Abstract: A support structure for a rotation driving system having a ball balancer includes: a motor having a rotational shaft coupled to a rotational shaft of a rotor; the ball balancer provided on the rotor to reduce oscillating motion of the rotor; and a support part for coupling the motor to a housing, wherein the motor is coupled to the housing via an elastic member on a line in one direction (x-axis) perpendicular to an axial direction (z-axis) of the rotational shaft of the motor, and the motor is allowed to swing about the x-axis due to elastic deformation of the elastic member.

Abstract: To propose a centrifugal separator that is capable of performing, easily and accurately, a condition setting operation for continuously operating the centrifugal separator under a plurality of operating conditions. In the centrifugal separator, which stores operating conditions in a plurality of memories respectively and independently or continuously calls up the operating conditions stored in these memories to perform operation control, a plurality of memory selection keys corresponding to the plurality of memories are provided, and the memories for storing the operating conditions therein and the memories for calling up the operating conditions are specified by selecting the memory selection keys.

Abstract: A rotor mounting structure arranged in a centrifugal separator. A cylindrical shaft having elastic tongue pieces provided substantially equidistantly on the peripheral edge of the upper surface of the cylindrical shaft is provided at the distal end of a drive shaft; the tongue pieces have hooks; a shaft accommodation orifice accommodates the cylindrical shaft is formed in the center of the rotor; elastic tongue piece insertion grooves mate with the elastic tongue pieces of the cylindrical shaft; the rotor is joined to the cylindrical shaft, while bending the elastic tongue pieces; and in a state in which the rotor is completely joined to the cylindrical shaft by engaging the hooks of the elastic tongue pieces with the upper edges of the grooves of the rotor by the elastic force of the elastic tongue pieces.

Abstract: A slide glass rack for use in a centrifugal apparatus has a slide glass accommodating concave that opens upward, and a flange provided on an upper outer peripheral surface of the rack. A centrifugal apparatus that uses the slide glass rack comprises a rotor, wherein the rotor is formed at a peripheral edge thereof with an inclined face extending upward obliquely with a predetermined angle, the inclined face being formed with a rectangular hole through which a slide glass rack is inserted, the flange of the rack is supported by the peripheral edges of the rectangular hole.

Abstract: The present invention relates to a device for inserting a brain electrode which makes it easy to install the device and to insert the brain electrode and yet allows the electrode to be inserted with sufficient precision. The present invention is a brain electrode securing device, in which an electrode-wire-type electrode held by an electrode holder is inserted into the brain through a hole formed in the skull for the purpose of measuring changes in electrical potential at an electrode at a measuring location inside the brain, and the device comprises a casing which is securely mounted on the skull so as to surround the aforementioned hole, an electrode holder which is arranged so as to slide freely in relation to the aforementioned casing, and a screw rod which is screwed approximately to the center of the electrode holder and is supported so as to rotate freely in relation to the aforementioned casing.

Abstract: A centrifugal separator having a cylindrical bottomed main rotor body, and a rack configured with a plurality of rack parts along the inner circumferential surface of the main rotor body, which rack parts are linked together and are able to move in radial directions of the main rotor body, so that when the main rotor body is rotated, the rack parts are pressed against the inner circumferential surface of the main rotor body and held there by the centrifugal forces associated with the rotating of the main rotor body.

Abstract: A game capable of receiving and then seemingly randomly dispensing objects includes a housing which has an accumulator chamber located therein. The accumulator chamber can receive individual objects, accumulate them, and then dispense the objects so accumulated. An activation member is mounted on the housing in association with the accumulator chamber. Further, a chance member is mounted on the housing in association with the activation member. The chance member is capable of moving between a plurality of positions, at least one of the positions being a dispensing position. The activation member moves the chance member on the housing between its positions in response to reception of one of the objects in the accumulator chamber by the depositing of the object in the accumulator chamber. Objects are accumulated in the accumulator chamber as they are so deposited, with the chance member being moved with the deposition of each of the individual objects.

Abstract: This invention provides a device for driving a simulated flying object such as a toy aircraft, which is capable of causing the object to make a loop-the-loop flight as well as a circling flight. The device is also capable of causing the object to ascend and descend, repeatedly.

Abstract: This invention, which provides a folding bicycle, comprises a foldable frame structure including a front support assembly having handlebars and arranged to be rearwardly foldable. According to the invention, the user can very quickly and easily fold the bicycle by manually rearwardly folding the front support assembly which includes upper and lower sections interconnected by a hinge.

Abstract: There is disclosed a baby walker to be used by a child wherein the body of the child is supported above the ground so that the feet of the child are in contact with the ground, thus permitting the child to propel the baby walker. The baby walker comprises means for permitting the walker to be collapsed or expanded, and means for locking said collapsing and expanding means to fix top and bottom members of the baby walker in a desired one of several positions. In this manner, the seat supporting the child is adjustable so that the distance to the ground may be controlled for different sized children, or for the same child over a period of growth.
