Title: Air pressure type servo unit
Inventor: ANDO HIROMI
IPC: B60T13/56
Filed: 1992-12-11
Abstract: PURPOSE:To increase a raising quantity of assisting force at the time of requiring a sudden deceleration without enlarging the size thereof by constituting this device so that an on-off valve is opened when a brake pedal is largely operated and thereby compressed air flows into a working pressure chamber via a passage. CONSTITUTION:When a brake pedal is operated in operated in order to secure the normal deceleration, an operation rod 18 moves in an output direction to a valve body 12, while an on-off valve 57 is left closed intact and a breather valve 33 is opened instead, whereby the atmosphere is introduced into a working pressure chamber 17, assisting the input of this operation rod 18. If the brake pedal is operated by force of more than the specified value, the on-off valve 57 opens and a passage 47 opens too, so that compressed air in an air pump 41 is introduced into the working pressure chamber 17, therefore differential pressure is produced in a power piston at a high velocity. When the brake pedal is yet largely operated, pressure in the working pressure chamber 17 goes beyond atmospheric pressure till it becomes the same pressure as that in a compressed air chamber 44, so the extent of yet larger differential pressure acts on the power piston 8.

Title: Method and device for compressing color reproducing area
Inventor: ARAI YOSHIFUMI
IPC: H04N1/60
Filed: 1998-11-24
Abstract: PROBLEM TO BE SOLVED: To practically compress a color reproducing area considering the space frequency characteristic of a visual system by a half arithmetic amount by replacing the updating expression of a compressed picture in an optimizing step with an approximate expression. SOLUTION: A picture from an inputting part 10 is given bi-directional color conversion by a conversion part 22 and its output is set as the inputted initial picture of the part 22. It is given bi-directional color conversion again by the part 22 to calculate the output of the conversion part. A filtering part 24 calculates a sensing difference amount ΔPD (r, o) through the use of the output of a part 24 and the part 10 according to an arithmetic expression. A color reproducing area extracting part 23 calculates a value T [M(r)] obtained by giving threshold value processing to the precision M(r) of bi-directional color conversion by using the picture before/after the bi-directional conversion of the part 22.  An optimizing processing 25 adjusts the input of the conversion part in the diving direction of an evaluation function PD to minimize the evaluation function PD defined by using the output of the part and the part 23. At this time, the diving direction is calculated by an approximate expression.
