Abstract:
In an IF signal processing circuit in an FM receiver, distortion introduced by an IF filter is eliminated without degrading a selection characteristic thereof. The circuit includes a front end which converts an FM-RF signal into a first IF signal; an IF filter; an FM detector which detects the first IF signal which has passed through the IF filter; an FM modulation circuit which outputs an FM modulation signal in accordance with a detection output of the FM detector; a mixer for mixing the FM modulation signal with the first IF signal and providing a second IF signal; and another mixer for mixing the second IF signal with the FM modulation signal to convert into the first IF signal. The first IF signal thus converted is delivered to an FM detector.
Abstract:
Whether there is a defect such as chipping of a die or separation of a resin in a wafer level package is electrically detected. A peripheral wiring is disposed along four peripheries of a semiconductor substrate outside a circuit region and pad electrodes P1-P8. The peripheral wiring is formed on the semiconductor substrate and is made of a metal layer that is the same layer as or an upper layer of a metal layer forming the pad electrodes P1-P8, or a polysilicon layer. A power supply electric potential Vcc is applied to a first end of the peripheral wiring, while a ground electric potential Vss is applied to a second end of the peripheral wiring through a resistor R2. A detection circuit is connected to a connecting node N1 between the peripheral wiring and the resistor R2, and is structured to generate an anomaly detection signal ERRFLG based on an electric potential at the connecting node N1.
Abstract:
An antibody binding to IPC was obtained by using an animal cell in which a cell membrane protein associatable with ILT7 was co-expressed as an immunogen. The antibody of the invention has a high specificity which allows immunological distinction between other ILT family molecules and ILT7. The anti-ILT7 antibody of the invention bound to IPC and inhibited the activity thereof. With the anti-ILT7 antibody of the invention, the IPC activity can be inhibited and an interferon-related disease can be treated or prevented. ILT7 expression is maintained even in IPC in the presence of IFNα. Therefore, an inhibitory action of IPC activity by the anti-ILT7 antibody can be expected even in an autoimmune disease patient with an increased production of IFNα.
Abstract:
Disclosed is an apparatus for forming a device having a fine structure, the apparatus including a high intensity ion source. The apparatus can be used to form fine grooves and/or a fine film, by supplying a reactive gas to the surface to be etched or coated while irradiating a focused ion beam on the surface. A laser or electron beam can be irradiated on substantially the same axis as that of the focused ion beam, whereby defects arising due to ion beam processing can be repaired. The apparatus can further include ion beam current detection and measurement structure to determine when a predetermined thickness of coating or depth of etching is achieved. The apparatus can include multiple chambers sequentially holding the surface treated, and can include a scanning electron microscope for scanning the surface being coated or etched.
Abstract:
A spouted bed granulation process in which the average particle size of the final product is controlled by employing, as seed particles fed to the granulator, a mixture of particles of at least two different average particle sizes and changing the mixing ratio of the respective particles.
Abstract:
In order to expand the product between the transmission length and the transmission bandwidth of an optical fiber for use in the optical communication and to facilitate the connection between the optical fibers, the optical fiber is made of transparent materials of three concentric layers of a core whose refractive index gradually decreases in the radial direction from the center, an intermediate layer which has a uniform refractive index lower than the varying refractive index of the core, and a cladding which has a uniform refractive index substantially equal to the lowest refractive index of the core.
Abstract:
A carbon component having a hole therein and an outer surface covered with a ceramic coating, and a method for manufacturing the carbon component are provided. The carbon component includes two carbon plate members joined together. The hole is defined by a groove formed on a mating surface of at least one of the carbon plate members and a mating portion of the other of the carbon plate members, which opposes the groove. An inner surface of the hole including a surface of the groove is entirely covered with a ceramic coating.
Abstract:
An electronic part positioning jig is provided, which includes a positioning member which is made of carbon and positions an element part, and a platform which supports the positioning member on a plane. The platform includes a frame member which receives the positioning member, and a body portion which fixes the frame member. The positioning member is sandwiched between the frame member and the body portion so as to be displaceable on the body portion by the frame member being fixed to the body portion by a joining member.

Abstract:
BST2 antibodies were selected by using as an indicator the binding between BST2 antibodies and various splicing variants of human BST2 antigen. As a result, the present inventors successfully obtained BST2 antibodies that specifically recognize BST2D, which has been reported to be expressed at high levels in cancer cells. The antibodies of the present invention specifically bind to cells expressing BST2D. Non-specific antibody binding to non-target tissues, which results in the decrease of antibody concentration in blood, can be prevented by using the antibodies of the present invention therapeutically. Alternatively, the present invention provides diagnostic agents comprising an antibody of the present invention, which specifically detect tissues expressing BST2D.
