Abstract: A manufacturing method of a semiconductor element includes forming a plurality of semiconductor layers on a sapphire substrate, each of the semiconductor layers having a first surface on the sapphire substrate side and a second surface on the opposite side, joining the second surfaces of the plurality of semiconductor layers to a retention member via an adhesive member, peeling off the plurality of semiconductor layers from the sapphire substrate by irradiating the first surfaces of the plurality of semiconductor layers with laser light, and polishing the first surfaces of the plurality of semiconductor layers. At least one semiconductor layer among the plurality of semiconductor layers includes a polishing indication part extending from the second surface toward the first surface. The polishing is executed until the polishing indication part is exposed to the polished surface.

Abstract: A print-data generating section generates print data in accordance with a high-resolution raster image generated by a high-resolution rasterizing processor. A low-resolution rasterizing processor generates a low-resolution raster image having lower resolution than that of the high-resolution raster image. An overcoating-data generating section generates coating data in accordance with the low-resolution raster image. Overcoating data is handled with low resolution, resulting in less processing time for overcoating than when the overcoating-data is handled with high resolution.

Abstract: An inkjet printer includes an image-forming part, forming an auxiliary layer on a base material by ejecting droplets of auxiliary ink and forming an image on the auxiliary layer by ejecting droplets of image-forming ink, the auxiliary ink changing a dot formation state of droplets of the image-forming ink. In a storage part, a reference table that associates each of a plurality of types of base materials with a proper dot area rate to be used when forming the auxiliary layer is stored. In a dot-area-rate determination part, a dot area rate to be used when forming the auxiliary layer on a target base material is determined as an auxiliary ink dot area rate by referencing the reference table using the type of the target base material. This enables the inkjet printer to form a highly precise image on various base materials.

Abstract: Depending on the lateral width thereof, an image recording material P is stably positioned on a recording drum, employing two positioning pins with an appropriate pitch therebetween. Non-contacting portions prevent any irrelevant positioning pins from coming into contact with the material P. The material P may be transported onto the recording drum 5 while one end thereof constitutes an angle U with a rotation axis 5N of the recording drum 5. A reference notch 44ae first fits with a positioning pin 51a. Thereafter, as the aforementioned end of the material P abuts with a positioning pin 51b, accurate positioning occurs. Each positioning pin 51 includes a tapered portion having a reference taper angle 2T. When a leading-end clamp 52 clamps the aforementioned end, the material P comes in contact with the tapered portion, with a, reduced friction force against the positioning pin 51, thereby preventing deformation of the material P.

Abstract: Provided is a drum surface scanner with which punched holes and/or cuts can be formed in a plate which has been correctly defined by position, and the plate can be clamped to a recording drum. When a plate P comes in front of movable pins 113, i.e., on a hole punch unit 4 side, the upper roller of a conveyor roller 125 moves down, and conveyor rollers 124 and 125, and conveyor belts 111 all start rotating in the positive direction. Once the plate P moves out of the range covered by a sensor PH159, the movable pins 113 follow the tail end of the plate P at a given distance therefrom. When the front end of the plate P reaches the hole punch unit 4, the movable pins 113 which have been chasing the plate P push the tail end thereof to make the front end thereof abut to the hole punch unit 4. At the same time, based on the movement amount of the movable pins 113 from their original positions to current positions pushing the tail end of the plate P, the plate P is checked for its length Y.

Abstract: Annular grooves are formed on both end surfaces of a recording drum to be rotated, and two balance weights are disposed inside each of the annular grooves. The balance weight is composed of a magnet, and is attracted to the end surface of the recording drum by its magnetic force. The two balance weights are arranged at a predetermined attaching angle such that an unbalance force caused by centrifugal forces developed by a plate, a movable clamp, and so forth is canceled. Every time the size and the mass of the plate are changed, the positions of the two balance weights are adjusted, so that forced vibration in the recording drum is restrained.
