Title: Oil leakage detector for oil-filled apparatus
Inventor: KOBAYASHI MASAHIKO
IPC: F16N29/00
Filed: 1989-02-21
Abstract: PURPOSE:To aim at the promotion of unmanned operation and automation for an oil-filled apparatus by operating a time change in a difference between an oil level calculated out of oil temperature and an actual oil level through an oil gauge, and when any oil leakage has occurred in the oil-filled apparatus, calculating such a time as reaching to a level where the oil level comes impossible to continue the operation of a transformer. CONSTITUTION:An oil level arithmetic unit 5 calculates difference x1,  x2 between an oil level being calculated out of oil temperature by a temperature detector 4, corresponding to each of detection times t1 and t2 (t1<t2) and an actual oil level by an oil gauge 3 installed in a conservator 2. In addition, a difference  x between a transformer operation uncontinuable level of an oil level at the time t2 and the oil level being calculated out of oil temperature. As for these time and oil level differences, such time t3 that the difference  x2 increases as it is and comes to the difference  x is calculated at a continuous duration calculating device 6. Accordingly, at an interval from the final calculating time t2 to the transformer operation uncontinuable time t3 if load distribution for a sound transformer is performed, a stable supply of power is thus promoted.

Title: Pulse count circuit
Inventor: YATSUDA YUTAKA
IPC: H03K21/00
Filed: 1988-02-24
Abstract: PURPOSE:To eliminate need for monitoring a level of a reset signal at all times and to execute other arithmetic processing while 1st and 2nd interruption signals are not inputted by using a reset signal whose level is inverted by an inverter as the 1st interruption signal and using the reset signal as it is as the 2nd interruption signal and giving them to a central processing unit. CONSTITUTION:The reset signal is transferred to the 2nd interruption signal input terminal INT 2 of a CPU 4' via an input circuit 2-2 and an input port 3-2. The CPU 4' sets a flag representing read enable to a counter 5 to, e.g., '0' to inhibit the read of the CPU 4' of the count to the counter 5 and restores to the normal arithmetic processing procedure. When the reset signal reaches a level 'L', since the level of the inverted reset signal goes to 'H', the CPU 4' starts counting the counter 5 by using the inverted reset signal inputted to the 1st interruption signal input terminal INT 1, sets the enable flag to '1' thereby enabling the read of the count of the counter 5 and restors to the normal arithmetic processing. Thus, it is not required to confirms the level state of the reset signal for each prescribed interval and while the 1st and 2nd interruption signals are not inputted, other arithmetic processing is executed.

Title: Output buffer circuit
Inventor: KONDO HITOSHI
IPC: H03K19/0175
Filed: 1993-03-01
Abstract: PURPOSE:To eliminate malfunction due to fluctuation of a power supply voltage attended with ringing noises and a through-current at an output state transition by driving the gate of a MOS transistor (TR) at a constant current and selecting a gate voltage in the OFF state to be a specific value. CONSTITUTION:A source of an N-channel MOS TRN is connected to a GND (ground voltage), its drain is connected to an output line Z to form a sink/open drain output buffer circuit. A constant current source Iref supplies a predetermined current to a gate of the TRN1 via a switch TRPO to drive the gate. Thus, a ringing noise in the output state transition is reduced thereby. A constant voltage source Bias applies a gate voltage to the TRN1 when it is turned off via a switch TR NO to set the gate voltage to be a constant offset voltage lower than a threshold voltage of the TR 1.

IPC: G01B7/28
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To provide high-reliability estimated information about the finished shape of an improved body. SOLUTION: An electrode fitting body 14 is installed for estimating a diameter DX. The fitting body 14 is provided with current electrodes PI and potential electrodes PV. An arithmetic means 20 determines the measured resistance value Rreal per unit length of an improved body 12 from the potential difference V when a current I flows between the current electrodes PI. The relation between the resistance value R and diameter D per unit length of a simulated improved body is obtained based on the specific resistances ρ1 of improved bodies of multiple kinds and the specific resistance ρ2 of the natural ground by the two-dimensional axisymmetric finite element method with the ratio between the specific resistances ρ1, ρ2 used as a factor.  When the measured specific resistance ρ1 real of the improved body 12 and the measured specific resistance ρ2 real of the natural ground 10 are obtained, the factor which is the ratio between the specific resistances ρ1, ρ2 is selected from the ratio between them, thereby the relation between the resistance value R and diameter D of the simulated improved body is specified, and the diameter DX can be estimated by collating the measured resistance value Rreal with this relation.

Title: Method and apparatus for optimization of transmission power of communication apparatus
Inventor: FURANKU CHIYAARUZU GUUIN OOEN
IPC: H04B7/26
Filed: 1991-03-06
Abstract: PURPOSE: To reduce the occurrence of undesirable interference by making a divided duplex frequency channel communication system transmit certain basic system information, timing information, etc., as a standard idling beacon message at every frame from a primary station and a paging message at every 16 frames to a secondary station during an idling period, but not transmit the standard idling beacon message during such a long idling period as the nighttime, etc., because the message can become a source of interference. CONSTITUTION: Primary stations PS-PS4 invite in-range secondary stations SS1-SS6 which participate in transmission in a low-duty cycle link mode in which paging messages and low-duty cycle link reconfirming messages are sent at relatively long intervals for transmission in accordance with a certain condition decided by the primary stations PS1-PS4. In the low-duty cycle link mode, the secondary stations are controlled to act at desired intervals. When the ambient environment increases, however, a system is inverted into a standard idling state.
