Title: Piston-piston rod assembly, manufacturing method and apparatus thereof
Inventor: KANEKO SHINJI
IPC: F16J1/12
Filed: 1979-03-20
Abstract: PURPOSE: To simplify the work by integrating a piston and a piston rod tight by cold caulking and by utilizing the restoring elastic force of the piston compressed and deformed in the axial direction.  
     CONSTITUTION: Flange-shaped caulked part 1b is formed on the end of small diameter part 1b of piston rod 1 by cold caulking. Piston 5 is pressure-inserted between caulked part 1b and stepped part 1d, with its length shortened compared  with its length in the axial direction when no external force is applied. Further, the  restoring force of elasticity of piston 5 is sustained by caulked part 1b and stepped  part 1d, and by their reaction, piston 5 is held under pressure between caulked part  1b and stepped part 1d. Thus, piston 5 and rod 1 are integrated tightly.

Filed: 1978-03-22
Abstract: PURPOSE:To realize a predictive restoration method for the picture element which decreases the number of the ambient picture elements to be utilized and thus can simplify the algorism of the predictive restoration. CONSTITUTION:The picture image composed of 9 picture elements and sampled in the square grid form is prepared; the density information is defined as S1, S5, S2 and S4 respectively for the up-down and right-left 4 picture elements which enclose adjacently central picture element S3 to undergo the predictive rstoration; at the same time element S3 is divided into 4 parts; and then the density is decided for each part of divided element S3 based on the relative relations between the density of element S3 and (S1+S2), (S1+S4), (S2+S5) and (S4+S5) each. As a result, the density of element S3 is decided. In this way, the predictive restoration can be given to the symmetrical picture elements in a comparatively simple way compared with the 8-picture element method with only the up-down and right-left picture elements which have the strong correlation with the predictive restoration symmetrical picture elements and without using all of the 8 picture elements.

IPC: B25J9/22
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To perform the optimum operation in accordance with a case merely by preparing one teaching program for individual operation each by preparing the teaching program after adding a degree of priority to a teaching point and operating a working means using a predetermined teaching point selected based on the degree of priority only. SOLUTION: A teaching part of a work robot A1 makes a work arm 31 perform desired operation through a control part, stores a point on a travel locus of a hand 32 at the time as a teaching point sequentially, and prepares teaching data using the teaching points. At this time, either of attributes, namely, a prerequisite point through which the hand 32 must pass and a selection point through which it passes arbitrarily, is added to each teaching point. When this work robot A1 is operated singly by teaching program P1, it is operated sequentially starting from an operation start point S1 using all the teaching points irrespective of the attributes. When its operation is done continuously, it skips the selection point sandwiched between the prerequisite points to operate it in the optimum state so that work efficiency can be improved.
