Abstract: A notebook computer having a temperature adjustment function for a microprocessor includes a clock generator, a thermal sensor, an I/O controller, a bus switch, and a voltage regulator. The thermal sensor and the I/O controller are connected between the microprocessor and the clock generator. The bus switch is connected between the microprocessor and the I/O controller and with the voltage regulator. When the surface temperature of the microprocessor exceeds a predetermined temperature, the system BIOS will immediately issue a command to the I/O controller to automatically lower the external clock and the power source voltage level of the microprocessor. Thereby, the power consumption of the microprocessor can be reduced to lower the surface temperature.

Abstract: A computer remotely controlled turned on or off by a remote controller is provided. The computer includes a receiver, a microprocessor, a power source management module, an I/O controller, a universal output device, and an audio player. The receiver receives a signal from the remote controller. The microprocessor executes a corresponding command according to a frequency of the signal by a pre-configured frequency spectrum table. The I/O controller controls the power source management module according to the command executed by the microprocessor. Thereby, the remote controller can remotely turning on or off the computer, and can perform some specific functions to make the computer much more functionally similar to, the electric appliance.

Abstract: A hairclip includes two clip members and a connecting rod. Each clip member includes an engaging portion extending along a longitudinal direction thereof. The engaging portions are aligned with each other for pivotal connection, each engaging portion having an engaging hole. The twistable connecting rod has two ends respectively, securely fixed in the engaging holes of the clip members such that an intermediate portion of the connecting rod is twisted when the clip members are pivoted relative to each other and that the twisted intermediate portion of the connecting rod resumes its shape after the clip members are released.
Abstract: A hair holding device includes a number of first plates and a corresponding number of second plates arranged in an annular manner. Each first plate is engaged with three second plates, and each second plate engages with three first plates. At least one of the second plates includes an extension formed on a lateral side thereof, the extension having an engaging member formed thereon. At least one of the first plates includes a slot for releasably engaging with the engaging member and allowing the engaging member to slide in the slot.
Abstract: A hair holder includes two symmetric holder members made of flexible material. Each holder member includes a first portion for holding hair, a second portion for retaining hair, and a transition portion interconnecting the first portion and the second portion in an acute angle to thereby define a hair holding space therebetween. The first portion of each holder member includes a number of first slits spaced along a width thereof to thereby define a number of first teeth spaced along the width. The second portion of each holder member includes a number of second slits spaced along a width thereof to thereby define a number of second teeth spaced along the width. The width of each second tooth increases from a distal end of the second portion to the transition portion, thereby defining an engaging portion adjacent to the transition portion.
Abstract: A hair holding device includes a number of first plates and a corresponding number of second plates arranged in an annular manner. Each first plate is engaged with three second plates, and each second plate engages with three first plates. Each second plate includes a fastening member formed on a first lateral side thereof and an engaging member formed on a second lateral side thereof such that the engaging member of each second plate may releasably receive the fastening member of an adjacent second plate. The engaging member includes two flexible pieces projected from the second side of the second plate and having a receiving compartment therebetween. Each flexible piece has an engaging tooth formed on a side thereof that faces the other flexible piece. In addition, the fastening member includes a number of teeth on each of two sides thereof so as to be selectively engaged with the engaging teeth of the flexible pieces.
Abstract: A hair clip includes a body, a decorative plate changeably fitting in a shallow recess on an upper surface of the body, and a conventional metal clip assembled together. The body has posts to fit in post holes of the metal clip to combine the both together. The decorative plate has projections to engage holes in the body so as to enable the decorative plate easily released for changing it with different colors and designs.
Abstract: A hair clip is provided which comprises a pair of clipping elements combined together by pins received within pin holes respectively formed in connecting protrusions. Furthermore, snap holders are provided on the outward side of the clipping elements to retain two snap ends of two elastic rings having great resilience, to enable the clipping elements to clip hair tightly.
Abstract: A spring fixing structure for a hairgrip includes a pin having an oval head and a plurality of annular projections in an intermediate portion engaging a wound coiled portion of a spring forcibly interposed between two ears of two hairgrip bodies after the pin is inserted through a center hole of the spring and of the two ears, and thus the pin, the spring and the two hairgrip bodies may be combined pivotally and stably together.
