摘要： A rotation angle detecting device includes a magnetic member for providing a magnetic field, a magnetic sensor for sensing a change in the magnetic field when the magnetic member rotates relative to the magnetic sensor about a rotation axis. The magnetic sensor is disposed at a single position and includes a pair of sensor elements. The pair of sensor elements is disposed on an imaginary plane that is perpendicular to the rotation axis so that sensing surfaces of the sensor elements have 90 degrees in angle to each other and so that each of the sensing surfaces inclines by 45 degrees in angle to a line intersecting the rotation axis at right angles.

摘要： A rotation angle detector for detecting change in the magnetic flux has a magnetic sensor being disposed at a position in a space between an outer surface of a shaft and a periphery of the magnetic flux generation means. A supplementary magnet is also used in a space that is enclosed in a circular trace of the magnetic sensor around the shaft for even distribution of the magnetic flux generated by the magnetic flux generation means.

摘要： A method of removing a molded article, which makes it possible to remove easily said molded article without causing deformation and damages thereto and an apparatus for same. The method comprises removing a sand core W which is obtained using a sand core forming mold 12 comprising a fixed and movable molds 21 and 31 from a sand core forming mold 12 by a separating movable mold 31 from the fixed mold 21 to perform a mold opening. The fixed mold 21 is provided with a fixed mold side core 23 having a front end face 23a forming a part of a first molding face 22, which is extendable and retractable in a mold opening direction A1. The movable mold 31 is provided with a movable mold side core 33 having a front end face 33a forming a part of a second molding face 32, which is extendable and retractable in a mold opening direction A1. The relation in which the sand core W is held between both cores 23 and 33 is kept by extending both cores 23 and 33 in a mold opening direction A1.

摘要： A solution of material for the desired crystal is filled in a growth tank having two ion-exchange membranes which define a crystal growth vessel between them and two side vessels on opposite sides of the crystal growth vessel, and the growth tank is placed in an outer tank while filling a fluid therebetween. During electrodialysis in the growth tank, the crystal growth vessel solution temperature T.sub.c, the side vessel solution temperature T.sub.o, and the fluid temperature T.sub.w between the tanks are controlled so as to keep the conditions of T.sub.o >T.sub.c >T.sub.w.
