Title: Method for operating oxygen bottom blown converter
Inventor: TAMURA NOZOMI
IPC: C21C5/34
Filed: 1990-02-19
Abstract: PURPOSE:To melt the base metal sticking to the wall of an oxygen bottom blown converter and to fluidize slag so as to make improvement in the yield and charging quantity by top blowing a regulated quantity of oxygen to mainly burn the gaseous CO generated in the converter in the period when a molten iron is subjected to decarburization refining in the above-mentioned converter. CONSTITUTION:The molten iron 5 of a main iron source is subjected to the decarburization refining by bottom blowing oxygen in the bottom blown converter 1 having bottom blowing tuyeres 8. Only the bottom blown refining is executed in the region exceeding 80% of the total bottom blowing oxygen quantity in the method for operating the above-mentioned oxygen bottom blown converter 1. The gaseous oxygen for burning the gaseous CO generated in the converter is supplied from a top blowing lance 4 in the arbitrary period within the refining period of 0 to 80% of the total bottom blowing oxygen quantity. This top blowing oxygen quantity is confined to <=30% of the above-mentioned total bottom blowing oxygen quantity at this time and the ratio of the oxygen to be used for the decarburization in this top blowing oxygen is confined to <=30%, more preferably 0%. The deposition of heat on the converter wall is attained by this combustion heat, by which the base metal sticking to the converter wall is melted and the slag 6 is fluidized. The improvement in the yield, charging quantity, the yield of steel tapping, etc., is made in this way.

IPC: G02B7/08
Filed: 1988-02-18
Abstract: PURPOSE:To eliminate oscillation, mechanical sounds, and image skip for lens movement and to miniaturize a device by providing a lens barrel and an enclosure with an engaging part and an engaging groove which are brought into contact with each other to freely slidably support the barrel. CONSTITUTION:Projection parts 13 on the outside peripheral surface of a lens barrel 11 in which a lens 10 is built are engaged with engaging grooves 14 on the inside surface of an enclosure 12, and the barrel 11 is slidable in the direction of the optical axis. A screw 19 is elastically engaged with a tooth part 17 of the barrel 11 by an elastic holder. When a pulse motor 31 is rotated in this constitution, the barrel 11 is slided in the direction of the optical axis without being rotated. Since contacting among gears is eliminated, the occurrence of oscillation, mechanical sounds, and image skip is prevented. The barrel 11 is supported at three points in the enclosure 12, and a high torque is not required, and the motor 31 and the device are miniaturized.

Title: Power supply device, discharge lamp-lighting system, and lighting system
Inventor: SHIRATA NOBUYA
IPC: H02M7/538
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To reduce generation of unbalance and connection failures by inputting the DC voltage of a DC power supply device for alternately turning on and off for switching, and by setting voltage applied between the gate and the source of a P-type FET to be larger than that for an N-type FET for alternately turning on and off a switching device. SOLUTION: Switching devices 7 and 8 connected in series with each other are provided between the output terminals of a DC voltage device 1. The source of an N-type FET 7 is connected to that of a P-type FET 8, and their gates are also mutually connected. A drive means 9 applies a voltage between the gate and the source of the FETs 7 and 8, and alternately turns on and off the FETs 7 and 8. The output of the drive means 9 sets the voltage applied between the gate and the source of the P-type FET 8 to be larger than that being applied between the gate and the source of the N-type FET 7 and decreases the on-resistance of the P-type FET 8 corresponding to the increase in the voltage which is applied between the gate and the source, thus allowing the calorific values of the FETs to approach, and hence providing heat radiation countermeasures and balancing the service life.

IPC: C07K16/00
Filed: 1990-02-17
Abstract: NEW MATERIAL:A hybridoma cell obtained by cell fusion of a splenic cell from an animal immunized with erythropoietin to a myelomatous cell. USE:For producing erythropoietin used in treating patients suffering from anemia, after operation or under artificial dialysis. PREPARATION:For example, urine of a patient suffering from anemia is ultrafiltered to remove low molecular substances. The resultant ultrafiltrate is then concentrated, desalted and lyophilized for providing the whole urinary protein powder, which is subsequently dissolved in a buffer solution, subjected to multistage chromatography and purified to afford erythropoietin. The resultant erythropoietin is then administered to immunize a BALB/C mouse. After the final immunization, a splenic cell is subsequently collected, subjected to cell fusion to a myelomatous cell and cultured in a hypoxanthine-aminopterin- thymidine(HAT) culture medium to provide a hybridoma cell. A clone having the ability to produce an antibody reactive with the erythropoietin is subsequently selected and cloned by a limiting dilution method, etc., to afford the hybridoma cell having the ability to produce the objective monoclonal antibody.

Title: Mold molding method
Inventor: SATAKE TOSHIYUKI
IPC: B22C9/02
Filed: 1979-03-30
Abstract: PURPOSE: To achieve the prevention of cracking of the casting by adding shrinkable material into molding sand or using the same in combination with mold core grid or using the same to the both of these simultaneously.  
     CONSTITUTION: When shrinkable material is added to molding sand, the expansion of sand particles 1 is offset by the shrinkage of the layer of a binder 2 and the shrinkable material 4 between the sand particles 1 and further when the shrinkage of metal 3 begins, the binder 2 and material 4 carbonize to have reduced volume, thus acting in the direction of not hampering the shrinkage of the metal 3 and therefore the crack-free casting is obtained. In addition, when said material is used in combination with a core grid, the expansion of the core grid 12 is absorbed by the shrinkable material 16 in the process that the casting 11 solidifies and at the same time, the shrinking of the casting 11 is also absorbed by the material 16 and therefore the sound crack-free casting 11 may be obtained. If the addition to the molding sand and the combination use with the core grid are employed simultaneously, the much higher effect may be obtained.

Abstract: PURPOSE:To make it possible to heighten the measuring sensitivity while preventing errors attributed to pyroelectric effect in an acceleration sensor using a piezoelectric body. CONSTITUTION:A piezo-electric ceramic plate 13 is sandwiched between plate- shaped elastic bodies 11 and 12. Each one of the elastic bodies 11 and 12 is fixed on a rigid body 14 and the other end thereof is made free. The piezoelectric ceramic plate 13 has a polarization shaft parallel along the length of the elastic bodies 11 and 12 and an electrode is formed parallel with the polarization shaft. Then, a load 15 is arranged on the free end side of the elastic body 11.

Title: Reference voltage generating circuit
Inventor: HIRAGA KATSUHIKO
IPC: G01R31/28
Filed: 1989-02-16
Abstract: PURPOSE:To enable detection of an optimal triming bit at a high speed by a hardware with respect to a set voltage applied from outside by detecting an optimal feedback control information to make an output voltage equal to the set voltage. CONSTITUTION:When a set voltage EIN is applied from outside, first an output voltage EA of a voltage amplification means 12 is compared with a set voltage EIN and a comparison information CD is inputted into a feedback control means 14. Then, a feedback control information FD is outputted to a feedback means 15 of the means 12 from the means 14. At this point, a relationship of a voltage EO of a voltage generation source 11 and the output voltage EA of the means 12 turns to EO X times as much as that. The voltage EA is compared with the voltage EIN by a voltage sequential comparison means 13. Moreover, this feedback control processing is repeated sequentially and when the voltage EA coincides with the voltage EIN, the feedback control information FD is regarded as optimal feedback control information. Thus, by fixing the output voltage EA thus obtained, the voltage can be a reference voltage ER for a reference voltage generation circuit thereby enabling a processing of setting a reference voltage at a high speed by a hardware.
