IPC: H04N1/405
Filed: 1996-12-20
Abstract: PROBLEM TO BE SOLVED: To reduce the difference of practical resolutions for respective colors and the difference of highest printable speeds for the respective colors even in the case that the resolutions in a sub scanning direction for the respective colors are different and conversion is performed by making the size of a dither matrix, that is the number of elements, different for every color and also making the printing gradation numbers of respective pixels different for every color. SOLUTION: In this example, in M, Y and K and C, the numbers of sub matrixes are respectively made different. The values of dither elements corresponding to the respective pixels (0-7 in the case of K and C and 0-3 in the case of M and Y) are added first. In the case of exceeding the maximum value of image data by addition, setting is performed at the maximum value. Thereafter, the gradation data of the respective pixels cancel low order bits for a prescribed bit number. In this case, the bit number to be rounded down is different for the respective colors and depends on the number of the elements of the dither matrix. The bit number remaining there decides the printing gradation number of the respective pixels.

Filed: 1992-12-22
Abstract: PURPOSE:To improve the reliability of a communication conference by storing a state just before interruption when communication is unexpectedly interrupted, and automatically recovering the state just before the interruption when an opposite terminal is connected again. CONSTITUTION:When the communication is unexpectedly interrupted by generating power failure at the opposite side terminal, a line is disocnnected and an interruption instruction message comes to a conference application control part but it is judged from a reason code in this message whether the fault is generated at the opposite side terminal or not. When the fault of the opposite side terminal is regarded, a RAM 4 stores the state just before the interruption message comes, and image data stored in a VRAM 11 are stored in an image memory 5 as a file. Next, when the opposite side terminal is recovered, the opposite side terminal originates a call to a present terminal, and the communication is started again. At such a time, the sequence of communication is decided so as to get the state stored in the RAM 4. Then, when a confirm signal is received from the opposite side terminal, the file of image data stored in the image memory 5 is transmitted to the opposite side terminal.

Title: Optical head device and method for regulating inclination angle of its objective lens
Inventor: YANAGISAWA KATSUSHIGE
IPC: G11B7/12
Filed: 1999-12-02
Abstract: PROBLEM TO BE SOLVED: To prevent the deviation of the principal point of an objective lens of an optical head device from the center of an aperture diaphragm by regulating the angle of inclination of the objective lens. SOLUTION: The objective lens 5 of the optical head device is adhered and fixed to a spacer 11 attached with the aperture diaphragm 112 by a first soft adhesive 12. This spacer 11 is adhered and fixed to a spacer sliding adhesive surface 92 of a lens holder 9 by a second adhesive 13. Even if the angle of inclination of the objective lens 5 is regulated by sliding the spacer 11 along the spacer sliding adhesive surface 92, the relative positions of the aperture diaphragm 112 and the objective lens 5 are fixed and therefore the occurrence of the deviation therebetween is averted. Since the objective lens 5 is adhered and fixed to the spacer 11 by the soft adhesive 12, the occurrence of distortion, etc., in consequence of the curing shrinkage and thermal deformation of the adhesives is averted as well.

Title: Dynamic pressure bearing
Inventor: YOSHITSUGU TAKAO
IPC: F16C17/02
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To provide a bearing of excellent high rotating speed performance and stably holding lubricating oil by specifying the ratio the width of a dynamic pressure generating groove to the pitch, and the angle of the groove against the rotating direction. SOLUTION: A rotary shaft 1 is inserted into a sleeve 2, two set of dynamic pressure generating grooves 4, 5 are provided at groove angles B1, B2 on the bearing parts 6 of the sleeve 2, and a clearance is kept between the bearing part 6 and the rotary shaft 1 so as to be filled with lubricating oil. By the ratio the width (d) of the dynamic pressure generating grooves 4, 5 to the pitch (e) between grooves, k=d/e, the relation against the groove angles is set as follows: k×sin(B1), k×sin(B2)≈0.1. When squeeze action is generated on the rotary shaft 1 due to unbalance or the like, force applied to the face of the bearing part 6 becomes large at non-groove parts, and lubricating oil is forced to escape toward the grooves 4, 5.  By setting the angles B1, B2 and the ratio (k) in a fixed relation, oil holding property against lubricating oil and discharge of air are improved, and stability at high rotating speed and improvement of the bearing life can be attained.
