Title: Foam-insulated electric wire
Inventor: HASHIMOTO MASARU
IPC: H01B3/30
Filed: 1991-05-14
Abstract: PURPOSE:To effectively use a foam-insulated electric wire for the high-speed signal transmission path of a computer by forming a fluorine foam body and a resin outer layer on the outer periphery of a conducting wire by extrusion coating to satisfy the signal propagation delay time required for a high-speed transmission cable and attain nearly the same characteristic as a conventional one. CONSTITUTION:Fluororesin containing a foaming agent is extrusion-foamed on the outer periphery of a twisted conducting wire (with the diameter 180mm in this case) twisted with seven strands 1a (with the diameter 0.064mm, for example) to form a fluororesin foam body 2 (with the outer diameter 0.61mm) with the expansion ratio 3.4, for example. The resin with the tensile strength per unit length weight 500kg/cm or above is extrusion-coated on the outer periphery of the foam body 2 to form a resin outer layer 3 with the thickness 0.010-0.050mm. A foam-insulated electric wire thus formed satisfies the signal propagation time required for a high-speed transmission cable, and its characteristic is nearly the same as that of a conventional one. It can be effectively used for the high-speed signal transmission path of a computer.

Filed: 1987-05-02
Abstract: PURPOSE:To obtain an expanded output with a desired nonlinear characteristic even with an input signal with a low level by constituting the titled circuit of a differential amplifier receiving an input signal, a lead/lag filter, an inverse amplifier and a couple of diodes of anti-parallel connection. CONSTITUTION:An input signal is given to a differential amplifier section 22 and an inverse amplifier section 27 and a prescribed level/frequency characteristic is given to an output signal of the amplifier section 27 by lead/lag filters 30, 33 and the result is fed to the input of the amplifier section 22 through a diode circuit 40. Thus, a level over a prescribed level at a prescribed frequency component selected by a filter section among an amplifier output signal of the amplification section 27 is fed in opposite phase with respect to the input signal to an input terminal of he amplifier section 22. Thus, the level of a portion of an output signal of the amplifier section 22 having a prescribed level or over in a predetermined frequency component in the input signal is expanded. Since the input signal is applied to the circuit 40 while being amplified, even if the input signal level is small, the circuit is operated normally.

Abstract: PURPOSE:To automatically detect abnormality of a stack operation by providing a stack error detecting circuit on a CPU. CONSTITUTION:At the time of popping the data for showing the push data length from a RAM 7, a control part 5 outputs simultaneously a pop signal 18 and a lead signal 11, and leads 1 byte data for showing the push data length to an address/data bus 3 from the RAM 7. A stack error detecting circuit 100 inputs a push signal 16, an L signal 17 and the signal 18 from the control part 5, compares the number of data bytes of pushed data and the number of bytes of data to be popped, regards it as an error only when the number of both the bytes is different, and outputs a stack error detecting signal 28. Subsequently, after a pop instruction is executed, the circuit 100 allows a CPU 31 to execute a suitable error processing. On the other hand, in the case the signal 28 is not outputted, a stack operation is regarded as normal, no error processing is executed, and the circuit 100 executes the next instruction.
