Title: Converter location deciding method on disk by corelation and device
Inventor: JIERARUDO RII UEISUFUENINGU
IPC: G11B20/10
Filed: 1990-09-28
Abstract: PURPOSE: To make it possible to precisely determine a converter position with respect to a disk by including a stage of reading out a phase error sample and a stage of alternately associating rough position signals and fine position signals in such a manner that the rough position signals and the fine position signals correspond to the same tracks on a disk. CONSTITUTION: Track ID(track identification) information is associated with position error sample information, by which the mismatching between the track boundaries determined by the track ID information and the track boundaries determined by PES (position error sample) fields is averted. As a result, a servo control processor 24 is capable of precisely determining the position and speed of a converter 14 event at a high radiation speed by using the bit of the digital synthesized PES signal together with the track ID.

Title: Plate thickness measurement method for plate transparent body
Inventor: YAMAUCHI HIDEO
IPC: G01B11/06
Filed: 1993-10-19
Abstract: PURPOSE:To measure a plate thickness precisely even when the position of transparent plate is displaced or it is inclined by correcting an apparent plate thickness of the transparent plate to be measured by a correction value found by using the transparent plate whose plate thickness is previously known. CONSTITUTION:In the first place, the transparent plate 1, whose plate thickness is previously known, is set in the predetermined position, and a reflecting mirror 3 is rotated so as to scan a light beam from a light source 2. An apparent plate thickness is found by an operation device 7 on the basis of a time leg between the arrival of a light beam reflected on the front face of the transparent plate 1 and the arrival of a light beam reflected on the back face of the transparent plate 1 in the first light receiving device 6, and a difference between the apparent plate thickness and an actual plate thickness, in other words, a correction value is found. In the second place, the time lag between a light beam reflected on the front face of the transparent plate to be measured 1 and a light beam reflected on the back face of that is found by the operation device 7 in the light receiving device 6, and an apparent plate thickness is found. Then, arrival times of light beams to the light receiving device 6 and to the second light receiving device 10 are found. And consequently, the apparent plate thickness is corrected by finding the previously stored correction value on the basis of these two times by the operation device 7, so that plate thickness without any error is found.

Title: Bar-code reader
Inventor: SHINODA ICHIRO
IPC: G06K7/10
Filed: 1989-10-05
Abstract: PURPOSE:To accurately demodulate a bar-code by demodulating a guard bar when a margin checking means detects the existence of a white regular margin on the outside of at least one guard bar at the time of continuously reading out the bar-code in the order of a guard bar, a center bar and a guard bar. CONSTITUTION:At the time of thoroughly reading out the bar-code like a beam B1 from the sufficiently existing side of the white margin to the absence side of a white margin, the existence of the initial white margin is confirmed by a margin checking part 1 and a margin existence flag F0 is turned on. Then, a guard bar checking part 2 detects the guard bar GB and a character constitution checking part 3 checks whether determined character constitution consisting of two white bars and two black bars of 7-module width is formed or not. When a check OK signal for the character constitution is outputted, a sequence control part 6 outputs a demodulation execution signal to a demodulating part 5. Thus, the bar-code can be accurately read out.

Title: Direct modulation method for semiconductor laser
Inventor: EMURA KATSUMI
IPC: H01S5/06
Filed: 1990-09-28
Abstract: PURPOSE:To obtain flat frequency characteristic covering from the lower range to the higher range even in the case of conducting direct frequency modulation or direct phase modulation by applying a modulation signal both to the active region and phase control region in a multielectrode semiconductor laser to modulate the oscillated light beam. CONSTITUTION:In an example of a three-electrode DBR-LD providing a phase control region not including active layer in addition to the active region within a semiconductor laser, the 3-electrode DBR-LD oscillates by applying a bias current to the active region and controls oscillation wavelength by applying a current to the DBR region. When the FM modulation is conducted only in the active region, the characteristic as shown by a broken line can be obtained. Meanwhile, when modulation is executed in the phase control region, efficiency thereof is changed by a bias current of the phase control region but the characteristic as shown by a chain line of the figure can be obtained. Therefore, when a modulation signal is applied to both active region and phase control region while a bias current of the phase control region is adjusted, almost flat FM modulation characteristic covering the frequency range from 1kHz to 5GHz which is important for practical use can be obtained as shown by a solid line.

Filed: 1988-10-19
Abstract: PURPOSE:To improve electromagnetic conversion characteristics and traveling durability by subjecting a ferromagnetic metal powder showing an adsorption of stearic acid at 5.0X10<-6>mol/m<2> or more to surface treatment with specific triazine dithiol derivatives, dispersing the powder in a resin having specific polar groups and forming a magnetic layer with the powder and fatty acids. CONSTITUTION:The ferromagnetic metal powder showing the adsorption of stearic acid at 5.0X10<-6>mol/m<2> or more is subjected to surface treatment with triazine dithiol derivatives expressed by formula I and dispersed in such a resin having polar groups expressed by formula II to form the magnetic layer with fatty acids. In formulae I and II, X represents R1O- or the like, R1 and R2 represent alkyl groups, etc., having 1 - 18 carbons, M1, M2, M, M', R3 and R4 represent H or the like. By using a combination of the triazine dithiol derivatives and the resin having polar groups, the ferromagnetic metal powder disperses well and the obtained magnetic layer has a smooth surface. Moreover, the maximum magnetic flux density and the squareness ratio of the magnetic layer increase, which results in good electromagnetic conversion characteristics and excellent traveling durability of the medium.

Title: Copying machine
Inventor: MORIKAWA TAKESHI
IPC: G03G21/14
Filed: 1990-09-28
Abstract: PURPOSE:To allow the formation of always a specified margin part by adjusting the operation timing for electrification or destaticization in order to form the margin part at a certain copying magnification. CONSTITUTION:The distance between a resist roller 17 and a transfer position (distance between A and B) is designated as LAB and the circumferential length (distance between D and B) on a photosensitive body 11 between an exposing position and the transfer position is designated as LDB. The front end of the image on the photosensitive body 11, then, coincides with the front end of the paper in the transfer position if the resist roller 17 is turned on upon arrival of the front end of the image on the photosensitive body 11 at the E position where LEB=LDB is attained. The resist roller 17 is necessitated to be turned on after the time LDB/VP when the image on the photosensitive body 11 moves between LDB from the point of the time when the slider of the optical system arrives at the front end of the image. The exposing position is, however, changed by the copying magnification and, therefore, the adjustment is made with the exposing positions at the unmagnification and the max. magnification. The exposing position is adjusted as the positions changing proportional at other copying magnifications.
