Title: Magnetic bubble memory device
Inventor: HIROSHIMA MINORU
IPC: G11C11/14
Filed: 1989-05-19
Abstract: PURPOSE:To enlarge a common bias magnetic field operating area and to obtain the stable transfer characteristic of magnetic bubble by employing an asymmetrizing means into an ion injection transfer path. CONSTITUTION:The asymmetrizing means is provided to relieve difference between the right and left bias magnetic field margins of a magnetic bubble transfer path and preferably, as the asymmetrizing means, a cross angle is provided between the triaxially symmetric crystal shaft direction of a magnetic bubble magnetic film, to which ion is injected, and a magnetic bubble transfer direction. The means to asymmetrize the transfer path is a parameter to strong ly affect the bubble transfer of the ion injection transfer path and an unbalanced state of the right and left bias magnetic field margins of the transfer path can be reduced. Thus, the common bias magnetic field operating area can be enlarged and the stable transfer characteristic can be obtained.

Title: Sample-component preparative isolation apparatus
Inventor: KIKUMOTO MAMORU
IPC: G01N1/10
Filed: 1991-04-25
Abstract: PURPOSE:To prevent the effects of the deviation of holding time and the like by alternately setting a time zone, wherein a peak is detected, and a time zone, wherein the peak is not detected, with the specified peak on a chromatograph as a starting point, and performing the preparative isolation during the period when the peak is detected in the time zone, wherein the peak is detected. CONSTITUTION:T0 is the time when a sample is injected into a chromatograph. P1 is the specified peak. L is the peak judging level. It is judged that there is the peak during the period wherein the detected output is at the L level or higher. The detected output exceeds the level L at the rise-up side of the peak P1. A time schedule B starts at the time T1. A shaded region E indicates the time zone, wherein the peak detection is performed. A blank region N indicates the time zone, wherein the detection is not performed. The second peak P2 is the peak, which has appeared in the time zone where the peak detection is not performed. Therefore, no action is taken. The third peak P3 is located in the time zone, wherein the peak detection is performed, and the detected output exceeds the level L. Therefore, a valve is switched for the period S, and the component is separately accepted. Since the next peak P4 does not reach the level L, the preparative isolation is not performed.

Filed: 1991-04-25
Abstract: PURPOSE:To correct aberration change in good performance by forming both No.1 and No.2 lens groups with variable refractive power lenses, which can move on the optical axis and have variable refractive powers. CONSTITUTION:A built-in extender lens EX consists of an afocal system of two lens groups, No.1 group I having a positive refractive power and No.2 group II having negative refractive power. Both the No.1 and No.2 groups are movable on the optical axis, and each group has variable refractive power lens with the radius of curvature changeable, and thereby the total refractive power of each group can be changed. Therein the optical properties such as refractive power of the whole system as a built-in extender lens or refractive power arrangement are changed into various values by changing the principal point interval of No.1 group I and No.2 group II and the focal point distances (refractive power) of both groups.
