Method for controlling antenna and electronic device thereof

In a substrate processing method, a cleaning process is performed at a first temperature to remove a portion of a cumulative layer that is deposited within a chamber by deposition processes (step 1). The deposition processes are performed at the first temperature on a plurality of substrates within the chamber respectively (step 2). The step 1 and the step 2 are performed alternately and repeatedly.

Substrate processing methods

The present invention relates to a synthesis method of preventing the formation of impurities and byproducts in the synthesis of tenofovir disoproxil fumarate (Teno-DF) used as a medicine for hepatitis B and HIV treatment due to its function to promote bioactivities. In the synthesis method of the present invention, an ion-exchange resin (Dowex 50W hydrogen form, sulfonic acidic cation exchange resin) is used to enhance the yield and purity of the compound. The present invention also relates to a method of preparing an oral dissolving film dosage form in the manufacture of a medicine using the tenofovir compound with high purity obtained by the synthesis method of the present invention as an effective ingredient.

An image forming apparatus is configured to reduce a velocity fluctuation of a rotating body by reducing the AC velocity component of the rotating body. The image forming apparatus may include an image bearing body with a surface on which a toner image is formed; a driving motor configured to drive the image bearing body according to an input signal; and a controller configured to control the driving motor to output a motor output velocity at a period equal to that of an AC velocity component of the image bearing body. A velocity control method for the rotating body includes sampling a continuous motor input signal at a period equal to that of an AC velocity component of a rotating velocity of the rotating body. The sampled signal is transmitted to a driving motor that drives the rotating body, which is driven based upon the discrete motor input signal.

Image forming apparatus and velocity control method of rotating body thereof
