Title: Optical recording medium and its recording, reproducing and erasing method
IPC: G11B11/105
Filed: 1992-04-01
Abstract: PURPOSE:To enable the execution of a reproducing operation only with a change in reflectivity and to miniaturize a recording and reproducing device by consisting a recording layer of a magnetic material and an org. high-polymer material contg. an org. material having absorption a both wavelengths of recording light and erasing light. CONSTITUTION:The recording layer 2 is formed on a substrate 1. This recording layer 2 is formed by dispersing the magnetic material 4 and the org. material 3 having absorption at the wavelength of the recording light or both of the recording and the erasing light into the org. high-polymer material. The reproducing operation of the recording layer of the optical recording medium in such a case can be executed by the change in the reflectivity alone and, therefore, the weight and size of the recording and reproducing device can be reduced. The recording layer can be easily formed by dispersing the above-mentioned material into a solvent, etc. Since a vapor deposition method is not required for forming the recording layer, unlike with the recording medium of the conventional magneto-optical system and, therefore, the productivity is excellent.

IPC: F23D3/18
Filed: 1980-06-11
Abstract: PURPOSE: To enlarge the combustion adjustment range and stabilize the combustion by making the diameter of the combustion cylinder smaller than that of the air control plate, in the subject device in whch burnt exhanst gas from an oil fan heater or the like is mixed with air for hot wind and the gaseous mixture is discharged into the room.  
     CONSTITUTION: The flow of combustion gas within a combustion cylinder 9 forms a recycling zone in which the gas flows upwards in the vicinity of the wall surface of the combustion cylinder 9, and downwards at the center part. With the same quantity of air blasted, the recycling zone varies depending upon the value of the diameter (d) of the combustion cylinder 9. That is, the larger is the diameter (d) of the combustion cylinder 9, the larger becomes the recyclind zone. Hence, the flow-out degree of unburnt gas and the like becomes great, and the exhaust gas at the normal combustion time is deteriorated and accompanies odors. In order to prevent the above disadvantages, the diameter (d) of the combustion cylinder 9 is made smaller than the diameter d u  of the air control plate 11, thereby cleaning the exhaust gas. Accordingly, the combustion qnantity variable range can be enlarged.

Abstract: PROBLEM TO BE SOLVED: To efficiently and accurately recognize a body by performing a matching process in order from a model for a body having more feature points appearing in an image and excluding the recognition positions of models for subsequent bodies having less feature points from objects of the matching process when the body corresponding to some model is recognized.

Further, the controller 2 projects the three-dimensional coordinates on a virtual vertical plane along the length of the road RD and performs a matching process by a two-dimensional model showing the side shape of a large-sized vehicle against the projection image.  Then the controller 2 performs a matching process by a two-dimensional model showing the side shape of a general vehicle against the projection image, but when a projection point group corresponding to the model for the large-size vehicle is already extracted in the former matching process, those projection points are excluded from the objects of the matching process.
