Title: Dispenser
Inventor: YAHIRO KANJI
IPC: G01N1/00
Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To provide a dispenser in which a liquid sample requiring cold insulation can be supplied efficiently while simplifying a cold insulation facility. SOLUTION: In a dispenser for sucking a liquid sample from a reservoir 5 by means of a dispensation head 7 having a plurality of dispensation chips 8 and delivering it to a microplate 4, a liquid sample 19 contained in a preservation container 18 is preserved in a preservation unit 17 and when it is supplied to the reservoir 5, the liquid sample is sucked by means of a pump 15 and supplied from the delivery nozzle 11 of a delivery unit 10 to the reservoir 5. Since a cold insulation box for preserving a large number of microplates 4 is not required and a dispensation stage does not require a cooling station, the liquid sample can be supplied efficiently while simplifying the cold insulation facility.

Filed: 1994-11-24
Abstract: PURPOSE: To provide a fixing device capable of securing the smooth passing of copying paper without changing the advance position or the ejection position of the copying paper to/from a nip part between a pair of rollers even when the center distance between the pair of rollers is changed so as to adjust pressure force against the copying paper.

Title: Semiconductor acceleration sensor
Inventor: KAMIYANAGI KATSUMICHI
IPC: G01P15/12
Filed: 1990-10-26
Abstract: PURPOSE:To obtain a sensor having a large damping effect to a weight by connecting the weight to a fixing frame with a cantilever, and by forming the gap between the weight and the fixing frame to have a given dimension except the cantilever part. CONSTITUTION:A connected body of a weight 1, a beam 2, and a fixing frame 3 all of which are made up of a semiconductor are fixed to a base 4 on its undersurface and to a sealing cover 7 on its upper surface keeping a gap g between them so as not to be brought into contact with the weight 1, so that a closed vessel 5 is formed by the base 4, the fixing frame 3 and the sealing cover 7, and therein a sealed fluid 6 is enclosed. And by measuring the deflection of the beam 2, acceleration is detected. Since the gap between the weight 1 and the fixing frame 3 is formed to have a given dimension, when an acceleration is applied, it is damped by the viscous resistance of the sealed fluid 6 flowing through the gap of the given space, and since the gap can be reduced within the range that the weight 1 is not brought into contact with the fixing frame 3 without exerting an influence upon the performance of the sensor, damping effect can be sufficiently increased.

IPC: C21C1/02
Filed: 1986-12-08
Abstract: PURPOSE:To rapidly advance de-phosphorizing reaction at initial stage in operation period and at the same time to advance desulfurization by changing dipping depth of a lance in accordance with the progress from the initial stage to the end stage of injection operation. CONSTITUTION:The injection operation is executed by injecting solid oxide containing iron oxide, such as iron ore, mill scale, sintering ore, and mixing material of refining agent, etc., having lime as main composition by using carrier gas, such as Ar gas, in molten iron. In this case, the operation is executed by changing the dipping depth of injecting lance, so as to become deeper toward depth direction in accordance with progress from the initial stage to the end stage in the operation period. By this method, the de-phosphorization is effectively executed without retarding de-phosphorization at the initial stage, and also at the same time, desulfurizing reaction is carried out. Further, foaming during the above treatment is restrained. And also, as the contacting position between the molten iron, slag and the lance is varied by changing the dipping depth of lance during the operation, the erosion of the lance can be reduced.
