Filed: 1979-10-03
Abstract: PURPOSE: To effectively cool a bent part of a transition piece which connects a combustor of a gas turbine and turbine blades by providing intake holes in the bent part and flowing a stagnation part on the outside of the piece.  
     CONSTITUTION: A combustor 3 of a gas turbine which includes a compressor 1 and a turbine 2 is constituted of an outer cylinder 4, an inner cylinder 5, a fuel nozzle 6, and a transition piece 7. Combustion gas 8 generated in the combustor inner cylinder 5 is conducted to the first stage stationary blade 9 of the turbine 2 through the transition piece 7. In this case, multiple intake holes 22 are bore on a circumference of a back side bent part 20 of the piece 7, and a guide plate 25 is provided on its outside. Being thus constituted, air 23 is conducted to the intake holes 22 through the guide plate 25 and the piece 7 and to the inside of the piece, and then, the conducted flow of air flows down along an inner wall surface. By doing so, air in the stagnation part 19a starts to flow to improve cooling effect.

Title: Inspecting apparatus for leakage
Inventor: SOMEYA KATSUYA
IPC: G01M3/00
Filed: 1989-05-19
Abstract: PURPOSE:To inspect leakage by a method wherein after inspection vessels are set to specified pressure by a pneumatic source, it is isolated from the pneumatic source by control valves to detect differential pressure. CONSTITUTION:When small leakage is to be inspected, the inside of inspection vessels 6,7 is set to specified pressure by a pneumatic source 1 and control valves SV1, SV2 on the side of the pneumatic source 1 are closed. After specified time has elapsed, air admission occurs toward the inside an object 4 to be inspected if there is leakage in the object 4. Accordingly pressure difference occurs between the inspection vessel 7 on the side of a standard reference item 5 and the inspection vessel 6 on the side of the object 4 to be inspected wherein the pressure difference is detected by a pressure difference sensor 10 to indicate the existence of the leakage. If there is no small leakage, air pressure is supplied to the vessels 6,7 from auxiliary pneumatic sources 13, 14 on the respective paths. If there is large leakage at this time, air admission occurs only by a volume wherein the volume of the standard item 5 is subtracted from the volume of the vessels 6,7 on the side of the standard item 5 so that there is pressure difference between the vessels and 7. This pressure difference is detected by the sensor 10 to determine the existence of large leakage.

Abstract: PURPOSE:To make the boosting voltage generating circuit resist the level variation of an output by providing the circuit with a charging pump type voltage boosting means and a load means for changing a load state in accordance with a control input level and branching a part of an output from the voltage boosting means. CONSTITUTION:Since the load of a reference voltage generating circuit (c) is only the capacity load of the gate of a MOS transistor (TR) 1 in an output voltage controlling load circuit (a), constant voltage elements in the circuit (c) are matched with that of a charging pump circuit (b).

When a main power supply charging pump capacity is balanced with output voltage controlling load leakage, the output is fixed. In a stable state, both forced and sinking currents are balanced with each other, and even if the output side is varied due to any reason, the forced or sinking current is allowed to flow so that the changed voltage is returned to the original set voltage in returned to the original set voltage in accordance with the variation and the output is turned to the set voltage.

Filed: 1985-06-12
Abstract: PURPOSE:To attain the locking of focus servo with high accuracy by moving an objective lens in the focusing direction while the lens is vibrated minutely in the focusing direction or in the tracking direction. CONSTITUTION:An output of an adder 3 is a superimposition between a minute DC voltage and a minute AC voltage by an AC signal oscillator 1 and a bias signal generator 2 at focus servo locking state and a focus magnetic circuit 6 is driven by a current proportional to the voltages. The objective lens is driven while the friction between a moving member and a bearing transits from the static friction into the kinematic friction, and when the output of the bias signal generator 2 starts increasing, the objective lens is moved smoothly accordingly in the focus direction while being fluctuated minutely. Thus, a focus state detection circuit 7 discriminates the focus servo locking direction, changes over an output signal of a changeover circuit 4 from the output of the adder 3 into an output of an amplifier 8 to lock the focus servo.
