Title: Error dispersion circuit
Inventor: MATSUNAGA SEIJI
IPC: G09G3/28
Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To conduct an error dispersion process without disturbing the ±balance of the amount of errors even though the ± balance of an output signal E/2 is disturbed by shift operation of the coefficient multiplier which output a signal E/2 that is made by 1/2 weighting the amount of error E. SOLUTION: The circuit is provided with adding circuits 14 and 16 which add reproducing error of vertical and horizontal directions to video signals so as to obtain spread output signals, an error amount confuting circuit 20 which operates the difference between the spread output signals and the setting value for PDP, delaying circuits 24 and 26 which delay the operated value E, coefficient multiplier 28 and 32 which multiply a 1/2 coefficient to the delayed output and output the results to the circuits 14 and 16 and odd number detecting circuits 30 and 34 which detect whether the outputs of the circuits 24 and 26 are odd number or not and output data '+1' to the circuits 14 and 16. When a least significant bit '1' disappears during the shift operations by the multipliers 28 and 32, the ± unbalance is corrected for by adding the data '+1'.

Title: Method for bonding color separation filter
Inventor: OGURA YASUTSUGU
IPC: H01L31/0216
Filed: 1982-09-07
Abstract: PURPOSE:To adhere a color separation filter to a substrate uniformly without being affected by the local difference of UV transmittance, by forming the color separation filter on an adhesive layer bonded to the substrate, irradiating it to harden a part of it, and hardening all the adhesive layer with heating. CONSTITUTION:The color separation filter is set, then, a solid-state image pickup element is set, and fixed by vacuum suction.

Abstract: PURPOSE:To know the recording end state in a clear and assured way and to prevent previously the subsequent undesired recording or other operations, by providing a record finishing detecting means for plural circular recording tracks. CONSTITUTION:A titled device consists of following parts. A magnetic head 8 is fed out one more step by a head shifting mechanism 23 after the recording is finished with the final recording track by the head 8. Thus a switch part 68 is driven to cut off an electrical contact. A press stage part presses a projection provided at an end 69a of an approximately L-shaped contact arm 69 which forms a contact of one side of the part 68 when one step is fed after the recording is finished to the final track. As a result, an electrical contact is cut off between a contact part 70 and the arm 69 which form the part 68.
