Title: Control device for leg type moving robot
IPC: B25J5/00
Filed: 1992-03-31
Abstract: PURPOSE:To improve stability of control and responsiveness of a robot by a method wherein a control value of a leg part link is determined with precision approximately equal to that of a five-link model despite of three links in such a way as to determine the absolute angle of the leg part link based on an angle of a line for interconnecting a waist joint and a leg joint with a perpendicular direction. CONSTITUTION:A leg type moving robot 1 has right and left leg part links 2 which have six joints (shafts) 10R, 10L-20R, and 20L. A lowermost part is provided with flat legs (leg parts) 22R and 22L. Further, a drum body part (a base body) 24 is disposed to a topmost part and a control unit 26 is contained therein. The control unit 26 determines a solution by expressing an equation of motion by using a parameter containing an absolute angle with the perpendicular direction of the leg part link 2 and specifies a control valve according to the solution. In this case, the absolute angle of the leg part link 2 is determined based on the angle of a line for interconnecting a first joint (a waist joint) 12 and a third joint (a leg joint) 18 with a perpendicular direction.

Abstract: PURPOSE:To raise a vacuum degree at a baking time within a short time, by a method wherein Cl2-gas is introduced into a vacuum apparatus if necessary and the inner wall of the vacuum apparatus is irradiated with ultraviolet rays and the vacuum apparatus is heated simultaneously at this time or before and after this time. CONSTITUTION:In baking a vacuum apparatus, the inner wall of a vacuum chamber 1 is irradiated with ultraviolet rays 7 from the ultraviolet ray source 2 in the vacuum chamber 1 or the ultraviolet rays 7 transmitted through an ultraviolet ray pervious window 3 from the ultraviolet ray source 4 provided outside the vacuum chamber 1 simultaneously with the heating of the vacuum chamber 1 by a heater 6 or before or after heating. The molecules such as H2O, O2, N2 or H2 adsorbed by the inner wall are detached by the heating due to the heater 6 but, since the vibration of the adsorbed molecules is excited by the irradiation of ultraviolet rays, the detachment of the molecules is promoted. Further, by the introduction of Cl2-gas 8, the Cl2-gas is adsorbed by the inner wall and reacted with the molecules hard to evaporate and H2O to further facilitate the detachment of the molecules.
