Title: Optical element with ridge type optical waveguide
Inventor: KATSUYAMA TOSHIO
IPC: G02B6/30
Filed: 1999-07-28
Abstract: PROBLEM TO BE SOLVED: To improve the optical coupling efficiency irrespective of the form of optical elements and optical waveguides to be directly coupled to a ridge type optical waveguide by forming the ridge in at least one of the input or output part of the ridge-type waveguide to transfer polaritons as tapered to gradually decrease its width to the end so that the width of the ridge becomes smaller than the cut off width. SOLUTION: In the cross section of the ridge type optical waveguide,the waveguide has a core 1 in the center and has clads 2, 3 over and under the core, respectively, to form a ridge by the upper part of the core 1 and the clad 2. In this ridge type optical waveguide, the width of the ridge is decreased toward the input or output part for light. In particular, the width is gradually decreased so that the width of the ridge becomes smaller than the cutoff width. By gradually decreasing the width of the ridge to the end, the mode profile is increased and, as a result, the coupling efficiency with an optical fiber can be significantly improved.

Filed: 1992-07-20
Abstract: PURPOSE:To obtain clad foils wherein the film thickness of each foil is uniform and the film thickness of each foil is thick by using a rolled aluminum-copper clad foil in which an alloy layer composed of aluminum and copper is not formed. CONSTITUTION:When an alloy layer composed of aluminum and copper is interposed at the interface of aluminum and copper, a rolled aluminum-copper clad foil 5 lowers an etching property when a circuit wiring pattern is formed.

Title: Manufacture of mask for x-ray exposure
Inventor: TSUMORI TOSHIRO
IPC: G03F1/22
Filed: 1989-08-19
Abstract: PURPOSE:To eliminate deformation of a mask pattern by a method wherein an absorber foil whose internal stress is small is bonded to a support film and the absorber foil is patterned. CONSTITUTION:Gold is rolled to form an absorber foil 3 whose thickness is about 1 to several mum. This foil is annealed as required to make its internal stress zero. A transmission body 2 composed of a silicon nitride such as Si3N4 is formed on a silicon wafer 1 by, e.g. a low-pressure CVD operation; the absorber foil 3 is bonded to its surface by using a heat-resistant adhesive, e.g. a polyimide 4. Then, the surface of the absorber foil 3 is polished to reduce the foil down to a required film thickness. After that, the absorber foil 3 is patterned by an EB or ion beam exposure method. Consequently, even when an absorber is patterned, a compressive stress and a tensile stress are not caused; there is no danger that a positional deformation and a deformation outside a face are caused in a mask pattern composed of the absorber.

Abstract: PROBLEM TO BE SOLVED: To reduce distortion by distortion compensation near an output saturation point, to raise the operation point of a high output amplifier and to perform efficient signal amplification by using at least one of a base frequency component and a double frequency component among the even-number power product of plural radio signals to be amplified and amplitude-modulating the original plural radio signals. SOLUTION: An amplitude modulation means 31 for turning the base frequency component or the double frequency component or both of the even- number power product of an input signal component and carrier wave signals to modulation signals for the input signal component functions as this distortion compensation circuit. Then, the distortion of the high output amplifier 30 to be compensated of a post stage is reduced. That is, a nonlinear distortion component is generated in the same frequency band as an original radio signal component in the amplitude modulation means 31, complete separation is performed in the frequency band different from the original radio signal component and a distortion component is adjusted.  Thus, since adjustment is facilitated even near the output saturation point where the adjustment is difficult, the distortion reduction near the output saturation point is obtained.
