Abstract: A wheel control mechanism includes a support base, a wheel module, a first magnetic module and a second magnetic module. The wheel module, the first magnetic module and the second magnetic module are installed on the support base. The first magnetic module generates a magnetic attractive force to attract a metal ratchet of the wheel module. By adjusting the position of the second magnetic module relative to the first magnetic module, the strength of the magnetic attractive force is changed. Consequently, the rotation of the wheel module results in a tactile feel or does not result in the tactile feel.

Abstract: A light emitting diode package structure including a base, a light emitting diode and an encapsulant is provided. The light emitting diode is disposed on a surface of the base and is adapted to generate and emit a light. The encapsulant is disposed on the base and encapsulates the light emitting diode. The encapsulant has a surface parallel to the surface of the base and a plurality of surfaces perpendicular to the surface of the base. The light, after passing through the surface of the encapsulant parallel to the surface of the base, has a first light intensity. The light, after passing through the surfaces of the encapsulant perpendicular to the surface of the base, has a second light intensity. The first light intensity is greater than the second light intensity. In addition, a manufacturing method of a light emitting diode package structure is also provided.

Abstract: A device for manually controlling a power window of an automobile including a connector formed with a cavity at a lower end and a rectangular recess at an upper end, a sleeve fixedly fitted on a bearing mounted on an upper end of an electric motor, a flexible tube having a lower end fixedly engaged with the sleeve, a ferrule inserted through a covering panel mounted at an inner side of an automobile door so as to engage with the other end of the flexible tube, and a turning mechanism including a handwheel, a tubular member disposed at one side of said handwheel, and a cable extending through the tubular member to engage with a central portion of the handwheel and having a rectangular lower end adapted to engage with the rectangular recess of the connector.

Abstract: Disclosed is an extendable sunshade magnetically attached to the roof of a car, being characterized in that a roller box is used to contain two sunshade rollers so that extendable sunshades wound around the two rollers may be extended in opposite directions, that a support is connected to a bottom of the roller box, and a rubber plate receiving a plurality of magnets is connected to a bottom surface of the support, so that the roller box can be magnetically attached to the roof of a car. The disclosed extendable sunshade may be used to shield the metal roof and windshields of the car, or, alternatively, be used to cover the window glass panes of the car, depending on the shining direction of sun light, so that high temperature and oppressive heat accumulated in the car parking or moving under strong sun light may be largely lowered and the energy for air conditioning in the car can be effectively saved.
