摘要:
This electron microscope (20) comprises: a first imaging device (291); a second imaging device (240) that can be moved away from transmitted light (P); and another detection device (260). The second imaging device is disposed in an observation chamber (230) above the first imaging device, and an attachment portion (231) of the other detection device is disposed at a position rotated 90 degrees from the attachment position of the second imaging device on the same plane on which the second imaging device is disposed. Thus, the second imaging means and the other detector can be attached compactly to the observation chamber disposed on the table surface of a mount housing, whereby an electron microscope can be provided in which workability of the devices and effective use of the table surface are achieved.

In the spectrometer, heavy loads are arranged centrally inside a case having a height smaller than a width, and having a depth smaller than the height. The heavy loads include a vacuum chamber, a vacuum pump which evacuates the vacuum chamber, a sample introduction unit which introduces a sample to be measured and evaporates the sample, an ionization unit which ionizes the evaporated sample and provides it to the vacuum chamber, and an ion detection unit which is connected to the vacuum chamber. Circuit board storage units which store a plurality of circuit boards with a predetermined space therebetween are formed on both sides along a width direction of the case.

A scanning electron microscope includes a main scanning electron microscope unit having an electron optical column and a sample chamber, a controller over the main scanning electron microscope unit, a single housing that houses both the main scanning electron microscope unit and the controller, and a bottom plate disposed under the single housing, the main scanning electron microscope unit and the controller. A first leg member is attached to a bottom face of the bottom plate on a side of the controller with a first opening hole provided through the bottom plate on a side of the main scanning electron microscope unit, and a damper is fixed to a bottom face of the main scanning electron microscope unit and disposed through the first opening hole.
摘要:
A laboratory automation system capable of reducing a wasting time of an operator work by giving a notification that enables a device state and a summary of an operator call to be recognized. The laboratory automation system having notifying means such as a display unit or a speaker which can be recognized by the operator distant from the device, includes a notifying unit for calling the operator, and a notifying unit for notifying a status of the device, in which a state device and a summary of the work conducted by the operator can be easily recognized by the combination of notifications of those notifying units.
摘要:
There is provided a method for handling an aqueous solution containing a water-soluble substance that changes into a water-insoluble substance over time, including a step of bringing the aqueous solution to be treated containing the water-soluble substance that changes into the water-insoluble substance over time into contact with a water-insoluble organic solvent, and extracting the water-soluble substance into the water-insoluble organic solvent. Preferably, the water-soluble substance is alkylbenzene hydroperoxide, and the water-insoluble substance is alkylbenzene hydroperoxide-derived alcohol. Preferably, the aqueous solution to be treated is an alkaline aqueous phase separated in a water-washing step in a process of manufacturing the alkylbenzene hydroperoxide that has an alkali extraction step, the water-washing step, an oxidation step, and a reaction solution separation step.

To provide a method for producing dialkylhydroperoxybenzene by liquid-phase oxidation of dialkylbenzene, wherein the method comprises the following steps, Oxidation step: a step of obtaining a oxidation reaction liquid having pH of 9 to 12, which contains dialkylhydroperoxybenzene, unreacted dialkylbenzene, and by-produced hydroperoxybenzenes by subjecting an oxidation raw material solution containing dialkylbenzene to oxidation reaction, Aqueous solution extracting step: a step of extracting the oxidation reaction liquid with an alkaline aqueous solution to obtain a water layer mainly containing dialkylhydroperoxybenzene and by-produced hydroperoxybenzenes, and an oil layer mainly containing dialkylbenzene, and Recycle step: a step of recycling and feeding at least a part of the oil layer obtained in the aqueous solution extracting step to the oxidation step, wherein the oxidation step comprises two or more reaction sections of a first section and subsequent sections arranged in series, and the temperature of the first reaction section is set to be higher than an average temperature of the whole reaction sections by 2.5° C. or more.
摘要:
A magnetic shielding apparatus having a high shielding effect. With the magnetic shielding apparatus having an opening (for example, a cylindrical magnetic shielding apparatus provided with a door), the door covering the opening is electrically and/or magnetically connected to a main body by means of electrically and/or magnetically connecting members. The magnetic shielding apparatus is higher in magnetic shielding factor than the conventional magnetic shielding apparatus, and a magnetic field measuring apparatus using the magnetic shielding apparatus, capable of measuring biomagnetism generated from an inspection target (a living body), with higher sensibility than before.
