Abstract: PURPOSE:To reduce the air duct diameter and to cut down the house construction expenses maintaining the prescribed working space for the subject rotary electric machine by a method wherein the surface of the air inlet and outlet of the outer case, whereon a cooling pipe group for an air cooler are provided, is formed into the cylindrical surface conforming to a stator frame surface. CONSTITUTION:A plurality of cooling pipe 13 group is arranged heading to the axial direction and placed in an outer case 14, and an air cooler 9 is provided in such a manner that the air inlet surface 15 and the air outlet surface 16 of the outer case 14 are forming a cylindrical surface conforming to the outer circumferential surface 17 of a stator outer frame 7. In this way, as the cooling pipe 13 is circularly provided in the circular outer case 14, the space in the outer case 14 is filled up without waste space, the distance W between the air outlet surface 16 and the air duct 10 is not narrowed at both ends of the air cooler 9 and the air cooler can be installed directly on the stator frame 7. Hence, as the same cooling airflow is maintained, fan power is reduced and a highly efficient rotary electric machine can be obtained.

IPC: B63B35/08
Filed: 1979-11-30
Abstract: PURPOSE: To prevent the structure from freezing and erosion by a method wherein on external plate made from a copper-nickel alloy is arranged on the external surface of the structure located on frozen water area.  
     CONSTITUTION: On the surface 13 of an inclined external plate adjoining the ice 12 of the external surfaces of the structure located on the frozen water area is arranged an external plate made from a copper-nickel alloy. Since the copper-nickel alloy is of high strength and of high erosion-resistance and moreover the ice does not attach to the surface of the alloy, erosion can be prevented. Simultaneously, since the ice does not attach to the structure even when the structure is jammed in a drift-ice, the effect of the drift ice force can be prevented.

Filed: 1992-05-22
Abstract: PURPOSE:To obtain an output coincident with an objective value at specified arrival time and to enable changing the objective value or the specified arrival time on the mid-way of an operation by changing the characteristics of a function generator in accordance with residual time up to the specified arrival time. CONSTITUTION:An input to be changed from the initial time t0 up to the final objective value like steps is imparted to a filter 10.

In order to set up the objective value at the time (te), all poles (r) are made disappear. Since the value of the pole (r) is changed from the vicinity of '1' to '0' so that the value of 1/(1-r) is gradually reduced up to the time (te), a smooth waveform completely coincident with the objective value (final arrival value) at the specified arrival time (te) can be obtained.

Filed: 1978-12-14
Abstract: PURPOSE: To perform alignment with high accuracy in an automatic mask aligning device, by causing a computer to process a signal showing the relative position of a mask and a wafer and control motors for moving the wafer or the mask depending on their relative position.  
     CONSTITUTION: The position of a target on a wafer and that of another target on a mask are detected by photoelectric converters or the like. A mask aligner 61 supplies a necessary signal to a computer 64 to perform calculation. The result of the calculation is applied to a piezoelectric inching mechanism to drive piezoelectric minute- step motors 681, 682, 683 for variables x, y, θ through the motor controllers 671, 672, 673 of the inching mechanism to displace the wafer or the mask. The relative position of the mask and the wafer is detected to rapidly drive the piezoelectric motors toward an objective position. When the motors have passed through the objective position, they are slowly reversed to set the water or the maks in the objective position. The mask is thus aligned with high accuracy.

Abstract: PROBLEM TO BE SOLVED: To take a water-edge design into consideration by providing a float structure, which moves with a tidal level, for a structure fixed to a sea bottom with the upper part projecting on a sea surface. SOLUTION: A first structure 10 has a lower part fixed to a sea bottom G and an upper part projecting on a sea surface S. The structure 10 which consists of a truncated cone portion 11 with almost the same height and an outer periphery wall portion 12 therearound, e.g. is formed to be gradually tapered toward the upper end and provided with an inside sea water area S1 communicated with a sea surface S.
