An apparatus and method for delivering repetitive, precision, low volume liquid dispensing from a dispensing orifice of a non-contact liquid dispensing apparatus. An elongated communication passageway of the dispensing apparatus is defined by interior walls having one end in fluid communication with a system fluid reservoir and an opposite end terminating at the dispensing orifice. A system fluid is placed in the communication passageway extending substantially continuously from the system fluid reservoir to the dispensing orifice. A relatively small volume of gaseous fluid is aspirated through the dispensing orifice, and into the communication passageway in a manner such that the gaseous fluid extends substantially continuously across the transverse cross-sectional dimension of the communication passageway. Subsequently, a dispensing liquid is aspirated through the dispensing orifice and into the communication passageway in a manner such that the relatively small volume of aspirated gaseous fluid forms a minute, unitary air gap fully enclosed between the interior walls of the communication passageway and a liquid interface between the system fluid and the dispensing liquid contained in the communication passageway. This minute air gap substantially prevents dispersion and dilution therebetween at the liquid interface. To effect dispensing, a rapid pressure pulse with a predetermined pulse width is applied to the system fluid upstream from the minute air gap, causing the pressure pulse to traverse the minute air gap to the dispensing liquid without substantial fluid compression of the minute air gap. This enables substantially accurate, relatively small volume, non-contact liquid dispensing of the dispensing liquid from the dispensing orifice.

The present invention relates to a high frequency module board device having a high frequency transmitting and receiving circuit for modulating and demodulating a high frequency signal. The high frequency module board device comprises a base board (2) whose main surface is formed as a build-up surface (2a) and a high frequency circuit part (3) formed on the build-up surface of the base board (2) and having passive elements formed. The base board (2) has an area (29) in which wiring is not formed in a lower layer from a fourth wiring layer (8b). The high frequency circuit part (3) has an upper electrode part (36) and a lower electrode part (35) in positions corresponding to the area (29) in which the wiring is not formed. Thus, since a capacitance (18) is provided just above the area (29) in which the wiring is not formed, a parasitic capacity that the capacitance (18) receives from ground patterns (14) is reduced. Accordingly, the characteristics of the capacitance (18) can be improved.

A leadless ceramic chip carrier useful in surface mounting of SAW devices includes electrically conductive vias and metalization between input and output bond pads for improved crosstalk suppression between input and output device connections. A protrusion extending from a top layer of a multilayer ceramic carrier provides additional electrical contact to a package seal brazed thereto. The vias are positioned between input and output bond pads and connect the metalized protrusion to package ground pads through contact with multiple metalized layers of the package for enhancing the electrical connection between the package Kovar seal ring and customer accessed ground pads. For further suppression of crosstalk, bond pads within the package for connection to the SAW device are spaced at a greater distance from each other than their corresponding pads on the package bottom surface thus maintaining an optimum spacing for package connection to printed circuit board pads for minimizing thermal mismatch effects.

Methods and apparatus for efficient transmission of data by half-duplex transceivers in satellite communication systems are provided. Time reference for the return link is skewed or time-lagged relative to the time reference for the forward link to reduce the amount of guard time required to separate return link transmission from forward link reception by the half-duplex transceiver of a user terminal. The guard time is determined based on a maximum differential round-trip propagation delay and transition times of the half-duplexer transceiver to switch between transmit and receive modes. In a satellite communication system in which a large number of active user terminals are present in a beam coverage, random time offsets are applied to spread approximately equal traffic loads across the time offsets.

An interoferometric fiber optic sensing system uses three optical fibers. A sensing optical fiber is applied to a structure to be monitored to detect displacement or the like by changing its optical path length. A reference optical fiber has a fixed optical path length.

Several sensing optical fibers can be multiplexed; by staggering their optical path lengths, their interference fringes can be separated sufficiently to resolve them.

Methods and apparatus for flexographic color printing, and more particularly for implementing “wet trapping” in flexographic printing using energy curable flexographic liquid inks are presented. Radiation curable inks can be formulated that wet trap over each other without back-trapping onto the plates and anilox units of down-line printing units by controlling the storage modulus of the inklcoating. The storage modulus G′ in the inks can be controlled to ensure that the highest G′ ink is printed ISt down with successive colors being trapped in the order of their (declining) G′ values. An image in wet ink can thus be trapped over a different image in wet ink of a different color without picking the ISt ink back up and redepositing it onto the subsequent plates and rollers in the printing press (back-trapping).

One of the both-end supporting legs (1, 1) is provided with a first motor (M1) to rotate the outside frame (3). The outside frame (3) is provided with a second motor (M2) to rotate the intermediate frame (5). The intermediate frame (5) is provided with a third motor (M3) to rotate the inside frame (7). According to the above-mentioned configuration, the first through third motors (M1 through M3) rotate. The inside frame (7) holding the tested model (J) rotates in the space inside the intermediate frame (5). The intermediate frame (5) rotates in the space inside the outside frame (3). In this manner, rotations are provided around the three rotation axes (2, 4, 6) orthogonal to each other.
