Title: Displacement sensor
Inventor: ISOI TOSHIMITSU
IPC: G01C3/06
Filed: 1990-05-28
Abstract: PURPOSE:To confirm the emission of laser even at a place which is subject to the exposure to the laser emission by providing a mark display device which indicates the positions of both ends of the scanning range of a laser beam with optical marks of visible light on an object body before the specified time of the emission of the laser beam in synchronization with a laser-emission alarming lamp. CONSTITUTION:A light projecting lens 23 is used for converting the light from a laser 21 into the parallel light ray. A mirror 24 is provided to decrease the restriction on the relationship of the arrangements of the laser 21 and a scanning mirror 22. In a light projecting system 20, a laser beam is emitted on an object body 1 through a light projecting window 11 of a cabinet 10. The laser beam is made to scan on the surface of the object body 1 in response to the turning of the scanning mirror 22. A light receiving system 30 is formed of an optical system 31 and a one-dimensional position detecting sensor 32. The optical system 31 condenses the laser light which is diffused and reflected from the surface of the object body 1 and which is cast through a light receiving window. The detecting sensor 32 is arranged on the image focusing surface of the optical system 31. The position detecting sensor 32 is formed of PDS and the like. The output corresponding to the position of the spot of the condensed light which is formed on the image detecting surface of the optical system 31 is generated. The distance between the scanning mirror 22 and the object body 1 is obtained by a triangulation method based on the output of the position detecting sensor 32. Thus, the amount of displacement of the surface of the object body 1 is detected.

Title: Syringe type vessel
Inventor: NAGASAKI SHUZO
IPC: A61M5/315
Filed: 1994-05-30
Abstract: PURPOSE:To reduce remaining air to the possible minimum level when a medical fluid is injected into a cylinder, and prevent a return of a piston and liquid leakage even if air is left more or less by carving axial directional grooves on a cylinder inside surface, and installing a cap shaped or cylinder-shaped elastic body on the tip of the piston. CONSTITUTION:In this syringe type vessel, one or more grooves 7 are carved in the axial direction on an inside surface of a piston inserting port of a cylinder 1, and a cap-shaped or cylinder-shaped elastic body is installed in a piston tip part 8. When a piston is inserted from a diametrically expand part 5 of the cylinder 1, air existing on a content liquid 10 passes through the grooves 7, and is discharged from this syringe type vessel. When the piston is deeply inserted, it passes through a projection 6. In this condition, a groove 7 lower part is brought into close contact with an outer periphery of the piston tip part 8, and the grooves 7 are perfectly cut off from the content liquid. At this time, though most air is discharged, since still remaining air exists, even if the pressure acts so as to return the piston, the projection 6 prevents the return of the piston.
