Abstract:
Embodiments of the invention relate to an injector (1 1 ) for injecting a gas in a processing chamber, comprising an inlet (21 ) for receiving a gas wave or a gas flow, a flow-shaping section (20) for expanding the gas in a direction (ΥΥ') perpendicular to a propagation axis (XX') of the gas, and an outlet (22) for expelling the gas. The flow-shaping section has first and second sidewalls (23) which diverge according to a divergence angle (A1 ) relative to the propagation axis of the gas, and comprises means for slowing down the velocity of the gas near the center of the flow-shaping section, relative to the velocity of the gas near at least one sidewall.

Pressure compensators (1) for stabilizing a flow of water are disclosed. The pressure compensator (1) includes water compensating channels (3) formed on the outer periphery of their body (2), and flow orifices (4) passing through the pressure compensator (1), so that the water compensating channels and the flow orifices control the flow rate of the water at varying pressures. The body of the pressure compensator (1) preferably comprises a flexible material, such as rubber.
Abstract:
The present invention relates to an apparatus for jetting compressed air, comprising: an air inlet pipe having a circular or multiple-sided outer surface with an outlet hole for discharging compressed air introduced from an external source; and amplifying means having an inlet portion and an outlet portion, wherein said inlet portion has a contact surface which is circular or multiple-sided in correspondence to the shape of the outer surface of the air inlet pipe to be brought into contact with the outer surface of the air inlet pipe, and which has an inlet hole corresponding to the outlet hole of the air inlet pipe, and wherein said outlet portion amplifies the compressed air introduced through the inlet hole of the contact surface, and discharges the amplified air. The present invention also provides a method for manufacturing the apparatus. According to the disclosed apparatus for jetting compressed air and method for manufacturing same, the contact surface of the amplifying means is circular or multiple-sided in correspondence to the shape of the outer surface of the air inlet pipe, and therefore, the contact surface of the amplifying means and the outer surface of the air inlet pipe can be joined together in a tight and uniform manner. As a result, compressed air introduced to the amplifying means via the air inlet pipe can uniformly flow, and the compressed air can be prevented from leaking to the outside, thus increasing the jetting efficiency of the compressed air discharged through the amplifying means, and at the same time, ambient air can be discharged along the direction of discharging the compressed air, thus discharging a large volume of air in a single moment.
Abstract:
The invention is directed to a multilayer microfluidic probe (MFP) head (100). The head typically comprises a first (110) and second (120) layers facing each others, and at least one tubing port (182), extending from the first layer (110). The first layer comprises one or more via (112), whereby fluid communication is enabled through the first layer towards the second layer. The second layer comprises at least one microchannel (124), relaying fluid communication to an aperture (122). Such a multilayered MFP head is easier to fabricate than heads made with unitary construction. In particular, a microchannel can advantageously be engraved a groove (124) at the level of the interface between the two layers. The MFP head can further be interfaced with tubing using e.g. a standard fitting for tubing port. The invention has substantial potential for e.g. patterning continuous and discontinuous patterns of biomolecules on surfaces as well as for direct processing of resist materials in a non- contact mode.

본 발명은, 외부에서 유입된 압축공기가 유출되는 유출홀이 곡면형 또는 다면형의 외표면에 형성된 공기유입관, 및 상기 외표면의 형상에 대응되는 곡면형 또는 다면형을 가짐에 따라 상기 외표면과 접하도록 결합되는 접촉면을 가지며 상기 유출홀에 대응되는 유입홀이 상기 접촉면 상에 형성된 유입부와, 상기 접촉면의 유입홀을 통해 유입된 압축공기를 증폭하여 배출하는 배출부를 구비하는 증폭수단을 포함하는 압축공기 분사장치 및 그 제조방법을 제공한다. 개시된 압축공기 분사장치 및 그 제조방법에 따르면, 증폭수단의 접촉면의 형상을 공기유입관의 외표면 형상에 대응되도록 곡면형 또는 다면형으로 형성함에 따라, 증폭수단의 접촉면과 공기유입관의 외표면 사이를 긴밀하고 균일하게 접합 가능하다. 이에 따라, 공기유입관을 경유하여 증폭수단으로 유입되는 압축공기의 유동을 균일하게 할 수 있고, 압축공기가 외부로 유실되는 현상을 방지할 수 있어, 증폭수단을 통해 배출되는 압축공기의 분사효율을 증대시킴과 동시에, 주변에 있는 공기까지 배출방향에 대해 함께 배출함에 따라 다량의 공기를 순간적으로 내보낼 수 있는 이점이 있다.

Abstract:
A heated fluid injection string (106) injects heated treatment fluid into a well (102) in a subterranean zone (112) and generates an acoustic signal. An acoustic detector (212) detects the acoustic signal, and an acoustic signal analyzer (214) interprets the detected acoustic signal. In some implementations, the acoustic signal analyzer (214) interprets the detected acoustic signal to determine information about at least one of the heated fluid injection string (106), the well (102), or the subterranean zone (112).
