Filed: 1993-05-07
Abstract: PURPOSE:To provide a liquid level measuring equipment by which the liquid level can be measured accurately with no influence of the electric conductivity of liquid, the installation environment, etc. CONSTITUTION:First and second electrode rods 10, 11 are immersed into a liquid 13 and the potential difference between them, when a voltage is applied from a power supply 15, is fed through a measuring section 16 to a liquid level calculating section 17 where the liquid level is determined. A third electrode rod 21 having a lower end position L1 is also provided and when the liquid level drops below L1, output from a comparator 24 is inverted and delivered to an electric conduction coefficient calculating section 20. The calculating section 20 receives the potential difference between the electrode rods 10, 11 at that time and adds an error component (difference from an actually measured value) caused by the ambient conditions to the electric conductivity of the liquid thus determining an electric conduction coefficient which is then fed to the liquid level calculating section. Since the electric conduction coefficient is determined based on a known level L1 and a potential difference obtained through actual measurement of an objective liquid, the liquid level determined through subsequent calculations has no difference from actually measured value.

IPC: G11B11/105
Filed: 1988-05-27
Abstract: PURPOSE:To perform erasure and recording with one time of operation as keeping the direction of an external magnetic field constant by constituting a device in sequence of a substrate, a first magnetic layer, a second magnetic layer, and a superconducting layer observing from a light projecting plane. CONSTITUTION:The device is constituted in sequence of the substrate 11, the first magnetic layer 12, the second magnetic layer 13, and the superconducting layer 14 observing from the light projecting plane. The coercive force of the first magnetic layer 12 at a room temperature is larger than that of the second magnetic layer 13 at the room temperature, and also, the superconducting layer 14 is a superconductor at the room temperature, and cuts a magnetic field from the outside unless heat is applied. In other words, when a convergence beam 26 is set at a high level, the temperature of an irradiated part up to the superconducting layer 14 rises, and it goes to a regular conductor, and passes the external magnetic field 24, and decides the magnetization of the first magnetic layer 12 that is a recording film by the external magnetic field 24. Also, when the convergence beam 26 is set at a low level, only the temperature of the first magnetic layer 12 rises, and the direction of the magnetization of the first magnetic layer 12 is decided by the magnetic field 25 of the second magnetic layer 13. In such a way, it is possible to perform the recording and the erasure simultaneously in a state keeping the direction of external magnetic field constant.

Abstract: PURPOSE:To prevent breakage of mechanical parts other than a detecting means for an appropriate stopping position of a plate, which malfunctions, by providing a control means for stopping the movement of the plate when no signal is obtained from the detecting means. CONSTITUTION:When an elevating signal is issued to start the operation of a timer means T, if no stopping signal is issued from a photo interrupter 23 within a time (t) set on the timer means T, it is determined that the photo interrupter 23 is abnormal, and therefore, a motor 6 is stopped at once by a stopping signal delivered when the time (t) elapses. Further, since a stopper 25 is provided abutting against an intermediate plate 2, at a position slightly above a suitable stopping position, the intermediate plate 2 is subjected to a load by the stopper 25. Upon receiving of the load by the stopper 25, a torque transmission force by the fastening force of a coil spring 11 is overcome so that the coil spring 11 races around the boss of a sprocket 9b, and therefore, the travel force of a chain 12 exceeding a predetermined value is isolated. Further, after a time T elapses, an elevation signal for the motor is cut off.

Abstract: PURPOSE:To enable the same optical system to take measurements by sing P polarized light and S polarized light by using polarizers for extracting >=2 kinds of polarized light beams and a rotary disk to which a window for leading out reference signals synchronized with the respective polarizers is fitted. CONSTITUTION:A potentiostat 21 sets the potential of a sample electrode 8 to a specific potential and a function generator 22 superposes and AC voltage. Then, a light source 9 is turned on and homogeneous light is obtained through a monochromatic meter 10 and passed through the polarizers 1 and 2 while the rotary disk 5 with the polarizers is rotated to extract the P polarized light and S polarized light as pulse light beams, which are projected on the surface of an electrode 8. The polarized light beams are reflected by the surface of the electrode 8 and detected as the pulse light beams by a photo-multiplier 14, and they are converted into electric signals, which are inputted to relays 131 and 132. The rotary disk 5, on the other hand, rotates and the moment the homogeneous light passes through the polarizer 1, light emitted by a generator 1 passes through a window 4, but the light is reflected by the rotary disk 5 at other times to return to the generator 11. Namely, reflection is caused by the rotary disk 5 at the timing of the generation of the P or S polarized light to generate a breakpoint, generating a pulse.
