Title: Separation system of line segment and character
Inventor: KOIZUMI JIYUNICHI
IPC: G06T7/60
Filed: 1983-11-24
Abstract: PURPOSE:To decide whether a line figure or a character by processing the variation of an underfine flag of a label code of a lattice point obtained by the 1st scanning for a line segment followed by an end point, and repeating the 2nd scanning in the reverse direction. CONSTITUTION:An logical opertion circuit drawing 1 is image-picked up in an input part 2, and accumulated in a picture memory 4 through an A/D conversion part 3. A label code generation part 5 processes picture data and generates a lattice point label code. A recognition part 7 processes the code and recognizes a symbol, etc. When an undifined flag is set in the lattice point lable code, there is possility of a display of characters in the periphery. Therefore the recognition part 7 scans data of a code memory 6, and separation-recognizes a line segment and a character. Since an erroneous recognition may occur, separation recognition of a line segment and a character is executed twice and scanning is carried out in the regular and reverse directions. Thus a line segment and a character in the logical operation circuit drawing are properly separated and extracted, and the drawing can be automatically recognized.

Inventor: NEHASHI SATOSHI
IPC: G11B7/26
Filed: 1986-09-19
Abstract: PURPOSE:To detect the turning center simply and to accurately position and fix a disk hub in a short period by detecting the reflectance of the boundary between a 1st region formed with pregrooves or information pits of an optical disk and a 2nd region being a mirror surface without pregrooves and pits at one or more positions. CONSTITUTION:The reflectance of the region with pregrooves or engraved information pits of the optical disk 201 is lower, because of the scattering of light, than that of the region without them. The boundary part 201a of the region where pregrooves and information pits are engraved on the optical disk 201 is provided with reflectance detectors 202 to measure the intensity of reflection for the projected light. Thus, into which direction the optical disk 201 is deviated is discriminated by the difference between the outputs of the reflectance detectors 202a-202d. After the center of pregrooves or the information pits is discriminated in this way, the hub of optical disk is fixed by using an adhesive or the like in response with the result of discrimination.

Title: Idle speed control device of internal combustion engine
Inventor: ISHIKAWA HIROTO
IPC: F02P5/15
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To restrain a rotational change by input of a load by increasing an air quantity before the load is inputted, making an increases in engine rotating speed coincide with target rotating speed by controlling so as to delay the ignition timing, inputting the load when an increase in the air quantity reaches a prescribed value, and quickly increasing generating torque by canceling an ignition timing correction quantity. SOLUTION: For example, an ON condition of an electromagnetic clutch of an air conditioner is realized, the target step number of a stepper motor type ISC valve is increased like a dotted line (a part). Since the ISC valve cannot be driven more than one step in one time processing timing, the actual step number becomes like a continuous line (b part). When the ISC valve moves, an air quantity increases, and generating torque increases, and rotation increases in its condition. In order to correct this, the ignition timing is simultaneously controlled (c part) so as to delay, and the generating torque is restrained, and the occurrence of a rotational change is prevented. Afterwards, when a sufficient air quantity is obtained by the ISC valve (d part), an electromagnetic clutch is turned on, and delay control of the ignition timing is simultaneously stopped.

IPC: H01S3/22
Filed: 1986-09-22
Abstract: PURPOSE:To obtain a high output in an enhancement pulse oscillation mode by a method wherein, in a carbon dioxide gas laser capable of producing a continuous oscillation and a pulse oscillation using a mixed gas containing at least He, N<2> and CO<2> as a laser medium, the mixture ratio of the laser medium is set at He>=CO2>=N2. CONSTITUTION:As a carbon dioxide gas laser using a mixed gas containing He, N2 and CO2 as a laser medium, there are various types, yet an enhancement pulse oscillation mode can be adopted to any of the types. The mixing ratio of the mixed gas constituting the laser medium is set at He>=CO2>=N2 in this example. For example, in a carbon dioxide gas laser whose output in a continuous oscillation mode is 40 W, the mixing ratio is set at He:N2:CO2=4:0.7:0.7-4, for example, assuming the whole pressure of the mixed gas as 15 Torr. Thereby, the output at a high-pulse oscillation region can be also augmented along with the output at a low-pulse oscillation region in an enhancement oscillation mode and the processing speed of ceramics can be significantly improved applying this way to the cutting of the ceramics and so on.

Filed: 1992-07-30
Abstract: PURPOSE:To provide a method wherein the deformation resistance of a material is measured easily and with good accuracy up to a large distortion region in an arbitrary test shape according to the shape of an actual working operation. CONSTITUTION:Plastic deformation is given to a material, and the transition of power performed by an external force is found. On the other hand, the function form of the deformation resistance of a material is set, a proper estimated value is given to one or a plurality of unknown constants, plastic deformation is simulated by a computer by using a finite element method, and the transistion of power to be performed by an external force is found. The value of the unknown constants is changed until the error of both powers becomes a permissible range or lower, and the simulation of the finite element method is repeated. When the error becomes the permissible range or lower, the deformation resistance of the material is decided by using the value of the unknown constant at this time. The title measuring method is featured by adopting such a procedure.
