Title: Loudspeaker talking device
Inventor: FURUKAWA HIROMOTO
IPC: H04M1/60
Filed: 1991-02-28
Abstract: PURPOSE:To suppress howling in a short time and to ensure stable operation even when a change in an echo path rapidly takes place. CONSTITUTION:The device is provided with a speaker 1, a 1st echo canceller 3 erasing echo between microphones 2, and a 2nd echo canceller 4 cancelling the echo caused by a 2/4-wire converter 5.

Inventor: AOSAKI RIYOUJI
IPC: C12N15/09
Filed: 1994-02-07
Abstract: PURPOSE:To provide a method for clearly and repeatably detecting the point mutation of a DNA. CONSTITUTION:A method for detecting a point mutation in a specimen DNA comprises applying the specimen DNA to a gene-multiplying method using both a normal type primer and an abnormal type primer and detecting whether the specimen DNA is multiplied or not, when each primer is used. In the method for detecting the point mutation of the DNA, the 3'-terminals of the normal type primer and the abnormal type primer correspond to nucleotides, respectively, in which the presence of the point mutation is estimated. The normal type primer has a base sequence perfectly complemental to the end region of the multiplication region of the normal type DNA except the second nucleotide base from the 3'-end of the primer, and the abnormal type primer has a base sequence perfectly complemental to the end region of the multiplication region of the abnormal type DNA except the second nucleotide base of the 3'-end of the primer.

Filed: 1990-02-15
Abstract: PURPOSE:To attain a stable electric connection and also to enable execution of stable measurement for a long period even at a deep place by applying a pressure to an internal liquid by an actuating pressure of a weight, irrespective of the outside pressure of a liquid to be inspected. CONSTITUTION:The quality of water is measured in a state wherein an internal liquid inside a composite electrode 1 having a glass electrode and a comparison electrode put in one is made to flow outside continuously from a liquid communication element 3. On the occasion, a weight 30 is fitted movably up and down to a diaphragm 29 which is provided inside a cylinder 14 so that it covers a passage. The inside of the cylinder 14 is divided in a liquid-tight manner by the diaphragm 29, and an upper-side chamber 31a communicates with the outside through a passage 34 of a liquid to be inspected. On the occasion of measurement, the internal liquid is filled up inside a lower-side chamber 31b and an outer tube 10, the diaphragm 29 and the weight 30 are thereby pushed upward, and a device is sunk in the water. While a balance is brought forth by the liquid to be inspected which comes in through the passage 34, accordingly, a pressure is increased by the weight 30 and the internal liquid continues to flow out irrespective of the outside pressure of the liquid to be inspected. Thus, the liquid to be inspected does not flow reversely into the internal liquid and stable measurement can be executed.
