Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To reduce a deteriorated image recovery time in a method using a cycle refresh. SOLUTION: An important are discrimination section 105 discriminates whether or not a macro block is included in an important area. The macro block included in the important area is stored in an important are memory 106 as an important area till the macro block is refreshed for a prescribed number of times or over. The macro block stored in the important area memory is used for an object of intra-refresh. Thus, even in the case that the image quality of the macro block included in the important area is deteriorated, the deterioration is recovered in a short time and deterioration of the image quality of a block in a preceding important area no longer remains.

Title: Straightener
Inventor: KATO RIKIO
IPC: G01F1/20
Filed: 1993-04-27
Abstract: PURPOSE:To provide a straightener for gas isolation valves in which the accuracy is enhanced in the measurement of flow rate by disposing the straightener for splitting a channel into a plurality of subchannels in the channel on the delivery side of the isolation valve thereby blocking the generation of swirl flow in the channel. CONSTITUTION:A straightener member 19 having four straighteners 19b for equally dividing a channel 21 into four around a central axis 18a is disposed in the flow path 21 within a nozzle section 7. When gas flows into an isolation valve 1, speed difference appears across the valve 1. But the channel 21 divided equally into four by the member 19 blocks the flow in the peripheral direction, i.e., a swirl flow, thus preventing generation of swirl flow positively. Since the complicated turbulent gas is straightened into a laminar flow and fed into a pool space in the downstream, measurement accuracy can be enhanced at a flow rate measuring section. Furthermore, pressure drop due to the straightener 19b is low and the member 19 integrally molded of resin can be produced at low cost and can be replaced easily.
