Abstract: A three-level power converter includes a direct current power supply unit including a filter capacitor connected between a high potential line and an intermediate potential line and a filter capacitor connected between the intermediate potential line and a low potential line, and a power conversion circuit that converts a three-level direct current voltage output from the high potential line, the intermediate potential line, and the low potential line into a three-phase alternating current voltage. A controller generates an imbalance signal representing an imbalance between a first capacitor voltage and a second capacitor voltage on the basis of values detected by voltage sensors, and generates a modulation signal for causing the power conversion circuit to perform a two-phase modulation operation on the basis of a superimposed signal obtained by superimposing the imbalance signal on a reference signal of the three-phase alternating current voltage.

Abstract: An assembling construction assembles a mountable member to a support member by holding a head portion of a clip on a mounting seat of the mountable member while securely fitting a leg portion in a mounting hole in the support member, the mounting seat has an instruction groove and guide grooves, the head portion of the clip has a first flange portion beam-like strip-shaped elastic pieces and which are brought into press contact with end portions of the guide grooves and stopper projections which are adapted to be brought into engagement with the end portions of the guide grooves when the clip is attempted to be shifted largely relative to the mounting seat.

Abstract: A sample analysis method is provided for analyzing a sample having a permeability to terahertz radiation and accurately measure the composition, physical properties, mass and dimensions of a very small sample or a minute amount of sample by irradiating the sample with terahertz radiation. In the method, a reflective member is provided adjoining a first principal surface of the sample, an entrance member is provided adjoining a second principal surface of the sample, terahertz radiation is delivered from outside of entrance member towards the sample, and the sample is analyzed using an interference wave generated from a first-surface reflected wave at the interface between the first principal surface of the sample and the reflective member and a second-surface reflected wave at the interface between the second principal surface of the sample and the entrance member.

Abstract: There is provided a stick-shaped body advancing holder or a combination of a holder and an eraser adapted to advance a stick-shaped body and to ensure chucking of the body or the eraser without enlargement of the entire configuration. A stick-shaped body advancing holder has an outer barrel, an inner barrel, and urging members, the urging members each being of a sawtooth shape and having bent portions. The urging members are arranged in a gap between flat faces of the outer barrel and flat faces of the inner barrel. On a knocking operation, the bent portions are deformed, thereby generating an urging force.

Abstract: An exposure method includes the steps of: detecting an alignment mark of a work W and an alignment mark of a mask M by an alignment camera 152; calculating a positional shift amount between the mask M and the work W and a distortion amount of the work W, based on a shift amount between both the alignment marks detected by the alignment camera 152; adjusting an alignment between the work W and the mask M, based on the calculated positional shift amount; and correcting a curvature of a plane mirror 166 for reflecting a light beam of exposure light from a light source 161, based on the calculated distortion amount, at the same timing as the alignment adjustment step or at a different timing from the alignment adjustment step.

Abstract: An inductor includes a flat substrate and a conductor in a spiral shape having a plurality of turns. The plane on which the conductor is formed is substantially in parallel with a principal surface of the substrate. The turns of the conductor are equally spaced from each other in a direction parallel to the plane on which the conductor is formed. An outer one of the turns of the conductor is wider and thinner than an inner one of the turns of the conductor. A level of at least one of a top and a bottom of the conductor differs from one turn to another in a cross section vertical to the plane on which the conductor is formed.
