Title: Microscopically processed surface treatment agent
Inventor: KIKUYAMA HIROHISA
IPC: C23F1/24
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To reduce the difference in the etching rate of the oxide films having different film forming methods and conditions, or different impurity density by a method wherein a treatment agent, containing specific weight ratio of fluoric acid and ammonium fluoride, is used. SOLUTION: An oxide film is formed by wet oxidizing a silicon wafer. Then, after a resist film has been formed into pattern shape, As is ion implanted, and an As-containing layer is formed by heat treatment. Pertaining to the two kinds of thermally oxidized films containing As as impurities and not containing As as impurities, etching treatment is conducted using a treatment solution having HF density of 0.1 to 8wt.% and NH4 F density of 40 to 47wt.%. The etching rate ratio comes close to 1.0 as the NH4 F density goes up becoming more desirable, and crystal is liable to be deposited. Therefore, it is necessary to control temperature in a highly precise manner.

Title: Speed control method for dc motor
Inventor: SUZUKI NARIHIRO
IPC: H02P7/298
Filed: 1985-10-16
Abstract: PURPOSE:To reduce loss due to line resistance by determining the starting point of field control by a speed signal. CONSTITUTION:When a motor-voltage signal is smaller than a field-weakening point setting signal set by a variable resistor RH1, an output from an amplifier OA1 is brought to a negative value, and interrupted by a diode D1. Consequently, field currents only corresponding to a signal set by a variable resistor RH2 for setting a maximum field flow. When the motor-voltage signal is made larger than the field-weakening point setting signal, the output from the amplifier OA1 works so as to deny the maximum field signal, and field currents are reduced. On the other hand, an amplifier OA3 extracts a speed signal larger than a value set by a variable resistor RH4 for setting a correction point, and applies it as an input signal to the amplifier OA1. Accordingly, motor voltage in a field control region can be kept at a value as high as possible, thus reducing power loss by line resistance in a motor.

Title: Freeze circuit
Inventor: NAKAHIRA RIICHI
IPC: H04N5/44
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a freeze circuit which never displays an image having its deteriorated receiving C/N even when the receiving C/N is slowly deteriorated by sorting the peak value of the detected receiving C/N into a prescribed number of stages and setting the threshold of the freeze circuit based on these sorting results. SOLUTION: The peak value of the C/N detection voltage is detected by a peak value holding circuit 1. The peak value detected by the circuit 1 is sorted into four stages by the comparators 11 to 13, i.e., the C/N is hither than 12αβ, higher than 10αβ and lower than 12αβ, higher than 8αβ and lower than 10αβ, and lower than 8αβrespectively. Then a signal showing one of these four stages is outputted to an analog multiplexer 15 via a gate 14 based on the signals outputted from the comparators 11 to 13. The multiplexer 15 selects one of C/N voltage levels 10αβ to 4αβbased on the signal received from the gate 14 and outputs this voltage level as threshold.
