Filed: 1987-10-26
Abstract: PURPOSE:To save electric power and accomplish a thin type color TV of high picture quality by controlling deflection of electron beam with a pulse current flowing in a superconductive magnet. CONSTITUTION:A negative DC voltage is impressed on a back face electrode 11 while a zero voltage on a grating electrode 13, and a negative electrode 12 is formed to generate a negative electric field. When negative pulse voltage with a time width corresponding to 80 horizontal rasters with different positions are impressed on this negative electrode 12 one after another, the potential at the electrode 13 becomes positive relatively, and areas around the negative electrode 12 will get positive electric field, and a band-shaped electron beam 10 corresponding to 80 horizontal rasters is radiated to the electrode 13. The beam 10 is divided by the electrode 13 and reaches a signal modulation electrode 14 and a vertical/horizontal deflecting coil 15 to be deflected vertically by feeding a coil 1a with vertically deflecting pulse current varying from H to H for projection onto a fluorescent stripe 17 of a face plate through the grating electrode 16. Thus color image is reproduced.

IPC: G06F11/22
Filed: 1989-10-17
Abstract: PURPOSE:To improve the alternation processing efficiency by suppressing the alternation processes for each main storage based on the instruction frequency of alternation processes of each main storage. CONSTITUTION:A fixed fault deciding part 3 decides whether the faults detected in the main storages 1(1) - 1(n) are fixed or not. The process propriety information generating parts 5(1) - 5(n) produce the process propriety information to show the propriety of the alternation processes based on the instruction frequency of alternation processes of each of storages 1(1) - 1(n). A process request output part 2 gives a process request to an alternation process instruction part 4 based on the produced process propriety information when a fixed fault is decided. The part 4 gives an alternation process instruction to store the corrected data to the alternation areas corresponding to the storages 1(1) - 1(n) where the faults are detected based on the process request of the part 2. In such a constitution, an alternation area is effectively used for a generated fault.

Abstract: PURPOSE:To enable the control to be easily applicable to a combination system, which apparatuses with ducts connected in different manners constitute, by a method wherein, when a ventilator alone is operated and in the case of an air-conditioning indoor apparatus through which the outdoor air taken in by the ventilator is passed and from which it is sent indoors, the indoor fan is operated, whereas where, in ventilating, the outdoor air taken in by a ventilator is sent indoors directly therefrom, the indoor fan is not operated. CONSTITUTION:In the case where the outdoor air taken in by a ventilator 21 is passed through an air-conditioning indoor apparatus 20 and then sent indoors therefrom, the ventilator 21 is controlled in parallel with the operation of the air-conditioning indoor apparatus 20 or, when the ventilator 21 alone is operated, an indoor fan 5a is put in operation; that is to say, the outdoor air drawn in through an inlet 3 is sent by an air-supply fan 5b of the ventilator 21 to the air-conditioning indoor apparatus 20 and then sent indoors therefrom by an indoor fan 5a. In the case where outdoor air is sent indoors directly from the outlet 2b of a ventilator 21 by an air-supply fan 5b and when the ventilator 21 alone is operated, an indoor fan 5a is not operated. This method enables a single operation-directing system to effect ventilation only or cooling or heating only or to effect both the ventilation and cooling or heating simultaneously.
