Filed: 1988-10-27
Abstract: PURPOSE:To make it difficult for the slip of a part of driving wheels to develop into a slip of all the driving wheels by letting the motor current given to a current control device be the value found by the maximum value of each motor current detector resulting from multiplication by the number of motors. CONSTITUTION:In order to detect the motor current of induction motors 71 to 74 separately, current detectors 81 to 84 are provided. The current signal detected by these current detectors is inputted into a coefficient multiplier 12 by selecting the maximum value from among the signals with a maximum value selection circuit 11. It is then multiplied by the number of motors (4 sets) and fed back to a constant current controller 21. Here, let the motor current of each induction motor in normal operation be Ii(i=1 to 4), among which let the maximum value be Imax   Ii. The relationship by an expression I then holds. Then, even in case the driving wheel coupled with to the 1st (i=1) induction motor slips, as the feedback signal is 4.Imax, there will be almost no change to the feedback signal with idling and less danger to the spread of slip.

Title: Non-linear video editor
Inventor: KAJIMOTO KAZUO
IPC: H04N5/765
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To provide a device, with which original image editing can be restarted at any arbitrary time point even when video data in a video recording part are erased by providing clip managing information with a material presence/absence identifier and preserving the edited result by reloading the material presence/absence identifier through a material deleting part, when deleting video data. SOLUTION: Inside the clip managing information, the material presence/ absence identifier is provided for identifying whether the video data indicated by the clip managing information is present or absent in a video recording medium. Then, even when the video data are deleted from the video recording medium, non-linear video editing operation can be performed as usual only by deleting the video data and setting the material presence/absence identifier without data. A material deleting part 156 deletes the video data in the video recording medium and sets the material presence/absence identifier in the clip managing information, corresponding to the deleted video data without data.

Title: Optical pickup device
Inventor: ITONAGA MAKOTO
IPC: G02B13/00
Filed: 1995-09-25
Abstract: PROBLEM TO BE SOLVED: To provide an optical pickup device capable of restraining occurrence of a coma aberration even though optical axes of an objective lens and a correction optical lens are deviated. SOLUTION: This optical pickup device reproduces two kinds of optical disks 2A, 2B having different thicknesses and uses a zero-order diffracted light L1 to reproduce the optical disk having the thickness designed in an objective lens 7 and uses a 1st-order diffracted light L2 to reproduce the optical disk having the other thickness by providing a correction optical element 6 for performing an aberration correction in an optical path. The aberration correcting amount of the 1st-order diffracted light is constituted to be smaller than an aberration generated due to the difference in the thicknesses of the two kinds of optical disks. Consequently, even though the optical axes of the objective lens 7 and the correction optical element 6 are deviated, the increased amount of the coma aberration is made smaller than the increased amount in the case of complete aberration correction.

Abstract: PURPOSE:To enhance the accuracy of tracking and to enable the reproduction even with a commercially marketed CD player by providing a recording layer which allows reading and writing of information with a laser on the grooved tracking guides having the width and depth in a specific range of the surface of a disk-shaped substrate. CONSTITUTION:The tracking guides consisting of grooves are provided on the surface of the disk-shaped substrate 9 and the depth (h) of the grooves 1 is specified to a 200-600Angstrom  range and the width (w) thereof is specified to a 0.3-0.6mum range. The recording layer which allows writing and reading of information by the laser is provided thereon. The grooves 1 of the tracking guides provided with the recording layer are then irradiated by the laser light while the recording medium is rotated at a constant linear speed, by which the recording of the information is executed. The width of the recording pits 3 is narrow and uniform and the bits have high reflectivity if the recording medium is constituted in such a manner; therefore, the accuracy of tracking is high even if reproduction is executed by a 3-beam method of the commercially marketed CD player. Sound jumping, etc., by oscillation, etc., are thus prevented.
