Title: Patrol type noise eliminator
Inventor: KATAGIRI TOSHIYUKI
IPC: H04N5/21
Filed: 1987-12-29
Abstract: PURPOSE:To suppress the occurrence of an after image at a transition period when a video signal is switched by restricting a patrol type noise reduction processing in a fixed period when an object of which noise is switched over to the video signal of which hysteresis is different. CONSTITUTION:When the inputted video signal is switched by switching a change-over switch 12, subtraction input for a subtracter 4 is cut off by a change-over switch 14 until the fixed time set to a delay circuit 13 goes by after the inputted video signal is switched. Due to that, the video signal supplied to an AD converter 2 is passed through a DA converter 7 as it is and the noise reduction processing is actually stopped together with the output cutoff of a limiter circuit 6. Thus, the occurrence of the after image caused by the addi tion of signals which do not have video correlation each other can be prevented before.

Filed: 1990-11-29
Abstract: PURPOSE: To optimize the setting time of a magnetic head on a track after seek by determining a velocity increment, which is added to a required speed while a servo head is moving in one direction and which is subtracted while in the opposite direction, and thereby equalizing the real velocity in both directions. CONSTITUTION: Each track 19, 20,... on a disk 12 is allotted to one of the plural concentric circular regions; a velocity increment is determined such that, with a head 28 moving in one direction by crossing the disk 12 in relation to each region, velocity increment is added to the required velocity determined from a required velocity profile, and that with the head 28 moving in the opposite direction, the velocity increment is subtracted from that velocity, so that the real velocity is equalized in both directions. Then, all seek in one direction in a specified region is carried out in accordance with the compensated velocity requirement obtained by adding the velocity increment, while all seek in the opposite direction is carried out by subtracting the velocity increment. Thus, the settling time of the head 28 is optimized on the track of the disk 12 after seek.

IPC: B41J29/38
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To set up optimum control information including items which can not be inputted in a printer. SOLUTION: When a user input control information for the printer 6, the information is stored in a user information storing part 2. A combination information storing part 3 stores all combinations of control information items to be set up by the user and the values of items which are selected as items optimum to the combinations but can not be set up by the user as previously set values. An information comparing part 4 compares the values stored in the storing part 2 with the values stored in the storing part 3, and at the time of detecting a coincident combination in the contents of the storing part 3, stores the value in a printing information storing part 5 and transmits the value to the printer 6. Consequently an optimum value can be selected even from items disabled from being selected by the user and sent to the printer 6.
