A magnetic sensor device includes a magnet that generates a magnetic field and sets of magnetoresistive elements arranged in a longitudinal direction that is perpendicular to a transport direction. Each of the sets of magnetoresistive elements includes a first and a second resistor. A midpoint of the first and the second resistor is matched with a center axis of the magnet in the transport direction. The first and the second resistor are arranged such that the distance therebetween increases from a distance between first ends of the first and the second resistor in the longitudinal direction to a distance between second ends of the first and the second resistor in the longitudinal direction. At least two sets of the first and the second resistor are arranged so as to be axisymmetric with respect to an imaginary line that is perpendicular to the longitudinal direction of the magnet.

Magnetic sensor device

A static magnetic field generator generates a non-magnetic field region. An AC magnetic field application instrument applies an AC magnetic field to the non-magnetic field region. A detection coil has an axis parallel to a direction of the AC magnetic field in order to detect a magnetization signal. A measuring instrument is connected to the detection coil. A resonance frequency variable device includes a capacitor connected in parallel to the detection coil in order to adjust a resonance frequency of the detection coil and the measuring instrument. A capacity of the capacitor is adjusted such that a resonance frequency of a closed circuit including the detection coil, the measuring instrument, and the resonance frequency variable device including the capacitor coincides with a frequency of a harmonic signal.

Magnetic particle imaging device

A magnetic particle imaging system includes a field free region generator and an excited magnetic field generator. The field free region generator generates a field free line with a direction of linear extension of a field free region as a direction of extension. The excited magnetic field generator generates an excited magnetic field in the field free line generated by the field free region generator. The excited magnetic field generator includes a first excited magnetic field generation unit and a second excited magnetic field generation unit. The first excited magnetic field generation unit and the second excited magnetic field generation unit are spaced from each other in the direction of extension of the field free line.

Magnetic particle imaging system and magnetic particle imaging method

A first magnetic field generator generates a magnetic field intersecting a detection object being transported along a transport path. A second magnetic field generator opposite to the first magnetic field generator with respect to the transport path generates a magnetic field intersecting the detection object. A first magnetoresistive element between the first magnetic field generator and the transport path outputs, as a change in resistance, a change in magnetic flux density produced by transport of the detection object. The first and second magnetic field generators are different in a magnetic pole facing the transport path and are arranged with a center of the first magnetic field generator in a transport direction of the detection object and a center of the second magnetic field generator in the transport direction are located at mutually different positions. The first magnetoresistive element includes a first resistor and a second resistor arranged with spacing therebetween.

A manually sweepable printer stores data transferred from a data forming apparatus such as a wordprocessor in a memory. The printer is placed on printing paper and manually swept to sequentially print the data stored in the memory. The manually sweepable printer separately receives printing data and print control data from the data forming apparatus and separately stores the received data. In the printing operation, the printing data is printed on the basis of the print control data.

Manually sweepable printing apparatus

A manually operable sweeping-type compact printer apparatus includes a key entry unit, a display unit, a memory unit, an encoder and a printer unit which are mounted on a manually manipulatable housing. When the housing is manually moved over a printing medium with the printer unit in contact with the printing medium, data entered by the key entry unit is printed out on the printing medium. In the printer apparatus, only designated segments or lengths of data are printed out on the printing medium, independent of continued travel or movement of the housing. Also, even if the housing is moved over the printing medium at an unstable moving velocity, high printing quality can be realized by control of the printing head. Stop codes designating the end of a data segment can be automatically or manually inserted.

Hand-held manually operable printing apparatus

A manual sweeping apparatus comprising a housing, rollers which can rotate in contact with an original or a sheet of paper, an image sensor, a printer, memories, and a key-input section. When the housing is swept across an original, with the rollers kept in contact with the original, the image sensor reads the image information from the original. The image information is stored in one of the memories. Character data is input by operating the key-input section, and is stored in another one of the memories. Thereafter, when the housing is swept across a sheet of paper, with the rollers kept in contact with the paper, both the image data and the character data are printed, in a combined form, on the sheet of paper.
