Abstract: A semiconductor storage device includes: a semiconductor substrate; a plurality of circuit regions; and an element isolation region having a trench shape formed between the circuit regions. In the element isolation region including a thermal oxide film and a silicon oxide film, a sub-trench is formed in a bottom corner portion, and the thermal oxide film covers at least an inner wall of the sub-trench.

Abstract: This electronic component is provided with an inorganic substrate, a conductor film formed on a surface of the substrate, and bonding wires bonded to a part of said conductor film, and wire bonding sections are formed on at least a part of the electronic component. The part of the conductor film at least forming the aforementioned wire bonding sections contains an Ag-based metal formed of Ag or an alloy having Ag as the main constituent and a metal oxide which coats said Ag-based metal and which has, as a constituent element, any of the elements selected from the group consisting of Al, Zr, Ti, Y, Ca, Mg, and Zn. The coating quantity of the metal oxide is a quantity corresponding to 0.02 to 0.1 parts by mass relative to 100 parts by mass of the aforementioned Ag-based metal.

Abstract: A radar apparatus in which an interpolated sweep between adjacent real sweeps is formed irrespective of an interval between the real sweeps, and image data corresponding to one cycle of sweeping can be certainly updated. A sweep azimuth generator (12) generates and outputs an azimuth of sweep interpolated between a current and previous real sweep azimuth based on the current and previous real sweep azimuths, to a draw address generator (7). A sweep data generator (11) performs linear interpolation based on solitariness removed data of current real sweep data read from a sweep memory (4), and the previous solitariness removed real sweep data stored therein to generate and output interpolated sweep data to an image memory (8). The image memory (8) stores the solitariness removed real sweep data or the interpolated sweep data based on the real and interpolated sweep azimuths from the draw address generator (7), and outputs them to a display (9).

Abstract: There is configured a radar or similar device that outputs received data that is currently being received and scan correlated image data in parallel with each other. Scan correlated image data and display image data resulting from received data from a display video memory 13 are input into a transitional data generator 11, and the transitional data generator 11 generates transitional data that represents an intermediate value and gradually changes from the received data into the scan correlated image data, using these signals, and inputs the transitional data into a selector 12. The received data, a FIRST or a LAST signal, and the transitional data are input into the selector 12, and the selector 12 outputs the received data if FIRST=1, and outputs the transitional data if FIRST=0, to the display video memory 13. This image data is fed back to the transitional data generator 11, and therefore it gradually changes from the received data into the scan correlated image data.

Abstract: A radar device is provided that can reliably display sensed image data of an object, regardless of the state of the object (echo) within a sensed range and of the surrounding environment. A behavior data detector 11 generates current level detection data by detecting a level behavior of sensed image data X(n) handled by a W data generator 7 from sensed data x(n) that is output from a sweep memory 4. Previous behavior data constituted by level detection data of several past scans is stored in a behavior data memory 12, and the behavior detector 11 updates the previous behavior data with the current level detection data and outputs the result to the W data generator 7. Detecting characteristics of the sensed image data of corresponding pixels from the behavior data, the W data generator 7 selects filter calculation data W(n), the current sensed image data X(n) or specific filter calculation data Z(n) and outputs the selected result as written image data Y(n).

Abstract: When resin pipes are connected through induction heating, the resin pipes of this invention do not form inside bulges due to air and resin expansion during the heating process. A cylindrical heater made of stainless steel is placed around the joint between two resin pipes made of polyvinylidene fluoride. The heater is then heated by induction heating to weld the joint of resin pipes. The heater has a plurality of holes on the cylindrical surface so that air and molten resin located between the heater and the resin pipes are released through the holes.
