Title: Composite magnetic head and its production
Inventor: TAMURA TEIZOU
IPC: G11B5/23
Filed: 1982-09-22
Abstract: PURPOSE:To mass-produce easily composite magnetic heads having high accuracy, by forming plural specific recessed grooves to a counter surface of a center core block to a recording medium. CONSTITUTION:The recessed grooves 11 are formed with a sloping cross to the ridge line of the gap forming surface by an angle theta (about 10-45 deg.) and a pitch P to a counter surface of a center core block 6 (including ferrite plates 4 and 5, a nonmagnetic thin plate 3). Thus many pieces of groove parts 20 are formed with depth D larger than the gap depth GD, and an area having the width equal to the track width TW1 in the direction of gap forming surface is left between parts 20. Then C core blocks 7 and 8 are brought into contact with the gap forming surface of the block 6 via a nonmagnetic thin film, and these blocks and the gap forming surface are joined together by filling glass, etc. into the part 20. This unified block is cut at a cutting line shown by the arrow mark. Thus it is possible to produce a composite magnetic head containing a read/write head having a track of width TW1 and an erasion head having a track of width TW3.

Title: Rotary tape guide of magnetic recording and reproducing device
Inventor: SASAKI TAKASHI
IPC: G11B15/61
Filed: 1993-07-05
Abstract: PURPOSE:To stably run a magnetic tape by making the circumferential speed of a tape guide different from the running speed of the magnetic tape. CONSTITUTION:The rotary tape guide 11 of the supply side held by a rotary shaft holder 50 and a height setting flange 18 are arranged in the upper part of a moving base 17. The rotary shaft 56 of a driving source is freely rotatably held by the base 17 and a bearing of a holder 51, and the rotary tape guide 11 of the supply side is force-fitted into the rotary shaft 56. A main shaft of the flange 18 is erected on the base and the height is adjusted by a cap in the part and a pressed spring. The same arrangement is provided also for a rotary tape guide on the take-up side. When the tape guide 11 and the tape 7 are moved relatively at different speeds, a force D working in the breadthwise direction of tape is smaller than a static friction force C. When the tape guide 11 is rotated in the direction of the arrow at a high speed, an air layer is formed between the tape 7 and the guide 11, and the tape load is not increased. Thus, a contact load between the magnetic tape 7 and tape guide is eliminated and the unnecessary increase of tension is prevented, thereby the tape is made stably to run.

IPC: H01R39/04
Filed: 1988-07-01
Abstract: PURPOSE:To facilitate the mounting work of a commutator and to provide the rigid commutator by forming a ring for clamping commutator segments in a coil having spring characteristics. CONSTITUTION:When a commutator 1 is assembled, commutator segments 4 and insulators 7 between the segments are alternately associated to be arranged in a cylindrical state, and a coiled ring 8 is mounted in a recess 5. In this case, the insulators 7 between the segments are so formed in a shape that the segments 4 are not brought into contact with the ring 8, and so formed as to reduce an interval to the ring 8 as short as possible to prevent the ring 8 from dropping. When the ring 8 is mounted, it is easily mounted since the ring 8 has spring characteristic and its outer diameter can be regulated by its elongation or contraction. After it is mounted, it is strongly clamped by its recoiling strength, and its rigidity can be hence maintained.
