Title: Spindle motor
Inventor: OKU YOSHITO
IPC: H02K5/167
Filed: 1992-07-15
Abstract: PURPOSE:To suppress not only the diametrical displacement of a rotor but also the axial displacement enough small, and bear a rotary sleeve part rotatably with a bearing body without necessity of replenishment of an lubricant, and effectively prevent the scattering of the lubricant to outside. CONSTITUTION:A rotary sleeve part 10 comprises an inner tube 12 made of nonferromagnetic material, a middle tube 14, and an outer tube 16 made of a ferromagnetic material. A rotary sleeve 10 is set on the bearing body 34 made of ferromagnetic material, rotatably gaps 85 apart in axial direction and radial direction. A magnetic circuit, where the magnetic flux by a circular permanent magnet 24 passes, passes the bearing body 34 via an upper seal gap part 82 and a collar part 26d from the outer tube 16, and returns to the outer tube 16 via a collar part 32 and a lower seal gap 84. Both ends of the magnetic fluid lubricant 86, which has reached every part of the gap 85, are retained magnetically by seal gaps 82 and 84.

Title: Deceleration sensing type load corresponding hydraulic control valve
Inventor: KOUNO TERUHISA
IPC: B60T8/28
Filed: 1983-11-09
Abstract: PURPOSE:To prevent the shortage of the sealed-in pressure on sharp brake application by forming an orifice into a liquid sealing circuit on the downstream of an inertial valve and installing a differential-pessure valve which opens the bypass passage of the orifice when the difference of the liquid pressure before and behind the orifice reaches a prescribed value. CONSTITUTION:A movable valve body 22 equipped with a sealing valve 20 and a bypass passage 21 and a differential-pressure valve 25 constituted of a fixed valve seat 23 for the contact with the sealing valve 20 and a compression spring 24 for urging the movable valve body 22 in the valve closing direction are installed into a passage 18 close to an inertial valve 16. When the input hydraulic pressure reaches a prescribed value, the valve body 22 shifts leftward, compressing the spring 24. Therefore the sealing valve 20 is departed from the valve seat 23, and the bypass passage 21 is opened. Therefore, the input hydraulic pressure flows into the passage 18, without being applied with throttle effect. The operation starting time of the differential-pressure valve 25 is delayed as the pressure increasing speed increases, because of the spring 24. Therefore, the shortage of the sealed-in hydraulic pressure on sharp brake application is prevented, and the sealing-in of an excessive pressure is prevented.

Abstract: PURPOSE:To carrying out tilling operation of desired tilling depth corresponding to crops by changing length of a pawl washer to be equipped with a tilling pawl from the shaft periphery of a tilling shaft and varying tilling depth in the same tilling rotor by using the same tilling pawl. CONSTITUTION:In a tilling rotor 6, tilling pawls 7 are attached to a pawl washer 28 supported on a rib 27 on the shaft periphery of a tilling shaft 26 held in a transmission case 5 and the tilling pawls 7 are fixed to the outer periphery of an extended tilling shaft 30 connected through a flange 29 to the outer edge of the tilling shaft 26. Then, at a central part near the transmission case 5, revolution radius of the tilling pawls 7 to be equipped through the pawl washer 28 is enlarged and deep tilling is carried out. On the contrary, the tilling pawls 7 at part of the extended tilling shaft 30 have smaller revolution radius and shallower tilling than the central part is performed. The deep tilling part corresponds to a mulching row forming part formed by a mulching apron 25. Since the pawl washer 28 is supported through the rib 27 on the tilling rotor 6, the tilling pawls 7 having the same length and the same strength can be used as they are.
