High performance liquid chromatography(HPLC)using a multiwave detector possesses the advantage of being able to measure both the absorption spectra and the retention time. But conventional multiwave detector with diode arrays has lower sensitivity than commercial single wave UV detector with photomultiplier tubes and shows a marked decrease of sensitivity in the UV region below200n m. With our multiwave HPLC detection system, mechanical scanning with a rotary slit is conducted with a photomultiplier that has full sensitivity in the wavelength renge of160-650nm. And absorption due to oxygen below the200nm wavelength region has been inhibited by filling the optical system with nitrogen . This has resulted in an improvement in this system's detection sensitivity enabling it to measure in the UV region below200nm. Using this system, we tried out multiwave HPLC analysis for a number of clinical chemically important saccarides and amino acids without using some coloring reagents. As a result of this it was found possible to detect absorption peaks of each component below a wavelength of200nm, and the possibility of conducting qualitative analysis from the absorption spectra of the components was also demonstrated.

Recently, how to help bedridden people is becoming an urgent problem as the number of aged people is rapidly increasing in Japan. Especially, locomotive lifters and robots for the disabled are needed in order to transfer patients from a bed to a wheel chair, abathtub, a lavatory and so on. This paper describes an evaluation method of the locomotive lifters which can be applied to Japanese home and to the bodysize of Japanes epeople. A prototype lifter made in Denmark was reformed to adapt it to such Japanese circumstances. Next, mechanical stability and convenience in handling it were evaluated from the viewpoint of mechanical engineering and human engineering. Through this evaluation, it was found that the reformed lifter was useful in lifting and trnasferring Japanese patients inside hospitals.
