The present invention makes clear and defines a congruent composition of a langasite-based oxide, and establishes a method of manufacturing a crystal by any desired composition of AEME(GaAl)SiO(AE is an alkaline-earth metal, ME is Nb or Ta, 0&#x2264;x&#x2264;1, &#x2212;0.5&#x3c;a&#x2264;0 or 0&#x3c;a&#x3c;0.5, &#x2212;0.5&#x3c;b&#x2264;0 or 0&#x3c;b&#x2264;0.5, and &#x2212;0.5&#x3c;c&#x2264;0 or 0&#x3c;c&#x3c;0.5, excluding a=b=c=0). This makes it possible to suppress the formation of an impurity, and improve the yield and crystal manufacturing rate. The raw material is a raw material mixture prepared by mixing an alkaline-earth metal or its carbonate or oxide, Nb or Ta or its oxide, Ga or its oxide, Al or its oxide, and Si or its oxide.

Crystal material and method of manufacturing the same

An operation device includes a support for pivotally supporting a shift lever, a first movable member configured to be pivotally operated from home position in a direction in conjunction with the shift lever, a pair of permanent magnets supported, at an operation reference position, by the support so as to be opposite the first magnetic body, and first plate springs for biasing the first movable member in a direction in which the first magnetic body moves toward the permanent magnets.

Operation device and vehicular shifting apparatus using operation device

A first movable member for pivotally shifting to a predetermined position in conjunction with a pivotal operation of a shift lever, and a permanent magnet section disposed so as to face the first movable member are included whereby the shift lever is provided with a click feeling given by an attraction force acting between the first movable member and the permanent magnet section. The permanent magnet section is magnetized such that in a thickness direction, an N pole and an S pole are created by magnetization in a series arrangement, and such that in a width direction, an S pole is created by magnetization alongside the N pole and an N pole is created by magnetization alongside the S pole created by magnetization in the thickness direction.

An operating device includes: an operation member capable of being tilted from an operation reference position; a support body supporting the operation member such that the operation member can be tilted first and second movable members each supported by the support body so as to rotate in conjunction with the tilting operation of the operation member; a first magnetic member formed of a magnetic material and provided to the first movable member; a second magnetic member fanned from a magnetic, material and provided to the second movable member; and a permanent magnet supported by the support body so as to face the first and second magnetic members in a first direction while the operation member is positioned at the operation reference position. The first magnetic member and the second magnetic member do not overlap each other seen from the first direction.
