Patent JP-H0831663-A (JP)
Title: Transformer winding
Inventor: SAKAMOTO TAKESHI
IPC: H01F27/28
Filed: 1994-07-20
Abstract: PURPOSE:Unify the distribution of flow rate of insulating coolant within a horizontal duct, lower the maximum temperature of a winding, and unify the distribution of temperature rise. CONSTITUTION:A plurality of shunt plates are inserted in the direction of the axis of a disc or helical winding 1 with in a flow bending block. A shunt plate 8 the width of which is smaller than that of the winding 1 is inserted in proximity to the center of the flow bending section in the direction of height in such a way that it projects into the vertical duct 6 on the inlet side. Thus the rate of coolant flowing to a horizontal duct below the shunt plate 8 is increased, and that of coolant flowing to a horizontal duct above the shunt plate 8 is decreased. This unifies the distribution of the flow rate of coolant, and reduces the rise of maximum temperature that will take place without the shunt plate. That also prevents the overcooling of the winding in the upper position, and unifies the distribution of temperature of the winding. In addition, pressure loss within the winding is reduced, and the rate of the circulating flow of coolant is increased.

Since the resonance frequency of each hole is varied by changing the depth of the holes, the filter frequency is simply fine-adjusted.

Title: Controller for externally excited reverse inverter
Inventor: EGAWA KATSUMI
IPC: H02J3/00
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To continuously stably operate an inverter system at a high speed by surely preventing the occurrence of a communication failure even when the fluctuation, waveform distortion, and asymmetry of an AC voltage transiently increase, by providing a tolerance angle controlling the reference value changing means which increases or decreases a tolerance angle control reference value. SOLUTION: An tolerance angle control reference value change circuit 81 inputs a tolerance angle control reference value γ0 and, when the variation of a reverse voltage period γ is transiently large, increase the reference value γ0. A minimum value selection circuit 91 selects a constant tolerance angle control signal from a constant tolerance angle control circuit 73, and inputs the selected control signal to a phase control circuit 92. Therefore, the occurrence of a communication failure can be prevented, because the control circuit 92 performs phase control based on the constant tolerance angle control signal inputted from the selection circuit 91. In addition, an inverter system can be operated continuously stably at a high speed by maintaining the power factor and efficiently of the inverter in a steady state.

IPC: G03B17/24
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a data feedback device capable of accomplishing a stable operation, in the case the voltage of a built-in battery is lowered, in the case the built-in battery is replaced, or even in the case a camera main body is in a standstill state, and also, capable of reducing the consumption of the built-in battery.

Title: Method for desulfurizing molten iron
Inventor: SAWADA TOSHIRO
IPC: C21C1/02
Filed: 1990-06-27
Abstract: PURPOSE:To obtain excellent desulfurizing performance at a low equipment cost in the limited space on casting floor in a blast furnace by blowing desulfurizing agent from a lance in the specific angle range to downward from horizontal plane toward parallel to molten iron stream in a reacting vessel. CONSTITUTION:Into the molten iron 2 in the reacting vessel 16, the lime series desulfurizing agent fed with inert gas from a lance 18 is blown and the molten iron 2 is desulfurized. Herein, blowing of the lance 18 is executed in the range of <=70 deg. angle downward to the angle theta to the horizontal plane toward parallel direction to the molten iron 2 stream. The reason for the above limitation is that, in the case the blowing is upward from the horizontal plane, the desulfurizing agent is floated up on the surface of molten iron 2 at early time and the efficiency is decreased, and on the other hand, in the case the blowing angle theta downward from the horizontal plane exceeds 70 deg., the blown desulfurizing agent is collided to bottom part and becomes turnover flow, and sufficient reaction is not executed and this is floated up on the surface at early time. Then the blowing angle theta from the lance 18 is desirable to be in the range of 10-65 deg. angle downward from the horizontal plane in the point of desulfurizing performance. By blowing, the equal desulfurizing performance as in the case of the torpedo label car can be secured.

IPC: G01H1/00
Filed: 1994-07-21
Abstract: PURPOSE:To minimize the distortion of oscillation waveform even with increase in response to external vibration and enable stably operation by providing a detector, sample hold circuit, comparator, error amplifier and excitation circuit. CONSTITUTION:The amplitudes from vibration detection sensors 11, 12 are controlled to be equal to a set value with sample-and-hold circuits 55, 56 holding the value at a specific phase of a detection signal waveform, a comparator 51 for comparing the held value with an excitation amplitude reference value set in advance, an error amplifier 58 and an excitation circuit 60. Thus, even in the case the vibration amplitude of a pipe begins to be disturbed by the impress of external vibration, the pipe amplitude control is performed with sine wave excitation without waveform distortion as to be a constant value and quick control response can be attained. Furthermore, even with the impress of external oscillation, the frequency characteristics of the system consisting of the detection part and oscillation circuit part does not change, the same characteristics as the frequency characteristics of the detection part can be maintained and so stable flow rate characteristics can always be obtained.
