Title: Control system of synchronous motor
Inventor: NASHIKI MASAYUKI
IPC: H02P6/08
Filed: 1984-02-22
Abstract: PURPOSE:To remedy to an ultrafine torque command by forming the product of a current amplitude, a magnetic flux density of a rotor and a cosine value of the phase difference of a current flowed to a stator winding proportional to the torque command so that the torque generated in a synchronous motor coincides with the torque command. CONSTITUTION:A current amplitude IA is calculated by a calculator 20 on the basis of a torque command T and the prescribed value TL, and the magnetic flux density of a rotor and the cosine cosalpha of the phase difference alpha of the current flowed to a stator winding are calculated by a calculator 21. A 3-phase sinusoidal wave generator 2A generates sinusoidal wave signals s1-s3 in which the phases are displaced at 120 deg. for deciding the phase of the current flowed to the stator winding and the frequency corresponding to the rotating position of the rotor. The current of the stator winding is controlled so that the product of the torque T, the current amplitude IA and the cosine value cosalpha are proportional.

Title: Two-screen display device
Inventor: HOSODA KIYOSHI
IPC: H04N5/45
Filed: 1990-02-13
Abstract: PURPOSE:To improve the picture quality by controlling the lightness of a slave screen depending on the relation between the lightness of a master screen and the lightness of the slave screen. CONSTITUTION:When a master screen is dark, a voltage is increased because a beam current of a picture tube is decreased and a base voltage EQ4 of a transistor(TR) Q4 is higher and an output voltage VOUT is increased. When a light screen is inserted as a slave screen under the condition, a base voltage EQ3 of a TRQ3 gets lower and shifted in the direction of EQ4>EQ3 and an output voltage VOUT is increased. Thus, the impedance of TRs Q6, Q7 is lowered and a control voltage fed to a processing circuit 11 by variable resistors VRa, VRb is decreased to decrease a DC level of the video signal for the slave screen and the amplitude level. Thus, the extremely bright screen of the slave screen inserted in the master screen is prevented when the master screen is dark.

And then, if the surface of the polymer coating film 2 which is treated with the corona discharge is treated with a cloth at one direction, as the one side of the fine rugged surface is cut larger than the opposite side thereof, the shape of rugged surface has directional property. The grade of directional property in the rugged shape is specified mainly by the pressure of rubbing. Thus, the liquid crystal molecule 3 is stably arranged at the one direction with the tilt angle theta, as the rugged shape has the directional property.

Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To improve the detecting performance of a radar equipment without complicating the structure of a high frequency circuit. SOLUTION: In this radar device 10, a voltage control oscillator 12 capable of controlling a oscillation frequency with a modulation signal Sm and adjusting the change rate of the oscillation frequency to the modulation signal Sm with a control signal Sk generates a transmission signal Ss whose frequency is modulated into a triangular wave to be linearly increased/decreased with time, the transmission signal Ss being changed in a frequency modulation width only without changing a modulation cycle as the control signal Sk is changed. In response thereto, a frequency band representing a beat signal Sb composed of transmission/receiving signals Ss (L), Sr mixed is changed. As a result, the beat signal can be always detected in the frequency band, less affected by outside noise and low frequency noise, by properly changing the control signal Sk.

Title: Melting method for bearing steel
Inventor: SHINJO YUTAKA
IPC: B22D1/00
Filed: 1987-02-18
Abstract: PURPOSE:To reduce the production cost by adding CaO-Al2O3 series slag having the specific SiO2 activity into molten steel and executing degassing treatment after severely stirring by blowing inert gas. CONSTITUTION:At the time of shifting the molten bearing steel, which completes the blowing in a converter, into a ladle, the CaO-Al2O3 series slag having <=0.0004 SiO2 activity, is added into the molten steel at the prescribed ratio. Next, inert gas of Ar gas, etc., is injected into the molten steel in the ladle to execute severe stirring. Then, the molten surface is sealed by the inert gas and the slag on the molten steel surface is perfectly melted. Most part of Al2O3 generated by deoxidizing and hard quality inclusions of MgO, TiO2, etc., are absorbed and separated into flux during severe stirring. After that, the degassing is executed by vacuum degassing, etc., to remove deoxidized products. As the hard quality inclusion is removed and the refining time is drastically shortened, the production cost is reduced.
