A motor control apparatus includes a sub-controller including a two-degree-of-freedom repetitive compensator and a shaping filter. The two-degree-of-freedom repetitive compensator includes a forward delay placed in a forward route of a loop and a feedback delay placed in a feedback route thereof and is configured so that a total delay time provided by the forward delay and the feedback delay is equal to the cycle of a target command or a disturbance. The shaping filter is configured so that the product of the pulse transfer function of the two-degree-of-freedom repetitive compensator and the complementary sensitivity function of a general-purpose control system has a low-pass characteristic.

A magnetic levitation system includes a levitation-actuator movable element which generates a levitation force applied to a control object; and a levitation-actuator stator which receives a reactive force while the control object is being operated, the levitation-actuator stator being attached to a fixed or movable structure. The levitation-actuator stator includes levitation-actuator stator units connectable to each other in a travelling direction. Each levitation-actuator stator unit includes a coil and an iron core for generating a levitation force between the levitation-actuator stator unit and the levitation-actuator movable element. A length of an end portion of each iron core is equal to or larger than a length of each coil between the ends of the coil so that the cores are continuously arranged without gaps therebetween when the levitation-actuator stator units are connected to each other in the travelling direction.

A robot is provided with: a base section; three motors set on the base section; a support so set that an axial centerline is perpendicular to a surface of the base section; pulleys; three wires into which nonlinear springs are incorporated; an output shaft connected to a load; a differential mechanism having a pinion gear connected to the output shaft and also having an affixation member disposed at the upper end of the support; a universal joint disposed at the ring of the differential mechanism; and a wire guide disposed at the affixation member of the differential mechanism. Two side gears of the differential mechanism and two motors are connected in one-to-one correspondence by means of two wires through the pulleys, and the remaining motor and the universal joint are connected by means of the remaining wire which is passed through the wire guide.

A duplexer includes: an insulation substrate having an upper surface on which a transmission filter and a reception filter are mounted, and a lower surface on which a foot pad layer electrically connected to the transmission filter and the reception filter is formed; a transmission pad provided on the upper surface and electrically connected to the transmission filter; a reception pad provided on the upper surface and electrically connected to the reception filter, a ring-shaped electrode provided on the upper surface and configured to surround the transmission pad and the reception pad; a ground foot pad included in the foot pad layer, and a via interconnection configured to electrically interconnect the ring-shaped electrode and the ground foot pad and to be provided in the ring-shaped electrode in a section along a shorter one of routes that connect the transmission pad and the reception pad to each other along the ring-shaped electrode.
摘要:
A substrate processing apparatus according to the present invention comprises a plurality of processing chambers, discharge systems each provided in conjunction with one of the processing chambers and a common discharge system connected with the discharge systems of at least two processing chambers among the discharge systems provided in conjunction with the individual processing chambers. The common discharge allows a switch-over between a scrubbing common discharge system that discharges discharge gas from each processing chamber after scrubbing the discharge gas at a scrubbing means and a non-scrubbing common discharge system that directly discharges the discharge gas from the discharge system of the processing chamber without scrubbing at the scrubbing means. In this substrate processing apparatus, switch-over control is executed to select either the scrubbing common discharge system of the non-scrubbing common discharge system in correspondence to the type of processing executed in the processing chamber.
