An antenna which can be used in different communication standards with a simple structure is disclosed. The antenna includes an antenna section which receives/transmits radio waves, input/output ports to which a signal to be input to the antenna section is input and from which a signal output from the antenna section is output, and transmission lines each of which connects the antenna section to a corresponding input/output port.

There are provided bookbinding apparatuses that wrap a bundle of sheets with a cover and form back corners, and have a detecting unit for detecting a wave amount of a bundle of sheets. A type of such an apparatus includes a controller to control a time period to form back corners, based on a result of detection by the detecting unit. Another type of such an apparatus includes a controller to control a pressure applied to form back corners based on a result of detection by the detecting unit. Still another type of such an apparatus includes a controller to control a time period and pressure applied to form back corners, based on a result of detection by the detecting unit.

Replacement time for the cutting board used in the sheet cutting apparatus is detected. A sheet cutting apparatus has a cutting blade to cut a set of sheets by moving in an oblique direction which includes first component of a perpendicular direction to a face of the set of sheets and as second component of a parallel direction to the face, a cutting board to receive the cutting blade, a movable unit to move the cutting board to a face of the cutting blade, and an end detector to detect a moveble end of the cutting board.

A paper post-processing apparatus for folding a paper ejected from an image forming apparatus at a paper folding process section, having a pair of folding rollers; a pair of fold/transporting rollers each of which contacts with each of the pair of folding rollers; a driving unit; a folding roller moving unit; and a drive direction switching unit. When transporting a paper without folding the paper, the holding roller moving unit moves the folding rollers to a releasing position, and the drive switching unit switches the folding rollers to the same rotation direction with each other; and when folding the paper, the holding roller moving unit moves the folding rollers to the pressure contact position, and the drive switching unit switches the folding rollers to the reverse rotation direction with each other.

A nitrile resin composition having excellent transparency, antistatic properties and practical physical properties. The composition comprises (A) 80 to 97 wt. % of a nitrile resin which is obtained by graft copolymerization, in the presence of 3 to 30 parts by weight of a rubbery polymer containing at least 50 wt. % of a conjugated diene unit, of 100 parts by weight of a monomer mixture containing an unsaturated nitrile and an alkyl methacrylate, and has, as a matrix component, 65 to 80 wt. % of an unsaturated nitrile unit and 20 to 35 wt. % in total of an alkyl (meth)acrylate unit and a unit of a further monomer copolymerizable with the unsaturated nitrile and alkyl (meth)acrylate; and (B) 3 to 20 wt. % of a polyether ester amide, wherein the ratio of the melt viscosity of the component (A) to that of the component (B) at 210.degree. C. is 0.5 to 5 at a shear rate of 10.sup.2 sec.sup.-1 and 0.5 to 3 at a shear rate of 10.sup.3 sec.sup.-1 and the difference of the refractive index between the matrix component (A) to the component (B) is 0.2 or less.
摘要:
In a vibrating motor, an eccentric weight is attached to one end of a rotation shaft that projects linearly from a motor housing. The vibrating motor causes the gravity center of the weight to rotate about the rotation shaft so as to produce a vibration. A disk-shaped anti-bending piece is provided on the rotation shaft coaxial with it. This anti-bending piece faces an anti-bending surface provided on some kind of supporting member when the housing is supported by the member, the piece being situated at a predetermined distance from this surface. If the shaft bends, the piece strikes the surface and the linear shape of the shaft is restored due to its own elasticity. Hence, even if the motor suffers an unexpected load, the rotation shaft does not buckle due to the weight of the eccentric weight.
