Title: Biological signal processing device and biological signal processing program
Inventor: SATO ATSUSHI
IPC: A61B5/11
Filed: 2020-03-30
Abstract: The purpose of the present invention is to accurately detect biological signals.　The reflected response of a microwave emitted to a living body includes an amplitude component and a phase component. Ideally, it is sufficient that the reflection component hv(t) from the living body is analyzed. However, the reflection response component h(t) includes not only the reflection component hv(t) from the living body but also the reflection components hf(t) from objects other than the living body such as walls and furniture. This causes displacement of the origin point for analysis from the origin point O, and the displacement as a signal error affects the detection accuracy. In view of this, in the present invention a signal processing device 4 determines a virtual origin point O' as a reference for analyzing hv(t) by analyzing an obtained signal, determines the phase component and the amplitude component from the virtual origin point O', and thereby can obtain a signal more suited for a phenomenon than those obtained by conventional methods using a filter. More specifically, in order to determine the phase and amplitude from the virtual origin point O', the signal processing device 4 uses the difference between the origin point O and the virtual origin point O' as an offset amount and offsets h(t) using the amount.

Inventor: TAKARA NAOKATSU
IPC: F16C27/02
Filed: 2020-04-07
Abstract: A journal bearing (100), which supports a rotating shaft (900) of a rotating machine, comprises an oil supply nozzle (30) having an oil distribution part (301) that extends in the axial direction of the rotating shaft and supplies lubricating oil (800), and a pad (21) that is provided to the rear of the oil supply nozzle in the rotating direction of the rotating shaft and that rotatably supports the rotating shaft. The inner peripheral surface of the pad, which faces the outer peripheral surface of the rotating shaft, has an opening surface (21a1) where the radial-direction space between the inner peripheral surface and the outer peripheral surface of the rotating shaft decreases rearward in the rotating direction from the front-end surface of the pad at the front in the rotating direction of the rotating shaft. Between the oil distribution part and the pad there is a bubble discharge path (40) that discharges bubbles (801) mixed in the lubricating oil. It is therefore possible to obtain a journal bearing in which air bubbles contained in the oil can be removed and the gap can be efficiently filled with oil using a small amount of oil supply, and a rotating machine in which said journal bearing is used.
