Abstract: PURPOSE:To make color correction without using sum of products operation by changing output value of a threshold value generating means making at least one of three-color signals of an original picture image control signal input of a threshold value controlling means, and making color correction simultaneously when the three-color signals are pseudo-halftone converted. CONSTITUTION:Color separation signals 3 of a color original picture 3 are binary coded at once by a pseudo-halftone processing circuit 40. At this time, a color correcting circuit 80 makes interlocked operation simultaneously and generates binary coded color correction signals 9. When systematic dither process is used for pseudo-halftone processing, inputted chrominance signals C, M, Y enter comparators 204, 205, 206 respectively through signal lines 201, 202, 203, and compared with output of adders 210, 211, 212 for each picture element and converted to binary color correction signals c', m', y'. Three input lines are provided in adders 210, 211, 212, and the content of LUT (look up table) connected two by two is added to the content of threshold matrices 207, 208, 209 and comparison signals are outputted to comparators 204, 205, 206.

Filed: 1995-09-05
Abstract: PROBLEM TO BE SOLVED: To prevent flowing of excessive current into an input side circuit by connecting a diode in parallel to a series circuit of an inductor and transformer control coil provided for power-factor improvement, for suppressing differencial voltage which occurs when input voltage rises sharply. SOLUTION: A diode 14 is connected parallel to a series circuit of an inductor 6 and a control coil N3 of a transformer 7 provided for power-factor improvement, in the direction of charge of a smoothing capacitor 8.

Title: Loading mechanism for optical disk device
Inventor: KATAOKA MASANORI
IPC: G11B17/04
Filed: 1988-10-06
Abstract: PURPOSE:To improve a loading mechanism and to set a medium on the turntable of a spindle motor softly by pressing a supporting plate moved in forward and backward directions forward replying to the upward and downward movement of a carrier with a spring. CONSTITUTION:When a disk cartridge is inserted, the carrier 2 is moved along a guide hole 3a. Since the supporting plate 12 is pressed forward by the spring 15, it stops without moving when the horizontal movement of the carrier 2 is performed. When the horizontal movement of the carrier 2 continued and it enters a descending motion area, the roller 4 of the carrier 2 is abutted with the oblique side part 12b of the supporting plate 12. It is required to move the supporting plate 12 backward to continue the descending motion of the carrier 2, however, since a spring force not moving the supporting plate 12 even when the weight of the cartridge and the carrier 2 are added on the oblique side part 12b is applied advancing forward at the supporting plate 12, no carrier 2 and cartridge drop freely due to their dead weight. Since the descent of the carrier 2 is performed by a force in a downward direction due to the torque of a link, the medium can be loaded softly.
