摘要： PROBLEM TO BE SOLVED: To provide a miniaturized mechanical type optical switch which can be produced through the simple assembly process of piling components on a substrate and reduces the transmission loss of light. SOLUTION: Concerning the optical switch for switching an optical path by relatively moving movable optical fibers 20a and 20b held by a movable optical fiber holding member 30 and fixed optical fibers 21a, 21b, 21c and 21d fixed by a fixed optical fiber fixing member 32 through an electro-magnetic actuator, the movable optical fiber holding member 30 and the fixed optical fiber fixing member 32 are prepared from soft magnetic ceramics. Thus, since the electro-magnetic actuator and the member for fixing the optical fibers can be shared, the optical switch can be miniaturized. Further, the miniaturized mechanical type optical switch can be provided through the simple process of piling components on the substrate.

摘要： PROBLEM TO BE SOLVED: To control a head slider to jump on the disk surface by arranging a load arm having a projection on the surface in the opposite side of the head slider mounting surface and a gimbal for mounting the head slider. SOLUTION: A suspension loading a head slider receives an impact load to be deviated in the direction to become far from a disk and a head slider 20 receives a force in the direction as isolated from the disk surface. In this case, a projection formed on the load arm 20 of suspension is placed in contact with the suspension and thereby further displacement of the load arm 20 can be controlled and the head slider will never be floated.

摘要： PURPOSE: To provide an optical waveguide switch which is stable for a long time with high reliability by solving the problem of evaporation and deterioration on fluid for switching an optical path. CONSTITUTION: A rotatable prism 2 which has a groove 3 perpendicular to a planar surface formed by a core for a signal on an upper part is disposed on the crossing part of the cores 100 and 101 for an input signal and the cores 110 and 111 for an output signal which cross each other, and an ultrasonic vibration generator provided with electrodes 801 and 802, a piezoelectric body 6 and an elastic body 5 is disposed under the prism 2. Thus, since the injection and the discharge of the fluid are not required in the case of switching the optical path, the operation of the optical waveguide switch is stable for a long time.

摘要： PURPOSE:To enable joining of a large area by using roll pressurizing as a means to pressurize a member to be joined and thereby eliminating influence from the waviness of a joining surface. CONSTITUTION:In a joining method in which, after a contaminated layer is removed from the surfaces to be joined, a member to be joined is pressurized by a pressurizing means, and the surfaces to be joined are adhered closely with each other and joined. Pressurizing by means of a roll 11 is employed as a means to pressurize the members 14a, 14b to be joined and an insert material 15. Then, while a roll 11 is rotated on the members 14a, 14b and the insert material 15, the roll is relatively moved with them by using a stage 12, and both surfaces to be joined are thereby adhered closely with each other and joined.

摘要： PURPOSE:To obtain the ultrasonic probe which has superior flaw detection sensitivity and detection accuracy with respect to a defect by computing conditions under which all ultrasonic waves from ultrasonic probes are converged on a focus position (object position of flaw detection) set in a sample. CONSTITUTION:An ultrasonic probe consists of an ultrasonic wave vibration source and an acoustic lens 1 and performs ultrasonic flaw detection with respect to the sample 2. Then the acoustic lens 1 has a curved lens surface 1a set according to a function expression containing constants, i.e. ultrasonic wave propagation acoustic velocities CL, CW, and CD of the acoustic lens 1 as a medium for ultrasonic waves, a single medium where the sample 2 is present, and the sample 2, the distance W between the acoustic lens surface 1a on the lens axis and the surface 2a of the sample, and the distance D between the surface 2a of the sample on the lens axis and the object position F of flaw detection in the sample 2 where ultrasonic waves are focused. Then the acoustic lens surface 1a which satisfies the conditions is used to obtain the ultrasonic probe equipped with the acoustic lens 1 which focus the ultrasonic waves on one point in the sample 2.

摘要： PURPOSE:To enable metallic wire to be bonded to a metallic electrode without loading a high pressure, by applying ion beams or the like to the surfaces of the wire and the metallic electrode for cleaning them, and overlaying one on the other without recontamination. CONSTITUTION:Metallic wire 7, a semiconductor chip 1 and a substrate 2 are disposed in a vacuum vessel. The vacuum vessel is then evacuated. Subsequently, single or mixed gas having a high purity is introduced to a plurality of ion or atom guns 3, 4 previously disposed in the vacuum vessel, and ion or atom beams thereby produced are applied to the tip end of the metallic wire 7 and to electrodes on the chip 1 or on the substrate 2 for a predetermined period of time. The part of the wire 7 irradiated with the beams is overlaid on and bonded to the electrode. Wire bonding operation suitable for high-density packaging can be realized in this manner.

摘要： PURPOSE:To economically perform the solid phase joining of a large area by removing contaminated layers of the joining surfaces and the surface of In-Sn alloy foil containing the specific quantity of Sn in vacuum and superposing the joining surfaces mutually via the In-Sn alloy foil. CONSTITUTION:Materials 1 and 2 (copper, etc.) to be joined and insert material (the In-Sn alloy foil) 3 are set up in a joining chamber 4. The insert material 3 is composed of the In-Sn alloy foil containing 25-75wt.% Sn. The inside of the joining chamber 4 is evacuated in a vacuum (about 10 Torr) state and Ar gas, etc., with high purity are flowed in atom sources 5 and 6 and projected on the surface of the insert material 3 set up on the joining surface of an upper material 1 to be joined and a lower material 2 to be joined. At this time, the contaminated layers on the surfaces are removed. Next, the upper material 1 to be joined is descended and subjected to solid-phase joining to the insert material 3. The upper material 1 to be joined is raised and the upper and lower materials 1 and 2 to be joined are subjected to solid-phase joining to each other via the insert material 3 by operating in the same way. In this way, the solid phase joining of the large area can be economically performed.
