Abstract: A method for recognizing an object image comprises the steps of extracting a candidate for a predetermined object image from an image, and making a judgment as to whether the extracted candidate for the predetermined object image is or is not the predetermined object image. The candidate for the predetermined object image is extracted by causing the center point of a view window, which has a predetermined size, to travel to the position of the candidate for the predetermined object image, and determining an extraction area in accordance with the size and/or the shape of the candidate for the predetermined object image, the center point of the view window being taken as a reference during the determination of the extraction area. A learning method for a neural network comprises the steps of extracting a target object image, for which learning operations are to be carried out, from an image, feeding a signal, which represents the extracted target object image, into a neural network, and carrying out the learning operations of the neural network in accordance with the input target object image.

Abstract: A method of making a semiconductor integrated circuit package (20) containing a chip (25) - and/or other active or passive electronic component(s) - enclosed in an encapsulation layer (24) which can be made thinner by abandoning the limitation of equality of thicknesses of electrically conductive lead frame fingers (21) and paddle (mounting pad, 22), the latter of which supports the chip (25) during fabrication of the package prior to encapsulation. As a result, a desired downset  d  of the paddle (22) with respect to inner portions (21.1) of the conductive fingers (21) automatically occurs without any bending of any die paddle support fingers (31), the latter of which support the paddle (22) during fabrication of the package (20). The paddle (22) advantageously is made by preparing a metallic pad sheet having a thickness equal to that of the paddle (22), and then dividing it into a multiplicity of pieces, each of the pieces having a contour such that the piece is suitable for use as the paddle (22).

Abstract: A field effect transistor includes a III-V compound semiconductor substrate (1) having a surface, III-V compound semiconductor layers successively disposed on said surface, including, from below, an InAlAs layer (5), an InP layer (6), and an InGaAs layer (7), a gate recess penetrating through the InGaAs layer (7) and the InP layer (6), and a gate electrode (8) in contact with the InAlAs layer (5). In this structure, the contact surface of the gate electrode (8) with the InAlAs layer (5) is on the same level with the interface between the InP layer (6) and the InAlAs layer (5). In producing the gate recess, the InGaAs layer (7) is first etched by an etchant comprising hydrogen peroxide water and at least one of tartaric acid, phosphoric acid, and sulfuric acid, using the InP layer (6) as an etching stopper layer, and then the InP layer (6) is etched by hydrochloric acid, using the InAlAs layer (5) as an etching stopper layer. Therefore, the depth of the gate recess is accurately determined by the etching stopper layers, resulting in field effect transistors with uniform electric characteristics.

IPC: G01S5/10

Abstract: Disclosed is a system for marking a plurality of zones within a cellular service area. A plurality of marker transmitters disposed throughout a cellular area transmit a zone identification signal to a mobile or portable cellular receiver. Each zone identification signal is transmitted in a radio frequency coverage area that is substantially coincident with the boundary of a zone. The mobile unit attempts to receive the zone identification signal in order to determine whether it is in the zone. If the mobile unit has determined it is in a zone, it transmits a signal on a reverse control channel to a cell site transceiver that in turn transmits a signal to a mobile telephone switching office. The mobile telephone switching office then can adjust the rate charged on a telephone call made by a user of the mobile unit based on the unit's location within the zone. The marker transmitters are programmed to transmit the zone identification signal during a predefined time slot so that more than one marker transmitter may simultaneously transmit the zone identification signal, thereby increasing the area in which the zone identification signal can be received by the mobile unit. In order to reduce the area in which a zone identification signal may be received by a mobile unit, the marker transmitters may transmit a jamming signal at the same time as the zone identification signal is transmitted.

Abstract: A field effect transistor, either with or without a lightly doped N- drain, incorporates a relatively conductive deep P body contact source plug to reduce parasitic resistance underneath an N+ source region and to prevent a parasitic bipolar transistor from latching on when the voltage between the drain electrode and the P well changes rapidly. In a lightly doped drain an N+ source region extends into a P well from an upper surface of the P well and a N- drain region extends into the P well so that the N+ source region and the N- drain region are separated by a channel region. An N+ drain contact region extends into the lightly doped N- drain region to a depth less than the depth of the N- drain region so that a portion of the N- drain region separates the N+ drain contact region from the channel and from the underlying P well. A deep P body contact source plug region extends into the P well at a location underneath the source electrode so that the deep P body contact source plug region extends toward the channel region at least partly underneath the N+ source region. A gate insulating layer is disposed on the upper surface of the substrate over the channel region and a gate is disposed over the insulating layer so that the gate overlies the channel region.

Abstract: An optical head device uses a birefringent diffraction grating polarizer configured in a reflection type. The device includes a polarizing hologram element (216) which reflects the light from a light source (210) to a converging lens system and diffracts the polarized light returning from a recording medium. A total reflection film (203) is formed on a surface of a diffraction grating which is provided periodically by an ion exchange region and a dielectric film on a surface of a crystal plate (200) having optically anisotropic characteristics. A polarizing beam splitter film (218) formed on a surface of the polarizing hologram element has reflectivity and transmissivity having dependency on the polarization of the incident light. In another form, a polarizing hologram element includes a polarizing hologram which has diffractive efficiency having dependency on polarization of incident light and a polarizing beam splitter film (218) which has reflectivity and transmissivity having dependency on the polarization of the incident light. The diffracted light is received by multi-split photodetectors. The arrangements enable to make the optical head device compact, light in weight and low cost.
