A synthesis experiment automation system is provided with a robot, which transports synthesis reaction containers from a reaction container rack to a dispensing/separation position of a dispensing and separation device, and transports the synthesis reaction containers to a predetermined position in a temperature regulator unit of a reaction device, where a reaction is carried out under previously set experiment conditions; and with a computer, which controls the actions of the robot and the operations of the dispensing and separation device and the reaction device in accordance with a plurality of previously set experiment conditions. Accordingly, the synthesis experiment automation system is capable of simultaneously performing a plurality of different experiments as complex as those usually performed by researchers, and, moreover, has a large number of possible experiment operations, and can easily be improved and/or extended.

A method of detecting a defect on the surface of a structure using an infrared radiometric thermometer. It is determined that there is a lifting defect at a region of the surface if the region has a temperature difference of 0.3.degree. C. or more in comparison with a surrounding region and has an area of 200 cm.sup.2 or more. The temperature of the surface of the structure is obtained using the infrared radiometric thermometer in a period of time from 19:00 p.m. on a day when it is clear at least in the daytime to 4:30 a.m. on the next day.

When conducting preprocessing to extract targeted components sample solution, the purpose is to be able to conduct the processing in a shortened length of time by greatly shortening the entire processing time, even if the number being processed is increased. A single needle holder, to which a single needle nozzle is attached to take sample solution into test tubes arranged in a sample rack and inject the sample solution into solid phase extraction tubes, and a multiple linked needle holder for injecting solvent, to which multiple needle nozzles are attached to simultaneously supply multiple solid phase extraction tubes with solvent, are mounted interchangeable on a head, the movement of which can be controlled in the directions of three orthogonal axes; and when aforementioned needle holders are mounted on said head, flow rate control pumps, which are switchable between the intake and discharge directions, are mounted through the piping which connects those needle nozzles with the solvent supply sources.

A development device includes a development casing for containing two-component developer, a developer bearer, a developer regulator to adjust an amount of developer carried on the developer bearer, a first developer conveyance member to supply developer to the developer bearer, a second developer conveyance member to transport axially developer separated from the developer bearer, first and second conveyance channels divided by a partition, in which the first and second developer conveyance members are respectively provided, and a removable sheet member to cover the developer bearer in an area facing the developer regulator, the first and second conveyance channels, and the partition. A first end portion of the sheet member extends from the second conveyance channel outside the development casing through a through hole formed in the development casing, and a second end portion thereof is retained by a retainer at a position outside the developer regulator.
摘要:
A waste toner storage unit detachably mountable to an image forming apparatus includes a waste toner container and an inner cover integrally attached to the waste toner container. The waste toner container stores waste toner recovered after an image forming process. The inner cover is located at a region of the waste toner storage unit that does not store waste toner.

Developing devices, process cartridges and image-forming apparatuses, having a chamber for conveying recovered developer on the top of another chamber for conveying supplying developer, where the developer is conveyed by screws inside the chambers respectively, when mixing and conveying the developing agent, a shielding member which separates the chambers, a guide section is provided in the shielding member to guide a developing agent which has left a developing roller toward the screw in the upper chamber, and a third communication section is provided next to the guide section, at the back of where the guided developer contacts the screw wings in the upper chamber, and the third communication section communicates the chambers with each other, and the third communication section is provided from center to downstream in the conveyance direction of the developer by the screw upper.
摘要:
A lubricant applicator includes a solid lubricant, a lubricant applying member to apply the solid lubricant to a target object, a biasing member to bias the solid lubricant toward the lubricant applying member, and a regulating member to regulate the solid lubricant, which is biased toward the lubricant applying member by the biasing member, to prevent the lubricant from separating from the lubricant applying member by more than a predetermined distance. The regulating member is switchable between a regulating state for regulating the solid lubricant not to separate from the lubricant applying member by more than the predetermined distance and a non-regulating state.
