An object is to provide an adsorbent using activated carbon fiber, the adsorbent being suitable for motor vehicle canisters and enabling reduction in pressure loss. An activated carbon fiber sheet for a motor vehicle canister fulfils the following conditions (1) to (4). (1) The sheet has a specific surface area ranging from 1100 to 2300 m/g. (2) The sheet has a density ranging from 0.010 to 0.200 g/cmor less. (3) The sheet has a thickness ranging from 0.1 to 100.00 mm. (4) The sheet has a fiber size of 13.0 μm or larger.

Activated carbon fiber sheet for motor vehicle canister

A problem to be solved by the present invention is to provide a new form of adsorbent suitable for a motor vehicle canister. An activated carbon fiber sheet satisfies one or two or more of conditions for indices, such as a specific surface area, a pore volume of pores having a given pore diameter, and a sheet density. An embodiment, for example, may have: a specific surface area ranging from 1400 to 2300 m/g; a pore volume ranging from 0.20 to 0.70 cm/g for pores having pore diameters of more than 0.7 nm and 2.0 nm or less; an abundance ratio R, which is a ratio of a pore volume of micropores having pore diameters of 0.7 nm or less occupied in a pore volume of micropores having pore diameters of 2.0 nm or less, ranging from 5% to less than 25%, and a sheet density ranging from 0.030 to 0.200 g/cm.

An object is to provide a new form of adsorbent suitable for a high performance canister. An adsorbent including activated carbon is used as the adsorbent for the canister and satisfies the following conditions. Pexpressed by Equation 1:×100  (Equation 1)is 18% or more, in Equation 1, X represents an amount of adsorbed n-butane gas per 100 parts by weight of the adsorbent at 25° C. under an atmosphere where a gas pressure of n-butane gas is 0.2 kPa, and Y represents an amount of adsorbed n-butane gas per 100 parts by weight of the adsorbent at 25° C. under an atmosphere where a gas pressure of n-butane gas is 100 kPa.

An object of the present invention is to provide a new form of adsorbent suitable for a motor vehicle canister. An activated carbon fiber sheet satisfies one or two or more of conditions for indices, such as a specific surface area, a pore volume of pores having a given pore diameter, and a sheet density. An embodiment, for example, may have: a specific surface area ranging from 1400 to 2200 m/g; a pore volume ranging from 0.20 to 1.20 cm/g for pores having pore diameters of more than 0.7 nm and 2.0 nm or less; and a sheet density ranging from 0.030 to 0.200 g/cm.

Stator terminals are fastened between head portions and coupling seats in a state of surface contact by screwing relay members onto external screw thread portions of output terminal bolts. Three-phase wire terminals are fastened in a state of surface contact to end surfaces of the relay members at opposite ends from the coupling seats by screwing nuts onto the external screw thread portions of the output terminal bolts. In addition, insulating tubes are interposed between the relay members and extraction apertures so as to cover outer sides of the relay members.

Claw-shaped magnetic poles are alternately disposed along the rotation plane of a rotor of an electric rotating machine, and a permanent magnet is disposed between the claw-shaped magnetic poles. Surface of the permanent magnet is coated with a coating layer. The coating layer is composed of a anticorrosive material performing sacrificial anticorrosion (metal flake in a coating film rusts prior to a matrix resulting in protection of the matrix) such as inorganic material containing zinc and a film of the anticorrosive material is formed by spraying. Ionization tendency of zinc is larger than that of iron composing the permanent magnet, and the permanent magnet is difficult to be rusted owing to the sacrificial anticorrosion. Consequently, anticorrosion of the permanent magnet disposed between the claw-shaped magnetic poles is improved.
