A magnet structure is a magnet structure for a TMR element which is an MR element. The magnet structure includes a bonded magnet compact that has a first main surface facing the TMR element, and a second main surface on a side opposite to the first main surface; and a tubular member that supports the bonded magnet compact. The bonded magnet compact has a gate portion which is provided on the second main surface and includes a gate mark formed by performing injection molding. The gate portion is provided at a position overlapping a center on the second main surface when seen from the second main surface side.

A magnet has a circular cylinder or circular tube shape and contains magnetic crystal grains, wherein an orientation of magnetization of the magnet is in a direction perpendicular to an axis of the circular cylinder or the circular tube, and directions of axes of easy magnetization of the magnetic crystal grains are isotropic.

A sintered magnet has an arc shape cross-section defined by an outer arc, an inner arc, and a pair of end sides connecting an end point of the outer arc and an end point of the inner arc, and a range of an central angle &#x3b1; of the inner arc is 145&#xb0;&#x2264;&#x3b1;&#x2264;180&#xb0;. The inventors have newly found that a large magnetic flux can be obtained according to the sintered magnet and the characteristics of the motor can be improved, using such a sintered magnet.

A process for producing a biocompatible material includes the steps of mixing an extract of a fish scale-derived hydroxyapatite (with water content of 70 to 75% by weight) and of a fish scale-derived collagen (with water content of 40 to 60% by weight) in the weight percent ratio of about 8:2, stirring the mixture and drying the mixture by a hot blast in order to obtain a composite.

Process for manufacturing biocompatible material

In order to provide a biocompatible material consisting mainly of a fish scale-derived hydroxyapatite and a fish scale-derived collagen, which is adjusted so that easily digested and absorbed in a human body, the material contains a composite consisting mainly of a fish scale-derived hydroxyapatite and a fish scale-derived collagen.
