A centrifugal fan module is provided. The centrifugal fan module includes a housing, a blade unit, a heat sink and a vapor chamber. The housing includes a bottom cover, a sidewall, a top cover and an outlet structure, wherein the bottom cover is connected to the bottom of the sidewall, the top cover is connected to the top of the sidewall, and the outlet structure is connected to the top cover and the sidewall. The blade unit is disposed in the housing, wherein the blade unit is located between the bottom cover and the top cover. The heat sink is disposed on the vapor chamber, the heat sink is located between the vapor chamber and the top cover, and the heat sink is located between the outlet structure and the blade unit.

A viscous flow blower includes a housing including an inlet, an outlet, a motor, and an internal space; a seat secured to the housing and including N supporting projections and an axis of rotation. N is an integer equal to or greater than five. The connection member is coaxial with the axis of rotation. The motor is operatively connected to the seat so that the seat can be rotated by activating the motor. Annular blades are stacked on the seat. The blade includes a plurality of through holes with the supporting projections inserted through and secured thereto respectively. The N supporting projections are spaced from the axis of rotation by a predetermine distance. There are N angles formed by the supporting projections. The N angles all have different degrees. It can reduce suddenly sharp increases in amplitude of noise at certain frequencies.

A keyswitch includes a base, a keycap, a lift mechanism, a touch circuitry portion, and an outer covering layer. The keycap is connected to the base through the lift mechanism so as to move up and down relative to the base. The touch circuitry portion is disposed on the top surface of the keycap. A connection circuitry portion extends from the touch circuitry portion. The outer covering layer covers the touch circuitry portion and at least a portion of the connection circuitry portion. Thereby, the keyswitch can provide touch function without excessively increasing the whole thickness of the keyswitch. A keyboard includes a plurality of the keyswitches and therefore can provide touch function without excessively increasing the whole thickness of the keyboard.

A waterproof film includes a film reinforcing layer, a light shielding layer, a texture layer, and a pattern. The light shielding layer is combined under the film reinforcing layer and forms a plurality of protruding structures cooperatively with the film reinforcing layer by a hot pressing process. The texture layer is attached to a release film and then formed on a top surface and a side surface of each protruding structure after a hot pressing process is performed and the release film is then peeled. The pattern is formed on the texture layer or the light shielding layer.

Waterproof film and keyboard thereof

A micro fan is provided. The micro fan includes a rotor and a stator. The stator includes an axial induced coil unit and a circuit board. The axial induced coil unit is made by twining a coil in an axial direction for at least two layers and in a radial direction for at least two layers.

Micro fan

A method for fabricating a keyboard covering film is provided. The method includes steps of: coating a transparent plastic material on an upper surface of a fabric layer before the transparent plastic material is cured; treating the fabric layer and the transparent plastic material by a hot press process to cure the transparent plastic material to form a transparent layer and to make the transparent layer and the fabric layer jointly form a number of keycap receiving sections; forming a mask layer on a lower surface of the fabric layer; removing a portion of the mask layer and a portion of the fabric layer located within each of the keycap receiving sections to form a number of hollow patterns.

Method for fabricating keyboard covering film

A keyboard covering film including a fabric layer, a transparent layer and a mask layer is disclosed. The transparent layer is disposed on an upper surface of the fabric layer. The mask layer is disposed on a lower surface of the fabric layer. The transparent layer and the fabric layer are treated by a hot pressing process to form a number of keycap receiving sections. The keycap receiving sections, the fabric layer and the mask layer are located on the same side of the transparent layer. The fabric layer and the mask layer have hollow patterns within the keycap receiving sections, wherein the hollow patterns are formed by removing a portion of the fabric layer and the mask layer.
