摘要： An optical fiber connector for connecting an optical fiber cable to a ferrule comprises a tubular body having a first end portion for connection to a peripheral surface of a ferrule, a second end portion for connection to a peripheral surface of an optical fiber cable, a step portion interconnecting the first end portion to the second end portion, and a clamping portion for clamping the optical fiber cable to the ferrule. The clamping portion extends inwardly from a terminal end of the second end portion towards the central axis of the tubular body but does not project lengthwise from the terminal end of the second end portion in the direction of the central axis. The first end portion, the second end portion, the step portion and the clamping portion of the tubular body have approximately the same wall thickness.

摘要： A liquid level detecting circuit is pattern-printed on a board. The liquid level detecting circuit has a pair of discharge elements and an electrostatic capacitance change detecting circuit. One of the discharge elements is grounded, and the other of the discharge elements is connected to a pipetting probe and the electrostatic capacitance change detecting circuit. When an extraneous noise signal such as a noise signal caused by static electricity charged on the surface of a container is input through the pipetting probe while the pipetting probe is being moved toward the container containing a liquid the liquid surface of which is to be detected, the extraneous noise signal is discharged to the ground through the pair of discharge elements to suppress the transmission of the noise signal to be transmitted to the electrostatic capacitance change detecting circuit. An inductance placed between the other discharge element and the electrostatic capacitance change detecting circuit promotes the discharge of the noise signal.

摘要： In a non-contact type tonometer for blowing compressed gas against an examined eye through a nozzle, when a piston returns to an initial position by a biasing unit for biasing so as to return the piston to the initial position, a piston driving unit is actuated so as to attenuate the piston return speed by applying a force in the upwardly moving direction. Further, the piston is attached a piston rod so as to move in the axial direction of a cylinder, and is provided a gas passage which is closed when the gas is compressed and is opened when the piston returns to the initial position by the movement of the piston rod. Thus, the air compression chamber within the cylinder is caused to conductively connect to the atmospheric open chamber to thereby restrain the interior of the cylinder from becoming negative in pressure. In this way, it is possible to suppress the sucking-in of tears, dust, eyelashes and the like through the nozzle as effectively as possible with a simple structure.

摘要： A method of polishing an end surface of an optical fiber comprises tilting the central axis of a ferrule integrated with an optical fiber at a preselected angle .THETA. to the axis of rotation of a flat polishing member. A foremost end of the ferrule is then moved into contact with a flat polishing member to polish the foremost end of the ferrule and an end surface of the optical fiber. The foremost end of the ferrule is moved out of contact with the flat polishing member after the ferrule and the optical fiber have been polished into a flat plane. The central axis of the ferrule is then tilted at the angle .THETA. to the axis of rotation of a platen and at an angle .theta.=.THETA.+.DELTA. to a line normal to the surface of the platen, where .DELTA. is an angle of tilt of the rotational platen relative to a flat support surface supporting the rotational platen. Thereafter, the foremost end of the ferrule is moved into contact with a second polishing machine to polish the ferrule and the optical fiber. The ferrule is moved out of contact with the polishing member after the ferrule and the optical fiber have been polished into an oblique convex spherical surface so that an oblique angle defined between a plane normal to the central axis of the ferrule and a tangent plane at the intersection of the central axis of the ferrule and the surface is equal to angle .THETA..
