Title: Starting up method of waste treating arc furnace
Inventor: FURUKAWA TOSHIHARU
IPC: F23G5/00
Filed: 1979-12-05
Abstract: PURPOSE: To save conductive material while facilitating the starting up of operation by generating arc with the actuation of a conductive material feeder checking to see if there is no arc generated in a given time after arc charging is made ready.  
     CONSTITUTION: An electrode 4 is lowered from the top of a slag 21 and made ready for arc charging connected to the power source. As no arc is produced when the slag 21 is not melted at a high temperature, a signal S from a furnace controller 19 activates a timer for a control panel 17. When the detection current of a current transformer 18 is below the specified level in a given time afterward, a motor 15 is rotated for a fixed time to feed a conductive material 11 in a hopper 13 onto the slag 21 whereby an arc is produced between the conductive material 11 and the electrode 4. This eliminates wasteful consumption of the conductive material 11 and facilitates the starting of operation of the furnace.

Title: Pyroelectric infrared ray sensor
Inventor: FUJIKAWA KAZUHIKO
IPC: G01J1/02
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To obtain an infrared rays sensor with high sensitivity and low cost by a method wherein a gas of which a main component is flown is sealed in a sealing body. SOLUTION: A pyroelectric 5 has a spontaneous polarization and always generates a surface electric charge, but in a constant state in an outer air, neutrality is electrically held by coupling with electric changes in the outer air. If infrared rays are incident thereon, a temperature of the pyroelectric is charged, and according thereto, in an electric charge state of the surface, a neutral state is also broken and changed. At this point, electric charges generated on the surface are detected and an incident amount of the infrared rays can be measured. A high resistor 6 stabilizes a sensor output by stabilizing discharging of electric charges of the pyroelectric 5. A FET 7 matches impedance with an external circuit. A lead pin 8 is inserted into a fixing pedestal 4 so as to be electrically joined to the pyroelectric 5, the high resistor 7 and the FET 7.  A gas of which a main component is flon 10 of low cost is sealed in a space 9, and thermal conductivity from the pyroelectric 5 is suppressed, whereby high sensitivity of a sensor output is realized.

Title: Recovering method of heavy metal by iron sulfide
Inventor: NAKAYAMA DAIKI
IPC: C22B7/00
Filed: 1982-09-10
Abstract: PURPOSE:To remove and recover efficiently heavy metals from waste water, by adding an iron component to a liquid contg. heavy metals according to need, and thickening the sulfide obtd. by adding sulfide ions thereto by using a magnetic field. CONSTITUTION:If a liquid is approximately neutral and contains an excess iron- component with respect to the content of heavy metals, said liquid is used as it is. If the liquid is strongly acidic or alkaline, the liquid is neutralized to about 5-8pH and if the iron component is not enough, a water soluble iron component of about 10 times of the total molar concn. of the predicted heavy metals is added to the liquid. H2S is passed through such liquid or an ammonium sulfide soln. is added thereto under stirring to form the black precipitate of iron sulfide. The formation of the other heavy metal sulfides has been completed when the formation of said precipitate is completed. Since the magnetism is weak right after the reaction, the liquid is allowed to rest for about 5 days or to heat and cool. Thereafter, when the strong magnetic field is applied to the liquid, iron sulfide flocculates along the magnetic field and therefore this part is separated and the heavy metal parts contg. iron are removed and recovered.
