Title: Method for compensating variation of optical beam
Inventor: SAITO KENJI
IPC: G02B27/00
Filed: 1985-06-05
Abstract: PURPOSE:To compensate the shear of an optical beam and to fix the center of the intensity of irradiated beams always constantly by arranging an optical system for dividing an optical beam into two beams and irradiating the optical beams to an objective prescribed area so that the vector sum of variations of respective optical beams which may be caused by the variation of the time position of a light source and that of a radiation angle is always zero. CONSTITUTION:An optical beam 8a radiated from the light source 7 is divided into two optical beams 8c, 8d by a beam splitter 9, turned to two adjacent beams by a mirror 10 and a half mirror 11 and irradiated to an objective irradiating surface 12. If the optical beam 8a is varied to an optical beam 8a' shown by a broken line due to the variation of the light source, two divided optical beans 8c', 8d' are irradiated to the objective irradiating surface 12 as they are and the two beams 8c', 8d' are symmetrically varied to the position of an original optical beam 8e. Thereby, the two optical beams 8c', 8d' are varied always in the symmetrical directions to the irradiating point to be obtained at no variation of the light source, so that the shear of the optical beam due to the variation of the light source can be compensated.

Title: Fm modulator for picture signal
Inventor: MINAMI YUKIO
IPC: H04B10/07
Filed: 1980-09-05
Abstract: PURPOSE:To obtain always an FM signal of a constant frequency deviation, by increasing and reducing reversibly the peak value obtained by sampling the minimum level of the synchronizing part of a picture signal, and an amplitude of FM modulation signal. CONSTITUTION:A picture signal is reproduced through an FM modulator 3 and an FM demodulator 4. This picture signal has only the synchronizing part sampled in a sampling circuit 5 by the synchronizing pulse extracted by a synchronizing extracting circuit 8. The peak value of this sampling pulse changes in accordance with change of the DC level of the base part of the synchronizing part of the demodulation picture signal which changes due to the change of temperature. Consequently, the gain of a variable gain amplifier 2 is so changed that the amplitude of the signal to be inputted to the FM modulator 3 becomes small when the peak value of the pulse becomes large, thereby controlling the frequency deviation to a constant value. Reversely, when the peak value is small, the gain is made large.

IPC: B25J19/06
Filed: 1989-05-16
Abstract: PURPOSE:To save a wasteful calculation processing so as to attain a high speed operation processing by checking an interference by means of a linear function between lines. CONSTITUTION:The segment of the angle part of an arm in a robot, for example, is designated by an input part 2 as the segment which intends to check the interference. An interference check part 7 is operated through the track plan part 4 of the robot, and the interference of the segment and the outer line of a work is checked on a side view in the right angle direction of the work and the arm of a robot model. When it is judged that there is the interference, the interference by cross between the outer line of the work and the segment on a plan view is checked, for example. When it is judged that their is the interference, a coordinate on the side view of an interference candidate point in the plan view of the robot in the attitude is compared with the coordinate on work position data of the interference candidate point in the plan view of the work, and the presence or absence of the interference is judged. Thus, a processing is executed by the linear function and the high speed operation processing is attained since it is the check of the cross between the lines.
