    摘要: This disclosure provides a valve which is controlled by a magnetic actuator. More specifically, the actuator is a polarized, magnetic actuator, that is, a magnetic actuator containing both a permanent magnet and an electromagnet. The actuator can be an inexpensive commercial relay having a pivoting armature that pushes a compliant diaphragm against a valve seat to close the valve. Preferably, the armature is configured as a “see-saw,” such that as the valve is opened, an opposing end of the see-saw also displaces the diaphragm. In this manner, fluid pressure in a valve chamber is relatively constant, and there are no significant pressures which prevent the valve from opening and closing. The preferred application of the valve is to actively drive printer ink supply, such that ink can be selectively drawn using the valve from a remote ink supply into a local ink reservoir, mounted near a print head. A sensor at the local reservoir is used to detect air or low pressure, and causes the valve to open and draw more ink into the local reservoir.

    摘要: There is an image processing apparatus to perform an image editing process such as to extract a part of an image or to synthesize a plurality of images. This apparatus comprises: an image information generator to generate image information; an area information generator to generate area information to extract a desired area of the image information; a coding circuit to compress and code the area information; a memory to store the area information which was compressed and coded by the coding circuit; a decoder to decode the area information in the memory; and an extracting circuit to extract the desired area of the image information on the basis of the area information which was decoded by the decoder. The coding circuit codes the area information on a unit basis of n.times.m pixels by use of a coding look-up table. The decoder also decodes the area information by use of a decoding look-up table. The image information is separated into lightness information and shape information on a unit basis of n.times.m pixels and stored. Thus, the capacity of the memory can be reduced.
