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 invention provides an area grain combine harvester which comprises a walking device, a pneumatic assisting header device, a threshing device, a cleaning device, a pneumatic conveying device, a bagging device, a hydraulic integration device, a driving operation device and an engine device. The walking device is placed at the bottom end of a whole machine. The pneumatic assisting header device is placed at the front end of the whole machine. The threshing device and the cleaning device are arranged behind the pneumatic assisting header device in sequence. The pneumatic conveying device is communicated with an outlet of the cleaning device. The bagging device is placed at the back end of the whole machine and is communicated with the tail end of the pneumatic conveying device. Conveyed seeds are bagged according to area unit quantity. Each time harvesting in one area is over, a corresponding device is operated to carry out seed clearing under a moving-stopping state, and seed mixing between different areas is avoided. Working efficiency is high, the grain breaking rate and the loss rate are low, inner grains can be cleared easily, seed residues are avoided, and the problem that during harvesting, seed mixing is caused by inner residual seeds of machines between different areas is effectively solved.

A magnetic head for use in a perpendicular recording system having a novel shield structure that provides exceptional magnetic shielding from extraneous magnetic fields such as from a write coil, shaping layer or return pole of the write head. The magnetic head includes a write pole, a return pole and a magnetic shield that is magnetically connected with the return pole near the ABS and extends toward the write pole. The shield is formed with a notch at its edge closest to the write pole. The notch assures adequate physical, magnetic, and electrical separation between the write pole and the shield, while allowing un-notched portions of the shield to provide additional magnetic shielding.

A magnetic head having an air bearing surface (ABS) and a first pole tip. A second pole tip is spaced apart from and facing the upper end of the first pole tip across a write gap. A bump extends into a portion of the upper end of the first pole tip and a portion of the bottom end of the second pole tip, the bump being positioned away from the ABS. The bump defines a throat height of the first and second pole tips.

A light receiving device and an image pickup device in which a plurality of light receiving devices are arranged are provided. The light receiving device comprises a single semiconductor substrate and a light receiving device that has a first photoelectric conversion part and a second photoelectric conversion part. The single semiconductor substrate comprises regions of a first conductivity type and regions of a second conductivity type in an alternately multiply stacked manner. Depths of each of the junction surfaces between the regions of first conductivity type and second conductivity type are formed at depths such that light mainly in the blue or red wavelength regions can be photo-electrically converted. The respective detected wavelengths of the first photoelectric conversion part and second photoelectric conversion part are longer than the central wavelength of the blue wavelength region, and shorter than the central wavelength of the red wavelength region.

The present invention aims at providing a three-axis motion table capable of ensuring smooth rotations around three rotation axes orthogonal to each other and decreasing an overall weight. The three-axis motion table according to the present invention has an outside frame (3), an (e.g., approximately square) intermediate frame (5), and an (e.g., approximately square) inside frame (7). The outside frame (3) is rotatably mounted around a first rotation axis (2) by means of a pair of both-end supporting legs (1, 1). The intermediate frame (5) is rotatably mounted around a second rotation axis (4) by means of the outside frame (3). The inside frame (7) is rotatably mounted around a third rotation axis (6) by means of the intermediate frame (5). The inside frame (7) has a holding mechanism for a tested model (J). 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. The pair of both-end supporting legs (1, 1) works as a base for supporting the entire three-axis motion table (A). The pair of both-end supporting legs (1, 1) is more stable than a base (B in FIG. 10) according to the conventional technology using only one vertical rotation axis for supporting one end. The pair of both-end supporting legs (1, 1) is capable of miniaturization and weight saving.
