Abstract: PROBLEM TO BE SOLVED: To realize a cold neutron lens based on refraction optics. SOLUTION: A cold neutron refraction lens system is constituted of an array of thin lenses. In a lens holder 18, 5 concave lens elements 11 are placed. The number of the lens elements 11 depends on the neutron focal distance of each element 11. Total focal distance is f=f0 /n, where n is the number of elements in the array and f0 is the focal distance of a single lens. The lens material has a small negative relative refraction factor n-n0 , where n0 is refraction factor (=1). Therefore, focusing element should be concave lenses and not convex lenses normally used in focusing wavelength of light. A preferable material have cold neutron absorption (determined as absorption of neutron of 10 angstrom) at 10 barn or less and restricted interference scattering cross sectional area for neutron of 2200 m/sec to be 3 fm or more.

Abstract: PROBLEM TO BE SOLVED: To produce an element having an electric contact formed from an alloy having improved wear resistance. SOLUTION: The alloy is particularly useful for a microrelay formed by an MEMS technique. In one executing mode, sufficient precipitation hardening improves its wear resistance, but, the alloy is selected so as to maintain the electrical conductivity to the level lower than that in which the precipitation is reduced to a degree which is not allowable. As the alloy, at least one among rhodium, platinum, palladium, gold and ruthenium is contained. This is attained by an alloying material which has extremely limited solid solution properties in noble metal lattices, e.g. a solid solution degree lower than 4 wt.% or does not have solid solution properties. In a second executing mode, the alloy contains noble metal lattices 50 and dispersive particles 52 insoluble in the lattices, and these dispersive particles provide similar strengthening mechanisms.

Abstract: PROBLEM TO BE SOLVED: To provide an optical fiber communication system consisting of an optical strain switching element. SOLUTION: The article consists of the switching element which guides signal radiation of wavelength λ from a signal radiation input port 111 to a specific radiation output port 112 in response to a light control signal 18 applied to an optical strain member 12, which is so arranged that variation in the size of a member shifts the relative position between an optical fiber, e.g. 111 and another element to guide the signal radiation to a specific signal radiation output port, e.g. 112.

Abstract: PROBLEM TO BE SOLVED: To provide a package technology for sealing an MEMS device hermetically so that the MEMS device can be built in a CMOS circuit. SOLUTION: The inventive package technology can be employed for packaging an MEMS device according to a conventional CMOS package technology. The invention also provides means for controlling the operational environment of the MEMS device. In the inventive package, a protected cavity is provided around an MEMS device fabricated by a flip-chip bonding process. According to one embodiment, a firewall is formed on a first substrate around the MEMS device which is sealed in a cavity bounded by the firewall. Subsequently, another substrate is flip-chip bonded to the first substrate holding the MEMS device.

Abstract: PROBLEM TO BE SOLVED: To provide a multi-port variable capacitor based on an MEMS(micro electromechanical system). SOLUTION: A circuit element is provided with a movable plate 308 supported on first and second coplanar fixed electrodes. A bias power source 324 is electrically connected to the first fixed electrode 316 and the plate 308, and applies a bias voltage V1 across the electrode 316 and plate 308. An AC signal carrying line is electrically connected to the fixed second electrode 322 and plate 308. When the bias voltage V1 is applied, an electrostatic attracting force acts between the first electrode 316 and plate 308. Consequently, the plate 308 moves downward toward the electrode 316 and the distance between the plate 308 and electrode 316 is reduced. Accordingly, the capacitance of a multi-port variable capacitor 302 increases. In this capacitor 302, the bias voltages and signals are electrically separated (isolated) from each other.
