Abstract: PURPOSE:To speedily measure the distance from a piano wire to a mounting member of an elevator automatically with high accuracy without being influenced by the parallax or the width of said piano wire by providing a sensor part having a sensor confronting to said piano wire. CONSTITUTION:A gauge 2 is kept horizontal, with its one end pressed against a mounting member. Thereafter, a slide block 3 is moved along the gauge 2. When a sensor part 6 reaches a piano wire 1 as the slide block 3 slides, the light projected from a sensor is reflected, absorbed or interrupted by the piano wire 1. This change of the light indicates the presence of the piano wire 1. When the piano wire 1 is detected, a detector 5 is actuated, with generating sounds or light to inform the detection of the piano wire 1. After the slide block 3 is stopped, the gauge 2 is read by a reading part, so that the distance between the mounting member and piano wire 1 is measured. Thus, the distance between the piano wire and the mounting member of an elevator can be automatically and speedily measured with high accuracy without being influenced by the width of the piano wire.

Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To provide a high-frequency filter, having a good characteristic by changing the interval between the width of center conductors and grounded conductors in a resonator connecting part and/or an input/output connecting part and its neighborhood, while keeping the characteristic impedance of a resonator and/or an input/output line fixed. SOLUTION: The interval between the width of the center conductors 3 and 4 and the grounded conductors 2a and 2b is gently changed, so as to be wider in the neighborhood of the input/output-connecting part 6 and to be narrower in the neighborhood of the resonator-connecting part 5, while keeping the characteristic impedance of the line fixed. Therefore, the center conductors 3 and 4 are prevented from approaching more than necessary and influence on a passing characteristic from dimensional difference which becomes a problem in working is suppressed. In the resonator-connecting part 5, the interval between the end parts of the center conductor 3 is reduced, so that the filter is made small. Furthermore, fringing capacitance is reduced, that the passing characteristic deterioration from the difference in resonance frequencies in the resonator is suppressed.

Abstract: PURPOSE:To prevent malfunction due to a slight change in light quantity in a light-receiving element, by changing the driving time of a display lamp for displaying the signal level according to the size of the quantity of light received by the light-receiving element. CONSTITUTION:The pulse-modulated light from a light-projecting means 1 is supplied through a light-receiving element 2 and an amplifying circuit 3 to both a control circuit 4 and a display level discriminating circuit 11.

Moreover, a display lamp 9 displays the operating condition of the load 8. On the other hand, in the circuit 11, when the input voltage exceeds a discrimination level l2 to the negative side, an LED 13 is turned on only during the period W, and as the quantity of received light increases, the light-emitting period W is increased. Accordingly, when the optical axes of the light-projecting means 1 and the light-receiving element 2 respectively coincide with each other, the luminance of the LED 13 becomes maximum, and the regulation of the optical axes is completed.
