A communication apparatus comprises a memory storing instructions which cause to function as: a first communication unit configured to communicate with an external apparatus using a first communication method in which directionality of radio waves is variable; a second communication unit configured to communicate with the external apparatus using a second communication method in which directionality of radio waves is variable; and a control unit configured to control the first communication unit and the second communication unit so as to, after communication using the first communication method has been established, switch communication with the external apparatus to communication using the second communication method, wherein the control unit controls directionality of second radio waves in the second communication method, using information regarding directionality of first radio waves used in the first communication method.

Communication apparatus that uses plurality of communication methods, method for controlling the same, and storage medium

First and second magnets are provided in a movable unit that is coupled with a body, the movable unit being rotatable with respect to the body around a first axis and a second axis that is substantially perpendicular to the first axis. First and second magnetic-field sensors are provided in the body. Based on output signals of the first and second magnetic-field sensors, control is performed in accordance with a state of the movable unit with respect to the body.

Electronic device

An image display apparatus includes an image display device having a drive control unit capable of changing a scanning direction, and an image processing device for performing image processing on an inputted image signal to output the processed image signal to the image display device. In addition, a setting device adjusts an image processing setting of the image processing device correspondingly to the scanning direction of the image display device.

Image display apparatus and setting method of image display apparatus

A method for manufacturing a head stack assembly that includes a pair of suspensions each of which supports a head, an arm that drives the head, and a pair of base plates that attach the pair of suspensions to both sides of the arm that has a perforation hole, each of the pair of base plates having a boss with an opening includes the step of swaging the pair of base plates with the arm by passing, in one direction, a processing member larger than the opening through the perforation hole and the base plates while the pair of base plates are being inserted into the perforation hole at both sides of the perforation hole, wherein where a neutral plane is defined as a plane that halves a thickness of the arm and is perpendicular to a section that includes a center axis of the perforation hole, a first position is defined as a position that has a minimum internal diameter of the base plate, and a second position is defined as a position closest to the neutral plane among contact positions between the base plates and the arm, a distance between the neutral plane and the first position is equal to or smaller than a distance between the neutral plane and the second position before the swaging step.

In an ink jet print head including a plurality of ejection openings arranged therein for ejecting an ink, with the head carrying out printing by moving in a scanning direction relative to a printing medium, an ejection failure is detected promptly and accurately and adhesion of the ink to an ejection face on which the ejection openings are formed is also detected, without affecting print operation sequences. To achieve this, the following operations are performed: While an ink jet print head is being relatively moved in the scanning direction, a light beam is supplied diagonally of an arrangement direction of the plurality of ejection openings and in a direction traversing a trace of the ejected ink. The ink is ejected through the plurality of ejection openings in accordance with predetermined data, and a manner of ink ejection from each of the plurality of ejection openings is detected based on how the ejected ink is blocking the light beam. Based on the detection contents, it is also determined whether or not the ink adheres to the ejection face.

Ink jet printing apparatus and a judgement method of an ink ejection state of an ink jet head

A magnetic head assembly including a carriage arm and a spring arm having at least one magnetic head attached thereto. The spring aim is provided with a cylindrical member including a thin plate member having a trapezoidal cross-section provided at one end thereof. The structure of the spring arm enables the spring arm to be removably attached to a carriage arm of the magnetic head assembly.
