A cylindrical portion of an annular support member has a small-diameter portion press-fitted to an inner ring of a bearing, and a large-diameter portion formed by enlarging a part of the cylindrical portion, which is closer to an inboard side than the small-diameter portion. An annular magnet member has an inner-diameter side recessed portion formed by depressing, toward an outboard side, a radially inner part of a surface, in an inboard side, of the annular magnet member, and a wraparound portion that wraps around the annular support member toward the outboard side to a stepped portion between the small-diameter portion and the large-diameter portion. An inner peripheral surface of the wraparound portion protrudes radially inward more than an inner peripheral surface of the small-diameter portion. An inner peripheral surface of the inner-diameter side recessed portion has a gate mark of an inner-diameter side disk gate.

Magnetic encoder and method of manufacturing magnetic encoder

A magnetic encoder in which a support member and a plastic magnet do not adhere to each other is manufactured using a mold. The plastic magnet has a turning molded portion on the outer circumferential side thereof. The gate of the mold is an inner-diameter-side disk gate and a length L thereof in the axial direction is in a range of 0.2 mm&#x2264;L&#x2264;0.6 mm. The tensile strength of the material of the plastic magnet is 65 MPa or more and the Young's modulus thereof is 4000 MPa or more and 15000 MPa or less. The method includes a step of opening the mold and placing the support member as an insert object in the mold, and a step of closing the mold and injecting a melted material of the plastic magnet into a cavity through the disk gate.

The present invention is intended to provide an injection molding die that improves the strength of adhesion between an insert and a plastic in an insert molded article while suppressing fluctuations in the strength of adhesion. An injection molding die is used to manufacture an insert molded article by placing an insertwith a thermoset resin adhesive in the molding die and injecting a molten plastic material P from a gate G into a cavity C. The gate G is arranged at a position separated by 0.2 mm or more in an out-of-plane direction from a surface Aof the adhesive applied to the joining surface of the insert. During injection molding, the wall surface shear stress generated on the adhesive applied to the joining surface of the insertrelative to the plastic near the gate G becomes small. The adhesive is not swept away by the high-pressure molten plastic material P without having to bring the adhesive applied to the joining surface A of the insertinto the semi-cured state. Accordingly, it is possible to conduct injection molding without bringing the adhesive into the semi-cured state.

A radial-type magnetic encoder includes: an annular fixing member; and an annular plastic magnet attached to the annular fixing member. The annular fixing member includes the cylindrical portion, an outward flange portion extending outward in a radial direction from an edge of the cylindrical portion, and a sensor opposed portion bent from an edge of the outward flange portion and opposed to a magnetic sensor which detects rotation of the magnetic encoder, and the annular fixing member has a substantially U-shaped sectional shape along a plane including the radial direction and an axial direction. The annular plastic magnet has a shape that covers a front surface, a back surface, and an end edge of the sensor opposed portion, and an outer-diameter-side part of the outward flange portion.

A medical apparatus for making a subject learn the method of autogenic training and thereby treat an affected disease himself is disclosed. The apparatus can provide informing signals and physical stimuli to a subject, said signals and said stimuli are generated substantially in synchronism with each other for informing the subject with stimulus timing, and applying the stimulus to a concerned part of his body, respectively. Early in the sequence of such timing, the stimulus is completely correspondingly generated with the signal, meanwhile the stimulus is sometimes absent from the correspondence with the signal. In each of the stimulus absent times a significant bio-reaction is also caused by a conditioned reflex in the subject's physiology. This reaction is substantially the same to the normal reaction in the stimulus generating time. This will be connected with the self-learning of an associated autogenic training of the subject. The stimuli may comprise a therapeutic stimulus to a diseased part and a negative stimulus to reduce the therapeutic effect of the former. The therapeutic stimulus is sometimes absent from a stable timing for aiding the autogenic training of the subject.
