Abstract: PURPOSE: To prevent a measurement error and a classification error by providing, for an automatic handler, a detection means for detecting the presence of an electronic component 2 after measurement in a carrier 5 and thereby determining whether or not the electronic component 2 sticks to a pusher 6. CONSTITUTION: A detector 3 comprising a projector 3A and a light receiver 3B is disposed between a measurement part 4C and a drying chamber 4D. When the carrier 5 is conveyed to the drying chamber 4D and passes the detector 3 after the measurement, light is projected to the receiving position of each electronic component 2 in the carrier 5 from the projector 3A, and the projected light is detected by the photodetector 3B. When the light is detected, the electronic component 2 is not present at the receiving position, the electronic component 2 is judged to be sticking to the pusher 6 and hence, the automatic handler is stopped.

Title: Method and apparatus for reducing dissipation rate of fluid ejected into boundary layer
IPC: F42B19/12
Filed: 1999-12-30
Abstract: Skin friction reduction on a surface moving relative to a fluid can be obtained by ejecting a polymer-water mixture/solution into the boundary layer. The efficacy of the ejected polymer-water mixture/solution is closely related to polymer dissipation out of the boundary layer and conditioning (i.e, lengthening, unwinding or stretching) of the polymer molecules by liquid shear forces immediately before ejection. The invention is a method and apparatus for conditioning and ejecting a polymer-water mixture/solution that improves drag reduction characteristics of the mixture/solution and maintains the mixture/solution in the boundary layer for as long as possible. By improving the drag-reduction characteristics of the polymer-water mixture/solution and by extending the time it remains in the near-wall region, the ejector can increase the performance and reduce the volume and storage requirements of a drag-reduction system. Although this invention was intended for polymer-water mixture/solution ejection, it can be used for ejection of any substance into a flowing fluid.

Abstract: PURPOSE: An external loop power control apparatus and method in a mobile communication system are provided to increase a power control efficiency by differentially setting a target energy-to-noise ratio in a general mode and in an adjustment mode depending on a channel situation. CONSTITUTION: A controller receives a CRC(Cyclic Redundancy Check)-checked data(211). The controller checks whether there is a frame error in the CRC-checked data. If there is a frame error, the controller increases a target energy-to-noise ratio(Eb/No) for an external loop power control as high as an increase unit level(up_step)(215). If there is no error in the frame, the controller reduces the target energy-to-noise ratio as low as a reduction unit level(down_step)(217). The controller checks whether a row BER value measured for a currently received frame is greater than a pre-set threshold raw BER value(219). If the raw BER value is grater than the threshold raw BER value(221), the controller switches an external loop power control mode of a user terminal from a normal mode to an adjustment mode(221).
