Title: Method of judging mark for semiconductor device
Inventor: SANO TETSUYA
IPC: H01L23/00
Filed: 1981-08-31
Abstract: PURPOSE:To judge marks to be good or bad and to recognize letters and symbols easily, correctly and quickly by comparing a mark to be judged with each of the reference classfied marks to pass judgment based on the difference between them. CONSTITUTION:Images of letters B, G, V for classifying the colors of products are picked up and divided into roughly 20X28 picture elements. Among these letters, the one marked in the best condition is converted into a binary value and treated as a reference pattern. Subsequently, the image of a letter necessary to be classified is picked up and converted into a binary value. By making P(i,j), X(i,j) represent the above binary components, respectively, the correlative function (r) is computed. If the difference between the largest function and the one next to the largest is larger than a certain reference value, that correlative function will be regarded as the one representative of a letter of the largest type; moreover, the correlative function indicating a value greater than a preset reference one for judgment is estimated to represent a good product.

Title: Air flow rate measuring apparatus
Inventor: OZAWA MASAYUKI
IPC: G01F1/68
Filed: 1994-06-20
Abstract: PURPOSE:To keep measurement precision by making the outside wall shape of an auxiliary air route asymmetric on the center axis of the auxiliary air route and avoiding the expansion of a flow separated part due to counter flow to the upper face of the inlet of the auxiliary air route. CONSTITUTION:A heating resistor 4 to detect air flow rate and a heat sensitive resistor 5 to detect sucked air temperature are installed in the inside of a main air flow route 1 and in an auxiliary air route 2, respectively, The auxiliary air route 2 is made so as to have an asymmetric shape on its center axis. When counter flow occurs in the main air route 1, since the outer wall of the auxiliary air route 2 is asymmetric, pressure distribution becomes uneven due to the separated part formed in the outer wall part. Consequently, since flow direction of the counter flow is curved and the separated part formed in the outer wall of the auxiliary air route 2 is shifted to the wall face direction of the main air route 1 in the upper stream of the inlet of the auxiliary air route 2, the difference of the pressure in the outlet and in the inlet of the auxiliary air route 2 becomes small as compared with that in the case the separated part is in the upper stream side of the inlet of auxiliary air route 2. As a result, counter flow is lessened and measurement error due to the counter flow can be lessened.

Abstract: PURPOSE:To generate a strong turbulence within a combustion chamber upon running at a low-load and secure a high filling efficiency upon running at high speed and high load by providing an opening and closing control valve in a window communicating both inlet passages with each other, in the internal-combustion engine having two inlet passages in each cylinder. CONSTITUTION:Each cylinder of an internal-combustion engine is composed of a first inlet passage 12 having a first inlet valve 3 and a second inlet passage 13 having a second inlet valve 4. An opening and closing control valve 15 is provided at a window 14 communicating both passages 12 and 13 with each other. When the engine is driven at a low speed, the window 14 opens and sucked air within the second inlet passage 13 is deflected A therefrom toward the first inlet passage, and sucked air only from the first inlet port 12 is supplied. In this manner, a turning flow B is generated within the combustion chamber 2 and the combustion efficiency is improved. Hence, the fuel consumption rate can be improved. When the engine is driven at a high speed, the window 14 is closed, no obstacles exist in the inlet passages 12 and 13, and the flow resistance becomes small. Therefore, a high filling efficiency can be secured and a high output can be obtained.
