Abstract: Provided is a reactor exhibiting stable magnetic characteristics. The reactor includes a coil, a magnetic core having an inner core portion and an outer core, and an end surface connecting member disposed between an end surface of the winding portion and the outer core portion. The reactor includes a resin-molded portion integrates integrating the outer core portion and the end surface connecting member, and a plurality of protruding portions provided disposed on an outer surface of the end surface connecting member on which the outer core portion is disposed and that supports the outer core portion at a distance from the outer surface, the resin-molded portion enters a gap formed between the outer surface and the outer core portion by the protruding portions, thereby forming a resin gap between the inner core portion and the outer core portion are being separated from each other by the end surface connecting member.

Abstract: A reactor that includes a coil made of a wound coil wire; a magnetic core on which the coil is arranged, and that forms a closed magnetic path, wherein the magnetic core has an inner core section that is arranged on an inside of the coil; and a heat dissipating sheet that is interposed at least partially between an inner circumferential surface of the coil and an outer circumferential surface of the inner core section that is opposite to the inner circumferential surface of the coil, wherein the heat dissipating sheet is in contact with the coil and the inner core section.

Abstract: Provided is a reactor having a small installation area, low loss, and excellent productivity. The reactor includes a coil having a pair of winding portions and that are arranged side by side, and a magnetic core having a U-shaped core piece that is part of a powder compact. The U-shaped core piece includes a side base that has a portion opposite the ends of the pair of winding portions and uncovered by the winding portions, and disposed across the pair of winding portions, a pair of middle portions that protrude from the side base and respectively disposed inside the pair of winding portions, and an end surface facing a gap, a side extension portion extending from the side base orthogonally from the middle portions, and a central protruding portion protruding from the side base's central region, and are arranged side by side, away from the middle portions.

Abstract: Provided is a reactor having high joining strength between an end surface connecting member and an outer resin-molded portion and excellent reliability. A reactor includes a coil having a winding portion, a magnetic core having an inner core portion disposed inside the winding portion and an outer core portion disposed outside the winding portion, an end surface connecting member that is fixed to an end portion of the inner core portion and disposed between an end surface of the winding portion and the outer core portion, and an outer resin-molded portion that integrates the outer core portion and the end surface connecting member, wherein a detachment preventing portion is formed in the end surface connecting member, the detachment preventing portion being embedded in the outer resin-molded portion and having a detachment preventing shape that suppresses detachment of the outer resin-molded portion.

Abstract: A server is caused to provide to a client computer an annotation function available to other client computers to thereby allow the client computer to communicate with the other client computers using annotations. The server stores on the server viewing information that allows a user of the client computer to view a document with an attached annotation on a screen of the client computer, and the server transmits the viewing information to the client computer. The viewing information includes: document information representing the document in a web-viewable format, such that the document is defined so as to be classified into a plurality of objects which are capable of being designated individually; annotation information representing the annotation in a web-viewable format; and a script to be executed by the client computer for allocating the annotation to the document.

Abstract: A toner developing quantity detection unit operates a plurality of electrostatic recording units to transfer Y, M, C and K color component toner marks onto a belt. A toner developing quantity correction unit detects toner developing quantities per unit area of color toners on the basis of detection signals of the color component toner marks on the belt optically detected by a sensor. The toner developing quantity correction unit corrects the toner developing quantities so as to allow the toner consuming quantities of the plurality of electrostatic recording units to be substantially the same level, on the basis of the thus detected toner developing quantities.

Abstract: High purity crystals of a biphenyltetracarboxylic dianhydride produced by dehydration of a biphenyltetracarboxylic acid, which contain almost no biphenyltricarboxylic acid or its anhydride, or a small amount such as an amount of not more than 0.2 wt. %, are of value to produce an aromatic polyamic acid or polyimide having an increased high molecular weight. The high purity crystals of a biphenyltetracarboxylic dianhydride can be prepared from a biphenyltetracarboxylic acid by a dehydration process wherein the biphenyltetracarboxylic acid is heated under carefully controlled conditions.
