Title: Guiding device of flying body
Inventor: YAMAZAKI NORIO
IPC: B64C13/18
Filed: 1983-01-13
Abstract: PURPOSE:To lock the titled device for a short time even if transmission frequency different from that of semiactive homing guide is used at the time of active homing guide by setting up searching frequency in accordance with objective Doppler frequency. CONSTITUTION:Objective speed information 17 from a Doppler frequency tracking circuit 5 is stored in a storage circuit 16 while being updated by the newest contents momently. An arithmetic circuit 14 calculates the objective Doppler frequency on the basis of the objective speed information 17 stored in the storage circuit 16 and transmission frequency information 13 from a transmitter 10. Receiving the objective Doppler frequency, a searching frequency setting circuit 15 sets up searching frequency in accordance with the objective Doppler frequency. Consequently, a narrow band tracking filter 6 locks the objective Doppler frequency for a short time. Thus, the titled device can be locked for a short time even if the transmission frequency different from that of the semiactive homing guide is used at the time of active homing guide.

Title: Auxiliary control apparatus for turbine power generation plant
Inventor: CHIBA JIROU
IPC: F01D21/00
Filed: 1978-01-18
Abstract: PURPOSE: To prevent water hammering generated in turbine power generation plant by forming a regulation valve in such a manner as to be opened or closed as desired, slowly or quickly.  
     CONSTITUTION: For example when the turbine load is less than 25 percent, a push botton is operated to excite solenoid valves 20 and 21 so that a valve 22 is opened from C through B while closed at A, and a valve 21 is opened from B through A while closed at C. Thus, an air set 22 forces a level adjusting valve 17 to be fully closed and the drain of a feed heater 13 is controlled by a water level adjusting valve 18. When the turbine load exceeds 25 percent, allowing control with a valve 7, the push button 24 is operated to cut excitation off the valve 21, so that the valve is opened from A through C while closed at B. Then, control air is relieved from the port C to release the valve 17. Prior to this, a needle valve of a capacity tank 23 is controlled to delay the speed of the valve 17 from the full closure to a given opening. On the other hand, a timer is operated to cut excitation off the valve 20, so that the valve is opened from A through B while closed at C, whereby a switch is made to a control signal of a level adjusting gauge. With such an arrangement, the small opening of the valve 17 allows the drain of a feed heater to be recovered gradually, thereby preventing water hammering.

Abstract: PURPOSE:To improve the accuracy of stop by installing magnets on a track and by utilizing attracting force and repelling force as a driving force to the fixed stop point which is created between the magnets and superconductive magnets on a car. CONSTITUTION:Two electromagnets 3 for fixed point stop are installed on a track 1 in the order of N-pole and S-pole on the left side of the traveling direction of a vehicle 2 and also two other electromagnets in the order of S-pole and N-pole on the right side, and the electromagnets 3 are electrified when the vehicle 2 travels and the reference position A on the vehicle comes to the position C which is located at a distance of one pole pitch from the fixed stop point B to the approaching vehicle. Then, the direction of thrust due to the magnetic forces between the electromagnets 3 and the superconductive magnets on the vehicle becomes the same as the traveling direction of the vehicle 2 and, when the vehicle reaches the fixed stop point, the thrust becomes zero. After passing fixed stop point B, the direction of the thrust becomes reverse to the traveling direction of the vehicle 2. By doing this, the thrust which always directs the reference position A of the vehicle at the fixed stop point B can be obtained.

As a result, in preparing a coal slurry, the power required for pulverization can be minimized and also wearing of pulverized parts can be minimized. Moreover, during combustion of the coal slurry, the limestone in powdery form is heated and decomposed due to its inclusion in the coal slurry, and the decomposition product is effectively bonded with the sulfur components in combustion gas. Thus, desulfurization effect is exhibited.
