Title: Controlling method for rotating speed
Inventor: SEI MAKIO
IPC: H02P3/06
Filed: 1982-10-07
Abstract: PURPOSE:To obtain a rotating speed controlling method for sufficiently reducing the irregular rotation by operating the added result of 2-phase outputs of rotating speed detector as speed control signals, and stopping at the prescribed position with the 2-phase outputs separately used at the decelerating and stopping time. CONSTITUTION:When switches S1, S2 are turned ON by a command controller 140, switches S3, S4 are turned OFF and a start signal is generated at the time t1, a voltage is applied to a capstan motor 110 to accelerate the motor. The output frequency of a rotating speed detector D is counted by a counter in the controller 140 at t1-t2, and when it becomes the set counted value, a constant- speed operation is started, the switches S1, S2 are turned OFF, the switches S3, S4 are turned ON, the detection signals of phases A, B are added by a calculator amplifier 30, the periods are averaged to obtain a low irregular rotation characteristic. When the position signal of a video tape 100 is detected by a head 130 at the time t3, a tracking signal is generated by a control signal, the switches S1, S2 are turned ON, the switches S3, S4 are turned OFF, and stopped at the prescribed position.

Title: Alignment mechanism for upper surface plate of lapping device
Inventor: ARAI HATSUYUKI
IPC: B24B37/08
Filed: 1999-06-22
Abstract: PROBLEM TO BE SOLVED: To eliminate the eccentricity of an upper surface plate, and to smoothly lower the upper surface plate during the lapping. SOLUTION: A round projection 8 is provided on an inner circumferential surface of a hole 7 in an upper surface plate 6, and its tip is brought into contact with an outer circumferential surface of a driver when the upper surface plate 6 is lowered. When the tip of the projection 8 on the inner circumferential surface of the hole 7 of the upper surface plate 6 is brought into contact with the outer circumferential surface of the driver 3, a play in the horizontal direction between the upper surface plate 6 and the driver 3 is eliminated, and the upper surface plate 6 is connected to the driver 3 with their axes aligned with each other.  When the lapping is advanced, and the thickness of a work 18 is changed, the projection 8 of the upper surface plate 6 is brought into point- contact or line-contact with the outer circumferential surface of the driver 3, and thus, a part of the inner circumferential surface of the hole 7 of the upper surface plate 6 is not hooked by the driver 3 side, and the upper surface plate 6 is smoothly lowered following the change in thickness of the work 18 to continuously apply the specified pressure to the work 18.

Title: Different speed rolling mill
Inventor: TONOBE TAKEHIKO
IPC: B21B37/46
Filed: 1985-08-09
Abstract: PURPOSE:To eliminate the need for a spindle and reduction gear and to simplify the entire part of a driving system for work rolls in the stage of rolling a rolling material with two pieces of work rolls having different circumferential speed by connecting a liquid pressure motor to each work roll shaft. CONSTITUTION:Pressure oil is circulated in circulation pipeline 5, 6 by hydraulic pumps 9, 10 driven by motors 7, 8 and hydraulic motors 3, 4 are run by the pressure oil to drive the work rolls 1, 2 having the different circumferential speeds in the stage of winding the rolling material on the work rolls 1, 2 and rolling said material. The former of the rolls 1, 2 is driven at a low speed and the latter at a high speed. The speeds are controlled by detecting the rotating speeds of the motors 3, 4 with speedmeters 11, 12 and changing the angle of inclination of the swash plates or bent axes of the pumps 9, 10 to control the discharge oil flow from the pumps 9, 10. The driving system for the work rolls is thus made simple without requiring the spindle and reduction gear.

Title: Method of correcting amount of injection of each cylinder in electronic control diesel engine
Inventor: TSUKAMOTO KEISUKE
IPC: F02D41/40
Filed: 1984-08-23
Abstract: PURPOSE:To properly correct an amount of injection at all times by adding to an accumulated value of amounts of correction, one yielded by multiplying the amount of correction for every time estimated in response to deviations among variations of rotation for each cylinder by a coefficient of correction estimated in response to amounts of the variations of the rotation. CONSTITUTION:An ECU58 judges, in operation of an engine, whether or not a state of NE1 is two cylinders or more of being a minimum value Nl among NE1-NE4 for the same number of a cylinder in the rmp NEi (i=1-4) of an engine for each 45 deg. CA under the condition of the engine being under an idle stable state. Judged YES, the NE1 is determined to be the minimum rpm Nl, and furthermore the miximum rpm is retrieved among the rpms other than the NE1 and is designated as Nh. In succession, variations of rotation for each explosion cylinder are detected from a difference between the rpms Nh and Nl, and an amount of correction is estimated in conformity with a deviation between an averaged value of said detected variations of rotation and variations of rotation for each cylinder. An amount of injection of the engine is corrected on the basis upon a value yielded by multiplying said amount of correction by a coefficient of correction estimated in response to the amount of variations for each rotation.
