摘要： PURPOSE:To make it possible to perform automatic measurement of a deposition point in a short time by measuring the amount of transmitted light at the deposition point of a specimen, and obtaining deposition temperature and dissipating temperature. CONSTITUTION:A specimen whose deposition point is known is injected into a specimen chamber 11 of a measuring cell 10 and stored. Light is inputted into the specimen from a light source 35. The amount of the transmitted light at the deposition point is detected with a photodetector 36 through an optical fiber 34. The detected amount of the transmitted light is used as a judging point and stored in the memory in a control part 40. Then, the specimen whose deposition point is known is discharged, and a specimen whose deposition point is unknown is injected and stored in the specimen chamber 11. Cooling and heating are performed, and the light is transmitted. the control part 40 stores the specimen temperature when the amount of the transmitted light becomes the same amount at the judging point during the continuation of cooling as deposition temperature. The specimen temperature when the amount of the transmitted light becomes the same amount at the judging point during the continuation of heating is stored as dissipation temperature. Then, cooling and heating are repeated. When the difference between the deposition temperature and the dissipating temperature becomes a value within the specified value, the dissipating temperature at this time is determined as the deposition point.

摘要： PURPOSE:To distribute efficiently various kinds of liquid specimens into various kinds of containers and to automate work for weighing the distributed specimen accurately. CONSTITUTION:A transfer part 50 takes out a specimen container grasped by a grasping part 90 from a container storage part 5 and transfers the container to a weighing part 27 by moving it in X, Y, or Z direction. The weighing part measures the weight of the vacant specimen container, and the container is sent to a specimen supply part 20 by the transfer part. The specimen supply part feeds a specified fluid specimen to the container. The transfer part transfers the container with the specimen again to the weighing part, where the weight of the container with the specimen is measured. The weight of the liquid specimen in the container is calculated from these values of weight. The container with the fluid specimen is returned by the transfer part to a specified position of the container storage part.

摘要： PURPOSE:To simplify quality control by irradiating light from a light projector on an intermediate fraction sample such as gas oil, detecting the state change with a decrease in the temp. of the sample by a photoelectric detector and drawing a process curve in the correlation with time and temp. CONSTITUTION:The intermediate fraction sample such as gas oil or fuel oil A is controlled in quality by a photoelectric method for automatic and continuous detection of the process cloud point, low temp., filter clogging point and freezing point. A vessel 2 contg. the sample 3 is fixed in a tank 1 in this stage and is cooled by an electric refrigerator 4, etc. to decrease gradually the temp. The light from a light source 5 is irradiated on the surface of the sample 3 and the reflected light is detected by the photoelectric detector 6. The condition in which the sample 3 solidifies gradually is displayed in correlation with time and temp. by a printer 8, etc. The vessel 2 is moved by a motor 9 and the pour point is detected from the way how the sample 3 moves. The continuous detection of the cloud point and clogging point and freezing point of the sample is thus made possible and the yield of the product is improved.

摘要： PURPOSE:To obtain a stable output even if rotation is changed, by using a conventional Bourdon gage, reading a value optically, obtaining the records of multiple channels for a long time, and electrically calibrating the pressure gage. CONSTITUTION:Modulated light from a light emitting diode 7a is projected on the surface of a pressure gage. The reflected light is received by a light receiving diode 7b. Then the signal is rectified by a rectifier 11 and wave form d-b is obtained. In this waveform, b1 is a judging mark, b2 is an original point mark and b3 is a light signal by a pointer. A time length (t) between b2 and b3 is a deflection degree of the pointer. Therefore, only b1-b3 can be taken out accurately. The detected signal is reset by a signal, which is obtained by delaying the judging mark by an FF in a delay circuit 18 using an original point and pointer detector 14. Then the signals of the original point and the pointer are inputted to a block of two FFs 14a and 14b. An AND value 14c of the outputs of the FFs is obtained. Then the time from the original point and the pointer is obtained as a pulse width. Thus time change of the pressure gage can be readily calibrated.

摘要： PURPOSE:To make it possible to perform automatic measurement, by making the liquid surface of a sample approach to the central axis of rotation, thereby securing measuring accuracy, and linking the processes of sample feeding, measurement, discharge, and washing. CONSTITUTION:A sample 3 is injected to a sample container 2 through a solenoid valve V1 from a sample injecting pipe 11. When the sample 3 reaches a specified amount, the solenoid valve V1 is closed, a solenoid valve V2 is opened, atmospheric pressure is applied, and the sample left in the injecting pipe 11 is pushed into the sample container 2. Then, a solenoid valve V3 of a discharge pipe 12 is opened and sucking is performed. The sample 3 is picked into the sample container 2 at the position of a tip 12a of the discharge pipe accurately. The liquid surface at this time is close to a plane including a central axis 5 of rotation. Then, all the selenoid valves are closed. Cooling water is made to flow through a pipe 18, and the temperature of the sample is decreased. With the sample container 2 being rotated by a motor, the fluidizing point is optically measured. The sample is heated by a heater 34 after measurement, the container 2 is inclined, and the sample is discharged through a pipe 14. Washing of the sample container 2 is performed by injecting the sample 3 from the injecting pipe 11 by a common washing method.
