Publication number: US20220028906A1
Application number: 17/499,135

Abstract:
Provided a semiconductor light detection element including: a semiconductor portion having a front surface including a light reception region that receives incident light and photoelectrically converting the incident light incident on the light reception region; a metal portion provided on the front surface; and a carbon nanotube film provided on the light reception region and formed by depositing a plurality of carbon nanotubes. The carbon nanotube film extends over an upper surface of the metal portion from an upper surface of the light reception region.

Publication number: US20210401312A1
Application number: 17/469,737

Abstract:
A viscoelastic characteristics acquisition device is a device that acquires viscoelastic characteristics of a blood vessel of an inspection target, and includes a pulse wave acquisition unit that acquires a time waveform corresponding to a volume pulse wave of the inspection target, a spectrum acquisition unit that acquires a volume pulse wave spectrum by performing Fourier transform on the time waveform, an input unit to which values corresponding to maximum blood pressure and minimum blood pressure of the inspection target are input, and an analysis unit that acquires the viscoelastic characteristics on the basis of the values corresponding to the maximum blood pressure and the minimum blood pressure and the volume pulse wave spectrum at a frequency equal to or higher than a frequency corresponding to the pulse of the inspection target.

Publication number: US20210398790A1
Application number: 17/465,173

Abstract:
A surface-assisted laser desorption/ionization method according to an aspect includes: a first process of preparing a sample support (2) having a substrate (21) in which a plurality of through-holes (S) passing from one surface (21 a) thereof to the other surface (21 b) thereof are provided and a conductive layer (23) that covers at least the one surface (21 a); a second process of placing a sample (10) on a sample stage (1) and arranging the sample support (2) on the sample (10) such that the other surface (21 b) faces the sample (10); and a third process of applying a laser beam (L) to the one surface (21 a) and ionizing the sample (10) moved from the other surface (21 b) side to the one surface (21 a) side via the through-holes (S) due to a capillary phenomenon.
