6252.全球汽车挺杆市场报告（2015-2019年）
[汽车制造业] [2015-10-31]
The tappet, also called a cam follower or valve lifter, is a component that runs on the camshaft, and is made to move vertically by the action of a rotating cam. It is a small part interposed between each camshaft lobe for the valve-lifting mechanism, which raises the valve off the seat. The side valves lift upward where the overhead valves are depressed to lift or open the side valves, and vice versa. As a camshaft rotates, each lobe produces both a vertical and a side thrust. In an overhead valve engine, the tappet is used low down in the engine block. From there, it drives a long thin pushrod up to the top of the engine, above the cylinder head.

6253.全球氮化镓半导体设备市场报告（2015-2019年）
[计算机、通信和其他电子设备制造业,仪器仪表制造业] [2015-10-31]
GaN is a wide bandgap semiconductor material that has emerged as a prominent solution to the drawbacks of its traditional counterpart, silicon, especially in power electronics. A wide bandgap allows a larger flow of energy to move electrons in GaN than in silicon. Silicon has always been the preferred choice for computing and electronic devices since its invention, almost 50 years ago.

6257.全球割灌机市场报告（2015-2019年）
[电气机械和器材制造业,农、林、牧、渔业,专用设备制造业] [2015-10-31]
Garden equipment like brush cutters and power lawn mowers help in mowing, cutting, irrigating, and fertilizing the garden to provide a healthy, dense, and high-quality lawn. Innovations in technology have led to the creation of battery-powered brush cutters and lightweight gardening equipment, generating gardening interests among people. Brush cutters are of two types, namely gas brush cutters and electric brush cutters. The demand for electric brush cutters is increasing worldwide, since they are easy to use, lightweight, eco-friendly, and less noisy than gas brush cutters.

6260.全球清洁工作台市场报告（2015-2019年）
[专用设备制造业,仪器仪表制造业] [2015-10-31]
Clean benches prevent particle contamination of a workspace and the materials on it by filtering the air around it. They use a high-efficiency particulate arrestance (HEPA) filter to blow air toward the user at constant speeds. A typical clean bench consists of a working space, which is similar to a bench or a table, and air blowing and suction ports. People who work with non-hazardous resources that require clean, particle-free air are the major end-users of clean benches.
