Title: Manufacture of semiconductor device
Inventor: OKA SHINSUKE
IPC: H01L21/316
Filed: 1988-03-18
Abstract: PURPOSE:To suppress the sidwise growth by an anti-oxidation film and to largely improve a decrease in the integration due to a bird beak by allowing a thin semiconductor film to remain only in an opening formed by selectively etching the anti-oxidation film on an oxide film formed on the surface of a semiconductor substrate, and selectively oxidizing the remaining film. CONSTITUTION:A resist pattern 15 is formed on an Si3N4 film 13, the film 13 on a field region is removed by etching to form an opening 14, thereby exposing an SiO2 film 12. Then, the pattern 15 is removed, a polysilicon film 16 of a thin semiconductor film is formed on its surface. Further, after a resist 17 is formed on the film 16, the resist 17 and the film 16 are dry etched to flatten the surfaces, the film 16 remaining in the opening 14 of the film 13 is conducted by a hydrogen burning oxidizing method to form an element isolating oxide film 17. Accordingly, it can prevent its integration from decreasing due to the formation of a bird beak.

Title: Electric transmission system of picture
Inventor: OGATA YUKIHIKO
IPC: H04N1/417
Filed: 1984-04-03
Abstract: PURPOSE:To perform the conversion of picture density immediately before communication or during communication by converting the picture information in high density into run length codes to store them to a memory and converting the picture density immediately after the run length codes are read out of a memory. CONSTITUTION:The picture information read by a picture reading part 1 is converted into RL (run length) codes by a run length encoder 6 and stored to a picture memory 4. These RL codes are obtained by converting the white run (continuation of white) and the black run (continuation of black) into the numerical forms and are comparatively compressed compared with the actual picture information to be equal to the intermediate codes. In a transmission mode the RL codes read out of the memory 4 are supplied to a picture element density converter circuit 7. This picture element density conversion includes the conversion of the main scan direction which converts the length of the RL code and that of the secondary scan direction with thinned scan lines respectively.

Title: Refresh controller
Inventor: AIHARA NORIO
IPC: G11C11/401
Filed: 1982-04-19
Abstract: PURPOSE:To obtain a memory which has a necessary irreducible speed, by storing the frequency of the generation of a refresh request while CRY display operation is in process without performing refreshing operation, and then performing the refreshing operation in a blanking period as many times as it is not performed. CONSTITUTION:An oscillator 1 generates the memory refreshing request at specific intervals of time. The output of the oscillator 1 in a BUSY state wherein a CRT display device 8 accesses a memory 7 is cut off by an AND gate 2 to make the refreshing request ineffective, but a counter circuit 3 counts the signal; and the refreshing operation is performed through an AND gate 5 and an OR gate 6 after the access as many times as the counted frequency to reset the counter circuit 3. Consequently, the memory which has the necessary irreducible speed is obtained to improve the reliability.

Abstract: PURPOSE:To analyze ions of a chromic acid, a sulfuric acid, etc., simultaneously by a method wherein a chromium plating bath containing the ions of the chromic acid, the sulfuric acid and a fluosilicic acid is subjected to a gel permeation chromatograph(GPC) and analyzed. CONSTITUTION:In order to separate each component according to the size of a molecule, GPC elutes ions of a chromic acid, a sulfuric acid and a fluosilicic acid separately. For a GPC column 4, a column prepared by filling up a vinyl copolymer as a filler in a stainless steel column, for instance, is used. The particle size of the vinyl copolymer is preferably about 9mum and an exclusion limit molecular weight is suitably 3000 in terms of pullulan.
