Filed: 1987-08-26
Abstract: PURPOSE:To simplify the structure by employing a piezoelectric vibrator with a two-split electrode formed on its upper face and with an entire face electrode formed to its lower face and utilizing a thickness shear vibration as an input/ output transducer thereby eliminating the need for interdigital forming impedance. CONSTITUTION:The piezoelectric vibrator whose upper face is formed with the two-split electrodes 17a, 17b and whose lower face is formed by the entire face electrode 17c utilizing the thickness-shear vibration mode is fitted to one slope of an ultrasonic wave delay medium 1 with the electrode 2 formed thereupon as the input/output transducer. Moreover, a signal voltage application lead wire 9 and a delay signal extraction lead wire 10 are fitted onto the split electrodes 17a, 17b of the transducer. Thus, a signal being the result of mixture of a delay signal voltage and an applied signal voltage is outputted by the piezoelectric vibrator between the electrodes 17b and 17c. Thus, the interdigital characteristic can be formed.

Title: Rhombic oxide superconductor
Inventor: TANAKA SHUNICHIRO
IPC: C01B13/14
Filed: 1988-08-26
Abstract: PURPOSE:To obtain an oxide superconductor having an oxygen-deficient type perovskite structure excellent in superconductive characteristics with good reproducibility by introducing twins in a specific state into crystal grains in phase transition from a tetragonal to a rhombic phase. CONSTITUTION:Twins are introduced into crystal grains so as to intersect at about 90 deg. from >=2 [110] orientations in phase transition of an oxide superconductor having an oxygen-deficient type perovskite structure, e.g., YBa2Cu3O7-delta, to a rhombic phase to provide a rhombic oxide superconductor. Release of strains and sufficient oxygen supply in the phase transition are required to introduce the twins in this state. For example, the introduction can be realized by regulating the density of a calcined compact to about 80-93.5% of the theoretical density in preparing the calcined compact, subjecting the calcined compact to annealing treatment under pressure of oxygen, etc.

Title: Piezoelectric element and polarization thereof
Inventor: TAKAGI SHIGEYUKI
IPC: H01L41/257
Filed: 1989-08-18
Abstract: PURPOSE:To decrease a piezoelectric element in cost and to improve it in strength by a method wherein electrodes, which are formed on both the rear and the front side of a piezoelec tric element formed into a thin plate respectively, are made to deviate much from each other in position when they are viewed in a thicknesswise direction of the piezoelectric element, and the piezoelectric element is polarized by applying a high voltage between the electrodes concerned. CONSTITUTION:The upside and the underside of a ceramic 1 formed into a doughnut-shaped thin plate are divided into many sectoral sections centering on the center P of the doughnut- shaped disc concerned. A small gap 1c is provided between the divided sections respectively, and an electrode 1a is formed on the sections respectively through evaporation. The same as above, many electrodes 1b are formed on the rear side of the ceramic 1. Then, the electrodes 1a and 1b formed on the rear and front of the doughnut-shaped disc piezoelectric element are made to deviate vias from each other in position. That is, an upper electrode (1)and a lower electrode (1) are deviated from each other by three pitches. A high voltage is applied between the upper electrodes 1a and the lower electrodes 1b kept as deviated from each other. By this setup, polarization takes place between the electrodes (1) in a direc tion slightly inclined to the plane of the thin disc in the piezoelectric element. This polarizing process is successively carried out between electrodes (2) and (2) and between electrodes (3)and (3).

Title: Float valve for absorption refrigerator
Inventor: KANEKO TOSHIYUKI
IPC: F25B15/00
Filed: 1987-08-26
Abstract: PURPOSE: To improve a durability of a float valve by a method wherein absorbing liquid is fed in such a way that a gaseous phase part is left in a hollow space of a float of a float valve of an absorbing type freezer having the hollow float arranged at an absorbing liquid surface in a high temperature generator. CONSTITUTION: In the float valve of an absorbing freezer, a temperature and a saturation vapor pressure of absorbing liquid in a hollow space of its float F are similarly changed in correspondence with a variation of temperature of the absorbing liquid and a saturation vapor pressure in a solution box B at an outer circumference of the float F so as to keep a pressure difference between an indoor area and an outdoor area at a substantial zero state. Under this action, even if the temperature or the vapor pressure of the absorbing liquid within the high temperature generator are frequently changed, an excessive repetitive load is scarcely applied to an outer shell of the hollow float F and a probability of occurrence of cracks at the outer shell of the hollow float F can be reduced. Accordingly, it is possible to improve a durability of the float valve of the absorbing freezer.

Title: Metallic spectacle frame
Inventor: TSUCHIDA TSUTOMU
IPC: G02C5/14
Filed: 1995-07-29
Abstract: PROBLEM TO BE SOLVED: To prevent a user from being under a nickel allergy by wearing of spectacles by forming resin layers in the regions on the inner flanks of temples which come into contact with the skin when the spectacles are worn. SOLUTION: The sections of the temples 4 have a longitudinally long rectangular shape and are formed with the resin layers 8 on their inner flanks 7. Namely, not only the rims and connecting members of a spectacle frame but the surfaces of the temples 4 as well are subjected to prescribed color plating and the resin layers 8 are formed on the surface of such plating layers by applying resins thereon. The resins are not restricted at all, insofar as the inner flanks 7 of the temples are coatable with these resins. A good contact with the skin is obtd. if a silicone resin is used as the resin is substantially soft. In addition, the silicone resin makes the temples 4 hardly slippable when the temples are pressed to the skin. The worn spectacles are thus stabilized without mispositioning. Round surfaces of a suitable size are formed on the upper and lower angle parts 9, 9 of the resin layers 8 applied on the inner flanks 7 and the smooth resin surfaces eventually come into contact with the skin.
