Abstract: PURPOSE:To shorten a picture forming time for the first picture after the attachment of a cassette irrespective of loadage by providing a sheet lifting means operated by the signal of a controller based on the signal from a sheet detecting means. CONSTITUTION:When the uppermost one of sheets S... is lifted up to a position to close partially openings C4, C5, a light beam sent from a luminescent element 39 toward a light receiving element 40 is varied with sheets S.... Thus, the detecting signal is supplied to the input of a microprocessor unit 41 to turn off a clutch and stop a cam member 31. Thus, the uppermost sheet S on a intermediate plate 34 is located by a predetermined distance beneath a paper supply roller 27. Then, a lifter 6 is gradually lifted and the sheet S reaching a predetermined paper supply position is detected. Then the lifter 6 is blocked from being lifted up. Then, if necessary, a paper supply roller 27 is rotated so that the sheets S... are supplied from the uppermost one toward a copy section.

Title: Image pickup device with vibration correcting function
Inventor: SATOU TAKENORI
IPC: H04N5/232
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To permit optimum image shaking correction to image shaking caused by vibrations. SOLUTION: A frequency to be generated by camera shaking is 10 Hz or the like generally and shown in the figure as a signal S5 expressing the amplitude of image shaking. Besides, a vertical synchronizing signal is 60 Hz in the case of NTSC system, for example, and shown in the figure as VD. When the camera shaking frequency and shutter speed are considered, it is effective to find a correction amount from the amount of image shaking near the middle of time for storing image pickup information in one field, for example. In the storage time of 1/60 sec, for example, the correction amount is found from an amplitude L1 of shaking at the timing of C1 and the correction of the next field is reflected with this amount. The timing to operate this correction value is made variable and corresponding to the shutter speed, the correction value can be always calculated at the optimum timing.

Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To improve the precision in the judgment in a line by grading yarn by using not only the data on weight and visual inspection for a wound bundle but also the quality data of the yarn to be worked into the wound bundle. SOLUTION: A target value TO of yarn tension, a target scope with suitable upper and lower margins, and an allowance scope with upper and lower margins of a limit which is allowed from the target value TO are input in a tensile force control part in advance to adjust contact pressure of a false twister so that untwisting tensile force T is in this target scope (Tu<T<Td). If abnormal untwisting tensile force T which exceeds the allowance scope is detected during this control (T>Tmax, T<Tmin), the tensile force value and a period of the detection (yarn length L1) are input into a winding control part of a winding control mechanism every time the abnormality is detected. Moreover, even when the untwisting tensile force T exceeds the target scope, the tensile force value and a period of the detection (yarn length M1) are detected.  The yarn is graded for the quality of draw false-twist working based on the target scope and a degree which exceeds the allowance scope.

Further, the recording is started from the position of the effective information to be detected. Thus, the omission of picture information cannot be generated in both edge parts of a recording width as a conventional case, and the effective picture information can be completely recorded.
