An air compressor includes: a motor; a compression mechanism that is driven by the motor and that is configured to generate compressed air; a tank that is configured to store the generated compressed air; a load acquisition part that is configured to acquire a load applied to the compression mechanism; and a control part that is configured to control a rotation of the motor. The control part is configured to perform control for changing a TN characteristic of the motor in response to the load of the compression mechanism acquired by the load acquisition part.

Air compressor

An air compressor includes a tank unit that stores compressed air, a motor unit that generates compressed air to be stored in the tank unit, a pressure detection unit that detects a pressure value in the tank unit, and a control unit that drives the motor unit when a pressure value in the tank unit detected by the pressure detection unit is equal to or less than a motor start pressure value, and stops the motor unit when the pressure value in the tank unit detected by the pressure detection unit is equal to or greater than a motor stop pressure value. The control unit changes at least either of the motor start pressure value or the motor stop pressure value every time when a predetermined time passed.

A gate valve is provided with a main body, and a sealing member which comes into contact with the peripheral edge of a gate when the gate valve is closed. The sealing member includes a protruding first section and a protruding second section which are disposed to extend along the peripheral edge of the main body and protrude from the primary surface when the gate valve is open. A protrusion amount of the first section from the primary surface is greater than a protrusion amount of the second section from the primary surface. The first section is disposed inner to the inner periphery of the primary surface than the second section.

The case is provided between a pair of air tanks which are disposed parallel to each other at an interval and on a lower side of at least either of an electric motor and compressors in such a manner as to be oriented downwards so that the base is located at an upper position. An air flow generated by cooling fans which are driven by the electric motor is introduced to flow along the base of the case to thereby cool the heat generating components via the case.

A stable Ca preparation in solution form even at high concentration is provided. The aqueous preparation of Ca includes water, Ca, compounds of Formula I and Formula II.

At least partially, the complex forms colloidal particles. The aqueous preparation is transparent. pH is equal to or higher than that of slightly acid; [A, A, A, A, Aand Aare independently Oor OX. X represents a monovalent or polyvalent cation].

In a vacuum gate valve, a seal member for sealing a gate opening part is bonded to an outer edge part of a planar seal plate that is disposed in such a manner that the planar seal plate is opposed to a valve seat surface of the gate opening part and comes into contact with the valve seat surface. The seal member includes a vacuum seal part that is located on a side farther from the gate opening part and maintains the sealability of the gate opening part when the gate opening part is closed, and also includes a radical seal part that is located on a side closer to the gate opening part and that prevents the seal member from being affected by a treatment gas in the gate opening part when the gate opening part is closed. The vacuum seal part is made of a rubber elastic body, and the radical seal part is configured by providing a radical resistant body that is provided with an excellent radical resistance on the rubber elastic body.

Method for producing at low cost bellows which show high durability even when used in a quite reactive atmosphere. The method for manufacturing bellows includes the steps of: I: forming an untreated bellows from a flat base plate, the base plate including 15 to 30 wt % of Cr, 5 to 40 wt % of Ni, 0.9 to 6 wt % of Al, less than 1 wt % of Mo, less than 0.1 wt % of Mn, less than 0.1 wt % of C, less than 0.1 wt % of S, less than 0.1 wt % of P and a balance of Fe and an unavoidable impurity (relative to 100 wt % of the base plate); and II: heating the untreated bellows at a temperature of 750 to 895&#xb0; C. in an atmosphere which contains water and hydrogen and in which the volume ratio of hydrogen to water (H/HO) is in the range of 2&#xd7;10to 1&#xd7;10, thereby forming an AlOpassivation film on a surface of the untreated bellows.
