Disclosed is a cable adaptor comprising a first member which is conductive and comes into contact with a signal pin of the cable, a second member disposed outside the first member and coupled to the first member, a third member which is conductive and disposed outside the second member, and a contact pin fixed to the first member. Here, the first member includes a first body coupled to the second member and a first contact portion which extends from the first body and comes into contact with the signal pin. The third member includes a second body coupled to the second member and a second contact portion which extends from the second body and comes into contact with the outer conductor. A plurality of first contact points of the signal pin and the first contact portion are arranged at same intervals along a circumferential direction of the signal pin.

Cable adaptor coaxially connected to an outer conductor and signal line of a cable

Disclosed is a cable adaptor which is connected to a cable including an outer conductor. The adaptor includes a contact pin which comes into contact with a signal pin of the cable, a first member which is conductive and disposed inside and coupled to the contact pin, a second member disposed outside and coupled to the contact pin, and a third member which is conductive and disposed outside the second member. Here, the contact pin includes a first body coupled to the second member, a first contact portion which is conductive and extends from one side of the first body to come into contact with the signal pin, and a second contact portion which extends from the other side of the first body and comes into contact with an object being tested. The third member includes a second body coupled to the second member and a third contact portion.

Cable adaptor

Disclosed is a method for preparing a solid catalyst for propylene polymerization, and more specifically, a method for preparing a solid catalyst for propylene polymerization including (1) first reacting dialkoxy magnesium and titanium halide compound under the presence of an organic solvent; (2) adding two kinds of non-aromatic internal electron donors to a product of the step (1) and reacting the mixture; and (3) second reacting the product of the step (2) with a titanium halide compound and washing a reaction product. The catalyst prepared according to the method as described in the present disclosure not only may provide high catalytic activity, but also may provide a propylene polymer having excellent stereoregularity.

Preparation method of solid catalyst for propylene polymerization

The present invention includes: a main body which defines a storage space in the lengthwise direction, and in which a plurality of biosensors can be stacked; a cover member covering one end of the storage space and including a discharge hole through which only one biosensor located at the outermost edge of the stacked biosensors can pass; and a cover coupled to the cover member in order to be raised and lowered so as to open and close the discharge hole. The discharge hole is closed such that the biosensors stacked in the storage space are not contaminated and the infiltration of impurities into the storage space is prevented, and the discharge hole is temporarily opened when the biosensors are to be used in order to withdraw the biosensors.
