Title: Magnetic recording medium and production thereof
Inventor: FUDA EIJI
IPC: B42D15/10
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To change the safety by dispersing magnetic powder roughly and densely at least in one part of a magnetic recording layer, in a magnetic recording medium having at least one layer on the medium, to prevent forgery. SOLUTION: An electromagnet 3 having a yoke is installed in the vicinity of the opposite side to a magnetic material coating surface 2 on the transportation path of a base body 1 in an undried state and a coil driving power source 4 is connected to the electromagnet 3 and, moreover, a noise generator 5 is connected to the power source 4. The output of the power source 4 is controlled by the waveform of the output of the generator 5 and the magnetic field generated by the electromagnet 3 is changed also in accordance with it. Since magnetic material is not dried and still has flowability, the magnetic field from the neiboring electromagnet 3 becomes strong in this state, the magnetic material is attracted along the magnetic field.  That is, since the magnetic material bemomes dense when the magnetic field is strong and rough when the field is weak, in comformity with the changing of the magnetic field, a fringe pattern is formed on the coating surface 2. Since this fringe pattern immadiately enters a drying furnace the fringe pattern is dried and fixed as it is.

Abstract: PURPOSE: To control the blast moisture of plural blast furnaces with inexpensive installations  without addition of steam by providing one unit of titled installation to plural blower suction  sides, and providing selector valves for atmospheric air and dehumidified air opening-adjustably to the respective blowers.  
     CONSTITUTION: Atmospheric air is dehumidified with a dehumidification blasting installation 2,  and is fed through the selector valves 12A, 12 of respective branch pipes 4 to the suction side  filters 5 of the blowers 6 of blast furnaces 8A, 8. Atmospheric air selector valves 13 are provided on the upper stream side of the filters 5. For example, if the furnace 8A does not require dehumidified air on account of blowing down or the like, the load of the installation 2  can be reduced by fully opening the valve 12A. Differences are produced in some cases in the  blast moisture contents between the respective furnaces 8 in the state of operation changes.  Therefore, the blast moisture contents toward the blast furnaces are detected with blower outlet moisture content detectors 9. When the blast moisture contents are set with setters 14 and  when the values thereof are larger than the values of a detector 10 for moisture contents after  dehumidification, open commands are emitted to the valves 13, and the valves begin to open,  through which the atmospheric air is included into the blower suction sides. Thereafter, the differences between the values of the detectors 9 and the set value are fed back and the openings  of the valves 13 are controlled, whereby the moisture contents are made equal to the set  values.

Filed: 1985-08-16
Abstract: PURPOSE:To offer a compatibility of sufficient kneadability and high molding stability by providing a mixing part at least on one of either supply side or extrusion side of resin and controlling the accumulation of shearing force. CONSTITUTION:Usually the straight screw having compression ratio 1 is used as the supply part 11 and the compression ratio of compression part 12 is increased up to under 3 by making the groove of screw shallower gradually.

Title: Safety device for pilot flame

IPC: F23N5/10
Filed: 1980-12-23
Abstract: PURPOSE:To reduce a power consumption at a power supply by a method wherein an energization of coil for retracting an armature of a solenoid valve is performed by a constant current circuit while a predetermined period of time and the energization of the coil is made by an electromotive force of a thermocouple after the predetermined period of time is passed. CONSTITUTION:When a switch 22 is turned on, a charging is performed for a capacitor 25 up to a voltage Vs. The voltage Vs is applied to an input terminal (+) of an amplifier 31. At this time, the thermocouple 8 shows insufficient heating and less electromotive force, so that an output is made at 31 to cause the transistor 26 to be operated. Then, the emitter current IE is flowed to the coil 27 and the thermocoupler 8. IE becomes a constant current when a relation of VAC=VS is found and an electric current is continued to flow in the coil 27, so that an armature of the solenoid valve is kept at its retracted condition.  Thermocoupler 8 is heated by a pilot flame and IE and an electric current from the thermocoupler 8 are flowed in the coil 27, IE is reduced while a time is lapsed, and then a supply of electric current from the power supply 23 may be turned off. After that, it is kept by an electric current from the thermocoupler 8.
