Title: Control method for air-fuel ratio
Inventor: HARA KAZUO
IPC: F02D41/14
Filed: 1987-01-21
Abstract: PURPOSE:To prevent air-fuel ratio from changing suddenly by obtaining a lambdavalue by adding or subtracting a convergence  lambda value (air-fuel ratio control factor) stored at every specified time cycle when an O2 sensor is determined to be inactive, and switching to an open loop control when the value has converged to a basic value. CONSTITUTION:Calculating a basic pulse width Ti with a calculating means 11 according to output signals from an air flow meter 2, an rpm sensor 3 and a water temperature sensor 4, a fuel injection pulse width To is obtained by making a multiplying means 18 multiply the basic pulse width Ti by a lambda value determined with a lambda value calculating means 13. The lambda value calculation means 13 is arranged to calculate the lambda value according to the decision result of an activeness decision means 12 for determining active/inactive condition of an O2 sensor 1. Namely when the sensor is determined to be inactive, the lambda value at that time is compared with a basic value (e.g. lambda=1). If lambda>1(lambda<1), a constant value ALPHAlambda stored in a memory means 17 in advance is added (subtracted) to make the value converge to lambda=1. When lambda=1, control is switched to open loop.

Title: Semiconductor storage device
Inventor: MIURA ATSUSHI
IPC: H01L21/82
Filed: 1991-02-01
Abstract: PURPOSE:To obtain a semiconductor storage device, in which the generation of an error of cutting of fuses due to an alignment deviation to either one of direction X and Y can be prevented, by a method wherein a multitude of the fuses for redundancy correction programming use are arranged in such a way that the arrangement direction of the fuses is set in one direction. CONSTITUTION:In a DRAM, the alignment deviation (a deviation from the position of a design) of fuses 3 is frequently generated. However, as all the fuses are arranged in a direction X, the cutting positions of the fuses are merely deviated by an amount in the direction X and as the cutting itself of the fuses is properly performed, an error of the cutting is not generated and the improvement of the yield of the fuses is achieved. As the rows of these fuses are arranged in a body in one direction, an alignment margin is not only generated but also even in a case a large alignment deviation exceeding this margin is generated, the discovery of a cutting failure by a visidual observation can be easily made and the supply of defectives to a market can be prevented.

Title: Junction by high-temperature superconductor
Inventor: AWAJI NAOKI
IPC: C04B37/00
Filed: 1989-01-24
Abstract: PURPOSE:To prepare a tunnel junction, both sides of which are composed of high-temperature superconductive materials, stably without leakage by forming an insulating layer to the hetero-junction section of dissimilar ceramic superconductive materials through a mutual diffusion on junction surfaces in a process in which the hetero-junction is shaped. CONSTITUTION:In a process in which the hetero-junction of dissimilar coramic superconductive materials 12, 14 is formed, an insulating layer is shaped to the junction section 13 through a mutual diffusion on junction surfaces. Two kinds of ceramic superconductive materials 12,14 having different composition elements such as a Y-Ba-Cu-O group superconductive thin-film and a Bi-Sr-Ca- Cu-O group superconductive thin-film are laminated onto a substrate 11 consisting of the MgO single crystal of (100), the SrTiO3 single crystal of (100) or (110) or the like. The substrate 11 is heated at the temperature of crystallization at that time, and the different composition elements mutually diffuse by the heat (approximately 600 deg.C or higher) of the substrate. Accordingly, superconductivity is lost due to displacement from a stoichiometric ratio of a composition or the difference of the lattice constants of crystals in the junction section 13, thus forming the insulating layer.

Title: Method for treating output signal of semiconductor bio sensor
Inventor: KANEYOSHI AKIO
IPC: G01N27/414
Filed: 1991-02-04
Abstract: PURPOSE:To enable a measurement time to be reduced by performing filter processing of an output signal of a sensor, detecting a peak of a differential value in sequence, obtaining an intermediate value and performing approximation by a polygonal line, and by determining a concentration of a substrate to be measured. CONSTITUTION:An output of a semiconductor bio-sensor is A/D converted, is inputted as a digital signal, is processed by a digital filter, and noise components are eliminated. A difference with a previous data which is inputted is calculated and a differential value is calculated and then it is examined whether a differential waveform immediately before this differential value is obtained is in increase or decrease tendency. In the case of the increase tendency, when an immediately previous differential value is larger than a most recent differential value, the previous differential value becomes a peak value at the time of increase. On the other hand, when the immediately previous differential value is smaller than the most recent differential value, the immediately previous differential value becomes a peak value at the time of increase. On the contrary, when the immediately previous differential value is smaller than the most recent differential value, the immediately previous differential value is detected as a peak at the time of decrease so that an average value between the peak which is detected last time and the most recent peak becomes an approximation value indicating an entire change of a differential waveform. When the approximation value of the last time becomes smaller than the most recent approximation value, the approximation value of the last time becomes a first peak of the approximation by a polygonal line and this value is proportional to a concentration of a substrate to be measured.
