Abstract: PURPOSE:To reduce the write-station of other track than a target track by grounding one end of at least one write/read coil in two write/read coils through a resistor. CONSTITUTION:As for one write/read coil 11 in two write/read coils 11, 12, one end thereof is grounded through a resistor. To the center taps of these two read/write coils 11, 12, a DC voltage is always applied. Also, to one end of the write/read coil 11 wound round to a magnetic core 9 of narrow track width, a ground resistance 1 for minute current electric conduction is attached. That is, to the magnetic core 9 of narrow track width, a minute DC current magnetic flux is always flowing, and its direction is set to the direction for negating DC magnetic field receiving from a step-motor, etc., of a floppy disk device. In such a way, a write-station of a magnetic recording medium caused by an inflow of a magnetic flux is eliminated.

Title: Composite type magnetic bubble memory element
Inventor: KODAMA NAOKI
IPC: G11C19/08
Filed: 1985-10-09
Abstract: PURPOSE:To stabilize a transfer characteristic in case a rotating magnetic flux is small and element temperature is low by forming an area where a bubble holding film is thick in an area where ion is implanted in the vicinity of a connection part between an ion implantation transfer path and those of other transfer means. CONSTITUTION:The pattern of the ion implantation transfer path is generated with a photoresist, etc., and a thick ion implantation layer 3 is generated with said pattern as an ion implantation mask. Then the ion implantation mask is removed, and the area from which a magnetic bubble holding film is not removed is covered with a photoresist, after which the magnetic bubble holding film is scraped by ion milling. Next, the photoresist is removed, and ion is shallowly implanted on the overall surface of the magnetic bubble holding film 4, whereby the ion implantation layer for suppressing a hard bubble is generated. In such a way the ion implantation layer is made thin in the vicinity of the connection part to weaken the influence of in-surface magnetization. Even if the connection part has a small rotating magnetic field, and the element temperature is low, the reduction in a bias magnetic flux margin can be prevented.

Abstract: PURPOSE:To determine always correct exposing time regardless of the variance in the transmittance between samples by detecting the change with time of transmitted light and determining the time when the change rate with time attains a prescribed value or below as the completion of exposure. CONSTITUTION:The light 24 irradiated to a glass substrate 21 passes a mask 22 and is partly absorbed by a photosensitive resin film 23 in contributing to chemical reaction. The light 25 transmitted therethrough enters a photodetector 26. An optical disk 26 is connected to a recorder 27 and the change of the light 25 with time is recorded, by which the saturation point of the light 25 is known. The sample 32 is irradiated by a light source 31 and the light transmitted therethrough is converted by a photodetector 33 to an electric signal which enters an amplifier 34. The output thereof is differentiated by a differentiating circuit 35 and is compared with the preset change rate of the transmitted light with time by a comparator 36. The completion of exposure is determined when the output is below said change rate. A control signal for the light source is then fed to a light source 37 for an exposing machine to shut off the light source 31.
