Filed: 1983-01-17
Abstract: PURPOSE:To obtain a permanent magnet which is small in magnetic fluctuation with a temperature change and is not lowered in coercive force even in a compaction treatment, by a method wherein particles of a porous aluminum oxide filled in its pores with a ferromagnetic metal or ferromagnetic alloy are compression-molded in a magnetic field and hardened. CONSTITUTION:An aluminum or aluminum-base alloy substrate is anodized to form a porous aluminum oxide film 6. A ferromagnetic metal or ferromagnetic alloy is desposited in the pores of the film by electroplating. This is finely ground to obtain a magnetic powder 4. Each ferromagnetic body 5 in the magnetic powder 4 has a diameter of about 0.01-0.04mum and a length of 0.1-1mum. The ferromagnetic bodies 5 are filled while aligning in one direction and are coated with the aluminum oxide 6. The magnetic powder 4 is compression- molded in a magnetic field and hardened to form a permanent magnet. In this case, the pressurizing direction and the magnetic field direction are made orthogonal to each other to obtain excellent magnetic characteristics. Further, a liquid organic resin is employed as an impregnating binder. The impregnation is carried out at an ordinary temperature or properly raised temperature and in the atmospheric air or under high-pressure conditions.

Title: Lubrication stopper
Inventor: OZAWA MASAAKI
IPC: F04B37/16
Filed: 1983-01-18
Abstract: PURPOSE:To make the proper amount of lubricating oil maintainable all the time as well as to prevent a vane or the like from a breakdown accident, by installing an oil separator which recovers a discharged outflow portion of the lubricating oil from a vacuum pump, while setting the separator to ''OFF'' in time of nonpressure at the suction side and to ''ON'' or a state of interconnection at atmospheric pressure, respectively. CONSTITUTION:At the point midway in a discharge side circuit A of a vane type vacuum pump 12, an oil separator 35 is installed in a level higher than that of the pump 12. A sliding part spot of the vane outer end edge and a bearing part spot 45 are of the part required for lubrication. A part of lubricating oil is taken away from a discharge part 21 whereby the separator 35 collects the lubricating oil separated by a cyclone into an oil sump part 46. A siphon release valve 48 sets an interval between a suction side circuit B and a return circuit 47 to ''OFF'' when the suction side circuit B comes to the specified suction pressure and makes oil flow back as in an arrow R with a pressure difference between the lubrication required part and the oil sump part 46. When rotation in the pump 12 stops and therefore the suction side circuit B comes close to atmospheric pressure, an interval between the circuit B and the return circuit 47 is set to ''ON'' or a state of interconnection, thus the flow-down of lubricating oil from the return circuit 47 is prevented by the siphon.

Abstract: PURPOSE:To inhibit excess operation, and to improve the sensation of lever operation by supplying a control valve with reverse currents only in a specified short time after a control lever is operated at a neutral position only when the control lever is changed over from the position of drive operation higher than specified operation speed to the neutral position. CONSTITUTION:A controller 12 arithmetically operates the operation speed of a control lever 11 from the change of an output from a potentiometer PM for working a boom cylinder C1 while arithmetically operating the actual operation speed of the boom cylinder C1 from an output from a rotational-quantity detecting sensor S. When the lever is worked in the direction that the boom cylinder C1 is decelerated and the output from the potentiometer PM and the operation speed of the lever are specified values or more, the controller 12 determines the current value of reverse currents from the operation speed of the lever. A reverse current supply means B supplies a control valve V with reverse currents determined until the actual operation speed of the boom cylinder C1 reaches approximately zero after the control lever 11 enters a neutral dead zone.

Abstract: PURPOSE:To prevent any generation of moires or shadows by adjusting the electric potential of a color selecting electrode to be higher than that of a color fluorescent surface, and adjusting the difference between these electric potentials to be sufficient to remove lateral shadows, which divide the beam transmitting holes during the scanning of electron beams. CONSTITUTION:The electric potential of a color selecting electrode 3 is set higher than that of a color fluorescent surface 1. When electron beam scanning is carried out by giving a reduced-speed concave-lens electric field between the electrode 3 and the surface 1, an electron beam scanning area 8, which has slightly larger length and width than the area of a beam transmitting hole 5 of a slot mask, is obtained on the surface 1 as is indicated with a dot line, thereby extinguishing the lateral images of a cross linking part 6. As is indicated in the figure, a high electric potential EHV is given to the surface 1, and a higher electric potential EG, which equals the sum of EHV and EPF is given to the electrode 3. Here, an electric potential difference EPF should be made enough to extinguish exactly the lateral images of the part 6.
