  • Publication number: 20250087969
    Abstract: A light-emitting device includes a waveguide-type light-emitting element formed on a cladding layer, a core formed on the cladding layer and constituting a port opposite to an output port of the light-emitting element, and a light absorption layer formed on the core in contact therewith. The core may be composed of a III-V compound semiconductor such as InP. The core is composed of a III-V compound semiconductor capable of guiding (transmitting) light (laser light) output from the light-emitting element. The light absorption layer is composed of a III-V compound semiconductor having a refractive index higher than that of the core, such as InGaAs. The III-V compound semiconductor having a higher refractive index has an absorption coefficient for light (light output from the light-emitting element) transmitted through the core.

  • Publication number: 20250018524
    Abstract: A method for polishing a diamond crystal includes preparing a diamond crystal having a main surface having a plane orientation of (100). Mechanical polishing is performed on the main surface using a polishing wheel such that: a tangent contacts a curve extending in a rotation direction of the wheel and contacting a contact position between the diamond crystal and the wheel that is rotating; and a tangent direction of the tangent at the contact position is within a range of ±10 degrees relative to a <110> direction of the diamond crystal, thereby causing an affected region to appear such that the affected region is parallel to a direction of a plane orientation (111) of the diamond crystal and penetrates the diamond crystal onto the main surface. Chemical mechanical polishing is performed on the main surface to remove the affected region, thereby removing the affected region from the main surface.

  • Patent number: 11459197
    Abstract: The document feeder includes a lift plate, a pickup roller, a lift motor, a retard roller, and a control unit. In a manual feed mode, the control unit rotates the retard roller to feed a document in a document conveyance direction. Further, the control unit causes the lift motor to start lowering the lift plate while the pickup roller is feeding a document after starting to rotate the pickup roller. When there is a document set on the lift plate at the time when the pickup roller stops, the control unit automatically resumes the feeding in the manual feed mode.

  • Patent number: 11459196
    Abstract: A controller starts sheet feeding at a primary sheet feeding speed, then momentarily stops a sheet feeding rotary member, and thereafter starts secondary sheet feeding. When the secondary sheet feeding speed equals a first speed, the controller momentarily stops the sheet feeding rotary member such that the leading end of a document sheet stops at a first stop position. When the secondary sheet feeding speed equals a second speed, the controller momentarily stops the sheet feeding rotary member such that the leading end of a document sheet stops at a second stop position. The second stop position is located downstream of the first stop position in the document conveying direction.

  • Patent number: 11368594
    Abstract: Conveyance modes include a registration mode accompanied with skew correction and a registrationless mode unaccompanied with skew correction. When a jam occurs, the controller interrupts a job, and invokes blank-feed processing starting from a state with all sheets re-set. On invoking blank-feed processing, the controller checks the conveyance mode and recognizes the number of jams. If the conveyance mode is the registration mode and in addition the number of jams has not reached a threshold number of jams, the controller invokes blank-feed processing in the registrationless mode.

  • Patent number: 11324435
    Abstract: A heartbeat detection device including a time difference value calculation unit to calculate a time difference value from a sampling data string of an electrocardiographic waveform of a living body, an index value calculation unit to calculate an index value for heartbeat detection based on the time difference value, a threshold setting unit to determine whether a peak of the index value exceeding a threshold can be detected, to calculate, a threshold candidate based on an average value of the predetermined number of the most recent peaks among these peaks. A threshold candidate is set as a new threshold when the threshold candidate has a value equal to or less than a threshold limit value. A heartbeat time determination unit sets the sampling time of the peak as the heartbeat time when the peak of the index value exceeding the threshold is detected.

  • Patent number: 11128762
    Abstract: An information processing device includes an acquiring section, an encoding section, and a learning section. The acquiring section acquires log information indicating an operational condition of an electronic device.

  • Patent number: 11090007
    Abstract: A residual anaerobic work capacity calculating method includes a step (S1) of obtaining a heart rate, and a step (S2, S3) of calculating a residual anaerobic work capacity based on the obtained heart rate and a relationship between the residual anaerobic work capacity and the heart rate. This method need only measure the heart rate when calculating the residual anaerobic work capacity, and obviates the need to measure power by using an expensive power meter.
