Abstract: PURPOSE: To reproduce a good color image by controlling the operation of each electron gun and that of each deflecting device so that scanning of electron beams over a plurality of areas into which one screen part is divided, and switching of colors are performed using time division. CONSTITUTION: An electron beam 18 emitted from each electron gun 15 is deflected by horizontal and vertical magnetic fields produced by each deflecting yoke 16, to scan one screen part 13 while dividing it into a plurality of regions. The electron beams 18 emitted from the twelve electron guns 15 disposed within the necks 14 of twelve funnels 11 are deflected by the magnetic fields produced by the twelve deflecting yokes 16, so that the screen part 13 is scanned while being divided horizontally into four and vertically into three, a total of twelve regions. This division into the regions is controlled based on signals transmitted from a control part controlling the operation of each electron gun 15 and yoke 16. Thus a continuous color image that has no gaps and overlaps is displayed on the screen part 13.

Filed: 1988-06-27
Abstract: PURPOSE:To improve treatment efficiency by separating and recovering gaseous hydrogen from the decomposed gas which is generated from the inside of a methane fermentation tank and is discharged from a decomposed gas removing device under the discharge pressure of the decomposed gas by a hydrogen separating membrane device. CONSTITUTION:The decomposed gas generated by the anaerobic treatment of the waste water introduced in the methane fermentation 1 is sucked away by a blower 2 via a water draining tank 9 and a desulfurizing device 10. The gaseous hydrogen is separated from the decomposed gas by the discharge pressure of the decomposed gas in the hydrogen separating membrane device 4 and the separated gaseous hydrogen is stored in a storage tank 6. On the other hand, the decomposed gas from which the gaseous hydrogen is separated is supplied as fuel to a boiler 13 via a gas holder 8. The anaerobic treatment of the waste water is thus rapidly executed in spite of a high concn. and the treatment efficiency is improved. Since the decomposed gas removing device is commonly used as a driving device for the sepn. of the gaseous hydrogen, the waste water treatment and the gaseous hydrogen recovery are executed well with the small driving power.

Abstract: PURPOSE:To obtain a polyimide precursor vanish exhibiting little decrease of characteristics of a polyimide insulation layer even in the case of heat hardening directly on copper and capable of increasing long-time reliability of an electronic apparatus by compounding a specific polyimide precursor with a basic material, having a donor number, showing an electron donative property, within a specific range. CONSTITUTION:This polyimide precursor-based vanish is obtained by compounding a polyimide precursor having recurring units expressed by formula l (A is a tetravalent organic group; B is a divalent organic group; R is a 1-4C alkyl; n is an integer of 12-1150) with a basic material (e.g. trlethylamine) having an effect suppressing the reaction of a polyimide precursor-based vanish with copper atom. Here, the basic material has a donor number, showing an electron donative property, of 40-61 and is expressed by formula II (R' is H or a 1-3C alkyl; R'' is a monovalent or divalent aliphatic group; m is 1,2), etc. The copper atom content in the vanish layer is very low even in the case of direct hardening on copper. Accordingly, only a little lowering of insulation characteristics of the polyimide insulating layer is observed and long term reliability of electronic apparatuses having copper/polyimide insulation is enhanced.
