Title: Method and device for controlling induction motor
Inventor: ISHIDA SEIJI
IPC: H02P27/06
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To suppress an overcurrent and a stall by controlling a voltage so that the current flowing through an induction motor becomes a current limit value or less when the current flowing through the induction motor exceeds the specified current limit value and decreasing an output frequency at the same time. SOLUTION: The AC voltage of a power supply 1 is converted into a DC voltage by a converter 2. The DC voltage is smoothed by a capacitor 3. The smoothed DC voltage is converted into the variable-voltage and variable-current AC by an inverter 4. Then, an induction motor 5 is driven by the inverter 4. The currents Iu and Iw of the induction motor 5 are detected by a current detector 6. When the currents Iu and Iw exceeds the specified current limit value, the voltage is controlled so that the current flowing through the induction motor 5 becomes the current limit value or less by a PWM control part 9, and the output frequency is decreased at the same time. Thus, the overcurrent and the stall can be suppressed even when the load of the induction motor 5 is large.

Title: Utilizing method for excess air of blower of blast furnace
Inventor: OKEWATARI TAKEAKI
IPC: C21B7/00
Filed: 1978-03-25
Abstract: PURPOSE: To reduce electric power and apparatuses required for obtaining process air, by utilizing excess air discharged from a blower of a blast furnace as process air in the plant, the excess air which is unnecessary for the furnace operation, without releasing it in the air.  
     CONSTITUTION: Pressure of compressed air to be used in a blast furnace and discharged from a blower 3 is measured by a discharge-pressure gage 5, and the suction air flow of the blower by an air-flow meter 2. From the discharge pressure and suction air flow, it is possible, in reference to the surge line, to estimate whether the blast furnace is maintained at satisfactory air-flow condition or not, hence air flow is increased more than necessary for the blast furnace to an air-flow region where no surge is caused. Air necessary for the blast furnace is delivered through a hot stove 9 to the blast furnace 19. Excess air is cooled by a cooler 10, pressuirized by a compressor 13 and is stored in an accumulator 20, so as to meet with the increase of required process air. Surplus air beyond that is released through an air- discharge valve 17, a silencer 18.

Abstract: PURPOSE:To prolong the durable life of a magnetic circuit part and a rotation supporting mechanism part by separating and disposing the rotation supporting mechanism part and the magnetic circuit part in axial longitudinal direction and providing a heat generating source and transmitting member in separate positions. CONSTITUTION:An iron core 3 wound with bearings 1a, 2b which are the rotation supporting mechanism members and a coil which is the magnetic circuit member and a magnet 9 disposed to face this iron core are separately disposed in the axial longitudinal direction. The bearings 1a, 2b generate the friction heat thereof by rotation and this heat is released by a rotating body 6 as a radiator. Heat is generated in the coil 4 by passing the current necessary for generating a rotating force. This heat is transferred and radiated through the iron core 3 to a stator frame 11. Namely, the heat which the rotation supporting mechanism part generates by rotation and the heat which the magnetic circuit part possesses are radiated respectively through the different members. The durable life of the rotation supporting mechanism part and the magnetic circuit part is prolonged in this way.

Title: Method for driving electrophotographic printer
Inventor: KOBAYASHI TETSUYA
IPC: G03G15/04
Filed: 1988-02-18
Abstract: PURPOSE:To uniformize printing density at both times of solid black printing and every other dot printing, in performing printing, by a method wherein the printing time of ON printing data is made different corresponding to the ON/OFF combination of printing data adjacent to each other from the aspect of the rotary direction of a rotary photosensitive body and printing data adjacent to each other from the aspect of the direction right-angled to the rotary direction. CONSTITUTION:When there is OFF printing data next to ON printing data, the printing time t2 of the ON printing data is made relatively long and, when there is the ON printing data next to the ON printing data, the printing time t1 of the ON printing data is made relatively short. Since the magnitude of exposure energy is proportional to a printing time, when the printing time t2 of the ON printing data is relatively long, the magnitude of exposure energy E2' becomes same to that of exposure energy E1' when a printing ON-part is continued even if the next is the OFF printing data and density can be made uniform at both times of solid black printing and every other dot printing.

Abstract: PROBLEM TO BE SOLVED: To improve the sealing property of a float valve and a valve seat face by forming a valve seat of the float valve which is operated by air which passes an air introduction valve which is opened due to the deformation of a diaphragm in such a manner that it has a radius of curvature in a pump device having an air supply device which supplies air into a water storage tank. SOLUTION: When the operation of a pump main body is started to pump up water and pressure of an air layer 1500 in a tank 200 reaches a predetermined value, a pressure switch 1300 is operated to stop the operation of a pump device. Moreover, when pressure on a suction side of the pump main body becomes negative pressure, pressure in a second chamber 305 of an air supply device 300 becomes negative pressure, and a diaphragm 303 is inverted. Consequently, pressure in a first chamber 304 also becomes negative pressure, and stored water rises in a pipe 600 to press a float valve 700 against a valve seat 301b so that the entry of stored water into the first chamber 304 is prevented.  At this time, the valve seat face 301b is formed in such a manner that it has radius of curvature 1.1 to 1.2 times radius of curvature of the float valve 700 to increase the sealing property of the float valve 700 and the valve seat face 301b.
