Title: Production of leaf-plate-shape hinge
Inventor: YAMAKAWA TATATOMI
IPC: B21K13/02
Filed: 1979-11-12
Abstract: PURPOSE: To produce a plurality of hinges through one face-pressing forging by applying face-pressing forging to the partial striplike face area over a width direction of a flat plate material from its front and back to cause material movement, extrusion-molding the bulged parts for working shaft cylinder and blaking these away.  
     CONSTITUTION: Right and left plate parts of a flat plate material 10 are grasped by means of two sets of clamping upper dies 12, 12' and clamping lower dies 13, 13', and the material is subjected to repetitive face-pressing forging from the top and bottom sides by means of the punches 14 disposed between the dies. This causes material movement from the face-pressing forged area P 1  into the extruded die parts 12b, 13b, whereby two sets of bulged parts 11b for working shaft cylinders are extrusion-molded in the end part face areas P 2  of the leaf plates 11a contacting right and left. When these are blanked away, two sheets of hinge blank materials having the bulged parts 11b for working shaft cylinders at the end parts of the leaf plates 11a are obtained. Shaft insertion through-holes are pierced in the bulged parts 11b for working shaft cylinders of these hinge blank materials, whereby the leaf-plate-shape hinges are obtained.

Abstract: PURPOSE:To increase the capacity to cool a polarizing plate by providing a cooling tank and radiator for which a liquid refrigerant is used in contact with the polarizing plate. CONSTITUTION:The light emitted from a light source 201 transmits the polarizing plate 250 and is subjected to optical intensity modulation and wavelength modulation by a light valve 217 provided with color filters formed to a mosaic shape for each picture element. After this light is transmitted through the 2nd polarizing plate 220, the light is projected onto a screen 233 by a projecting lens 231. The cooling tank 292 in which freon 291 is sealed as the liquid refrigerant is disposed to the polarizing plate 250 in contact therewith and the radiator 293 is mounted around the cooling tank. The polarizing plate 250 is cooled by using the liquid refrigerant 291 for cooling the polarizing plate 250 and bringing the polarizing plate 250 into contact with the liquid refrigerant tank 292; further, the heat of the liquid refrigerant 291 is radiated from the radiator 293 which is increased in the radiation area constituting a part of the liquid refrigerant tank 292 as compared to the polarizing plate 250. The efficiency of the cooling is improved in this way.
