Title: Linear motion table with built-in motor
Inventor: OMORI SHIGENORI
IPC: H02K5/26
Filed: 1991-04-25
Abstract: PURPOSE:To facilitate miniaturization, high speed control, reduction of the number of parts, small noise and an assembly process of a linear motion table. CONSTITUTION:A stator 40 is fitted to a table 30, and a rotor 20 is coaxially arranged in the stator 40 by two bearings 44. When the rotor 20, connected to be screwed to a ball screw 10, is rotated, the rotor 20 is moved to right/left on the ball screw 10 to move the table 30. Since the table 30 is directly controlled not through the ball screw 10, position control at a high speed can be performed.

Title: Image reader and its control method
Inventor: CHAGI ATSUSHI
IPC: G03B27/50
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To obtain a reader capable of appropriately reducing unevenness in the temperature distribution of an original platen according to circumstances without needlessly lowering productivity and without providing a complicated cooling mechanism by deciding a backward moving speed, based on a copying speed and a moving distance obtained on the basis of the size of an original. SOLUTION: The copying speed is decided, based on the temperature of a platen glass 16, and further the moving distance is obtained, based on the size and the placing direction of the original 8, then the backward moving speed is decided, based on the copying speed and the moving distance. Thus, generated heat by a lamp unit 6 is widely dispersed on the platen glass 16 without making the unit 6 stay at a read starting position S for a long time. Furthermore, the backward moving speed is set to an optimum value fit to the size and the placing direction of the original, so that the unevenness in the temperature distribution on the glass 16 is appropriately reduced without needlessly lowering the productivity.

Title: Automatic control circuit for da converter
Inventor: NISHIMUTA NAOMITSU
IPC: H03M1/10
Filed: 1988-05-19
Abstract: PURPOSE:To prevent a meaningless large output voltage from being sent by adding an inverting voltage, for which the output voltage is inverted, to this output voltage when the gain of a DA converter is controlled and cancelling the output voltage. CONSTITUTION:An inverting amplifier 3 is provided to generate the inverting voltage, for which the polarity of the output voltage of a DA converter 1 is inverted. When the gain is controlled, this inverting voltage is added and an almost zero voltage is sent. Next, whole off-set adjustment to include the DA converter 1 and a buffer amplifier 2 is executed. Thus, when the gain is controlled and off-set of the DA converter 1 is adjusted, the meaningless over voltage is prevented from being sent to an external part.

Title: Polarization diversity optical receiver
Inventor: SHIBUYA MAKOTO
IPC: H04B10/61
Filed: 1988-05-20
Abstract: PURPOSE:To suppress deterioration in sensitivity due to the limitation of a dynamic range by holding the intensity of an IF signal inputted to a demodulating circuit at the best value for the demodulation circuit by an automatic gain control circuit at all times, and adjusting the intensity of a base band signal by a variable gain adjuster and then mixing it.

Title: Radial ball bearing for protection in magnetic bearing device
Inventor: KAWAKAMI YOSHIHISA
IPC: F16C39/02
Filed: 1987-05-20
Abstract: PURPOSE:To increase the allowable slanting angle of a bearing so as to prevent generation of any excessive inner stress and improve durability of the bearing in the case of touch down by increasing a ratio of the curvature radius of the raceway groove of an inner ring against the diameter of a ball in a radial ball bearing for protection. CONSTITUTION:In the case of touch down, when a rotor makes contact with the outer ring 13 of a bearing 10, some slant is generated on the bearing 10. But, by enlarging the curvature radius ri of a groove, an allowable slanting angle becomes larger and an excessive stress does not appear inside of the bearing 10. In the case of the same slanting angle, a revolution speed of the ball 11 becomes smaller as the radius ri becomes larger and the rotation becomes smoother, and in the case of startup of high speed rotation, by enlarging the radius ri, contact surface pressure between the ball 11 and the raceway groove 14 becomes larger and a normal rotation of the ball 11 can be performed easily from the beginning. When the radius ri is set to an extent of 0.53-0.58Da (Da is the diameter of the ball 11), the bearing can be improved in durability and hardly damaged.
