Abstract: A method for manufacturing a light-emitting element includes providing the light-emitting element that includes a light-emitting layer with an emission wavelength of not more than 306 nm and a p-type layer including AlGaInN including Mg as an acceptor, and removing hydrogen in the p-type layer from the light-emitting element by irradiating the light-emitting element with ultraviolet light at a wavelength of not more than 306 nm from outside and treating the light-emitting element with heat in a state in which a reverse voltage, or a forward voltage lower than a threshold voltage of the light-emitting element, or no voltage is applied to the light-emitting element. The removing of hydrogen in the p-type layer from the light-emitting element is performed in a N2 atmosphere at not less than 650° C. or in a N2+O2 atmosphere at not less than 500° C.

Abstract: Data samples derived from raw physiological data captured by sensors of a wearable medical device monitoring a patient's heart, such as a first ECG channel data sample, a second ECG channel data sample, and/or a cardio-vibrational data sample, are applied to a multi-tier machine learning engine to determine a cardiac condition measure traditionally calculated based upon information typically derived in a laboratory or clinical setting. A first tier of the multi-tier machine learning engine may analyze the physiological data sample(s) using first machine learning classifier(s) to obtain a first result. The first result may then be applied to second machine learning classifier(s) of a second tier of the machine learning engine, along with physiological metrics and/or patient clinical information, to determine the cardiac condition measure.

Abstract: An image forming apparatus includes an image forming device, a transport route, a purge transport route, an image forming transport route, a transport roller, and a blowing machine. The image forming device forms an image on a sheet. The transport route extends to a predetermined position. The purge transport route extends to a downstream side in a sheet transport direction, from the predetermined position. The image forming transport route is branched from the purge transport route at the predetermined position, and extends toward the image forming device. The transport roller transports the sheet along the transport route, and along one of the purge transport route and the image forming transport route. The blowing machine delivers the sheet to one of the purge transport route and the image forming transport route, by blowing air to the sheet being transported along the transport route.

Abstract: A suction fan of a sheet feeder sucks in air through a sheet feeding belt to generate flotation air. The suction fan uses the flotation air to attract set sheets by suction. A belt motor rotates a sheet feeding belt and feeds out a sheet of the set sheets. An interval measurer measures a sheet-to-sheet interval when the suction fan is attracting the sheet by suction. Based on an output of the interval measurer, a controller recognizes the sheet-to-sheet interval. Based on the recognized sheet-to-sheet interval, the controller adjusts a flow rate of the flotation air.

Abstract: An image forming apparatus includes an image reading unit, a fixing unit, a time setting unit, and a control unit. The image reading unit moves a running body having an onboard optical system. The fixing unit heats toner transferred onto the print medium and applies pressure on the heated toner with respect to the print medium to fix the toner. The time setting unit sets an estimated time when use of the image forming apparatus starts. The control unit controls the image reading unit, the fixing unit, and the time setting unit. The control unit, prior to the set estimated start-of-use time by a predetermined period set in advance, activates the image reading unit to detect whether condensation has occurred in the optical system, heats the fixing unit in response to a detection of occurrence of condensation, and stops the heating before the estimated start-of-use time.

Abstract: There is provided a synthetic resin welded body and a method of manufacturing the same, in which it is possible to make only a portion of an absorption-side synthetic resin part to be welded likely to melt in laser welding. The synthetic resin welded body includes: a laser light absorbing oil passage forming member (absorption-side synthetic resin part); and a laser light transmissive baffle plate (transmission-side synthetic resin part) which is laid over the oil passage forming member and laser-welded in this state. The baffle plate is formed so that a welded area which is laser-welded to the oil passage forming member is higher in laser transmittance than a non-welded area which is the other area.

Abstract: A method of manufacturing the synthetic resin welded body includes the steps of: preparing an oil passage forming member including a welding portion having a top portion serving as a welding face; preparing a baffle plate having a welded face; disposing the oil passage forming member and the baffle plate so that the welding face comes in contact with the welded face; and radiating laser light to the welding portion to weld the welding face and the welded face. A recess is formed in the baffle plate so that a groove portion is formed along an outer peripheral face of the welding portion when the oil passage forming member and the baffle plate are disposed so that the welding face comes in contact with the welded face.

Abstract: An image reading device includes contact glass, a frame, a light emitting section, a sensor, and a control section. An original document is placed on the contact glass. The flame surrounds the periphery of the contact glass. The light emitting section emits light toward the contact glass and the frame. The sensor detects a first received light amount resulting from first reflected light that has passed through the contact glass and a second received light amount resulting from second reflected light that has been reflected off the frame. The control section compares temporal variation of the first received light amount with temporal variation of the second received light amount. The control section determines whether or not the temporal variation of the first received light amount indicates presence of the original document on the contact glass using the temporal variation of the second received light amount as a reference.

Abstract: An image reading device, at a starting time point, starts one mode gain setting processing, which is processing of obtaining a gain set value of a shared amplifier in one of a color mode and a monochrome mode. After the one mode gain setting processing is completed, the image reading device performs an other mode gain setting processing, which is processing of obtaining a gain set value of the shared amplifier in the other mode. In a case where an instruction to perform a reading job in the one mode is received while the other mode gain setting processing is being performed, the image reading device discontinues the other mode gain setting processing and performs the reading job in the one mode.
