Title: Optical amplifier
Inventor: ISSHIKI KUNIHIKO
IPC: H01S3/06
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To obtain an optical amplifier which has low-noise characteristic through three-level excitation and is satisfactory in gain flatness by pumping a fluoride glass optical fiber, in which at least both Er ion and Yb ion are added in a core, at an pumping wavelength of a specific band and amplifying the inputted signal light of a specific band. SOLUTION: A pumping light of 1.02 μm band of a wavelength outputted from a 1.02 μm-band pumping light source 2 passes through an optical fiber 5 and an optical coupler 3 and enters an EYDF (Zr-based fluoride glass optical fiber 1 added with both Er and Yb ions) 1. The pumping light excites the Yb ion, and the Er ion is excited due to the movement of energy, thereby optical amplification action is given to 1.5 μm-band input signal light. Namely, the Er ion is excited in three levels by the 1.02 μm-band pumping light through the Yb ion. Therefore, the population inversion is formed in the EYDF1 by inputting the 1.02 μm-band pumping light, and low-noise property is made possible.

IPC: G11C11/14
Filed: 1981-11-09
Abstract: PURPOSE:To simplify a control circuit and write continuous data easily by placing a conductor pattern for erasing and generating bubbles on a specific position of a magnetic bubble transferring pattern and erasing/generating bubbles in the same rotating magnetic field period. CONSTITUTION:After adding a rotating magnetic field shown in (b) to a bubble transferring pattern 1, a bubble is transferred. When the rotating magnetic field is set to ''2'', pulse current is applied to a bubble erasing pattern 2 to strengthen the bias magnetic field and erase the bubble. When writing data is ''1'', pulse current is applied to a conductor pattern 3 to the direction to weaken the bias magnetic field when the direction of the same rotating magnetic field period is ''4'' to generate a bubble. A weak magnetic field for absorbing the bubble is applied by using only the conductor 3 and then pulse current may be made flow so as to apply a bubble erasing magnetic field at the writing data of ''0'' or a bubble generating magnetic field at ''1''.

Title: Information recording medium
Inventor: KAMISADA TOSHIMASA
IPC: G11B7/24015
Filed: 1982-10-15
Abstract: PURPOSE:To prevent adverse effect on a recording and reproducing signal because of birefringence, by providing a stress absorbing section to a spacer and absorbing the expansion and contraction due to temperature change in the spacer to reduce the stress produced in a disc. CONSTITUTION:A base 3 provided with a recording member 2 on a disc 1 is bonded to other base 3 via inner and outer circumference spacers 4, 5. Eight pits 7 are provided to the inner circumference spacer 4 in addition to a center section 8. The inner circumference spacer 4, the center section 8 and an outer circumference 9 are linked with a beam 10 through the pits 7. When the thermal expansion coefficient between the inner circumference spacer 4 and the disc 1 is different and the thermal expansion coefficient of the inner circumference spacer 4 is larger than that of the disc 1, the inner circumference spacer 4 generates a stress spreading the disc 1 toward the outer circumference as temperature rises, and birefringence is produced in the disc 1. Since the beam 10 deforms as shown in broken lines, the stress at the center section 8 is absorbed by the beam 10 and becomes very small, and the stress applied to the disc 1 is reduced remarkably.
