Abstract: The present invention is a polyamide resin composition which contains 50 to 90% by mass of a crystalline polyamide resin (A) and 9 to 49% by mass of a talc (B). The average particle size of secondary particles of the talc (B) in the polyamide resin composition is 30 ?m or less. The polyamide resin composition has an exothermic peak present on a high temperature side of a maximum exothermic peak of a crystallization temperature during cooling in a cooling process of measurement by means of a differential scanning calorimeter. Variations in physical characteristics such as a molding shrinkage, mechanical characteristics, and a heat distortion temperature of the polyamide resin composition are suppressed among different production machines or different production lots. Consequently, characteristics within desired ranges are stably obtained.

Abstract: A film forming method selectively performs film formation. The film forming method includes a cooling operation and a film forming operation. The cooling operation includes cooling a substrate to a temperature at which molecules of a c-C4F8 gas and a SF6 gas condense on a surface of the substrate, the substrate having a metal film and a first insulating film exposed on the surface and being supported inside a chamber. The film forming operation includes forming a carbon-containing film on the metal film by supplying a processing gas including the c-C4F8 gas and the SF6 gas into the chamber while exciting the surface of the substrate.

Abstract: In a semiconductor integrated circuit provided with a circuit for testing an input buffer threshold voltage, an output node of a first logic gate having its output logic value determined by an output signal of an input buffer, and an output node of a second logic gate having its output logic value determined by a condition setting signal from an external source, are connected to a common signal line. When a standardized voltage for discriminating the threshold voltage is applied to the input buffer, if the input buffer malfunctions, the output signal of the first logic gate collides with the output signal of the second logic gate on the common signal line, so that a power supply current greatly increases.

Abstract: A serial-parallel converter is arranged to convert an information sequence into a plurality of bit sequences. Two convolutional encoders are provided which respectively receive bit sequences from the serial-parallel converter. Each of the two convolutional encoders outputs first and second bit sequences. First parallel-serial converter receives the first bit sequences and converts them into third bit sequence, while second parallel-serial converter receives the second bit sequences and converts them into fourth bit sequence. The third and fourth bit sequences are used to modulate two carriers with a phase difference of .pi./2 radians.

Abstract: In a simple decoder which decodes convolutional codes of constraint length K and coding rate n/m, encoded data which is supplied thereto in steps of m bits are distributed, bit by bit, to m shift registers each having x=[(K-1)/(m-n)] series-connected shift stages. Here, [p] means the minimum integer equal to or larger than a real number p. The connection of n modulo-2 addition circuits to all the shift stages of all the shift registers is defined by n decoding generative vectors which define n decoding generative polynomials. The modulo-2 addition circuits perform modulo-2 additions of the outputs of the shift stages connected thereto and output n results of additions as decoded results of n bits. The n decoding generative vectors are selected from decoding generative vectors of N rows which are obtained as an inverse matrix of a square matrix whose elements are N.times.N coefficients which define N=mx convolutional code generating polynomials.
