Abstract: A control apparatus for a rotary electric machine includes: operating unit for operating a DC-AC conversion circuit including a switching element so as to control a controlled variable of the rotary electric machine, the switching element selectively connects positive and negative terminals of a DC power source to respective terminals of the rotary electric machine and conduction period setting unit, in response to a rotational speed of the rotary electric machine, for setting a conduction period during which the respective terminals of the rotary electric machine, and the positive and negative terminals of the DC power source are allowed to be electrically connected therebetween via the switching element. The conduction period setting unit set the conduction period as a manipulated variable so as to reduce electromagnetic force distortion at a frequency corresponding to a resonant frequency of the rotary electric machine.

Abstract: According to an aspect, an electronic device includes: a first housing having a first display unit; a second housing having a second display unit; a detecting unit; and a control unit. The detecting unit detects a first form in which the first display unit is exposed to the outside and the second display unit is covered by the first housing and a second form in which the first and second display units are exposed to the outside. Then the detecting unit detects a change in the form of the electronic device from the first form to the second form, the control unit activates a function corresponding to a selected object among objects displayed on the first display unit, and displays a screen corresponding to the function on the second display unit.

Abstract: A linking device has a connecting member for connecting a first rotation member and a second rotation member. The connecting member is connected to the first rotation member at a first connecting point and to the second rotation member at a second connecting point. The connecting member includes a thermal deformation absorbing part between the first connecting point and the second connecting point, and is adapted to absorb a change of distance between the first connecting point and the second connecting point due to thermal deformation.

Abstract: A graphic display control device easily changes a display of a graph or graphic by operating an area where a graph or graphic is generally displayed. When a CPU detects trace execution inputting, the CPU displays a trace pointer on a graph, and simultaneously displays coordinates at which the trace pointer is positioned. Further, when the CPU detects an operation of a graph controller by an input pen, the CPU adds a predetermined value to an x-coordinate value of the trace pointer to perform tracing of the graph.

Abstract: A logarithmic graph plotting apparatus capable of easily setting and displaying x- and/or y-axes as logarithmic ones to thereby display a logarithmic graph. A graph range setting picture (View Window) is displayed by operating a “range” key. The x- and y-coordinate ranges are inputted and set on the graph range setting picture. Graph plot data (x1, y1) (x2, y2), (x3, y3), . . . , (xn, yn) corresponding to any particular graph function expression are calculated based upon the coordinate ranges to thereby plot and display a corresponding a graph in a coordinate system with the x- and y-coordinate axes. When logarithmic graph display check boxes ([ ]x-Log) and/or ([ ]y-Log) on the setting picture (View Window) are checked off, logarithmic scale lines corresponding to the set x- and y-coordinate ranges are set and plotted. In addition, each of the graph plot data (x1, y1) (x2, y2), (x3, y3), . . .

Abstract: A function f(x) input to an input device is differentiated to provide a derivative f′(x) and the derivative is further differentiated to provide a second derivative f″(x) in accordance with a predetermined program stored in a ROM or memory device. Data of an increase-decrease table for the function f(x) is produced based on positive and negative signs of values of the f′(x) and f″(x) in a given domain, and then stored in RAM. Then, the table is displayed on a display device based on the table data.

Abstract: A CPU produces a graph of a figure represented by a functional expression data input by a functional expression data input device, and displays it on a display unit. The CPU calculates and displays a volume of a body of rotation produced when the figure is rotated around a rotational axis in a range of the figure specified by a range specifying device or in a range determined based on the analysis of intersections of the figure and the rotational axis.

Abstract: A set diagram display control apparatus performs a set diagram display process. When the elements or number count of each of a plurality of sets is input to a set relation list, the element counts of all set relations are calculated in accordance with the elements or element counts of those sets. A display range of a set diagram is determined in accordance with the input or calculated element counts. The areas of circular diagrams which compose the set diagram are displaced in correspondence to their elements counts in the displayed range. And the displayed positions and radii of the circular diagrams are determined depending on the element count of the set diagram, in order to display the set diagram as composed of the circular diagrams.
