IPC: G11B5/17
Filed: 1999-06-02
Abstract: PROBLEM TO BE SOLVED: To reduce the man-hour in manufacturing or assembling of a gimbal spring and to improve the followup ability of a magnetic head to a floppy disk. SOLUTION: In a magnetic head device used in a floppy disk drive, a part of the conductive gimbal spring 2 itself constituting the magnetic head device is formed into a wiring pattern 4, and moreover an insulating material 6 such as resin and the like having flexibility is filled into the gap between the wiring pattern 4 and the gimbal spring 2. Thus, the man-hour in assembling is reduced because a parallel pair cord is not required and the followup ability of the magnetic head 1 is also improved because rigidity of the gimbal spring 2 does not become high.

Title: Dispersion compensating fiber and its manufacture
Inventor: AKASAKA YOUICHI
IPC: G02B6/036
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of polarized wave dispersion by setting the germanium concentration change in the circumferential direction of a center core circumference situated in the center part of a quartz glass core to a specified value or less by the value of specific refractive index difference. SOLUTION: This dispersion compensating fiber is formed of a quartz glass core having germanium added thereto and a quartz glass clad having fluorine added thereto on the outside of the core. The profile of refractive index distribution of the dispersion compensating fiber has a structure in which a center core 1 having the highest refractive index is surrounded by a clad 2 having a low refractive index. The change of germanium concentration in the circumferential direction on the core circumference is set to 0.05% or less by the specific refractive index difference. Thus, double refraction of the core caused in spinning can be reduced, and the polarized wave dispersion value resulted from the double refraction of the core can be reduced to 0.1ps/ (km) '-"" to perform a large capacity light transmission of high quality.

Title: Transmission control system of loop network
Inventor: NAKAI SHOICHIRO
IPC: H04Q11/04
Filed: 1984-07-26
Abstract: PURPOSE:To keep the code error produced on a transmission line within the period and to bring the state to the normal state from the next period by allowing a trigger station to interrupt the transmission line until the start time of the next prescribed period when the station detects a signal succeeding to a synchronizing signal circulated through the transmission line. CONSTITUTION:An output 4-1 of an access control section 4 of the trigger station TS20 keeps an active state until the synchronizing signal is returned throug through the transmission line 24 and when an LED detection section 2 detects the end delimiter of the own synchronizing signal, the control section 4 resets the output 4-1. Then a switch 1-1 is connected to the transmission line 24 and a signal succeeding to the synchronizing signal is bypassed to an adjacent node station NS. When the detection section 2 detects the end delimiter of the packet transmitted from each station NS and a loop supervisory section detects the idle state after passing of the end delimiter, an output of an AND gate 9 is activated. The control section 4 activates again the output 4-1, the switch 1 is connected to a selector 7 to allow the selector 7 to select a POL register 11 via an output 4-2 so as to transmit a polling signal.

Title: Video reproducing device
Inventor: SATO TAKAHARU
IPC: H04N5/94
Filed: 1987-06-23
Abstract: PURPOSE: To obtain the nearly same signal as the reproduced signal of a case that a reproduction defect does not occur, and to maintain the continuity of a picture, even if a reproduction error is generated by substituting a normal signal, stored in a memory immediately before the reproduction error is generated, at the time of the reproduction error.  
     CONSTITUTION: When it comes a period (n+1) and the reproduced signal is not yet obtained from a rotary head 12, a reproduced output detection circuit 24 outputs a reproduction error signal. Then, a memory control circuit 28, as responding to this error signal, turns a video memory circuit 26 into a read mode, and makes the circuit 26 output the normal video signal of the period (n). Simultaneously with it, it outputs a switching signal, and switches an analog switch 30 to the output side of the circuit 26. Hereafter, the circuit 26 is made into a write operation state, and the normal reproduced signal is written, during the periods (n+2), (n+4), (n+6), during which the normal reproduced output is obtained from the rotary head 10, and for the periods (n+3), (n+5), (n+7), which are the time of the reproduction error, the signal, written in the circuit 26 during the just before period, is read out. The normal reproduced output is obtained by the operation switching of the circuit 26 and the switching of a switch 30.
