IPC: G01K1/02
Filed: 1982-08-04
Abstract: PURPOSE:To detect precisely a temperature difference at each part in a tank and to prevent a tank rollover by leading out and measuring temperature differences between plural sensors fitted in the tank in the height direction and reference sensors fitted to a float. CONSTITUTION:The sensors 4A-4N are fitted at equal intervals from the bottom surface to the ceiling in the tank.

Title: Auxiliary navigation apparatus
Inventor: NARUSHIGE YOSHIHIRO
IPC: G01S5/12
Filed: 1986-06-10
Abstract: PURPOSE:To determine the position of an own ship hyperbolic navigation system becomes impossible, by operating the intersecting points of the circumference of the circle around a ship emitting an auxiliary navigation radio wave and the hyperbola operated from the hyperbolic navigation radio waves from two transmission stations. CONSTITUTION:Since a ship 72 is present in the areas 92a, 93a within the receiving boundaries 92, 93 of loran radio waves from a master station 82 and a sub-station 83, one hyperbola 62 can be calculated from the loran radio waves from two stations 82, 83. However, since the ship 72 is present out of the boundary 91 with respect to the loran radio wave from the sub-station 81, a hyperbola calculated by the pair with the master station 82 can not be operated and the position of an own ship can not decided and, therefore, an auxiliary navigation wave is transmitted from a ship 71. An auxiliary navigation receiving part 14 operates the distance up to the ship 71 from a time receiving the time reference mark of the auxiliary navigation radio wave 32 and transmitted time information. Next, the circumference of a circle 62 having the operated distance as a radius is operated to be outputted to a hybrid part 12. The hybrid part 12 operates the intersecting points of the hyperbola and the circumference of the circle 61 and the position of the own ship before a short time is referred to from two intersecting points to set one of two intersecting points as the position of the own ship to output the same to a display part 13.

Title: Excitation device for electromagnet apparatus
Inventor: KAMIYA HIROSHI
IPC: H01F7/18
Filed: 1987-05-30
Abstract: PURPOSE:To save power consumption by simultaneously exciting a start coil and a holding coil, moving a movable body, generating an induced electromotive force on the holding coil and deexciting the start coil through detection of such induced electromotive force. CONSTITUTION:When a switch 24 is turned conductive, the main control circuit 25 applies a voltage to the lines 29, 30 through the lines 26, 27. Thereby, the start coil 2 is excited and an output voltage of power supply 23 is lowered by DELTAv1 from the voltage at the time of deexcitation due to the internal resistance of power supply 23. The main control circuit 25 applies a voltage to the holding coil 3 and the pulses p1, p2 are superposed to the lines 31, 32. A level discrimination circuit 33 discriminates the level of pulse p2 with the discrimination level Vl and applies an inactivation signal having the predetermined pulse width to the main control circuit 25 and auxiliary control circuit 28 from the line 34. Thereby, the auxiliary control circuit 28 cuts off the excitation power of the lines 29, 30. Only the holding coil 3 is excited and the start coil 2 is kept deexcited and therefore power consumption of electromagnet apparatus 1 can be saved.

Title: Abnormal state detecting device of resistance welding machine
Inventor: WAKABAYASHI MAKOTO
IPC: B23K11/24
Filed: 1981-08-31
Abstract: PURPOSE:To detect an abnormal state of a welding machine, and to prevent welding failure, by correcting an operation value of an ignition phase angle of an AC switching means, in accordance with a variation of an input electric power supply of the primary side of a transformer, comparing this output value with a stored value, and detecting its dissidence. CONSTITUTION:When a welding machine is operating normally, a reference ignition phase angle data PD coincides with an ignition phase angle data PD', therefore, a signal (a) is not outputted from a comparator 19. For instance, if even one of secondary cables 5A, 5B, 6A and 6B is separated from a welding transformer or is disconnected due to installation failure, a peak value of AC voltage V0 of the primary side becomes high instantaneously, and its voltage value rises. Therefore, a phase angle commanding device 12 outputs an ignition phase angle data PD1 for resetting the voltage V0 to its original value. Therefore, an ignition phase angle data PD'1 which is an output of a correcting device 16 is also varied together with PD1, and accordingly, the signal (a) is outputted from the comparator 19, and an abnormal state such as disconnection of a secondary cable, etc. is detected.
