Filed: 1988-05-27
Abstract: PURPOSE:To reduce the amt. of powder to be entrained by a vapor current and discharged and to improve the recovery of powder by providing a vapor outlet so that the ascending passage of the vapor generated on the inner periphery of the barrel is blocked. CONSTITUTION:A raw liq. is supplied into the barrel 1 from a raw liq. supply port 2, dispersed on the inner periphery of the barrel 1 by a rotating raw liq. distribution ring 3, and sent downward in the form of film. The solvent component is vaporized by the heating steam supplied into a heating jacket 7 through the barrel 1, and the liq. is dried, powdered, and discharged from a powder outlet 11 at the lower part. Meanwhile, the solvent vapor 13 and powder 14 entrained by the vapor in the barrel 1 ascend on the inner periphery of the barrel, and reach a vapor outlet 10. Since the outlet 10 is provided within the inner diameter of the barrel, the ascending passage is blocked, and the entrained powder 14 is allowed to collide with the outer face of the outlet 10, turned away from the ascending passage, and dropped by gravity.

Abstract: PURPOSE:To improve the preservation characteristic of a nonaqueous electrolyte battery by using a positive electrode containing as its active material, manganese dioxide the surface of which is converted into a lower oxide through thermal treatment carried out by infrared rays. CONSTITUTION:Manganese dioxide is first treated in a conventional furnace to 350-430 deg.C and is then secondarily treated in an infrared furnace to 550-650 deg.C. Here, a very short time (approx. 30-60sec) is required to achieve the high temperature state. Next, the thus treated manganese dioxide active material is mixed with, for example, 10pts.wt. of acetylene black used as a conductive agent and 6pts.wt. of fluorine resin powder used as a binding agent to prepare a positive mixture. The thus prepared positive mixture is then pressed and molded before being thermally treated at 300 deg.C to make a positive electrode 1. A negative electrode 2 is made by punching a rolled lithium plate. Electrolyte is prepared, for example, by dissolving 1 molar concentration of lithium perchlorate in a mixture solvent consisting of equal volumes of propylene carbonate and 1,2- dimethoxyethane.

Abstract: PURPOSE:To attain the temperature compensation of a diode by providing a voltage dividing type compressiong circuit comprising a resistor and a series circuit consisting of diodes of anti-parallel connection and a resistor to a signal compression circuit to make the input sensitivity curve variable easily. CONSTITUTION:When a sinusoidal wave Vi is inputted to a terminal A, a non-inverting input Vs of an amplifier 7 becomes Vs=kT/q.ln(ID/Is)+R4ID, where ID is a diode current and Is is a reverse current of diode. The 1st term of equation expressing Vs is dominant when ID(Vi) is small and the 2nd term is dominant when the ID(Vi) is large. The sensitivity curve of the compressing circuit changing from this logarithmic compression into linear range is changed by changing the value of resistors 1, 4. Further, the current is increased by DELTAID when the forward voltage of the diode is decreased because of temperature change, the Vs is about to increase by DELTAIDR4 by changing the resistor R4, resulting in that the circuit acts like compensating the change in the Vs due to temperature.

Title: Anti-clouding treatment of inorganic and organic plate glass and mirror
Inventor: SHIKAMATA KATSUO
IPC: C08J7/04
Filed: 1982-07-27
Abstract: PURPOSE:To prevent glass or a mirror from being clouded by a temp. change over a long term, by directly coating the glass or mirror with a resin having hydroxyl groups and by baking and solidifying the resin to form a transparent film. CONSTITUTION:The surface of plate glass or a morror is degreased with a detergent or the like, coated with a soln., and air-dried until the coated surface is smoothened. The soln. is prepared by diluting polyvinyl alcohol to 1-10% concn., dissolving it perfectly, mixing 1-3C lower alcohol by 10-30% so as to accelerate evaporation, and blending a small amount of a curing agent after dissolving the alcohol perfectly. The coated surface is then dried with hot air at 100-160 deg.C, and the resulting film is solidified by cross-linking under heating to form a transparent thin film producing an anti-clouding effect on the surface of the glass or mirror without causing distortion. Since the film has hydroxyl groups, it has a great affinity for water and produces a remarkable anti-clouding effect. THe resin surface is cured by baking, so the effect can be sustained over a long term.
