    摘要: A signal detecting apparatus is to obtain hysteresis characteristic at a constant ratio regardless of signal amplitude fluctuations by supplying the threshold level adjusting signal corresponding to the input signal amplitude to the comparison circuit. The threshold value setting signal and the hysteresis adjusting signal is supplied to a comparison circuit through an amplifier and a hysteresis adjusting means having the identical characteristic with the peak hold circuit to set a threshold value and a hysteresis range. Therefore even in the case where the operating characteristic of the amplifier and the peak hold circuit for detecting the peak level of signal amplitude fluctuate, the threshold value and the hysteresis range fluctuation corresponding to the fluctuation. As a result, there can not need the adjustment for resetting the operating characteristic, the threshold value and the hysteresis range in each circuit and thus the time and labor required for adjustment can be further saved.

    摘要: An apparatus for machining a bevel gear has an apparatus frame, a spindle head provided on the apparatus frame for rotatably supporting a spindle on which a machining tool is mounted, and an indexing unit provided for holding a workpiece such that the workpiece is indexed by one pitch of teeth to be formed thereon to perform machining of tooth spaces with the machining tool. The spindle is horizontally and rotatably held on a spindle head such that the spindle is immovable in the axial direction of the spindle. The spindle head is movable back and forth in the axial direction and is movable in a lateral direction at right angles to the axial line. A column is provided on the apparatus frame in front of the spindle head such that the column is turnable about a vertical axial line at an arbitrary angle. The indexing unit is provided in a plurality of pieces on an external periphery of the column at a distance between each of the indexing units. The indexing units are provided on the column in a vertically movable manner. A plurality of vertically movable lifting frames are provided on the column at a distance therebetween in the circumferential direction of the column and the indexing units are detachably mounted on the column.

    摘要: The present invention provides a device and method for analyzing the characteristics of a biopolymer with excellent mechanical stability, high spatial resolution and sensitivity using a simple device construction. Specifically, the Raman scattered light of a biopolymer is measured and the properties of monomer units forming the biopolymer are analyzed by using a biopolymer property analysis chip (100a) characterized by comprising: a solid substrate (110); at least one nanopore (120) disposed in the solid substrate (110); and one or more electrically conductive thin films (130a, 130b) disposed on the solid substrate (110). The biopolymer property analysis chip (100a) is characterized in that the electrically conductive thin films (130a, 130b) are disposed partially on the solid substrate (110) where the nanopore (120) is formed and a biopolymer which has penetrated into the nanopore (120) is caused to generate Raman scattered light by means of irradiation with external light.
