Abstract: Method of controlling warning lights to enter low power mode includes steps of: setting predetermined ID Number of warning lights as starter, and remaining ID numbers as receivers; warning light set as starter receiving start command from control bus through signal line, and sending data, clock pulse, and ID information from data bus, and choosing low power mode to flash; warning lights set as receivers obtaining data, clock pulse, and ID information from data bus through signal lines, and flash mode of receivers and starter flashing in low power mode, and active switch of control circuit that executes low power mode receiving low power command sent from starter and forming conductive state, and current-reducing resistor which is electrically connected to active switch reducing passing current to predetermined ratio, so that reduced current is transmitted to receivers and then starter executes low power mode and reduces brightness of warning lights.

Abstract: A warning light control method includes the steps of: accepting multiple warning lights to receive a start command to set up Flash Mode and numbering each warning light sequentially starting from 1, and using Flash Mode number to synchronously set ID Number of each warning light; setting the ID Number of a predetermined warning light as Starter and the remaining ID Numbers as Receivers; the warning light of Starter receiving Start Command from Control Bus through cable, and sending Data, Clock Pulse and ID Information from Data Bus, and selecting one for flashing by Flash Mode; warning lights of Receivers get Data, Clock Pulse and ID Information from Data Bus through cables thereof, and warning lights of Receivers and Starter are flashing synchronously or asynchronously; whether Control Bus of Starter and Receivers has received Change ID Command.

Abstract: A reset mechanism for an electronic throttle body comprising a valve, a throttle shaft, a reset gear, an upper spring seat, a lower spring seat, and a reset spring. A support leg is installed in the reset gear. The upper spring seat, the reset spring, and the lower spring seat are sleeved outside the reset gear. Two ends of the reset spring are fixed to the upper spring seat and the lower spring seat, respectively. The upper spring seat has an upper support leg surface attached to a first side of a valve limiting block and a side of the support leg. The lower spring seat has a lower support leg surface attached to a second side of the valve limiting block and another side of the support leg.

Abstract: A micro-bubble generator has an intake manifold, a casing threadingly connected to the intake manifold, a first air inlet channel defined between threads of the intake manifold and the casing, a booster located inside the casing and having a gap defined between the casing and the booster to form a second air inlet channel and to communicate with the first air inlet channel, a bubble generating tube located inside the casing and having a third air inlet channel defined between the end faces of the bubble generating tube and of the booster. The booster includes a first water inlet and a first water outlet having an inner diameter smaller than that of the first water inlet so that water velocity at the first water outlet is faster than that at the first water inlet, which forces ambient air to enter the bubble generating tube via air inlet channels and to be mixed with water in the bubble generating tube to generate bubbles.

Abstract: A chain assembly includes interconnected chain units each having two rollers, two bushings disposed through the rollers, two inner plates rotationally disposed on the bushings, and two pins penetrating the bushings and the inner plates. Two outer plates are rotationally fixed to respective pins between adjacent inner plates. Each inner plate has two inner pin holes, two rims projecting from one surface of the inner plate, and a contact area formed around the rims. Each outer plate has two outer pin holes, two accommodation portions protruding from one surface of the outer plate to provide two rooms formed into opposing surface thereof, and a positioning area formed around the rooms for fitting snugly with adjacent contact areas when the respective rims are completely covered by the rooms. Therefore, the structure strength is increased, the transmission is stable and smooth, and no entry and accumulation of dust is incurred.

Abstract: A leaf chain includes a plurality of chain units each having two pins, around which first and second alternate inner plates between outer plates are mounted. The plates form respective apertures where the pins penetrate. Each chain unit has bushings located in the apertures of the first and second inner plates, and first washers disposed between any two adjacent bushings and between the bushings and the outer plates. There are connecting plates located at an outer side of the outer plates and tightly engaged with the pins to prevent the outer plates from being deformed because of a concentration of large force in the outer plates during the transmission. The outer plates have a loose engagement with the pins to prevent the pins and inner plates from being worn away. The first washers help the sealing effect to maintain the preferable stability and transmissibility and prolong the operating life.

Abstract: A conveying chain comprises a plurality of chain sets connected together, each chain set comprises a chain bush, inner plates and outer plates respectively disposed on both sides of the chain bush, and a pin member penetrating the chain bush and connecting the inner and the outer plates, wherein a plurality of openings are defined at intervals on a circumference of the chain bush. A through hole is communicated with an outside via the openings, so that dust or exterior impurities accumulated between the chain bush and the pin member can be outwardly discharged through the openings to prevent the accumulation of the dust or impurities from having an adverse influence on the transmission of the chain and to increase the smoothness of the chain operation and the use duration efficiently.

Abstract: A leaf chain comprises a plurality of links connected together, each of which includes two aligned rollers, at least one first inner plate provided with apertures to pivotally receive the rollers, and two outer plates fixed to the respective rollers and respectively positioned at external sides of the first inner plate. Wherein, two spacers are respectively disposed at both peripheries of the aperture on the first inner plate and annularly disposed on the rollers so as to block a leakage of a lubricant distributed over an interstice formed between each roller and each aperture.

Abstract: A cradle for a hand-held tool for machining of cylinder head valve guide holes. The tooling has a pilot portion. A collar has a passage for the tooling and is shaped to engage a least worn portion of a valve seat associated with the valve guide hole around the circumference thereof without engaging more worn portions of the valve seat. The cradle comprises a bracket which has a passage for the tooling without passage of the collar so that the bracket can bear on the collar. Force is applied to the bracket to hold the collar in engagement with the valve seat.
