Inventor: DRAGONE CORRADO

Abstract: This invention is an optical Multiplexer/Demultiplexer, built from a plurality of optical waveguides (106-108, 101-105). Each waveguide (101-105) differs in length from its neighboring waveguide by a predetermined amount. The waveguides are strongly coupled to one another at their respective ends, and substantially uncoupled therebetween, allowing for high efficiency. 
     As the wave propagates along the tapered region of the waveguides of waveguide array (115), it is gradually transformed into five separate uncoupled waves, with such tranformation causing near zero higher order mode generation. Each of the five uncoupled waves will then propagate along its respective waveguide until reaching waveguide array (113). 
     At waveguide array (113), the five waves are gradually coupled back into a single propagating wavefront, which emanates toward waveguide array (114). Since l is an integer multiple of λ₀, the constant phase difference φ between adjacent waveguides is preserved. Thus the wave emanating from each of the waveguides of waveguide array (113) is phase shifted by φ from the wave emanating from its neighboring waveguide. 
     The five waves will combine to produce a single wavefront which propagates in a direction that corresponds exactly to the direction along waveguide array (112) from which the wave was launched. More particularly, a wave launched from waveguide (106) will be directed by waveguide array (113) toward waveguide (109), since waveguides (106) and (109) are disposed in corresponding positions of their respective waveguide arrays (112) and (114). Similarly, waves which are launched from waveguides (107) or (108), will be directed by waveguide array (113) at waveguides (110) and (111), respectively. This is due to the fact that waveguides (107) and (110) are located in corresponding positions of their respective waveguide arrays (112) and (114), as are waveguides (108) and (111).

Abstract: A DRAM comprising word lines parallel to X-axis and bit lines parallel to Y-axis wherein the memory cell consists of a transistor and a stacked-type charge-storage capacitor is disclosed. The storage node electrode of the stacked-type charge-storage capacitor is formed to project on the surface of the silicon substrate a rectangle of which the major sides are oblique to X-axis and Y-axis or a pattern consisting of at least two different rectangles. Thereby the perimeter of the storage node electrode becomes more than that in the prior art. This enables the realization of charge-storage capacitors having larger capacitance value than in conventional DRAM under the same manufacture conditions. This effect is marked under the conditions where the film thickness of the storage node electrode is more than 1/2 of the minimum feature size, and the distance between two adjacent storage node electrodes is equal to the minimum feature size.

The seal ring (25, 35, 45, 55) is made of rubber different from the rubber of the cap body (26, 36, 46, 56) and has a high heat resistance and a sufficient elasticity. When the cap (21, 31, 41, 51) is mounted on the opening (14), the seal ring (25, 35, 45, 55) engages the inner peripheral surface of the opening (14) to provide a seal against dirt, dust and water. Alternatively, the seal ring (25, 35, 45, 55) may be made of rubber of the same quality as the cap body (26, 36, 46, 56). In this case, the hardness of the seal ring (25, 35, 45, 55) is rendered to be less than that of the cap body (26, 36, 46, 56).

Abstract: An object of this invention is to provide a compressor in which the number of components and the number of manufacturing steps are reduced, and a compression element is prevented from being displaced in the casing, whereby the air gap between the rotor and the stator of the motor is held unchanged at all times. In a compressor, a connecting cylinder 11a is formed on the casing 1 having a connecting opening 11 such a manner that it is extended from the connecting opening outwardly of the casing, and an inlet tube 6 has a first press-fitting portion 61 which is press-fitted into a refrigerant sucking hole 31a and a second press-fitting portion 62 which is press-fitted into the connecting cylinder 11a. The inlet tube 6 is fixedly secured to the casing 1 by press-fitting it into the refrigerant sucking hole 31a and the connecting cylinder 11a, whereby the compression element 3 is prevented from being displaced in the casing. The compression element 3 is prevented from being displaced in the casing 1 by means of the inlet tube 6. Therefore, the compression element 3 is prevented from being displaced when spot-welded; that is, the air gap between the rotor and the stator in the motor can be maintained unchanged at all times.
