Filed: 1980-12-10
Abstract: PURPOSE: To reduce power consumption of a screw compressor by dividing a discharge side pipe passage into two, the first pipe passage having a check valve which feeds discharge air to an after-cooler and the second pipe passage having an ejector enabling the pressure of discharged air below the level of atmospheric pressure and a sluice valve.  
     CONSTITUTION: A discharge side pipe passage of a screw compressor 2 is divided into two, the first discharge side pipe which feeds discharge air to an after- cooler 5 having a check valve 4 and the second discharge side pipe passage 2c having an ejector 8 enabling the pressure of discharged air below the level of atmospheric pressure and a sluice valve 6. With this arrangement, at an unload time when a suction throttle valve 3 is fully opened while the sluice valve 6 is fully closed, an air in the first discharge pipe passage 2b is introduced into a tank 7 and is pushed out by the ejector 8, whereby the pressure before and behind the compressor 2 becomes below the level of atmospheric pressure so that it 2 does not compress the air. Consequently, the power consumption of the compressor 2 at its unload operation can be reduced.

Title: Screw tap
Inventor: FUJII YUKIO
IPC: B23G5/06
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To prevent a remained part of a tap from being buried in a female screw when not less than the predetermined shearing stress is applied to the tap by setting a shearing part for allowing the shearing stress to be concentrated thereto, on one of shank parts. SOLUTION: A shear groove (a) is formed on a shank part 2 to concentrate the shearing stress on a part of this groove (a). Accordingly, by forming the shear groove (a) on the shank part 2, the shank part 2 from a threaded part 1 to the shear groove (a) is necessarily projected from a female screw during the formation, even though a screw tap is sheared from the shear groove (a). As a part of the shank part 2 is projected to the outside of the female screw during the formation, the projection can be forcibly turned by gripping the projection by a cutting pliers or the like. Accordingly by turning the projection in the direction opposite to the thread cutting direction, a residue remained in the female screw during the formation can be removed.

Title: Production of gold alloy wire
Inventor: SAWADA KAZUO
IPC: B22D11/01
Filed: 1984-08-22
Abstract: PURPOSE:To draw directly a fine gold alloy wire from a molten gold alloy and improve yield of the product thereof by ejecting the melt of the gold alloy added with a limited weight ratio of Be through a fine hole or slit and solidifying the melt in fluid. CONSTITUTION:The molten gold alloy added with 0.001-1wt% Be is used, by which the viscosity, surface tension and surface oxidation condition of the melt and the wettability with a nozzle are changed and the jet flow of the molten gold alloy is stabilized. The reason for limiting the weight ratio lies in that the molten gold alloy is liable to granulate and that the continuous and uniform production of the wire is difficult if the ratio is <=0.001wt%. On the other hand, the characteristic and uniformity owing to an increase in the Be content are of problem while the effect of stabilizing the molten flow is satd. if the ratio is >=1wt%. Various kinds of fluid in addition to water are usable for the fluid.
