Filed: 1987-05-09
Abstract: PURPOSE:To reduce the volume of the oil necessary for analyses and to shorten the time for analyses by adding a 3-way selector solenoid valve between an extraction cylinder and solenoid valve. CONSTITUTION:A piping flow passage communicating with the solenoid valve 10 from the extraction cylinder 1 is so changed over by the 3-way selector solenoid valve 22 that the oil flowing from the extraction cylinder 1 is discharged to the outside of the device system without advancing to the solenoid valve 10. The residual sample oil 7 in a chamber 40 is ejected from the extraction cylinder 1 and is discharged to the outside of the device system by the gaseous argon from a cylinder 50 when solenoid valves 15, 24 are opened. A piston rod 3 is operated in succession to move a piston 2 upward and downward several times and to stop the piston at a top dead center so that the flow passage of the solenoid valve 22 is changed over to the initial state. The sample oil 7 remaining in the chamber 40 is completely discharged by the above- mentioned operation. The fresh sample oil 7 is drawn into the extraction cylinder 1 by about 3 times of oil circulation in the process of drawing the sample oil at the time of executing the next analysis.

Filed: 1980-08-13
Abstract: PURPOSE: To ensure positive valve performance by having a valve plate close a valve port and check the backflow with the force of the counterflow perssure, keeping the valve plate closely in contact with the valve port in a pendent position within an circular valve cylinder.  
     CONSTITUTION: A main valve body B-1 and B-2 consists of a valve cylinder 5 and a valve plate 6. This main valve body is divided longitudinally into right and left two chambers by a separator b on which a valve port 9 is provided. The valve plate 6 is freely suspended from the separator (b). In the two chambers, end gates of the valve cylinder 5 are closed by blocking plates 8a and 8b respectively. This makes the liquid flux from one end of the valve cylinder 5 ejected from the other end of the samd cylinder 5 passing through the valve port 9 and pushing the valve plate 6, which however, are closed with the force of the couterflow pressure checking backflow. Since the valve plate 6 is contacted with the valve port 9 in a pendent position, the counterflow pressure is applied to the valve plate 6 and the valve port 9 is  closed immediately. Thus the positive valve performance is ensured.

Title: Magneto-optical recording element
Inventor: ISHII YOSHINOBU
IPC: G11B11/105
Filed: 1990-04-28
Abstract: PURPOSE:To decrease the external magnetic field required for erasing and to decrease the coil current for erasing, etc., by forming an amorphous yttriums- SIALON (Y-SIALON) dielectric layer to 200 - 600 Angstrom  thick. CONSTITUTION:The magneto-optical recording element consists of a transparent substrate 2, dielectric layer 4, magneto-optical recording layer 6, reflecting layer 10, and the dielectric layer comprising Y-Sialon is made 200 - 600 Angstrom thick. In this constitution, intensity of the external magnetic field required for erasing can be decreased without reducing the maximum C/N on recording. If the dielectric film is made >=700 Angstrom  thick, the external magnetic field required for erasing increases. If the film is <200 Angstrom  thick, the maximum C/N decreases, especially decreases in a higher magnetic field. This is because the Y-Sialon dielectric layer is made 200 - 600 Angstrom  thick, and the erasing magnetic field for magneto-optical recording element using the amorphous Y-Sialon dielectric layer can be reduced.
