A system for burning a liquefied gas comprises a burner gun for spraying the liquefied gas into a combustion space, a pump for feeding the gas under pressure, pipe means connecting the burner gun with the pump, and a flow regulating valve provided in the pipe means, wherein the portion of the pipe means downstream from the valve has its inner diameter so determined in relation with the flow rate of the gas that the state of the gas flow through said portion falls within fog flow zone or bubble flow zone on Baker's two-phase flow diagram. In the system of the invention, unstable combustion of the liquefied gas due to vapor lock in the pipe means can be prevented even when the gas supply pressure is below the vapor pressure of the gas. Besides, the calorific value obtained with the system is variable over a wider range than with a conventional system. Thus the system has a remarkable industrial value.

A centrifuge includes a frame, a door, a restricting part, a first spring member, and a second spring member. The frame has an opening on top thereof, when the frame is disposed in an orientation in which the frame is intended to be placed. The door is movably supported on the frame to be capable of opening and closing the opening. The restricting part is provided on the frame and defines a prescribed region. The first spring member has one end pivotally supported on the door, and another end pivotally supported on the frame. The second spring member has one end pivotally supported on the door, and another end that is movable within the prescribed region.

In a centrifuge comprising a rotor mounted on a drive shaft to be rotatable and having a plurality of bucket accommodating portions and a plurality of buckets placed in the bucket accommodating portions to be swingable, a plurality of sensors are provided to detect each of the buckets. In a case in which each of the sensors does not the bucket when the rotor is in a stop condition or in a low-speed rotation condition, a decision is made that an abnormality of a swinging movement of the bucket has occurred, and the fact of the occurrence of the abnormality is notified to a user. This allows abnormal conditions of the apparatus to be detected, thus protecting a sample and apparatus and enabling the maintenance of the apparatus in advance.

An automatic centrifugal machine comprises a handling apparatus for shifting a test specimen from a predetermined position, a rotor equipped with a bucket accommodating the test specimen, a drive motor for rotating the rotor, a chamber surrounding the rotor, and a refrigerator for cooling the chamber, and the automatic centrifugal machine has a height equal to or less than 1,450 mm. A conveyor line, conveying the test specimen, has a height in a range from 750 mm to 850 mm. The handling apparatus of the test specimen is formed by a link arm mechanism including first and second sliders, first and second arms, and a manipulator hand. The manipulator hand is shifted by controlling first and second sliders so as to satisfy the following relationship Bx = x1 - L2 2 - [ L1 sin { cos - 1 ( x1 - Ax L1 ) } + d ] 2 where “L1” represents the length of a first arm, “L2” represents the length of a second arm, “d” represents the clearance between the arm pivot axes on the first and second sliders, “Ax” represents the position of the first slider in the sliding direction and “Bx” represents the position of the second slider in the sliding direction, and “x1” represents the position of the shift member in the sliding direction.
