A stacked ultrasound vibration device is provided with a plurality of piezoelectric bodies between two mass materials, in which brazing materials with an elastic constant smaller than elastic constants of the two mass materials and the plurality of piezoelectric bodies are used to bond the plurality of piezoelectric bodies as similar material bonding portions by a first metal bonding layer with a first thickness and to bond the plurality of piezoelectric bodies and the mass materials as dissimilar material bonding portions by a second metal bonding layer with a second thickness thicker than the first thickness.

Stacked ultrasound vibration device and ultrasound medical apparatus

An ultrasound unit includes: ultrasound elements each including a plurality of ultrasound cells formed on a substrate including a semiconductor, the plurality of ultrasound cells each including an upper electrode having a ground potential and a lower electrode to which a drive signal is applied, the upper electrode and the lower electrode being arranged facing each other via a cavity and thereby forming a first capacitor; a package member in which the plurality of ultrasound elements are disposed, the package member having a ground potential; and an insulation member disposed between the package member and each of the ultrasound elements. A second capacitor is formed as a result of the insulation member serving as a gap, and a capacity of a third capacitor serially connected to the second capacitor is smaller than a capacity of the second capacitor.

Ultrasound unit and ultrasound endoscope

An image pickup unit includes a dioptric system that reflects a luminous flux of an optical image incident on an optical lens group and performs optical path conversion, an image sensor in a bare state that is joined to the dioptric system, and includes a light receiving element that forms the optical image, and a light shielding member that is placed to be opposed to and cover at least surfaces around an optical axis of the optical lens group, except for a joining surface of the dioptric system to the image sensor, so that an air gap apart from the image sensor by a predetermined distance is provided, shields incidence of a harmful light onto the light receiving element, and is formed from a metal thin film.

Image pickup unit for endoscope

An object of the present invention is to readily initiate an operation of a capsule medical apparatus which is inserted into a subject and executes a predetermined function. In a capsule endoscopeaccording to the present invention, a reed switchconnected to a power supply unit and a function executing unit is arranged parallel to a direction of a longitudinal axis t of a capsule-like casingin the substantially cylindrical capsule-like casingof the capsule endoscope. A pair of movable electrodes of the reed switchoperates according to magnetic induction of a magnetic field of a magnetapplied substantially parallel to the direction t of the longitudinal axis of the capsule-like casing, and come into contact with each other. As a result, power supply from the power supply unit to the function executing unit is allowed.

Capsule medical apparatus and current-carrying control method

A semiconductor package of the invention comprises: a semiconductor element provided with a circuit element on one surface of a semiconductor substrate; an external wiring region provided on an other surface of the semiconductor substrate; a support substrate disposed on the one surface of the semiconductor substrate; an electrode pad disposed on the one surface of the semiconductor substrate; and a through-electrode which extends from the electrode pad through to the other surface of the semiconductor substrate.

Semiconductor package with through-hole

Disclosed herein is SPM cantilever having a support portion, a lever portion extended from the support portion and a probe portion formed at a free end of the lever portion, said probe portion having a generally plate-like form and the probe portion having an additionally sharpened terminal end portion. The terminal end portion has its length greater than the plate thickness thereof and is reduced in thickness toward a tip of the terminal end portion, and the tip is located inwardly of the planes extended from the front and back sides of a base portion of the plate-like probe portion.

SPM cantilever and fabricating method thereof

A silicon nitride film is formed all over the surface of a cantilever prepared as including a support portion made by processing single-crystal silicon wafer, a lever portion extended from the support portion, formed with a controlled thickness from single-crystal silicon, and a probe portion made of single-crystal silicon disposed toward the free end of the lever portion with having its probe axis perpendicular to the lever portion, so as to have a greater film thickness on the side face of the probe portion toward the free end of the lever portion, thereby constructing SPM cantilever of configuration where the terminal end portion of the probe portion is tilted toward the free end by a certain angle &#x3b8; with respect to the probe axis. The SPM cantilever thereby can be achieved as capable of measuring surface conditions always at high resolution correspondingly to measuring condition or sample shape.

SPM cantilever

A cantilever for Scanning Probe Microscopy including: a support portion; a lever portion extended from the support portion; and a probe portion provided at an free end of the lever portion, said probe portion being configured by two triangular thin plates each having one side respectively being one of the different two sides of a V-like notch formed on the free end of the lever, where the thin plates are caused to face each other while having the other side in common. The cantilever for Scanning Probe Microscopy is thereby achieved as having a probe portion which is light in weight and high in rigidity and is readily positioned in alignment and by which measurement at high resolution is steadily possible
