Abstract: Disclosed by the present invention are an aqueous polyurethane functional mask substrate and an application thereof. Two kinds of water-based polyurethane dispersions are used as the main components of the mask substrate. The transdermal penetration and absorption of functional ingredients such as whitening, moisturizing and anti-aging ingredients in facial mask products are promoted by means of the special cross-linked structures of polyurethane films. During use, a mask is evenly applied to the face; and after the mask dries, the entire mask may be removed directly or removed after being moistened using water. The mask substrate according to the present invention is also applicable to body masks such as a hand mask, a neck mask and a back mask.

Abstract: The invention discloses a method for producing a carbon composite material, which includes the step of providing at least one carbon nanostructured composite material onto the surface of LiFePO4 particles to produce a LiFePO4/carbon nanostructured composite material. The carbon nanostructured composite material is obtained by synthesizing at least one nanostructured composite material to form the carbon nanostructured composite material.

Abstract: The present invention relates to a table saw having a stationary worktable having a work surface, a base for supporting the worktable, a motor-driven cutting device mounted between the worktable and base and at least one auxiliary support device disposed beside the worktable. The auxiliary support device is pivotal relative to the stationary table and the auxiliary support device can be converted between a extended position and a folded position. The auxiliary support device pivots upwardly when it converts from the extended position to the folded position and provides adequate support for making accurate cuts and is convenient to store or transport.

Abstract: The present invention discloses a portable phone using a sound receiving unit installed in the portable phone to receive a sound in the surrounding within an appropriate range, and then using a sound source playback device to play a sound after being amplified, so that a person having a hearing problem can just carry a mobile phone to concurrently have the basic functions of the mobile phone and use the sound amplification function of the mobile phone to supplement the deficiency of the hearing ability when talking to or communicating with others. The portable phone can be toggled between the regular telephone function and the hearing aid function, and thus concurrently serving as a hearing aid to the people who have a hearing problem.

Abstract: A contact is mounted in a battery connector of an electronic device and has a soldering section, a body section, a resilient section, two inclined gaps and a contacting section. The body section extends from the soldering section and has a first end and a second end. The resilient section extends from the body section and has a first end, a second end and a tapered segment. The first end of the resilient section is connected to the second end of the body section. The tapered segment is tapered toward the first end of the resilient section. The inclined gaps are defined in the second end of the body section to form the tapered segment. The contacting segment extends from the second end of the resilient section. With the inclined gaps, the contact is compact, resilient and has a low material cost.

Abstract: A SIM card connector includes an insulative base including on its either side an L-shaped rear groove, a recess including a rear ramp, an intermediate protrusion, a tab between the rear ramp and the protrusion, and a front protuberance, and a front stop member; a cover including two side flanges each including a rear pin slidably fitted in and confined by the groove to form a pivot, rear and front gables, and an intermediate tongue; and conductors on a bottom of the base. Sliding the cover forward will interlock the cover and the base by moving either pin to a forward end of the groove with either rear fastening member being urged against the protuberance, either tongue being stopped by the protrusion, and either front fastening member being securely engaged with both the stop member and protuberance after passing the stop member.
