An optical fiber reinforcing heating device has a base part, to which a first lid part for covering a sleeve accommodation groove for containing a fiber reinforcement sleeve covering a fusion-splicing part of optical fibers is attached so as to be openable and closable. A pair of fiber holders for holding and securing the optical fibers are disposed on both end sides of the first lid part. Each fiber holder has a second lid part which is attached to a fiber container so as to be openable and closable and presses the optical fiber against the fiber container. A switch lever which is movable longitudinally of the sleeve accommodation groove is disposed on the upper face of the second lid part built in with a pin adapted to move in conjunction with the switch lever. A joint hole adapted to engage the pin is formed within the first lid part.

An optical fiber jacket remover draws a glass fiber out from a coating by cutting the coating in a jacket removing portion and moving an optical fiber holding portion away from a jacket remover main unit in a heated state. The jacket removing portion is provided with a heater supporting member on which a heater is mounted. The heater supporting member is accommodated in a recessed receiving portion formed in a case. A heat insulating space is formed between the recessed receiving portion and the heater supporting member. A side surface of the heater supporting member and an inside surface of a lateral wall of the recessed receiving portion are brought into contact with each other via a lateral rib formed on the heater supporting member, and the heat insulating space is thereby blocked.

A system for checking measurement results is provided with a urine qualitative analyzer for measuring the specific gravity of a urine, urinary particle analyzer for measuring urine conductivity, and a computer. The urine specific gravity measured by the urine qualitative analyzer, and the urine conductivity measured by the urinary particle analyzer are respectively transmitted to the computer. The correlative relationship between urine specific gravity and urine conductivity is stored in the memory of the computer, and the computer determines whether or not the received urine specific gravity and conductivity match the correlative relationship, and this determination result is output.

摘要:
A flow cell for a fluid particle analyzer comprises a narrow measuring liquid path, liquid introducing paths continuous to this measuring liquid path, liquid specimen nozzles disposed so that the front ends may be opposite to each other across the measuring liquid path, and sheath liquid inlets and waste liquid outlets disposed in the liquid introducing paths, respectively.The particle analyzer is designed to emit light to the liquid specimen flowing as a sheath flow in the measuring liquid path in the flow cell and detect the light from the particles individually. Since two liquid specimen nozzles are disposed opposite to each other, measurements from the liquid specimen discharging from one of the liquid specimen nozzles can take place while preparation of the other liquid specimen takes place, so that the analysis processing time can be notably shortened.
