  • Publication number: 20220325664
    Abstract: A rotating shaft of a rotary electric machine is supported by a rotary electric machine housing. For the rotary electric machine housing, compressed air flow passages are formed. In a gas turbine engine, an air bleed port is formed in a shroud case, and compressed air that is compressed by a compressor wheel flows into the air bleed port. The compressed air that has passed through the air bleed port flows through air bleed passages formed in an engine housing and the compressed air flow passages. Then, the compressed air flows into a rotary electric machine housing.

  • Publication number: 20220222187
    Abstract: In a controller (10), a CPU device #1 has a first authority to manage a peripheral device #1, and is a management device for the peripheral device #1. Each of a CPU device #2 and a CPU device #3 is a general device that has a second authority, which is lower than the first authority, for the peripheral device #1. Upon failing to read data from the peripheral device #1, the general device executes a diagnosis on the peripheral device #1 based on the second authority. The diagnosis by the general device causes the CPU device #1, which is the management device for the peripheral device #1, to receive an error notification indicating the error in the peripheral device #1. Upon receiving the error notification, the CPU device #1, which is the management device, handles the error in the peripheral device #1 based on the first authority.

  • Patent number: 11140276
    Abstract: An image processing apparatus performs operations. A mode is designated in repeat layout processing. A document area is detected by performing image analysis processing on a scanned image, and an inclination-corrected document image is acquired by performing extraction and inclination correction of a document image based on the detected document area. An initial repeat target area position is determined based on the acquired inclination-corrected document image and the designated mode, the inclination-corrected document image and a frame indicating the determined position are displayed, and a repeat target area designation screen is displayed to change a position of the frame indicating the repeat target area based on a user instruction. An output image is generated after the repeat layout processing by repeatedly laying out, in a designated sheet size, an image of the repeat target area determined based on the frame set on the repeat target area designation screen.

  • Patent number: 11126487
    Abstract: A clock value converter in a CPU replaces a value of a carry counter in a safety clock in the CPU to cause the carry counter to show dispersed values. The CPU transmits a frame including a value of a time stamp and a first error detecting code generated based on the value of the time stamp and the value of the carry counter to a CPU. A clock value converter in the CPU causes, as in the CPU, a carry counter in a safety clock in the CPU to show dispersed values. An error detector in the CPU determines whether a second error detecting code generated based on the value of the received time stamp and a value of the carry counter in the safety clock in the CPU satisfies a condition set for the first error detecting code.

  • Patent number: 11096592
    Abstract: A sensor module includes a light emitter that emits light beams including near-infrared light beams towards a subject; a light receiver that receives light beams having passed through the subject; and a controller that estimates biological information based on signals output from the light receiver. The light emitter includes a plurality of light emitting elements that emit near-infrared light beams having central wavelengths different from each other. The light emitter produces sets of light emissions by causing the plurality of light emitting elements to sequentially and intermittently emit the near-infrared light beams. In given two consecutive sets of light emissions produced by the light emitter, a second non-light-emission period of time T4 is longer than a first non-light-emission period of time T2. The controller estimates the biological information in a processing period of time T41 that is set in correspondence with the second non-light-emission period of time T4.

  • Patent number: 11081813
    Abstract: A connector is provided that is easy to assemble. A terminal fitting is arranged on a base of a housing, a conductor portion is inserted into a tubular portion of a conductor connection portion, and a lid portion is assembled on the base. Thus, an insertion portion is inserted between extension portions to that intersect each other, and a diameter of the tubular portion is reduced. The conductor portion is tightened by the tubular portion, and the conductor connection portion is connected to the conductor portion. Therefore, a dedicated machine is not required to connect the terminal fitting to an electric wire, and operation of connecting the terminal fitting to the electric wire and of accommodating the terminal fitting in the housing can be performed substantially simultaneously. Thus, the connector can be easily assembled.

  • Patent number: 11074441
    Abstract: Image analysis processing is performed on a scanned image to detect a document area and, based on the detected document area, a tilt-corrected document image is obtained by extraction and tilt correction of the document image. Further, an image output size of printing an image in a repeat target area specified based on the tilt-corrected document image is specified, magnification of the image in the repeat target area is changed to the output size, and the image is repeatedly laid out within a specified sheet size. Thus, in an apparatus that generates a repeat layout processed output image and controls print processing, an image output size which is the same as an image output size for the front side of a sheet is specified for the back side of the sheet in a case where the repeat layout processing is performed on both the sides of the sheet.
