This invention relates to a chlorine-containing resin molding characterized by its stabilization by aminocarboxylic acid and from which molding substantially no metallic ion is detected, and to material for use with the chlorine-containing resin molding consisting of 100 parts by weight of chlorine-containing resin and 0.5-5.0 parts by weight of aminocarbolyxic acid. According to the molding and the material for use therewith, there is no possibility of metallic ion dissolving from the molding in which a metallic stabilizer is conventionally used, with the result that the molding finds wide application in the industrial field related with electric parts including a semiconductor as a main item, medical treatment, chemicals and pharmaceuticals, and food stuffs, all subject to adverse effects by dissolution of metallic ion. Consideration for application of a nonmetallic agent is also given to the use of a coloring agent and a lubricant with respect to the molding and the material for use therewith.

摘要:
An electro-optical probe used for an oscilloscope (e.g., electro-optic sampling oscilloscope) is mainly constructed by a probe head and a probe unit. The probe head contains a metal pin and an electro-optical element having a reflector at its terminal surface. The probe unit contains a reduced number of optical parts, which are arranged such that an optical axis of incoming beams of the electro-optical element differs from a optical axis of outgoing beams of the electro-optical element. That is, laser beams output form a laser diode are subjected to convergence by a converging lens to produce converged beams, which are incident on the electro-optical element as its incoming beams. The incoming beams are subjected to reflection by the reflector to produce reflected beams, which are output from the electro-optical element as its outgoing beams. Then, the reflected beams are converted to parallel beams by a collimator lens, or they are converged by a converging lens. A polarization detector performs separation on input beams from the lens to produce separated components of beams, optical axes of which differ from each other. Those components of beams are respectively supplied to photodiodes, wherein they are converted to electric signals. Thus, it is possible to measure a waveform of a measured signal based on differences between the electric signals, which reflect changes of polarization states of the beams in the electro-optical element.
