Abstract: PURPOSE:To shorten time for reaction of a reagent by heating a distributing nozzle including the vicinity of a discharge port thereof by providing an ultrasonic vibrator which causes a heat by friction in resonators amplifying ultrasonic vibration, a flow passage and the nozzle for sucking and discharging a reagent and a specimen. CONSTITUTION:Ultrasonic vibration generated from a laminate-type piezoelectric element is enlarged by resonators 4 and 40 and transmitted to a flow passage pipe 10 and a distributing nozzle 11. An internal friction occurs in a small- diameter part 9 of the resonator and in the flow passage pipe 10 and the distributing nozzle 11 and a temperature rises instantaneously. Accordingly, a part whereon the flow passage pipe 10 is wound round and a liquid, such as a specimen or a reagent, which is sucked up by the distributing nozzle 11 can be heated to a set temperature in a short time. In this case, adjustment of the temperature of the liquid in a large quantity is also enabled by increasing the number of winding of this flow passage pipe 11 or by winding it in a number of stages.

Title: Measurement of ionization radiation
Inventor: IYURI MIHAIROBUICHI PURESUKACH
IPC: G01T1/02
Filed: 1988-11-10
Abstract: PURPOSE: To measure radioactive rays accurately over a wide range of dose and temperature range by irradiating a test piece with reference ionization radioactive rays before applying ionization radioactive rays to the polyethylene test piece and then heating, deforming, and then cooling the test piece while retaining the deformed state. CONSTITUTION: Reference ionization radioactive ray with a dose of 50-1,000KGy irradiates a polyethylene test piece. Then, it is heated at 383-573K. The heated polyethylene can be plastically deformed without losing its binding property and is deformed and machined at a ratio of 5-800% for the initial dimension of the test piece. In the case of the second irradiation of the test piece due to radioactive rays to be measured with an extremely high power, an excessively rapid shape memory effect appears in the test piece so that the test piece is restricted by a fixed clamp while maintaining a first deformation state to prevent it, the test piece is removed and a second heat treatment is performed after the second irradiation by ionization radioactive rays.  To improve measurement accuracy by a low measurement dose, a polyethylene crosslinking sensitizer that is radiated into the test piece is introduced after the first irradiation.

Title: Fluid vibration detection sensor
Inventor: MIYAZAKI YOSHIRO
IPC: G01F1/20
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To obtain small-sized simple structure of identical volume, and maintain high sensitivity without using a noise preventing means, by arranging a pair of chambers on both sides of a film and connecting introducing paths with the respective chambers from fluid vibration detection ports. SOLUTION: A fluid vibration detection sensor 10 is constituted as a single body structure in which a pair of chambers 12a, 12b are arranged interposing a film (diaphragm) between them, thereby, miniaturizing the sensor 10. The respective pressure guide paths can be symmetrically formed which reach both sides of the diaphragm 13 from two fluid vibration detection ports, via introducing paths, introducing ports 15a, 15b and chambers 12a, 12b, so that the respective pressure guide paths can be easily formed to have equal lengths and the same volume, and noise in a pipe is transmitted to the diaphragm 13. Since a sheet of diaphragm 13 is used for a pair of the chambers 12a, 12b, it can be avoided that a potential difference is generated between structures.  As a result, the resistance to circumferential noise and the S/N of a sensor output are improved, and high sensitivity of the sensor 10 can be maintained.
