Title: Dc-component detection apparatus
Inventor: YUGOU MASAKI
IPC: G01R19/00
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To obtain a DC-component detection apparatus by which an inverter is not stopped erroneously when a DC component is generated by a transient cause without the failure of the inverter in order to realize a high operation rate and which can be manufactured at low costs. SOLUTION: In a DC-component detection apparatus, a drop voltage due to a DC component in the output current of an inverter 12 connected to a system is integrated by an integrator 11 whose cutoff frequency is high and by an integrator 12 whose cutoff frequency is lower. When the difference between their integrated values is larger than a definite reference voltage Vref2 , the DC component is regarded as being generated by a transient cause, and the operation of the inverter 12 is not stopped. On the other hand, when the difference between the integrated values is smaller than the reference voltage Vref2 , the inverter 12 is stopped when the integrated value of the integrator 21 is larger than a reference voltage Vref1 which is sufficient to be regarded as a failure.

Inventor: ASANO YOSHIKI
IPC: A01K80/00
Filed: 1986-12-15
Abstract: PURPOSE:To obtain a metal ring for forming a girder net being hardly sinkable in sand by forming a circular section metal ring into a flat-shaped section metal ring in which a flat face is formed on both the top and bottom faces by press working in the top to bottom direction. CONSTITUTION:A metal coil with a prescribed diameter is formed by use of a circular section metal bar and a part of the coil is cut and both cur free ends of a C-shaped ring are butt welded. After annealing a weld zone 2, the ring is pressed in the top to bottom direction to form a flat-shaped section metal ring 1 having a flat face 1' formed on both the top and bottom faces of the ring 1 and the ring 1 is quenched and tempered. A trawl net stretching a girder net in which the metal rings 1 are connected and fixed to each other is easy to be trawled because the girder net are hardly sinkable in sand and have a small resistance against dragging.

Title: Method for controlling induction motor
Inventor: OKUYAMA TOSHIAKI
IPC: H02P21/14
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To compensate an effect by the fluctuation of motor constant in a speed controlling device for an induction motor. SOLUTION: A current detector 4 detects a d-axis and q-axis constituents of the primary current of an induction motor 2. Following the fluctuation from the base value of the detected d-axis constituent, a motor constant is identified. Based on this identified value, the output voltage of an inverter 1 is corrected. It is possible to identify each fluctuation amount of the primary resistor and reactance. This makes it possible to compensate the fluctuation amounts of the d-axis and q-axis voltages highly precisely. As a result, it is possible to control the speed of the induction motor 2 without facing inconvenience including the fluctuation of the induced electromotive force of the induction motor 2.

Abstract: PURPOSE: To make the size of a flow meter as small as possible by arranging a vane on the downstream side from the jet nozzle of a fluid and detect buoyancy acting on the vane. CONSTITUTION: A vane 4 is set on the downstream side from a jet nozzle 3 formed in a flow meter main body 1.

As the result, the support bodies are displaced, and a strain gauge 6 detects its displacement to be outputted according to distortion quantity. A flow quantity operator 8 computes the flow quantity based on the output from the strain gauge 6 to display the same on a display 9.
