Abstract: A handicraft clip is provided for forming a pleat in a cloth. The clip includes a relatively wide base plate and a narrower fastening plate connected to the base plate via a connecting hinge portion having a reduced thickness for allowing pivotal movement of the fastening plate relative to the base plate. The base plate is formed with a generally elliptical through-hole, while the fastening plate is provided with a locking protrusion to be fitted into the through-hole of the base plate when the base plate and the fastening plate are superposed on each other. The fastening plate includes a cloth holding portion of a generally constant width. The cloth holding portion is formed with a slit for insertion of a cloth. The slit extends from the distal end of the cloth holding portion toward the locking protrusion.

Abstract: A handicraft assisting tool is used for stitching a fabric having a first face and second face into a pouch. This handicraft assisting tool has a first plate and a second plate that collaborates with the first plate. The first plate has a plurality of rhombic unit pieces of the same size arranged in a row, and an inner face abutting on the first face of the fabric. The second plate has a plurality of rhombic unit pieces of the same size arranged in a row, and an inner face abutting on the second face of the fabric. Each of the unit pieces of the first and second plates is of the same size. The first plate and the second plate are each provided with folding operation instructions for folding these plates along a diagonal line of each unit piece and a borderline between adjacent unit pieces.

Abstract: A tool is provided for facilitating the making of a decorative knot. The knot-making tool includes a generally flat main body, and several string engagement cutouts formed on the periphery of the main body. The string is brought into engagement with these cutouts in the prescribed order specified by the indication marks put on the main body.

Abstract: A bonded wafer comprising a filmy bond wafer, a base wafer, and an intermediate silicon dioxide layer, wherein the periphery of the bond wafer is etched; this bonded wafer is made by: subjecting the bond wafer to an oxidation treatment to form an oxide film over it; joining the two wafers in a manner such that the oxide film-covered face of the bond wafer is put on the base wafer to thereby sandwich the oxide film between the wafers; heating the combined wafers to thereby create a bonding strength between the two wafers; grinding the exposed face of the bond; etching the periphery of the bond wafer to remove the portion which is not in contact with the base wafer; and polishing the exposed face of the bond wafer until it becomes a thin film.

Abstract: A scanning tunneling microscope has an STM unit including a probe for scanning the surface of an object. The STM unit has at its outer peripheral surface a cylindrical enclosing member extending towards an object table. When the object is observed, the object table is elevated or the STM unit is lowered, so that the enclosing member is urged upon the table. The table and the STM unit constitute one body. As a result, relative movement between the object and the probe can be prevented, and also influence due to vibration can be prevented. In addition, the enclosing member isolates the object and the probe from the outside space, whereby electric noise, magnetic noise, sound noise and air flow are shielded. Thus, the influence due to external vibration can be reduced, and the stability is enhanced.

Abstract: An additive contains a deactivation agent functioning at soldering temperature. This novel additive is used for fluxes and soldering pastes. In the course of soldering, the deactivation agent in the additive deactivates an activator such as organic acids contained in the flux and the soldering paste in order for removal of an oxide film from a metallic base used for electric circuit. By use of the additive, corrosion of the metallic base with the activator is prevented even though the activator remains on the base. The additive enables one to omit an unnecessary washing step from a preparation of electric circuit.

Abstract: A scanning tunneling microscope includes a piezoelectric driver expanding and contracting according to a voltage applied thereto to adjust the distance between a sample and a probe. A servo circuit outputs a servo voltage to control the expansion and contraction of the piezoelectric driver to keep a tunnel current flowing between the sample and the probe at a constant value. A correction voltage generating circuit generates a given correction voltage to correct a voltage to be applied to the piezoelectric driver. An adding circuit adds the servo voltage and the correction voltage together and supplies an added output to the piezoelectric driver. A control circuit controls the correction voltage according to the servo voltage to set the added output to a given reference voltage.
