Abstract: A video image display apparatus of the flat tube and multi line cathode type of the present invention includes a phosphor screen, and a predetermined number (e.g. 15) of line cathodes for in-turn emitting a predetermined number of horizontal rows of electron beams. Each row has a second predetermined number (e.g. 320) of rod shaped electron beams for together producing one horizontal line of image on the phosphor screen. A vertical deflection means is provided for vertical deflection of the electron beams in turn at one vertically divided segment corresponding to one of the horizontal rows by means of a vertical deflection signal, e.g. a step wave having a saw-tooth wave envelope. The envelope is adjusted so as to be expanded or compressed or level changed, thereby eliminating any undesirable black horizontal band on the screen due to non-uniformity of electrode construction. A uniform raster is thereby obtainable.

Abstract: A flat type color display apparatus includes a phosphor screen and 15 horizontal line cathodes activated in turn from the top one to the bottom one. An electron beam control means and a beam deflection means are provided. Each horizontal line cathode emits a horizontal sheet-shaped electron beam which is vertically deflected in 16 steps, and is divided into 320 rod-shaped electron beams by 320 vertically oblong slits and individually controlled of its intensity by 320 beam-control electrodes. The rod-shaped electron beams are horizontally deflected each selectively impinging R, G and B vertical phosphor stripes in turn. In the operation circuit, R, G and B video signals are sampled and held in R, G and B parts of 320 sample-hold circuits, and stored at one time in 320 memories for respective colors, and time sharingly applied to the respective beam-control electrodes. A color video image is thereby displayed of 240 lines each having 320 picture elements.

Abstract: A flat type display apparatus includes an electron beam source for emitting a row of a large number of electron beams, and a phosphor screen having a phosphor layer which emits light in response to impingement by the electron beams. An electron beam convergence means is provided and an electrostatic deflection means for deflecting the electron beams prior to impingement on the phosphor screen. An electron beam controlling means has a number of electron beam controlling electrodes for individually controlling the current of the electron beams to control light emissions from the phosphor screen. A pulse width modulation circuit feeds electron control signals of a constant voltage and pulse-width modulated by video signal information to be displayed. Light emission control without changing converging conditions of electrostatic lenses is thus obtained so that a good linearity between the video signals and the electron beams is obtained.

Abstract: In the refreshing of the memory contents of the non-volatile memory device, a refreshing buffer memory is provided for temporarily storing a data signal of an address to be refreshed. Not only this data signal is stored in the refreshing buffer memory, but also the address of this data signal and the status of the refreshing processes, that is, up to which step of the refreshing routine the refreshing operation has proceeds, is stored in this refreshing buffer memory. Then, even when the power supply is shut off during the course of the refreshing action, at the next chance of the resumption of the power supply, the refreshing routine can correctly be started from the step at which the refreshing routine was previously terminated, thereby the refreshing operation can always be completed correctly.

Abstract: A pair of continuous slide fastener stringers are longitudinally fed by longitudinally reciprocable grip assemblies and driving rollers that is selectively actuatable. As the slide fastener stringers are advanced, one of the stringers is threaded through a slider held fixedly in its path of travel. The slide fastener stringers are cut off transversely across element-free gaps, and then the severed stringer pieces are moved forwardly until their leading end portions are positioned in a molding device, which molds a separable end stop on the leading end portions. The driving rollers are continuously driven to advance the slide fastener stringers until element-free gaps arrive at the cutter, whereupon the driving rollers are de-energized.

Abstract: A coated electrode having excellent electric conductivity and resistance against corrosion is obtained by electrodepositing lead dioxide on the surface of an alloy which consists of lead and silver.Prior to electrodepositing lead dioxide, the alloy is anodically oxidized beforehand in a solution of sulfate such that the surface of the alloy is oxidized. This enables the lead dioxide to be electrodeposited even in an acidic electrolyte.
