摘要:
An input processing circuit is interposed between input terminals and input ports of an MPU. An output processing circuit is interposed between output ports of the MPU and output terminals. The input processing circuit includes switch sections and processing sections. The output processing circuit includes switch sections and processing sections. A switch control section switches the switch sections based on switch information stored in a switch information storage section to switch a connection relationship between the input terminals and the input ports, processing for an input signal, a connection relationship between the output ports and the output terminals, and processing for an output signal.

The present invention relates to an improvement of a packaging material for use in integrated circuits (IC) such as IC, LSI and VLSI, and in particular to an improvement of a lead frame made of iron-nickel alloys used as a material in a low-melting-point glass-ceramic package. The invention resides in provision of a lead frame faces made of an iron-nickel alloy substrate containing nickel therein at a ratio of 42 to 49% by weight and the improvement wherein an aluminium layer of 0.2 to 10 microns thick is coated on both faces and sides of the substrate.

The invention provides a process for preparing a refractory molded article and a binder with advantages such as casting of a molten metal without generation of gases and prevention of such defects as blow holes, good flow of a molten metal enabling thin-wall casting of steel, reduced requirement of riser in steel casting compared with cold casting, good dimensional precision, wide applicability to materials ranging from light alloy to steel, and an inner part for adjustment of strength and improvement of crumbling characteristics.
摘要:
Dilute standard gases are prepared by utilizing a buffered solution of a compound capable of generating a desired gas. The pH of the solution adjusted so as to provide a solution with a desired specific vapor pressure of said gas and said gas is absorbed by a flow of air passed through the vapor phase above the solution. An apparatus for the performance of said process is also provided.

An image shooting unit is installed on a vehicle and shoots an image of an area around the vehicle at a set frame rate. A recognizing unit performs image recognition on the image to check whether an object is present in the image. A frame rate setting unit increases the frame rate in the image shooting unit when an object is present in the image so that more images are acquired per unit time.
