Title: Reverse thrust generator of asymmetrical gate double flux turbojet
Inventor: PASUKARU RARUDEI
IPC: F02K1/56
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To prevent the controllability of an airplane from being damaged by the change of lift of a wing if a gate is opened suddenly during flight by making the width of a gate positioned on a given side smaller than the width of a gate on the opposite side with reference to the rotating shaft of a turbo jet. SOLUTION: A reverse thrust generating device includes four turning gates 27, 37, wherein two gates 27 are placed above the normal position of an airframe on the ground and two gates 37 are placed below that. The width 25 of the upper gate 27 is smaller than the width 26 of the lower gate 37. Accordingly, during the reverse thrust operation, if the gate of the reverse thrust generator is put in the open position, air flow discharged upward is decreased so that even if the gate is accidentally opened, a bad influence on the controllability of an airplane can be lessened. Further, the front face 28 of each upper gate 27 is close to the vertical direction 29 so as to reduce the above bad influence. Accordingly, the flow of air discharged downward through a shaft opened by the opening operation of the lower gates 37 is increased.

Abstract: PROBLEM TO BE SOLVED: To restrain an edge breakdown phenomenon from occurring in an avalanche photodiode. SOLUTION: A photodiode is possessed of a pn junction which is formed in an u-InP multiplying layer 45 through a diffusion process which is carried out for the formation of a p<+> -InP diffusion layer 48 using an ohmic contact layer 46, provided with an inward gently inclined plane as a diffusion mask.

A second conductivity-type electrode 50 is formed on an exposed contact layer, and a first conductivity-type electrode is formed on the rear surface of a substrate 41. Therefore, an electrical field is more intense at the center region of a pn junction than at the edge region.  A diffusion process carried out for forming a guard ring or a partial charge sheet layer and an epitaxial growth process can be dispensed with, so that manufacturing process of avalanche photodiodes can be simplified.
