Title: Die cushion apparatus in press
Inventor: KURISHIMA KENJI
IPC: B30B15/02
Filed: 1989-08-07
Abstract: PURPOSE:To deal with high velocity operation in a press by providing a capacity detector for a die cushion, a detecting means for number of strokes in the press, a control valve and this control means and a storing means for opening/ closing mode in a rocking release valve. CONSTITUTION:Timing opening the rocking release valve 41 corresponding to the die cushion capacity and spm (number of strokes per unit time) is pre- stored in the storing means. At the time of detecting above capacity and spm with a pressure sensor 19 and stroke detecting means as the capacity detector for detecting the die cushion capacity, the timing data corresponding to these in the storing means are read out and according with the data, the control valve 50 is changed over. Even in the case of changing to low die cushion, as the raising timing of die cushion is quickened according with this, the press can deal with the high velocity operation. Further, even in the case of changing to low spm, as the raising timing comes to slow, this can deal with the condition without any trouble.

Title: Veneer lathe
Inventor: WATANABE KENZO
IPC: B27L5/02
Filed: 1998-07-02
Abstract: PROBLEM TO BE SOLVED: To prevent the indisposed cutting ability and lowering of yield from occurring by the cutting into pieces of a log due to cracks by a method wherein a cutting knife abuts against the outer periphery of the log at the upper side in the direction of rotation of the log and a rotatingly driven rotator presses the outer periphery of the log at the upper side in the direction of rotation of the log. SOLUTION: At the starting of cutting, under the condition that the piston rod of an air cylinder is retreated and both the edge faces of a log 12 are supported with spindles, the log 1 is rotated so that the peripheral speed of the log 1 is run slower than that of a roller bar 9 by a predetermined value, resulting in controlling the amount of the advancement per one rotation of the log 1 to a plane stock 4. A cutting knife 2 and the roller bar 9 abut against the peripheral surface of the log 1, resulting in cutting the log 1 with the cutting knife 2 by means of the force F1 of the roller bar 9 and the forces of the spindles so as to obtain a veneer T intermittently.  When the unevenness of the peripheral surface of the log 1 is annulled through the continuation of cutting of the log 1 and consequently a continuous band-like veneer T is obtained, the piston rod of the air cylinder is advanced manually by an operator. Thus, even when the log 1 has cracks, the cutting of the log can be performed without widening the cracks with pressers 9 and 24, resulting in allowing to raise the yield of a veneer T to be obtained.

IPC: H01F7/16
Filed: 1985-09-18
Abstract: PURPOSE:To increase magnetic force which actuates a movable element with permeance of a magnetic path increased, by including magnetic fluid between a stator and the movable element in a solenoid device, in which the movable element is driven by making the magnetic force act between the stator and the movable element. CONSTITUTION:A pipe 9 made of elastic material is inserted into holes 5a and 3a of a front frame 5 and a bobbin 3, with its right end part closely fitted to a stator iron core 11. And a movable iron core 6 is inserted into the pipe 9 and then magnetic fluid 10 is included therein. Packing 12 made of elastic material for preventing the magnetic fluid 10 from leaking is fixed at the left end of the pipe 9. Fluid, for example, in which powdered triiron tetroxide is covered with oleic acid and dissolved in solvent of poly-<alpha>-olefine, is used as the magnetic fluid 10. Because of inclusion of the magnetic fluid remarkably higher in permeability than air, permeance (induced magnetization rate) of the magnetic path between the stator and the movable element becomes in creased regardless of stroke amount of the movable element, and therefore magnetic force acting between the stator and the movable element becomes increased.

IPC: C22B9/04
Filed: 1993-07-26
Abstract: PURPOSE:To provide an apparatus and a method for refining an aluminum alloy containing metallic impurities having higher vaporizing pressures than aluminum, such as Zn, Mg. CONSTITUTION:The molten aluminum alloy 1 containing the metallic impurities enabling the vaporization and having comparatively high vaporizing pressures is dispersed as grains by blowing high temp. inert gas in a high temp. reduced pressure treating vessel 3. The dispersed granular molten materials 9 are exposed to the inert gas-flowing reduced pressure. The metallic impurities in the molten metal is vaporized because the molten material 1 is exposed to the high temp. and the reduced pressure in the granular state having the large surface area. Further, the vapor of the metallic impurities around the granular molten metal is removed from the surroundings of the granular molten metal by the flow of the inert gas, and the partial pressure of the metallic impurities around the granular molten metal is lowered. Therefore, the metallic impurities having high vapor pressure in the molten aluminum alloy are rapidly vaporized and removed.

Title: Belt-type stepless speed change gear
Inventor: ONOUE SUSUMU
IPC: F16H9/12
Filed: 1982-11-22
Abstract: PURPOSE:To stably obtain high transmission capability and to improve durability by providing a V-belt, pitch lines of which are different between a fixed sheave side and a movable sheave side to produce a difference in peripheral speed at both sides, thereby working trust more effectively. CONSTITUTION:In the case where a speed change pulley having an automatic pressing mechanism is on drive side, the side angle theta1 of a belt on fixed sheave side is set larger than the angle theta2 on movable sheave side. Therefore, the turning force generated by usual slip is converted to lateral thrust by a spiral key 5, so that the shave thrust is improved, and belt slip opposite to belt running caused by a difference in peripheral speed between both sheaves 1, 2 is added to the sheave thrust to be further improve. Thus, the thrust by the automatic pressing mechanism works effectively to stably obtain high transmission capability, and as the thrust is stable, excessive force will not work upon the V-belt to improve durability.

Title: Core of heating rollers for copying machine and preparation thereof
Inventor: TAKUMI HIROTAKA
IPC: B24B5/37
Filed: 1983-11-01
Abstract: PURPOSE:To prevent the bending of a core and improve close adhesion strength by press-attaching a disc-shaped grinding member in high-speed revolution, onto a cylindrical core member which shifts in the axial direction so that the both axes cross at right angles and forming a number of thin grooves in the axial direction onto the outer peripheral surface of the core. CONSTITUTION:On the opposite side to a grinding member 2 with respect to a cylindrical member 1, a pair of feeding rollers 3 and 3' are press-attached onto the member 1, and the shaft of one feeding roller 3 is set in parallel to the axis of the member 1, and the shaft of the other roller 3' is not set in parallel to form an angle and press-attached onto the member 1. When a pair of rollers 3 and 3' are revolved together with the grinding member 2 revolving at high speed, the member 1 shifts in the axial direction in revolution and compulsorily fed into the under part of the grinding member 2, and thin grooves are formed in the axial direction onto the outer peripheral surface of the member 1. Since the revolution of the grinding member 2 is higher than the feeding speed of the member 1, a rectilinear groove is formed onto the outer peripheral surface in actuality. Since an intensive impact as in sand blasting method is not generated, a core is hardly bent, and close-adhesion strength can be kept.
