Abstract: A bipolar transistor includes a collector layer, a base layer, and an emitter layer that are formed in this order on a compound semiconductor substrate. The emitter layer is disposed inside an edge of the base layer in plan view. A base electrode is disposed on partial regions of the emitter layer and the base layer so as to extend from an inside of the emitter layer to an outside of the base layer in plan view. An insulating film is disposed between the base electrode and a portion of the base layer, with the portion not overlapping the emitter layer. An alloy layer extends from the base electrode through the emitter layer in a thickness direction and reaches the base layer. The alloy layer contains at least one element constituting the base electrode and elements constituting the emitter layer and the base layer.

The connection portion has, at an edge portion thereof, a cut in a direction crossing the longitudinal direction so as to correspond to a predetermined folding position of the sheet bundle for the purpose of facilitating the folding of the connection portion, and the cut is formed inward from the edge portion so as to have a substantially triangular shape and is provided on both edge portions of the connection portion of the paper-made staple.

Abstract: A sheet processing device that bonds sheets to one another and then folds a resultant sheet bundle. The sheet processing device includes a stacker section that sequentially stores sheets moved thereto, an adhesive-binding unit that applies an adhesive onto sheets sequentially stored in the stacker section one by one in a sheet moving direction to bond the sheets to one another, a moving member that moves the sheets to an application position of the adhesive-binding unit, and a folding processing section that folds a sheet bundle formed by the bonded sheets at a predetermined folding position. When the number of sheets to be bonded by the adhesive-binding unit applying the adhesive onto the sheets exceeds a predetermined number, the adhesive is applied at two positions separated from each other across the folding position.

Abstract: The present invention is to provide a sheet bundle binding device capable of easily removing some sheets from a sheet bundle that has been subjected to staple-free binding. A corner Sc of a first sheet bundle which is accumulated on a processing tray is subjected to proper binding using a staple needle by a staple binding unit. Then, a corner of a second sheet bundle obtained by accumulating additional sheets on the first sheet bundle is pressed and deformed between crimping toothed parts of a staple-free binding unit to temporarily bind the second sheet bundle. Thus, the additional sheets can easily be removed from the second sheet bundle.

Abstract: A sheet post-processing device includes a conveying section that conveys a paper sheet; a punch section that punches punch holes in the paper sheet conveyed by the conveying section; a stacker section that stores the paper sheet in which the punch holes are punched by the punch section; a binding section that binds a paper sheet bundle stored in the stacker section with a binding member; and a controller that controls the above sections. The controller selectively performs a ring binding mode and a direct binding mode. The ring binding mode is a mode in which punch holes are punched in the paper sheet by the punch section and then the binding member is made to penetrate the punch holes for binding. The direct binding mode is a mode in which the binding member is directly driven into the paper sheet bundle without punching the punch holes in the sheet.

With this configuration, the fore edge side of the folded and saddle-stitched sheet bundle can be bound by temporary binding. Thus, a sheet processing device capable of ensuring the security of a saddle-stitched sheet bundle can be provided.
