Filed: 1990-07-12
Abstract: PURPOSE:To treat slime easily and efficiently in a short time by inhibiting the agitation of a liquid at a desired position in the liquid in an excavated pit and effectively filtering and removing soil and sand in the liquid. CONSTITUTION:An underwater pump 10 is hung down at the desired position of an excavated pit 2 filled with in-pit water 5 containing slime such as soil and sand, the pump 10 is driven, and the in-pit water 5 is sucked and drained from a drain pipe 12. Flowing-out waste water is made to collide with a baffle plate 14 and blocked, and dispersed in a bag body 16, and slime is filtered, and clean waste water is flowed out to the outside. Consequently, storage into the bag body 16 of slime is continued, the bag body 16 is hung up by a main cable 11 after slime reaches a fixed quantity, and slime on the inside is thrown away. The underwater pump 10 is again moved to another position in the pit 2, the same operation is repeated, and slime in the excavated pit 2 is removed.

Title: Yarn switching method
Inventor: IWAKI SEIJI
IPC: B65H67/048
Filed: 1990-07-13
Abstract: PURPOSE:To prevent generation of fluff by permitting a yarn to refrain from touching an empty bobbin until movement is made to the yarn switching position, and detaining the yarn with the yarn catching groove provided in the empty bobbin when it moves to the yarn switching position. CONSTITUTION:When a yarn is to be switched from a full wound bobbin 40A to an empty bobbin, a yarn path restricting guide 8 is moved to between these bobbins 40A, 40B before the running yarn taken up on the full wound bobbin 40A comes into touch with the empty bobbin 40B to permit the yarn to refrain from touching the empty bobbin 40B until it moved so the yarn switching position. When the empty bobbin 40B comes to this position and the yarn touches the empty bobbin 40B, the yarn is detained with a yarn catching groove provided in empty bobbin 40B through the action of a yarn hooking guide 10 which has been moved to between the yarn path restricting guide 8 and the empty bobbin 40B. This minimizes the yarn touching angle to the empty bobbin 40B, which prevents generation of fluff.

IPC: F16K3/02
Filed: 1981-11-21
Abstract: PURPOSE:To prevent the damage of a screw shaft and a girder by a method wherein the stress caused by the deflection of the screw shaft and the thermal deformation of the device is absorbed by a nut by shaping the upper and lower surfaces of the nut arranged in the girder into substantially spherical surfaces. CONSTITUTION:The torque of a motor 19 is transmitted to a driving shaft 17 through a clutch 20 to elevate a damper blade 3. The torque of the driving shaft 17 is transmitted further to respective screw shafts 8a, 8b at gear boxes 11a, 11b to elevate the girder 6 through the nuts 12 engaging with the screw shafts 8a, 8b by the screw threads thereof. The upper and lower surfaces of the nuts 12 are shaped into substantially spherical surfaces, therefore, the nuts 12 are swung in the girder 6 with respect to the displacements thereof even though the screw shafts and the girder are deformed due to the deflections of the screw shafts 8a, 8b or the thermal deformation of the main frame of the device, and thereby preventing the stress concentrations in the parts which are engaging by the screws. According to this method, damages will never be caused in both of the screw shafts and the girder.

Title: Drawing method
Inventor: SAKAMOTO TATSUJI
IPC: B21D24/04
Filed: 1988-07-26
Abstract: PURPOSE:To prevent a forming defect such as a fold, etc., by executing the forming by small blank holder pressing force from the time point when a punch comes into contact with a blank to the vicinity of the time point when a shape failure is generated in a formed part, and thereafter, increasing suddenly the blank holder pressing force within a range in which it is not ruptured. CONSTITUTION:A formed part is formed from a blank 1 of a steel sheet by a forming method by a double action press, etc. When blank holder pressing force is set to a constant prescribed value by about middle pressure and forming is executed, a body fold 16 of height hW is generated. When the blank holder pressing force is fixed and forming is executed, a flange fold is generated in case of a comparatively low pressure value or below, and also, a body hold is generated from the vicinity of a specific forming process. On the other hand, according to a forming method by which forming is executed by small blank holder pressure from the beginning of forming, and thereafter, the blank holder pressure has been increased suddenly within a range in which it is not ruptured, a formed part in which no body fold occurs at all is obtained. In such a way, forming defects such as a rupture and a fold, or a surface strain, etc., are prevented.
