Title: Load sharing apparatus for 2-unit 1-shaft engine
Inventor: TOOSAKA SHIGERU
IPC: F02D25/00
Filed: 1982-07-05
Abstract: PURPOSE:To permit the rack position to be compared when the rack of a following engine is set at a prescribed position by keeping the revolution number instruction for a main engine always a little higher than that for the following engine and using a set potentiometer and a following potentiometer. CONSTITUTION:When the revolution number instructions for two units of engines 1 and 2 are given to governors 11 and 11', racks 13 and 13' move to the direction to increase the injection amount of fuel injection pumps 12 and 12'. If a little difference is generated between revolution number signals in this case, an unbalance in load share is generated, and the service life is shortened. Therefore, the revolution number instruction for a main engine 1 is set always a little higher than that for a following engine 2, and when the rack 13' of the following engine 2 is set at a prescribed position, the positions of both racks are compared with each other by a set potentiometer PT2 and a following potentiometer PT1, and if a difference is detected, a rack restricting hydraulic cylinder 15 is operated through an amplifier 17 and a solenoid valve 21, and shift of a level 10 to the increase side is restricted, and the rack 13 is set to the position 13'. Thus, load is equalized, and each burden onto the both engines are equalized.

Title: Photoelectric conversion element
Inventor: YOSHIDA TAKASHI
IPC: H01L31/04
Filed: 1987-05-14
Abstract: PURPOSE:To reduce a deterioration of the light due to the irradiation with the light by a method wherein an n-layer is formed by a-Si1-xNx and an i-layer composed of a-Si1-xNx whose (x) is smaller than that of the n-layer is laid between the n-layer and another i-layer with a view to increasing the initial photoelectric conversion efficiency even when the i-layer is thick. CONSTITUTION:An i-n interface layer film 5 composed of a-Si1-xNx is deposited on an i-layer film 4 of amorphous Si(a-Si); an n-layer film 6 composed of n-type a-Si1-xNx is deposited on the interface layer film. While a nitrogen content ratio x is kept at a definite value, the i-n interface layer film may be formed uniformly; it is desirable, however, to gradually increase the ratio toward the n-layer side between the i-layer film and the n-layer film. By this setup, an electric field in the neighborhood of the i-n interface is strengthened. Accordingly, it is suppressed that an internal electric field is weakened due to an incidence of the light on the i-layer film and the n-layer film; it is possible to prevent that an interface defect is caused due to the mismatching at a heterojunction between a-Si and a-Si1-xNx.

Title: Formation of thin film
Inventor: OIKAWA SHIGERU
IPC: C23C14/12
Filed: 1984-06-08
Abstract: PURPOSE:To form a high quality of org. matter by a simple method by placing org. matter as a vapor deposition source close to a substrate so that they confront each other, heating the org. matter under ordinary pressure, and depositing the resulting vapor on the substrate. CONSTITUTION:A boat 1 for a vapor deposition source contg. org. matter as a material 2 to be vapor-deposited is brought as close as possible to a substrate 3. The material 2 is evaporated by heating with an electric heater or the like under ordinary pressure, and the resulting vapor is deposited on the substrate 3 to form a thin film 4. Since the material 2 is brought close to the substrate 3, the substrate 3 is prevented from being excessively heated by providing a cooling mechanism. Fluorescein, rhodamine B, phenolphthalein or the like can be effectively used as the material 2.

Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To measure simply and highly accurately high level voltage supplied as a word line potential without resolving a package. SOLUTION: When a test mode TM is reversed from a Hi signal to a Lo signal, a transistor 5 is turned on only for a time delayed by a delay circuit 3, and gate voltage of a transistor 8 is boosted to the prescribed voltage.

Filed: 1989-05-10
Abstract: PURPOSE:To improve the deaeration of molten slug in the melting furnace for sewage sludge, etc. by disposing a slug port which penetrates vertically through the furnace floor of the furnace outer shell and is surrounded by a water jacket, and erecting cooling rods from the water jacket to protrude from the furnace floor. CONSTITUTION:The refuse 24 is melted in the burning chamber 25 to become the molten slug 31, which flows on the surface of the refuse 24 toward the slug port 23. The molten slug 31 then is cooled by the cooling rods 27 which are cooled by the cooling effect of the cooling jacket 26 to become stuck and grow around the cooling rods 27 to form a barrier 33 of solid slug 32. The barrier 33 dams the slug 31, and the slug 31 is deaerated while it is being dammed. When the growth of the barrier 33 reaches its limit, a gap is generated in the barrier 33 to allow the deaerated molten slug 31 to overflow from the gap into the slug port 23. By this constitution, the enough deaeration can be performed.

Title: Controller for induction motor
Inventor: TATARA SHINJI
IPC: H02P21/00
Filed: 1989-05-15
Abstract: PURPOSE:To produce torque accurately upon application of an actual load by providing means for operating voltage to be induced, means for detecting the difference between a voltage reference and the induced voltage, and means for correcting the difference. CONSTITUTION:A speed reference omega* and an actual speed omegar detected through a speed detector 12 for a motor 13 are compared each other and fed to a speed control section 1. A voltage reference E orthogonal to the axis of flux and an induced voltage E2 operated through multiplication of secondary flux reference PHI and the actual speed omegar are fed to a slip correcting section 17. Since the output voltage reference E is lower than the induced voltage E2 for a high slippage, a positive slip correction output is produced to increase the secondary constant. The secondary constant is reduced for a low slippage. By such arrangement, torque can be produced stably and accurately without causing over excitation or shortage.
