Title: Gland steam generator control method and device
Inventor: IMAIZUMI TATSUO
IPC: F22B35/14
Filed: 1978-04-05
Abstract: PURPOSE: To prevent gland steam reduction in pressure and steam at the point  gland steam source is changed, by conrolling the set value of a regulator varying  according to the output power of a steam turbine.  
     CONSTITUTION: A set value of a regulator 30 is controlled to read higher in comparison with lower power put from a steam turbine 2 or the related equipment, decreasing with increase in the power of the equipment. As the power is lower, a valve opens wider to allow set pressure of the gland steam generator 5 higher. Before and after the start of the turbine 2, a great amount of calorific power is sent from a steam pipe 12 to the steam generator 5. As the turbine 2 puts out power increasingly, air bled flows more from a bleed pipe 14 to the steam generator 5 and  steam from the steam pipe 12 to the generator 5 reduces in amount. Immediately  after the start of the turbine 2, potential heat in the gland steam generator 5 rises  high, that frees from lack of steam generated.

Abstract: PROBLEM TO BE SOLVED: To conduct simple, highly accurate sensorless control of a synchronous motor, with only two current sensors, regardless of the presence of salient polarity. SOLUTION: In this method (apparatus), the angle of a rotor θ' is computed based on detected current values In-fb, Iv-fb and voltage command values Vu, Vv of two phases of a three-phase brushless DC motor 1 and by using the computed angle of a rotor θ', the motor 1 is controlled with 180-degree sine wave.

Title: Projector
Inventor: MATSUI YOSHIYA
IPC: G03B21/28
Filed: 1978-04-05
Abstract: PURPOSE: To provide a projector of less loss of quantity of light by providing a polarizing beam splitter between an object and a lens array and providing a device of changing the deflection direction to the splitter and mirror face.  
     CONSTITUTION: Luminous flux emitting from an object 1 is made to linearly polarized light by a polarizer 9. When the exit luminous flux is circularly polarized light, the light passing through the polarizer 9 becomes half. The linearly polarized light transmits through a 45° polarization beam spliiter 2 of the vibration face equal thereto and transmits through λ/4 plate 10 via bar lenses 3, thereby becoming circularly polarized light and converges onto a mirror 4. The image is reflected from the mirror 4, again transmits through the plate 10, thereby becoming the linearly polarized light of the vibration face orthogonal to the linearly polarized light. This is then totally reflected by the splitter 2 and converges onto image plane 5. When the exit luminous flux from the object 1 is circularly polarized light, 1/2 of the luminous flux is transmitted to the image plane 5 and may be made twice that when the exit luminous flux of the time when an ordinary semi-transparent mirror without polarization is used is transmitted to the image plane 5.

IPC: D01H13/22
Filed: 1984-03-02
Abstract: PURPOSE:To improve the response of correcting the thickness of a sliver responding to the long-term thickness variation, by determining the relationship between the thickness and the weight of a sliver from the past data, and calculating the revised target value of the feed-back system from the measured weight. CONSTITUTION:The sliver 1 delivered from a carding engine is drafted with plural draft roller set 2, 2, collected by the collecting trumpet 3, and collected through the calender roll 4 to the can 5.

Title: Capacitor discharging ignition apparatus with electronic timing control
Inventor: KATADA HIROSHI
IPC: F02P5/155
Filed: 1979-04-06
Abstract: PURPOSE:To obtain a stable performance even at low speed by making an electronic timing control circuit function ineffective when power voltage drops to a given value or below. CONSTITUTION:A power voltage drops and an output voltage of an electronic timing control circuit 2 also drops to the power voltage or below at a low rotational frequency which is capable of operating the electronic timing control circuit 2 erroneously, therefore a signal from the electronic timing control circuit 2 is blocked by a zener diode ZD2 and hence is not transmitted to a gate of a firing thyristor 6. In such a case, on the other hand, a signal from pulser coil 3 is applied directly to the gate of the thyristor 6 by way of a resistance R2 and a diode D5 and thus triggers it, therefore a stable firing operation is obtainable at a position before the spark advance.
