Title: Method for adjusting geometric distortion and convergence
Inventor: TOMOHARA MASAYASU
IPC: G09G1/00
Filed: 1995-03-07
Abstract: PURPOSE: To easily and quickly adjust geometric distortion and convergence by displaying a video signal by slash lines and adjusting the change quantity of a parabolic wave so that a projected image is straightened. CONSTITUTION: A video signal diagonally passing straight lines L15, L16 from an intersection P1 to an intersection P33 and from an intersection P31 to an intersection P3 in an area L1 to L4 surrounded by horizontal and vertical synchronizing signals is displayed on a projection picture display device having a circuit capable of adjusting the linearity of the horizontal direction. The deflection angle of the horizontal direction is adjusted at a fixed angle by adjusting the change quantity of a parabolic wave so that a projected image is straightened. Since the correction values of plural correction waves can be respectively recognized, geometric distortion and convergence can be easily and quickly adjusted.

Title: Binary coding circuit
Inventor: KITAGAWA TAKASHI
IPC: H04N1/403
Filed: 1982-03-24
Abstract: PURPOSE:To perform correct binary coding by detecting the maximum and minimum points of an analog picture signal, varying the white and black peak-held value of the analog picture signal to the current maximum and minimum voltages forcibly, and coding the analog picture signal into a binary signal on the basis of the mean value of both held values as a threshold value. CONSTITUTION:The analog picture signal is inputted from a terminal 60 and capacitors 70 and 71 are charged to a positive or negative peak value. When the signal does not have the peak value, the capacitors are discharged with time constant determined by resistances 73 and 71. When a peak phase detecting circuit 61 detects the maximum point, a transistor (TR) 66 is turned on to vary the value of the capacitor 70 to the current maximum value of the analog picture signal focibly. For the minimum point, a TR67 functions similarly. Consequently, the potentials of the capacitors 70 and 71 approximate a maximum and a minimum envelope potential and the plus input side of a comparator 77 approximates the mean value of the picture signal, thus performing the correct binary coding operation.

Title: Equipment for regulation of origin
Inventor: AICHI KAZUO
IPC: G01B7/00
Filed: 1982-03-24
Abstract: PURPOSE:To enable the high accuracy regulation of the error range settled with the resolution of an encoder, by pure-binary-coding the signal from a rotary encoder of absolute type and by generating the complement value. CONSTITUTION:The code of electric signal of rotary encoder 2 of absolute type is converted to an easily calculable pure binary number with a conversion circuit 61. The complement value generation circuit 62 generates 2 complement values of the output number of the circuit 61 and outputs then to an adder 63 when the machine is at an origin. The output signal of adder 63 is zero when the machine is at the origin and increases at the same rate with the increase of input from the encoder 2. As a result, the mechanical origin coincides with the zero point of electric signal. Furthermore, the easy coincidence of them with the high accuracy of the error range of the minimum angle settled with the resolution of encoder can be provided without the necessity of mechanically difficult regulation.
