Title: Display device equipped with shared video memory
Inventor: SAKAGUCHI NORIYUKI
IPC: G06F15/16
Filed: 1987-02-20
Abstract: PURPOSE:To enable a CPU to use a video memory with no waiting time and to increase the processing speed of the CPU by adding a simple circuit so that the video memory can be separated from a display device as necessary. CONSTITUTION:When an address is received from a CPU 3, an address selector 10 sends the address data directly to a video memory 5 via an address bus selector 9 to realize a memory access via a data bus 8B and long as the whole or a part of the memory 5 is separated from a display 1. If the memory 5 is not separated from the display 1, the selector 10 sends the address data to a display circuit 2. The circuit 2 transmits a wait signal to keep the CPU 3 waiting only when the display 1 is kept in a memory access mode. In such a way, the memory 5 is utilized effectively and the processing speed is increased for the CPU 3.

Title: Negative electrode structure of magnetron and manufacture thereof
Inventor: NITSUTA KAZUHISA
IPC: H01J23/04
Filed: 1982-03-10
Abstract: PURPOSE:To prevent soldering from spreading over the outer surface of a negative electrode by a method wherein a spacer lying between an end hat and an end chip, being plate-shaped and having the diameter larger than the end chip and smaller than the end hat, the end chip, the negative electrode and a holder are soldered en bloc, further the end chip and the end hat are welded to be fixed. CONSTITUTION:A spacer 8 and solder 9 are placed on an end chip 3, the solder 9 is melted by high frequency heating so that an inside negative electrode holder 1, the end chip 3, the negative electrode 4 and the spacer 8 may be soldered en bloc. Thereby, as the spacer 8 is sufficiently thinner than the end chip and moreover its outer diameter is bigger than the end chip, temperature of its outer periphery is liable to rise thus accelerating the melting of solder 9 near said spacer and also functioning to check excessive generation of a flow of solder 9 to the side of the negative pole 4 due to a capillary phenomenon. That is to say, that solder melts from near the spacer so that it flows more between the spacer and the end chip as well as between the end chip and the holder and not so much into the junction surface between the negative electrode and the end chip.

Abstract: PURPOSE:To stabilize the concentration of phosphorus in finally treated water, in anaerobic and aerobic treatments for waste water disposal, by adding a calcium agent to precipitate calcium phosphate when the concentration of phosphorus in an anaerobic tank exceeds a predetermined value. CONSTITUTION:Raw water is supplied to a primary precipitation tank 1, and the resulting supernatant liquid is supplied together with returned sludge from a returning pipe 9 to a denitrification tank 2 and an anaerobic tank 3 to sequentially perform anaerobic treatment, aerated in an aerobic tank 4 and then separated into a liquid and solid matter in a final precipitation tank 5. In this disposal process, when the concentration of phosphorus exceeds a predetermined value with the increase of the amount of phosphorus discharged in the anaerobic tank 3, a calcium or alkali agent is added through a chemical feeder pipe 6 to make said concentration suited to the precipitation of calcium phosphate. Hence, excess phosphorus above the predetermined concentration is precipitated in the state of calcium phosphate, and the interior of the anaerobic tank 3 is maintained below the predetermined concentration. Hereon, said predetermined concentration of phosphorus is preferably about 15mg/l in general.

Filed: 1983-03-08
Abstract: PURPOSE:To enable to stably control a motor even if line voltage of the motor becomes excess due to external disorder by controller V/F in response to a load. CONSTITUTION:A current signal C from a current detector 8 is inputted to a sample-holding circuit 11. It is sampled by the rise of the output pulse (b) from an oscillator 6, and the sampled output (d) is produced. An adder 9 adds an analog voltage (a), the sampling output (d), a bias signal (e) in the shown polarity, and the added result is inputted to a pulse width setter 10. If a constant load is altered to a light load, the sampled output (d) accordingly varies, with the result that the pulse width of the signal (f) becomes small. In this manner, an AND gate 2 is operated to set the output voltage of the inverter 3 to a low value, V/F is altered, and an adequate voltage in response to the load is supplied to a motor M.

Filed: 1978-04-03
Abstract: PURPOSE:To prevent the deterioration of transistors caused by the reverse bias between the base and the emitter, by connecting diodes in the emitter side of a differential amplifier. CONSTITUTION:Diodes D1 and D2 are connected in the forward direction to current i, and a current-type switch is connected to the connection point of each diode from positive power source +V through resistance R5. At a normal input time, transistors Q3 and Q4 are so controlled that they may be turned on and off respectively. By this control, diodes D1 and D2 are turned on to flow a current in the forward direction, and the circuit is operated as a differential amplifier. When an excessive input is applied, the control input which truns off transistor Q3 and turns on Q4 is applied, and consequently, the amplifier is turned off as the result of the reverse bias of diodes, thereby protecting the circuit.

Abstract: PURPOSE: To make its possible to obtain a clear copy for an overhead projector or a second original, even in case a highly insulating substrate is used, by irradiating a photosensitive layer with light when a toner image is to be transferred.  
     CONSTITUTION: A negative electrostatic latent image, which is formed on a photosensitive layer 3 of a photosensitive material 1 for zerography, is developed with positively charged toners to form a toner image 4. A film 5 of polyethylene terephthalate laid on a conductive substrate 6 and having an intrinsic surface resistance higher than 10 13  ohms is charged negatively and overlaid on the layer 3. When the conductive substrate 1 of the material 1 and the substrate 6 are electrically connected, the toners are transferred electrostatically to the surface of the film 5. If the layer 3 is irradiated with its sensitive wavelength light, it is turned conductive so that the surface potential difference between the image and other portions is reduced. As a result, when the film 5 is peeled, the toners of the image portion are not shifted to the non-image portion.
