Title: Tracking servo system in reproducing system of video signal
Inventor: NAGANO MASAHIKO
IPC: G11B5/588
Filed: 1982-10-12
Abstract: PURPOSE:To attain excellent servo with a simple constitution by recording plural frequency pilot signals at each one track sequentially by each kind together with a video signal and controlling the system so as to obtain equal pilot signal levels extracted at both ends of a heat at reproduction. CONSTITUTION:One kind of the pilot signals f1, f2, f3 is recorded at each revolution of a disc 1 at recording together with a video signal sequentially. The signals f1, f2, f3 are converted into a DC at detectors 6, 7, 8 and applied to differential amplifiers 9, 10, 11. The output of the differential amplifiers 9, 10, 11 is a signal in response to the level difference between the two pilot signals, and when it is positive, it means that the head 2 is deviated at the outside of the disc 1. Gate circuits 12, 13, 14 are switched at each revolution by gate pulses G1, G2, G3 in synchronizing with the revolution of the magnetic disc 1 as shown in Figs. a, b, c and only one is selected. A signal representing one pair of level differences such as pilot signals f1, f2 of a track on which both ends of the magnetic head 2 are brought into contact at normal reproduction is switched at each revolution of the disc 1 and selected sequentially to be a control signal Sc. Thus, the tracking is controlled by controlling the position of the magnetic head 2 so as to make almost zero the signal Sc.

IPC: H01F27/30
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To provide a low cost stationary inductor without deterioration of short-circuit mechanical strength of winding and also improve the long-term reliability of the same stationary inductor. SOLUTION: An installation interval of spacers 5 among the coils is changed depending on circumferential direction distribution of an axial direction generating force of a winding. At the internal diameter side winding, the installation interval of the spacer 5 is set wider at the area near the position Pin within the window of iron core having a smaller axial direction generating force in comparison with that at the position near the position Pout at the outside of window of the iron core. Namely, the spacers 5 among coils are arranged to satisfy the relationship θin>θout when the spacer installation interval at the position in the window of iron core is defined as θin and spacer installation interval at the area nearest to the tank at the outside of window of the iron core as θout.  An interval between the positions Pin and Pout is determined so that the surface pressure of spacer 5 in each position in the circumference direction becomes equal or becomes the value within the predetermined deviation depending on the distribution of generated force.

Also, according to a constitution in which a film surface exists by providing separately the light split member, the lens 4 serves as a photographic lens, too, and goes to a focus detecting device of a TTL system. Accordingly, this device has a good focusing accuracy, and it is not influenced by a contrast of the object to be photographed.

IPC: B41J15/16
Filed: 1989-07-12
Abstract: PURPOSE:To ensure that a recording surface is accurately fed forward and backward by moving a sheet forward and backward and also moving a pen carriage to the right and left. CONSTITUTION:A support bar 16 is introduced into a hole 15 in the center of each roll paper 14 wound in two rolls so that the start end, and rear end of a long sheet 30 used for the roll paper are continuous. Consequently the two roll papers 16 are supported in such a manner that these papers rotate with the support bar 16. Then the support bar 16 is rotated forward and backward, and the sheet 30 is left slack downward almost in a U form. After this, the sheet 30 is moved forward and backward on a recording surface 12, and the degree of slackness in the sheet 30 is detected by photosenesrs 54, 56 on an adjustment device during the cutting process of the surface of the sheet 30 using a cutter 10 mounted on a pen carriage 60. Next, a motor 24 for a drive device is rotated forward and backward to allow forward and backward rotation of the support bar 16 of a support device together with the roll paper 14 around the support bar. Thus the slackness of the sheet 30 which extends before and after the recording surface 12 is adjusted.

Title: Optical disk reproducing device
Inventor: INOUE TAKASHI
IPC: G11B7/005
Filed: 1987-07-17
Abstract: PURPOSE:To detect the peak position of a reproducing signal with simple constitution by obtaining an amplitude detecting signal and a zero intersecting signal from a differentiating signal of the reproducing signal from an optical disk and extracting the zero intersecting point after the amplitude detection. CONSTITUTION:The reproducing signal from an optical head 2 amplified by a preamplifier 3 is differentiated by a differentiator 4. This differentiating signal is inputted to a comparator 5 and another comparator 7. In the comparator 5, the amplitude detecting signal (c) is obtained by binalizing the differentiating signal by way of comparing with a reference voltage (b) from a reference voltage generating circuit 10, which is higher than an AC-like zero level of the differentiating signal. In the other comparator 7, the zero intersecting signal (d) is obtained by binalizing the differentiating signal by way of comparing with the AC-like zero level of the differentiating signal as a reference voltage. In a zero intersecting point extracting circuit 11, only the zero intersecting point which exists immediately after the signal (c) is extracted out. By this method, the peak position of the reproducing signal can thus be detected with simple constitution.
