摘要： Disclosed herein is an ink set for use in ink-jet recording, which comprises at least 2 ink compositions the solid content concentrations of which are different by more than 2% by mass. The said at least 2 ink compositions each comprise an aqueous medium, a pigment and a dispersant for dispersing the pigment, and the dispersant is a block copolymer having an A segment that is a hydrophobic segment, a B segment that is an oxyethylene-structure-containing nonionic hydrophilic segment, and a C segment that is an ionic hydrophilic segment. The ratio of the number of unit structures of the A segment to the number of oxyethylene structures contained in the B segment (the number of unit structures of the A segment/the number of oxyethylene structures contained in the B segment) of the block copolymer contained in each of said at least 2 ink compositions is higher in the block copolymer contained in the ink composition having a relatively high solid content concentration than in the block copolymer contained in the ink composition having a relatively low solid content concentration.

摘要： In an articulation system for a robot according to the present invention, an eccentric rocking type planetary gear speed reducing mechanism is used, but a two-stage speed reducing structure is not employed. Output of an acceleration sensor (11) attached to an output shaft (7) of a speed reducer (10) is passed through a band pass filter (12) to obtain a vibration component. Based on the obtained vibration component and the rotational phase of the motor detected by a pulse coder (13), a vibration suppression correction torque corresponding to the rotational phase of the motor is determined. The vibration suppression correction torque is added to the torque command Tc to correct the torque command and causes the motor (1) to operate in accordance with the corrected torque command. The vibration suppression correction torque is determined by learning processing and is updated until the vibration component is sufficiently reduced. When the vibration component has been sufficiently reduced, this updating operation is stopped, the vibration suppression correction torque is fixed. Further, the torque command is corrected, and operation of the motor (1) is controlled in accordance with the corrected torque command.

摘要： A laser cutting method that offers a practically acceptable smooth cut surface without lowering the cutting speed. In this method, a laser beam machining device having a variable-curvature mirror assembly is used. The mirror assembly includes a mirror plate having a convex back side and a front reflecting surface, and a piezo-actuator for deforming the mirror plate to change the curvature of the reflecting surface. A laser beam is produced from the device so as to be reflected by the reflecting surface of the mirror plate and condensed at a focal point. The piezo-actuator is actuated to change the curvature of the reflecting surface, thereby oscillating the focal point along the optical axis of the laser beam at a frequency of between 150 Hz and 300 Hz and an amplitude of between ±0.5 mm and ±3 mm.

摘要： In a magneto-optical recording medium, a first magnetic layer for participating in reproduction of information is laminated on a substrate. A second magnetic layer for storing information is laminated on the first magnetic layer. A third magnetic layer having a Curie temperature lower than those of the first and second magnetic layers is disposed between the first magnetic layer and the second magnetic layer. A magnetization of a region of the first magnetic layer adjacent to a region of the third magnetic layer the temperature of which is above the Curie temperature of the third magnetic layer is aligned with the direction of magnetization of a region around the region of the first magnetic layer.

摘要： A variable-curvature mirror for a laser which makes it possible to obtain a high-accuracy spherical surface by uniformly deforming a reflecting mirror under a low load without stroke loss of an actuator. A top lid has a restricting surface for receiving the peripheral portion of the reflecting mirror to prevent translational movement of the reflecting mirror in the pressurizing direction. A gap is formed to permit pivotal motion of the peripheral portion of the reflecting mirror about the contact point with the top lid. Its thickness is radially changed so that its thickness reduces toward the peripheral portion. The reflecting mirror can thus be smoothly and uniformly deformed.

摘要： An ultrasonic delay line including an input transducer for producing a sound wave depending on an input voltage, a delay medium for transmitting the sound wave produced by the input transducer and an output transducer for receiving the sound wave transmitted in the delay medium has a shape such that sound waves transmitted in the delay medium are misdirected with respect to the output transducer by a predetermined amount. As a result, a substantial part of a main signal is input into the output transducer, whereas a substantial part of the sound waves having the third or higher harmonic component with respect to the main signal misses the output transducer due to the higher directivity of these higher frequency components in the delay medium.
