A plurality of ultrasonic transducer elements are arranged on the top surface of a probe, which is a concave spherical surface, so that ultrasonic beams transmitted from the ultrasonic transducer elements will intersect at a point coincident with the center of curvature of a curve delineated by the top surface. At this time, the acoustic lines conically propagate over a region beyond the point of intersection. Namely, the ultrasonic beams transmitted from the ultrasonic transducer elements pass through the point of intersection coincident with the center of curvature, and then conically and three-dimensionally propagate over the region beyond the point of intersection. Thus, acoustic lines are three-dimensionally transmitted to a wide region beyond an intercostal part of a physiological body or any other narrow space, and echoes returned from the region are received. Consequently, the wide region can be three-dimensionally monitored.

An apparatus for non-invasion heart monitoring includes electrocardiogram measuring means (1) for measuring electrocardiograms, pulse wave measuring means (2) for measuring pulse waves, and a CPU (30) for processing electrocardiogram signals derived from the electrocardiogram measuring means (1) and pulse wave signals derived from the pulse-wave measuring means (2). The CPU (30) detects the amplitudes of the pulse waves corresponding to the R waves of the cardiogram and the pulse wave propagation times, and computes a ratio (Nr/N) of the heart rate N and the heart rate Nr exclusive of the heart beats of wave deficits.

A biological gas sensor for measuring a carbon dioxide partial pressure in an alimentary canal while excluding the influences of hydrogen sulfide and/or weak acid is disclosed. The gas sensor comprises a sensor which has in the sensitive part thereof a bicarbonate buffer solution held by a gas permeable membrane and detects a carbon dioxide partial pressure based on the hydrogen ion concentration of the bicarbonate buffer solution, a liquid holding part which is formed of a gas permeable tube having in the inside thereof the sensitive part of the sensor, an isotonic solution which is held in the liquid holding part and is isotonic with the bicarbonate buffer solution, and a metallic member (e.g., a coil of copper wire) so that hydrogen sulfide entering the liquid holding part may react with the metal and precipitate.

A system, a method, and a program for predicting a processing shape by a plasma process by which a process state is measured on a realtime basis based on the result of which the processing shape is predicted. The system includes an apparatus condition DB 21, an incident ion DB 22, an incident radical DB 23, an actual measurement DB 24, a material property and surface reaction DB 25, a trajectory calculation unit 26, and a surface shape calculation unit 27. The trajectory calculation unit 26 calculates the trajectories of the respective ions incident on the surface of the substrate based on information and data obtained from the apparatus condition DB 21, the incident ion DB 22, and the incident radical DB 23 depending on the condition setting of the plasma processing apparatus 10, the respective pieces of data obtained from the actual measurement DB 24 depending on the condition setting of the plasma processing apparatus 10, and the respective pieces of data from the on-wafer monitoring sensor 11. Based on the calculation result by the trajectory calculation unit 26, the surface shape calculation unit 27 calculates the change of the shape by referring to the data stored in the material property and surface reaction DB 25.

A gas vane pump wherein a lubricant is intermittently introduced into a housing 10 during rotation of a rotor 40, through a lubricant supply passage 100 formed through the housing and the rotor, and the relative position between the rotor having a diametric hole 112 and the housing having a communication groove 130 is determined such that when the rotor 40 is placed at an angular position which is in the middle of a predetermined angular range relative to the housing 10 and in which the hole 112 is in communication with the groove 130, a point of contact between a vane 70 movably held by the rotor and the inner circumferential surface of the housing 10 is located at the lowest position of the inner circumferential surface, so that when the rotor 40 is stopped at an angular position within the predetermined angular range, the vane 70 divides the remaining lubricant mass into two portions, which are discharged at respective two different times one after the other, making it possible to reduce the load acting on the vane upon restarting of the vane pump.
摘要:
After an initial blood pressure measurement using a cuff 2 has been made, not only a pulse wave propagation time Tt is counted consecutively, but also a pulse wave propagation time change .DELTA.T is calculated every time the pulse wave propagation time Tt is counted and compared with a pulse wave propagation change threshold .DELTA.Ts. When the pulse wave propagation time change .DELTA.T exceeds the pulse wave propagation time change threshold .DELTA.Ts, not only a blood pressure value BPt is measured with the cuff 2, but also a pulse wave propagation time Tt.sub.1 is counted. If there are at least two sets of data, each set of data consisting of a blood pressure value BPt and a pulse wave propagation time Tt.sub.1, coefficients .alpha., .beta. specific to a subject are calculated from such two sets of data by a least-squares method. Then, the pulse wave propagation time change threshold .DELTA.Ts is calculated from the coefficient .alpha., and the current pulse wave propagation time change threshold .DELTA.Ts is updated.
