Abstract: A computer hard drive heat dissipation device for a fixed, swappable or externally connectable hard drive is provided. A heat socket is provided inside a metallic housing, and a heat board is provided on the bottom of the metallic housing. A contact surface where the heat socket and the heat board contact the hard drive, corresponding to a hard drive heat source, is provided with a high heat conductive material or a high heat conductive medium capable of absorbing vibration, enhancing quantitative fit, and conducting heat. The hard drive contact surface and its surrounding space are provided with vibration absorption and sound absorption materials respectively so as to obtain good capabilities in heat dissipation, vibration absorption and sound absorption.

Abstract: Provided with a switching power supply including a built-in chip set so as to control a built cooling fan and or an ambient cooling fan to operate even after the computer system is shut down. As such, the heat built-up within the computer system can be effectively dissipated so as to prolong the service life of the computer.

Abstract: This invention relates to a power supply capable of dissipating heat from computer unit, for enhancing the heat source heat-dissipating effect within the computer unit, including: a blower for exhausting air provided in or above the power supply. The blower is provided with an adjustment knob extended to and provided at an outside of the power supply or computer casing by means of wires. A power terminal of the blower is connected to a backup power of the power supply, where the backup power is controlled by a surrounding temperature monitoring device to operate the blower continuously after shutting off the computer until surrounding temperature has reached a target value.

Abstract: Disclosed is a rotational speed adjustment device or switch that is provided in a corner screw hole at a front or back of a heat dissipating fan frame, the rotational speed adjustment device or switch being electrically connected to a power source of the fan by means of a power cord or other conductive metals, the adjustment device or switch being extended with a knob that is individually exposed out of the fan frame, the heat dissipating fan may be installed in any space that requires heat dissipation or to an outer periphery of a unit casing, to allow a user to adjust rotational speed of the heat dissipating fan at one's desire at any time.

Abstract: A cooling fan with built-in adjustable speed structure of the invention is provided herein. The cooling fan of the invention fan has built-in fan speed controlling parts installed inside, in addition, has a fan speed controlling interface, such as a knob or a keystroke, positioned on the fan frame for a user to directly adjust fan speed as needed without additional wirings to be connected. The invention can be used at any environment where needs a cooling fan.

Abstract: A power supply provides direct current power supply to peripheral devices inside or outside of a computer main unit after the computer system is switched off, to solve the problem of the prior art wherein power is no longer supplied to the components in the computer or peripheral devices after the computer main unit is switched off.

Abstract: A device and method for measuring the jitters of phase locked loop signals. A phase lead or phase lag relationship between an input signal and an output signal of a phase locked loop is found. According to the phase relationship and using multiplexers, a first phase difference signal and a second phase difference signal are re-routed to a subtraction unit and produces a jitter-level output signal. The jitter-level output signal represents the absolute value of the difference of pulse width between the first phase difference signal and the second phase difference signal.

Abstract: The present invention provides a heat-dissipating fan with a manually adjustable speed-setting function by locating a speed-adjusting revolving-button or push-button in one of the bolt-holes of the front side or rear side of said heat-dissipating fan. The size, and structure of the regular original heat-dissipating fan is therefore unchanged and a speed-adjusting revolving-button or push-button is provided in a selected bolt-hole for users to set the speed of the fan directly according to needs at any time. Additionally, a temperature-detecting thermal resistor is included to achieve 2-fold speed-adjusting.

Abstract: The present invention provides a heat-dissipating fan with manually adjustable speed-setting function, particularly referring to using one of the bolt-holes of the front side or rear side of said heat-dissipating fan without the size, and structure of the regular original heat-dissipating fan changed, and providing a speed-adjusting revolving-button or push-button at that bolt-hole, for users to set the speed of the fan directly according to needs any time, and adapting with the original temperature-detecting thermal resistor to achieve, 2-fold, speed-adjusting.
