Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a semiconductor light-emitting device, in which time required for increasing or decreasing temperature is reduced and throughput is improved. SOLUTION: In a method, a GaN buffer layer is formed at 530 deg.F on a sapphire substrate, an N-type GaN layer is grown, while 3.9eV light is being applied at 800 deg.F that is the growth temperature of an InGaN layer. Then 800 deg.F is maintained, light of 4.2eV is applied and an N-type AlGaN layer is grown. The InGaN layer is grown without applying light, a p-type AlGaN layer is grown while 4.2eV light is being applied, and a p-type GaN layer is grown, while 3.9eV light is being applied. Thus a constant light or light with an energy that is equal to or more than a band gap as needed at a low growth temperature for growth is applied.

Then the frequency is divided into one over horizontal scanning line number by the 2nd binary counter 3 and the result is given to a memory 5 storing how the N kind of horizontal scanning signal patterns are arranged in one frame. The output and the output of the counter 2 are given to a memory 6 storing the N kinds of horizontal scanning signal patterns themselves to output one horizontal scanning signal pattern. The output is latched by a latch 7 and the output triggered by the output of the inverter 4 is displayed by a DA converter 8.

Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a pneumatic type booster which can obtain rapid brake control and also can lower fluctuation of brake hydraulic pressure, by shortening reaction time when a solenoid is operated. SOLUTION: The maximum relative movement (b) against a plunger 33 by the solenoid 37 of a cylindrical member 34 when automatically performing brake operation by a command from the outside, is set shorter than the maximum movement (a) of the cylindrical member 34 by engagement with the plunger 33 when performing normal brake operation by the pedal operation of a driver.
