Title: Preamble detection circuit
Inventor: SERIZAWA MUTSUMI
IPC: H04L7/10
Filed: 1986-06-26
Abstract: PURPOSE:To detect a top signal pattern in a preamble from an input signal at high accuracy by providing a 1st band pass filter including a frequency component in its pass band and a 2nd band pass filter excluding a frequency component in its pass band. CONSTITUTION:The BPF 1 has a pass band characteristic with its nonmodulation carrier frequency as a center, and the BPF 2 has the characteristic of a pass band in the vicinity of the nonmodulation carrier frequency excluding said nonmodulation carrier band. When signals of a channel including the BPFs 1 and 2 arrive in a burstlike shape, the signal passing through the BPF 1 includes a preample signal at a nonmodualtion carrier frequency. Since the pass band of the BPF 2 excludes the nonmodulation carrier frequency, the signal passing through the BPF 2 is constant according as the preamble signal is received or not. Out of two powers inputted to a comparator circuit 7 through power calculation circuits 3 and 4 and LPFs 5 and 6, the power passing through the BPF l increases, and an output from the comparator circuit 7 exceeds a reference value. Finally a preamble detection signal is outputted from a detection circuit.

Filed: 1988-06-17
Abstract: PURPOSE:To efficiently form a nitride layer having excellent wear resistance and good adhesive property on the surface of an Al material by roughening the surface of a material to be treated in a gaseous mixture atmosphere composed of a gas contg. O, N, C and a rare gas, then subjecting the surface to an ion nitriding treatment. CONSTITUTION:The Al material 3 is disposed on a base plate 2 in a hermetic vessel 1 and the residual oxygen in the vessel 1 is removed by evacuating the inside thereof to a reduced pressure by a vacuum pump 8. A gas for heating up such as gaseous hydrogen is run in the vessel and a DC voltage is impressed between an anode plate 12 and a cathode (base plate 2) to heat up the gas. The gaseous mixture composed of 5-2,000ppm gas contg. at least >=1 kinds of the elements of O, N, C and rare gas such as Ar is then introduced as the gas for the surface roughening treatment into the vessel and the surface of the Al material 3 is roughened by a glow discharge or ion beam. The gas for the nitriding treatment is introduced into the vessel and the ion nitriding is effect under glow discharge to form the nitride layer. The time for the surface roughening treatment is shortened in this way and the uniform nitride layer is formed.

IPC: H01L27/10
Filed: 1986-06-27
Abstract: PURPOSE:To make it possible to decrease soft errors to a large extent without increasing the threshold voltage value of a peripheral circuit, by using a field- inversion preventing diffusing layer beneath an element isolating insulation film surrounding a trench as a diffusing source, and forming an impurity diffused region having the same conductivity type as that of a semiconductor substrate on the semiconductor substrate at the bottom part of the trench. CONSTITUTION:On a P-type semiconductor substrate 15, a thermal oxide film 16 and an Si3N4 film of silicon nitride are formed. Thereafter, a resist pattern 18 is formed on an element region. With the pattern as a mask, the Si3N4 film 17 is etched. Thereafter, with the resist pattern 18 and the Si3N4 film 17 as masks, boron ions are implanted. The resist pattern 18 is separated and heat treatment is performed. Thus P-type well regions 191 and 192 are formed. Then the Si3N4 film 17 is used as a mask for selective oxidation, and thermal oxidation is performed. After field oxide film 202 and 202 are formed, only the Si3N4 film 17 is etched away. Since the element region is narrow at a memory cell part, the well regions 191 and 192 are contacted by the diffusion of borons in the lateral direction. A shallow impurity diffused region 21 is formed in the element region at the memory cell part.
