Title: X-ray photographing apparatus
Inventor: OOTA SHINICHI
IPC: G03B42/02
Filed: 1978-12-27
Abstract: PURPOSE: To closely contact an X-ray film to an intensifying screen only at the X- ray photographing by controlling the close contact of the X-ray film to the intensifying screen by the plural cams interlocking to a film conveying motor.  
     CONSTITUTION: When the X-ray film being conveyed is detected with a detector 11, the output of a controller 12 inverts and a transistor 32 conducts, causing a motor 10 to run. A switch 13 is then closed by a cam 7 to open an AND gate 28. The high-level output through this gate 28 causes a transistor 31 and transistor 32 to conduct and nonconduct respectively to stop the motor 10. A switch 14 is then closed by a cam 8 to cause the transistor 31 to nonconduct. When a photographing switch 16 is closed in this state, the transistor 31 is reconducted by the high-level output through an AND gate 26 to run the motor 10. A pressure plate 4 is then pressed by a cam 6 to contact an X-ray film 3 closely to an intensifying screen 4. At the same time, an exposure signal is generated from an AND gate 29, thus the good photographing by the film whose emulsion does not cause fit to the intensifying screen through the close contact at the unnecessary time is accomplished.

Title: Rolling method for preventing bend of hot pipe
Inventor: KAJIYAMA FUYUHIKO
IPC: B21B17/14
Filed: 1992-06-24
Abstract: PURPOSE:To drastically reduce the bend defect of a hot pipe by rolling by increasing the circumferential speed of roll of a sizer mill on the side of upper rolls than that on the side of lower rolls. CONSTITUTION:At the time of routine rolling, a temp. on the side of the upper part of the hot pipe is higher and that on the side of the lower part is lower. So, by increasing the circumferential speed on the side of the upper rolls than that on the side of the lower rolls, fine elongation is imparted to the side of the upper part as compared to the side of the lower part, the temp. difference between the upper and lower rolls is cancelled by this fine elongation and the bend of pipe is reduced. As the method for changing the circumferential speed of roll, a method that the revolving speed of roll is changed may be allowed, but it is simpler to make a difference between the barrel diameters of the upper and lower rolls. In this way, even when there is the difference between the cooling temps. of the upper and lower rolls, by making the difference between the circumferential speeds of the upper and lower rolls, the bend defect of the hot pipe can be reduced.

Title: Backlash correcting device for position control device
Inventor: KAZETO HIROHIKO
IPC: B23Q15/00
Filed: 1988-07-04
Abstract: PURPOSE:To move a machine position in a track close to a command position by discriminating the inversion of a direction by using a position control model and switching a backlash correcting variable to two steps. CONSTITUTION:Even when a command position P0 generated from a command position generator 1 is inverted at a point T0 of time, a correcting position Pc obtained by adding a backlash correcting variable outputted from a backlash correcting device 15 to the position P0 is equal to the position P0 and the position Pc is set up to a position obtained by adding a backlash correcting variable BL2 to the position P0 from a point T0' of time when a machine position inversion timing estimater 12 discriminates the timing of the inversion of a machine position PM. Consequently, a motor 7 shortens the backlash, and from the time T1' ending the backlash shortening, the correcting variable BL2 is changed to a backlash correcting variable BL1. Although a machine 9 is stopped during the period between T0' and T1', the machine 9 starts to be driven from the time T1' and is moved with the delay of practical backlash from a motor position PF.
