Title: System for automatically extracting lineaments
Inventor: MAEDA AKIRA
IPC: G06T1/00
Filed: 1985-05-08
Abstract: PURPOSE:To automatically extract lineaments with high accuracy by detecting a part whose gradation is changed linearly on a picture as a line segment of unit length depending on direction and making the sensitivity of detection dependant on direction so as to eliminate the effect due to the direction of sun ray irradiation. CONSTITUTION:A lateral skew conversion in 0 is applied to an original picture 21 to produce a skew picture 22. Succeedingly, the skew picture 22 is subject to vertical compression to obtain a line element picture 23, which is subject to lateral differentiation. This processing is applied to utilize the property that a point having a larger lateral gradation change on the line element picture shown a larger picture intensity and represents an edge at the position of a line element on the original picture. The result of processings above is subjected to threshold processing to output a binary coded picture. Then points isolated longitudinally are eliminated. Succeedingly, the picture is magnified vertically by (l) times and the skew conversion with an angle -0 is applied. The line element in the specific direction extracted through the processing is added one after another to the result of extraction in the other direction.

Title: Laser oscillator
Inventor: TERAI KIYOHISA
IPC: H01S3/097
Filed: 1992-04-16
Abstract: PURPOSE:To successfully improve the number of orders of mode of a laser beam with a simplified structure by eliminating an aperture. CONSTITUTION:Discharge bulbs 1 to 4 are coupled in a line and these tubes are filled with supplied laser gas. At the external circumference of the discharge bulbs 1 to 4, electrode pairs 11 to 14 are arranged around the laser beam axis. A high frequency power of 10MHz or lower is supplied to the electrode pairs 11 to 14. In this case, when a discharge frequency of laser gas is 10MHz or lower, an electrode layer which does not contribute to excitation of laser gas is formed in the proximity to the electrode pairs. Therefore, since an electrode layer is formed in the circular form, the number of orders of mode of laser beam can be improved without using an aperture.

Abstract: PURPOSE:To correct the position measuring error by a global positioning system(GPS) on the side of a moving body by together using a second position measuring means capable of specifying a position with high accuracy on the side of the moving body to calculate a position measuring error vector by the GPS. CONSTITUTION:A GPS satellite is a system capable of specifying a position by receiving the signals transmitted from a plurality of satellites on a plurality of orbits. When a second position measuring means 20 is effective, the output of the second position measuring means 20 is subtracted from the position measuring result due to a GPS by an error quantity calculation means 101 to calculate an error vector. Thereafter, when a sign post signal is not obtained or matching can not be normally executed by the advance to a region where no road data is present, the calculated error vector is used to perform positional correction to the position measuring result due to the GPS. That is, in a correction means 102, correction is performed by subtracting the error vector from the result of a GPS position measuring means 100.

IPC: B30B1/18
Filed: 1985-05-09
Abstract: PURPOSE:To increase the speed of a screw press so as to obtain ideal forging conditions and to improve productivity by rotating forward and backward a flywheel for a spindle by means of a motor contg. internally a flywheel and forward-backward revolving clutch and planetary reduction gears and providing a brake to the flywheel for the spindle. CONSTITUTION:The revolution of a driving shaft 14 is decelerated by the planetary reduction gears 30 when the air of the prescribed pressure is forced from A according to a forging operation to revolve forward the shaft 14. The revolution is then stored as kinetic energy from a low speed shaft 31 to the flywheel 32. This energy rotates a screw spindle 35 and a slide 38 is vertically moved by a nut 37 screwed to said spindle. The descending of the slide 38 stops when the kinetic energy of the flywheel 32 is thoroughly consumed by forging. The spindle flywheel 32 is then rotated backward by a friction plate 22 for the reversing clutch to raise the slide 38. The brake shoe 33 is provided to the flywheel 32 so that the spindle 35 can be stopped.

IPC: F24H1/46
Filed: 1993-03-30
Abstract: PURPOSE:To make it possible to fill hot water precisely to a set water level by a method wherein a filling flow rate per unit time in an initial stage of operation is used and when the flow rate is equal to or larger than a certain flow rate, sensing of inflection point is utilized, and when the flow rate is smaller than the certain flow rate, circulation judgement is repeated to decide a water level wherein make-up firing circulation is possible. CONSTITUTION:When a flow rate per unit time is equal to or larger than a certain value, two-side transfer is finished, and while one-side transfer, wherein filling hot-water into a bathtub is performed through a bathtub return pipe 21, bathtub feed pipe 22, and an inner-side pipe 11b of a bathtub circulation fitting 11, is being performed, sensed output of a bathtub water level sensor 52 is monitored by a controller 60 to sense a point of inflection. And a certain amount of water is filled into a bathtub 10 by two-side transfer so that the water level reaches a water level H which exceeds slightly a hole of the fitting 11. When a flow rate per unit time does not reach the certain value, the controller 60, after completion of the two-side transfer, changes over a three-way valve 51 to decide whether or not bathtub water circulates through a circulation circuit 20. As a result, hot water can be filled precisely to a set water level.

Abstract: PURPOSE:To invariably conduct a stable cueing of paper by a construction wherein a backlash amount specific to a gear mechanism of each printer is detected by using a paper detection sensor, and a cueing of paper is performed in consideration of the obtained backlash amount and a paper slack amount. CONSTITUTION:For example, from a point A where a paper detection sensor 5a is turned ON by continuous paper 4a which has been guided by a paper guide 6a and passed through the sensor 5, a stepping motor 1 conducts a normal line feed by the arbitrary number of steps (n) to reach a point B. Succeedingly, the motor 1 is rotated reverse, whereby the paper 4a is returned from a point C to a point E where the sensor 5a is turned OFF with a little delay from the action of the motor. At this time, the motor 1 is returned to a point D due to a backlash. The number of reverse line feed steps n' required for the motor to return from the point B to the point D is detected, and alpha=n'-n is calculated as a backlash amount specific to a gear mechanism. Thereafter, the motor 1 is rotated forward by the amount of N+alpha+beta and rotated reverse by the amount of alpha+beta, where beta and N are respectively a paper slack amount and a cueing amount each of which is represented by the number of steps.

Abstract: PROBLEM TO BE SOLVED: To firmly grow plants, by fixing preventive metal tools against collapse of earth on a slope and covering the slope with a wire netting and spraying a soil-base material composed of high quality soil and chemical fertirizer and mixed to form a slurry, on the slope to form a base body of soil. SOLUTION: Preventive metal tools 2 against collapse of earth are fitted and fixed at appropriate positions on a slope covered with mortar. Then, a wire netting 3 is fitted and fixed on the slope 1. Water is added in a composite material constituted of high-quality earth, organic earth, effective soil microbes, chemical fertirizer, curing agent, solidifying agent, preventive agent against erosion, and seeds and mixed with them to make a slurry. This soil-base material is sprayed on the slope to get an appropriate thickness to form a base body of soil. In this way, when the slope 1 covered with mortar is greened, the mortar is not required to peel off and hence, the greening is economically executed. The plants grow with elapsed time and the roots reach roots or the original bed of the slope 1 while changing the mortar to soil and prevent collapse of the slope.
