摘要:
A vertical milling and turning machine generally comprises a spindle assembly connected to a drive motor. The spindle assembly comprises a hollow ram provided with a tapered opening at the front end thereof for attaching a turning tool and a hollow spindle provided with a tapered opening coaxial with the former opening at the front end of the spindle and the tapered opening of the spindle has a diameter smaller than that of the later opening. An air supply passage is formed in the ram so as to have an end opening opened towards the tapered opening of the ram and a detecting switch for detecting a pressure in the passage is connected to the air supply passage.

In order to provide a computer-to-plate (CTP) plate in which an image can be inscribed by a laser beam having Ithe maximum strength in a near infrared or infrared region, and heat processing is not necessary prior to developing a latent image, and which allows the use of a conventional printing apparatus as it is upon printing, (I) a lithographic printing plate is provided which has on a substrate, a photosensitive layer comprising a photosensitive composition containing a crosslinking agent, an aqueous dispersion of resin fine particles made of a resin which is self water-dispersible having a carboxylic group and a functional group capable of performing cross-linking reactions with the crosslinking agent, and an infrared absorption agent; and (II) an image forming method is provided which is characterized in that after an image has been formed on a photosensitive layer of the lithographic printing plate set forth in the above (I) by using a laser beam, the image is subjected to wet development.
摘要:
An epoxy resin laminate comprising a center base layer of glass fiber woven cloth and outer base layers of sheet-like material more expansible and compressible than glass fiber woven cloth provided on both faces of the center base layer and integrally impregnated with composite produced by reacting polybutadiene-acrylonitrile copolymer having carboxyl groups at its terminal with epoxy resin having more than two functional groups.
摘要:
A metal foil covered laminate comprising a sheet-like base formed of at least two of meta-aramid fiber, polyethylene terephthalate fiber and glass fiber and impregnated with epoxy resin including acrylonitrile/butadiene copolymer having terminal carboxyl groups and a metal foil covering on the sheet-like base.
摘要:
A liquid spray apparatus includes a liquid storage part storing a liquid, a vibratory source including a leading end, a recess being formed in a surface of the leading end, and a mesh member including a large number of micropores and arranged to abut on the surface of the leading end of the vibratory source. The liquid is supplied from the outside of the leading end to the surface and the recess of the leading end. The liquid supplied to the surface and the recess of the leading end is discharged in an atomized manner through the micropores by vibrations of the vibratory source. This liquid spray apparatus can stably spray the liquid with the vibratory source and the mesh member.
