IPC: G11B33/14
Filed: 1987-06-17
Abstract: PURPOSE:To stably start even in a low environmental temperature by providing various means for detecting heat, temperature and comparing with a prescribed threshold closely to an integrated circuit in which a write in and write out circuit is incorporated. CONSTITUTION:The resistance value of a thermister 20 is changed according to the temperature and an inclination thereof indicates a negative. A transforming circuit 21 passes a weak current to the thermister 20 to obtain a voltage corresponding to the resistance value of the thermister 20 and output as the output voltage 31 of the transforming circuit. A comparing circuit 22 the voltage VR of a direct current power source 23 with the output voltage 31, outputs a difference voltage DELTAV and a current source 24 passes an output current to a resistor 1. The voltage VR of the direct current source 23 is set in such a manner that a value TR transformed to the temperature of the thermister completely exceeds a lower limit temperature for assuring the operation of the writing and reading integrated circuit 5 and does not exceed an average temperature at the time of a successive operation. The maximum current of the current source 24 is set to a value which does not deteriorate the reliability of the writing and reading integrated circuit 5 according to the rise in the temperature due to the heating of the resistor 1 at the time of a successive discharge. Accordingly, at the time of starting in the low temperature environment, a stable writing and reading operation can be assured.

Filed: 1995-05-26
Abstract: PURPOSE: To obtain a capacity detection circuit in which the ratio of capacity can be detected stably regardless of the ambient temperature by eliminating the effect of offset voltage of amplifier or the charges of a switching transistor. CONSTITUTION: The capacity detection circuit comprises a switched capacitor circuit 15, sample hold circuits 16, 17, a differential amplifier circuit 18, a sensor drive circuit and a logic circuit.

CONSTITUTION:The raw water admitted into a denitrifying part 4 through a passage  12 for supplying of raw water 12 is intimately mixed with part of the nitrifying liquid  which circulates therein with the aid of agitating vanes of a small diameter to assume  an anaerobic state. The NOx in the nitrifying liquid performs reduction denitrification  reaction while consuming the org. components in the raw water as hydrogen donator  by the effect of denitrifying bacteria. The gaseous N2 formed by said reaction is released into the atmosphere. The other components in the org. components in the raw water circulate as circulating liquid in a nitrifying part 3. In the stage of circulating  while receiving the supply of oxygen by an aerator, said components are oxidized and decomposed by BOD oxidizing bacteria. The nitrogen components decomposed by  ammonia bacteria are nitrified to nitrous acid and nitric acid forms by the effect of nitrifying bacteria.

Title: Matte finishing of electrodeposition coating film
Inventor: SUMITOMO YASUO
IPC: C25D13/00
Filed: 1982-09-01
Abstract: PURPOSE:To apply fine and uniform matte fnishing to an electrodeposition coating film, by a method wherein an object to be coated is subjected to electrodeposition coating in an electrodeposition bath having a temp. higher than the glass transition point of binder resin and DC voltage is applied in an acidic treating liquid while using the object to be coated as an anode. CONSTITUTION:An object to be coated is subject to electrodeposition coating in an electrodeposition bath having a temp. higher than the glass transition point of the binder resin in an electrodeposition paint to form a soft wet coating film on the object to be coated. When this coated one is immersed in an acidic treating liquid, the surface of the coating film is dissolved. At the same time, an acid radical functioning as the curing agent of the binder resin is electrically introduced into the surface layer part of the coating film by applying DC voltage while using the object to be coated as an anode. By this method, difference is generated in contraction stresses of the surface layer part and an intermediate layer part when the coating film is baked and cured. By these synergistic effects, the surface of the final baked and cured coating film is made rough to perform matte finish.
