Title: High speed rotary shaft bearing
Inventor: ABE ISAO
IPC: F16C15/00
Filed: 1985-04-12
Abstract: PURPOSE:To enable high speed rotation by giving initial loads to dampers supporting a housing in which a ball or roller bearing is housed for supporting a high speed rotary shaft. CONSTITUTION:A high speed rotary shaft 1 is supported with a bearing housing 2 and a supporting block 3. A ball or roller bearing is housed in the bearing housing 2.

Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To solve the instability by individual difference of an air supplying system just after starting, and quickly perform the blowing-up of an engine by feedback controlling the engine rotating speed just after the start of the engine, and limiting the feedback control after air increase correction is started. SOLUTION: When an ignition switch is on, whether the engine rotating speed exceeds, for example, 500rmp or not is checked in an ISC control device 8, and when it is 500rpm or less just after starting, an opening control signal is calculated on the basis of a correction variable for ISC feedback control and a correction variable for air increase correction to control an ISC valve 7. Thereafter, when the engine rotating speed rises and exceeds 500rpm, ISC feedback control is stopped, and air increase correction is started. When the engine rotating speed once exceeds 500rmp and reaches self-excited rotating state, the air increase correction is performed as the feedback control is stopped to ensure the blowing-up.

Abstract: PURPOSE:To increase the response power to a load and to enhance the cooling effect, by forming a plane having an approximately true circle shape, which faces a rotor core of a pole part, providing magnetic resistance holes on both sides of the pole center part, and bringing the magnetic flux distribution of the magnetic poles closer to a sine wave. CONSTITUTION:The magnetic pole parts 3 are extended to the right and left of a yoke part 2 to which a coil is provided. The tips of both magnetic poles 3 are linked by a bridge part 4. Furthermore, the part 6 of the inner diameter of a stator core facing the rotor core 9 with a gap 11 being provided is formed in a shape of an approximately true circle, except for the bridging part 4 and a shading coil winding part 8. At a suitable part on the both sides of the center of magnetic pole, are provided one or plurality of the magnetic resistance holes 12. In this constitution, since the magnetic flux distribution in the gap 11 is brought closer to the sine wave, the trough in a torque curve becomes small. Since the magnetic resistance holes 12 also serve as ventilating holes, the cooling effect is enhanced.
