Hydraulic valve driving device and engine including the same and vehicle

InactiveUS20060157010A1Quick and improved engine startingWeaken energyEngine controllersMachines/enginesValve actuatorHydraulic pump
A hydraulic valve driving device includes a valve actuator operable to drive an engine valve, a hydraulic pump that generates the oil pressure for the valve actuator, a hydraulic pump driving motor that drives the hydraulic pump, and a starter motor. At the time of engine starting, after the hydraulic pump is driven by the hydraulic pump driving motor while the crank is stopped in the first engine-starting mode, and then the crank and the hydraulic pump are driven by the starter motor in the second engine-starting mode.

Safe operation method of active voltage reduction for ground fault phase of non-effective grounding system

The invention discloses a safe operation method of active voltage reduction for a ground fault phase of a non-effective grounding system, and the safe operation method is applied to the ground fault safe operation of a neutral point non-effective grounding generator or power distribution network. When a single-phase ground fault occurs, an adjustable current source is applied additionally between a bus at a non-effective grounding system side and the ground, or between a circuit and the ground, or between a neutral point and the ground, or between a shunting tap at a transformer non-effective grounding system side winding and the ground, to adjust the injected current magnitude and phase and further reduce the fault phase voltage, so that the fault point voltage is lower than the ground arc continuous combustion voltage to meet the long-term non-stop safe operation requirement. According to the invention, the fault phase voltage is reduced to a non-zero safe operation value, so the permanent single-phase earth fault current is suppressed, the rising amplitude of the non-fault phase voltage is limited, the risk of non-fault phase insulation breakdown is reduced, the personal safety and equipment security risks are reduced, the occurrence of power outages is effectively prevented, and power supply reliability and security are greatly improved.

Provided is an illumination device capable of preventing a reflection sheet in the periphery of a light-emitting element from being raised while minimizing the instability in the fixture of a diffusion lens. The illumination device comprises a light-emitting element, a mounting substrate, a diffusion lens, and a reflection sheet having a through-hole. The diffusing lens includes a lens portion for diffusing light, and a fixed portion to be fixed to the mounting substrate. An engaging portion that sandwiches the reflection sheet between the engaging portion and the mounting substrate is formed in the fixed portion.

Cold-accumulation type refrigerant and cold-accumulation type cold compress bag

InactiveCN102660232AIncrease heat of solutionFormation does not affectHeat-exchange elementsTherapeutic coolingPotassium nitrateCommon cold
The invention discloses a cold-accumulation type refrigerant and a cold-accumulation type cold compress bag. The refrigerant comprises the following components in percentage by weight: 30-40% of urea, 6-12% of ammonium chloride, 6-12% of potassium nitrate, 2-5% of guar and 35-45% of water. The cold compress bag comprises an outer bag, wherein solid materials comprising the refrigerant and water are arranged in the outer bag, and a sealing strip is arranged in the outer bag to separate the solid materials from the water. The refrigerant disclosed by the invention comprises three refrigerants, the solution heat of the cold compress bag is increased by various refrigerants, and the cold compress effect is better. Because the macromolecule edible-grade guar gum is added in refrigerant particles, the cold compress time of the cold-accumulation type cold compress bag disclosed by the invention is 2-3 times longer than the traditional common cold-accumulation type cold compress bag, so that the whole system is in a colloid shape and is unlikely to flow, and the use comfort level of a patient is improved. The solid materials and the water are separated by the sealing strip, and the cold compress bag is convenient to use; and in the transportation process, the solid materials and the water can be effectively separated and cannot be mixed, which is convenient for transporting the cold compress bag.
