Abstract: PURPOSE:To easily control the amt. of carbon doped into a III-V compd. semiconductor without varying growth temp. even in the case of growth in many layers by introducing hydrogen radicals into a reaction tube when carbon is doped into the semiconductor during vapor growth with an organometallic compd. as starting material for the group V element. CONSTITUTION:When carbon is doped into a III-V compd. semiconductor during vapor growth with an organometallic compd. as starting material for the group V element, the amt. of hydrogen radicals introduced into a reaction tube under a low growth pressure of <=40Torr is varied. By this method, the amt. of carbon doped can easily be controlled. Unlike the conventional method by which the amt. of carbon doped is controlled by varying growth temp. this method does not require suspension of growth at the time of varying growth temp. and the time necessary for growth can be shortened. Impurities and crystal defects are not introduced into the interface during suspension of growth and the interface is kept clean.

Modes (alpha02) and (alpha03) are close to mode (alpha10). Mode (alpha02) has polarity at every angle of 90 deg., and mode (alpha03) at every angle of 60 deg.. For the purpose, coupler 3 is arranged at each circular measure where those vibrations are suppressed.

Title: Exhaust gas recirculation quantity control method for internal combustion engine
Inventor: KAWAI TAIYO
IPC: F02M25/07
Filed: 1989-05-24
Abstract: PURPOSE:To obtain the optimum EGR rate at low/medium-load areas and secure the output at the high-load area by calculating the EGR rate in response to the correction suction pipe pressure corrected in the present atmospheric pressure when the present suction pipe pressure is the preset value or above. CONSTITUTION:A control circuit 52 determines the EGR rate by an EGR valve 36 with the correction suction pipe pressure corrected in response to the atmospheric pressure detected by the suction pipe pressure only when the suction pipe pressure detected by a pressure sensor 13 is the preset pressure or above in the engine atmospheric pressure. At the pressure below the preset pressure on the other hand, i.e., in low/medium-load areas, the EGR rate is determined by the uncorrected suction pipe pressure (in the standard atmospheric pressure), and the optimum EGR quantity is determined. In this case, only the engine rotating speed detected by a rotation angle sensor 54 and the EGR rate based on the suction pipe pressure may be prepared. The optimum EGR rate in low/ medium-load areas is obtained, and the engine output in the high-load area, particularly near the fully opened area of a throttle valve, can be secured.
