Title: Magnetic disk device
Inventor: SUGIMOTO YUKIMASA
IPC: G11B21/08
Filed: 1987-07-30
Abstract: PURPOSE:To shorten effective seek time by starting immediately a seek action without waiting for a next step pulse when a pulse detecting means detects that even one pulse is inputted. CONSTITUTION:In the condition of waiting for a seek instruction in a position determining mode, a micro-processor 22 monitors the output of a pulse detecting means 25. When the input of the step pulse is recognized, the micro-processor reads the output of a subtracting circuit 24, realizes a seek direction and a remaining seek length, sets a target speed according to the remaining seek length in a DA comparator 19, and switches a switching circuit 16 to a seek mode. Thereafter, the micro-processor 22 repeats an action to see the remaining seek length and reset the target speed into a DA converter. The seek is executed without knowing a final target cylinder, but since the remaining seek length corresponding to the newest target cylinder is always calculated and the target speed is modified, there is no problem to continue the seek action. Thus, the effective seek time can be reduced.

Title: Method and device for binarizing image data
Inventor: WAJIMA HIROSHI
IPC: G06T5/00
Filed: 1997-07-17
Abstract: PROBLEM TO BE SOLVED: To prevent an unnecessary background part from being binarized by counting pixels of gradations of density by windows where image data are divided and setting density between double-humped high-density and low-density areas as a discrimination level. SOLUTION: When an image begins to be binarized (a1), division into windows less than the pixels of one screen is performed and they are set (a2). Then image data having gradations of density included in window areas are extracted (a3) and a histogram is generated to calculate the feature quantities of the windows (a4). At this time, the upper and lower limit values of a prescribed density range are set and the pixels included in the density range are counted (a5). The number Fn of pixels is compared with a predetermined pixel number fc (a6) and when Fn<Fc, the window is judged to have double humps, thereby binarizing the pixels by discriminating the density level by the pixels by using the set discrimination level Thw. Consequently, noise components of the background part are removed.
