Title: Separation failure detector for transfer paper
Inventor: SUDOU TOSHIHIKO
IPC: G03G15/00
Filed: 1980-01-16
Abstract: PURPOSE:To detect the separation failure of transfer paper by emitting light onto a photosensitive drum for a predetermined time since application of at least one of the application of source voltage and the application of a copying machine start signal and comparing the reflected signal and a reference signal in a comparator. CONSTITUTION:Light is emitted onto an electrostatic drum from a light emitting part 7a for at least one of the predetermined time from the time when source voltage is applied and the period while the copying start signal is being applied and the light reflected from said drum surface is received in a photoreceiving part 8a. In these predetermined periods, the voltage (a) is applied to a terminal 18 and to a monostable multivibrator 19, and the pulses (b) enter an OR circuit 20. While there is no transfer paper, the output of a comparator 22 is a low level. When there is transfer paper, this output is a high level and a JAM signal (f) is outputted to a terminal 24, thus even if there are no pulses b2, this level is held by a capacitor 23 and this is held until the paper is removed.

Abstract: PURPOSE: To achieve the simplification of constitution by specifying the material of optical lens.  
     CONSTITUTION: The optical lens is made into the variable focal length lens formed by material which is transparent and has ferrodielectric constant such as potassium sodium tartrate and is connected to a coincidence detector. As a result of this, the images are entered from the subject image to the variable focal length lens in the  two routes of different optical paths and when the double images thereof do not  coincide, the voltage proportional to the non-coincidence distance is generated and  its dielectric constant is changed, by which its focal length is controlled and accurate imaging accomplished. Hence, the need for servo mechanism of moving the optical lens is eliminated and the constitution is simplified and is made fully electronic, resulting in faster response.

Filed: 1991-01-16
Abstract: PURPOSE:To attain the transfer of data with high efficiency and to improve the access efficiency by preventing such a case where a shorter access cycle time is affected by a longer access cycle time. CONSTITUTION:A cycle time comparator 4 compares the cycle time obtained by a 1st cycle time measuring means 2 with the cycle time obtained by a 2nd cycle time measuring means 3. Thus a port of a short cycle time is identified. The outrun control means 5 and 6 stop the progress of addresses of the ports having the long cycle times and advance the progress of addresses of the ports having the short cycle times when the progresses are set in the same direction between the ports of the long and short cycle times and when the progress of the bank address of the port of the short cycle time catches up to the progress of the bank address of the port of the long cycle time. The progress of address at the port of the short cycle time is advanced. Then the stop of progress is canceled for the address of the port of the long cycle time.

Filed: 1995-01-12
Abstract: PURPOSE: To enhance the CN ratio of a signal reproduced through magnetic superresolution by controlling the strength of external field being applied to the surface of a recording medium rotating at high speed depending on the difference of line speed. CONSTITUTION: The reorder/reproducer comprises means 5 for rotating a recording medium 3, a laser beam light source 4 for reproduction, an electromagnet 1 in field applying means, and a field strength control means 2 for controlling power supply to the electromagnet 1. The field strength control means 2 controls the spot size of laser beam on the recording medium 3 to increase gradually in the radial direction of the recording medium, i.e., controls the strength of applying field to increase gradually as the spot of laser beam moves from the inner circumferential region to the outer circumferential region at the time of reproduction. Since the high temperature region in the spot of laser beam irradiating the recording medium can be made constant, difference of line speed due to the rotation of recording medium has no effect on the operation and the CN ratio is enhanced.

Abstract: PURPOSE:To surely execute a detection by constituting the titled pattern by arraying a first pattern which has placed two-frequency signals having each different frequency alternately in the width direction of a track in a two-track period, and a second pattern repeated in an (n)-track period. CONSTITUTION:After reading the data of a sector N in a data sector 4, burst signals 5, 6 are reproduced simultaneously, frequency components f1, f2 of the burst signal 5, 6 are discriminated by a discriminating circuit, and if one signal exists, an amplitude sampling signal of a servo-burst signal is generated.

In this state, the servo-burst signals G, H are not detected, but the servo-burst signals I, J are detected so that the amplitudes of the servo- burst signals I, J become equal. In case an off-track of a +1 track has been generated, the servoburst signal G and J are detected by the same amplitude, therefore, it can be decided that the off-track of the +1 track exists.
