Abstract: PURPOSE:To hold a hold lip by a support protrusion when a welt is removed from a mating engaging member and to suppress dislocation of the welt by a method wherein a support protrusion adjoining a hold lip is formed on the opening side on the inner peripheral side of a welt body. CONSTITUTION:A welt body 2 in a U-shape in cross section of a welt 1 has a core 3 embedded therein, and a plurality of hold lips 4 by which a mating engaging member 5 is held between the nip formed are protruded from the inner peripheral side. A notch 6 is formed in the base part, on the opening part side of the welt body 2, of the hold lip 4.

Title: Production of thin film by hydrothermal synthesis method
Inventor: KANBE YUMI
IPC: H01L41/39
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a process for industrially producing homogeneous films with good reproducibility inexpensively in a method for forming the thin films of a multi component oxide by a hydrothermal synthesis method on a substrate. SOLUTION: This hydrothermal synthesis method forms the thin film of the multi component oxide on the substrate by holding the substrate in an aq. soln. dissolved with plural metal salts under pressurization conditions and heating the substrate while applying vibration of >=1Hz perpendicularly on the substrate. The thin film is hydrothermally synthesized in one stage by using the multi component oxide forming raw material consisting of the remaining combination exclusive the compd. reacting with the metal elements on the surface of the substrate. The thin film is hydrothermally synthesized in two stages by using all of the raw material compds. after the crystal nuclei of the multi component oxide are precipitated in the first stage.  As a result, the multi component oxide thin film exhibiting a piezoelectric characteristic is produced to a large area at a uniform thickness even if the substrate is not subjected to a polarization treatment. Since a high-temp. treatment, such as baking, is not required, the use of an org. material for the substrate is possible as well. This process is, therefore, applicable to the production of piezoelectric elements, such as piezoelectric monomorph and piezoelectric bimorph and various composite materials, such as laminated actuators and laminate capacitors.

The pulling up speed and input quantity of heat are optionally changed on the basis of the calculation. On the other hand, the single crystal ingot 1 after completing the pulling up and growing is placed on a measuring base plate 4 of a diameter measuring instrument 3 to actually measure the diameter of specific plural parts in the longitudinal direction. The resultant values are compared with an estimated value of diameter and errors are calculated to provide the correction value for the diameter control, which is used to calculates the estimated value (fl) of diameter in the course of the next growing of a single crystal. The aimed single crystal is grown while controlling the diameter.

Title: Rigid thin plate separating apparatus
Inventor: IZUMI AKIO
IPC: B65H3/62
Filed: 1984-04-19
Abstract: PURPOSE:To permit the easy and continuous separation of thin plates and permit the incorporaion of the thin plate into automation line by vibrating the thin plate positioned on the holding side among the accumulated rigid thin plates and scattering the moisture and dissolved substance between layers by the vibration energy which is generated by the undulated strain due to resonance. CONSTITUTION:When a vibrator element 1 is vibrated, the vertical movement on the edge surface 1F is transmitted to a glass thin plate 2A in contact state, and said thin plate 2A is distorted into undulated state in the cycle determined by the frequency of the vibration and the propagation speed in 2A. Though the vibration is transmitted through the part in close contact with a thin plate 2B in the upper layer of the thin plate 2A, the moisture as the medium for close contact is vaporized by the vacant phenomenon generated by the vibration, and the close adhesion force is dissipated, and the thin plate 2B is kept in the floated state from the thin plate 2A. Therefore, when the edge surface 1F of the vibrator element 1 is installed in tilt state or the thin plate layer 2 is held in the previously tilted state, the thin plate 2B at the upper-layer position slides in the direction of tilt, and the thin plate 2A and the thin plate 2B can be perfectly separated.
