Title: Heat resistant plastic optical fiber
Inventor: KOBAYASHI HISAAKI
IPC: C08L33/04
Filed: 1987-10-01
Abstract: PURPOSE:To improve light transmission performance, mechanical characteristics and heat resistance by incorporating a specific ratio of p-alkoxyphenol into a fiber component consisting of a polymer contg. an aliphat. N-substd. maleimide monomer unit. CONSTITUTION:The polymer contg. the aliphat. N-substd. maleimide monomer unit is used as the fiber component of a plastic optical fiber having a fiber- sheath structure. The kind of the p-alkoxyphenol is not particularly limited if said phenol does not deteriorate the light transmission performance. Hydrocarbons of 1 up to 8C are preferred for the substituent thereof by taking the stability, productivity, etc., of the compd. itself into consideration. The effect of improving the heat resistance is not developed if the compounding ratio thereof is below 30ppm. The heat resistance is conversely lowered and the light transmission performance is degraded as well if said ratio exceeds 5,000ppm.

IPC: H01J37/04
Filed: 1987-10-01
Abstract: PURPOSE:To make it simple to measure the gas pressure in an ionization chamber as well as to stabilize the quantity of ion beam current by making use of a definite relation existing between the gas pressure of the ionization chamber and repeller current or ionic current. CONSTITUTION:It is so designed that the gas pressure in an ionization chamber 1 is detected so as to be controlled to be maintained at constant while being compared with reference pressure. Since there exists a definite relation between the gas pressure in the ionization chamber 1 and repeller current or ionic current, the aforesaid pressure is measured by measuring repeller current or ionic current without effecting the gas pressure in the ionization chamber 1. It is so constituted that repeller current can be maintained at constant so as to be detected by a resistor 17, even if an acceleration power supply 19 is changed wherein a bias powers supply 16 is applied between a grid 11 and a repeller 13. Ionic current extracted by the application of the ion acceleration power supply 19 is detected by a resistor 20.

Abstract: PURPOSE:To easily obtain a wiring of a desired pattern and miniaturize it by forming a main wiring layer only on an adhesive layer formed into a desired pattern in a self-alignment manner to form the wiring. CONSTITUTION:An N<+> type diffusion region (drain region) 22 is formed in a P type silicon substrate 1, and an SiO2 layer 3 is formed on the P type silicon substrate 1 including the N<+> type diffusion region 22 together with a predetermined contact hole 4.

Moreover, the formation of the main wiring layer 12 only on the adhesive layer 11 in a self-alignment manner eliminates etching for metal 12 of a main wiring. This facilitates the formation of a desired pattern wiring. Further, no displacement of mask alignment can afford to miniaturize a semiconductor device.

Title: Metal detector
Inventor: MAEZAWA MITSUO
IPC: G01V3/10
Filed: 1995-09-01
Abstract: PROBLEM TO BE SOLVED: To certainly prevent an object to be inspected mixed with metal foreign matter from flowing to other processing process by a detection leak by making the transfer to detection operation impossible unless a detection capacity confirming test is performed. SOLUTION: When the power supply of a metal detection means (means 32) is turned ON, a control means 45 can preferentially enter a test mode according to an operation program. Then, a feed means (means 25) is operated to feed a test piece to the means 32 to detect the metal sphere of the test piece. When the detection of the metal sphere is judged by a judge means 40, the means 45 completes the test mode in such a state that the means 25 is operated as it is to change over the test mode to a usual detection mode to enable the detection operation of the object to be inspected. When the metal sphere is judged to be not detected by the means 40, if 30sec is not elapsed after the operation of the means 25 is started, the test piece is re-detected.  If 30sec is elapsed, the means 45 turns the power supply of the means 25 OFF on the basis of the signal of 'test not executed yet' or 'test failure' of the means 40 to prevent detection operation in such a state that the means 32 is not normal.

When the refractive index of the shaping prism 6 is specified to 1.45 or more and the enlarging magnification of the same is specified to 2.3 or less, the thinnest shaping prism 6 is obtained.

Abstract: PURPOSE:To make it possible to discriminate the state of the surface of an object in a short time without necessitating manual work, by a method wherein the number of times when a value of peripheral distribution data passes through a threshold value and is displaced is compared with a prescribed value. CONSTITUTION:The surface of a semiconductor wafer 5 wherein a large number of chips divided by dicing lines are formed is illuminated uniformly with illuminating light 6 by a vertical illumination part 3 and an image of the area of inspection thereof is picked up by a camera 4. This image is subjected to A/D conversion 8 and stored 9 and then a profile circuit 10 calculates profile data on the brightness of the image. Then, the peripheral part of the gray image is checked out in the directions X and Y. The results of this calculation are subjected to computation by an arithmetic control circuit 11 on the basis of the profile data in a prescribed direction. In other words, the maximum and minimum values are determined as to the data on the peripheral part in the direction Y and further a threshold value is set. The number of times when the value passes through the threshold value upward and is displaced and the number of times when the former passes through the latter downward are counted and the wafer is determined as nondefective when the results of the count are equal to or below the number of the dicing lines in the image respectively.

Title: Component corner position detection method and component image extract method
Inventor: MIYAJI SHIN
IPC: H05K13/04
Filed: 1995-09-27
Abstract: PROBLEM TO BE SOLVED: To prevent the processing time from being affected by a ilt angle of a component by converting a picked-up image into a component of an image of a polar coordinate system using the gravity center as an origin and obtaining a position of the picked-up image corresponding to a vertex of a high position of the image converted into the polar coordinate so as to obtain a component corner position. SOLUTION: A picked-up image is converted into an image of a polar coordinate system using a center of a nozzle as an origin (1). Based on the polar coordinate conversion image, a vertex coordinate of a high position (polar coordinate) and the number of high positions are detected (S2). Then whether or not the detected number of high positions is less than, e.g. 4 is discriminated (S3). When the detected number of the high positions is less than 4, a defect of sucked posture is discriminated (S4). When the detected number of the high positions is 4, the top coordinate of each high position (polar coordinate) undergoes inverse transformation to be the coordinate of XY coordinate system to obtain the position of four corners of the component image (S5). Thus, the effect onto the processing time due to a tilt angle of the component is avoided.
