  • Publication number: 20240345057
    Abstract: A film sensor for detecting hydrogen in a metal material by being laminated on a surface of the metal material in a gas or in vacuum is formed of an organic polymer whose optical characteristic changes depending on a hydrogen concentration, and contains, if necessary, a dye whose optical characteristic changes depending on the hydrogen concentration. This film sensor can easily detect a concentration or a distribution of hydrogen present in the metal material, and additionally enables observation of change over time of the concentration or the distribution of hydrogen.

  • Patent number: 12111600
    Abstract: A powder conveying device includes a drop conveyance passage, an intersecting conveyance passage, a conveying screw, and a floating member. Powder entering from an inflow port drops in the drop conveyance passage. The intersecting conveyance passage communicates with a lower end of the drop conveyance passage and extends in an intersecting direction that intersects the drop conveyance passage. The conveying screw is disposed in the intersecting conveyance passage and rotates in a specified direction to convey the powder in the intersecting direction. The floating member is movably installed in the drop conveyance passage and floats in the drop conveyance passage to move by contact with the conveying screw. The inflow port and the floating member interfere with each other to prevent the floating member from coming out of the inflow port of the drop conveyance passage.

  • Patent number: 12085757
    Abstract: A device for fusion splicing, by an arc discharge, a pair or a plurality of pairs of optical fibers arranged so that end surfaces thereof face each other. An optical fiber arrangement portion positions the pair or the plurality of pairs of optical fibers between a pair of electrodes. A control portion controls a voltage applied to the pair of electrodes. The control portion generates a first discharge between the pair of electrodes, stops the first discharge between the pair of electrodes, and then generates an arc discharge between the pair of electrodes to fusion-splice the pair or the plurality of pairs of optical fibers to each other. A discharge time of the first discharge is 200 milliseconds or less. A time from stopping the first discharge to starting the arc discharge is 100 milliseconds or less.

  • Patent number: 12076277
    Abstract: A photocoagulation apparatus of some embodiment examples is configured to apply both treatment light for subthreshold coagulation and an OCT scan to a retina via a probe inserted in an eye. Upon receiving a user's instruction, the apparatus applies the treatment light to the retina, and applies an OCT scan to the retina at least after the treatment light application. The apparatus compares the first OCT image constructed from OCT data of the retina acquired prior to the treatment light application and the second OCT image constructed from OCT data of the retina acquired after the treatment light application, thereby acquiring change information that represents a tissue change in the retina caused by the treatment light. The apparatus displays a change image based on the change information together with a retinal image.

  • Publication number: 20240255890
    Abstract: An image forming apparatus includes a toner image bearer, a transfer device, a cleaner, a bias power source, and circuitry. The toner image bearer bears a toner image. The transfer device performs a transfer process The cleaner contacts the toner image bearer to remove transfer residual toner that is subject to the transfer process and remove untransferred toner that is not subject to the transfer process. The bias power source applies one of a first bias and a second bias different from the first bias to the cleaner. The circuitry controls the bias power source to output the first bias to the cleaner in response to a start of an image forming operation to remove the untransferred toner from the toner image bearer and control the bias power source to switch an output from the first bias to the second bias.

  • Publication number: 20210290437
    Abstract: A photocoagulation apparatus of some embodiment examples stores a first OCT image of a retina. The photocoagulation apparatus performs moving image photography of the retina to which aiming light is being applied, and repeatedly detects an aiming light image from a moving image. The photocoagulation apparatus moves a scan target area to include an aiming light application position. After treatment light application in response to user's instruction, the photocoagulation apparatus applies OCT scanning to the scan target area at a time of reception of the instruction, and constructs a second OCT image from acquired data. The photocoagulation apparatus compares the first and second OCT images to acquire change information representing a tissue change caused by the treatment light, and displays a change image based on the change information together with a retinal image.
