Patent number: 6052264Abstract: A method and apparatus is disclosed for predicting capstan slipping in belt-driven tape cartridges. The method predicts the occurrence of capstan slip conditions between the belt capstan of a belt-driven tape cartridge and the rotating elastomeric drive roller of the tape drive. To predict capstan slip conditions, the method determines a critical velocity value corresponding to a critical slip condition based on a relationship between the drive force which rotates the cartridge belt capstan, and on the normal force of the drive roller against the cartridge belt capstan. A threshold velocity value corresponding to the drive and normal forces is selected at a point where the relationship between the drive and normal forces would not yet encounter the critical slip condition. The steady-state tape velocity is monitored during operation of the tape cartridge in the tape drive, and an imminent capstan slip indication is provided when the steady-state tape velocity reaches the threshold velocity value.Type: GrantFiled: December 18, 1997Date of Patent: April 18, 2000Assignee: International Business Machines CorporationInventor: Lance Williamson Curtis

Patent number: 5982577Abstract: A novel system, e.g., an audio cassette player, is provided herein. The system simultaneously provides mechanical motion driven by a rotatable drive shaft which is rotating at a continuous predetermined desired speed, and for generating a voltage output by an electrical generator having a rotor which is rotating at a continuous predetermined desired speed, the rotatable drive shaft being non-concentric with, being laterally-spaced-apart from, and being parallel to the rotor. The system includes a prime mover which comprises a windable driving spring, which, in turn, includes an interconnecting drive train for separately drivably connecting the driving spring both to the rotatable drive shaft and to the rotor of the electrical generator. The interconnecting drive train comprising a gear train, which has a driving section which is connected to the driving spring means and which is common for driving both the rotatable drive shaft and the rotor at the electrical generator.Type: GrantFiled: July 28, 1997Date of Patent: November 9, 1999Inventors: Paul Brown, Anie Galipeau

Patent number: 5969900Abstract: The tape drive unit of the present invention is constructed such that the reverse rotation of a motor (16) causes a mode cam (32) to drive for setting any mode of normal play, reverse play, fast forward and rewinding. Thereafter the forward rotation of the motor (16) causes a reel shaft (3) or a reel shaft (4) to rotationally drive according to the mode and a head base (51) is slid in normal play or reverse play modes, to set up a magnetic head and pinch rollers. With such construction, each operation of normal play, reverse play, fast forward and rewinding can be performed without using a plunger or microcomputer, thereby eliminating the fear of troubles due to the plunger malfunction or a microcomputer bug.Type: GrantFiled: August 7, 1997Date of Patent: October 19, 1999Assignee: Sony CorporationInventor: Kunio Shimizu

Patent number: 5969918Abstract: A cassette adaptor is disclosed, in which a head cover for accommodating the magnetic head is elastically supported on the head spring in such a manner that the height of the recording head and the head gap on the signal transmission side can be automatically adjusted in accordance with the tape running position of the reproduction head of a cassette tape reproduction apparatus and in such a manner that the reels can be positively prevented from being driven under no load. The head cover includes a head guide in contact with a reproduction head and at least a dummy tape member in mesh with the tape guide of the cassette tape reproduction apparatus with the cassette adaptor mounted thereon. The head cover thus guides the magnetic head to a position opposed to the reproduction head.Type: GrantFiled: December 19, 1997Date of Patent: October 19, 1999Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Hiroshi Yoshiya, Atsushi Hojo
