Abstract: PURPOSE: The titled emulsion that is made by adding an anticarcionogenic agent to an oil base containing colloidal magnetic fine particles and by dispersing the base liquid in water, thus permitting the intravascular administration and the guidance of the anticarcinogenic agent to the cancer site.  
     CONSTITUTION: An anticarcinogenic agent such as 5-fluorouracil is included in an oil base containing colloidal magnetic fine particles such as ferrite fine particles and the resultant liquid base is dispersed in water to form an O/W type emulsion. Or anticarcinogenic agent is included in an aqueous base of the colloidal magnetic fine particles and they are covered with an oil or with an oil containing the anticarcino- genic agent and the resultant oil drops are dispersed in water to form W/O/W type emulsion, thus producing the titled emulsion.

Title: Measuring apparatus of constriction of test piece
Inventor: MASUSE HIDEO
IPC: G01B11/16
Filed: 1989-06-30
Abstract: PURPOSE:To correctly measure the constriction by optically detecting the size of said constriction of a test piece after said test piece is broken with a predetermined pitch in a longitudinal direction thereby to obtain the minimum size of said constriction irrespective of the breaking shape of said sample piece. CONSTITUTION:When a laser beam oscillator 11 and a photodiode 12 are moved by a motor 20 relatively to the constricted part of a test piece 10 after it is broken with a predetermined pitch in a longitudinal direction, a size operating means 101 operates the size of the constriction every pitch based on an output signal from the photodiode 12. The sizes of the constrictions are sequentially latched into a comparison circuit 17. The comparison circuit 17 compares the size of the constriction previously operated with the size of the constriction instantly operated. At the same time, the comparison circuit 17 determines whether the difference is within a preset value. The minimum value of the size of the constriction within the set value is selected to be the size of the constriction when the test piece is broken. Based on this selected size of the constriction, the constricting ratio of the test piece after it is broken is calculated at 19. Accordingly, regardless of the breaking shape of the test piece, the size of the constriction thereof can be correctly detected.

Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To provide a cylinder which is excellent in operating characteristic while carrying out miniaturization. SOLUTION: Circumferential grooves 12, 13 are arranged on the outer peripheral side of a piston main body 5, and an annular packing 11 is mounted on the circumferential grooves 12, 13. The packing 11 is formed in a cross sectional nearly L-shape composing a base part 14 and an outer peripheral lip part 15 which extends from the base part 14. The groove widths of the circumferential grooves 12, 13 are formed in the width of such extent that the base part 14 is housed, and the base part 14 is formed in such constitution that an outer peripheral lip part 15 top end in a condition mounted on the circumferential grooves 12, 13 and a piston 5 main body end surface are positioned on the same position in relation to the thickness direction of the piston 5.  The thickness of the piston 5 is sufficiently formed thinly comparing with the case that an U-packing is used, and thereby, it is possible to carry out downsizing of the piston 5 so as to carry out downsizing of a cylinder. Since the packing 11 is a lip packing after all, friction resistance between a cylinder tube inner circumferential surface 2a and the packing 11 is reduced, and also operating characteristic after pressure leaving is improved.
