Abstract: The present invention relates to a drill bit structure which comprises a body. The body has a free end, an intermediate section and a connection end. The body comprises a first groove portion, a second groove portion, a third groove portion, a fourth groove portion and a fifth groove portion. The first groove portion is partially overlapped with the third groove portion from the free end. The second groove portion is partially overlapped with the fourth groove portion from the free end. After extending a preset axial distance from the free end, the first groove portion and the second groove portion are partially overlapped with each other by forming an intersecting protrusion. The fifth groove portion is extended from the intermediate section toward the connection end. The first, second, third and fourth groove portions are extended to the fifth groove portion.

Abstract: A LED-illuminated water spraying gun may include a spray gun, a cover body, a base, a LED light, a diversion piece, and a water cover. The base has a first chamber and a second chamber, and a through hole is formed between the first chamber and the second chamber, and the power generator of the LED light can be disposed inside the first chamber and a shaft of the power generator is protruding into the second chamber. A plurality rotating blades are connected to the shaft, and by rotating the blade with water flow, the power generator can further power the LED light. A diversion hole that is outside of first chamber of the base is connected to the second chamber and the water cover covers the base of the cover body. By rotating the water cover, different types of water spraying holes can be selected.

Abstract: An LED-illuminated water spraying gun may include a water spraying gun, a fixed sleeve, a nozzle, an illumination device and a movable sleeve, which the nozzle has assembly hole to set the LED lamp on, and set power generating device on holding chamber. It can let the power generating device's rotary disc on shaft can be rotated by water flow, and let the LED lamp can generate illumination at movable sleeve's guide ring, which movable sleeve's forth thread lock on nozzle's third thread, it makes water flow can flow through from nozzle's side hole to movable sleeve's through hole, and can adjust the hole to spray the water. The movable sleeve can move and make adjusting hole move between nozzle's ring part and tapered part, which can change the spray and the move will not influence the LED lamp.

Abstract: An operating panel of an uninterruptible power system (UPS) has multiple function buttons, a control module and an LCD display. Each of the function buttons is controlled to enter a main function when it has been pressed more than a threshold time or to perform a first action when it has been pressed less than the threshold time. The control module is connected to the multiple function buttons to determine whether any of the function buttons has been pressed more than the threshold time. The LCD display is connected to the control module to show operating information. A user of the UPS can directly choose a main function by long pressing the corresponding function button, and then further select to a particular sub-function by shortly clicking the function buttons.

Abstract: A diindenothiophene derivative of the following formula (1) is disclosed: wherein each of G1, G2, G3 and G4 is independently an unsubstituted or substituted C6-C40-aromatic group or a C1-C40-aliphatic group; A is an electron-withdrawing group; and D is an electron-donating group. The inventive diindenothiophene derivatives can be used in a dye-sensitized solar cell.
