Abstract: PURPOSE:To attain the application of plural types of graphic information and to improve the unversal applicability of a model by dividing the formation elements of a knowledge data base into the attribute information and the graphic information and setting the position of the graphic information into the attribute information. CONSTITUTION:The physical information (the conditions necessary for solution of such problems like the structure, the action conditions, the specifications, etc.) are set to the attribute information together with the input/output connection information and the graphic information (the position of a data base including the picture information) set for each device or block. If a model consists of a motor 1 containing an interlock 3 and a switch 2, the information on the action of the motor 1 and the interlock 3 are inputted to the position of the graphic information included in the attribute information in terms of a problem to be solved. These two types of information are used with switch and different problems can be solved by sharing the model. In such a constitution, the universal applicability of the model itself is improved and the model can be used to the data base of only the graphic or physical information. Thus it is possible to reduce the production load of the model and to improve the quality of a knowledge data base.

Filed: 1992-08-27
Abstract: PURPOSE:To improve recording density by reducing a beam diameter of a laser beam in the peripheral direction of a disk than the beam diameter in the radial direction in the case of irradiating a laser beam a glass original disk and forming uneven cross-sectional shapes. CONSTITUTION:The laser beam from a laser light source 1 is divided to two directions by a polarizing beam splitter 2. One side exposes a groove part passing through an optical modulator 5. The other side, after passing through the optical modulator 4, passes through a beam shape converter 6 and exposes parts of an address signal, etc., and a ROM area. By the converter 6, the spot shape of the laser beam exposing the part of the address signal, etc., is changed, and the beam diameter in the peripheral direction of the disk is reduced than the beam diameter in the radial direction of the disk. These modulated two pieces of laser beams are synthesized by the polarizing beam splitter 8, and are converged on a photoresist 11 on the glass original disk 12 as two spots by a condenser lens 10. Thus, recording density in the longitudinal direction of the track is increased.

Title: Paper feeding device using cassette case
Inventor: SUGIURA TOSHIAKI
IPC: B65H1/04
Filed: 1988-09-13
Abstract: PURPOSE:To prevent the abnormality of the paper at the time of attaching/ detaching of a cassette case with the simple structure by forming a contact part contacting to a depressing action part, in a claw supporting member supporting the claw movably in about same direction with the laminated direc tion of the paper. CONSTITUTION:When a contact part 38 of a claw supporting arm 32 is contacted to a depressing roller 46 by further inserting of a cassette case 16, the depressing roller 46 rotately moving on the contact part 38 around a roller shaft 44 depresses the claw supporting arm 32 to the lower, resisting to the energizing force of a spring. Thereby, the front edge of the paper 14 in the most upper position passes through under a paper feeding roller 18 without contacting to it. When the inserting of the cassette case 16 is completed, the contacted condition of the contact part 38 with the depressing roller 46 is eliminated. As a result, the claw supporting arm 32 is pressed up to above by the spring, and the paper 14 in the most upper position is pressed to each paper feeding roller so as to be the possible condition for paper feeing.
