Abstract: A gearing switch device includes a switch assembly that is switched to one of positions to engage one of the gears in an idle gear set with an input gear and a transferring gear of a speed reduction device. The transferring gear drives a ring gear that is engaged with planetary gears device connected to one side of a disk and an output gear is connected to the other side of the disk. By the different types of engagement between the gears of the idle gear set and the transferring gear, the speed of the disk is changeable so as to have desired output torque.

Abstract: An electromotive linear drive mechanism, in particular a drive mechanism for a body of furniture, includes an electric motor having an output journal and a rotating spindle which has mounted thereon a nut, secured against rotation. The nut is operatively connected to the body of furniture, for movement in longitudinal direction of the spindle when the spindle rotates. A worm drive includes a worm which rotates about an axis of rotation and is in engagement with the output journal of the electric motor. Connecting the worm drive to the spindle are at least two worm gears which are in engagement with the worm and arranged in symmetric disposition with respect to the rotation axis of the worm. Each worm gear which is connected to a cylindrical gear is in operative engagement with the respective cylindrical gear meshing with the other worm gear.

Abstract: A camera includes a plurality of camera operation mechanisms, a sun gear which rotates by means of a motor, a planetary gear which revolves around the sun gear, and a plurality of output gears each capable of meshing with the planetary gear by means of revolution of the planetary gear. The plurality of output gears transmit power to the plurality of camera operation mechanisms, respectively. An unlocking device removes backlash by causing the planetary gear to rotate temporarily in an opposite direction when the planetary gear is to be switched from one of the plurality of output gears in mesh therewith, to another one of the plurality of output gears. A locking device prevents the planetary gear and such one output gear from coming out of mesh with each other until the backlash is removed when the unlocking device causes the planetary gear to rotate in the opposite direction.

Abstract: A device, having a planetary gear and a single motor, in use for switching and transmitting a driving force of the motor to any one of station gears and for driving each station gear in both rotational directions. The operation of locking levers for preventing a planetary gear from revolving around a sun gear is controlled by a cam. The cam is actuated by a driving force of the motor. A spring frictionally connecting the cam and an output shaft of a speed reduction system is interposed therebetween, and a magnet is disposed so as to restrict the movement of the cam when the motor rotates. A sun gear is connected with the output shaft of the speed reduction system with a "play" or gap in order that the rotation of the sun gear is reversed behind time corresponding to the play when the rotation of the motor is reversed, thus making it possible to start actuating the cam earlier than the sun gear for making sure that the locking levers are shifted.

The holding member includes a moving member rotatable in interlocked relation to the revolution of the planetary gear. The holding member switches from the first state to the second state by means of a movement of the moving member in a direction different from a direction of rotation of the moving member.

Abstract: A gear drive with variable gear ratio employs a set of idler gear shafts eccentrically mounted on rotating disks surrounding input and output drive shafts. Simple rotation of the disks engages and disengages, in sequence, different idler gear assemblies as mounted on the disks, with and from both the input and output drive shafts providing a simple changing of gear ratio and eliminating unnecessary turning of idler shafts not used for the direct transmission of power.

Abstract: A driving force transmission mechanism and method according to the present invention transmits the driving force of a single motor selectively to a plurality of driven gears, comprising a sun gear rotated either in a forward or reverse direction by the motor, a planetary gear engaging the sun gear, and a plurality of driven gears arranged along the revolution orbit of the planetary gear. A driven gear with which the planetary gear is desired to engage is selected by rotating the sun gear in one direction. The driving force is transmitted to the selected driven gear via the planetary gear by rotation of the sun gear in the opposite direction. The proper gear is selected by use of a sensor. Using the driving force transmission mechanism, various driving systems can be driven by a single motor without the need for a complex switching mechanism. The transmission mechanism may use more than one planetary gear and may use more than one planetary gear assembly.

Abstract: A voice actuated toy robot receives commands via a radio transmitter and receiver, and in response to receipt of these commands propogates a signal through a CPU. Initially the toy is programmed by storing records of commands in a memory which is associated with the CPU. Upon further receipt of identical commands, the CPU scans the memory and upon finding a match between a record in the memory and a new command, the CPU activates a switch associated with the record in the memory so as to set the switch. A mechanical interogator is capable of cycicly interogating a plurality of switches each of which corresponds to one of the records in the memory. Upon interogation of the switches, if it is determined a signal is present at one of the switches, the interogator ceases interogation and a mechanism is set so as to propogate motion from a motor to an appendage driving wheel or the like of the robot to produce an output in response to the audio command which was received.

Abstract: A condiment mill has a pair of separate compartments each for containing a different condiment, such as peppercorns and salt crystals. At the bottom of each compartment, a grinder is installed for grinding the condiment. A shaft is provided for rotatably driving each of the grinders, each such shaft extending upwardly through its associated compartment and having a spur gear fixedly attached to the upper end thereof. A pivotally supported gear drive mechanism is provided at the top of the compartments which engages the gear of one of the grinders when rotated in one direction and the gear of the other of the grinders when rotated in an opposite direction to enable the alternative grinding and dispensing of one or the other of the condiments. A cover is provided for the top of the compartments, this cover being spring-urged into its closed position over the compartments. This cover can be manually raised against the spring action and rotated to permit the filling of the compartment with condiment.
