Title: Semiconductor device and its production
Inventor: TANAKA AKIRA
IPC: H01S5/227
Filed: 1998-12-14
Abstract: PROBLEM TO BE SOLVED: To emit a beam in the vertical direction to the end surface of a substrate by varying tilt angles of two mutually facing sides of a ridge waveguide on the substrate, and proving selectively an energization easy layer on the top face of the ridge waveguide. SOLUTION: Tilting of left and right sides of a ridge waveguide 8 is asymmetrical due to formation on a tilt substrate. An energization easy layer 7 is formed selectively corresponding to the asymmetry of the ridge. That is, the left side of the ridge waveguide 8 is removed in order to allow the electric current injected via the energization easy layer 7 to spread at left and right of the ridge. In this case, the layer 7 is preferably provided so that a distance (a) from one end of the foot of the ridge and a distance (b) from the other end may be almost equal. Consequently the electrical current flows evenly left and right in the vicinity of the central part of the ridge waveguide 8. Therefore, the gain becomes symmetry left and right, and the spread of the optical mode becomes also symmetry. As a insult, beam is emitted vertically from the end face.

Title: Device and method for image feature extraction, monitor and inspection system, semiconductor exposure system, and interface system
Inventor: NOMURA HITOSHI
IPC: G06T7/60
Filed: 1999-12-15
Abstract: PROBLEM TO BE SOLVED: To enable an image feature extracting device, which monitors a field according to a picked-up image, to easily extract features of a body in the field at a high speed. SOLUTION: A differential image signal is generated by picking up an image of the field. This differential image signal is processed by lines to detect the left end edge and right end edge of the field. An expanding and contracting process is carried out for the detected left end edge and right end edge to remove dot noise and blur noise. Calculated values such as body area and a body position are found from both the end edges having noise removed and abnormality in the field is decided according to the calculated values. A series of those processes is for only both end edges of two points per line. The information processing quantity is much less than that of processes by pixels and the processes are fast and simple. Consequently, an image feature extracting device is actualized which is suitable, specially, for real-time monitoring by a moving picture.

Title: Cargo handling control method for industrial vehicle
Inventor: KAWASHIMA KAZUO
IPC: B66F9/22
Filed: 1991-12-25
Abstract: PURPOSE:To improve workability during lowering of a lift without damaging safety by a method wherein a controller for controlling a proportional solenoid valve located in an oil pressure circuit running to a cargo handling cylinder is formed such that the cargo handling cylinder operation speed, such as a lift lowering speed, is variable according to a load. CONSTITUTION:During running of an industrial vehicle, a control signal is set by a controller 6 based on an operation signal responding to an operation amount of a control lever 7 and a load from an oil pressure sensor 9, and outputted to a proportional solenoid valve 4. Namely, the control signal is set such that a control signal output for a cargo having a high load is gently increased and when a load is low, a control signal output is increased rapidly from a position exceeding a fine control region. When a load is low, the operation speed of a cargo handling cylinder 1 to a lever operation amount is increased and meanwhile, when a load is high, the operation speed of the cargo handling cylinder 1 is decreased, and this method improves workability during lowering of a lift without damaging safety.

Title: Image processor
Inventor: OBA SATORU
IPC: G06F3/153
Filed: 1991-12-26
Abstract: PURPOSE:To output a curve part without straight-line division approximation and to obtain an image of high character quality when an outline font whose contour is represented by a curve function is made into image data. CONSTITUTION:A data read means 11 reads data, which constitutes the contour of a character or figure pattern, out of a storage device. Then a curve part dividing means 12 divides a curve part which includes a Y-directional extremal value at the point and an edge table generating means 13 generates information on the start point and end point of painting-out operation. A painting-out means 14 expands the data into image data according to the generated information and outputs the processed image data through an output means 15. Consequently, an intersection with the Y line as edge table information in the edge table generating means 13 can be found unequivocally. Consequently, the image data which has no deterioration in quality can be outputted without approximating the curve part with straight lines.
