Abstract: A time sequence control circuit is provided to control time sequence of a motherboard of a computer. A first voltage received by a power supply receiving terminal is greater than a preset voltage before a signal control terminal on the motherboard receives a second voltage during turning on the computer. During shutting off the computer, the first voltage at the power supply receiving terminal drops and is less than the preset voltage, and the second voltage supplied to the signal control terminal on the motherboard is shut off.

Abstract: A magnet band includes: a flexible band body formed with pockets and through-holes; magnetic elements respectively retained in the pockets of the band body; a pair of belts, each of which has a connecting end portion; and a pair of connectors, each of which includes a pair of tabs secured to the connecting end portion of a respective one of the belts, and each of which is provided with at least one first interlocking member on one of the tabs, and at least one second interlocking member on the other of the tabs. The tabs of each of the connectors are connected to the band body in such a manner that that the first interlocking member on one of the tabs extends through a selected one of the through-holes to interlock the second interlocking member on the other of the tabs.
