Title: Magnetic bearing device
Inventor: KIYOUTANI HIROTOMO
IPC: F16C32/04
Filed: 1987-01-19
Abstract: PURPOSE:To enable high-speed rotation to be performed by making the width of an inner movable member in a protective bearing smaller than that of an outer fixing member, and increasing the natural vibration number of a rotor shaft. CONSTITUTION:The upper end of a movable member 33 is located at the intermediate part of a ball 34 in an upper row, while the lower end thereof is located at the intermediate part of a ball 34 in a lower row, wherein the movable member 33 is in substantially half the width of a fixing member 32. That is, the inner movable member 33 is small in width so that the groove portion 31 of a rotor shaft 11 is also small in width. Consequently, the rotor shaft 11 becomes shorter in length by the width of the groove so as to enlarge the natural vibration number of the rotor shaft 11. Therefore, the maximum rotational speed of the rotor shaft 11 can be increased, resulting in the high-speed rotation.

Abstract: PURPOSE:To enable reuse of a defective photosensitive body at low cost by etching its surface layer having defects and removing the surface layer, and then, laminating a fresh a-Si layer. CONSTITUTION:A damaged or contaminated a-Si photosensitive body 2 is set in a vacuum vessel 1, the vessel 1 is evacuated with a pump 8, and the body 2 is raised to about 150 deg.C with a heater 7.

IPC: H01F27/24
Filed: 1982-01-27
Abstract: PURPOSE:To prevent the falling off of an iron core plate and facilitate the assembling operation, by forming a spacer from alumina porcelain columns dispersed between iron cores so as to carry a uniformly distributed load, and  heat- resistant insulating films bonded to the upper and lower end surfaces of  the columns, respectively. CONSTITUTION:Between polyester unwoven fabrics 1 and 2 having a diameter substantially equal to that of a disc-shaped iron core, not shown, a polyester film piece 2 having a diameter equal to that of the fabrics 1 and 3 is inserted and fused thereto to form a heat-resistant insulating film, which is pressure- bonded to each of the upper and lower end surfaces, coated with an epoxy resin bonding agent, of a plurality of alumina porcelain columns 4. These columns 4 are disposed between the upper and lower iron cores so as to carry a uniformly distributed load. Thus, it is possible to prevent the short-circuit accident of the shunt reactor due to the falling off of an iron core plate which may occur in the case of the conventional spacer. Moreover, the operation for inserting the the spacer is facilitated, since the alumina porcelain columns 4 and the heat- resistant insulating films 2 are formed into a unitary body.

Abstract: PURPOSE:To obtain a complete picture signal output even by using a light source of low illumination for illuminating an original or high speed reading scanning and to improve a sensitivity by selectively resetting a picture information output to the shift timing of a shift register. CONSTITUTION:Every time when the pulse of a shift signal (a) comes from a shift signal generating circuit 11, the shift register of an image sensor 10 is operated and a counter 14 changes the inverse of Q output (e) to L by one cycle of the shift signal for every input of the three pulses of the shift signal (a).
