摘要： A permanent magnet dynamoelectric rotating machine comprises a stator provided with windings; and a rotor disposed with an air gap between the stator and the rotor, and provided with a plurality of permanent magnets arranged along the circumference of the rotor and fixed to the rotor. The circumferential length of a surface of each permanent magnet facing the stator is determined so that an induced voltage has a waveform approximate to a sinusoidal waveform to suppress the peak of the induced voltage.

摘要： A motor having a lap winding structure and a manufacturing method therefor, wherein inserts of two different coils are installed side by side in one slot of a stator in a circumferential direction of the stator. All the coils are inserted in slots in succession. Further, a stator having semi-closed type slots formed by protuberances oriented in different directions, is used to control a reduction in the magnetic flux at the inlet of a slot and also to prevent coils from coming off. In a motor having coils of a plurality of phases for generating a rotating magnetic field at a stator, the contact portion of the coil of the desired phase among the coils of the plurality of phases and a portion rising from a slot toward the axis of a core are aligned and disposed to have a shape which prevents them from interferring with end portions of the coils of other phases.

摘要： A tape cassette receiving housing comprises a housing proper portion and a lid portion which is fixed to the housing proper portion through a hinge portion so as to enable to be opened or closed. Shaft portions are formed so as to penetrate into reel driving holes of a supply reel and a take-up reel of a tape cassette received in the housing proper portion. Elastic bodies are attached to outer peripheries of the shaft portions, and the elastic bodies are brought into contact with inner peripheral surfaces of reel driving holes. According to the above construction, a tape cassette is fixed in the tape cassette receiving housing so as not to incline the tape cassette and not to rotate the supply reel and the take-up reel.

摘要： A recording/reproducing apparatus in which recording/reproducing characteristics for the magnetic tape may be stabilized and data errors may be reliably prevented form occurrence. The recording/reproducing apparatus has a magnetic head 81 in which a pair of magnetic core halves 83A, 83B of a magnetic material are abutted to each other via a gap material g to form a magnetic core. Magnetic tape guide units 82A, 82B are provided in the vicinity of the magnetic head 81. The magnetic tape guide units 82A, 82B are formed with magnetic tape suction openings 82b, 82b closed by a magnetic tape 88 adapted for having a sliding contact with the tape slide surface 82a. The magnetic tape suction openings 82b, 82b suck the magnetic tape 88 running on the tape slide surfaces 82a, 82a of the magnetic tape guide units 82A, 82B.

摘要： A tape cartridge for housing magnetic tape includes first and second tape guide portions including upper and lower flanges provided thereon for guiding tape along a predetermined tape path according to rotation of supply and take-up reels of the tape cartridge. The tape is disposed such that an upper edge thereof contacts an inner side of an upper flange of the first tape guide and an inner side of the lower flange of the second tape guide. A width dimension between these two inner sides of the flanges being substantially equal to the width of the tape. This may be effected by mounting the first and second tape guide portions at different heights on a base plate of the cartridge. According to this, it is possible to substantially reduce `offtracking` of tape running in said cartridge.

摘要： A tape cassette comprises a supply and a take-up reel on which tape is wound, a cassette casing for rotatably enclosing the reels therein, a plurality of tape guide pins, each being press-fitted through the inner wall of the casing, for defining a tape path for the tape travelling between the pair of reels. The press-fit section of each guide pin is formed in a predetermined taper in such a manner as to gradually decrease its outer diameter towards its end. The straight press-fit section of the guide pin is formed in such a manner as to include a predetermined geometry of chamfered circumference at its end. In a tape guide pin used in conjunction with a tape guide roller, grease having a predetermined viscosity coefficient is disposed between the associated pin and roller. An electrical insulating cover is provided for surrounding the exposed underside of the electrically conductive lower half of the casing.

摘要： A thermal printer comprises a pair of fixed frames for rotatably supporting a platen which is rotated by a motor and a head unit rotatably supported by the fixed frames through a pair of movable frames and for supporting a thermal head. A pair of pinch rollers are rotatably mounted on the fixed frames, which are selectively brought to a first operating state to feed a paper sheet to the region between the platen and the thermal head, and a second operating state to feed no paper sheet. The thermal head is selectively moved between a first position, in which it is pressed against the platen, and a second position in which it is disengaged from the platen. The thermal head is moved to the first position, at the same time the pinch rollers and moved to the second operating state, while the thermal head is moved to the second position, at the same time the pinch rollers are moved to the first operating state.
