IPC: H01F27/18
Filed: 1987-12-23
Abstract: PURPOSE:To prevent insulation capability of the title inductor from being reduced by cutting off insulation gas from a refrigerant fluid by bringing a floater into close contact with the internal surface of an insulating vessel when the liquid level of the refrigerant fluid, with which the insulating vessel is filled, is lowered. CONSTITUTION:An iron core 2 and a wiring 3 wound around the iron core 2 are housed in an insulating vessel 4 having an opened top. The vessel 4 is filled with a parfluorocarbon solution 14 to impregnate the iron core 2 and the wiring 3. Then, SF6 gas 15 is introduced into a sealing tank 1. In addition, the perfluorocarbon solution 14 is circulated through a circulation system composed of a liquid/gas separator 10, a cooler 11, and a pump 12. A high tension terminal of the wiring 3 is allowed to penetrate the side of the vessel 4 and introduced into the tank 1 through a lead wire 6, and further connected to a terminal of a stop spacer 5. When the temperature of the perfluorocarbon solution 14 is lowered, the bottom of a floater 7 is brought into close contact with the stopper 8, allowing the surface of the perfluorocarbon 14 to be cut from the SF6 gas 15. Hereby, high insulation strength can be maintained.

Title: Automatic frequency control circuit
Inventor: KISHIGAMI TAKAAKI
IPC: H04L27/14
Filed: 1993-12-22
Abstract: PURPOSE:To reduce the power consumption of the automatic frequency control circuit of an FSK receiver which operates intermittently and makes it nearly follow up the carrier frequency of an FSK signal. CONSTITUTION:A frequency voltage converter 10 converts an I or Q signal into a voltage, which is compared by a voltage comparator 12 with a reference voltage 11. An in-phase/opposite-phase decision means 13 decides the direction of the frequency shift between the carrier frequency and the frequency of a local oscillator 8 from the phase relation between the output signal of the oscillator comparator 12 and a demodulated signal 7, and the decision output is held by a frequency shift direction holding means 15. A frequency variation control signal generating means 14 sets a mode wherein the frequency of the local oscillator 8 is varied before receiving operation is started or after the receiving operation is completed in the intermittent operation. A frequency constant value varying means 16 varies the frequency of the local oscillator 8 by a certain value through the frequency shift holding means 15 to suppress the frequency shift of the local oscillator 8 within a permissible range.

Title: Output data processor for rotary encoder
Inventor: SURIKAWA TOSHIMICHI
IPC: G01D5/249
Filed: 1988-12-23
Abstract: PURPOSE:To prevent an external equipment from stopping abnormally by owing to abnormal code output by correcting the abnormal code into a normal code when it is decided that data outputted from the rotary encoder is the abnormal code. CONSTITUTION:When control operation is started and the rotary encoder inputs Gray code data to an encoder input circuit 4, the data is converted by a CPU 1 into a binary code, which is used to judge whether the rotary encoder rotates forward or backward. When the forward rotation is judged, it is decided whether the data is normal or abnormal from numerals before and after the converted data. Here, if it is decided that the data is abnormal, the abnormal data is converted into its original numeral and it is decided again whether or not the data is abnormal; when no abnormality is decided, arithmetic is performed based upon the data and data inputted from a setting circuit 5 and a control output circuit 7 is controlled so as to control the system. Consequently, the abnormal stop of the system merely due to the abnormal code is evaded.
