A direct-current motor incorporates a permanent magnet system mounted on the motor shaft, a fixed armature winding mounted on a former consisting of two shell-like parts having means for fixing the two parts together, the motor shaft being mounted in bearings associated with the former, and a magnetic return path surrounding the former. Preferably, the former is drum-shaped and consists of two identical parts 5, one of which is shown in Fig. 2. Preferably, the complete former has four fins 12, two of these being formed by the juxtaposition of fin portions of less thickness lying in the plane of contact. Each part 5 has a boss-like extension 7 cupped at its inner end for reception of a bearing 4 (see Fig. 1). The bearing is then held in place by fitting of a spring 8, Fig. 1, gripped behind a projection 9 formed integrally with part 5. Next, the rotor with permanent magnet 3 is assembled with the parts 5 by pushing its shaft 1 into the bearings, after which the two parts 5 are joined together, using dovetail extensions and slots 17. Then the component windings 13, 14 of one phase are applied to the former by bi-filar coiling, and then the component windings 15, 16 of the other phase are applied at right angles thereto. The magnetic return path 23 consists of annular laminations which are pushed on to a mandrel (to define subsequently a smooth interior), the assembly being then located in a casing 22, and the casing being deformed at 24 to secure the discs together; the mandrel is then removed. Some of the annular laminations at one end of path 23 have openings forming two recesses 30 spaced 90 degrees apart, in each of which is later disposed a Hall generator 31 (one for each half of the stator winding). Each Hall generator is secured to a baffle plate 32, itself secured to a disc support 21, and a closure disc 27 is applied. Then the stator-rotor assembly is introduced into the casing, and lugs 18 on fins 12 are engaged in apertures 19 in support 21. Finally, disc 20, also having apertures 19 for engagement with lugs 18, is pushed on. Oil-impregnated discs 10 are provided for the bearings. Connecting tags 26 emerge from discs 21, 27.

Title: Magnetic tape unit reading system

Filed: 1970-12-08
Abstract: 1336150 Digital data storage FUJITSU Ltd 8 Dec 1970 [8 Dec 1969 23 Dec 1969] 58339/70 Heading G4C Bytes containing all 1 and all 0 bits read from a magnetic tape are detected and are regarded as a data block postamble to start a measured time interval in which the presence of other than all 0 bytes is looked for, before the detection of the postamble is confirmed. The bytes read are passed through a shaper 11, deskew register 12, read register 13, correction circuit 14 and data register 15 to a processor via OUT 1. The presence of all 1 and all 0 bytes in registers 15, 13 is recognized at 27, 20 respectively, and their simultaneous recognition produces an output from postamble start detector 17 to set a bistable 18, after which each byte read is counted at 19. An end data checking circuit 21 provides outputs if a non-zero byte is detected before counter 19 has counted to a predetermined number, to set an adding circuit 24 to + 1 and, in conjunction with the output of a drop-out detector 16 passed through circuit 22, to signal the processor via OUT 2 that a data error has occurred. Before initiating a re-read of the data block, the processor sets circuit 22 according to the track in which an error occurred and sets circuit 23 to represent the number of times the postamble has been mis-detected. Data for this purpose being transmitted to the processor in succession from circuits 21, 22 and 24. During the re-read the postamble start corresponding to the previously mis-detected postamble start is ignored and any further mis-detested postamble start is treated in a similar manner. When byte counter 19 reaches a predetermined count signifying that a predetermined number of all zero bytes has been detected following a postamble start, the detection of the postamble is confirmed.
