-displaying the obtained count value by an analog display section as an analog quantity. If a peak value of the count value exceeds a possible analog-display range of the analog display section, an offset provided for the analog-displayed count value is updated in such a manner that the peak value is displayed within the possible analog-display range. Further, an analog quantity measuring method is provided, which comprises counting displacement of the probe, compares the obtained count value with a peak value of the count value, holds the count value as a new peak value depending upon a result of the comparison, and executes the comparison and the holding of the peak value again if the difference between the present peak value and the present count value exceeds a predetermined value. The analog quantity display and measuring methods are applicable to a digital/analog display type measuring instrument comprising a counter for counting the displacement of the probe in contact with the measured object, a digital display section for digitally displaying the count value, and an analog display section located adjacent to the digital display section, for displaying the count value as the bar graph comprising the large number of analog bars arranged in juxtaposition in one direction.

Sleeper synthesized by enhanced fiber

The invention relates to a reinforced fiber composite sleeper for supporting railway tracks. The reinforced fiber composite sleeper is one made from reinforced fiber materials, fiber felts or weaving cloth through resin impregnation, formed by the pultrusion of a forming die for designing the shape of the section and solidified in the forming die. The invention overcomes the defects of the known techniques, has ideal strength and elasticity and good insulating property compared with the common concrete sleeper and the anticorrosive wooden sleeper, and ensures the safe running of the trains. In addition, with the good elasticity, the reinforced fiber composite sleeper greatly enhances the whole elasticity of the track structure and reduces the influence on roadbeds from the vibration of the trains and the environmental pollution from the noise of the trains during running; with the good insulating property, the reinforced fiber composite sleeper has no influence on the track circuits so as to ensure the safe running of the trains. The invention has the advantages of simple manufacturing, easy forming and short production period, and is capable of realizing the mechanical and continuous production. Besides, the length of the reinforced fiber composite sleeper can be cut and processed according to the determined length requirements, and the waste sleepers can be treated and recycled easily.

Urban rail transit shock absorption type floating slab rail system

An urban rail transit shock absorption type floating slab rail system comprises a floating plate (1), a tunnel foundation (5) and a steel rail (2). The steel rail (2) is fixed to the floating plate (1) through fasteners (3). The floating plate (1) is arranged on the tunnel foundation (5) through a vibration isolator (4). The tunnel foundation is arranged in a tunnel (8). The urban rail transit shock absorption type floating slab rail system further comprises a shock absorption device arranged on the floating plate (1), The shock absorption device is composed of shock absorption blocks (6) or shock absorption strips (10) and an elastic damping element (7) and is arranged on the floating plate (1) discretely. Some lines of the shock absorption blocks (6) are arranged within the width range of the floating plate (1), and the other shock absorption blocks (6) are arranged within the length range of the floating plate (1). The urban rail transit shock absorption type floating slab rail system is simple in structure and convenient and feasible to assemble and detach; the low-frequency-band vibration isolation effect of the floating plate is improved, the disadvantageous influence that vibration is amplified when the frequency of the floating plate is close to the inherent frequency is restrained, and the urban rail transit shock absorption and noise reduction control and the social harmonious development promotion are facilitated.
