  • Patent number: 11948710
    Abstract: A non-oriented electrical steel sheet according to an embodiment of the present invention is a non-oriented electrical steel sheet including a base metal steel sheet and a composite coating film that is formed on surfaces of the base metal steel sheet and includes Zn-containing phosphate and an organic resin, wherein the non-oriented electrical steel sheet contains crystalline aluminum phosphate showing diffraction lines belonging to ICDD No. 01-074-3256 when the composite coating film is measured by a wide-angle X-ray diffraction method.

  • Patent number: 11936309
    Abstract: A permanent-magnet-synchronous electric motor control device includes: a reference voltage value calculation unit for calculating a reference voltage value; an output voltage value calculation unit for calculating an output voltage value on the basis of a voltage command; a current weakening command calculation unit for calculating a current weakening command on the basis of the reference voltage value and the output voltage value; a voltage command calculation unit for calculating the voltage command on the basis of the current weakening command; and a power converter for supplying power to a permanent-magnet-synchronous electric motor on the basis of the voltage command. The current weakening command calculation unit calculates the current weakening command in which a high-frequency component is amplified on the basis of the difference between the reference voltage value and the output voltage value.

  • Patent number: 10048953
    Abstract: A non-transitory computer-readable storage medium storing therein a compiler program for causing a computer to execute a procedure. The procedure includes copying a source program written in a parallel programming language to generate a plurality of optimization target programs corresponding to image numbers respectively; and repeatedly performing, for each of the optimization target programs, a first optimization that includes, substituting a function or a variable that indicates image number in the optimization target program with the image number, performing a constant propagation, deleting a conditional branch instruction having a condition under which a conditional statement is changed to a constant due to the constant propagation, and deleting a code that is not to be executed based on the conditional branch instruction.

  • Patent number: 8021718
    Abstract: A silicon resin is applied to the outer wall of the transition piece of a gas turbine subjected to the thermal barrier coating by caulking the cooling holes provided in the inner wall by a resin. Then, the transition piece is heated in an atmosphere furnace in order to burn or decompose the resin. A part of the silicon resin applied to the outer wall of the transition piece is decomposed or evaporated by the heating to be discharged to the atmosphere in the furnace, but a part of the silicon resin remains and protects the outer wall.

  • Publication number: 20100221441
    Abstract: A silicon resin (7) is applied to the outer wall (1b) of the transition piece (1) subjected to the thermal barrier coating by caulking the cooling holes (2a) provided in the inner wall (1a) by a resin (4). Then, the transition piece (1) is heated in an atmosphere furnace in order to burn or decompose the resin (4). A part of the silicon resin (7) applied to the outer wall (1b) of the transition piece (1) is decomposed or evaporated by the heating to be discharged to the atmosphere in the furnace, but a part of the silicon resin (7) remains and protects the outer wall (1b). Then, since the remaining silicon resin (7) protects the outer wall (1b), it is possible to reduce oxidization of the outer wall (1b) or an unevenness in color caused by the oxidization. Accordingly, it is possible to remarkably reduce the time required to improve an external appearance of the transition piece (1) after the ashing process for the transition piece (1).
