Title: Elevator doorway gap closing device
Inventor: SUDO OSAMU
IPC: B66B13/28
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To prevent small material from falling into an elevator shaft and allow a wheelchair or the like to be smoothly put in and out of a car by moving a closing body by torque of a driving motor, transmitted through connecting means, so as to close a gap between a car sill and a landing sill. SOLUTION: A current is fed to a driving motor simultaneously with opening of a door 7 of a car 1 landed on a landing 2. The driving force is transmitted to a pair of driving discs 13 through a driving shaft 14 and the like, so that the driving discs 13 are rotated clockwise, and a roller 16 is also rotated together. As the roller 16 is rotated, the roller 16 pushes up a bracket 17 while rolling in an oblong hole 17a of a bracket 17, and a closing body 8 fixed to the bracket 17 is put in upward oblique linear motion. When the closing body 8 reaches the upper face of a car sill 6, the bracket 17 comes in contact with an upper limit switch 9, and a current to the driving motor is cut off by the upper limit switch 9. A brake therefore acts upon the driving motor, and the closing body 8 is maintained in its position.

Title: Detection of mutation
Inventor: MITOMA YOSHITAMI
IPC: G01N33/58
Filed: 1990-05-28
Abstract: PURPOSE:To detect mutation of base sequence for a short time without using any special device, by making double-stranded nucleic acid having a specific base sequence to single-stranded nucleic acid, mixing said nucleic acid with an immobilizing nucleic acid probe in a column, washing the column and isolating the sample nucleic acid by adding a developing solution. CONSTITUTION:In detecting the existence of mutation in a specific base sequence, a double-stranded nucleic acid containing the specific base sequence is made to a single-stranded nucleic acid. Next, a nucleic acid probe immobilized to a solid phase complementary to the specific base sequence or complementary at a mutation- containing specific sequence in a case of having mutation in a specific sequence, is mixed with a sample nucleic acid in a column filled with said solid phase. Finally, resultant system is left under a condition capable of stably forming hybrid. Nucleic acid not formed hybrid with the nucleic acid probe is removed by adding a washing solution, as necessary, then a developing solution containing a factor reducing the stability of the hybrid is added to the column, at a temperature at which the hybrid is stable to isolate the sample nucleic acid from the nucleic acid probe. Thus, by measuring the value of said hybrid stability-reducing factor or the necessitated time, the presence of mutation can be detected.

Title: Mass flow-rate meter
Inventor: OGAWA YUTAKA
IPC: G01F1/84
Filed: 1986-06-11
Abstract: PURPOSE:To prevent effects of mixed-phase flow, by dividing a flow to a flow- rate meter into equi-quantity streams and allowing them to flow in the mutually opposite directions into branching pipes of the same shape and dimensions set side by side opposedly located one against the other with the specified distances between them. CONSTITUTION:A mixed-phase flow of quantity Q containing bubbles flows through a conduit A and is branched at B1, B2 into branching pipes 10, 20. A pressure loss is created between A, Q by a flow joining at points F1, F2 to a flow pipe G after flowing through a pipe 10 (or 20) branched into Q/2 at B1 (or B2) in the direction of an arrow A' (or B'). By this arrangement, sizes of the bubbles contained in the fluid grows toward the G-side and sine- motion driving of amplitude + or -m with the angular speed in the same direction around each of axis Y1, Y1' and Y2, Y2' is effected. As the result, coriolis moments are generated in the opposite directions around axes X1, X1' and X2, X2' of the pipes 10, 20. Accordingly, the coriolis moments are doubled and changed amounts caused by unbalanced fluid density are eliminated.
