Abstract: The present invention provides: a multilayer film structure which has high crystallinity and planarity; and a method for producing this multilayer film structure. This multilayer film structure is provided with: an Si (111) substrate; a first thin film that is arranged on the Si (111) substrate, while being formed of a nitride material and/or aluminum; and a second thin film that is arranged on the first thin film, while being formed of a nitride material. An amorphous layer having a thickness of 0 nm or more but less than 1.0 nm are present on the Si (111) substrate; and the full width at half maximum (FWHM) of a rocking curve of the (0002) plane at the surface of this multilayer film structure is 1.50° or less.

Abstract: An inflatable cuff for pressing a body portion of a living subject by being wound and inflated around the body portion, in measuring a blood pressure of the subject, the cuff having (a) a first group of graduations provided on a major surface of the cuff, the major surface being adapted to be visible when the cuff is wound around the body portion of the subject, so that the first group of graduations are used for measuring a circumferential length of the body portion; and (b) a second group of graduations provided on the major surface of the cuff, the graduations of the second group corresponding to the graduations of the first group, respectively, so that the cuff wound around the body portion of the subject is fixed at one of the graduations of the second group which corresponds to one of the graduations of the first group which indicates the measured circumferential length of the body portion.

Abstract: A pressure pulse wave transmitting sheet for being interposed between a skin surface of a living subject such as a patient and a pressure pulse wave sensor set on the skin surface in pressed contact therewith, the sensor having a press surface in which at least one pressure sensing element is provided and which is pressed against the skin surface so that the at least one pressure sensing element detects a pressure pulse wave transmitted from an artery of the subject underlying the skin surface, to the press surface via the sheet, the sheet being formed of an elastic material having a hardness substantially equal to a hardness of human being's skin.
