摘要:
A sheet-testing apparatus including kneading rolls, a frame feeder, sheet applicator, foreign material detector, a frame with a light transparent window and a cutter for cutting a sheet. A sheet-testing sample-making apparatus has a cluster of kneading rolls, frame feeder, and sheet applicator. A sheet thickness detection apparatus outputs an electric signal to a memory. A kneading apparatus has a pair of heating rolls separated by a gap. The directions and speeds of rotations of the rolls are adjustable. A sensor detects the gap and a bank sensor detects the condition of a bank in the gap. The distance between the rolls, their temperatures, rotations, and speeds are automatically controlled. A pair of blades peel a sheet from the sheet-winding roll. Material dropped through the gap between the heating rolls is returned to a point above the gap. A cutting device has a length of wire sprung onto a rolled sheet to sever the sheet. A heating roll cleaning device brings cleaning rolls into sliding engagement with the heating rolls. A heating roll cleaning device feeds an elongated cloth-like cleaning member for cleaning heating rolls.

The method of the invention includes a step of jointing, in a sheet formed in a rectangular shape, end portions of a pair of mutually opposed two sides in such a manner as to form a jointed portion of a predetermined width along a planar direction of the sheet. In the rectangular sheet 1, a pair of mutually opposed two end portions 4, 5 are jointed by a joint portion formed along the planar direction of the sheet.

A color cathode-ray tube includes an antireflection layer and a black matrix layer on the inner surface of a face plate thereof. The antireflection layer contains SiO.sub.2 fine particles and is deposited on the inner surface of the face plate without being interposed between the face plate and the black matrix layer.

A cathode ray tube has a vacuum envelope formed of a panel portion supporting a phosphor film on an inner surface thereof, a neck housing an electron gun, a funnel joining the panel and the neck, and a stem sealing an open end of the neck and mounting the electron gun via a plurality of pins extending through the stem. The inside diameters at the open end sealed by the stem and vicinities thereof become gradually larger toward the open end sealed by the stem, or retain at least a value substantially equal to an inside diameter of a major portion of the neck.

摘要:
The present invention relates to improvements in a substrate for producing an electrophotographic sensitive member having a photoconductive layer formed with amorphous silicon. An electrophotographic sensitive member, which is superior in moldability, corrosion resistance, strength, charging electric potential and the like, is formed when an aluminium material, which contains at least one of iron and manganese or a combination of each at 0.30 or less % by weight, is used as a substrate on which a photoconductive layer formed with amorphous silicon is laminated; and/or the surface roughness of said substrate is 0.5 S or less; and/or an aluminium substrate containing magnesium at 0.5 to 10.0% by weight is used.
