In film-forming devices and plasma-processing devices, filmy matter adheres to the surfaces of the inner parts and it peels to cause dust and particles in the devices. In the devices, the dust and particles contaminate the objects for film formation thereon or the objects to be processed with plasma. For preventing the objects from being contaminated with them, the inner parts of the devices must be frequently exchanged every time when they have received any minor filmy matter thereon, and this lowers the productivity in the devices. When a modified glass part of which the surface is modified with spherical or bell-like island projections having a width and a height of from a few &#x3bc;m to a few hundreds &#x3bc;m is used in a film-forming device and in a plasma-processing device, then its ability to hold the filmy substance having adhered thereto is good and its resistance to plasma is also good. Therefore, the surface-modified part does not produce dust and particles and solves the problem of contamination of products. In addition, since the surface-modified part of the type has few pores and therefore releases few particles and little gas. Moreover, since the stress to be caused by the thermal expansion difference between the island projections and the substrate of the surface-modified part is small, the part does not peel even when heated, and it is favorable to vacuum devices.

Encoding apparatus and encoding method

A video encoder for reducing the deterioration of picture quality of a compress coded video signal by implementing a method for deciding the number of picture elements needed to properly encode an inputted video signal. The decision is calculated based on the difficulty of compressing the inputted video signal and the number of picture elements needed to accurately reproduce a compressed inputted video signal. The decision circuitry decides the number of picture elements needed for compression of the inputted video signal allowing the number of codes generated in the encoding process to be decreased and quantization accuracy improved. The main advantage is a reduction in deterioration of the video signal usually found when reproducing a compress coded video signal.

A solid-state imaging apparatus produces a sequentially-scanned video signal without using an expensive scanning converter. In the apparatus, an imaging device produces an image signal of each line based on the summation of signal charges of two adjacent lines. With the first mode being selected by the operation on the key panel, a timing generator is controlled to generate vertical shift pulses (field readout pattern) such that the two adjacent lines of the alternately-consecutive first and second fields are equal, causing the imaging device to produce an image signal for obtaining a sequentially-scanned video signal. An image signal processor implements the gamma modification process, etc. for the image signal to obtain the sequentially-scanned video signal. Sync signals VD and HD for sequential scanning or skip scanning generated by a sync signal generator are added to the video signal, and the output video signal is obtained.
