摘要:
An object of the present invention is to improve visual picture quality. A picture signal is divided into a plurality of macro blocks and coding is conducted in macro block units. The coding is conducted including quantization process by a quantization portion. A motion compensation portion outputs the quantity of motion, L, in macro block units. An average quantity of motion, L.sub.ave, of a reference picture stored in a frame memory is outputted from a division portion. A control portion compares the quantity of motion L with two reference values relative to the average quantity of motion L.sub.ave and makes a correction to lower the quantization step in the quantization portion for macro blocks whose quantity of motion L is between the reference values. Accordingly, picture quality is improved in part of picture where motion is small and deterioration of visual picture quality is noticeable. At the same time, since the correction is not applied to picture with such slow motion that deterioration of picture quality is small, redundancy of coded signal does not unnecessarily increase.

A first hydrogen-absorbing alloy electrode is obtained by applying a hydrogen-absorbing alloy powder on a collector or having a collector filled with a hydrogen-absorbing alloy powder and then sintering the hydrogen-absorbing alloy powder. The hydrogen-absorbing alloy powder is pre-pared by centrifugal spraying or gas atomizing and particles constituting the powder have a spherical shape, a nearly spherical shape, an egg-like shape or a mixed shape including the foregoing. The hydrogen-absorbing alloy electrode can readily be produced at low cost and have high packing density and good corrosion resistance, and can hence yield, when used for negative electrodes, metal hydride secondary batteries having excellent cycle characteristics. A second hydrogen-absorbing alloy electrode comprises a mixed powder containing a spherical-particle powder of a hydrogen-absorbing alloy and a powder as pulverized of the same alloy in a specific ratio. This electrode has high packing density and electronic conductivity, and can therefore gives batteries having excellent discharge characteristics on both high-rate discharge and low-rate discharge.

A data bus has a bit length of 2 words, and is divided into two bit groups, each of which corresponds to one word. Therefore, the data bus can simultaneously transfer data of two words. A register, a data operation part of a CPU, a RAM and a ROM is connected to the data bus. Even if there is generated data of two words to be transferred in these registers, the data operation part, the RAM and the ROM, the data bus can simultaneously transfer the data. In order to prevent conflict of data on the data bus, there are provided a bus driver, a multiplexer and a bus selector.

The present invention proposes the technique in which aluminum based alloy is used as a wiring material, and the number of process is sharply reduced in the technique of forming the aluminum based alloy wiring circuit, thereby making it possible to efficiently manufacture the element. The present invention is a method of forming the wiring circuit by the aluminum based alloy, wherein the development process of a resist layer and the etching process of an aluminum based alloy film are simultaneously performed with a developing solution for the aluminum based alloy film laminated with the resist layer. This aluminum based alloy is preferably 5 Å/sec to 40 Å/sec in etching rate by the developing solution.

There is disclosed a method of producing a lever including a pair of side plates, an interconnecting portion interconnecting one ends of the two side plates, a lock arm formed at the interconnecting portion so as to be engaged with a male connector, excessive displacement prevention piece portions formed on and projecting respectively from opposite side portions of the lock arm, and a pair of displacement limitation ribs which are formed respectively at opposite ends of the interconnecting portion, and project in a direction away from the side plates, and are disposed outwardly respectively of the excessive displacement prevention piece portions. The lever is injection molded in such a manner that those portions of the lock arm at which the excessive displacement prevention piece portions are formed, respectively, are disposed outwardly respectively of the displacement limitation ribs, and free ends of the side plates of the molded lever are moved toward each other so as to bend the interconnecting portion, thereby increasing a gap between the pair of displacement limitation ribs, and the portions having the respective excessive displacement prevention piece portions formed thereon are pushed to be disposed inwardly respectively of the displacement limitation ribs, so that each excessive displacement prevention piece portion is disposed between the corresponding displacement limitation rib and the interconnecting portion, and thereafter the bent interconnecting portion is restored into its initial shape, thereby canceling the expansion of the gap between the displacement limitation ribs.

A method of manufacturing a metal hydride alkaline storage cell includes a first step of preparing a negative electrode by applying a paste containing hydrogen absorbing alloy powder onto a substrate; and a second step of placing the negative electrode and a positive electrode into a cell can with disposing separator therebetween, and thereafter pouring an electrolyte into the cell can. Into the paste or the electrolyte, a catalytic metal compound that has a proportion of 0.1 to 2.5 wt. % based on the weight of the hydrogen-absorbing alloy powder and that is soluble in the electrolyte is added. Consequently, the catalytic action of the metal is fully utilized by this method that dots a catalytic metal or metal compound on the alloy surface, and thereby the inner pressure characteristic (high-rate charge characteristic) of a cell is improved.

Element processors (PE00 to PE33) included in a processor array (7) store pixel values of a search window, shifting them forward. Further, only hatched element processors (PE00, PE02, PE11, PE13, PE20, PE22, PE31, PE33) store pixel values of a template block, and compare them with the pixel values in the search to evaluate a similarity of pixel values. In other words, the pixel values of the template block are skipped and the pixel values which are left after skipping are compared. Therefore, it is possible to cut a hardware volume.
