Title: Method for cold-rolling ba-finished stainless steel strip
Inventor: OKIYAMA TAKUJI
IPC: B21B37/48
Filed: 1994-08-17
Abstract: PURPOSE: To provide a cold rolling method of a BA-finished stainless steel strip by which the consumption of a guard sheet is remarkably reduced. CONSTITUTION: After the stainless steel strip coil 23 is mounted on the front reel 13 of a 20-stage Sensdzimir mill 11, the coil is uncoiled, bitten between a pair of upper and lower small diameter work rolls 17 together with a rolling agent, cold-rolled and coiled with a rear reel 14. After completing the cold rolling of a 1st pass, draft adjustment is executed and the cold rolling of the 2nd pass is executed in the reverse direction to the 1st pass. This reverse cold rolling is repeatedly executed. Tension is set so that the absolute value of the difference between the uncoiling tension at the n-th pass of the stainless steel strip 25 and the coiling tension at the (n-1)th pass is <=2.0kgf/mm<2> at the midway passes in reverse cold rolling and cold rolling is executed without using the guard sheet. On the other hand, the stainless steel strip 25 is coiled while inserting the guard sheet 24 between the layers of the coil.

IPC: F28F13/18
Filed: 1988-08-04
Abstract: PURPOSE:To maintain a large heat transfer area for improving the heat transfer capacity by forming pipe-peripheral direction grooves closer to central side of the surface of a pipe than pipe-axial direction grooves, and connecting the pipe-peripheral direction grooves each other through tunnel-like holes that are formed at intersecting points of the pipe-axial and pipe-peripheral direction grooves. CONSTITUTION:A large number of pipe-axial direction and pipe-peripheral direction grooves 11 and 12 are provided on the exterior surface of a heat transfer pipe 10. The pipe-peripheral direction grooves 12 are formed closer to central side of the pipe, i.e., in a deeper position, than the pipe-axial direction grooves 11. Each of fins 13 is reduced in its width and thickness towards its top so as to form a protruding pin of a pyramid shape, and they are arranged in the pipe-axial direction in rows across the pipe-peripheral direction grooves. The exterior heat transfer surface area of the heat transfer pipe 10 is increased by a large number of the fins 13, causing an increase in the evaporation capacity. Penetration holes 20 of a tunnel- like shape are provided under the pipe-axial direction grooves 11 at positions where the pipe-axial and peripheral direction grooves 11 and 12 intersect each other, and the pipe- peripheral direction grooves 12 are connected each other through the penetration holes 13. As the flow of refrigerant in the pipe-peripheral direction is restrained by the penetration holes 20 provided on the pipe-peripheral direction grooves 12, the spread of refrigerant in the pipe-axial direction is promoted.

IPC: H02P23/00
Filed: 1983-10-19
Abstract: PURPOSE:To increase the stability of a synchronous motor by locking the output of an overcurrent limiter at the system fluctuation time or switching a changeover switch from an automatic voltage regulator to a constant excitation controller. CONSTITUTION:When a shortcircuit defect occurs at a bus 1, the voltage of the bus 1 decreases, and a synchronous motor 5 supplies a delay reactive current to the shortcircuit point. Since the delay reactive current is leading reactive current as seen from an overcurrent limiter 8, the limiter 8 outputs a limit output to an automatic voltage regulator 7 to weaken the excitation, However, an overcurrent relay 13 detects the current from the motor to open the b-contact 13b, thereby interrupting the output of the limiter 8. Accordingly, the regulator 7 controls to strengthen the excitation in response to the degree of decreasing the electric chain of the bus 1 to control to strengthen the excitation, thereby increasing the stability of the motor 5.

Title: Lock-up control device for automatic transmission
Inventor: TANEOKA HIDEYUKI
IPC: F16H61/14
Filed: 1999-07-08
Abstract: PROBLEM TO BE SOLVED: To minimize the operating frequency of lock-up release for avoiding a deceleration shock to improve the durability of a lock-up clutch. SOLUTION: Engine torque Te is estimated based on the relationship between the amount of intake air and the engine speed (S2), impeller driving torque Tp is determined from the relation between the engine speed and the differential pressure between apply pressure for operating a lock-up clutch and release pressure, the impeller driving torque Tp and the engine torque Te are compared with each other (S3), lock-up is released when the engine torque becomes below the impeller driving torque Tp (S4). When the engine torque Te becomes below the impeller driving torque Tp, reverse driving force is transmitted from the car body side to the engine side, and thus deceleration shock to a driver can be avoided by releasing lock-up. Since the lock-up is released only at the time when decelelation shock is generated, the frequency of lock-up releasing is minimized.
