Abstract: A susceptor assembly for supporting a crucible during a crystal growth process includes a susceptor base, a tubular sidewall connected to the susceptor base, and a removable sacrifice ring interposed between the susceptor base and the sidewall. Each of the susceptor base and the sidewall is formed of a carbon-containing material. The susceptor base has an annular wall and a shoulder extending radially outward from an outer surface of the annular wall. The sidewall has a first end that receives the annular wall to connect the sidewall to the susceptor base. The sacrifice ring has a first surface that faces the outer surface of the annular wall, a second surface that faces an interior surface of the sidewall, and a ledge extending outward from the second surface that engages the first end of the sidewall.

Abstract: An electronic device is provided. The electronic device includes a first substrate and a first pattern layer. The first substrate has a first surface and a second surface opposite to each other. The first pattern layer is disposed on the first surface and includes a first grid region and a second grid region. The first grid region includes multiple first grids. The second grid region includes multiple second grids. The first grid region is connected to the second grid region. One of the first grid and the second grid includes a metal grid. The other one of the first grid and the second grid includes a non-metal grid. The electronic device of the embodiment of the disclosure can improve appearance.

Abstract: A joystick used in a motion apparatus, for example, an exerciser or game machine, is disclosed to include a base fixedly fastened to the body of the motion apparatus, a motion member fixedly fastened to the operating member of the motion apparatus for biasing with the operating member by the user, elastomeric members connected between the base and the motion member, and a control member coupled to the motion member and movable relative to the motion member to lock the motion member to the base or to adjust the maximum biasing angle allowable for the motion member and the operating member.

Abstract: In a wheelchair training platform, a wheelchair is connected to a computer system through the training platform, and the training platform detects signals of a rotary speed and a forward direction or a reverse direction of two rear wheels of the wheelchair, and sends the signals to a computer system. The computer system reflects the foregoing rotary speed and direction to a virtual reality interactive software/game, such that the wheelchair has an interaction with the virtual reality interactive software/game.
