摘要： A method for measuring the viscosity of a green compact sample includes the steps of finding a corrected value V′ of the sample volume of the green compact sample, where the corrected value V′ of the sample volume is a volume occupied by the inorganic powder in the green compact sample; finding a corrected value (dh/dt)′ of the sample deformation rate of the green compact sample, where the corrected value (dh/dt)′ of the sample deformation rate is the difference between the apparent sample deformation rate and the sample deformation rate due to sintering shrinkage; separating a temperature range X in which sintering shrinkage dominates and a temperature range Y in which plastic deformation dominates with respect to the displacement of the green compact sample; substituting the corrected value V′ of the sample volume for the sample volume V and substituting the corrected value (dh/dt)′ of the sample deformation rate for the sample deformation rate dh/dt in the Gent equation with respect to the temperature range X; and substituting the corrected value V′ of the sample volume for the sample volume V in the Gent equation with respect to the temperature range Y.

摘要： A capillary test specimen, method, and system for visualizing and quantifying capillary flow of liquids under realistic conditions, including polymer underfilling, injection molding, soldering, brazing, and casting. The capillary test specimen simulates complex joint geometries and has an open cross-section to permit easy visual access from the side. A high-speed, high-magnification camera system records the location and shape of the moving liquid front in real-time, in-situ as it flows out of a source cavity, through an open capillary channel between two surfaces having a controlled capillary gap, and into an open fillet cavity, where it subsequently forms a fillet on free surfaces that have been configured to simulate realistic joint geometries. Electric resistance heating rapidly heats the test specimen, without using a furnace. Image-processing software analyzes the recorded images and calculates the velocity of the moving liquid front, fillet contact angles, and shape of the fillet's meniscus, among other parameters.

摘要： It is intended to perform optimum autofocusing and autoleveling control in a scanning exposure apparatus. A focus position &Dgr;Z (focus position of a curved surface 46 or 47) in a region 34 surrounding a slit exposure region 16A or 16 is measured on the exposure plane of a wafer. For the narrow exposure region 16A, an approximate plane of a partial curved surface 46a in the exposure region 16A is calculated by using only data on the focus position of the partial curved surface 46a. For the normal exposure region 16, an approximate plane of a partial curved surface 47a in the exposure region 16 is calculated by using only data on the focus position of the partial curved surface 47a. These approximate planes are matched with an imaging plane by an optical projection system. A curved surface 51 is obtained by filtering the curved surface 50 in the region 34 with a low-pass filter which has an amplitude transmission characteristic ¦H(j&ohgr;)¦ on a spatial frequency range. The average plane of the curved surface 51 is matched with the imaging plane of the optical projection system. Cutoff spatial frequencies &ohgr;X and &ohgr;Y of the low-pass filter are set to values inversely proportional to the width WO of the exposure region 16 in the scanning direction and the height HO in the nonscanning direction.

摘要： There is provided a double-headed mass sensor (25) in which between a first connecting plate (22A) joined to a first diaphragm (21A) at respective sides and a second connecting plate (22B) joined to a second diaphragm (21B) at respective sides, a first sensing plate (41A), on which a main element (44) is provided on at least one plane surface, is bridged, and a resonating portion comprising the diaphragms (21A), (21B), the connecting plates (22A), (22B), the first sensing plate (41A) and the main element (44) is joined to a sensor substrate (27). Change in the mass of each of the diaphragms (21A), (21B) is measured by measuring change in the resonant frequency of the resonating portion accompanying the change in the mass of the diaphragms (21A), (21B). The mass sensor of the present invention enables the easy and highly accurate measurement of a minute mass of a nanogram order including microorganisms such as bacteria and viruses, chemical substances, and the thickness of vapor-deposited films.

摘要： A meter for measuring the volume of a flowing fluid includes a viscosensitive unit through which the fluid flows under laminar flow conditions, a first fluidic oscillator in series with the viscosensitive unit, and a second fluidic oscillator shunting at least the viscosensitive unit. The viscosensitive unit and the fluidic oscillators are adapted to determine the viscosity of the fluid so as to apply to the fluid volume measured by the fluidic oscillators a correction dependent on the Reynolds number.

摘要： A sampling apparatus is characterized by a sampler operable to obtain samples of liquid product from a body of product in a vessel. The sampler includes a plunger having a sample receiving recess and a connecting device couples the sampler to the vessel at an aperture to the vessel. The sampler is attached to the connecting device and the connecting device is moveable between a first position placing the sampler into, and a second position taking the sampler out of, communication with the aperture. With the connecting device in the first position, the plunger is reciprocated to extend the plunger and its recess through the connecting device and vessel aperture into product in the vessel to receive a product sample in the recess. The plunger is then retracted from the vessel and through the connecting device to deliver the product sample to a collection point. During reciprocation of the plunger, a liquid seal is maintained between the vessel interior and sample collection point, and when the connecting device is moved to the second position, the sampler can be detached from the connecting device for service or repair, without escape of liquid from the vessel through the connecting device. Advantageously, the sampler remains stationary during movement of the connecting device between the first and second positions, so that additional space in which to accommodate movement of the sampler is not required when attaching the sampler and connecting device to the vessel.
