Patent JP-S6313370-A (JP)
Title: Solid-state image sensor
Inventor: TABEI MASATOSHI
IPC: H04N5/335
Filed: 1986-07-04
Abstract: PURPOSE:To improve the sensitivity of a FT system solid-state image sensor by forming one or more of opening holes to polysilicon on a vertical transfer line and setting silicon potential just under the opening holes at a value higher than the maximum value of the potential of the transfer line at all times. CONSTITUTION:A transfer electrode 5 to which opening holes 7 are shaped is formed onto a p-type silicon substrate 8 through a gate oxide film 9 in a sensor. Potential just under the opening hole 7 is set so as to be made higher than the maximum potential of a transfer line fluctuating by a clock input at all times. Consequently, signal charges converted in a photoelectric manner in an opening hole 7 region are not stored just under the opening hole, and fall to the transfer line side at a low potential level. When the clock input is set at an L level on transfer, the potential of the transfer line rises, and stored signal charges are all transferred to an adjacent electrode in the vertical direction. Accordingly, effective optically formed carriers are generated, thus improving sensitivity.

Title: Nondirectional underwater ultrasonic transducer
Inventor: INOUE TAKESHI
IPC: H04R17/10
Filed: 1986-07-02
Abstract: PURPOSE:To attain an acoustic radiation characteristic highly efficient for a wide frequency band and a high-power transmission by constituting the titled transducer with cylindrical ceramic piezoelectric oscillators and a non- piezoelectric cylinder fitted firmly with the outer surface of the former cylinder. CONSTITUTION:The cylindrical ceramic piezoelectric oscillators 11 and 11', and the non-piezoelectric cylinder 12 fitted firmly with the outer surface of the former, constitute the titled transducer. For the non-piezoelectric cylinder, a material whose rigidity can be made high in the direction of center axis is desirable which may be, for example, a carbon-fiber reinforced plastic(C-FRP) or glass-fiber reinforced plastic(G-FRP) in the direction of whose fibers coincides with that of the center axis, fiber reinforced metal(FRM), Mg alloy, or Al alloy. As a result, since the effective mass per unit radiation area comes considerablly smaller, the acoustic impedance matching with water is drastically improved. And thus a transducer which is effecient for a wide frequency band can be obtained.

Title: Through-type capacitor
Inventor: KUROKUZUHARA MAMORU
IPC: H01G4/35
Filed: 1987-06-26
Abstract: PURPOSE:To prevent a destruction phenomenon of a dielectric from being caused by a method wherein a central conductor having an uneven part on an external circumference face is brought into contact with an inner wall face of a through hole with a circular cross-section of the dielectric at an end part of a protruding part. CONSTITUTION:At a ceramic dielectric 1 an inner wall face of a through hole and an outer circumference face are metallized by a nickel-plating method or the like; a capacitor which uses the inner wall face and the outer circumference face as electrodes is formed. A central conductor 2 to be used as one electrode is inserted into the through hole of the dielectric 1, and is connected to the inner wall face of the hole by a soldering operation; a grounding electrode sheet 3 acting as the other electrode is soldered to the outer circumference face. External housings 4, 5 are attached to the grounding electrode sheet 3, and are fixed by injecting an insulating resin 6. End parts of narrow protruding parts at the central conductor 2 are connected to the inner wall face of the through hole at the dielectric 1 by using a solder 7. Because a width of each connection part is narrow, the solder protrudes due to a plastic deformation in a circumferential direction of the through hole at the dielectric; accordingly, a difference in thermal expansion between the central conductor 2 and the dielectric 1 can be absorbed. Because a space for an elastic deformation of the central conductor 2 is produced, the dielectric 1 is not damaged.
