Title: Head positioning circuit for magnetic disk device
Inventor: TSUKAGOSHI SHINICHIRO
IPC: G11B21/10
Filed: 1989-06-14
Abstract: PURPOSE:To stably perform positioning control by judging the position of a magnetic head with an absolute address counter, and varying the gain of a position signal with a variable gain amplifier by selecting an appropriate correction value with a read-only memory. CONSTITUTION:A track pulse signal 2, a forward signal 3, a reverse signal 4, and a reset signal are inputted to the absolute address counter 6 of a variable gain circuit 14, and the counter 6 judges the current position of the magnetic head, and outputs a correction value address signal 7 to select the correction value of the power constant of a voice coil motor. The read-only memory 8 receives the selection signal 7, and outputs the correction value of the power constant suitable for the current position of the magnetic head as a digital correction value signal 9. The correction value signal 9 is supplied to the variable gain amplifier 12 via a D/A converter 10, and changes the gain of the amplifier 12, and the position signal 1 is outputted as a correction position signal 13. Thus, the positioning control can be stably performed.

IPC: G11B7/09
Filed: 1980-10-25
Abstract: PURPOSE:To access a track exactly, by holding a condenser lens so that it can be displaced only in the direction for controlling a focus. CONSTITUTION:An optical head body 10 is constituted so that it is moved only in the direction for accessing a track against a head external housing 20, and a moving body 13 is also constituted so as to be moved only in the direction for controlling a focus against the optical head body 10. Movement of the optical head body 10 and the moving body 13 is controlled by electromagnetic coil part 14, 19 and magnets 17, 21, respectively, therefore, no unnecessary vibration is generated, and its control is executed easily. Also, a light beam irradiated to the disk is moved in parallel with the direction for accessing a track, therefore, its position is detected easily. Furthermore, since the direction of the light beam is diverted by 90 deg. by a mirror 18, dimension of the direction for controlling a focus is made small.

SOLUTION: A connecting port 43 of a thread sucking pipe 34 is formed with a gradient, and an insert part 44 is connected with a gradient to the thread sucking part 34. The connecting port 43 is provided with an opening and closing cover 51 for opening and closing an insert hole 50 to be freely rotated, thereby closing the insert hole 50 when the insert part 44 is not connected thereto, and engaging with a flange 44a when it is connected to keep the insert part 44 from being slipped out. First, the opening and closing cover 51 of the connecting port 43 is opened, the insert part 44 is connected thereto, and an air hose 35 is also connected to a connecting part of an air supply pipe 36. In such a condition, sucking force is generated in a suction pipe 40, thereby sucking the thread from the connecting port 43 obliquely to the thread sucking pipe 34. Accordingly, even if the thread collides in the thread sucking pipe 34, it collides with the pipe obliquely to a sucking flow, and the movement component remains toward the sucking flow so as to prevent the thread from staying in the connecting port 43.

Title: Glass fiber for optical transmission
Inventor: OISHI KAZUMASA
IPC: C03C25/24
Filed: 1992-05-20
Abstract: PURPOSE:To obtain the thinly coated optical fiber which can maintain the side pressure resistance characteristic, light transmission characteristic and fiber strength equal to or better than the side pressure resistance characteristic, light transmission characteristic and fiber strength of the conventional coated fibers by specifying the Young's modulus and elongation of a UV curing type resin to be used for the outermost layer to specific values or above. CONSTITUTION:This glass fiber has at least two-layered structures in terms of reduction in thickness and is provided with a protective layer 3 via a buffer layer 2 on the outermost layer of the glass optical fiber 1. The resin having >=100kg/mm<2> Young's modulus and >=30% elongation is used as the UV curing type resin constituting the protective layer 3 of the outermost layer. The protective layer 3 of the outermost layer plays the role of a shell for protecting the glass against external pressures The protective layer is eventually stronger to the external pressures as the Young's modulus is higher. On the other hand, the protective layer is brittle to bending and is apt to break if the elongation characteristic is small. The side pressure resistant characteristic of particularly the thinly coated fiber (<=200mumphi coating outside diameter) is maintained at >=100kg/mm<2> Young's modulus and >=30% elongation, by which the light transmission characteristic is improved.
