Abstract: PURPOSE:To improve operativity for attaching an elastic member by forming an elastic member for applying elastic force to an stopper in a rotation regulating means which regulates a rotation of a support yoke with a wheel pivoted at a predetermined position, out of a plate-like spring material with the center bent. CONSTITUTION:A circular rotating body 5 is rotatably attached to between a pair of ball bearings 2, 3 fixed to a support shaft 4 which is hung from a mounting disk 1. A support yoke 6 having a pair of support leg pieces 6a is formed integrally with the rotating body 5 so that they protrude together and a wheel 7 is shaft-supported between lower ends of both support leg pieces 6a. In such a caster, a holder 8 is made protrude from an end of the mounting disk 1 while a cam pedal 9 is pivoted on a side wall 8c of the holder 8 and energized counterclockwise by a plate-like spring body 14. A rotation fixing plate 15 which is in a horseshoe-shape when planely viewed is attached on one side of the rotating body 1 and an engaging piece 9d of the cam pedal 9 is engaged with an opening 15c formed on the plate 15, thereby fixing the rotation of the rotating body 5.

Abstract: PURPOSE:To prolong the life of a cutting tool by correcting a feed value so that a workpiece can be cut by an unworn part of the cutting tool on a side opposite to the feed direction after the edge of the cutting tool has worn, and further by correcting the same so that the edge of the cutting tool cuts the workpiece with a predetermined diameter. CONSTITUTION:If the edge 11 of a cutting tool 10 has worn, the feed value of the cutting tool 10 is corrected so that at least one 11a of unworn parts of the edge 11 on the side opposite to the feed direction of the cutting tool 11 comes to a position where a workpiece 12 is cut. This correction can be attained by giving a feed value S2 which is larger than an initial feed value S1. In addition to this correction for the feed value S2, a cutting value d1 of the tool 10 is corrected so that the edge 11 of the tool 10 cuts the workpiece 12 with a predetermined diameter D. With this arrangement, a finish point A position on the workpiece 12 is cut by the unworn part 11a, and accordingly, it is possible to prevent the workpiece 12 from burring.

Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To prevent an image-density change which is caused by a variation in the position where a developing roll is stopped in the development. SOLUTION: In order to position a developing roll into a developing position, a developing-device assembly 10 is rotated by a motor 70.

Title: Method for recognizing pattern
Inventor: ADACHI RIICHI
IPC: G06F15/18
Filed: 1990-02-20
Abstract: PURPOSE:To rapidly and highly accurately recognize a pattern by accumulating a unique random number sequence having a feature extracting property to respective output part units of two output layers constituting a hierarchical network by learning to set up load coefficients. CONSTITUTION:A recognizing device 1 is formed by a hierarchical network constituted of two layers and the number of load coefficients is sharply reduced as compared with convensional BP method network constitution. The setting of the load coefficients of respective output part units 4a to 4b is rapidly executed by so-called random number string extract sequential addition by extracting a random number string having the feature extracting property capable of turning only one of outputs of the output part units 4a to 4n to positive or negative and directly and accumulatively adding or subtracting the extracted random number sequence in each learning pattern without executing trial-and-error adjustment using a teacher signal like the BP method. When the random number strings having the feature extracting property are accumulated, the feature extracting efficiency of the load coefficients is remarkably improved. Consequently, the sum of products output of the output parts units capable of surely outputting correct answers to a pattern applied after learning can be maximized and pattern recognition can be executed without generating an error.

Abstract: PURPOSE: To avoid occurrence of the crosstalk and the contrast reduction as well as to prevent the increment of power consumption by inhibiting the display driving  for the period during which the display information is being read into the memory  circuit.  
     CONSTITUTION: The display information, sent through oscillator circuit 10, divider circuit 20, adder circuit 30, 4-bit shift register 40, shift register 60 and others, is supplied via switch circuit 90 to decoder 100 in parallel to the series signal by the gate signal of timing signal generator circuit 110. Decoder 100 converts the display information into the display signal and then distributed to each digit through multiplexers 120 W 150 to be memorized in memory circuits 160 W 190. The display  signals are displayed on display unit 210 via Y electrode driving circuit 200 and X  electrode driving circuit 220. These actions are carried out by the timing signal of  circuit 110, and the driving for display is inhibited for unit 210 while circuits 160 W  190 are reading the display signals in. Thus, the effect of the transfer pulse can be  prevented from being given to unit 210.
