IPC: B41N3/04
Filed: 1987-08-05
Abstract: PURPOSE:To enhance printing capacity or printing durability and to enhance the controllability and stability of a process or the controllability of grain, by repeatedly performing the electrolytic surface roughening treatment of an aluminum support in an acidic electrolyte while interposing smut removing treatment on the way before performing the post-treatment thereof in the acidic electrolyte. CONSTITUTION:An AC current having a commercial three-phase AC as a power source waveform is applied between an aluminum plate and the electrode opposed thereto in an electrolyte containing nitric acid to apply electrolytic surface roughening treatment to the aluminum plate and the treated aluminum plate is immersed in an aqueous solution containing nitric acid to remove smut and the aC current having the commercial three-phase AC as the power source waveform is again applied between the aluminum plate and the electrode opposed thereto in the electrolyte containing nitric acid to apply electrolytic surface roughening treatment to said aluminum plate. Next, a DC current obtained by rectifying the commercial three-phase AC by thyristor is allowed to flow between the aluminum plate and the electrode opposed thereto in an electrolyte containing sulfuric acid to perform post-treatment performing the removal of the smut formed by electrolytic surface roughening treatment and the minute dissolution of aluminum.

Title: Position controller
Inventor: OOTSUKA TSUTOMU
IPC: G05B11/36
Filed: 1982-11-08
Abstract: PURPOSE:To obtain a position controller having its stable holding position by providing a switch means to increase automatically the loop gain of a position control system and having the satisfactory resistance to a disturbance that produces the position variance. CONSTITUTION:A position is controlled, and the position detecting signal PFB of a present position register 11 is coincident with the position command signal POS of a position command register 10. Under such conditions, the digital value is set at zero for the differential signal ERR of a subtractor 12. Therefore a speed reference signal SRS of a D/A converter 13 is also set at zero to complete the positioning control. At the same time, the output signal of an OR circuit 14 is set at a low level with the output signal of an NAND circuit 15 set at a high level respectively. Thus an FF16 is set, and a switch 17 is closed by the output signal 16A. This increases the loop gain of a position control system. The FF16 is set and held by the circuit 15 until the signal POS is set and the reset signal RST is applied. As a result, a large loop gain is held only in a pause mode of the positioning control.

Title: Dynamic pressure gas journal bearing
Inventor: MAKINO TAKERO
IPC: F16C17/03
Filed: 1994-07-27
Abstract: PURPOSE:To increase a load by a method wherein a groove is formed in the front edge in a rotation direction of the recessed curved surface of a pad and parts having no groove are formed at two end parts in an axial direction, the central part in an axial direction of the groove reaching the rear edge side in a peripheral direction from a pivot support point is shallow, and the curvatures of the two end parts are set to a value between the curvatures of the groove part and the rotary shaft. CONSTITUTION:Lands 6 remain at two end parts in an axial direction on the surface of a pad 2 and a shallow groove part 7 is formed. Rails 9 slightly deeper than a central part 8 are formed at the two ends of the groove part 7. The rail 9 is formed in such a manner that depth is gradually decreased toward the rear edge of the pad 2 and depth at the rear edge is set to a value equivalent to that of the central part 8 of the groove. When the radius of a rotary shaft is R, the curvature of the groove central part 8 is set approximate 1,001-1,003 R and the curvature of the land 6 is set to a value lower than that of the groove central part. When projection is effected from an axial direction, the groove central part 8 is prevented from protruding from the land part 6. This constitution prevents the generation of the stress of a bearing surface, making centralized contact, in the position of the pivot point, and improves load bearing ability of a bearing without damaging gas pressure generating performance of a gas bearing.

Filed: 1987-08-04
Abstract: PURPOSE:To reduce the dimension of the motor driven power steering device by installing each revolution angle sensor onto the upper side and lower side column shafts and detecting the torsion of the column shaft by these revolution angle sensors. CONSTITUTION:A direct drive motor DM consists of a motor 7 and a stator 8, and said stator 8 is fixed onto a motor case 9. A slit plate 12A is fixed onto the lower edge part of an upper side column shaft 2A, and a revolution angle sensor 12 having the light transmitting and receiving bodies, having the slit plate nipped, is arranged on the outer periphery of the slit plate. A revolution angle sensor 13 having the same constitution is arranged also on a lower side column shaft 2B. Since the torque generated on the upper side column shaft 2A can be obtained from the output voltage difference of the both revolution angle sensors 12 and 13 arranged in the motor case, the need of installing a torque sensor at the position different from that of the motor DM in the conventional is avoided, and the small-sized device can be obtained.
