Abstract: There is provided a printing apparatus, including: a base; a thermal head including heating elements arranged in a first direction; a head holding member disposed to be slidable on the base in a second direction intersecting with the first direction and a third direction intersecting with the first direction and the second direction; a rolling member; a first pivoting member; a second pivoting member; a first guide rail extending in the second direction; a first sliding member held by the first guide rail to be slidable on the base in the second direction and having a contact surface which is in contact with the rolling member from a first side in the third direction; a first movement mechanism configured to pivotally move the first pivoting member and the second pivoting member; and a second movement mechanism configured to move the head holding member in the second direction.

Abstract: A sheet tray, including a tray body having a bottom plate, and a sheet guide, is provided. The sheet guide includes a guide plate to align sheets at a predetermined position, a lever, a swingable device having a boss and a guide groove, and a stopper pivotably connected with a hinge. The boss guided in the guide groove moves the lever between a first position, wherein the boss is in a first section in the guide groove and the stopper is lowered to an engaged position, with an engageable part being engaged with the bottom plate; and a second position, wherein the boss is in a second section in the guide groove and the stopper is uplifted to a separated position with the engageable part being separated from the bottom plate. When the lever moves from the first position to the second position, the lever tilts by ascending and pivoting.

Abstract: There are provided a method for detecting an abnormality of a resolver, an angle detection device, a motor, and a transportation device, by which the abnormality can be detected promptly without the necessity of any complicated operations. There is provided a circuit configured to switch between a sine wave and a direct current voltage to be supplied, as an excitation signal of a resolver (2). Then, immediately after the power is turned on, the direct current voltage is applied to the resolver (2), and the output voltages of the phases of the resolver (2) are measured when the direct current voltage is applied. In this situation, the output voltages of the phases are compared with each other. When none of them matches each other, it is determined that an abnormality (short-circuit abnormality, short-circuiting) occurs at the resolver (2).

Abstract: There are provided an angle detection apparatus configured to correct an error included in angle information output from a multipolar angle detector, a motor having the angle detection apparatus, a torque sensor, an electric power steering apparatus, and a vehicle. A multiplication circuit (12) generates digital electrical angle information (?ed) from analog angle information output from a multipolar optical encoder (11), a first differentiator 30 differentiates the electrical angle information (?ed) to operate an electrical angular velocity (?ed), a first discontinuity correction circuit (31) carries out processing of correcting a discontinuity of an angular velocity in a temporal change for the electrical angular velocity (?ed), and a digital filter (32) carries out correction processing of reducing a high-frequency noise component for an electrical angular velocity (?edc) corrected by the first discontinuity correction circuit (31).

Abstract: Facsimile apparatus stores, in a memory, a telephone number for connecting to a server of an Internet facsimile transmission service company. The facsimile apparatus transmits facsimile signals via the Internet, a registration number of a user of the service company, a facsimile number of the destination, and a protocol for connecting to the service company. Connection to a server of the service company is established by pressing a button and further processing for connection with the Internet is executed. The server of the service company converts the image information of the facsimile signals as received from the facsimile apparatus into image data of its own format appropriate for Internet transfer, selects a second server which is located close to the destination based on the destination facsimile number, and transfers the data via the Internet. The second server reconverts the image data into a format conforming to the destination facsimile, connects to the destination facsimile, and transmits the data.
