An absorptiometer is provided which can be used in a state where it is immersed in a liquid to be measured without using an absorbance-measuring cell, and which is insusceptible to disturbance light. The absorptiometer is constructed of a sensor unit (10) directly put into the liquid to be measured, a body unit (20), and wirings (31, 32). The censor unit (10) includes a housing (14), and a LED light source (11) and a photodiode (12) are attached in an opposing manner to this housing (14), with a predetermined length L provided at the distance between the tips of the LED light source (11) and the photodiode (12). The distance L therebetween corresponds to the thickness of the cell in a conventional absorptiometer. A drive current including an alternating current component of a predetermined frequency is input to the LED light source (11), and the output of the photodiode (12) is, after amplified by an amplifier (13), subjected to extraction therefrom of a frequency component in synchronization with the above predetermined frequency, and the absorbance of the liquid to be measured is determined based on the output of this phase detection circuit.

A liquid chemical supply system that performs accurate pressure feedback control and controls the discharge flow rate of liquid chemical with high precision, even when the pressure setting value of the operation pressure differs due to changes in the type of liquid chemical, includes a pump having a pump chamber and an operation chamber separated by a diaphragm comprised of a flexible membrane. The intake and discharge of liquid chemical is performed in accordance with the change in pressure inside the operation chamber. An electro-pneumatic regulator supplies operation gas pressure to the operation chamber. A plurality of pressure sensors having different pressure detection ranges is provided for detecting the operation gas pressure. A controller selectively employs any of the detection results of the plurality of sensors in accordance with the pressure setting value of the operation air that is set for each use, and performs pressure feedback control.

Surface-coated aluminum oxide nanoparticles capable of being uniformly blended into polycarbonate resin in a good dispersed state while maintaining a molecular weight of the polycarbonate resin at a specific level or more. Surfaces of the surface-coated aluminum oxide nanoparticles are coated with a dispersant and a silylation reagent. In a case where a monochromated Al-Kα ray is irradiated onto a sample surface by using an X-ray photoelectron spectroscope, when a surface element composition is calculated from an obtained photoelectron peak area, contents (atm %) of nitrogen atoms, thiol-derived sulfur atoms, and halogen atoms in the surface-coated aluminum oxide nanoparticles are individually 2 or less, and when the surface element composition is calculated from obtained photoelectron peak areas of Al2p and Si2s, a concentration (mol %) of silicon atoms with respect to aluminum atoms is 0.05 to 30.
