摘要:
A printing apparatus comprises a movement unit which moves a carriage incorporating a print head along a carriage shaft arranged in a main scanning direction, and a conveyance unit which conveys a printing medium in a sub-scanning direction perpendicular to the main scanning direction. The printing apparatus stores image data. The image data is divided into a plurality of first image data in the main scanning direction and the sub-scanning direction, and is read out. Predetermined image processing is executed based on the first image data and first image data adjacent to the first image data in the sub-scanning direction. Second image data is extracted, based on information about a deflection of the carriage shaft in the sub-scanning direction, from the first image data for which the image processing has been executed. The extracted second image data is transferred to the print head.

A rotor core has installation portions in which first magnets, which are permanent magnets, are arranged. The installation portions are larger than the first magnets. The first magnets are divided into a first group and a second group. The first magnets in the first group are fixed to the installation portions to be offset in the positive rotational direction of the rotor toward the pseudo magnetic poles or the different magnetic poles. The permanent magnets in the second group are fixed to the installation portions to be offset in the inverse rotational direction of the rotor toward the pseudo magnetic poles or the different magnetic poles.

A method for manufacturing a liquid discharge head including an energy generating element, which generates energy utilized for discharging a liquid, and a discharge portion provided at a position facing the energy generating element and having a discharge port for discharging the liquid is provided. This method includes the steps of forming a negative photosensitive resin layer used for a member that forms the discharge port on the substrate, and exposing the layer to an i-line to form the discharge portion that is tapered in a direction from the substrate to the discharge port, wherein the layer has an absorbance per 1 μm thickness of about 0.02 to about 0.07 for light used for the exposure.
摘要:
An antenna unit includes a feeding component 40 and a metal plate 50 on which the feeding component 40 is mounted. The feeding component 40 has an attaching member 43 made of resin to support a feeding line against the metal plate. The metal plate 50 has a pair of cut and raised parts 51 at both ends thereof while the attaching member 43 has a pair of locking hooks 432 at both ends thereof. The locking hooks are partly inserted into the cut and raised parts and thereby the feeding component is attached to the metal plate without projecting any parts of the attaching member from a rear surface of the metal plate.
