Abstract: PURPOSE:To omit machining of a permanent magnet and bonding step and to make it possible to form a highly reliable magnetic component at a low cost by providing a unitary body of the permanent magnet and a yoke by using press molding. CONSTITUTION:A part to be filled A in a press is filled with a mixed material comprising permanent magnet powder and a thermosetting resin. An oriented magnetic field H is applied. Under this state, pressure P is applied to a lower punch B, and press molding is performed in the magnetic field. After demagnetization, a filling part I is filled with the powder of high permeability material and a thermosetting resin. Thereafter, the pressure P is applied to a lower punch C, and a part corresponding to a yoke is molded as a unitary body. Heating and hardening are performed in a constant temperature oven. At this time, a bonding agent in a magnet molding body and a bonding agent in the high permeability material are bonded, and magnetic components N and M which form a unitary body are obtained. In this way, a bonding step is not required, and the cost is decreased. The machining of the magnet is not required. The filling rate of the high permeability material at the yoke part is increased. Therefore, the high performance can be implemented for the magnetic component.

IPC: F16H25/24
Filed: 1990-05-24
Abstract: PURPOSE:To prevent durability of a ball screw from deteriorating even in highness of a speed by providing a vibration absorbing means in a slider part to bring one end part into contact with a ball nut part and absorbing vibration in a direction at a right angle with an axial direction of the ball nut part. CONSTITUTION:A slider main unit 13 is supported rigidly in right/left horizontal directions in a direction in parallel to an axial direction of this main unit and softly in a vertical direction in a direction orthogonal to the axial direction, relating to a ball screw 6. In a parallel spring part 12, vibration in a vertical direction of a ball nut part 9 and a ball nut connecting part 11, that is, vibration in a vertical direction of the ball screw 6 is positively amplified and transmitted to the slider main unit 13. However, a rod of dampers 18, 18, provided in the main unit 13, is brought into contact with the ball nut connecting part 11, so that vibration energy of these parts is all absorbed by each damper 18, 18 even when the slider main unit 11 is vibrated in a vertical direction. Accordingly, a permissible rotational speed can be increased by exceeding a hazardous speed not resonating with a proper resonance frequency provided in a screw shaft of the ball screw 6.

Title: Hydraulic pump device
Inventor: SHIRAGA JUN
IPC: F04D5/00
Filed: 1988-06-01
Abstract: PURPOSE:To prevent the uncomfortable noise due to the discharge of fluid by closing the end surface in the flowout direction in the case of the flowout of the fluid to an exhaust through hole with a rubber mount and providing a damper member for dumping the flow inside thereof. CONSTITUTION:When, air is exhausted outside a pump chamber, a small fuel discharging together with the air is discharged from an exhaust through hole 31F and thereafter flows in a damper chamber 31G formed in a pump cover 31 so as to collide to a rubber mount forming the one end surface of the damper chamber 31G and is discharged from the end to the outside of the pump chamber with the flow rate changed by means of the damper member. Further, the pulsation generated by rotating an impeller produces turbulent through the collision to the rubber mount or the damper member, thereby reducing the pulse height value and frequency and thereafter is discharged from the end of the pump cover 31. This eliminates the resonance in a tank so that it is possible to prevent the uncomfortable noise.
