Title: Semiconductor wafer
Inventor: TOIKAWA SHIGERU
IPC: H01L29/788
Filed: 1987-07-01
Abstract: PURPOSE:To realize a markingless, to shorten steps, and to efficiently deliver data surely to ensuing steps by forming a memory cell capable of recording data on result of a wafer test and various types of information on a manufacturing device together with a plurality of chips in the same wafer. CONSTITUTION:When all chips in one wafer are completely measured in step S3, in step S4, data of test result of the wafer stored in a memory of an IC tester or a wafer probe is transferred together with various types of information on, such as lot No. and the like through a probe used for the test or a probe prepared separately to a nonvolatile memory cell 6 of the wafer 1. A time required for this transfer may be much shorter than a writing time in a recording medium. When necessary number of wafers are completed in this manner, the wafer is fed to the ensuing step in step S6. A device of the following step may transfer the various types of information of the wafer from the nonvolatile memory cell in the wafer through the probe to its own memory. Thus, the result of the wafer test and the various types of information can be recorded 1:1 to the wafer, a markingless is realized, and the steps can be shortened.

Title: Control method for internal combustion engine
Inventor: OKABE TAKESHI
IPC: F02D45/00
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To reduce NOx contents in exhaust gas by operating at least one of air-fuel ratio, ignition timing, swirl ratio, EGR factor, valve timing, and coolant temperature. SOLUTION: In a relation of combustion variation and NOx amount in exhaust gas with air excess factor (air-fuel ratio), solid curved lines show a case of high atmosphere temperature, or a case of low absolute humidity, and a case of meeting these two conditions. Dashed curved lines show a case of low atmosphere temperature, or a case of high absolute humidity, and a case of meeting these two conditions, and when the air-fuel ratio becomes higher both for solid lines and dashed lines, the NOx amount becomes lower and the combustion variation becomes larger. For the dashed lines, the combustion variation becomes larger and the NOx amount becomes lower, on the contrary, when the atmosphere temperature is high, reverse situations are provided.  Because the NOx amount for the combustion variation is almost constant, operation at the air-fuel ratio for making the combustion variation constant can control the NOx amount constant.

Title: Buffer using dynamic threshold value mos transistor
Inventor: HIRANO YUICHI
IPC: H03K19/017
Filed: 1998-06-11
Abstract: PROBLEM TO BE SOLVED: To save power consumption in a buffer using a dynamic threshold value MOS transistor. SOLUTION: Delay exists between the change of an input signal S1 and that of the output signal S3 of an inverter 11. Therefore, when the input signal S1 is low at present and is supposed to be shifted to high, the change of the input signal S1 from low to high is transmitted to a body for a while. Then, a threshold value is reduced since a body potential is hightened and a time till the transistor N1 is turned on is shorteneed. When the output signal S3 perfectly becomes High, the transistor P2 is turned off and the input signal S1 is not transmitted to the body. At the same time, the transistor N2 is turned on so that the body potential is grounded and surely becomes low. Therefore, the threshold value of the transistor N1 returned to be high, a current is prevented from flowing from the body to a source and power consumption is saved.

IPC: G01B21/00
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To provide an accurate position measuring method in which measurement error of individual sensor is suppressed significantly. SOLUTION: Two measuring bars M1 , M2 comprising different regions are arranged on a support. Number of regions, and thereby the numbe of periods to be generated, is selected such that one measuring bar has (m) periods over the overall length L while the other measuring bar has (m+1) periods. Both measuring bars are scanned with respective sensors SE1, SE2. The sensors SE1, SE2 deliver specified signals depending on the position of the measuring bars M1 , M2 and these signals are evaluated by an evaluator according to a unique algorithm. The algorithm takes account of the relationship between two output signals from both sensors SE1, SE2 normalized to maximum values and the difference of period between two measuring bars thus determining a current position accurately.
