Title: Method and apparatus for extrusion-molding cylindrical body increasing partial thickness thereof
Inventor: SHIMONO SEIICHI
IPC: B29C48/13
Filed: 1980-05-07
Abstract: PURPOSE:To mold continuously a cylindrical body by extrusion in which the thickness is increased locally and clearly at desired positions by a method wherein the sectional shape of a core bar is expanded or contracted directly during forming, and forming clearances are changed to adjust the thickness of a product. CONSTITUTION:Pressure oil or compressed air is supplied from a pipe 17 into a cylinder 12 via a through hole 16 and the cylinder 12 is pushed backward to compress an elastic body 13 through a cover plate 12a. The elastic body 13 is reduced in length and increased in diameter to contract the forming clearance 14. Resin 18 passes through an arm 9b and a cylindrical body of thickness t0 is molded continuously. When the pressure oil or compressed air in the cyinder 12 is removed through the pipe 17 to release the pressure in the cylinder, the elastic body 13 pushes the cylinder forward and returns to the original shape by its own stability and the frictional force of the resin 18. The molding clearance 14 is expanded and the cylindrical body of tickness t1 is molded continuously.

Title: Driving device using electromechanical transducer element
Inventor: YOSHIDA RYUICHI
IPC: H02N2/00
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To provide a driving device using an electromechanical transducer element, in which the frictional force of a frictional coupling section is adjusted in response to the fluctuation of load, and which can be driven with high driving efficiency at all times. SOLUTION: In the driving device, in which a slider block is coupled frictionally with a driving shaft reciprocated and vibrated by displacement by the expansion and contraction of a piezoelectric element, frictional force is adjusted in response to the fluctuation of load. Frictional force between the slider block and the driving shaft is altered periodically at that time (P1). The amplitude of a speed change and a specified level are compared (P2), and treatment is completed when the amplitude of the speed change does not exceed the specified level. When the amplitude of the speed change exceeds the specified level, displacement between the phase of the fluctuation of driving speed and the phase of the fluctuation of frictional force is decided (P3). Mean frictional force is adjusted at a large value when a phase shift is 0 deg.  (P4), and mean frictional force is adjusted at a small value when the phase shift is 180 deg. (P5). Accordingly, the amplitude of the fluctuation of driving speed can be reduced when frictional force is adjusted in response to the fluctuation of load, and the driving device can be driven with high driving efficiency.

Abstract: PURPOSE:To maintain uniformly the plating deposition in a transverse direction by measuring the plating deposition, etc. at the transverse points corresponding to each of plural electrodes and controlling independently the plating current of the electrodes so that the measured values attain the common target value. CONSTITUTION:The electrode 1 is formed of the divided electrodes 11, 12, 12'-19, 19' which are divided in the transverse direction and are insulated. These electrodes are connected electrically to current control devices 21-29. The current of the same value is passed to the divided electrodes 12'-19' in the symmetrical positions as well. The coating weight or plating current density in the transverse direction of a strip is actually measured, upon starting of plating, in accordance with the positions of the electrodes 11-19 or 11-19'. The ratios between the actually measured values and the coating weight in the central part in the transverse direction corresponding to the electrode 11 are determined and are fed back to the coating weight control device. The current controlled variable in the transverse direction is calculated by said control device and commands are emitted to the devices 21-29 so that the current values in the electrodes 12-19' attain the intended set values. Each coating weight in the transverse direction of the strip is thereby made to coincide with the target value.

Abstract: PROBLEM TO BE SOLVED: To produce a thin hot-rolled steel sheet at a low cost and in high yield by using a direct feeding rolling technique connecting a continuous casting with a hot-rolling and directly rolling a slab having the length exceeding the furnace length of a hot-rolling slab reheating furnace. SOLUTION: The slab having the length exceeding the furnace length of the slab reheating furnace for the slab produced with the continuous caster 1 is carried to a rougher rolling mill 3 in the hot-rolling process and the blank rolled to a prescribed thickness is wound as a coil-state in a coil box 4 and stayed in a fixed time and the whole blank is heated with the returned heat. The blank is straightened in a leveller 5, and after heating to the Ar3 transformation temp. or higher with a blank heating device 6, the blank is rolled with a finish rolling mill 9. In such a way, since the continuous casting and the hot-rolling are directly connected, the reheating furnace is unnecessary, and the slab having the length exceeding the furnace length of the reheating furnace can be rolled.  Since the length at the tip part of the steel sheet producing defective shape is not changed, the effective length is lengthened and the improvement of the yield can be obtd.
