IPC: H03G3/12
Filed: 1982-06-29
Abstract: PURPOSE:To obtain a sound volume adjusting circuit with a small sound of noise and a large permissible input and with high accuracy even if attenuation is large, by changing the amount of feedback and attenuation with one variable resistor in common for an audio amplifier. CONSTITUTION:An output attenuation resistor R3 is inserted between an output side of a non-inverting amplifier 3 and an output terminal 2 and a variable resistor 4 (R4 in resistance value) grounded with a slider section is inserted between the output terminal 2 and an inverting input of the non-inverting amplifier 3. The variable resistor 4 is split into a resistor r1 part and a resistor r2 part with the sliding of the grounded slider section. The resistor r1 part is a part of a feedback resistor and the resistor r2 part is a part of an output attenuation resistor. That is, the overall gain (attenuation) G is changed by sliding the grounded slider of the variable resistor 4 for changing the ratio of the resistance values r1:r2.

Abstract: PURPOSE:To enable performing a stable phase control by attaching a stabilization circuit, which compares the output of a sawtooth wave voltage with the specified voltage of the output to obtain a specified sawtooth-wave voltage, to a sawtooth-wave generation circuit. CONSTITUTION:An AC supply voltage is full-wave rectified by a bridge rectifier circuit 5, of which full-wave rectified current is applied to a zero-cross detection circuit 7. Then, as a result of comparison with a given voltage, a detected pulse corresponding to a zero cross is outputted from the zero-cross detection circuit 7. A sawtooth-wave voltage is generated, when the zero-cross detected pulse is applied to a sawtooth-wave generation and detection circuit 8 composed of a sawtooth-wave generation circuit and a stabilization circuit. When the sawtooth-wave voltage and an input signal are received, a phase-angle control pulse is outputted from a phase-angle control circuit 9. Subsequently, when the level of the input signal is varied, a phase angle changes and power applied to a load is subjected to a phase control.

For instance, when (011)2divided by (010)2 is executed in a real number operation, (001.1)2 is obtained. On the other hand, in an integer bit shift operation, (001)2 is obtained. In an error arithmetic model means, (0.0111...)2 is subtracted from the result of the real number operation (001.1)2, and thereafter, its result is rounded. Accordingly, (001)2 is obtained as an output. That is, the same result as the case when the integer bit shift operation is executed is obtained.

Title: Method and composition for forming phosphate coating
Inventor: BURAUN KEBIN
IPC: C23C22/36
Filed: 1981-07-15
Abstract: Phosphate coatings are formed on ferrous surfaces by dipping or flooding the surfaces with an acidic zinc phosphate solution containing a high zinc content, nitrate or other oxidising agent incapable of oxidising ferrous to ferric and a low controlled amount of chlorate or other oxidising agent capable of oxidising ferrous to ferric such that the solution contains 0.05 to 1% dissolved iron. This process can be achieved but using novel replenishment and make up solutions. The initial make up solution may be free of chlorate but the replenishment solution will contain a low amount of chlorate or other suitable oxidising agent. The phosphating solution preferably has a zinc/phosphate ratio in the range 0.8-4, a Zn/Ca ratio of 1-4 and a total acid/free acid ratio of 5-9. Use of the solution gives rise to reduced sludge production. The solution may contain conventional additives such as Cu, Co, Ni, fluorides, urea. The surfaces to be treated may first be pickled, degreased then preactivated with either hot water or a titanium ortho- phosphate dispersion.
