Filed: 1986-03-20
Abstract: PURPOSE:To enable multiple carriers to perform transportation at the same time by implementing the transport with a carrier divided into two and more in the case the carrier route is overlapped among multiple carriers. CONSTITUTION:A carrier CR 1 transports from the position ST 1 of a stator 4 to that of ST 5. On the other hand, in the case a carrier CR 2 transports from a position ST 4 to a position ST 7, it is recognized to a linear motor controller 2 that the carrier route of the CR 1 overlaps that of the CR 2 between ST 4 and ST 5 of the stator 4. The transport of the carrier CR 1 is therefore divided into two transports: ST 1-ST 3 and ST 3-ST 5; the transport of ST 1-ST 3 of the CR 1 and that of ST 4-ST 7 of the CR 2 are carried out at the same time. The moment the CR 2 passes ST 5 when the CR 1 gets to the position ST 3, a carrier control is carried out again from the position ST 3 to that of ST 5.

Title: Magnetic disk, magnetic recording and reproducing method, and magnetic disk apparatus
Inventor: UNO KOJI
IPC: G11B5/56
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To increase a recording density without reducing an S/N ratio of reproduced signals by overlapping a first recording region, having a track for recording at an azimuth angle equal to a prescribed value or less, with a track adjacent to a second recording region, having a track for recording at an azimuth angle equal to the prescribed value or more, by a value corresponding to a radius or more and setting respective track pitches at different values. SOLUTION: When an actuator 1 rotates around a point O, respective angles between a head H and tracks T1-T3 on a magnetic disk 100 are different from each other based on a position of the head H on the magnetic disk 100. By setting a track pitch at an inner peripheral portion A on the magnetic disk 100 at a smaller value than that at an outer peripheral portion C and setting an effective track width at a sum of a width of a read head and a width of a dead space, adverse influence of crosstalk from an adjacent track is suppressed. At an intermediate portion B on the magnetic disk 100, a satisfactory S/N ratio of signals can be retained and a recording density can be improved even when a track pitch at that portion is set at a smaller value than that at the outer peripheral portion C.

Title: Rotating hook of sewing machine
IPC: D05B57/26
Filed: 1992-03-19
Abstract: PURPOSE:To reduce frictional resistance of a contact surface between a rotating hook bobbin case holder and a rotating hook so as to prevent seizure by forming a coating layer formed by nickel-phosphorus or a nickel-phosphorus-polytetrafluoroethylene on the surface of a rotating hook of a sewing machine. CONSTITUTION:A rail groove 11 guided by a rail 2 of a rotating hook bobbin case holder 7 is formed on the inner periphery of a rotating hook bobbin case holder 10. A storing chamber 12 for storing a rotating hook bobbin case holder 1 is formed in a rotating hook 10. A coating layer 13 formed by Ni-P is formed on the inner periphery of the rotating hook 10 including the rail groove 11. As the frictional resistance of the outer peripheral surface of the rotating hook 10 is lowered, the removal of a needle thread in a shuttle locking area can be facilitated, and the frictional resistance between the rotating hook bobbin case holder and the rail is lowered so as to rotate the rotating hook at high speed. Thus, the sewn product manufacturing speed can be improved. On the knifeedge, the friction with the needle thread is lowered to improve the smoothness of thread threading area, and at the time of overrun of thread, undesired tension is not applied to the thread bobbin so as to improve the quality of sewing. At the time of forming the coating layer 13 formed by Ni-P on the surface of the rotating hook 10, it is dipped in a hypophosphite bath to perform electroless plating.

Abstract: PURPOSE:To reduce falling shock at supplying microplates, and prevent lifting again of the supplied plates by providing the opening/closing operation part of two claw parts by which microplates in the laminated condition are supported from the lower side in their closed condition and released in their opened condition. CONSTITUTION:By descent of a stocker 18, claw parts 20 begin opening motion by collision of the extreme ends against the inclined plate parts 22 of a plate carrier 14. At this time, microplates 16 on the lowermost step are nearly close to the upper face of the carrier 14, and hence a shock is not generated at detaching the claw parts 20. As the descent progresses, positional relation of two supporting points 24a, 24b of two supporting point spring 24 is changed, and the claw part 20 is changed from enegization in the closing direction to energization in the opening ditrection. Next, when the stocker 18 is elevated, the claw part 20 is elevated in the opened condition, run against a fixed arm 28, and rotationally moved in the closing direction. Hereby, the spring supporting point 24a is returned to the original position, and the claw part 20 is energized in the closing direction. At this time, there is no such apprehension once placed lowermost microplate 16 is locked again by the claw part 20.
