Filed: 1981-10-23
Abstract: PURPOSE:To obtain a hexagonal platy or plate alpha-iron oxiee useful as a raw material for hig-grade ferrite or magnetic recording, by the hydrothermal treatment of gamma-Fe2O3 in an aqueous alkaline solution. CONSTITUTION:An iron compound consisting of gamma-Fe2O3 as a principal component is subjected to the hydrothermal treatment in an aqueous alkaline solution. Expensive gamma-Fe2O3 for magnetic recording prepared by passing through the steps of dehydrating, reducing and slowly oxidizing goethite or inexpensive gamma-Fe2O3 prepared by further oxidizing magnetite obtained from iron ore, etc. may be  used as the gamma-Fe2O3.

Abstract: PROBLEM TO BE SOLVED: To provide a process for simultaneously producing polycrystalline silicon and zinc chloride which are stable in quality as solar batteries and are dealable with a cost reduction. SOLUTION: This process for producing the polycrystalline silicon and the zinc chloride consists in reducing silicon tetrachloride in a liquid or gaseous state by molten zinc, taking a mixture contg. the formed polycrystalline silicon and zinc chloride out of a reaction vessel 5 and housing this mixture into a separating vessel 10, separating the zinc chloride and polycrystalline silicon in the mixture, then recovering both from the separating vessel. The reduction of the silicon tetrachloride is preferably executed by introducing the silicon tetrachloride in the liquid or gaseous state into the reaction vessel where the molten zinc exists. In this process for production of the polycrystalline silicon, the by-produced zinc chloride is separated from the mixture 7 and thereafter the metal zinc and chlorine are recovered by effecting electrolysis.  The recovered metal zinc is used again as a reducing agent for the silicon tetrachloride and/or the recovered chlorine is used for the chlorination treatment of the metal silicon provided as a prestage.

Abstract: PURPOSE:To execute powder-compressed-compacting into a green compact having boss and flange under good production yield by beforehand avoiding breakage of the flange at the time of extrusion so as to release pushing pressure to lower part of an upper outer punch. CONSTITUTION:Constitution of a pressing machine 1 forms flowing passage 15 communicating from outer circumference of an upper ram 2a for an upper die 2 to a compressed chamber R3 separately with a venting passage L4 as different as the conventional machine. At the last compressed position (lower dead center), air having the prescribed pressure is blown from a flowing passage L1 and flowing passage L3 into a compressed chamber RO and lower chamber, to vent the air in an upper chamber R1 and lower chamber. Then, the upper outer punch 2c is ascended under pressing an upper inner punch 2b downward. By this method, movement of the green compact is restrained at the time of extrusion and also the flange is not pressed downward by contacting the lower end of the punch 2c with the flange of the green compact as the conventional machine. Therefore, the breakage of the flange can be prevented.

Abstract: PURPOSE:To have no fixed phase angle between the make and the break of a relay contact and therefore increasing the lifetime of this relay contact, by turning on and off a relay coil synchronously with the pulse obtained by differentiating another frequency which is not synchronous with the frequency of a commercial power supply. CONSTITUTION:A commercial power supply 8 of a temperature controller is divided in terms of voltage by a temperature setting resistance 1 and a temperature sensor 2 for production of a temperature signal 20. This signal 20 is compared with the reference voltage 21 by a temperature comparator 3. The output of the comparator 3 is applied to a non-reverse input terminal 25 of a pulse comparator 23. While a self-running oscillator 30 is connected to a reverse input terminal 26 of the comparator 3. The output of a fixed cycle which is larger than the frequency of the power supply 8 and given from the oscillator 30 is applied to the terminal 26. At the same time, the DC voltage 31 is divided by resistances R1 and R2 and applied to the terminal 26. Then a switching element 4 is controlled by the pulse obtained by differentiating the signal of a fixed cycle sent from the oscillator 30. Then a relay coil 5 is turned on and off by the element 4 and a fixed phase angle is not set between the make and the break of a relay contact 6. This increases the lifetime of the contact 6.

Filed: 1995-07-05
Abstract: PROBLEM TO BE SOLVED: To relieve the working burden of a user and to facilitate the input of plotting data by inhibiting the plotting for the part exceeding the boundary of existing plotting data when newly inputted plotting data exceeds the boundary. SOLUTION: When the plotting data 31 by a line drawing is already plotted, the new input of a locus 32 is performed by an input means. But, when other existing plotting data 31 exists, the acquired coordinate of an inputted plotting coordinate is stored in a RAM, a vector performing a plotting by the two coordinates of the coordinate and the coordinate of continuous plotting data just before is determined, and after the vector is stored in the RAM, the range in which the plotting is actually performed is determined by the plotting vector. Because this plotting vector is overlapped with other existing plotting data 31 and the plotting for the part exceeding the other existing plotting data 31 is inhibited when a plotting flag is not ON, the plotting flag is set on. Therefore, the plotting for the part exceeding other existing plotting data 31 is not performed.
