Abstract: In a hands-free handset for a cordless telephone adapted for household use and including a base unit and a handset, the handset includes an automatic receiving and automatic hanging-up control loop, a voice loop and a port switching device. When the user plugs a speaker jack into a speaker socket of the port switching device, the voice loop will switch the voice signal to the automatic receiving and automatic hanging-up control loop, whereby the handset can automatically receive the voice signal or automatically hangs up.

Abstract: A case module for articles comprises an open top case chamber confined by a front wall, a rear wall, a left wall, a right wall, and a bottom wall, a front part disposed in front of the font wall, a rear part disposed in front of the rear wall, and a flat upper lid. The characteristics is in that the case module can be lifted in a state of opening by way of two lid projections on the upper lid being inserted between a beam groove in the rear part and the case chamber and the support device being inserted into the lid cover. Moreover, a right and left connection of the case modules can be performed by that the wall frame on the left wall of the one case module being inserted into the wall recess on the right wall of the another case module. A front and rear connection of the case modules can be performed by that a rear stick on the one case module is inserted into a front post of the another case module.

Abstract: A driving apparatus for a doll comprises a battery case containing at least one battery, a circuit board with an electronic switch, two opposite housing halves, and a driving part. Each of the housing halves at an inner wall thereof has an engaging hole, and two flips to form a groove. The driving part further comprises a left casing half, a right casing half, a right casing half, a motor, a speed reduction mechanism, and a swinging cam. The left casing half has an inner straight rail, an engaging projection at the top thereof, and a left engaging projection thereon to fit with the engaging hole. The right casing half has an upper part and a right engaging projection to fit with the engaging hole either. The motor with an output shaft being connects with the electronic switch. The speed reduction mechanism is formed by a belt and/or a gear shaft with an end thereof being associated with the output shaft on the motor and is provided with a swinging gear output shaft.

Abstract: A multi-function signboard includes a frame seat, a light seat, a light diffusion strip, a display board, a circuit board and a power source portion. The frame seat is a hollow light impermeable structure having a top portion that sinks downward to form a frame rib, and a frame groove, and has two ends respectively connected to an end cap. The light seat is an elongate seat that has connecting wires connected to the circuit board, and a plurality of light emitting diodes of different colors arranged in sets of three to provide light of different colors. The light diffusion strip is a transparent elongated strip with a length equal to that of the light seat, and is disposed on the light seat. The light diffusion strip and the light seat are together disposed in the frame groove. The diffusion strip is provided with semi-circular holes corresponding to the light emitting diodes to diffuse the colored light emitted by the light emitting diodes.

Abstract: A colored light mixing device, disclosed having at least one light source set and a color mixing plate. The light source set has three light generating units which generate light of different colors. The color mixing plate is made of transparent material, having a lower surface that faces the at least one light source set with a lower wavelike pattern and an upper surface opposite thereto with an upper wavelike pattern that is oriented differently from the lower wavelike pattern. Being hit by light from the at least one light source set, the lower wavelike pattern acts as a plurality of linear light sources for light of mixed colors inside the color mixing plate being illuminated by light from the lower wavelike pattern, the upper wavelike pattern emits light of uniform intensity and mixed hue.
