Abstract: PURPOSE:To simultaneously seal a lyophilized drug in a hollow tubular body having an opening part without breaking the shape of the drug, by interposing the drug on a gel substance. CONSTITUTION:A tube of polypropylene including fillers is cut thereby to form a hollow tubular body 2. The body 2 is dipped in a thrombin solution, frozen and dried, so that an excessive thrombin is removed. The hollow tubular body 2 encasing the thrombin is put in a blood collecting tube 4 which contains a suitable amount of an alpha-olefin/maleate copolymer series separating agent 3 to separate the blood serum at the bottom thereof, so that the apparent volume of the frozen and dried thrombin becomes a predetermined value. Moreover, a coat film of glass powders is put in the tube 4. An opening of the tube is sealed by a multilayer film 5 of an aluminum foil in vacuum. Accordingly, a vaccum blood collecting tube 1 to collect a required amount of blood is obtained. Since the blood is frozen fast and no fibrin is precipitated subsequent to the centrifugal separation of the blood, the tube is effective for inspections in an emergency.

IPC: H04Q11/04
Filed: 1988-04-19
Abstract: PURPOSE:To normally receive a high speed burst signal from respective slave stations, whose transmission loss is respectively different, without fail in a master station without using a high speed automatic gain control circuit by adjusting the transmitting level of a self-station transmitting level control circuit in correspondence to the transmission loss value, which is detected by a transmission loss detecting circuit, in the respective slave stations. CONSTITUTION:The signal transmission loss between the self-stations and a master station 51 is known for respective slave stations 521 to 52n and in correspondence to this value, the transmitting level of a transmitting level control circuit 56 in a self-station transmitting circuit 55 is adjusted. In the receiving end of the master station 5, the receiving amplitudes of transmitting signals, which come from the respective slave stations 521 to 52n, are caused to be an almost same value. Thus, since the burst-shaped transmitting signals from the respective slave stations 521 to 52n, whose transmission loss is respectively different, are automatically arranged to an almost same signal level in the receiving end of the master station 51, even when a transmitting speed goes to be high, the transmitting signals from the respective slave stations 521 to 52n can be received without fail in the master station 51 without using the high speed automatic gain control circuit.

During the period, the data of the position and the absorbance data as output of an averaging circuit 6 and the data of noise as output of an effective value circuit 8 are sampled and stored into corresponding addresses of respective memories M. Data of the memories M are read out to search data of positions (h) and (v) maximize the S/N ratio, namely, the ratio between the output of the circuit 6 and that of the circuit 8 and the data of the absorbance at the positions are compared with the maximum of the absorbance. When it exceeds 1/K of the maximum, the mechanisms Dh and Dv are driven to set the sample atomizing section F at the positions (h) and (v). This enables the analysis at the optimum position thereby improving the accuracy and efficiency of analysis.
