摘要： PROBLEM TO BE SOLVED: To easily handle a small-sized transparent plate and enable high- precision positioning by providing a recessed part which has a depth less than the thickness of a transparent plate and contains the transparent plate at the center part of a plate type component and a through hole at a part of the recessed part. SOLUTION: The recessed part which has a depth less than the thickness of the glass plate 1 and contains the glass plate 1 is formed on the reverse surface of the center part of the fixing jig 6 and the through hole 8 which penetrates the fixing jig 6 is provided at a part of the recessed part. The fixing jig 6 and glass plate 1 which are held by vacuum suction pads 10-1 to 10-3 are moved and the glass plate part is positioned above optical fibers 3 arrayed in grooves on a substrate 2, and the glass plate 1 is pressed against the optical fibers 3. Then, the vacuum suction pads 10 are released the retract them, and an ultraviolet-ray-setting adhesive is injected between the glass plate 1 and substrate 2 and set by irradiation with ultraviolet rays through the through hole 8. After the adhesive is set, only the fixing jig 6 is sucked and collected. Consequently, the optical fibers 3 can be fixed between the substrate 2 and glass plate 1.

摘要： PROBLEM TO BE SOLVED: To precisely grip a micro thin piece part. SOLUTION: When two gripping members in jigs 2a are closed together, a micro optical filter 1 can be gripped. An oscillators 3 installed in the jig 2a is vibrated at a vibration frequency of 2kHz and a vibration amplitude of 3μm, for example. Although the filter 1 is apt to stop on the tilting part in the jig 2a because of charge in the filter 1 or friction between the filter 1 and the jig 2a, the filter 1 is dropped to the lower end of the jig 2a, for the jig 2a is oscillated by means of the oscillator 3. In this way, the position and the posture of the filter 1 to the jig 2a can be precisely decided, so that the filter 1 can be gripped in a desired position.

摘要： PURPOSE:To provide an optical fiber with a rod lens which is producible at a low cost by using a multimode optical fiber which is cut into a prescribed length to provide the fiber with a light condensing function as a rod lens without impairment of the ease of an assembling operation and using a capillary which is a generally marketed product without using a ferrule of special specifications. CONSTITUTION:This optical fiber with the rod lens consists of the single mode optical fiber 1, the rod lens 2 formed by cutting the multimode optical fiber 2' into a prescribed length to provide the fiber with the light condensing function and the capillary 3. The rod lens 2 is brought into contact with the front end of the single mode optical fiber 1 and is inserted and fixed in this state into the hole of the capillary 3 to make the rod lens into an integral structure with the single mode optical fiber 1.

摘要： PURPOSE:To enhance measuring accuracy in a simple constitution by measuring in advance a relation between the position of each stage, and each image at the aforesaid positions, or each error in posture for a measured object, and thereby removing errors made at the time of measurement based on the aforesaid relation. CONSTITUTION:Each coordinate of three marks MA through MC in the Z direction out of marks for the four corners of a two dimensional measuring reference scale 4, is obtained with X and Y axis stages 8 and 6 driven, based on the obtained coordinates, a parallel adjustment for the X Y scanning surface of the scale 4 and a photographing optical system is carried out, and the adjustment of a rotating angle around a Z axis for a Z axis (a Y axis) is also carried out, so that the relative error in posture between the stages 6 and 8 is thereby corrected. Next, the positional coordinate of each mark in the X direction from the mark MA is measured the difference between each aforesaid measured coordinate and the coordinate of each mark which is accurately measured in advance, is stored as measuring errors which depend on the posture of each stage 6 and 8 at the positions of the respective marks. In a practical measurement, a corrected value where each corresponding measuring error is added to each measured value at the measuring positions of the stages 6 and measured value where each measuring error due to the posture of each stage 6 and 8 is removed.

摘要： PURPOSE:To enable automatic detection of etching end by providing a light source above a substrate holding cassette and a light sensor below there. CONSTITUTION:An Si substrate 2 which is provided with a nitride film 1 in a part excepting a position on a surface to be etched is held inside a quartz substrate holding cassette 4 by a chemical resistant O-ring 3. The substrate holding cassette 4 is immersed in KOH liquid 5; then, a large quantity of bubble 7 of hydrogen gas is produced from an etching surface 6 and scattering is caused by a large quantity of bubble 7 even if the Si substrate 2 is irradiated by an irradiation lamp 8. Therefore, light does not attain a solar battery 9 which is arranged below the etching surface 6. However, if etching is proceeded and the etching surface 6 is transferred from an Si surface to the nitride film 1, etching is stopped and bubble 7 is not produced. As a result, light 10 transmitted through the nitride film 1 and the substrate holding cassette 4 attains the solar battery 9 and etching end can be judged by detecting a voltage thereof.
