Abstract: In an ultrasound diagnostic apparatus for forming a Doppler image, a plurality of partial regions are set within a scan region in which Doppler information is obtained. A partial scan operation is performed a plurality of times in a repetitive manner in each of the partial regions. In each partial region, a set of dummy transmitting and receiving beams is formed immediately before formation of the first set of transmitting and receiving beams. As the receiving beam in the first set of the transmitting and receiving beams is affected by the dummy transmitting beam, the receiving conditions can be unified over a plurality of sets of transmitting and receiving beams. A set of dummy transmitting and receiving beams may be provided immediately before the first partial scan operation or formation of a set of dummy transmitting and receiving beams in such a case may be omitted.

Abstract: In order to receive satellite broadcasting (BS and CS) and terrestrial broadcasting (VHF and UHF), complicated wiring is required in a personal residence for transmitting broadcasting signals to a plurality of TV receivers while new distributors must be additionally set for installing additional TV receivers in a condominium previously provided with distributors limiting the number of settable TV receivers. The inventive millimeter wave communication system forms power supply paths by simply connecting a BS/CS antenna with a millimeter wave transmitter and connecting an electronic apparatus such as a TV receiver with a millimeter wave receiver through connectors or the like while transmitting/receiving broadcasting signals by millimeter wave radio communication without employing wires such as coaxial cables indoors.

The invention provides a manufacturing method of a semiconductor device where a semiconductor wafer attached with a glass substrate is cut with moving a rotation blade along a dicing region and has following features. A pair of alignment marks is formed facing each other over the dicing region on the semiconductor wafer. Then, when the rotation blade is to be aligned on a center of the dicing region, that is, on a centerline thereof in the cutting process, positions of the alignment marks are detected by a recognition camera, the centerline is calculated based on the detection result, and the rotation blade is aligned on the centerline to perform cutting.

Abstract: A manufacturing method of a semiconductor device formed in a chip size package is improved to enhance a yield and reliability. A window to expose first wirings is formed only in a region of a semiconductor substrate where the first wirings exist. As a result, area of the semiconductor substrate bonded to a supporting body through an insulation film and a resin is increased to prevent cracks in the supporting body and separation of the semiconductor substrate from the supporting body. A slit is formed along a dicing line after forming the window, the slit is covered with a protection film and then the semiconductor substrate is diced into individual semiconductor dice. Thus, separation on a cut surface or at an edge of the semiconductor dice, which otherwise would be caused by contact of the blade in the dicing can be prevented.

Abstract: A transfer rack 15 loaded with a seriate number of component supply cassettes 14 to be handled collectively is carried and retained on a truck 61 so that it can be taken in and out of the truck 61.

Abstract: A first glass substrate is bonded through a resin to a top surface of a semiconductor wafer on which a first wiring is formed. A second glass substrate is bonded to a back surface of the semiconductor wafer through a resin. A V-shaped groove is formed by notching from a surface of the second glass substrate through a part of the first glass substrate. A second wiring connected with the first wiring and extending to the surface of the second glass substrate is formed. A protection film composed of an organic resin and a photoresist layer to provide the protection film with an opening are formed on the second wiring by spray coating. A conductive terminal is formed by screen printing using the protection film as a solder mask. A cushioning material may be formed on the second glass substrate by spray coating.
