摘要： PURPOSE:To automatically display the degree of deterioration and to facilitate the easy conduction of maintenance and inspection operations by integrating and magnetically shielding sensors, a processing circuit, a display device, and a power source device. CONSTITUTION:The moisture detecting sensor 12 and the temp. detecting sensor 13 are housed in a magnetically shieldable supporting pipe 15. The sensors 12, 13 are communicated with the gaseous nitrogen atmosphere of a metering transformer via the many holes of this pipe 15. The processing device 14 determines the moisture content and temp. in an insulating oil from the output signals from the sensors 12, 13, compares the moisture content and a specified value to decide the degree of the deterioration of the insulating oil. The data on the permissible moisture content with respect to oil temp. is previously stored in a memory 16. The device 14 outputs the results of the decision to the display device 17. The device 17 emits light from 3 pieces of LED elements varying in colors to make display toward the operator on the ground according to whether the degree of the deterioration is normal, cautionary or abnormal. The switching circuit 18 makes the circuit conducting and nonconducting by the IR remote control signal projected from the operator.

摘要： PURPOSE:To produce the patrol items en bloc by registering plural basic patterns of a patrol subject and also preparing a data base where the patrol contents are previously produced and edited. CONSTITUTION:A substation defining function Mf2 extracts a component pattern of a specific subject out of plural component patterns showing the constitution of each patrol subject and then changes the kinds and the types of these equipments. A patrol item editing function Mf3 edits individually the patrol items produced by the function Mf2. Then, a patrol data base function Mf4 reads a patrol result file F2 stored in an IC memory card IC of a handy terminal 1 after the patrol is complete and registers the patrol result in an external storage as a patrol data base F3. Furthermore, the function Mf4 retrieves the desired patrol result out of the base F3, as necessary, with a patrol item used as a key word, sorts the patrol results for rearrangement, and turns the data into a graph.

摘要： PURPOSE:To equalize the space of a liquid crystal cell and to improve the yield by pressing both surfaces of the liquid crystal cell by a flexible film as the external film of a liquid alveolus which contains pressurized liquid, and charging liquid crystal and sealing the liquid injection hole of the liquid crystal cell. CONSTITUTION:The liquid crystal cell 2 is fitted in a bag which contains liquid in an external container, i.e., the liquid alveolus 10 whose outside is made of the flexible film 9, the pressure in the liquid crystal cell 2 is reduced in a vacuum evacuating device, and then the liquid crystal injection hole of the liquid crystal cell 2 is dipped in the liquid crystal bath in a boat 7 containing the liquid crystal 1. Then, while the boat 7 of the liquid crystal bath and liquid crystal cell 2 are held, the container 8 is put back to atmospheric pressure entirely to inject the liquid crystal 1 into the liquid crystal cell 2. Then, while the liquid crystal 1 is injected into the liquid crystal cell 2 and the liquid crystal injection hole is sealed, the outsides of the substrates 3 and 4 of the liquid crystal cell 2 are pressed by the liquid alveolus 10. Consequently, the space between the substrates 3 and 4 is made constant and the yield is improved.
