Abstract: A conductive rod body is embedded in an insulative torch adapter into which a plasma torch is fitted so that a leading end protrudes from its outer circumferential surface. Further, a metal plate member electrically connected to a cable line to which a voltage for plasma ignition is applied is attached to a lower holder, and a conductive leaf spring member having a V-shaped cross section is attached to an upper holder. When the torch adapter is placed on the lower holder so that the protruding part of the rod body faces upward and the upper holder is closed to tighten a draw latch, the rod body and the metal plate member are electrically connected via the leaf spring member, and a high voltage for ignition can be applied to the plasma torch.

Abstract: A radiological image processing apparatus of this invention includes a separating device, an adjusting device and a removing device. Since a corrected image is generated using the radiological image taken through an object under examination, each image can be acquired by one radiographic operation without acquiring data for grid correction beforehand. The radiological image taken through the object is separated into a grid image and a non-grid image, and a corrected image is generated by adjusting intensity of the grid image on real space based on the non-grid image. Thus a high-precision correcting process is realized by one radiographic operation.

Abstract: A probe needle is successively moved to a plurality of measurement points set in a measurement region on a sample so as to measure a z-displacement amount. An excitation control unit feedback-controls a piezoelectric element so that a vibration amplitude of a cantilever is constant in accordance with the detection output by a displacement detection unit. Moreover, a vertical displacement control unit feedback-controls a vertical position scan unit so as to obtain a constant distance between the probe needle and the sample according to a frequency shift by a frequency detection unit. When changes of outputs of two feedback loops at a certain measurement point are both within a predetermined range, a main control unit issues an instruction to a horizontal position control unit to rapidly move to the next measurement point. As a result, it is possible to adaptively decide such a measurement time that both of the two feedback controls at respective measurement points are established.

Abstract: In a spectrophotometer, a position of a motor corresponding to a 254 nm bright line in the last check is read out from a memory section, and only a low-pressure mercury lamp is lighted up to scan a grating around the 254 nm line position in the last check, so that the 254 nm line position where a 254 nm line is ejected on a cell is detected. The low-pressure mercury lamp is turned off, and after only a D2 lamp is lighted up, the grating is scanned to detect an original position where an original or zero-order light is ejected on the cell and a 656 nm line position where a 656 nm line is ejected on the cell. Then, based on the 254 nm line position and the 656 nm line position which are actually measured, wavelength check is carried out.

Abstract: When a microchip is set on a tray and operation of an apparatus is begun, the microchip moves to feed position in order to be filled up with a buffer solution, where upon a sample is injected into this microchip. Thereafter the tray is located on a detecting position, so that a sample introduction voltage is applied between a sample reservoir and a sample waste reservoir for introducing the sample into a separation passage. Subsequently, the operation is switched to application of a separation voltage between a buffer reservoir and a drain reservoir, for beginning analysis. When the analysis has begun, a detector detects a migration pattern in the separation passage, so that a signal processing board data-processes the detected pattern.

Abstract: A hydraulic rotary actuator which comprises a harmonic drive and a hydraulic motor completely enclosed in the casing of the harmonic drive so that the rotation of the motor is taken out through an output shaft fixed to the drive at a reduced speed. In the casing of the harmonic drive there are provided an electromagnetic brake which acts on the motor, means for increasing the performance of the magnetic brake, means for magnetically shielding the supporting shaft of the hydraulic motor, and means for detecting the angular position of the motor and that of the output shaft relative to the supporting shaft of the motor.
