    摘要: A picture-forming method comprises the steps of providing picture forming elementary particles having different optical densities; controlling the areas occupied by the respective picture forming elementary particles; and representing gradient by said different picture forming elementary particles while limiting the percentage of the gradient level area represented by the highest density elementary particle to said picture forming elementary particles to under 70% of the total area repsesented by said respective different picture forming elementary particles, thereby giving a picture which does not feel "rough". Apparatus is also disclosed for performing the method.

    摘要: There is provided a liquid jet recording apparatus comprising: recording heads whose recording densities vary in response to drive signals; drive circuits to drive the recording heads; a control circuit to output the drive signals through the drive circuits to the recording heads; and a timing pulse generator to supply a drive timing pulse for the recording heads to the drive circuits. During the recording interval, the timing pulse generator supplies the drive timing pulse even when all of or a part of the recording heads are not driven. At this time, the control circuit controls the levels of the drive signals for the recording heads which are not driven to less than the coloring threshold value of those recording heads. As a result, the multihead drive control section in the multihead recording apparatus such as a full color printer can be constituted by a simple circuit.

    摘要: A numerical control method for a numerical control device which executes processing based on a machining program composed of multiple items of numerical control command data such as numerical command data and G-code data. Each item of the G-code data is expressed in the form of an alphabetic character G, a numerical value following G, and a code following the numerical value. The method includes inserting the items of G-code data in the machining program at suitable locations, subsequently discriminating the G-code data, and causing the numerical control device to execute processing specified by the discriminated G-code data.

    摘要: A numerical controller having an extended optional block skip function which permits selection of an optional block in a certain specific section of an execution program. In a numerical information storage medium is stored a cutting program in which a specific block is provided with skip object indicating information and skip select information, which is data for deciding whether to skip over the block and which can assume at least two values. Information indicating which ones of the blocks specified as the objects of optional block skip control are to be validated and invalidated is entered from a block select switch. A block skip circuit checks whether or not the skip object indicating information is present at the head or intermediate portion of each block. If not, the block is selected and, if the information is present, the skip select information is collated with information from the block select switch. As a result of this collation, when the block is to be invalidated, the block is skipped over and when the block is to be validated, the block is executed. A variety of cutting operations can be achieved using one cutting program, markedly improving the maneuverability and function of the numerical controller.
