Title: Foreign matter inspector
Inventor: AKIBA MASAKUNI
IPC: G01N21/94
Filed: 1978-01-27
Abstract: PURPOSE:To discriminate foregin matter rapidly and automatically by radiating parallel rays to the object under inspection from its side faces and detecting the reflected light through a polarizing plate. CONSTITUTION:For example, the semiconductor wafer in a cartridge 2 is trnsferred onto a rest table 4 and is fixed at its central part. The laser rays of a parallel ray generator 7 are then radiated parallel to the wafer surface from the side face of the semiconductor wafer 21. While the rest table 4 is being rotated, the reflected light is detected through a photoelectric transducer 15 and the sizes and number of foreign matter are detected based on the reflected light in the state where a polarizing plate 8 is installed at such a rotating angle at which the polarized light is cut by the polarizing plate 8 and only the non-polarized light may be detected. Since the inspection of the reflected light is accomplished by magnifying the wafer surfaces with the lenses 9, 10, 13, the field of view is narrow and therefore the detecting part is moved by moving the rest table 4 with feed driving parts 5, 6 relatively to the light detecting system consisting of the lenses 9, 10, etc., whereby the semiconductor wafer is completely inspected over its entire surface.

Title: Movement detecting circuit for chrominance signal
Inventor: KURIHARA RYOICHI
IPC: H04N11/20
Filed: 1988-01-18
Abstract: PURPOSE:To obtain a good chrominance movement signal without detection omission or error detection by using a difference signal between two frames as the chrominance movement signal and averaging it with the aid of a low pass filter besides. CONSTITUTION:A frame difference signal detection circuit 27 is constituted by a frame memory 25 having the delay time of one frame and a subtracter taking the difference between the input and output signal of it. The frame difference signal of an inputted television signal is detected and supplied to a band-pass filter 43. Then, the chrominance signal included to the first frame difference signal is extracted and separated. The two frames difference signal is made to be an absolute value by an absolute value circuit 47 and smoothed by the low-pass filter 48 after that. Thereby, a signal corresponding to movement information between the two frames of the chrominance signal is obtained. Thus, a movement detection signal (r) is made to be zero when it is a still picture. In case of an image of which contour of a substance to be filmed is the same but only a color component in the contour is different, the substance to be filmed can be judged as a moving picture.

Title: Optical position detector
Inventor: USHIKUBO KOHEI
IPC: G06F3/042
Filed: 1986-01-17
Abstract: PURPOSE:To prevent the malfunction due to external light by providing a member having a wavelength selectivity and a position detector including a light emitting element array and a light receiving element array and changing the extent of optical coupling between a pair of a light emitting element and a light receiving element in accordance with depression deformation of an elastic transparent plate to detect the depressed position. CONSTITUTION:Multilayered films 6A and 6B have a wavelength selectivity not to permit the light having a wavelength longer than the near infrared wavelength to pass through and do not permit near infrared external beams 65 and 66 of light to pass through. A transparent plate 6 is elastic; and when the transparent plate 6 is depressed with a finger 15, it is deformed, and a part of the light emitted from a light emitting element 9Ti is not totally reflected in the deformed position and is emitted out of the transparent plate 6 and is absorbed by the multilayered film 6A, and the quantity of light incident on a light receiving element 9Ri is reduced to lower the level of the output signal. Light reception signal levels for scanning of light emission and light reception of elements 9T1-9Tn and 9R1-9Rn in the state where the transparent plate 6 is not depressed with a finger are stored preliminarily in a memory 23 by a microprocessor 22; and when light reception signal levels are inputted at the next scanning, they are compared with light reception signal levels of individual light receiving elements in the preceding scanning which are stored in the memory 23. Thus, an optical position detector is obtained whose malfunction due to the external light is difficult to occur.

Abstract: PURPOSE:To freely regulate the leveling and ground contact pressures of a gravity-bottom landing type marine structure after installation by a method in which a level for the level and inclination of a platform and a ground contact pressure regulator by means of water pressure are provided. CONSTITUTION:During the float towing period, the inside water pressure in a level-regulating space 7 in a gravity-bottom landing type marine structure 1 is kept below the outside water pressure, and the bottom board 3 is closely contracted with the structure 1. In this case, water pressure from upper and lower mobile apertures 8 is sealed up by a rubber gasket and a distribution plate. Ballast water is injected into the balance space 6 to land the structure 1 to the seabed, and water is then injected into the level-regulating space 7 to adjust the level of the structure 1. When a given level is reached, the water in the space 7 is fixed. The structure 1 can thus be installed on uneven seabed or soft seabed.

Part of the interference light (k) is transmitted to go to external emitted light (t) and the remainder is fed back to become a signal (o) in the optical fiber. The film 11 is displaced with an acoustic signal and signal light on which intensity modulation corresponding to its is imposed is obtained. Thus, the high-reliability acoustic sensor which is easily assembled is obtained.

Abstract: PURPOSE:To shorten the queuing time of a central controller to prevent the degradation of the throughput, by suppressing an ineffective prefetch operation as much as possible to reduce the number of ineffective accesses from a channel controller to a main storage device. CONSTITUTION:A channel controller CHC is provided with a coincidence number counting circuit MCNT, a disaccord number counting circuit UCNT, a flip-flop FF, a front end differentiating circuit FD, a rear end differentiating circuit TD, and gates G1-G6. A collating circuit MAT collates an address request address a2 received from an input/output device IO with a prefetch address a1 generated by the prefetch function and sets a collation result (m) to logical ''1'' in case of the coincidence between them but sets it to logical ''0'' in case of disaccord. When the number of disaccords reaches a preliminarily determined value, the prefetch function is made ineffective to stop the prefetch from a main storage device MM. When the number of coincidences reaches a preliminarily determined value during this stop, the prefetch is restarted.
