Title: Burst agc circuit and burst agc control method
Inventor: WATABE HIDEO
IPC: H04B7/005
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To provide a burst AGC circuit and a burst AGC control method for reducing the power consumption of a variable gain amplifier in a state that a burst signal is not present, and operating satisfactory AGC control from the first part of the burst signal. SOLUTION: A burst presence or absence discriminating part 10 outputs a reception discrimination signal (L level) 10a for designating an AGC operation mode in a burst signal presence period (burst receiving timing), outputs the reception discrimination signal (H level) 10a for designating an AGC non- operation mode in a non-receiving(non-signal) period, and moreover, outputs the reception discrimination signal (L level) 10a for designating the AGC operation mode at a point of time a little before the arrival of the next burst receiving timing. A gain setting part 7 in an AGC control part 4 sets the gain of a variable gain amplifier 3 based on reception signal intensity detected by a reception level detector 5 in the AGC operation mode, and sets the gain of the variable gain amplifier 3 to the minimum value in the AGC non-operation mode.

Filed: 1994-01-25
Abstract: PURPOSE:To correct lens distortion by dividing a reticle such that the nonlinear component of a design pattern formed thereon can be approximated by a linear component and exposing the divided reticles independently thereby forming one design pattern on a semiconductor substrate. CONSTITUTION:An approximate pattern 2 is determined such that a design pattern 1, including a linear component and a nonlinear component, is entirely represented by linear components and then a reticle 3 is divided into four such that an approximate pattern 2 thereof can be obtained. Each reticle 3A-3D is then subjected to positional correction such that the best superposition of the reticles 3A-3D and a semiconductor substrate can be achieved based on the distortion information of lens or the like before a design pattern is exposed on the semiconductor substrate. Consequently, correction of linear component can be applied to correction of nonlinear component and lens distortion can be corrected for the nonlinear component of design pattern.

Title: Selective anode oxidation method
Inventor: KATSUKAWA KIMIAKI
IPC: C25D11/32
Filed: 1978-01-25
Abstract: PURPOSE: To oxidize selectively a n-type layer by stopping the oxidation when anode oxidation  reaction reaches a p-type layer with the n-type layer taken as an anode and an increase rate of a  voltage between the anode and cathode becomes higher than that of the oxidation reaction.   
     CONSTITUTION: On n-type GaAs 13, p-type GaAs 12 and n-type Ga 0.8 Al 0.2 As 11 are epitaxy- formed. The surface, flank and reverse surface are all covered with resist mask 9 and light- irradiation oxidation is carried out with only layer 11 fitted with an anode electrode. Quarz container 3 is filled with a mixed solution of water, tartaric acid and ethyl glycol, and platinum electrode 7 and wafer 4 is set and then applied with constant voltage 1. As the formation of an oxidized film in film 11 starts, a voltage drop in the oxidized film becomes larger and is measured by  voltmeter 10, and its rising rate is observed by eyes. At this time, the wafer should be irradiated  sufficiently by projector 6 to prevent the (pn) junction between layers 11 and 12 from being applied with an overvoltage reversely during the oxidation, thereby removing the oxidized film by  hydrochloric acid. When the reaction reaches the p-type layer, the bias becomes opposite in direction to increase the voltage rasing rate. Stopping the oxidation at this time removed only n-type  layer 11.
