Title: Mixing of fine particles
Inventor: KONDO JIRO
IPC: B01F3/18
Filed: 1991-04-04
Abstract: PURPOSE:To permit at least two kinds of powders to be homogeneously intermixed at a uniform level of the particle size by passing at least two kinds of the powders through a mixing cylinder having a high frequency moisture applied thereto so as to be mixed together. CONSTITUTION:Raw powders 3 and 4 are fed from two powder feeders 1 and 2, respectively, and dropped into a mixing cylinder 5. A high frequency vibrator 7 is excited by the high frequency moisture produced by a high frequency generator 6 into a high frequency vibration, which is then transmitted through a vibration transmitting horn 8 to a mixing cylinder 5, and then the raw powders therein receive the high frequency vibration and move about and apart with an extremely active motion. As a result of this movement, the two kinds of raw powders 3 and 4 become homogeneously intermixed fine particles 9, which are then discharged from an outlet of the mixing cylinder 5 as a stream 10 of a homogeneous powder mixture. The mixing cylinder 5 is required to be of such a length as to permit the powders to be intermixed homogeneously and prevent the powders from overflowing to the outside and its length is usually made equal to or greater than its diameter.

Filed: 1985-05-09
Abstract: PURPOSE:To maintain high volumetric and adiabatic efficiencies regardless of varied flow rates by employing a means for changing volume of a space formed between a piston and a cylinder. CONSTITUTION:When a setting value Gs of a flow rate G of a fluid is raised in an attempt to raise the flow rate of a compressible fluid, a control device 81 increases heating amount of operation fluid at a heater 46 through a cable 82.

Title: Welding method for parallelly joined alloy bars
Inventor: MINAKI YOSHIHIRO
IPC: B23K26/21
Filed: 1988-04-21
Abstract: PURPOSE:To prevent the occurrence of undercuts by inclining both bar materials in the cross direction so that bar material with the higher extent of undercuts comes to the lower side. CONSTITUTION:When dissimilar materials such as parallelly joined bimetals are welded, for instance, both bar materials are abutted on each other so that stainless steel bar material 2 on which the undercuts are liable to take place comes to the lower side of 'Invar(R)' alloy bar material 1 and welding is performed. At this time, both bar materials 1 and 2 are inclined by an angle alphaand an electron beam 4 is struck vertically against both bar materials 1 and 2 to perform welding. As a result, when being solidified, weld metal is pulled to the 'Invar(R)' alloy 8 side and the undercuts taking place on the stainless steel 7 side is pulled to the stainless steel 7 side by gravity and can be prevented from taking place. Accordingly, cracking by press working is eliminated and parallelly joined alloys with functionally high reliability are obtained.

In the die, the slot gap of which is constant crosswise, the flow rate at the side of the slot is reduced by narrowing the packing 6 on the slot outlet side or widening the slot outlet width so as to prevent the generation of thick film at the side part of cast film. Or in the die, the width of each side packing of which is constant, the generation of thick film at the side part of cast film is prevented from occurring by making the slot gap at the side smaller than that at the center of the width of the slot. In other words, the discharge rate per unit length near the side edge is made to be smaller than the average dis charge rate at the center of the width of the slot.
