Title: Optical fiber loss adjustor
Inventor: FUNAHASHI MASAAKI
IPC: G02B6/00
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To adjust the loss of an optical fiber with simple constitution. SOLUTION: This loss adjustor is composed of a fiber fixing substrate 1, a press cap 2 and a fiber or array fiber 3. Coating of a middle part is removed, and glass of a fiber is exposed to be placed on the fiber fixing substrate 1. The fiber fixing substrate 1 is performed with groove 4 processing on the central part of the fiber fixing substrate so as to be orthogonally intersected with the longitudinal axis of the fiber when the fiber is placed. Heating is used for adjusting the loss. By heating the fiber, the fiber is melted, and a bend occurs in a linear fiber, and an optical loss occurs. When the fiber is adjusted once, the loss is stabilized permanently. Since an attenuation membrane and a filter, etc., aren't inserted into the optical path of the fiber, reliability is improved.

Title: Drive system for magneto-resistance effect head
Inventor: FUKUOKA HIROTSUGU
IPC: G11B5/39
Filed: 1986-11-21
Abstract: PURPOSE:To attain the long service life of a magneto-resistance effect head by supplying an intermittent electrical signal to the magneto-resistance effect head so as to suppress the temperature rise of the magneto-resistance effect head. CONSTITUTION:Conductive terminals 12, 14 are connected across the magnetic thin film 10 formed by the magneto-resistance effect element and an electrical signal from terminals 20, 22 is fed to the terminals 12, 14 via leads 16, 18 respectively. A resistor 24 is inserted on the way of the lead 16 and an output voltage of the magneto-resistance effect head is generated from the terminals 26, 28 connected across the resistor 24. Since a pulse signal is fed to a magnetic thin film 10, the Joule's heat is reduced in a rate of time means of a/(a+b) more than the case with a signal of a prescribed voltage supplied to the magnetic thin film 10. Thus, the temperature rise of the magnetic thin film 10 is reduced and the thermal noise is decreased to prevent melt-down of the magnetic thin film 10.

The temp. of the sputtered film is raised from 280 deg.C-800 deg.C at the rate of about 2-20 deg.C/min. The heating temp. is regulated to <=500 deg.C in the case of an Al substrate, and adjusted to about 800 deg.C in the case of a ceramic substrate. The sputtered film is kept at the temp. for 10min-20hr to deoxygenate the film. The necessary time is adjusted from long to short as the heating temp. is changed from low to high. A magnetic field is impressed in the direction parallel to the direction in which the medium is used in the surface of a magnetic film which is kept at the heating temp. In the case of a magnetic tape, a magnetic field is impressed in the traveling direction of the tape, and a magnetic field is impressed in the circumferential direction in the case of a magnetic disk.

Filed: 1985-12-11
Abstract: PURPOSE:To increase the stability and efficiency in laser machining by providing the control means which adjusts the laser output by setting the nugget diameter of the body to be worked to the reference nugget diameter. CONSTITUTION:The outgoing laser beam from a laser oscillator 1 is condensed by a laser machining part 2 and projected on the body to be worked.
