A drug discovery screening apparatus improves a testing operation efficiency. The drug discovery screening apparatus comprises an image measurement unit, an incubator unit integrally connected to the image measurement unit, a fixed stage disposed at the incubator unit, first conveyance for taking out one of plates stored in a carousel of the incubator unit and conveying the plate onto the fixed stage, second conveyance for taking out the plate conveyed onto the fixed stage and conveying the plate onto an XY stage disposed at the image measurement unit, and a control unit. The second conveyance comprises first and second conveyance arms, respectively supported horizontally by a conveyance unit support section, which convey the plates onto the fixed stage and XY stage so as to allow the respective plates to cross each other.
摘要:
A method for manufacturing a substrate chip including the steps of: setting the thickness of at least a part of a metal wiring pattern unit provided on the raw substrate to be 0.1 μm to 5 μm; forming a groove for creating at least a crack in the surface of the ceramic substrate along a planned cutting line which passes through the part of the metal wiring pattern unit by using a cutting wheel having a cutter blade being formed into substantially V shape in cross section along the circumferential portion of the disk rotating wheel; and cutting the raw substrate by giving load from just behind of the groove. When manufacturing metallized ceramic substrate chips by cutting (dividing) the ceramic substrate on the surface of which wiring patterns made of a metal film is formed, the method is capable of effectively using the base material, inhibiting defects in the metallized portion, and efficiently manufacturing the substrate chips in high yield.

It is an object to provide an individual voltmeter apparatus utilizing a switching circuit which suppresses the variation of the consumption power of the unit cell of a set of batteries. The power supply of a first current path 2m1 and a second current path 2m2 of a level shift circuit 2m is between the unit cell Vm+1 and V1, and between the unit cell Vm+1 and one lower rank cell Vm, respectively. The same current, which responds to all semiconductor switches, flows in the first current path 2m1. In the second current path 2m2, a larger current is provided to the second current path in which the semiconductor switch is connected to the higher rank unit cell.

摘要:
An apparatus for optical measurement is formed as a one-piece molding. The apparatus has a reaction vessel and pre-treatment vessels, at least part of the partitioning wall between the both serves as an optical waveguide body, and a light absorber vessel is formed adjacent the reaction vessel (24). Simplification of the process of manufacture thus is attained. With a light absorber accommodated in the light absorber vessel, (25), reaction components of excitation light and other noise light components that are propagated through the optical waveguide body can be sufficiently attenuated to improve the S/N ratio of the optical measurement.
