Title: Method for eliminating uneven thickness of seamless steel pipe
Inventor: TOGASHI FUSAO
IPC: B21B37/78
Filed: 1982-07-05
Abstract: PURPOSE:To improve hot online the dimensional accuracy of a seamless steel pipe by determining the helix angle in the axial direction of a thickness deviation from the fluctuation in the wall thickness of a blank pipe detected during hot rolling, estimating the factor at which the thickness deviation arises in accordance with the detected helix angle and eliminating the thickness deviation. CONSTITUTION:The relation between the factor for thickness deviation and a helix angle beta corresponding to the same is beforehand determined by experiment in the production of a seamless steel pipe by a Mannessman plug mill process. The line connecting the max. wall thickness parts in the respective sections of the pierced blank pipe 4 is the straight line grading at the helix angle beta in this case. The fluctuation in the wall thickness in the longitudinal direction of the pipe 4 is detected during actual hot rolling, and the detected fluctuation in the wall thickness is analyzed to calculate the helix angle beta. The factor at which the thickness deviation arises is estimated by using the relation determined beforehand and the thickness deviation is online eliminated.

Title: Automatic sheet feeding device
Inventor: HAYAKAWA KIMIAKI
IPC: B65H7/04
Filed: 1982-07-07
Abstract: PURPOSE:To prevent failures in both separation and conveyance from occurring as well as to aim at the promotion of highly efficient copying operation, by detecting the position of an arm of an auxiliary roller on a loading tray that varies with the thickness of a pile of loaded copies, while separating and feeding them in time of exceeding the limits of loading capacity. CONSTITUTION:A paper feeding auxiliary roller 7 is secured tight to an auxiliary roller shaft 8 and rocks centering on a paper feed driven shaft 3 by means of an auxiliary roller arm 9. Likewise, the auxiliary roller 7 rotates together with the driven shaft 3 via a timing belt 10. In addition, an arm position detecting sensor 62 secured to a paper feeding angle 61 where the driven shaft 3 is supported detects the vertical position of the auxiliary roller arm 9. When copies of more than the specified number of sheets are loaded on a paper feeding tray 1, a plunger 48 is turned to ON and the sensor 62 therefore detects the position of the arm 9 at a point when the roller 7 descends on the copy and outputs a drive stopping signal to a paper feeding drive control unit. With this, a paper feeding drive mechanism stops its paper feeding motion at once.

Filed: 1978-09-22
Abstract: PURPOSE: To reduce the size and simplify the construction of a power steering system, by supplying a linear motor with current changeable in accordance with the steering direction and force of a steering wheel.  
     CONSTITUTION: A rack 4 of a steering link 3 is engaged with a pinion 7 of an input shaft 6 connected to a steering wheel 5. As the steering wheel 5 is turned, the steering link 3 is transferred to control the direction of wheels 1. A linear motor 8 is used as a supplementary driving power for the steering action. A turn the steering wheel 5 generates a torsion in the shaft 6 which is determined by the turning force and the grounding resistace of the wheels 1 and a current flows in a slider 9 in proportionate with the torsion. Since a stator 10 is previously magnetized with a preset current, a driving force for controlling the link 3 is generated in accordance with the direction and amount of the current flowing in the slider 9.

Title: Detection circuit for vertical synchronizing signal
Inventor: KOBAYASHI MASAHARU
IPC: H04N5/932
Filed: 1978-09-27
Abstract: PURPOSE: To obtain a signal detection circuit which generates no timing error, etc., even if a drop-out would occur by making a shift register, etc., generate pulses, synchronizing with vertival synchronizing pulses, corresponding to a vertical synchronous pattern.  
     CONSTITUTION: Vertical synchronizing pulses trigger multivibrator 26 to clear the contents of shift register 15, thereby detecting a vertical pulse passing through OR circuit 14. Once they are cleared, on the other hand, register 15 with stages corresponding to a vertical synchronous pattern counts clocks synchronizing with the vertical synchronous pattern from its initial state, thereby outputting clocks synchronizing with vertical pulses. Those pulses are applied to register 15 through gate 14 and register 15 continues to count them cyclically. Therefore, if any vertical pulse is not detected in a fixed period, register 15 is not cleared and pulses synchronizing with vertical synchronizing pulses are detected in accordance with the vertical synchronous pattern. As a result, even when a vertical pulse is absent due to a drop-out, etc., the vertical pulse is substantially detected to prevent the generation of a timing error, etc.

Abstract: PURPOSE:To shorten a measurement greatly by correcting the position error and collimation error of an image photographed by a two-dimensional area sensor on a screen according to the difference between the known three- dimensional distribution state of reflected light from a standard plate and the distribution state of the sensor. CONSTITUTION:When a light source L illuminates and reflected light which is reflected by a sample S is measured on a spherical surface A having its center at an incidence point O, there is no error, but the light is projected actually on a plane B, so the position error on the screen 14 is generated. The collimation error of a two-dimensional area sensor 15 is corrected according to the difference between the three-dimensional distribution state of reflected light from, for example, an MgO powder plate, a BaSO4 plate, etc., and the distribution state photographed by the two-dimensional area sensor 15 similarly to the sample 10. For the purpose, the luminous intensity, brightness distribution, or relative refractive index distribution of the reflected light can be measured in real time by using the standard plate, e.g. the three-dimensional luminous intensity distribution state and brightness distribution state of the reflected light from the sample are measured in real time.
