摘要:
A process for production of a composite porous film wherein a porous support, of which both sides have been coated with a solution (dope) of an organic polymer compound in a water-soluble organic solvent to form a coated film, is passed through an air gap step and conveyed into a coagulating bath comprising water or a mixture of water with the same solvent as the organic solvent, and is then immersed in the coagulating bath so that the coated film on both surfaces of the porous support directly contact the coagulating bath for coagulation, and is then washed and dried. This production process is suitable for production of non-aqueous secondary battery separators, and yields non-aqueous secondary battery separators with good handling properties and at low cost, whereby the ion permeability, adhesion with electrodes and electrolyte solution retention can be strictly controlled.

This magnetic recording medium has a substrate, a nonmagnetic granular layer formed above the substrate and a recording layer formed on the nonmagnetic granular layer. The nonmagnetic granular layer is made of CoCr alloy with an hcp or an fcc crystal structure in which a nonmagnetic material segregates virtually-columnar magnetic grains. The magnetic recording medium and the magnetic storage apparatus in which the medium is used have improved reading/writing performances.

Provided is a technique to connect connectors that electrically connect coaxial cables to each other, the technique capable of reducing errors in manual work and improving work efficiency by making the work easier and simpler. Plural slots 123 each extending in an axial direction are provided in a base-end-side supporting region α of an outer conductor 12 of a contact-section portion 14. Base-end-side supporting pieces 124 deformable radially are formed by the slots. The base-end-side supporting region of the contact-section portion is attached to the inside of a supporting tubular portion 171 of a housing 17, and thereby a leading-end-side un-supported region β that is not supported by the housing is allowed to incline with respect to the axial direction.
