Title: Projection aligner
Inventor: TOGUCHI MANABU
IPC: H01L21/027
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To provide an alignment system which can detect position deviation with high accuracy and with high speed. SOLUTION: A mark provided on a reticle and a mark provided on reference member are comprised of a V shape mark and an inverted V shape mark respectively and position deviation between the both marks is detected by an image pickup means. A relative position change (ΔLx) of two images 41a and 41b, a position deviation (ΔX) of the X direction and a position deviation (ΔY) of the Y direction are measured according to ΔLy by detecting operation at once. Detecting sensitivities of position deviations of the X direction and the Y direction can be changed by changing combination of opening angles of two V shape marks 36 and 40 and detecting error in the detecting directions set with high sensitivity can be compressed.

Filed: 1988-05-23
Abstract: PURPOSE:To improve startability, by a method wherein, in a device which counts a cylinder discriminating signal, discriminates a cylinder based on the counting result, and performs control classified by a cylinder, during the starting of an engine, control made based on information of discrimination of cylinder in a first cylinder discriminating section is suspended. CONSTITUTION:During running of an engine, a cylinder intended to be ignited is discriminated such that a cam pulse signal from a cam angle sensor 6 is counted in a cylinder discriminating section by a counter 30 and a cylinder is decided by a cylinder discriminating means 31. Namely, the cylinder discriminating means 31 reads count of the counter 30 when a crank pulse signal A is discriminated by a crank pulse discriminating means 20, and clears the counter 30 after a cylinder is discriminated. In this case, a cylinder discrimination starting command means 33 suspends discrimination of a cylinder in a first cylinder discriminating section, and starts discrimination of a cylinder by means of a cam pulse signal in a next cylinder discriminating section.

IPC: H04J3/14
Filed: 1989-05-19
Abstract: PURPOSE:To decide an accurate signaling bit and to improve the reliability of a device by prohibiting the information of a change in a signaling bit to a display section when an error bit due to noise, etc., is detected. CONSTITUTION:A 1st n-stage forward protection means 11 and a 2nd n-stage forward protection means 23 are constituted respectively of 4 flip-flops. Moreover, an n-bit consecution detection means 12 is constituted of a NAND circuit 121 detecting consecutive 1s with the output Q of a FF in the 1st n-stage forward protection means 11 and a NAND circuit 122 detecting consecutive 0s with an inverted output, the inverse of Q of the FF. When a bit error takes place during the state of consecutive 1s in the signaling bits, an LED 35 is lighted by the initial consecutive 1s. The LED 35 is momentarily turned off by the bit error in a conventional circuit. However, in this invention, since the output (r) of the FF 9 does not go to a high level so long as the output (m) of an AND circuit 212 does not go to a high level for 4 consecutive clocks. the LED 35 does not go off.

Abstract: PURPOSE:To shorten the time required for restoration of the double fault by setting a bypass mode when no information is received from each remote station within a fixed time and the signals are received through the transmission lines of the 1st and 2nd systems respectively. CONSTITUTION:A master station 1 cyclically performs the exchange of information to the remote stations 21-23 respectively, confirms the presence of these remote stations, and also collects the disconnection information.

The bypass mode is also set when either one of remote stations detects the disconnection of the 1st system even if the information is received from each remote station within a fixed time. Then a normal mode is kept as long as the disconnection of the 1st system is not detected.

Title: Alignment device
Inventor: KIYOKUNI YOSHIHIKO
IPC: H01L21/68
Filed: 1988-05-27
Abstract: PURPOSE:To improve operating efficiency by positioning a target into an optical visual field while reducing the quantity of positional displacement of the target when the target in a sample is conformed and operated. CONSTITUTION:The second mask alignment of a wafer is inspected itself. Two- time movement is changed into a mean value because of second mask alignment at that time, and the corrected origin of an XY stage 4 is acquired by a moving average value. A mask is aligned while being observed by a microscope. Consequently, movement correction is predicted before mask alignment with reference to the first and second movement correction of the XY stage, and the XY stage 4 is returned automatically to the corrected origin. As a result, a target 21 in the wafer 1 is kept within a narrow microscope visual field 22 approximately positively, and the accuracy of the target is also improved. Accordingly, the correction time of mask alignment is shortened, and workhours are reduced.
