This document creation device () divides common sections of documents of a plurality of diverse specifications into unit documents (), manages and shares the unit documents, groups similar unit documents () and manages and stores the similar unit documents, couples unit documents to a set serving as one edited document on the basis of an edited document configuration (), which is a list of unit documents coupling to the edited document, or couples the unit documents to an electronic file of one edited document, wherein, during said coupling, rewriting is performed such that, when referring to a group in which the content embedded in the unit documents is a set of unit documents, a document which belongs to the referenced group and which is included in the edited document configuration is referred to.

Document creation device

A stator includes a stator core having a plurality of slots in a circumferential direction about an axis and having an end surface in a direction of the axis, and a first coil and a second coil of different phases which are wound on the stator core in distributed winding. A winding factor is 1. Each of the first coil and the second coil has winding portions, the number of which corresponds to the number of poles. The winding portions include first and second winding portions adjacent to each other in the circumferential direction. The first and second winding portions are inserted into one slot of the plurality of slots and extend from the one slot to both sides in the circumferential direction on the end surface. The first and second coils are annularly disposed in different positions in a radial direction about the axis on the end surface.

Stator, motor, compressor, air conditioner, and manufacturing method of stator

Included are a pair of insulators arranged on axial end surfaces of a split core, and an insulating film attached to lateral side surfaces of the tooth part, for insulating the split core from a coil wound around the tooth part. Each insulator includes projections projecting further than a tooth front end part in the circumferential direction, slits which are formed in the respective projections to a corresponding axial end surface side of the tooth front end part and into which the insulating film is inserted, and ribs formed, on an end surface side in the circumferential direction, in the respective projections. The insulating film inserted into the slits is folded back to a back yoke part side with the ribs interposed therein, and fixed by being interposed between the ribs at tip portions of projections of adjacent insulators. Accordingly, the insulating film can be assuredly fixed and prevented from escaping from a slot.

Stator for electrical rotating machine

To provide a spool for a coil winding device capable of preventing poor insulation caused by a leakage of coil wires without initially inserted coil wires staying at the vicinity of slot openings. A spool for a coil winding device of this invention includes a plurality of coil winding surfaces increased stepwise in diameter from the bottom upward in a state where the spool is disposed on the coil winding device. The spool includes a front spool part and a rear spool part, which are placed at a distance from each other so that each turn of coil has a length corresponding to arbitrary lamination thickness of the stator core. The plurality of coil winding surfaces includes a coil winding surface corresponding to the outermost coil that is formed so that a portion in a radial pattern from the vicinity of a portion corresponding to a central axis of the stator core towards an opening of the slot in which each coil is loaded is extended at least to a position corresponding to a core back where the roots of the teeth outside the slot of the stator core are connected.

Spool for a coil winding device and method of loading coils

An object of the invention is to provide an armature of an electric motor that provides a maximum of space for winding without causing an increase of the magnetic resistance and reduction of the coil space factor. The armature of the electric motor includes a stator yokeof a stator corewherein a plurality of the stator coresforms a substantially annular shape; and a film insulatorformed corresponding to a toothand a stator yokeof the tooth, shoesandbeing provided at locations corresponding to both side ends of a front portion of a protrusionof the tooth, the film insulatorbeing fittingly fixed to groovesandby its being sandwiched between a connection-side insulatorand an opposite-side-of-connection insulator, the insulatorsandhaving groovesandat roots of the shoesand, respectively, along both side endsof the front portion of the tooth

Armature of electric motor

A stator iron core of an electric motor including plural magnetic pole segments. Each of the pole segments include a back yoke portion, a teeth portion projected from the back yoke portion, a connection portion provided to the back yoke portion for connecting adjacent magnetic pole segments, and a stepped-shaped notch on an outer circumference of the back yoke portion. Further, the stator iron core is circularly formed by bending the connection portions of the plural magnetic pole segments.

Stator iron core of electric motor, manufacturing method thereof, electric motor, and compressor

A stator iron core of an electric motor including plural magnetic pole segments connected and confronted by plural confronting surfaces. Further, two of the confronting surfaces respectively include a V-shaped projection and a V-shaped recess.

A recording and/or reproducing apparatus for a recording medium, such as a magnetic tape, includes a recording and/or reproducing unit, a main body portion, a signal line and a take-up mechanism. The main body portion houses the recording and/or reproducing unit. The external equipment includes an input unit for entering a signal for setting the operating mode of the recording and/or reproducing unit and an electro-acoustic transducer for converting signals from the recording and/or reproducing unit into audible sound. The external equipment may be attached to and detached from the main body portion and exchanges signals with the recording and/or reproducing unit. The signal line interconnects the external equipment and the recording and/or reproducing unit. The signal line has its one end connected to the external equipment and its other end connected to a circuit board housed within the main body portion for exchanging information signals with the recording and/or reproducing unit. The take-up mechanism takes up the signal line and houses it within the main body portion. The take-up mechanism is arranged on the circuit board within the main body portion.

Recording and/or reproducing apparatus with external controller and

A recording and/or reproducing apparatus, such as a tape recorder, includes a recording and/or reproducing unit housed within a main body portion, an electro-acoustic transducing section, an actuating input unit, first and second connection cord assemblies and first and second cord take-up units. The recording and/or reproducing unit records and/or reproduces the information on or from a recording medium, such as a magnetic tape. An electro-magnetic transducer is fed with information signals reproduced by the recording and/or reproducing unit. An actuating input unit, removably mounted on the main body portion, sets or switches the recording or reproducing state of the recording and/or reproducing unit. The first connection cord assembly interconnects the actuating input unit and the recording and/or reproducing unit for exchanging information signals, and the second connection cord assembly interconnects the electro-acoustic transducing unit and the actuating input unit. The first take-up unit is provided in the main body portion for taking up the first connection cord assembly and the second take-up unit is provided in the actuating input unit for taking up the second connection cord assembly.
