Title: Image scanner for facsimile equipment
Inventor: YOSHIDA AKIHIRO
IPC: H04N1/10
Filed: 1991-03-15
Abstract: PURPOSE:To read only a desired page directly effectively by scanning a page desired to be read and fed downward by a roller with a read section and elevating a support with an elevating/descending device so as to discharge the original upward. CONSTITUTION:When a start button for read is depressed, a stepping motor 9 drives a pinion 10, supports 4a, 4b are descended and a page 5 desired to be read is led into a casing 1 from a paper supply port 11. The page 5 is inserted between platen rollers 13 and fed downward. In this case, a CPU 14 controls a motor 9 so that the feeding speed of the page 5 downward and the descending speed of the supports 4a, 4b are equal to each other. Simultaneously the page 5 fed downward is scanned by a read section 15. The scanning is continued till the supports 4a, 4b are fully descended to the lower limit from the upper limit. Then the CPU 14 judges the end of read at the lower limit to reverse the motor 9 and to lift up the original 3 thereby discharging it from the paper supply port 11.

Title: Replacing device for fuel assembly
Inventor: ODA YORIO
IPC: G21C19/19
Filed: 1990-03-02
Abstract: PURPOSE:To simplify and easily put a fuel assembly in and out of the upper space of a reactor core through a riser tube by making the lateral folding size of a work part which guides a fuel rod gripper smaller than the internal diameter of the hole part of the riser tube. CONSTITUTION:The in-reactor manipulator 40 is assembled by using a swivel part 42, an elevation part 43, the work part 44, etc., and suspended in the riser tube 15, and the lower end part of the elevation part 43 and the work part 44 are inserted up to the upper space of the reactor core through the hole 45 of the riser tube 15. At this time, a main link 61a is directed right below by synchronous operation between an actuator 61c for angle setting and an actuator 61b for parallel setting and a hand part 62 is moved down, thereby making the folding size S of the work part smaller than the internal diameter D of the narrow part of the riser tube 15. Consequently, the work part 44 can easily be put in and out by simple upward/downward moving operation. The work part 44 which is inserted into the reactor core upper space is released from being folded, the fuel assembly 14 is extracted and loaded, and passed to and received from the fuel gripper 11, thereby making the replacing operation smooth.

Title: Temperature protector circuit for two-shaft gas turbine
Inventor: MIYATA TERUO
IPC: F02C9/00
Filed: 1979-04-27
Abstract: PURPOSE: To prevent overheating of gas turbine and to keep a high accelerating performance of the same independently of the change in the temperature of intake air, by detecting the temperature at the inlet of compressor, comparing the same with a reference temperature, and determining the allowance for the temperature at the inlet of gas generator from the above comparison of temperatures.  
     CONSTITUTION: Temperature T 1  at the inlet of compressor 1, detected by temperature detector 51, is directed to comparator 53 and compared with output T 1 D of reference temperature setter 52. From the comparator 53, deviation signal (T 1 - T 1 D) is afforded to gain setter 57, which in turn produces a correction signal ΔTM for the allowance of the temperature at the inlet of gas generator on the basis of deviation (T 1 -T 1 D) of the intake temperature and furnishes it to comparator 59. Comparator 59 calculates the deviation between output ΔTD of reference signal setter 58 and output ΔTM of setter 57 and affords allowance for the temperature at the inlet of gas generator (ΔT=ΔTD-ΔTM) to adder 29.

IPC: G01C3/04
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To shorten a storage time and to shorten an entire range-finding time by making a rate to change the storage time by deciding reflected light from a measuring object at the time of automatic gain control larger than a rate to shorten the storage time by deciding only the quantity of external light at the time of external light saturation control. SOLUTION: When the quantity of external light component is larger than a 1st specified value (S204), the opening time of an electronic shutter is set to 1/2 in order to shorten the storage time requried for storage once by considering that output from a skim CCD sensor is saturated by the external light component (S205). When the quantity of reflected light component from the measuring object is larger than a 2nd specified value (S207), the opening time of the electronic shutter is set to 1/4 in order to shorten the storage time required for storage once by considering that the output from the skim CCD sensor is saturated by the reflected light component from the measuring object (S208). Such operation is repeated unitl the output from the skim CCD sensor is not saturated, and the storage time of the sensor is set to an appropriate value.

Inventor: FUJITA YUKO
IPC: B01D53/14
Filed: 1985-03-14
Abstract: PURPOSE:To increase the disoxidation effect at the low temp. by press- contacting a mixture of bis(salicylaldehyde)ethylenediiminecobalt (II) or its derivative and polytetrafluoroethylene on a net or a lath made of metal. CONSTITUTION:A disoxidation material is molded by press-contacting a mixture of bis(salicylaldehyde)ethylenediiminecobalt (II) or its derivative and polyte trafluoroethylene on a net or a lath made of metal. The disoxidation material is regenerated by immersing it into water at 60-100 deg.C and thereby separating the oxygen absorbed on bis(salicylaldehyde)ethylenediiminecobalt (II) or its derivative. By this generating method, since the temp. does not exceed >=100 deg.C, the decrease of the repeating adsorption and desorption capacities of oxygen of salcomine can be suppressed.

Filed: 1984-03-19
Abstract: PURPOSE:To control precisely the rate of blowing a slurry from tuyeres with low driving force and an inexpensive installation by controlling and circulating the slurry by a closed loop constituted of a hermetic tank, feed pipe, annular header and return pipe. CONSTITUTION:The slurry in a storage tank 1 is fed by a booster pump 9 which permits control of the number of revolution to a hermetic tank 8 via a press feed pipe 10. The slurry is then fed by a feed pump 2 to an annular header 3 via a feed pipe 5 and is blown from discharge nozzles 4' of branches 4 for blowing tuyeres into a blast furnace. The balance is returned via a return pipe 6 to the tank 8. The difference in flow rate between the pipe 5 and the pipe 6 is made equal to the rate of blowing through the tuyeres and is made equal to the rate of supply from the pump 9 to the tank 8. The number of revolution of the pump 9 is controlled to control the discharge rate and flow rate by which the blowing rate from the tuyeres is controlled and therefore the initial cost is reduced and the loss of the driving power cost is eliminated.

Abstract: PURPOSE:To prevent the occurrence of chamber by deviating the width center of  the rolling material to the side of larger mill stiffness than the rolling mill center to  eliminate the apparent mill stiffness, and performing rolling in the rolling mill  having a mill stiffness difference between both sides. CONSTITUTION:With the rolling mill 9 having a mill stiffness difference between the drive side and work side, motors 14W, 14D are driven to open and close the both sides equally to the right and left with respect to the rolling mill center MC to adjust the opening corresponding to the width of the rolling material. Thence,  the motors 14D, 14d are driven to set the side guides 10 with a deviation of the  specified spacing from the rolling mill center MC to the drive side DS side of higher  mill stiffness. Because of this, the material may be bitten in the rolls with a deviation by the specified spacing and the apparent mill stiffness difference is erased. It  is desirable to use the work roll 22 having the roll curve according to the foregoing  deviated spacing for the roll.
