Air Conditioning and Refrigeration Technology Air conditioning has rapidly grown over the past 50 years, from a luxury to a standard system includedin most residential and commercial buildings. In 1970, 36% of residences in the U.S. were ei...
车床是一种机床，它将工件绕轴旋转，完成各种各样的操作，如切割、打磨、滚花、钻孔或变形等，并将其应用到工件上，以创建一个具有对称的旋转轴的物体。 车床用于木工、金属加...
直流电机的特点是他们的多功用性。依靠不同的并励、串励和他励励磁绕组的组合，他们可以被设计为动态的和静态的运转方式从而呈现出宽广范围变化的伏安、－特性或速度－转矩特...
Relative humidity levels of an incubator were measured and controlled. An ultrasonic nebulizer system as an active humidier was used to humidify the incubator environment. An integrated circuit-type humidity sensor was used to measure the h...
Title:Fabrication and Structural Design of Micro Pressure Sensors for Tire Pressure Measurement Systems (TPMS) Abstract： In this paper we describe the design and testing of a micro piezoresistive pressure sensor for a Tire Pressure Measur...
ABSTRACT The purpose of this paper is to establish an effective inspection system by using OMM (On-Machine Measurement) system based PC-NC. This system can reduce manufacturing lead time because a workpiece is inspected at every machining p...
tudy of the technological parameters of ultrasonic nebulization ABSTRACT The principle of an ultrasonic nebulizer is based on the vibrations of a piezoelectric crystal driven by an alternating electrical field. These periodic vibrations are...
The liquid–solid mass transfer behavior of 8 cylindrical blade impeller it can act as electrode or catalyst support in a new stirred tank reactor was studied in relation to catalytic and electrochemical reactor...
The present paper treats the agitation of shear thinning fluids in a cylindrical unbaffled vessel with a flat-bottom. Two kinds of impellers have been used: simple and double helical ribbons. This work is achieved with the help of CFD packa...
Construction equipment such as tractors, cranes, and backhoes all use linkages ex- tensively in their design. Figure 1-1b shows a small backhoe that is a linkage driven by hydraulic cylinders. Another application using linkages is thatof ex...
