Title: Method for inspecting accuracy in overlapping for overlapping exposure
Inventor: FUJISAWA MINORU
IPC: G03F1/84
Filed: 1980-09-17
Abstract: PURPOSE:To simplify the accuracy inspection by exposing the first mark group which is linearly formed in the same size at the same pitch, then overlapping the second mark group which has the same pitch but the different size sequentially, and measuring the number of gaps between the formed marks. CONSTITUTION:On the specified parts of a material to be exposed, an opening pattern is formed by using mask 1, wherein a plurality of rectangular openings A1- A5 with e.g. a width L and an interval L are linearly provided, at the first exposure. Then, the overlapping exposure is performed by a mask 2, wherein openings B1-B5 with the widths of L+delta, L+2delta, ... L+5delta(therefore the intervals are L-delta,... L-4delta) are provided at the same pitch as the openings of the mask 1.  For example, in the case of L=5delta, if the accurate aligning is made at the left end of each opening, four gaps are formed in the figure formed by the overlapping. The number of gaps is decreased every time the overlapping errors increase as delta, 2delta.... By measuring the number of gaps, the accuracy in the overlapping exposure can be simply inspected.

Title: Plasma cutting method of spiral welded pipe
Inventor: FUKUSHIMA HISAFUMI
IPC: B23K10/00
Filed: 1983-07-14
Abstract: PURPOSE:To minimize generation of fumes by increasing an arc current value to the value optimum to the thickness of a spiral pipe only when a plasma-cutting torch passes through the weld seam part of the spiral pipe. CONSTITUTION:A timer T is provided to a driving source M of a flying cutter 4 and the time (t) until a cutting torch 6 intersects with a weld seam 3 where traveling starts is set to the timer T; at the same time, the timer T is so arranged that the signal therefrom is transmitted to an arc current regulator 10. The plasma arc current is increased up to the current value optimum for the thickness l+alpha of the weld seam 3 only during the time when the torch 6 passes through the seam 3 upon emission of the limit signal of the set time (t) from the timer T. Therefore, the torch 6 starts traveling and the plasma arc current value is automatically controlled at all times to the current value optimum for the thickness of a spiral pipe 5 until said torch finishes cutting the pipe.

Title: Position recognizer
Inventor: KOBAYASHI AKIRA
IPC: G06T7/00
Filed: 1989-05-23
Abstract: PURPOSE:To recognize the position of an apex with no influence received to the noises and cracks at the corners of a graphic by performing the detection of a contour line, the projection of a contour point, and the production of a contour point position frequency distribution after binarization of a picture and then performing the linear approximation. CONSTITUTION:A contour point projection circuit 12 projects the contour points forming a detected contour line onto the reference axes X and Y in each contour linedirection. A contour point presence frequency distribution production circuit 13 produces a presence distribution of positions of projected contour points for each reference axis. Then a linear approximation data extracting circuit 14 detects the position having the highest position distribution frequency for each produced contour point presence distribution and then extracts the data in a range of width + or -delta and around the detected position. Then the contour points showing the sides of an original graphic are extracted together with calculation of the equation of the straight lines of two sides set at both sides of an apex and the calculation of an intersecting point between two straight lines. Thus a desired apex is recognized. As a result, the resistance is increased to the noises and the cracks at the corners of a graphic.

Title: Arithmetic circuit for wheel turning speed
Inventor: ARIKAWA TETSUO
IPC: G01R23/10
Filed: 1980-09-18
Abstract: PURPOSE:To calculate a wheel speed almost instantaneously by a simple circuit by using two dividers, two counters, and an operating device in combination. CONSTITUTION:An operating device 4 is provided which outputs the digital value of a wheel speed on the basis of a wheel speed signal R generated by the signal of a wheel speed sensor 8. A divider 1 counts a high frequency f0 and, every time its count value reaches a certain value, generates one pulse. The pulse is counted by a counter 1 in a period relating to the period of the signal R. On receiving the count value through the operating device 4, a divider 5 counts the high frequency f0 and, every time its count value becomes equal to the output of the counter 1, generates one pulse. This pulse is counted by a counter 6 in the period of the signal R and the resulting count value is supplied to the operating device 4. When the count value of the counter 6 is not equal to a constant digital value, the output of the operating device 4 is corrected by its differnce. Thus, the simple circuit calculates the wheel speed almost instantaneously.

Title: Fuel injection amount controlling method of internal-combustion engine
Inventor: HORIKOSHI MASASHI
IPC: F02D41/34
Filed: 1981-08-21
Abstract: PURPOSE:To make it possible to restrict the discharge of fuel part that has not yet been  burned in an acceleration state by releasing an operation estimating a maximum basic injection amount during rapid accerelation by subjecting basic injection amounts at specified time and time before that to the weighted average while multiplying said average by a prescribed  factor. CONSTITUTION:In an injection amount controlling device 14, a basic injection amount is estimated through a basic injection operating circuit 21 by signals from an air flow meter 7 and  a rotational speed sensor 13, and each sensor input is corrected on a hybrid correction amount  operating circuit 22 and further in a correction multiplying circuit to provide a maximum injection amount signal, allowing an injection valve 5 to be driven. And, the correction operating circuit 22 releases the operation of the maximum injection amount responding to the rapid  increase of an intake amount signal 7 during rapid acceleration, and the basic injection  amount is applied as it is to the injection valve 5. In this way, when air is warmed up with  the engine revolution beyond a prescribed revolution, and a throttle valve 4 is opened with the  air intake amount less than a prescribed one, a maximum injection amount is injected as mild acceleration, and a basic injection amount in the case of rapid accerelation. Accordingly, the  discharge restriction of fuel part that has not yet been burned and the improvement of an  engine operation performance can be made compatible.

Title: Ciphering system
Inventor: IKEDA TETSUYA
IPC: H04L9/06
Filed: 1986-06-06
Abstract: PURPOSE:To improve the security of ciphering maintainability by using a ROM for a random pattern ciphered or decoded so as to change an address signal of the ROM depending on the content of the ciphered data. CONSTITUTION:A transmission data processing section 11 processes the sent data in the unit of one work or byte and a transmission data is fed to an exclusive OR circuit 12. The circuit 12 applies ciphering by applying exclusive OR between transmission data and a random data in the unit of one word or byte outputted from the random pattern ROM 14. The ciphered data is converted into a serial data by a parallel/serial conversion circuit 13 in this way and sent. Then the content of the ROM 14 applying ciphering is not decoded in accordance with the order of address. Thus, the confidentiality security for ciphering maintainability is improved.
