Abstract: PURPOSE: To obtain a condenser element having high quality while holding the grain size distribution of raw material powder by prohibiting the bridging of the raw material powder by using air, thereby minimizing the amt. of the raw material powder to be supplied at the time of supplying the raw material powder to a plunger part. CONSTITUTION: The raw material tantalum powder housed in a tank 5 falls by gravity from a passage 6 and is fed by the air into a rotary drum 9 via an air passage part 8 made of a perforated metal. The raw material powder fed into the rotary drum 9 is accumulated in recesses 10 of the rotary drum 9 and rotates together with the drum 9. The raw material powder is sent to an inclined chute 13 consisting of a gliding surface 11 of a perforated plate provided with an air feed port 12 and is accumulated in a proper floating state onto the perforated plate 23 enclosed by a frame of a measure 25. The raw material powder is held in a stably deposited state by the air slightly flowing out of the air feed port 24 and moves together with the movement of the measure 25 having a partition arm 26. The moving raw material powder arrives at the top of the plunger part 27 and falls therein.  As a result, the homogeneous condenser elements having the high quality are efficiently obtd. without cyclically using the raw material powder, unlike heretofore.

Title: Force accumulating device for circuit breaker
Inventor: AMITA YOSHIAKI
IPC: H01H5/04
Filed: 1993-10-26
Abstract: PURPOSE:To accumulate the force of a spring within a short time and contribute to the improvement in reliability of a transmission system by transmitting the rotating force of a power source by automatically selecting a gear pair according to the magnitude of the load of a shaft. CONSTITUTION:When a load is increased to a fixed torque or more, a torque limit switch 13 is operated to break the relation between a shaft 8 and a shaft 10, and the driving force is transmitted by a second transmitting route.

Title: Method and apparatus for changing sharpness
Inventor: RAINERU ETSUSHIYUBATSUHA
IPC: G06T5/20
Filed: 1994-10-31
Abstract: PURPOSE: To obtain a method and a device for changing sharpness of a copy of an electronically encoded natural scene image. CONSTITUTION: Since the tone reproduction curve(TRC) correction is optionally performed to an image at an initial stage, a high frequency factor of the image is totally corrected for contrast and/or exposure before the sharpness is corrected at a TRC correction device 200. Then, a local sharpness Δ is evaluated from the image by a sharpness evaluating device 204. Sharpness evaluation Δis optionally changed by using plural numbers of sharpness evaluation by a modifier 206 so that a Δmod is obtained. One possible change is to calculate the Δ by a maximum step height and 5% of the step height (minimum height which is maximum 5% of the step height). An output value of the sharpness Δis used in a coefficient calculator 207 to obtain a filter coefficient for a sharpness filter.

Title: Detection of nucleic acid by fluorescent quenching
Inventor: NADEAU JAMES G
IPC: C12Q1/68
Filed: 1998-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting a nucleic acid and a target sequence, especially the method for detection using a fluorescent quenching. SOLUTION: A nucleic acid for detection is used for detecting a target sequence of a nucleic acid with a fluorescent quenching system. The nucleic acid for detection contains at least two oligonucleotides and is partially a single strand and partially a double strand. In a donor/acceptor dye pair, either one of the two dyes of the donor/acceptor dye pair is bound to the first oligonucleotide and the other is bound to the second oligonucleotide. When the first and the second oligonucleotides are base paired, both approach to quench the donor fluorescence. When the target is absent, a part of the detected oligonucleotide retains the form of the single bond and a part thereof retains the form of the double strand.  When the target is present, the nucleic acid for the detection is replaced from the first nucleotide and the distance between the donor and the acceptor dyes is increased to cause a change in fluorescence.
