Title: Shift system for sequential instruction
Inventor: NAKADA HIROSHI
IPC: G06F17/16
Filed: 1984-10-04
Abstract: PURPOSE:To extend a parallel executable part of an object program by comparing the arrangement of sequential items with that of intermediate texts and shifting the POST and WAIT instructions independently of each other. CONSTITUTION:The arrangement of sequential items is added to a WAIT instruction (VWT) to know the relation of dependence with a block B. Then the VWT can be shifted to a spot 2 from a spot 1 as long as no relation of dependence exists with the block B (range of alpha). Thus a part of beta is newly defined as a parallel executable part. For the shifts of both POST and WAIT instruction within a block, the POST instruction (VPT) set as shown in (a) is shifted in the direction opposite to the flow of control. While the VWT is shifted in the direction (IS) equal to the flow of control as shown in (b), and a part 1 is newly defined as a parallel executable part.

Title: Curved surface recognizing apparatus
Inventor: KAINO SHINJI
IPC: G01B11/24
Filed: 1984-10-04
Abstract: PURPOSE:To automate the recognition adjusting work and to improve accuracy and efficiency to a large extent, by computing the angle of a tangent line at a specified point of the surface to be tested as an angle deviation, based on the results of dynamic measurements of forming and disappearing processes of interference fringes at a plurality of positions. CONSTITUTION:A relative distance between an optical device 14 and a head 2 at points, which are displaced by specified distance on both sides of the circumferential direction of a curvature with respect to a specified point of the head 2 on the curved surface, is changed by a control device 16. Thus interference fringes are obtained. A difference DELTAy between relative distances y1 and y2 with respect to the maximum amplitude of the interference-fringe data is computed. A projection distance DELTAx between fixed points on both sides, which are projected on the (x) axis intersecting with the distance axis (y) ar a right angle, is computed. An angle theta between the (x) axis and a tangent line at a set point of the head 2 on the curved surface is computed by an approximate expression theta DELTAy/DELTAx. Thus the tangent angle at the gap part of the head 2 can be recognized highly accurately and automatically as an angle deviation theta.

Title: Ink-jet printing apparatus and method for forming mask pattern
Inventor: INOUE HIROO
IPC: B41J2/51
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To allow use of a small-power source without using a complicate constitution for printing control and prevent a degradation in print quality because of the small-power source in an ink-jet printing apparatus which prints on the basis of discharge data generated with the use of a mask. SOLUTION: When masks respectively corresponding to a plurality of scans of a head are to be formed, a predetermined mask pattern is first formed (step S2). While the head is shifted in units of patterns for every scan based on the mask pattern in a direction orthogonal to an arrangement direction of nozzles of the head (steps S3, S4, S7, S8), the number of mask dots discharged simultaneously at each scan, i.e., the number of nozzles is counted at each shifted pattern (step S5). Whether or not the counted maximum number of dots is larger than a predetermined limit value based on a source capacity of the apparatus is judged. A mask pattern having the maximum number of dots of not larger than the limit value can be generated in this manner (step S10).
