Title: Digital filter
Inventor: KOYAMA HITOSHI
IPC: H03H21/00
Filed: 1983-07-27
Abstract: PURPOSE:To stabilize an output of the entire filter by changing content of a unit delay element from the outside of the filter at the revision of a multiplication coefficient of the filter so as to stabilize the internal arithmetic operation of the filter. CONSTITUTION:The filter consists of an operation section 1 and a control section 2. The result of operation of multipliers 4, 5 is added to an input value by an adder 3 of the operation section 1 and the result is inputted to the unit delay element 6 and an output detector 11. The value delayed by a unit value at the element 6 is inputted to the multiplier 4 and a unit delay element 7, where the value is delayed by the unit and the result is inputted to the multiplier 5. The values delayed respectively by the element 6, 7 are multiplied with a multiplication coefficient decided by a multiplier controller 9 at the multipliers 4, 5, and the result is inputted to the adder 3. A main controller 8 commands the change in the multiplication coefficient to the controller 9 according to an external control signal 12. The controller 9 changes the multiplication coefficient for the multiliers 4, 5 with the command. A detector 11 gives a command of change of the content of the unit delay elements 6, 7 to a controller 10 when an absolute value of the output value is within a prescribed range and the controller 10 executes the command. Thus, the filter is driven with a new multiplication coefficient in this way when the output value is within a prescribed range so as to stabilize the output.

Filed: 1985-06-26
Abstract: PURPOSE:To attain the high speed execution of graphic erasing by selecting an optimum method out of two erasing methods to erase an optional graphic out of plural ones sharing the same picture element and displaying only a graphic necessary for rewriting again. CONSTITUTION:When a graphic forming command and a scale value are inputted from a keyboard 21, a CPU 22 converts the input data into a signal coincident with a fixed rule and stores the converted signal in a storage device 23. The data are displayed on a display 26 and the CPU 22 drives the data into partial areas having equal intervals of graphic areas and regulates partial area numbers. Then, each graphic position information is found out and the optimum method out of two erasing methods, 'erase a graphic to be erased' and 'erase a partial picture', is selected on the basis of the number of graphics to be erased to erase the graphics. The OR of all the erased graphic position information is found out as display information and compared with each graphic position information and a graphic to be rewritten is discriminated and displayed. Consequently, graphic erasing can be executed at a high speed.

Abstract: PROBLEM TO BE SOLVED: To achieve a highly accurate measurement of the displacement of a test piece as caused by a creep deformation or a plastic deformation of the test piece during a test by forming on a stress load member a light transmitting hole for detecting the displacement thereof during the testing period. SOLUTION: Grooves 13 and 14 are formed in side walls of recess parts of an upper holding member 4 and a lower holding member 10 and light transmitting holes 15 and 16 are formed so that lights incident from the outside of the holding members 4 and 10 pass diametrically through the recess parts by way of the grooves 13 and 14. Then, light such as laser light is irradiated to the light transmitting holes 15 and 16. The irradiated lights are partially shielded by the holding member 10 and a support member 8 or the holding member 4 and a stress load member 2 to reach the side opposite to a jig. The positions of the passed lights are detected by photosensors respectively provided on the sides opposite to the light incident sides of the light transmitting holes 15 and 16 to determine a distance between the detected positions.  When a test piece deflects, the positions of the light passing through the light transmitting hole 15 deviate downward to reduce the distance, thus enabling detecting of the resulting changes in variation as the degree of deflection of the test piece.

The light L emitted from the liquid crystal panel 10 is made incident on an exit-side polarizing filter 32 through a color filter 20 and an optical fiber plate 40. Since an exit end face 411 of the optical fiber plate 40 is subjected to frosted glass surface treatment, the nondirectional light L is emitted through the exit-side polarizing filter 32. Consequently, the light L emitted from this liquid crystal display device, namely, a picture has not directivity.
