Title: Length measuring device
Inventor: NAKAJIMA HAJIME
IPC: G01B11/00
Filed: 1996-12-12
Abstract: PROBLEM TO BE SOLVED: To set interference period to a desired value and provide an absolute measuring signal without requiring reset to its original state, by using more than two parallel light fluxes which have different angles each other in the measurement of length for interference. SOLUTION: In position measurement of a measured object 105 which is driven by a liner table on a processing machine, coherent parallel beams A supplied from a light source 101 is branched into a beam B and a beam C by a wave combining/separating device 102. The beam B is reflected by a reflector 103 fixed on the object 105 and returns to the wave combining/separating device 102. The beam C is inclined by a specified angle 6 in relation to the beam B at a reflector 106, is reflected by a reflector 104 fixed on the object 105, returns to the wave combining/separating device 102, and combines with the beam B to be a beam D. The beam D interferes with the reflected beam B and C, and locations or others can be measured with any sensitivity corresponding to longer wave length than wave length determined by the set angle θ.  Two light waves whose frequencies are slightly different each other, and plural sets of light fluxes whose angles are variable can be also used.

Title: Digital vertical deflection circuit
Inventor: YATSUNO TADASHI
IPC: H04N3/23
Filed: 1987-12-28
Abstract: PURPOSE:To prevent production of distortion on a screen of a picture tube by counting a horizontal synchronizing signal such as an input video signal, changing linearly the magnitude of a magnetic field generated by a vertical deflection coil and varying the direction of the magnetic field from one to other direction. CONSTITUTION:A horizontal synchronizing signal and a vertical synchronizing signal of a video signal or the like are inputted to a counter circuit 1. When the count of the horizontal synchronizing signal is increased, since an H level output of the counter circuit 1 is increased in a binary way, the magnetic field generated in the vertical deflection coil is weakened and cancelled. Moreover, when the count is increased, the magnetic field is increased gradually in the opposite direction and reaches a maximum magnitude finally. Since the split winding coils 31-39 of the vertical deflection coil are subject to weighting such as one turn, two turns -256 turns, the magnetic field generated in the vertical deflection coil is varied linearly in a binary way is response to the number of horizontal synchronizing signals..
