A method of producing a chemical includes a fermentation step that converts a fermentation feedstock, through fermentation by culturing a microorganism or culture cells, into a fermented liquid containing the chemical, and a membrane separation step that collects the chemical, as a filtrate, from the fermented liquid with the use of two or more separation membrane modules, and returning the non-filtered liquid to the fermented liquid, wherein in the membrane separation step, timing of the filtration-stop treatment for each separation membrane module is controlled when an intermittent filtration operation including alternately repeating a filtration treatment and a filtration-stop treatment is performed with plural separation membrane modules.

An ink jet recording apparatus includes a slide member slidably supported at a cartridge holder and a lock claw member rotatably supported at the cartridge holder. The slide member slides along an insertion direction of an ink cartridge with respect to the cartridge holder between a first slide position and a second slide position. When the slide member is located at the second slide position, the lock claw member is located at a first rotation position. At this time, the ink cartridge is incapable of being removed from the cartridge holder. When the slide member moves to the first slide position from the second slide position, the lock claw member is located at the second rotation position. At this time, the ink cartridge is removable from the cartridge holder.

The present invention provides an imaging unit, a portable terminal device, and a portable terminal system capable of performing a satisfactory key synthesizing process. An imaging unit mainly includes an imaging section, a conversion section, and a key signal generating section. The conversion section converts the format of the imaged image data output from the imaging section from YUV format to RGB format. The key signal generating section generates a key signal based on each pixel data configuring the imaged image data and the reference data for the imaged image data input from the imaging section. The key signal generating section also outputs foreground image data having the generated key signal and the corresponding pixel data of RGB format as minimum configuring unit. An image synthesizing section of a main unit generates synthesized image data by overlapping the foreground image data from the imaging unit and the background image data stored in a RAM based on the key signal contained in the foreground image data.

An engine control apparatus is provided with an engine, an ignition device, a valve timing changing mechanism, an intake valve close timing detecting device, a supercharger and a controller. The engine achieves a Miller cycle by the valve timing changing mechanism setting an intake valve close timing to occur after a bottom dead center timing. The controller controls an ignition timing of the ignition device, the open timing of the intake valve and the close timing of the intake valve. The controller retards the ignition timing during supercharging and when a detected value of the intake valve close timing is earlier than a target value of the intake valve close timing by at least a prescribed value in comparison with a situation in which the detected value matches the target value of the intake valve close timing.

An ink supplying and collecting apparatus includes a case, ink cartridges detachably attached to the case, and a collecting container detachably attached to the case. The ink cartridges supply ink to a recording head of a printer via ink supply tubes. The collecting container collects ink drained from the recording head via an ink drain tube. The case is located outside of and is separate from the printer. Thus, the sizes and shapes of the ink cartridges and the collecting container can be freely designed.

Disclosed is a process for producing an oxazoline derivative from a non-protected sugar in a simple manner. Also disclosed is a process for producing a glycoside by utilizing the product of the aforementioned process. A sugar oxazoline derivative is synthesized in one step in an aqueous solution from a sugar having a free hemiacetalic hydroxy group and an amido group by using a haloformamidinium derivative as a dehydrating agent. A glycoside compound is produced by using the oxazoline derivative as a sugar donor and also using a sugar dehydrogenase. The method can be applied to the production of a compound having a long sugar chain, and is therefore useful for the production of a physiologically active oligosaccharide, a carrier for a drug delivery system, a surfactant, a carbohydrate-based drug, a glycopeptide, a glycoprotein, a carbohydrate polymer or the like.

A guiding device guides, in a main body of a liquid ejection apparatus, a flexible passage forming member having a passage therein in a predetermined routing direction while curving the passage forming member. The guiding device includes a holding member. The holding member is engaged with a curved section of the passage forming member, and holds the curved section in an undeformable manner in the apparatus main body. The holding member guides the passage forming member in the routing direction. Thus, the guiding device is capable of efficiently routing passage forming members while bending the members in a body of a liquid ejection apparatus.
