摘要:
To provide a testing apparatus having a function of testing a D/A converter and so forth with a reduced testing time. The testing apparatus tests a converter having functionality of converting an input signal and outputting the signal thus converted. The testing apparatus comprises: a pattern generator which generates an input signal having a predetermined cycle; a clock generator which generates a measurement clock having a predetermined cycle; a measurement unit which receives the measurement clock, and sequentially measures the values of the output signal, synchronously with the measurement clock; and a storage unit which stores, at different corresponding addresses, the values thus sequentially measured by the measurement unit.

An apparatus for bending a glass sheet includes a final hearth bed. This final hearth bed has a top surface that is upwardly convexly curved along a plane perpendicular to an axis of the glass sheet. The top surface has an upstream end, a downstream end that is at a level lower than that of the upstream end, and an intermediate point defined therebetween. The top surface has (a) a first section that extends from the upstream end to the intermediate point and that is parallel with the axis or upwardly inclined relative to the axis and (b) a second section that extends from the intermediate point to the downstream end and that is downwardly inclined relative to the axis. The final hearth bed has a bottom surface that is along the first direction or inclined downwardly relative to the first direction.

For bending a glass sheet so that the glass sheet has a compound curvature, an apparatus comprises a furnace including hearth beds on a bed support and a quenching unit provided with upper and lower air blowers. The final hearth bed may have a top surface with a simple curvature, be provided with one upstream corner cut away thereby defining a cut surface section and arranged in such a manner that the cut surface section is nearly parallel to the hearth bed adjacent to the final hearth bed. Alternatively, the final hearth bed may have a top surface with a compound curvature, so that the glass sheet is bent under the conditions set by controlling a temperature in a downstream part of the furnace, adjusting the inclination of the lower air blower and/or rotating final hearth bed so as to reverse the upstream and downstream ends thereof.

A film inspecting apparatus is used for inspecting fine roughness and particle state on a surface of a thin film. In inspecting the thin film surface, shape data of the thin film are obtained by a scanning type probe microscope. The obtained shape data are analyzed to identify individual particles, and the fine roughness and particle state on the thin film surface are inspected based on the particle data obtained by the shape data analysis. The film inspecting apparatus includes a particle analyzing device for inspecting the fine roughness and particle state on the thin film surface by using the shape data obtained by the scanning type probe microscope. The particle analyzing device includes a particle extracting device for extracting the particles on the film surface from the shape data, and a particle data calculating device for calculating the particle data based on the data extracted by the particle extracting device.

A semiconductor device including a register bank circuit includes a register array for storing data. The register array has a matrix structure which is formed of a plurality of banks arranged in a row of the matrix structure and a plurality of registers arranged in a column thereof. A bank selector selects one of the banks while the one to be selected is specified. A register selector selects one of the registers in the one bank selected by the bank selector means, so that the selected register is coupled to a bus.

An improved epoxy molding composition for encapsulating microelectronic devices wherein the molding composition, after conversion to a thermoset condition, i.e., infusible state, by the application of heat and pressure, displays a low coefficient of thermal expansion and a high thermal conductivity. The dual properties of low coefficient of thermal expansion and high thermal conductivity are imparted to the molding composition by the incorporation therein of a specific anisotropic, polycrystalline, sintered ceramic product which is relatively non-abrasive and free of ionic contaminants and which has cordierite as its primary phase, consisting essentially on an analytical oxide basis of 11.5 to 16.5% RO, 33 to 41% Al.sub.2 O.sub.3 and 46.6 to 53% SiO.sub.2.

摘要:
A Fenton reaction catalyst including a reaction product as an active component, in which the reaction product is obtained by using roasted and ground coffee beans (in particular, coffee grounds) or tea leaves (in particular, tea dregs) as feedstocks for supplying a component having a reduction effect, and mixing the feedstocks for supplying the component having a reduction effect with an iron-supplying source containing divalent or trivalent iron in the presence of water. The Fenton reaction catalyst can be used to generate hydroxy radicals from hydrogen peroxide. The Fenton reaction catalyst can maintain iron in a divalent state for a long period of time.

According to one embodiment, in the angle detection apparatus, the first A-D converter unit receives the first signal, and performs analog-to-digital conversion of the first signal. The second A-D converter unit receives the second signal orthogonal to the first signal, and performs analog-to-digital conversion of the second signal. The first delay circuit receives a third signal outputted by the first A-D converter unit, and performs a phase adjustment of the third signal. The second delay circuit receives a fourth signal outputted by the second A-D converter unit, and performs a phase adjustment of the fourth signal. The phase detection adjustment unit monitors phases of signals outputted by the first and second delay circuits, and gives phase adjustment commands to the first and second delay circuits, when a phase shift occurs.
