Abstract: Provided is a signal transfer circuit which uses a low cost circuit board with a high packing density but is capable of reducing a crosstalk noise between signal lines and also reducing a reflection noise due to a stub. A signal transfer circuit of the present invention is configured such that lead terminals of electronic components and through-hole vias are connected to each other by surface wirings, respectively, to allow no branching from the middle of the through-hole vias. Further, first wirings connecting a first electronic component are each arranged between a corresponding pair of second wirings connecting a second electronic component, and signals are transmitted through the first wirings and the second wirings by interleaved transmission.

Abstract: A slew rate of a signal transmitted between a semiconductor device having a small load capacitance and a semiconductor device having a large load capacitance is improved. When a signal is transmitted to the semiconductor device (for example, a memory device) having the large load capacitance, pre-emphasis is performed, and when a signal is transmitted to the semiconductor device (for example, a memory controller) having the small load capacitance, pre-emphasis is not performed or is slightly performed. By this, when the signal is transmitted to the memory device, blunting in signal rising due to the load capacitance is suppressed, and when the signal is transmitted to the memory controller, ringing due to the reflection of the signal is suppressed, and the slew rate of the data transmission is improved.

Abstract: An interposer to be mounted with an integrated circuit to be a test object is provided with a switch and a probe to detect an electric current corresponding to individual terminals of the integrated circuit. A test pattern signal is then inputted to the integrated circuit through a test substrate as a switch that is connected to a power supply terminal of the integrated circuit and that is turned off. If the integrated circuit normally operates and the current values of all the terminals of the integrated circuit are within a tolerance, the power supply terminal connected to the turned-off switch is identified as a terminal that may be removed.

Abstract: A vehicle heating and air conditioning system basically includes an interior/exterior air introducing structure, a heating device, a driving end time acquiring section and an interior/exterior air switching control section. The interior/exterior air introducing structure switches the flow of cabin intake air between an interior air recirculation mode and an exterior air introducing mode. The heating device heats the cabin intake air being introduced by the interior/exterior air introducing structure. The driving end time acquiring section estimates a driving end time corresponding to a point in time at which driving of a vehicle is predicted to end. The interior/exterior air switching control section switches the interior/exterior air introducing structure from the exterior air introducing mode to the interior air recirculation mode during a period of time from a prescribed point in time until the driving end time to restrict windshield fogging while in the interior air recirculation mode.

Abstract: In a prior art, there has been a method in which a power supply line of an output buffer and that of a control circuit are independently provided so that the power supply noise occurring in the control circuit will not affect the output buffer. However, this method has had the problems that it increases both the number of power supply/grounding pins and power feed line inductance.The present invention provides a technique which, without causing the above two problems, i.e., (1) increased number of power supply/grounding pins and (2) increased power feed line inductance, prevents the noise causing a problem in a control circuit, from becoming routed around and induced into an output buffer. More specifically, the above can be realized by using either of two methods: (A) providing an on-chip bypass capacitor for the control circuit and isolating a power feed route of the control circuit from that of the output buffer in an AC-like manner, or (B) designing electrical parameters (inserting resistors) such that the oscillation mode of any electrical parameter noise induced into the power feed routes will change to overdamping.
