Title: Fixing roll construction
Inventor: RICHIYAADO JIYOOJI RABONBAADO
IPC: G03G15/20
Filed: 1990-04-23
Abstract: PURPOSE: To join the core and the end cap of a fixing roll with ease and at a low cost by forming a hollow part to the end cap so that a hollow supporting member fused by friction welding flows in to fit the end cap and the hollow supporting member to each other. CONSTITUTION: Steal end caps 125 and 130 are friction-welded to an aluminium cylindrical fixing role tube 120. For example, at the time of placing an end cap 125 in a collet, holding the fixing roll tube 120 so as not to move, rotating the collet by the inertia of a fly wheel and gradually moving the fixing roll tube 120 to be in contract with the end cap 125, the fixing roll tube 120 is fused because of the friction of both and flows into the escaping part 127 of the end cap. Then the fused state of aluminum continues in a short time, the aluminum is solidified and the movement of the end cap is stopped. Thereby a method for joining the end cap to the fixing roll tube at high cost effectiveness is obtained.

Title: Circuit device for controlling warp beam driving apparatus of warp knitting machine
Inventor: BUORUFUGANGU YAAN
IPC: D04B27/22
Filed: 1991-05-14
Abstract: PURPOSE: To prevent an excessive acceleration and deceleration of a warp beam-driving device by changing the degree of amplification controlled by a control signal calculated from a measured value and a target value by a comparator, so as to be proportional to the diameter of the warp beam. CONSTITUTION: A pressure roll 7 is pressed to a warp beam 1 by a swingable arm 8, and an amplifier 21 is controlled by a controlling signal introduced from a measured value and a targeting value by a comparator 15. When the diameter of the warp beam is comparatively large, a swing signal generator 16 generates a swing signal so that the amplitude of the amplifier may be controlled to a lower value than that of the corresponding swing of the swingable arm 8. When the diameter of the warp beam is reduced, the swingable signal generator emits the swingable signal for increasing the amplitude of the amplifier.

Title: Method for connecting fluorinated resin pipe
Inventor: SADAKATA TAKAYUKI
IPC: B29K27/12
Filed: 1987-05-02
Abstract: PURPOSE:To efficiently connect piping using generated friction heat, by engaging a socket made of a fluorinated resin with the piping made of the fluorinated resin and rotating said socket at high speed. CONSTITUTION:The end parts of fluorinated resin pipings 10, 10' to be connected are inserted in a socket 11 having an inner diameter closely brought into contact with the outer diameter of each of the pipings. The rotor 12 of a welding jig is fixed to the outer periphery of the socket 11 and a stator 13 is further mounted to the rotor 12 so as to fix the pipings 10, 10'. A current is allowed to flow to the coil 15 of the stator 13 and a rotary magnetic field is generated to rotate the rotor 12 and the socket 11 at a high speed. As a result, friction heat is generated on the outer peripheral surfaces of the pipings 10, 10' and the inner peripheral surface of the socket 11 to melt both surfaces. When the current supplied to the coil 15 is stopped, the rotation of the rotor 2 is stopped and the generation of the friction heat is eliminated and, therefore, the molten part is cooled and solidified, and the pipings 10, 10' and the socket 11 can be fused and connected.

Title: Noise reduction circuit for video signal
Inventor: HAYASHI TSUNEAKI
IPC: H04N5/21
Filed: 1990-04-24
Abstract: PURPOSE:To reduce large input noise by using a spatial filter in real time when movement exists in an input video signal to increase the resolution timewise and applying timewise processing when no movement exists to improve the resolution in the spatial direction. CONSTITUTION:A mean value and a median or the like for 9 picture elements around a prescribed picture element are obtained from an input video signal V1 from a terminal 10 by a 2-dimension spatial filter 13. A difference between a filter output Vn and a signal Vn-1 stored precedingly in a memory 14 is detected by a movement detection circuit 15. When the absolute value of the difference is large (movement is in existence), a changeover circuit 11 is thrown to the position of a filter 13, and an adding mean circuit 24 applies arithmetic mean to a data with less number of times to the utmost and outputs the result. When the absolute value of the difference is small (movement is less), the changeover circuit 11 is thrown to the position of an input terminal 10, and the signal V1 is fed to the adding mean circuit 24, in which adding mean as many as possible number of times if implemented and the result is outputted. Thus, the changeover of the changeover circuit 11 and the sum of the adding mean circuit 24 are controlled in response to a variable of a movement detection circuit 17 thereby reducing noise in the video input signal effectively.
