Inventor: YOSHIDA MASAYUKI
IPC: C23C22/08
Filed: 1994-04-15
Abstract: PURPOSE:To obtain the subject composition which can impart corrosion resistance to the surface of a metal by mixing a water-soluble polymer having a chemical structure represented by a specified formula with an acidic compound. CONSTITUTION:A water-soluble polymer represented by formula I [wherein X is H, hydroxyl, a 1-5C alkyl, 1-5C hydroxyalkyl, 6-12C aryl, benzyl, benzal, an unsaturated hydrocarbon group or a group of formula II (wherein R<1> and R<2> re each H, hydroxyl or a 1-5C alkyl); Y<1> and Y<2> are each H, or a group Z represented by any one of formulas III and IV (wherein R<3> to R<7> are each a 1-10C alkyl, or a 1-10C hydroxyalkyl); the average number of groups Z is 0.2-1.0; and (n) is 2-50] is mixed with an acidic compound (e.g. phosphoric acid) to obtain the objective composition. This composition is dissolved in a specified amount of water to prepare an aqueous surface treatment solution having a polymer concentration of 0.01-20g/l, an acid ion concentration of 0.1-30g/l and a pH of 2.0-6.5. This solution is heated to about 15-90 deg.C, and a metallic material is immersed in this solution for about 5-60sec, washed with water, and dried by heating to form a polymer film on the surface of the material.

Title: Production of formed active carbon
Inventor: OOYABU MIKIO
IPC: C01B32/384
Filed: 1980-06-10
Abstract: PURPOSE: In the production of active carbon from coal, the depolymerization product of coal is used as a raw material to be formed, made nonfusible, carbonized and activated to enable the melt formation and produce the high-quality coal active carbon with reduced fluctuation in properties.  
     CONSTITUTION: Coal such as bituminous or brown coal is crushed, mixed with a hydrocarbon solvent such as the medium fraction of coal tar oil and dissolved with heat under pressurized hydrogen. The coal depolymerization product resulting from partial hydrogenolysis becomes thermally unstable, when the reaction is insufficient and causes difficulty in uniform dissolution to expand the fluctuation in the particle and shape size. When the reaction goes excessively, the activation requires a long time. Therefore O/C of the depolymerization product is adjusted to about 0.01W 0.07. Further, the softening point is made to 160W250°C to facilitate the process for making formed product nonfusible. Since the depolymerization product melts uniformly, it can be made into balls at the melting state. The formed product is made nonfusible by air oxidation and subjected to carbonization and activation and they may be effected simultaneously.

Filed: 1979-06-18
Abstract: PURPOSE: To provide a fuel consumption meter which enables economical running by computing mileage per unit fuel consumption from fuel consumption signals transmitted from the level gauge of a fuel tank and mileage output signals.  
     CONSTITUTION: A transmitter 3 which outputs the signals of traveled distance is connected to the axle of a motor vehicle and a transmitter 6 that outputs the quantity of consumed fuel is connected to a level gauge in the fuel tank of the motor vehicle. When the motor vehicle travels, output from the transmitter 3 rotated by the axle is integrated and stored in a memory circuit 8 while the quantity of consumed fuel is introduced to the memory circuit 8 and an arithmetic circuit 9 as the output signal of the transmitter 6. The arithmetic circuit 9 computes quantity of consumed fuel divided by covered mileage, determines mileage per unit fuel consumption by erasing the integrated value of mileage in the memory circuit 8 each time an output signal from the transmitter 6 provided to the level gauge is received, and displays a value at that time on an indicator 10.

Title: Flow amount calculating method at dam or dam area
Inventor: KUBOTA SATORU
IPC: G06G7/48
Filed: 1978-06-28
Abstract: PURPOSE:To eliminate the abnormal value of the storage change amount and thus to increase the  accuracy of the flow amount calculation by giving a comparison between the average value of the  storage change amount calculated from the change of the water level at the upstream side and the  value obtained by multiplying the allowance change range set by the hydralic conditions by the  storage change a mount. CONSTITUTION:The water level change time t plus the average mount of change dv/dt of the  storage amount V corresponding to the water level change are obtained for the dam through  averaging circuit 6. Comparison reference value B is obtained by multiplying the average amount  obtained above by allowance change range K+1 through multiplier 20, and the storage change  amount calculated this time is compared 21 with value B. And in case value B is larger than the storage change amount, the average value including the storage change amount is obtained to be  then added with the average value of discharge amount QO through adder 13 in order to obtain  flow-in amount QI. In case storage change amount dv/dt calculated is larger than the reference  value, dv/dt is shunted to memory 24, and the storage change amount to be obtained next is  compared with the average value of the amount shunted in memory 24. In this way, the transient  abnormal value of the storage change amount caused by the outer disturbance of the water level  due to the waves can be eliminated, thus increasing the calculation accuracy of the flow amount.

The phase detector 8 detects a component signal synchronized with the magnetizing current in the detection signal from the photodetector 5 and the phase detector 9 detects a component signal synchronized with a component which is shifted, for example, by 90 deg. phase of the magnetizing current in the detection signal from the photodetector 5 and outputs it to a computing element 10. The computing element 10 finds the amplitudes of the components and the phase difference and outputs them to a differentiator 11 to detect the defect. Consequently, the defect of the ferromagnetic object of flaw detection can be detected with high accuracy.
