Title: Silicon etching method
Inventor: HAYASHI HISAO
IPC: H01L29/786
Filed: 1984-09-14
Abstract: PURPOSE:To enable Si etching while controlling the film thickness stably and high-accurately by a method wherein the Si is etched with a thermal phosphoric acid having a liquid temperature above a specific value. CONSTITUTION:A polycrystalline Si layer 3 is annealed only in the neighborhood of the surface by irradiation with short-wavelength laser beams, thus forming grains (crystal grains) 5 of relatively large grain size in the neighborhood of the surface of this layer 3. Next, the lower region of the layer of grains 5 increased in grain size is turned amorphous by implanting e.g. Si<+> through the surface of the Si layer 3, resulting in the formation of an amorphous Si layer 6. Then, a polycrystalline Si layer 7 is formed by growing crystal grains of large size over the whole thickness of the Si layer 7 on heating. Finally, the surface of this polycrystalline Si layer 7 is etched with a thermal phosphoric acid at a temperature above 160 deg.C, e.g. approx. 170 deg.C, thereby reducing the film thickness and forming a thin polycrystalline Si layer 7.

Abstract: PURPOSE:To form a uniform coating on the whole inner surface of a face plat by jetting and blowing liquid material for forming the coating from plural up-directed supply nozzles disposed perpendicularly to the inner surface slmost close to tube axis, with the inner surface side of the face plate set downward.

Title: Vertical synchronization discriminating circuit
Inventor: KAWAHARA TSUKASA
IPC: H04N5/06
Filed: 1986-08-19
Abstract: PURPOSE:To obtain a stable vertical synchronization in case of a video signal input in which a frequency of a vertical synchronizing signal is non-normal, by providing a phase comparator for detecting a phase difference of an output signal from a voltage comparator and a frequency-divided output signal which is selected by a changeover switch, and outputting a reset signal to a frequency divider. CONSTITUTION:Phases of a signal from a voltage comparator 12, and a frequency-divided output signal fv2 are compared by a phase comparator 16, and as a result, if a vertical synchronizing signal has a normal frequency, a signal from the voltage comparator 12 also has a normal vertical frequency, and in this case, since the signal fv2 has a lower frequency than a normal vertical frequency, a reset signal outputted from the phase comparator 16 becomes a normal vertical frequency. That is to say, when the amplitude of an integral waveform signal of the vertical synchronizing signal is detected by a reference voltage V2 of a low potential, and the frequencydivided output signal of a low frequency, being the signal fv2 is outputted by a changeover switch 15, the phase comparator 16 outputs a reset signal by a frequency of the vertical synchronizing signal detected by a reference voltage V1 of a high potential.
