  • Patent number: 10916460
    Abstract: A wafer producing apparatus for producing an SiC wafer from a single-crystal SiC ingot includes an ingot grinding unit, a laser applying unit that applies a pulsed laser beam having a wavelength that is transmittable through the single-crystal SiC ingot while positioning a focal point of the pulsed laser beam in the single-crystal SiC ingot at a depth corresponding to the thickness of the SiC wafer to be produced from an upper surface of the single-crystal SiC ingot, thereby forming a peel-off layer in the single-crystal SiC ingot, a wafer peeling unit that peels the SiC wafer off the peel-off layer in the single-crystal SiC ingot, and a delivery unit assembly that delivers the single-crystal SiC ingot between the ingot grinding unit, the laser applying unit, and the wafer peeling unit.

  • Patent number: 9625869
    Abstract: An image forming apparatus having: an image supporting member; an electrostatic latent image forming section; and a developing device. In the developing device, a supply member receives toner, polish and antifriction at a supply part. The supply member supplies the toner, the polish and the antifriction to a developing roller while conveying the toner, the polish and the antifriction in a predetermined direction along a rotation axis of the image supporting member. A developing roller develops an electrostatic latent image by supplying the toner, the polish and the antifriction to the image supporting member. A toner patch is formed on the image supporting member, in a facing area capable of facing the developing roller, such that the amount of toner adhering to the image supporting member decreases with increasing distance in the predetermined direction from the supply part. A cleaner removes the toner patch from the image supporting member.

  • Publication number: 20150177143
    Abstract: A particle detection device detects a biological particle. The particle detection device includes a collection sheet, a collection unit, a heating unit, a fluorescence detection unit, and a movement mechanism. The collection unit introduces an airborne particle into the device so that the airborne particle is collected on the collection sheet. The heating unit heats the particle collected on the collection sheet so as to increase fluorescence emitted from the particle. The fluorescence detection unit detects the fluorescence emitted from the particle which is collected on the collection sheet. The movement mechanism moves the collection sheet. With the configuration as described above, the particle detection device with which a measurement time period and the cost of measurement can be reduced can be provided.
