  • Patent number: 10381959
    Abstract: A motor control device includes: an inverter circuit including a semiconductor switching element for drive which drives a motor; a cut-off circuit including a semiconductor switching element for cut-off which cuts off an electric connection between the motor and the inverter circuit; a failure detection unit; a rotation number detection unit; and a control unit. In a case where the failure detection unit detects a failure of the semiconductor switching element for drive, the control unit turns off the semiconductor switching element for drive, and in a case where the number of rotations of the motor which is detected by the rotation number detection unit is less than a predetermined first threshold, the control unit further turns off the semiconductor switching element for cut-off.

  • Publication number: 20190038066
    Abstract: An extracting method of extracting a beverage liquid from an extraction target includes a pressure reduction step of switching an interior of an extraction container in which the extraction target and a liquid are stored from a first air pressure to a second air pressure lower than the first air pressure, and an extraction step of extracting the beverage liquid from the extraction target. The first air pressure is an air pressure at which the liquid at a predetermined temperature does not boil, and the second air pressure is an air pressure at which the liquid that does not boil at the first air pressure boils. The switching from the first air pressure to the second air pressure is done by releasing the air pressure in the extraction container.

  • Patent number: 7795137
    Abstract: When a tungsten film (43) is embedded inside of a conductive groove (4A) formed in a wafer (W2) and a silicon oxide film (36) thereon and having a high aspect ratio, film formation and etch back of the tungsten film (43) are successively performed in a chamber of the same apparatus, therefore, a film thickness of the tungsten film (43) deposited in one film formation step is made to be thin. Whereby problems, such as exfoliation of the tungsten film (43), generation of micro-cracks, and occurrence of warpage and cracks of the wafer (W2), are avoided.

  • Patent number: 7777346
    Abstract: In manufacturing a semiconductor integrated circuit device, an interconnect trench and a contact hole are formed in an interlayer insulating film formed over a first-level interconnect on a semiconductor substrate, a barrier film is formed inside of the trench and contact hole so that its film thickness increases from the center of the bottom of the hole toward the sidewalls all around the bottom of the contact hole, a copper film is formed over the barrier film, and a second-level interconnect and a connector portion (plug) are formed by polishing by CMP. In this way, the geometrically shortest pathway of an electrical current flowing from the second-level interconnect toward the first-level interconnect through a connector portion (plug) does not coincide with a thin barrier film portion which has the lowest electrical resistance, so that the current pathway can be dispersed and a concentration of electrons does not occur readily.

The results are added by an adder, thereby providing a correlation eliminating filter for extracting a signal component from the input signal X of one channel having a high correlation with the input signal Y of the other channel. There is provided a coefficient updating processing device 5 for successively changing the feature of the correlation eliminating filter according to an error signal e obtained from the output signal RES and the input signal Y from the other channel, and the input signal X of one channel. A surround signal is obtained from a difference between the output RES from the correlation eliminating filter and the input signal Y of the other channel.
