Abstract: A new type of optical pressure sensor with adjustable sensitivity is proposed based on the fiber Bragg grating (FBG). In this technique, the pressure changes the length of a metal bellows which is placed behind a spring. The fiber grating is fixed over the bellows between a fixed position and the connection point of bellows and spring. The wavelength change of FBG is caused by the change in the bellows length; however, the spring controls the total length expansion of the bellows. It will bring two benefits: first it is easy to change the pressure sensing range by changing the spring rate; and secondly the spring improves the linearity of the wavelength sift due to the pressure. The FBG is installed outside of the bellows and is not in contact with the material in which the pressure should be measured (gas or liquid) in contrast with other pressure sensors where the FBG is inside the bellows.

Abstract: An automatic analyzer uses probes for detecting liquid levels based on a capacitance detection method. Erroneous detection of liquid levels due to interference caused by the frequency difference of oscillators is reducted. When frequencies f1 and f2 of respective detector ocillators, which are originally equal to each other, are different by approximately several Hz from each other due to a manufacturing variation, oscillation waveforms are added to liquid level detection voltages, causing a premature determination that the probes have contacted the liquid surface before actual contact therewith. By setting the difference between the frequencies f1 and f2 of the detector oscillators to be in the range of several kHz, an oscillation waveform corresponding to the difference between the frequencies is added to the detection voltages, but the amplitude values of the high-frequency components are attenuated by high-frequency attenuators, thereby ensuring accuracy in the liquid level detection.

Abstract: An infinitely variable transmission (IVT) to provide a continuous output-to-input speed ratio from zero to a certain value is designed, and its working principle is illustrated. It is a geared IVT (GIVT), since its function to achieve the continuously varied speed ratio is implemented by gears.

Racks and pinions, whose motion is controlled by planetary gear sets, are used to change the crank length when the cranks are rotating. One-way bearings are used to rectify the output speeds from different crank-slider systems to obtain the output speed of the GIVT. Since the crank-slider systems can introduce variations of the instantaneous speed ratio, a pair of noncircular gears is designed to minimize the variations. A direction control system is also designed for the GIVT using planetary gear sets.

Abstract: An object of the present invention is to provide a method for producing an alloy recycled material by effectively removing carbon from a carbon-containing alloy, which is produced as scrap or sludge of an R—Fe—B based permanent magnet, a used magnet, or the like.
