The performance of a power transducer is improved while efficiently using a power semiconductor also by managing the permissible duty factor of the power semiconductor in the regenerative braking circuit provided in the power transducer. The user is allowed to set, through an operation panel provided on the power transducer, the resistance value of the regenerative braking resistor for thermally consuming the rotational energy generated during motor deceleration. The power transducer performs the steps of: calculating the current which flows in the regenerative braking circuit from the resistance value setting; obtaining the generation loss of the power semiconductor in the regenerative braking circuit with the calculated current value; and determining the permissible duty factor of the power semiconductor from the obtained generation loss.

A three-dimensional (3D) structure data creation technique capable of readily creating 3D structure data is disclosed. This method is for producing data of a 3D structure which is made up of a plurality of elements. The method includes the steps of preparing first and second two-dimensional (2D) sectional images different in normal vector from each other, forming first and second unit graphics based on these 2D images, partitioning each unit graphic on a per-element basis, performing layout arrangement of two unit graphics in accordance with normal vectors, expanding these unit graphics for conversion to 3D objects, and allocating a selected element to a region in which elements of the unit graphics failing to coincide with each other, which region is included in and specified from those regions with intersection of respective partitioned parts of the unit graphics, thereby to create the 3D structure data required.

A select gate transistor has a select gate electrode composed of a first-level conductive layer and a second-level conductive layer. The first-level conductive layer has contact areas. The second-level conductive layer has its portions removed that are located above the contact areas. Two adjacent select gate electrodes that are adjacent to each other in the column direction are arranged such that the contact areas of one select gate electrode are not opposed to the contact areas of the other select gate electrode. One select gate electrode has its first- and second-level conductive layers removed in their portions that are opposed to the contact areas of the other select gate electrode.

When application software running on a PC is in the state of being terminated, a switch unit is turned OFF with the control of a CPU and individual motors, and in this state, a light source is not supplied with a motor/lamp-use power source. In this state, however, the CPU and individual I/Fs are supplied with a logic-use power source. Therefore, the switch unit is turned ON when the application software is started, and an initialization process for an individual electrically driven unit is no longer required.

An automatic analyzing apparatus has an analysis section including an immunity analysis unit and a biochemical componential analysis unit. A sample rack which has undergone the immunity componential analysis is horizontally fed by a rack feeding mechanism from a position confronting the inlet of a rack stationing section to a position near the outlet of the rack stationing section, so that the sample rack is directly moved to a return line, while skipping over the rack stationing section, so as to be efficiently returned to the analysis section and subjected to a subsequent biochemical analysis. A sample rack that needs reexamination by an identical analysis unit is also returned in the same efficient way.
