Abstract: PURPOSE: To effectively display a picture in a work station and a word processor by consecutively depressing a key for instructing the movement of the picture so that moving the picture on a CRT may be performed at high speed and stopping depression of the key so that moving the picture may be finely controlled. CONSTITUTION: When the change width of an address is initialized and the key for issuing requirement to move display data in a window is depressed, picture data is transferred to a frame memory for screen display from the data in a memory for storing the picture shifted by the change width of the specified address. In the case the key is not depressed after increasing the change width of the address, the change width of the address is initialized and becomes small. By keeping depression of the key showing the requirement to move the display data in the window, the moving speed of the picture in the window becomes high and the required picture is displayed in the window at high speed.  By stopping the depression of the key once, the change width of the address is initialized and becomes small, so that the moving speed of the screen becomes low and the displayed picture in the window is finely controlled.

Filed: 1987-09-18
Abstract: PURPOSE:To shorten the aging time by allowing a layer of oxidated alkali earth metal to contain previously prepared powder of barium scandate in uniformly dispersed condition. CONSTITUTION:5wt.% barium scandate is added to three-element carbonate powder of barium, calcium, and strontium, and thereto nitrocellulose lacker plus butyl acetate are added, followed by rolling, to prepare a suspension. This suspension is coated over the base metal by spray method, and heat is applied by a heater at the vacuum exhaust process to make pyrolysis from carbonate to oxides. This is heated to 900-1100 deg.C and subjected to activating process so as to obtain a cathode with stable electron emitting characteristic. Less than 0.1wt.% addition of barium scandate does not present favorable effect for practical application, while over 20wt.% addition gives a deteriorated initial characteristic that is not favorable in practical application.

IPC: H01S5/11
Filed: 1987-09-18
Abstract: PURPOSE:To make a laser beam with narrow spectral line width to be stably emitted, by adjusting the phase of the return laser beam in the boundary surface between a laser section and a waveguide section to a desired value by both the effects of diffraction gratings and the control of waveguide length. CONSTITUTION:A waveguide section comproses diffraction gratings 2B, 2C which are formed inside both the end surfaces of a waveguide 3 guiding the incident laser beam from a laser section, an index varying region N of the waveguide located between the diffraction gratings, an electrode 12 for controlling waveguide length which is disposed over the index varying region N in order to inject carriers by which the waveguide length is effectively controlled. According to this structure, the laser beam generated in the laser section is made to enter into the waveguide section, and the incident laser beam is then reflected by the end surfaces of the waveguide section to return the laser beam to the laser section. Therefore, when the spectral line width of the laser beam is contracted, the phase of the return laser beam in the boundary surface between the laser section and the waveguide section can be adjusted to the desired value owing to both the effects of the diffraction gratings and the control of the waveguide length.

The sampled reception echo ysm is applied to a phase calculating and inverting circuit 52, by which the phase is calculated and the code of the phase is inverted. The output thereof is applied as corrected phase information to a phase shifter 54. A delay circuit 53 delays the transmission time of the reception echoes y1-yn in accordance with the time required for the formation and output of the corrected phase information and applies said echoes to the phase shifter 54. The phase shifter 54 shifts the phases of the echoes y1-yn by as much as the phase-component indicated by the corrected phase information. The phase-transferred reception echoes are the output formed in the receiver as the reception echoes after the completion of tracking.
