Filed: 1981-06-02
Abstract: PURPOSE:To make the internal temp. distributions of produced slabs, etc. uniform, to eliminate the need for reheating and to improve productivity by providing a heat insulating part between the final rollers of a continuous casting installation and a cutter. CONSTITUTION:In a continuous casting installation, a heat insulating part 11 is provided between final rolls 7a, and a cutter 10, and cooling capacity is decreased by decreasing the number of sprays near the rolls 7a. Therefore, unsolidified parts remain partly in a slab when it passes through the rolls 7a. When  such slab or the like enters the part 11, there is virtually no cooling from the  outside and therefore the surface of the slab or the like is gradually heated by  the heat conduction from the inside. The unsolidified parts at the center are  gradually cooled by the heat conduction to the surface, and solidify by around  the time when it goes out from the part 11. At the point of a cutter 10, no unsolidified parts exist. If necessary, an induction heater is provided to the part 11.

Title: Preparation of alkali metal dichromate and chromic acid by means of electrolysis
Inventor: HERUMUUTO KUROTSUTSU
IPC: C25B1/28
Filed: 1990-04-02
Abstract: PURPOSE: To make it possible to prevent the drop of a cell voltage and the degradation in membrane functions by the intra-membrane precipitation of a polyvalent cation compd. by specifying a cation exchange membrane and forming an aq. soln. of a specific pH in a cathode chamber at the time of producing alkali dichromate metal salts and chromic acids in a cell where electrolytic chambers are separated by this membrane.  
     CONSTITUTION: The alkali dichromate metal salts and chromic acids are produced by electrolyzing the alkali mono- or dichromate alkali metal salt soln. in the electrolyte cell where the anode chamber and the cathode chamber are separated by the cation exchange membrane. In this method, the electrolysis is effected by using a cation exchange membrane type single layer structure membrane consisting of a perfluorinated polymer having a sulfonic acid group as a cation exchange group as a base body to form the aq. soln. of pH of 4 to 14 in the cathode chamber of the cell. The current efficiency which is equal to the efficiency obtainable when using the two-layered structure membrane and is not attainable heretofore is obtd. This cell voltage is sufficiently lower than in the case of the two-layered structure membrane. Further, the precipitation of the polyvalent cation compd. in the membrane may be averted.

Title: Intermittent load mechanism, printer using the same, and control method therefor
Inventor: HIRABAYASHI KENICHI
IPC: B41J19/00
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To reduce a maximum load, miniaturize a motor and eventually form a printer compact and light-weight, by averaging a load to be connected to a carriage motor. SOLUTION: The printer has a carriage motor, a drive pulley 2 driven by the carriage motor, a belt suspended between the drive pulley 2 and a driven pulley 3 for moving a carriage 5, a mechanism intermittently connecting an external load in accordance with a movement direction of the carriage 5, and a control mechanism. When the carriage 5 moves to be close to the drive pulley 2, the control mechanism brings the load mechanism into a connection state. When the carriage 5 moves to be close to the driven pulley 3, the control mechanism brings the load mechanism into a disconnection state. Accordingly, when a relatively large axial load is given rise to the driven pulley 3, the axial load and external load are adapted not to act to the carriage motor simultaneously.

Title: Driver circuit for motor fan
Inventor: MATSUDA SHUICHI
IPC: H02P29/00
Filed: 1990-03-30
Abstract: PURPOSE:To prevent the generation of surge currents by linearly fluctuating the reference voltage used for an error amplifier circuit in response to an ambient temperature. CONSTITUTION:The output voltage Vout of a variable resistance means 10 is used as power for driving a motor fan. A proportional-signal generating means 50 fluctuates the reference voltage in direct proportion to a temperature Ta on the basis of the temperature Ta detected by the detecting means 40 of the ambient temperature in the vicinity of an object to be cooled. Regarding a signal clamping circuit 60, the voltage determined by the minimum voltage required for driving the motor fan is used as the reference voltage when the output voltage of the proportional-signal generating means 50 is lower than the first reference voltage Vth1, and the voltage determined by the maximum voltage permitted for driving the motor fan is employed as the reference voltage when the output voltage is higher than the second reference voltage Vth2. An error amplifier circuit 30 compares the output voltage Vout of the variable resistance means 10 and reference voltage, and transmits a control signal over the variable resistance means 10 in the direction that the error is reduced.

Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To fill powder with uniform cleanliness and without executing a degassing treatment by incorporating a prescribed quantity of pre-alloyed powder into a sealable vessel. SOLUTION: A storing vessel 10 for pre-alloyed powder is arranged as a supplying source for the powder through a piping system 12 to a compressive mold 14. The vessel 10, mold 14 and piping system 12 are evacuated with a vacuum pump 16. In such a case, the evacuation of the vessel 10 and the mold 14 is executed in turn or in the same time. The powder quantity carried through the piping system 12 is regulated by working a valve 38 and an amplitude supplying device 40. At the time of filling the powder into the mold 14 to a prescribed level, a level indicating device 42 is removed and its stem part 44 is heated and bent and the mold is mechanically closed. In such a way, the powder is continuously exposed to the vacuum. Therefore, the powder in the mold 14 is uniformized from the upper part to the bottom part.
