Title: Detecting device of marking position for electron beam exposure apparatus
Inventor: SHIMAZU NOBUO
IPC: H01L21/027
Filed: 1979-01-13
Abstract: PURPOSE:To detect a marking position of a large-sized chip with superior reproducibility and accuracy at high speed without moving a wafer by deflecting a beam using a large region deflecting power source. CONSTITUTION:Switches 13-16 are first turned off and a base mark 8 is transferred to a place near a light axis for detecting its position, then x coordinates L1+M1 are detected 10 and calculated 22 from the read-out L1 and the quantity of deflection M1 of a length measuring instrument 9. Next the switch 13 is turned on, and a board 6 is moved for approximately -l in an x direction so as to measure 9 the actual volume of transference L2. A beam is deflected 5 by a base voltage 17 by -l. When the deflection volume of the mark is M2, L2+M2-M1 becomes the volume of deflection based on the base voltage 17. In the same manner, the volume of deflection calibrated in reference to basic constant-voltage regulated power sources 18-20 is stored in a calculator 22. For detecting a mark 28, if the switches 13, 16 are turned on, the beam is discovered in the neighborhood of the mark 28. Thus, if the volume of deflection M3, M4 is obtained in the directions of x, y after detecting the mark, mark coordinates can be calculated. According to the construction, it is unnecessary to move the board for each mark, and an inexpensive and highly accurate detecting device can be obtained.

Filed: 1982-01-11
Abstract: PURPOSE:To eliminate generation of a code error for signal momentary interruption, by providing a means producing an arbitrary serial data according to the time continuously for a prescribed period for the end of a PCM signal. CONSTITUTION:A sound signal from a terminal 110 is sequentially compressed for time axis at each field period and intermittnelty outputted as a serial data X from a recording PCM processor 11.

IPC: B21D3/16
Filed: 1983-01-10
Abstract: PURPOSE:To correct the outside diameter of a splined shaft with good workability and accuracy by pressurizing the splined shaft and passing the same through a splined nut. CONSTITUTION:The outside diameter of a splined nut 3 is worked and is press- fitted into a heated holding ring 4, then the ring is allowed to cool to an ordinary temp. A pressure is exerted on a splined shaft 1 to pass the shaft about 1-3 times through the nut 3 thereby reducing and correcting the outside diameter thereof. The finish working of the shaft 1 is thus remarkably improved and the working method thereof requires just passing of the shaft through the splined nut, whereby the splined shaft is easily corrected.

Title: Abnormality deciding device of exhaust gas recirculating device
Inventor: KAWASE TAKASHI
IPC: F02M25/07
Filed: 1993-01-08
Abstract: PURPOSE:To decide the abnormal condition of an EGR(exhaust gas recirculating) device without confounding with the other abnormality of the engine. CONSTITUTION:An ECU31 reads the throttle opening TA, the suction air amount Q, the engine rotation frequency NE, the cooling water temperature THW, and the like, depending on the detecting signals from sensors 15 to 18, 25, 26, and 30, and a status switch 29. And the CPU 31 decides whether it is in the EGR operating area or not from these read data, and calculates the basic ignition timings theta B1 and thetaB2 according to the deciding result. And the ECU 31 calculates log angle amounts thetaK1 and thetaK2 according to whether it is in the EGR operating area or not depending on the knock detecting signal from a knock sensor 27, in a KCS operating area. The ECU 31 decides an abnormal condition of an EGR device 20 from the difference of the log angle amounts thetaK1 and thetaK2 (= thetaK1-thetak2). Consequently, knocking generating causes other than the EGR device 20 are cancelled, and only the abnormal condition of the EGR device 20 is decided accurately.

Title: External input/output terminal
Inventor: OBA AKIRA
IPC: H01L23/12
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To secure bonding area which is required as an external input-output terminal and to achieve high-density wiring and high-density arrangement at the same time by setting the plane shape of the external input/output terminal as polygon in shape, and making one side of the polygon parallel with the wiring direction. SOLUTION: The planar shape of an external input/output terminal is formed not into a circular shape but is constituted into a shape wherein the side is provided in parallel with the wiring direction, and is formed into a polygon. Thus, the wiring- guiding density to the external input/output terminal is improved. Furthermore, the values of wiring width and the wiring interval required for forming the wiring are made to be the readily manufactured values. That is to say, when the wiring is made to pass between the external input/output terminals, for the wiring width and the wiring interval at the irregular octagon, the diameter of the circular pad is suppressed to approximately 100 microns, when the pitch of the external input/output terminal is set at 250 microns.  In the case of the irregular octagon, 137.87 microns are obtained, and the region wherein the wiring between the 250 micron pitches passes, is expanded. Thus, the wiring width can be made thick, and the miniaturizing technology can be realized in micron units.

Title: Method and apparatus for visual examination
Inventor: TAKAGI YUJI
IPC: G01N21/956
Filed: 1998-01-09
Abstract: PROBLEM TO BE SOLVED: To eliminate an erroneous detection by correcting uneven density and distortions of two images containing patterns which should be originally identical and comparing the both to detect and discriminate parts differing from each other as defects. SOLUTION: Images f (x, y) and g (x, y) from an image memory section are inputted by a roughly positioning circuit 21 to be roughly positioned. An uneven density correction circuit 22 receiving the results inputted corrects uneven density values of the patterns which should be originally identical and reduces any uneven density difference existing at parts without defect to such an extent that the difference can be recognized to be normal. Then, to remove effect by unsteady distortions of the images, positional deviations are corrected by a distortion correcting circuit 23 so that any distortion of the images will not be detected and discriminated as defects. The two images subjected to the correction of the distortions further undergoes a highly accurate positioning with a precisely positioning circuit 24.  A density circuit 25 performs a comparison processing of the images thus finished with the correction of the uneven density and distortions and the positioning and any different part therebetween is detected and discriminated as defect. This eliminates erroneous detection, thereby enabling highly reliable detection of fine defects.

IPC: H01J29/07
Filed: 1978-01-14
Abstract: PURPOSE: To simplify a process for manufacturing the shadow mask of a cathode- ray tube for a television set by using a low carbon steel contg. a specific amt. of Ti and Nb to enable annealing and leveling processes prior to press forming to be omitted.  
     CONSTITUTION: A steel contg. C<0.02%, Mn; 0.1W0.6%, sol. Al; 0.01W0.1% and Ti and/or Nb; <0.2% is used as raw material for a shadow mask. When Ti or Ni is added, Ti≥4×C% and Nb≥7.8×C% are satisfied. In case Ti and Ni are added, the value of Ti/4C+Nb/7.8C is regulated to above 1. This steel is hot rolled to a strip, which is then cold rolled once or more to a predetermined thickness and annealed. This strip is recrystallization softened at below 600°C, temper rolled, and pierced by photoetching. Since this strip has superior press formability, it is directly press formed to manufacture a shadow mask without carrying out annealing and leveling processes.
