摘要:
An X stage (21) arranged on the front edge of a table (11) is movable in the X-axis direction along a rail (23). The X stage (21) supports a light projecting device (70) for illuminating a printed circuit board (PCB) and an imaging device (80) for imaging an inspection area illuminated by the light projecting device (70). An image obtained by the imaging device (80) is displayed on a display device (13). A Y stage (41) is movably provided along a rail (33) on a base (10). A board supporting member (50) for supporting the board (PCB) is pivotably attached to the Y stage (41) at front portion thereof. An inspector judges whether or not soldering is acceptable while seeing the image displayed on the display device (13). When it is judged that soldering is unacceptable, the inspector can correct an unacceptable soldered portion by drawing out the Y stage (41) forward and obliquely raising the board supporting member (50).

An operator actuates keyboard (22) to register board name of a board for teaching (ST11), sets a reference board (1S) on a Y-axis table unit (4) to actuate a start key (ST12), inputs reference points of the reference board (1S) to be set to an original position (ST13), takes a picture of a predetermined area on the reference board to teach a mounting position (ST14), and reads data about component image and its decision criteria of the corresponding component from a component kind table (19) to be stored as teaching data (ST15). This operation is repeatedly executed until all components are taught to a mounted component inspection device which inspects mounting qualities of a plurality of components mounted on an inspected board.

Soldering condition information such as the position and angle of a soldering iron, amount of solder supplied and heating time is stored beforehand, for each grouping of parts, in a part classification table (26) for soldering purposes. Parts to be mounted on a board are stored, in correspondence with the board ID, on a floppy disk of a floppy disk device (24). When the board ID is entered, the parts to be mounted on the board are displayed on a display unit (23). The operator reads out the part classification table (26) for soldering purposes and designates soldering correction information that corresponds to the part groups to which the parts belong. As a result, a teach-data table (27) in which soldering condition information has been stored in correspondence with the parts is created. Soldering is executed automatically in accordance with the teach-data table (27).

The present invention provides a system in which a recombinant plant expressing a target peptide is orally administered to thereby achieve exertion of the function of the peptide, along with the genetically recombinant plant, and the present invention relates to a carrier system for oral administration of a target peptide by oral administration of a plant (potato) that expresses a target peptide by expressing for example a fused gene obtained by fusing the LRE1 gene coding for the immunogenic peptide LRE1 derived from the Leucocytozoon caulleryi 2nd-generation schizont with a Norwalk virus coat protein gene, along with the relevant genetically recombinant plant, and thus, in the present invention the orally administered target peptide can reach an intended destination (such as the intestinal mucosa) without being decomposed in the digestive tract, so that the function of the target peptide can be induced.
摘要:
A pneumatic rotary tool comprises a housing, a square drive output member supported by the housing for rotational movement, and a pneumatic motor disposed in the housing for driving rotation of the square drive. A valve is disposed in the housing for rotary movement between a first position in which pressurized air powers the motor in a forward direction and a second position in which pressurized air powers the motor in a reverse direction. An actuator supported on the housing for translational movement is connected to the valve by a lost motion connection system. The lost motion connection system comprises first and second connector elements that are engaged for generally conjoint movement in a first direction and for relative sliding movement in a second direction generally perpendicular to the first direction.

The method and apparatus are provided for preparing a slurry for a CMP apparatus with which mixing accuracy for a slurry is improved and accurate measurement is automatically accomplished for H2O2 as a small amount of additive. A slurry preparation apparatus for a CMP apparatus comprises a tank for preparing the slurry, a stock solution feeder for the slurry which feeds a stock solution for the slurry into the tank, and a concentration measurement instrument located outside the tank, which is capable of measuring an additive concentration in the slurry in the tank. The concentration measurement instrument measures the additive concentration in the slurry in the tank, and the amount of the stock solution for the slurry to be supplied is controlled according to the measurements.

摘要:
To make it difficult to view streak unevenness in alignment generated at the boundary of alignment layers even when an alignment-layer material is applied onto a color-filter substrate several times to form an alignment layer. When an alignment-layer material is applied onto a color-filter substrate 1 having color filters (R, G, and B) on the surface with a droplet discharge head 3 to form an alignment-layer train 4a, the lateral front end L1 of the train 4a is formed on the color filter (B) displaying blue. When the alignment-layer material is then applied to the following alignment-layer application train to form an alignment-layer train 4b, the lateral rear end L2 of the train 4b is overlapped with the lateral front end L1 of the preceding alignment-layer train 4a to form an overlapped portion 4c. Since the overlapped portion 4c is formed on the color filter (B) displaying blue which has the lowest visibility of the three primary colors of light, streak unevenness in alignment generated at the boundary is difficult to view from the exterior.

Aqueous dispersion polymerization of tetrafluoroethylene (hereinafter referred to as TFE) is conducted in the presence of a paraffin wax, a polymerization initiator and an emulsifier at least once and then the paraffin wax is recovered. The recovered paraffin wax is used for aqueous dispersion polymerization of TFE in the presence of a polymerization initiator and an emulsifier.
