摘要:
A method for producing a polarizing film includes (1) preparing a laminate (a) which includes a carrier film and a polarizer with a thickness of 10 μm or less formed on one surface of the carrier film and contains a polyvinyl alcohol-based resin; (2) peeling off the carrier film from the laminate (a); and (3) applying a liquid material to a side of the laminate (a) from which the carrier film has been peeled off and then solidifying or curing the liquid material to form a transparent resin layer with a thickness of 0.2 μm or more, wherein the liquid material contains a resin component or a curable component capable of forming a resin layer. This production method enables the achievement of a polarizing film which is able to have satisfactory durability in a heated environment even in cases where a thin polarizer is used therefor.

Embodiments of the present invention disclose a bended liquid crystal display and a manufacturing method and apparatus therefore. The method comprises: preparing an array substrate and a color filter substrate with flat glass sheets having different thermal expansion coefficients; applying adhesive sealant at edges of surfaces of the array substrate and/or the color filter substrate; heating the array substrate and the color filter substrate, and binding the expanded array substrate and color filter substrate together, to form an assembled substrate; and cooling the assembled substrate and forming a bended assembled substrate having a degree of curvature. The bended liquid crystal display has a better stability, and has no variation in its degree of curvature over service time.

摘要:
A rotational machining and quality assurance method for thermally extruded linings of turbomachinery are provided. First, a harder top coating is removed by turning, then the lining is finish-turned to size. During the finish-turning, defined turning parameters are maintained and a cutting force characteristic is quantitatively detected and stored. The force characteristic is compared with predetermined limit values, and, depending on the result of the comparison, the lining is approved for use or is produced again.

A tool holder for holding a cutting insert includes a head on which an insert-support surface is disposed. A plate is mounted on the head by a serrated connection, the head including fingers that form side surfaces disposed on opposing sides of the support surface. Each of the side surfaces includes a recess, wherein each side surface defines spaced apart contact areas. A slot extends through one of the fingers in spaced relationship to the side surface formed by that finger to render that side surface flexible. A passage interconnects an intermediate portion of that flexible side surface and an intermediate portion of the slot.

A cutting tool is disposed on a turret. The cutting tool includes: a holder having a peak end, and a throw-away insert clamped to the peak end of the holder with a clamp screw. The holder has a bottom face and a peak end face defining a corner of the holder. The corner of the holder forms a chamfered face. The throw-away insert has a bottom face and a relief face defining a corner of the throw-away insert. The corner of the throw-away insert forms a chamfered face. The chamfered face of the corner of the holder and the chamfered face of the corner of the throw-away insert prevent the cutting tools adjacent to each other from causing an interference with each other when the cutting tools are at least one of in a standby position and in a machining operation.
摘要:
A cutting tool assembly which includes a shank (1) and a removable cartridge (3) on which is mounted a cutting insert (5). The shank (1) is for mounting the assembly on a cutting machine. The cartridge (3) is removably mounted by a screw fastener (7) which passes through a hole in shank (1) into a threaded hole (31) in cartridge (3). The shank includes a recess (9) having sloping facing walls (15, 17) for engaging a complementary seating portion, having sloping walls (25, 27), of cartridge (3). The recess (9) and complementary seating portion of the cartridge are shaped such that the cartridge is wedged in the recess when the screw fastener (7) is tightened. The invention allows a reduction in costs by providing for the exchange of cartridges rather than a whole cutting tool. The wedging interconnection of the cartridge and shank ensures rigidity of the assembly. A modification is described wherein a recess for a screw fastener is provided instead of a hole (23) which allows for quick exchange of cartridges.

A modular cutting tool assembly inludes a tool holder having at least one insert receiving pocket, and at least two cutting inserts interchangeably receivable within the pocket. The pocket has a first lateral support surface forming an angle .theta. with a second lateral support surface as measured in a plane perpendicular to the pocket axis. Each of the cutting inserts has a peripheral flank surface configured to provide a number of abutment features appropriately angled for positioning in abutment with the lateral support surfaces. The peripheral flank surface of one cutting insert is further configured to provide at least two cutting points having a first nose angle, and the peripheral flank surface of the other cutting insert is further configured to provide at least two cutting points having a second nose angle different from the first nose angle.
摘要:
A lathe tool having a cylindrical shaft and a head with a contact surface which rests against a support surface on the shaft. The tool head is detachably connected in force-locking fashion by means of a fitted screw to the tool shaft. The contact surface and the support surface are disposed at an acute angle to the axis of the shaft and have mutually engaging straight tooth systems which extends over the whole cross-section of the shaft. The parallel teeth of the tooth system are perpendicular to the direction of slope of the support and contact surfaces and parallel to a surface disposed with its axis parallel to that of the tool head and including an indexable cutting insert.
