Title: Speed-control device of induction motor
Inventor: ISHII SHINICHI
IPC: H02P21/22
Filed: 1999-09-07
Abstract: PROBLEM TO BE SOLVED: To maintain a rotor speed at a specific value by reflecting the fluctuation of a stator coil winding resistance value and a rotator conductor resistance value to that of a primary current (d) axis constitutent for compensating for the amount of sliding. SOLUTION: A multiplier 10 multiplies the amount of a slip ωs1 (1) of a first state being maintained by an amount-of-slip computing element 8 by  i1d(1)/i1d(2)}2 being outputted from a first amount-of-correction computing element 9 for obtaining the amount of slip ωs1 (2) of a second state. The amount of a slip ωs1 (2) of a second state is inputted into an adder 11. Then, the adder 11 adds a secondary angular frequency command value ω2* to the amount of slip ωs1 (2) of a second state for calculating a primary angular frequency command value ω1*, and the ω1* is inputted to a voltage vector computing element 7 and an integrator 6.  More specifically, according to the change in a primary current d-axis constituent for reflecting the fluctuation of each resistance value, the amount of slip is changed, thus maintaining the rotational speed of an induction motor at a prescribed value, even when the resistance value is fluctuated by temperature increase.

Filed: 1989-09-29
Abstract: PURPOSE:To automate inspection by utilizing the light of an IR region as a light beam for the purpose of detection and approximating the irradiation diameter of the light beam to the size of the color picture elements of color filters. CONSTITUTION:A defect (projection) 22 by foreign matter 20 is detected by utilizing scattered light and the light of an IR region, more particularly, the light of >=700nm wavelength are used as the light beam for this purpose. The scattered light of the edges is averaged and the steep parts from the edges do not exist any longer as the spot diameter of the light beam is more approximated to the size of the respective color picture elements 14R, 14G, 14B and, therefore, the weakening of the intensity of the scattered light from the defect part by the foreign matter 20 is obviated and the intensities of the scattered light from the end parts of the color picture elements 14R, 14G, 14B are nearly equalized to each other regardless of the differences in colors. The signals corresponding to the parts of the projections 22 are thus detected.

Abstract: PURPOSE:To obtain a high-reliability, rigid sensor by fixing 1st and 4th rotary magnetic poles on the input and output shafts of a torsion bar, fixing 2nd and 3rd rotary magnetic poles to an inside rotary cylinder, and engaging the 1st and 2nd, and 3rd and 4th magnetic poles with each other. CONSTITUTION:An annular coil 14 is surrounded with hollow annular stator iron cores 10 and 11 and doughnut disk type rotary magnetic poles 6 and 7 placed inside the iron cores 10 and 11 to form the magnetic path of the coil 14. Teeth cut in the mutually opposite flanks of the magnetic poles 6 and 7 engage with each other. Similarly, the magnetic path of a coil 17 is formed to an annular coil 17, iron cores 12 and 13, and rotary magnetic poles 8 and 9, which engage with each other. Then when positive-directional torque is applied to a torsion bar 21, a gap is formed between the teeth of the magnetic poles 6 and 7 and the teeth of the magnetic poles 8 and 9 engage with each other closely, so the self-inductance of the coil 14 decreases. When negative- directional torque is applied, on the other hand, the self-inductance of the coil 17 decreases. For the purpose, variation in the self-inductance of the coils 14 and 17 is detected to detect the torque.

IPC: B01J20/06
Filed: 1988-10-07
Abstract: PURPOSE:To enable high-efficient adsorption of a sulfur series and a nitrogen series odor material by a method wherein a deodorant is formed with mixture powder of 30-60wt.% a bamboo leaf-shaped water-containing ferric oxide particle powder having a major axis of 0.2-1.0mum and an axial ratio of 3-10 and 40-70wt.% solid acid powder. CONSTITUTION:A title deodorant is formed by mixture powder of 30-60wt.% water-containing ferric oxide particle powder formed in the shape of a bamboo leaf having streaklike superfine structure and a major axis of 0.2-1.0mum and an axial ratio of 3-10 and 40-70wt.% solid acid powder. The water-containing ferric oxide particle powder effectively adsorbs a sulfur series odor material and adsorbs accompanied moisture content in priority. Thereby, solid acid is not influenced by a moisture content and a nitrogen series odor material is effectively adsorbed by acid nature which solid acid powder has. This constitution enables high-efficient adsorption of both a sulfur series and a nitrogen series odor material without being influence by a moisture content and without the occurrence of a handling risk and especially even during the use of an ordinary temperature dry type.
