摘要： A bicycle real wheel hub includes pulling spokes and static spokes connected to the disks thereof. The hub includes a tubular portion with two disks respectively connected to two ends of the tubular portion. Multiple protrusions protrude from the inner side of each disk. The head of each pulling spoke is secured to the protrusion corresponding thereto. The head of each static spoke is secured to the disks. The heads of the pulling spokes are located closer to the middle point of the tubular portion than the heads of the static spokes. When the hub rotates, the static spokes provide strength in the axial direction of the hub, and the pulling spokes have strong tension so that the hub bears higher torque.

摘要： A temperature controlling system adapted for a projection apparatus is provided. The projection apparatus comprises at least a heat generating element, while the temperature controlling system comprises a liquid flow system, a heat generating device, and a heat transferring device. The liquid flow system is disposed along the heat generating element. The heat generating device produces heat with a positive value (endothermic) or a negative value (exothermic) in response to an environment dependent on the location of the projection apparatus. The heat transferring device transfers the heat generated by the heat generating device along the liquid flow system. The present invention maintains the operation of the projection apparatus under the desired working temperature and enables a thermal equilibrium of the projection apparatus without being influenced by the over-temperature or under-temperature of the external environment.

摘要： An active continuous DC power supply insulation malfunction detection circuit includes a leakage current detection unit, a positive voltage terminal compensation unit and a negative voltage terminal compensation unit respectively at a positive voltage terminal and a negative voltage terminal of the power supply system. The positive and negative voltage terminal compensation units include respectively a one-way discharger and a power source unit that are forward conducted. The invention can improve the shortcoming of the conventional detection techniques that use passive elements for detecting ground insulation deterioration by letting the power source unit discharge through the one-way discharger so that the leakage current detection unit can continuously detect and measure current variations passing through the positive and negative voltage terminals without interruption, and thereby easily obtain leakage current value and provide active and continuous detection of ground insulation deterioration.

摘要： A cooling module for use with a DMD module of a projection apparatus is provided. The cooling module comprises a heat conduction device, at least one heat pipe, and at least one fin. Heat accumulating on the DMD module can be released from the heat conduction device to the fins through the heat pipe. Meanwhile, the fins partially overlap along the direction of the light coming from the light source.

摘要： An electronic apparatus includes a casing, a light source housed in the casing, and a heat dissipation device positioned between the casing and the light source. The casing is formed with a lead angle on its corner to create an inclined surface. The heat dissipation device has a first and a second end surfaces opposite to each other and a sidewall connected between them. The sidewall of the fan frame neighbors the inclined surface and has a slanting direction substantially paralleled to the inclined surface.
