Title: Dephosphorizing method of molten steel
Inventor: HANMIYOU MASAYUKI
IPC: C21C7/06
Filed: 1983-07-12
Abstract: PURPOSE:To dephosphorize a molten steel at a low cost with a high dephosphorizing rate by adding oxidative molten slag, quicklime, an accelerator for slagging of quicklime to the molten steel which is not deoxidized yet and has a specific concn. of oxigen under force stirring and removing the slag in which the phosphorus in the molten steel is absorbed. CONSTITUTION:A molten steel 3 which is refined in a converter 1, is not deoxidized yet and has >=400ppm concn. of oxygen is put into a vessel 2. About 15-30kg/T oxidative slag used for refining of the molten steel in the refining furnace, about 4-10kg/T quicklime and about 0.1-6kg/T an accelerator for slagging quicklime are added to the molten steel and an inert gas is injected from a lance 5 to stir forcibly the molten steel. Slag for dephosphorization and phosphorus oxide are thus formed, and the phosphorus oxide is absorbed into the slag for dephosphorization. The slag after the dephosphorization of the molten steel existing on the surface of the molten steel 3 subjected to the dephosphorization is sucked by a vacuum slag removing device 6 by which the slag is removed and the rephosphorization in the steel by the slag is prevented.

Title: Controller for diesel engine
Inventor: SHIRAKAWA AKIRA
IPC: F02D41/04
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To always maintain good running and exhaust characteristics by calculating an actual excess air rate from an intake air amount, a fuel injection amount and a exhaust recirculation amount, comparing this with a target excess air rate set according to an engine state and controlling the opening degree of an exhaust recirculation control valve according to its deviation. SOLUTION: The pressure of an intake system is predicted by a predicting means 111 based on the respective measured values of an engine revolution number, an amount of intake air and an intake temperature. The pressure of an exhaust system is also predicted by a predicting means 113 based on the detected results of the amount of intake air, the intake temperature and an engine load. Then, an EGR amount is predicted by an EGR amount predicting means 112 based on the respective predicted values of an EGR valve opening degree and the pressures of the intake system and the exhaust system, and an actual excess air rate is calculated from the EGR amount, the amount of intake air and a fuel injection amount.  This is compared with a target excess air rate calculated by a calculating means 116 based on the engine revolution number and the engine load by a comparing means 115 and, according to its deviation, the opening degree of the EGR valve is adjusted by an EGR valve control means 117.

Title: Vehicular brake device
Inventor: SUZUKI YOSHIHIKO
IPC: B60T13/40
Filed: 1994-05-17
Abstract: PURPOSE:To secure an air control action, when a fluid type retarder device fails and pressure air leaks from one air tank by avoiding lowering of pressure in an other air tank through a process of closing a switch valve and supplying pressure air from a compressor. CONSTITUTION:When a retarder switch 5 is switched, for example, to (2) position, pressure air from a second air from a second air tank 4 is inducted into the pressure chamber 17c of a pneumatic cylinder device 17 through a first switching valve 31 so that a clutch device 13 may be put in connection. Therefore a supporting member 19 is turned and a rotor 16 integrally formed thereto also turns together with a rotary shaft 10. At that time, a second switching valve 32 stays in a low pressure position (d) and pressure air in the second air tank 4 is supplied to the air chamber 25d of an air-liquid converting device 25 through a first pressure reducing valve 33, resulting in generation of braking torque in a fluid type retarder 11. The switching valve 9 is switched to a closed position (d) by a control unit 100 when the pressure air in the second air tank 4 leaks.

Abstract: PURPOSE:To eliminate the irritation of the user for waiting time and to prevent reception of erroneous character signal by informing the reception of a normal character signal through a display device to the user and displaying program information recorded in a spare display memory during the waiting time until the information of the selected program is transmitted. CONSTITUTION:When the user observes an LED display and selects a program of character broadcast, the selected program information is fed to a cahracter signal processing section 2.

Abstract: PURPOSE: To make the pretilt angle of liquid crystal molecules close to 0° and obviate the occurrence of reverse tilt at the voltage application by evaporating an orientation treatment material onto the substrate surfaces from specific two directions simultaneously or repeatedly alternately.  
     CONSTITUTION: Substrates 43 of liquid crystal cells with their orientation treatment sides being faced outside are mounted to a rotator 42 which rotates about a rotating axis 14. A mask plate 44 which defines the angle of vapor deposition is provided between a vapor source 47 which produces vapor currents 48 and the rotator 42. This plate 44 is formed with a first vapor deposition hole 45 being in the direction inclined 80° from the normal of the substrate 43 and a second vapor deposition hole 46 being in the normal direction. Out of the vapor currents 48, only those which have passed through the holes 45, 46 deposit on the substrates 43 at the vapor deposition angle within a fixed range. As the rotator 42 rotates, the first and second vapor depositions take place alternately. Thereby, the repetitive stability of orientation characteristics in volume production is improved

Abstract: PURPOSE:To make it possible to obtain a highly stable current detector having a wide dynamic range, by simple circuit constitution such that the magnetical deviation of a magnetic core due to a measuring current is detected on the basis of the change in the operation of a separately-excited oscillation circuit. CONSTITUTION:A base current is supplied to transistors 10a, 10b in an alternating manner through an exciting transformer 40 by the rectangular wave output from an exciting oscillator 41 and the transistors 10a, 10b are brough to an ON- state in an alternating manner. In such a state that a current to be measured is not flowed to winding 1-1, the current flowing to resistors 20a, 20b are respectively same in amplitude and a time width. However, when a DC current or a low frequency alternating current is flowed to the winding 1-1 of the current to be measured, the operative point of a magnetic core 1 is shifted and difference is generated between the magnitudes of currents flowed to the resistors 20a, 20b. Therefore, difference is generated between the outputs of smoothing circuits 21a, 21b and signal output voltage with polarity proportional to the magnitude of the current to be measured and corresponding to the flow direction thereof is obtained at the output terminal of a differential circuit 22.
