Title: Structure for supporting motor of spinning frame
Inventor: TSUJINO KATSUSATO
IPC: D01H1/241
Filed: 1994-04-12
Abstract: PURPOSE:To support a motor in a state to be movable in the direction to vary the distance between the rotary shaft of the motor and a driving shaft without necessitating too much space for the size of the motor in the width of the machine frame. CONSTITUTION:A supporting base 10 is horizontally placed on the out end OE of a machine frame 1 and a base plate 11 is placed on the supporting base 10 in a state rotatable around a shaft 11a placed parallel to a driving shaft 2 and inserting two bolt shafts 15 vertically protruded from the upper surface of the supporting base 10 into an oblong hole 16. A main motor 6 is fixed nearly at the center of the upper surface of the base plate 11 in a state to direct the rotational shaft 6a parallel to the driving shaft 2. The tension of a belt 9 extended between a motor pulley 8 and a drive pulley 5 is adjusted by varying the inclination angle 6 of the base plate 11 relative to the supporting base 10. The base plate 11 is fixed to the bolt shaft 15 through a spherical washer 17 with a nut 18 keeping a prescribed inclination angle relative to the supporting base 10.

Title: Vent system for steam condenser
Inventor: ISHIYAMA TAKENORI
IPC: G21C15/18
Filed: 1989-03-28
Abstract: PURPOSE:To stabilize the condensation of steam by providing a steam condenser submerged in a cooling pool and providing a condensate line of the steam condenser with a jet scrubber. CONSTITUTION:In a vent system, a main steam pipe 5 is quickly cut off at the time of an accident of loss of a cooling material. Steam in a reactor pressure vessel 2 is led to a steam condenser 8 through a steam supply line 7 and is condensed and is returned to the nuclear reactor pressure vessel 2. When an emergency reactor core cooling system is operated, the reactor pressure is temporarily made negative, and the condensing function is reduced when nitrogen is mixed into the condenser 8. In this case, a second remote control valve 11 is closed and a third remote control valve 13 and a fourth remote control valve 14 are opened to supply condensate to a jet scrubber 16, and nitrogen flowed from a nitrogen vent line 15 is discharged to a header tank, and water is stored in the header tank 17, and nitrogen is discharged to the periphery. Thus, steam is stably condensed.

Title: Take-up roller
Inventor: ENDOU TETSUHIKO
IPC: B65H54/86
Filed: 1981-05-15
Abstract: PURPOSE:To prevent the breaking of a thread upon the changing of the thread in a rotary shaft type waste roller provided for temporally taking-up the thread upon doffing, by automatically decreasing the speed of the waste roller in association with increase in the take-up diameter of the thread on the waste roller. CONSTITUTION:A roller 8 is mounted onto a shaft 7 through, for example, plain bearings 802, 803 in order to give a slip between the shaft 7 and the roller 8 under thread tension for waste take-up. Therefore, when the winding tension is increased in association with increase in the take-up diameter of the thread on the roller 8, the speed of the roller 8 is automatically decreased due to the slip between the roller 8 and the drive shaft 7, since the take-up tension acts as braking force to the rotation of the roller 8. With this arrangement, it is sufficient to remove the thread on the roller 8 at the rate of one time to at least four to five times of doffing operations, thereby the amount of work may be reduced to one-fourth of that of the conventional work and the breaking of thread due to the increase of thread tension is prevented from being occurred.

Title: Speed change control device for automatic transmission gear
Inventor: ISHII KOZO
IPC: F16H59/74
Filed: 1989-03-27
Abstract: PURPOSE:To maintain the acting performance of a drift-on ball so as to prevent the delay of speed change by setting the fastening pressure of a hydraulic clutch provided with the drift-on ball high for the specified period only at the time of speed change accompanied by the lowering of load. CONSTITUTION:In the speed change control device for an automatic transmission gear AT, when a judging means D judges the speed change stage of fastening a hydraulic clutch E with a drift-on ball C, hydraulic pressure is fed into the hydraulic clutch B by a speed change control means E so as to perform the fastening operation. In this case, when a speed change state detecting means F detects that the shifting into the speed change state is generated accompanied by the lowering of load, the fastening pressure to be fed into the hydraulic clutch B is set high for the specified period by a hydraulic pressure control means G, and the closing action of the drift-on ball C is performed rapidly so as to maintain its acting performance. The drag of the clutch can be thus prevented as well as the fastening pressure is heightened only at the time of minimum required speed change so as to make it possible to reduce the speed change shock at the time of other speed change.
