Abstract: A motor control device according to the present disclosure includes: a motor drive circuit that outputs a drive current to a motor; a drive current detector; a main control unit, and an auxiliary control unit, wherein the main control unit has a first control signal generator that generates a first control signal based on a detected current signal; a first drive signal generator that generates a drive signal based on the first control signal, and a first switcher that switches to an output state of the motor drive circuit of the drive signal, and the auxiliary control unit has a second control signal generator that generates a second control signal; a second drive signal generator that generates the drive signal based on the second control signal, and a second switcher that switches to an output state of the motor drive circuit of the drive signal.

Abstract: An aluminum alloy wire with a composition that contains at least one metallic element selected from the group consisting of Fe, Cr, Ni, Co, Ti, Sc, Zr, Nb, Hf, and Ta in the total amount of more than 1.4 atomic percent and 5.1 atomic percent or less and a remainder of Al and incidental impurities, wherein the aluminum alloy wire has a tensile strength of 250 MPa or more and an electrical conductivity of 50% IACS or more.

Abstract: Disclosed is a method of executing test programs for a semiconductor testing system performing function tests on a semiconductor device through the execution of the test programs by means of an operating system. When a statement of a test program for designating a predetermined set value is executed, the set value is stored in a data area. Then, when a statement on the execution of a function test is executed, the above set value is read to set a corresponding circuit, after which the function tests are carried out.
