Abstract:
A physical quantity sensor (100), which can detect multiple physical quantities simultaneously has flexibility or bendability over the entire body thereof. The sensor (100) has a first electrode layer (2) formed on a substrate (1) and first and second piezoelectric elements (3a, 3b) arranged in parallel on the electrode layer (2). Two additional electrode layers (4a, 4b) are formed on the piezoelectric elements (3a, 3b). The substrate (1), the electrode layer (2), first piezoelectric element (3a), one of the additional electrode layers (4a) and protective layers (5a, 5b, 5c, 5d, 5e) constitute a first physical quantity detection unit (6), and the substrate (1), the first electrode layer (2), the second piezoelectric element (3b) and the other additional electrode layer (4b) (a fourth electrode layer) constitute a second physical quantity detection unit (7).

Abstract:
The present invention provides a percutaneous terminal having a substrate thereof flocked with fibers having bio-affinity, and thereby being able to adhere tightly to a living body, a medical instrument to be placed in the body, and a production method and a production apparatus of the percutaneous terminal and the medical instrument to be placed in the body. The percutaneous terminal according to the present invention is one which the surface of the substrate is flocked with bio-affinitive short fibers (e.g. hydroxyapatite complex particles), therefore the bio-affinitive short fibers are risen perpendicular to or substantially perpendicular to the surface of the substrate. As a result, an area of the bio-affinitive short fibers coating a unit area of the substrate of the percutaneous terminal to the unit area of the percutaneous terminal substrate is considerably elevated and, in its turn, the adhesiveness of the percutaneous terminal to biological tissues is improved. Thus, it is possible to stably fix to the living body a medical device such as a catheter or the like which has the percutaneous terminal. The medical instrument according to the present invention is also flocked with the short fibers as described above, therefore it is possible to stably fix to the living body the medical instrument to be placed in the body.

A method for growing III-V nitride films having an N-face or M-plane using an ammonothermal growth technique. The method comprises using an autoclave, heating the autoclave, and introducing ammonia into the autoclave to produce smooth N-face or M-plane Gallium Nitride films and bulk GaN.
Abstract:
A method which visualizes the distribution of a local electric field formed near a sample 2 is disclosed. A primary electron beam 1 which passes through the local electric field formed near the sample 2 is deflected by the local electric field, secondary electrons which are generated and emitted from a detection element provided downstream of an orbit of the deflected primary electron beam 1 are detected by a secondary electron detector 6, and an image formed based on the detected signal and a scanning electron beam image obtained by scanning the sample 2 are synthesized thus visualizing the distribution of the local electric field in multiple tones. Due to such an operation, it is possible to provide a method for visualizing the distribution of a local electric field in which the distribution of a local electric field can be obtained in multiple tone and in real time by performing image scanning one time using a usual electron beam scanning optical system.
Abstract:
The present invention provides a novel carbon-based material in which carbons different in property are combined in such a manner as to be applicable to a device. The carbon-based thin film provides a carbon-based thin film 10 including first phases 1 that contain amorphous carbon and extend in a film thickness direction, and a second phase 2 that contains a graphite structure and intervenes between the first phases 1. In the thin film, at least one selected from the group consisting of the following a) to e) is satisfied: a) the second phase contains more graphite structures per unit volume than the first phases; b) a density of the second phase is larger than that of the first phases; c) an electric resistivity of the second phase is lower than that of the first phases; d) an elastic modulus of the second phase is higher than that of the first phases; and e) in the second phase, a basal plane of the graphite structure is oriented along the film thickness direction.
Abstract:
A field-effect transistor or a single electron transistor is used as sensors for detecting a detection target such as a biological compound. A substrate has a first side and a second side, the second side being opposed to the first side. A source electrode is disposed on the first side of the substrate and a drain electrode disposed on the first side of the substrate, and a channel forms a current path between the source electrode and the drain electrode. An interaction-sensing gate is disposed on the second side of the substrate, the interaction-sensing gate having a specific substance that is capable of selectively interacting with the detection target. A gate for applying a gate voltage adjusts a characteristic of the transistor as the detection target changes the characteristic of the transistor when interacting with the specific substance.

Abstract:
A numerical data transfer section transfers numerical data and its format as input values for computation from a user program system to a library program system, gives it a name, and registers/manages it. In addition, a computation request section transfers information on the content of the computation from the user program system to the library program system. In library program system, a computing method determining section determine the types of library programs to be used and their execution sequence on the basis of the received information on the content of the computation. A computation-result transmitting section transfers results of execution from the library program system to the user program system in accordance with a request from a user. Accordingly, the user of the user program can more easily use library programs without having to pay attention to specific processes carried out by the library program system.
