Packaging for automated supply of a brushless motor

A motor includes a stator and a rotor facing the stator. The rotor has a magnet and an eccentric weight. The magnet is magnetized in a rotational direction and produces driving magnetic field. The eccentric weight is made of the material having a greater specific gravity than the magnet. The magnet shapes in a cylinder and a part of the cylinder is cut away to form a space. The eccentric weight is placed in the space. A rotational area of the magnet and that of the eccentric weight overlap each other. In this structure, rotation of the rotor spins the eccentric weight, thereby producing large vibrations. The eccentric weight is accommodated by a motor housing for the safety. The thin and compact motor is thus obtainable.

A motor includes a rotor, a stator facing to the rotor, a motor-base-assembly for journaling the rotor and holding the stator. The motor-base-assembly is made of resin and includes a motor-base having openings and terminals made of metal. These terminals are inserted into the openings to be mated with the motor-base, and lower faces of the terminals are exposed from the bottom of the motor-base. This structure allows the terminals to be mated with the motor-base without using an insert-molding method, and permits high productivity of the motor. This advantage appears conspicuously in such a small motor, among others, as can be directly re-flow soldered to a board of a device. The device employing this motor enjoys high productivity and reliability because the motor can be directly re-flow soldered to the board of device.

A motor includes (a) a stator having a stator core wound with a coil, (b) a rotor having a magnet facing the stator core via an annular space and a yoke disposed on an outer wall of the magnet, and (c) an unbalancing weight disposed on an outer wall of the yoke. This structure allows the motor to be small in size, light in weight, thin, flat and to function as a vibrating motor producing maximum vibration at low power consumption. The motor thus contributes to realizing a portable device with a small size, a low weight, and which is operable for many hours.

A liquid crystal display comprises as liquid crystal panel having a liquid crystal layer disposed between electrode layers, polarizers disposed at both sides of the panel, and a solid birefringent film having the maximum refractive index direction varying with its depth and disposed at at least one side of the liquid crystal panel between the polarizers. The solid birefringent film conpensates the dependence of the polarization characteristic on wave length, thus being capable of obtaining either a monochrome display or a display having an extremely low coloration.
