Abstract: A compact miniature fan has an air-guidance housing of rectangular parallelepiped configuration. The housing has two opposite end walls and side walls. One end wall is provided with an air inflow opening. One side wall is provided with an air outflow opening. The other end wall comprises a base plate. Mounted within the housing is an electric motor of flat overall shape. The stator and rotor of the motor define a planar air gap. The stator includes a magnetically conductive flux-return structure mounted on the base plate and a stator winding comprised of a plurality of flat coils mounted on the flux-return structure. The rotation axis of the rotor extends in the direction from one to the other of the end walls of the air-guidance housing. A radial fan wheel is provided within the housing, mounted on and coaxial with the rotor of the motor.

Abstract: A socket has a pair of spaced elongated side walls which extend lengthwise along a predetermined direction, and an upper and a lower wall located at respective opposite end regions of the side walls. The socket also includes a connecting wall extending intermediate the side walls and connecting the latter. The connecting wall is formed with a pair of passages which are spaced along the predetermined direction relative to each other by a predetermined distance. These passages are operative for receiving electrical pins connected to electrical motor wires and for mounting such wires at said predetermined distance relative to each other. The socket is insertable into a cutout of the housing and is connected to the latter by a resiliently yieldable element which is mounted on the upper wall of the socket. The socket also comprises a guide member on one of the side walls and a fixing member on the lower wall for respectively guiding and fixing the socket upon its insertion into the cutout of the housing.

Abstract: A magnetic tape recorder has two electric motors only, one of which is arranged selectively to drive one or other of two winding hubs depending on the direction in which a magnetic tape is to be transported and the other of which drives a tape drive capstan. The first motor is disposed non-co-axially with the axes of the hubs and the second motor, which is flat in shape and has at least four pairs of poles, is disposed alongside and at the same level as the first motor.
