Title: Nozzle for booster engine
Inventor: NAKABASHI KAZUHIRO
IPC: F02K9/97
Filed: 1982-08-18
Abstract: PURPOSE:To facilitate to reform the existing nozzle with a simple mechanism, increase a propulsive efficiency and permit to increase a thrust by a method wherein a valve, opening and closing by a pressure difference between the outlet pressure of the first stage nozzle and an atmospheric pressure, is provided at a step part between first and second stages in the device equipped with the nozzle of two stages. CONSTITUTION:The outside pressure Pa is higher than the inside pressure k1Pe1 during launching and low-altitude flying, therefore, the valve 3 is kept in an opened condition, atmospheric air is introduced into the nozzle 2 through a step- like clearance and the generation of the thrust is performed by the nozzle 1 principally. Next, the pressure Pa is decreased as the flying altitude is increased, however, the outlet pressure of the nozzle 1 is constant, therefore, the valve 3 is opened automatically by the difference between the inside and outside pressures of the valve 3 when the altitude, in which the pressure K1Pe1 is higher than or equal to the pressure Pa, is achieved. Thereafter, gas, generated in a combustion chamber, flows through the nozzle 1 and the nozzle 2 fully, whereby, the nozzles operate as the nozzle having a capacity corresponing to the nozzle having a large opening ratio.

Title: Differential voltage detecting circuit
Inventor: KAI YOSHIO
IPC: G01R19/165
Filed: 1979-11-08
Abstract: PURPOSE: To easily settle troubles caused by erroneous operation by making a reference component of control signals correspond to the part of a differential voltage detector which constitute a reference component.  
     CONSTITUTION: A control signal from an automatic voltage regulator 10 is left as it is. Then a control signal from a magnetic field regulator 14 is once conducted to  a dummy resistance 17 of the equal value to saturable converter control winding 4-3  and a control voltage VM from a regulator 14 is created at a point connected to the  winding 4-3. After these steps, a control voltage VA from the regulator 10 currently in operation together with the control voltage VM is observed with a balance meter 16. The voltage VA is conducted to the second terminal of a meter 16 through the intermediary of terminals 10, 9 for an automatic/manual operation change-over switch 15. As a result, the meter 16 shows a clockwise oscillation, when VA is lower than VM. At the same time, it indicates 0 when VA equals VM and it shows a counterclockwise oscillation when VA is higher than VM. Through observation of these indication, the regulator 14 is operated in such manner that the needle of the meter 16 may be set at a center 0 position. Thus it is possible to easily settle troubles caused by an erroneous operation.
