Filed: 1984-03-02
Abstract: PURPOSE:To descale surely during sizing by specifying a stage for starting descaling at the time of sizing a seamless steel pipe by a sizing mill consisting of plural stands in the seamless steel-pipe manufacture of Mannesmann plug-system. CONSTITUTION:In a method for sizing a seamless steel pipe by a sizing mill consisting of plural stands; after rolling the pipe by the 1st stand of the mill, highly pressurized water is sprayed on the outer surface of a pipe stock at the front of at least the 2nd stand, to descale said outer surface. For instance, the 1st and 2nd highly-pressurized water spraying headers 5, 6 are arranged on the backsides of the stands 1, 2 of the stands 1-4 of sizing mill. The water is sprayed on the surface of pipe stock from the header 5 by a load cell when the pipe stock is bitten by the stand 1 to descale the pipe surface, and the header 6 performs the descaling in the same manner when the pipe stock is bitten by the stand 2. By this method, the scales are easily stripped under light rolling reduction, and the descaling is surely performed by water of comparatively low pressure.

Filed: 1988-02-23
Abstract: PURPOSE:To provide auxiliary cell function in a small cell space, by using auxiliary cells whose number is smaller than that of a main cell and providing a boosting circuit for compensating the undervoltage of the auxiliary cells. CONSTITUTION:When a switch 4 is turned ON to drive a motor 5 by main cells 7 and the capacity of the main cells 7 is subsequently extincted, a switch 6 is turned to the side of auxiliary cells 8 and the motor 5 is driven through the auxiliary cells 8. Since the number of the auxiliary cells 8 is smaller than that of the main cells 7, the output voltage of the auxiliary cells 8 is lower than that of the main cells 7. In order to match the voltage levels, the output voltage of the auxiliary cells 8 is boosted through a boosting circuit 9 to the output voltage level of the main cells 7 and the boosted voltage is applied to the motor 5.

Title: Brush
Inventor: IGAMI TADAHITO
IPC: H02K13/00
Filed: 1985-03-01
Abstract: PURPOSE:To prevent a spark from generating by reducing the brush resistance value of the contacting surface of a brush with a commutator in the rotating direction of the commutator so that the value at the center becomes small, thereby enhancing the resistance value when the brush starts or end contacting the commutator segment.

The ratio of the resistance values is preferably selected to approx. 1/1.1-1/100. Thus, since the resistance of the portion which starts contacting with or separating from the segment increase, a speak generation is suppressed, a brush life is increased, and a noise can be reduce.

IPC: F04C18/00
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To freely generate a strong window by traveling a wind generating vehicle within a tube, putting a partitioning the tube when a sufficient force is provided, and pushing the air by the inertial force of the wind generating vehicle. SOLUTION: When a wind-generating vehicle is traveled within a doughnut- like tube and a partitioning plate 3 corresponding a valve is operated, a wind of optional speed can be generated according to the ratio of both tube sectional areas. When the partitioning plate 3 is operated to send a wind after the wind- generating vehicle is run round many times up to a sufficient speed, the inertial force by the dead weight of the vehicle can be used to push the air, and a stronger airflow can be freely formed. When this method is applied to a station in railroad for passenger, a strong acceleration can be obtained. In case of cargo transportation, it is perfect for a strong acceleration in cargo transport, and the necessity of forming and storing compressed air can be eliminated.
