Patent JP-H0814083-A (JP)
Title: Electronic control device for internal combustion engine
Inventor: KONDO KATSUHIKO
IPC: F02M25/08
Filed: 1994-06-30
Abstract: PURPOSE:To perform accurate control of an air-fuel ratio in spite of the operation state of an internal combustion engine and an amount of vaporized fuel generated in a fuel tank by correcting a flow rate of purge air during ON of purge control according to the length of a pure control OFF period at least right before at least purge control ON. CONSTITUTION:A control device 22 is constituted to estimate an amount of vaporizing fuel adsorbed to a canister 18 in a purge control OFF period from the length of a purge control OFF-period right before at last purge control ON. Since, according to an amount of the vaporizing fuel, i.e., when an amount of vaporizing fuel in the canister 18 is high, purge air density is considered to be high, a flow rate of purge air is decreased. Since, when an amount of vaporizing fuel in the canister 18 is high, purge air density is considered to be low, a flow rate of purge air at a purge control ON-period is corrected so that a flow rate of urge air is increased. This constitution performs control in answer to purge air density and reduces an influence exercised on an air-fuel ratio.

Title: Ultrasonic signal processing device
Inventor: MASUZAWA YUTAKA
IPC: G01N29/44
Filed: 1993-06-22
Abstract: PURPOSE:To perform the highly precise digital phasing processing of an ultrasonic device at low cost. CONSTITUTION:A device is supplied with an input signal obtainable when a reflected wave having a central angle frequency omega reaches a receiver element having an element number (n) after the elapse of a propagation time taun. Then, when the standardized period of an input signal processing system is Ts and the time taun is quantized with Ts, the phases of the carriers are aligned with each other because of a phase difference due to the time taun among receiver elements, provided that the carriers or waves are made to travel along a time axis having a unit of Ts via delay circuits 11 to 1m. Then, for integrating the waveforms of all receiver elements, complex multipliers 21 to 2m are used to make correction for the phase terms of the carriers. Also, real and complex parts are added in adders 31 and 32, thereby enabling a filter circuit to be used in common via a plurality of input signals.

Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To provide a manufacturing method of a semiconductor device, capable of reducing crystal defects caused by an internal stress which is distinct to film nitride used in self-alignment, and to improve the production yield. SOLUTION: After laminating a film nitride 26 on an upper face of a thermal oxidation film 25 on a P-type layer 23 formed on an n-type silicon substrate 24, openings for emitter electrode connection are formed penetrating the film nitride 26 and the thermal oxidation film 25, and the upper face of the base layer 23 is exposed at the bottom of the opening. By filling up the opening for emitter electrode connection by a polycrystalline silicon layer which has an n-type impurity arsenic, an emitter lower electrode 32 is formed by etching, and an emitter layer 34 is formed through thermal diffusion of arsenic contained in the polycrystalline silicon layer into the base layer 23. An emitter electrode 38 is formed by forming an upper emitter electrode 36 composed of Al on the lower emitter electrode 32.  This structure cancels out the internal stress of the film nitride 26 and the polycrystalline silicon layer, and suppresses the internal stress in the silicon substrate 24.

Abstract: PROBLEM TO BE SOLVED: To reproduce the waveforms of short pulsed light with high accuracy. SOLUTION: By repeated measurement with an optical pulse analyzer, the fundamental optical interfering signal strength waveform data If (τ) and the secondary harmonics optical interfering signal strength ISH(τ) of short pulsed light are obtained and Fourier-transformed, and the fundamental electric field spectrum amplitude |E(ω)| and the secondary harmonics electric-field spectrum amplitude |U(ω)| are calculated. By using |E(ω)|, the value of a phase ψ(ω) is postulated, and a postulated electric field waveform e(t) is obtained. And the secondary harmonics electric-field waveform u(t) is obtained from the pustulated electric waveform e(t), and the calculation value |U'(ω)| of the secondary harmonics optoelectric spectrum amplitude is calculated. The calculated spectrum amplitude |U'(ω)| is standardized on the basis of a calculation value |U'(0)|and the measurement value |U(0)| at the time when ω=0. By repeating the minute changes of the phase ϕ(ω), the phase ϕ(ω) that minimizes the error of the calculation value and measurement value at the secondary harmonic electric-field spectrum, and the true electric field amplitude e(t) is determined.
