Title: Thermal oxidation of semiconductor wafer
Inventor: KAI TETSUJI
IPC: H01L21/324
Filed: 1992-11-30
Abstract: PURPOSE:To realize a thermal oxidation method for semiconductor wafer in which a constant resistance can be attained over the entire surface of wafer while preventing n-type contamination by depositing a silicon based film on the surface of a semiconductor wafer by CVD prior to thermal oxidation processing. CONSTITUTION:Cleaning step proceeds in the order of light etching - SC-1 (ammonium hydrogen peroxide) cleaning for removing organic dust-SC-2 (sulfuric acid hydrogen peroxide) cleaning for removing metallic dust - light etching. SiO2 is then deposited on the surface of a silicon wafer by CVD. The silicon wafer is then cleaned and placed in a thermal oxidation furnace into which HCl, O2, N2 gases are introduced thus forming an oxide through thermal oxidation. This method provides a substantially constant sheet resistivity without causing n-type contamination of wafer regardless of the set position of wafer in the furnace or flow rate of oxidation gas.

Title: Resistance moisture meter for grain
Inventor: SATAKE TOSHIHIKO
IPC: G01N27/04
Filed: 1999-11-10
Abstract: PROBLEM TO BE SOLVED: To obtain a moisture meter in which the interval between a pair of electrode rolls is not affected even when impurities are put between the pair of electrode rolls without carefully selecting a grain as a sample by a method wherein, when a signal is output from a comparison part, a motor is rotated in a reverse direction of rotation in which the grain is discharged from between the pair of electrode rolle by a forward-and-reverse rotation changeover part. SOLUTION: A control device receives an output from a comparison part, and it reverses the direction of rotation of a pair of electrode rolls 5, 6. When the direction of rotation of the pair of electrode rolls 5, 6 is reversed, impurities which are put between the pair of electrode rolls 5, 6 are discharged from between the pair of electrode rolls 5, 6. For example, when a point in which the electrode roll 5 on one side is brought close to the electrode roll 6 on the other side is moved to the upper part along the circumference of the electrode roll 6 on the other side, i.e., the electrode roll 5 on one side is set in the high position, the impurities are discharged from the between the pair of electrode rolls 5, 6 along the circumference of the electrode roll in the lower position.  In addition, when the pair of electrode rolls are tilted as viewed in the longitudinal direction parallel to the center axis of a cylinder, the impurities are discharged from between the pair of electrode rolls 5, 6 due to their inclination and due to the action of the reverse rotation of the pair of electrode rolls.

Inventor: INABA NAOTO
IPC: H03K5/08
Filed: 1991-12-04
Abstract: PURPOSE:To set a correct threshold value following the fluctuation of an analog signal to be binarized even when it occurs. CONSTITUTION:When an analog signal is inputted to diodes 3, 4 via a coupling capacitor 1 and a buffer 2, the analog signal is detected as the ones of positive and negative polarity, and they are inputted to buffers 8, 9. The intermediate value of difference of the signals detected via the buffers 8, 9 and resistors 10, 11 is outputted to a buffer 12, and the buffet 12 outputs a threshold value signal setting the intermediate value of difference of fluctuation signals as the threshold value. When an analog signal is changed steeply, the signals of positive and negative polarity are also changed corresponding to the fluctuation of the analog signal by the function of a capacitor 16.

Abstract: PURPOSE:To attain medium access control and efficient call permission control at a high speed by employing burst level control. CONSTITUTION:An idle counter is subjected to increment by a drain rte time constant Td so long as a count of a peak rate counter 12 is zero. The idle counter 30 is cleared at all time when the count of the counter 12 is other than zero. The count from the counter 12 is given to an AND gate 32 and a flip-flop(FF) 34. The constant Td is given to the gate 32. A clock signal is given to the FF 34 as its input. An output of the gate 32 is given to the counter 30 as its input.
