Title: Metal weight for sea farming
Inventor: SUDO MASAKI
IPC: A01K61/00
Filed: 1997-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a metal weight for sea farming capable of surely inhibiting undersea marine culturing equipment from floating and maintaining stability, free from giving an adverse effect on the farmed fish, etc., and environment- friendly. SOLUTION: A disk shaped metal lump 2, equipped with a pair of through holes 3, 4 and one of the through holes 3 is used to bundle a string to attach the metal lump 2 to the undersea marine culturing equipment. The other through hole 4 is constituted so that seawater is able to come and go inside the metal lump 2 as a means decreasing the resistance of the metal lump 2 to the flow of seawater. The metal weight 2 is entirely contact free from seawater by setting a coating layer of a synthetic resin on the all surface (two sides and outer periphery of the metal weight 2 and inner walls of the through holes 3, 4).

Abstract: PURPOSE:To make it possible to eliminate the need for a fine processing technology and prepare a high performance device which uses an oxide superconductor by controlling a superconducting current flowing in a superconduction circuit with gate voltage. CONSTITUTION:At first, when compared with an oxide insulator, a thin film of an insulator with a smaller amount of oxygen is formed.

The current which flows in the superconducting channel 10 between the electrodes 2 and 3 is controlled with voltage applied to the electrode 4. The channel 10 is turned on and off with the voltage applied to the electrode 4, which calls for the superconducting channel 10 with an extremely thin film. Oxygen ions are implanted into a part which becomes a superconducting region where a thin film has been formed.

Abstract: PROBLEM TO BE SOLVED: To obtain a picture display device suitable for the characteristic of the visual angle of a human being by making the pixel density of a display screen in a horizontal direction denser than the picture element density thereof in a vertical direction. SOLUTION: The pixel density of the display screen 10 in the horizontal direction is made denser than the pixel density thereof in the vertical direction.

Besides, a pixel 5 is shaped so that the width (a) thereof in the horizontal direction is 1/3 of the width (b) in the vertical direction [the width (b) in the vertical direction becomes three times of the width (a) in the horizontal direction].  Then, picture data displayed on the screen 10 as a visible picture is the picture data obtained by executing the conversion processing of the pixel density so that original picture data is made suitable for the density and the shape of the pixel or the picture data read according to the density and the shape of the pixel. Thus, the picture display device is constituted so that a display action suitable for the characteristic of the visual angle can be executed.

Title: Multilayer circuit board
Inventor: TAKEUCHI MEGUMI
IPC: H05K3/46
Filed: 1990-09-27
Abstract: PURPOSE:To prevent the disconnection of a conductive pattern by forming a bent section to a multilayer circuit board and, at the same time, making the film thickness of the conductive pattern formed at the bent section thicker than that of the conductive pattern formed in the other section. CONSTITUTION:A conductive pattern is formed on a film' substrate by screen printing so that the thickness of the conductive pattern 23 formed at a bent section 22 can become thicker than that of the conductive pattern 21 formed in a flat plate section 20 by about 10mum and the thickness of the pattern 23 is set at about 30 7mum. This multilayer circuit board M is formed by bending a laminated body of several pieces of such film substrate to an, for example, angular form after the laminated body is formed by sticking the substrates to each other by thermocompression bonding. Since the thickness of the conductive pattern 23 at the bent section 22 is thicker than that of the conductive pattern 21 in the flat plate section 20, no crack nor disconnection occurs in the pattern 23 even when the pattern 23 receives strong bending stress.

Title: Manufacture of piezoelectric body and ferroelectric thin film element
Inventor: MIYASHITA SATORU
IPC: H01L41/39
Filed: 1992-09-28
Abstract: PURPOSE:To obtain a piezoelectric element having a high piezoelectric strain constant and high Young's modulus by applying a sol prepared by hydrolysing a raw material to a porous gel thin film after forming the thin film by adding and homogeneously mixing a soluble organic high polymer to and in the sol prepared by hydrolyzing the raw material and calcining the applied sol. CONSTITUTION:After forming a platinum electrode on a silicon substrate, a porous gel thin film 11 having a film thickness of 2.5mum is formed on the surface of the electrode without cracking the thin film 11 by applying a sol which is prepared by hydrolysing a raw material and adjusted in composition by adding an organic high polymer to the electrode by spin coating and heating the applied sol to 350 deg.C. As a result, numerous narrow pores of about 0.02mum in diameter are formed in the thin film 11. Then the same sol prepared by hydrolyzing the raw material is applied to the surface of the thin film 11 by spin coating without adding the organic high polymer and the sol is heated to 400 deg.C. Therefore, a piezoelectric element which can be easily increased in thickness and has a high piezoelectric strain constant and high young's modulus can be obtained at a high yield.

IPC: H05K1/16
Filed: 1993-10-15
Abstract: PURPOSE:To attenuate in trap the spurious frequency by connecting in series the self-resonance frequency control inductors provided on a printed board to the laminated chip capacitors. CONSTITUTION:The dielectric resonators R1-R2 are connected to each other via the coupling inductors L1 and L2 and the capacitors C. The filter of the TX side includes a 1st pi-type LPF consisting of the laminated chip capacitors C1 and C2 and the inductor L1, and a 2nd pi-type LPF consisting of the lamination chip capacitors C2 and C3 and the inductor L2.

Title: Ultrasonic probe
Inventor: SATO IZUMI
IPC: G01N29/04
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To improve the flaw detecting accuracy, reproducibility, etc., of an ultrasonic probe by eliminating the fluctuation of the flaw detecting sensitivity of the probe caused by the thickness change of a water film. SOLUTION: Ultrasonic pulses generated by the vibrator 24 of an ultrasonic probe 20 enter a water film 40 through the recessed and projecting section 23a of a delaying material 23. Part of transmitted waves a1 and a2 are reflected by the surface of a material 41 to be inspected and reflected waves b1 and b2 return to the projecting section A and recessed section B of the recessed and projecting section 23a of the probe 20.  The reflection at the route of the recessed section B becomes a 1/2-wavelength in the round trip, because the depth of the groove is 1/4-wavelength, and, since the reflected waves b1 from the projecting section A and those b2 from the recessed section B are inverted in phase by 1/2 wavelength (180 deg.) and offset each other, the same state as that obtained when the pulses are not reflected by the recessed and projecting section 23a on the surface of the probe 20 is obtained and no interference occurs at the wave height level. Therefore, the flaw detecting sensitivity of the probe does not fluctuate even when the thickness of the water film 40 changes with the movement of the material 41 or probe 20.
