This invention provides a method for producing a glycan with improved yield ratio of streocontrolled glycan. Additionally it provides the building blocks used as the sugar donor and as the sugar acceptor to implement a method for producing the glycan. It also provides a novel compound. It subjects the specific building block A of this invention to electrolytic oxidation in an aprotic organic solvent that contains an electrolyte; and subjects the specific building block B of this invention to glycosylation with the electrolytically oxidized building block A in the method for producing a glycan based on the liquid phase process.

A filter has a port block provided with: an inflow port to which compressed air is supplied, and an outflow port from which purified compressed air flows out. A filter container accommodating an element assembly is attached to the port block. The element assembly has a filter element provided between an upper holder and a lower holder, and a blade cylinder provided inside the filter element. Compressed air supplied from the inflow port and filtered through the filter element is swirled by the blade cylinder.

A tube-fixing tool is improved in assembling property between the tube-fixing tool and the elastic tube, and in production yield of the actuator. A tube-fixing tool is attached to an end of an elastic tube provided with: a soft tube and a cover tube, the soft tube constituting an actuator, the tube-fixing tool comprising: a fixing-tool body having a fitting-cylinder part provided with: a fitting-inner face that is fitted to an outer face of the soft tube; and a fitting-outer face that is fitted to an inner face of the cover tube; and a fixing sleeve having: an inner circumferential face that is opposed to the fitting-cylinder part via the cover tube; and a fastening part that is attached to the fixing-tool body, the cover tube being fixed between the fixing-tool body and the fixing sleeve.

An object of the present invention is to remove foreign matter such as liquid droplets from air with high efficiency using a filter. This filter is used to purify air by removing foreign matter such as liquid droplets and dust from the air. A separation unit is formed with a port block and a separation cylinder, and the port block is formed with a primary port and a secondary port. A collection container is attached to the separation unit, and liquid droplets exhausted from an exhaust port formed at a lower end portion of a separation unit fall down into a collection container. A conical portion of the separation unit is formed with a communication hole through which the separation chamber and the storage chamber communicate with each other, whereby the separation chamber and the storage chamber become equal in pressure to each other.

Filter

This filter is used to purify air by removing foreign matters such as liquid droplets contained in the air. A separation unit () is formed with a port block () and a separation cylinder (), and the port block is formed with a primary port () and a secondary port (). From the secondary port (), the air purified by removing the foreign matters in a separation chamber () of the separation unit () is flowed out. A discharge pipe () for guiding the purified air to the secondary port () is disposed in a center portion of a swirl flow generating chamber (). The foreign matters discharged from the discharging port () are collected in a collection container (). In the collection container (), a baffle platehaving a liquid guiding surface () is provided. A fin () is provided in an outer peripheral portion of the baffle plate (), and the liquid guiding surface () positioned at a center portion of the baffle plate () is flat.

The attaching/removing workability of the collecting vessel of a conditioning apparatus with respect to a port block is increased. A primary-side port and a secondary-side port are formed in a port block, and a female screw partthat is screwed to a male screw partis provided to the collecting vesselthat is mounted to the port block. An annular lock memberis mounted to the opening end of the collecting vesselso as to be movable in the axial direction. A tongue piecethat presses the annular lock membertowards the outside in the axial direction of the collecting vesselis provided to the inside of the annular lock member. A movable-side engagement partthat engages a fixed-side engagement partof the port blockwhen the collecting vesselis rotated to a position of fastening completion is provided to the annular lock member

Vessel attaching/removing device for conditioning apparatus

This swirl flow generator is used to purify air by removing foreign matters such as liquid droplets and dusts contained in the air. A cylindrical blade portion () is arranged in a swirl flow generating chamber () through which the air flows in the axial direction, and the air flowed in the axial direction along the blades () is radially jetted toward inside of the cylindrical blade portion () to form swirl flow. The air supplied into the swirl flow generating chamber () in the axial direction is guided by the closing lid portion () toward the inflow-side end surface of the cylindrical blade portion (). The air flow downward from the outside of the cylindrical blade portion () is prevented by the annular base portion ().

Swirl flow generator

This filter is used for purifying air by removing foreign matters such as liquid droplets contained in the air. A separation unit is formed by a primary port, a port block to which a secondary port is formed, and a separation cylinder attached to the port block. Inside a swirl flow generating chamber of the separation unit, a cylinder blade portion formed by arranging a plurality of blades, which are extended in an axial direction along an inner peripheral surface and also inclined in a circumferential direction, in a cylindrical form is provided. The air flowed into the swirl flow generating chamber is caused to be a swirl flow by the cylindrical blade portion and foreign matters such as liquid droplets are discharged toward a collection container in a separation chamber. The purified air is guided from a discharge pipe to the secondary port.
