THINKING POWER DEVELOPMENT SET USING SCREW MATCHING PANEL AND THINKING POWER TEST METHOD

摘要

PROBLEM TO BE SOLVED: To provide a thinking power development set using a screw matching panel capable of increasing thinking power, analytical ability and work ability etc. of an operator and capable of evaluating suitability and abilities of operators.;SOLUTION: The screw matching panel is a screw-hole arrangement of three rows which includes: a second row of plural small diameter holes drilled at regular intervals; and a first row and a third row of plural holes with diameter larger than that of the small diameter holes drilled at regular intervals in a row direction, which are disposed at both sides of the second row of the small diameter holes so that the holes in the neighboring rows forms a column being aligned in a straight line, in which the distance between the first row and the second row and the distance between the second row and the third row are d₁₂ and d₂₃ respectively. The screw matching panel also includes small diameter screws which are screwed into small diameter holes in the second row; and large diameter screws which are screwed respectively into the holes of a diameter larger than that of the small diameter holes in the first row and the third row. The distances of d₁₂ and d₂₃ are arranged so that, when a large diameter screw is screwed into a large diameter hole in a second row neighboring to any small diameter hole in the identical column prior to the small diameter holes in the first row and the third row, the small diameter screw cannot be screwed into any small diameter hole in the second row.;COPYRIGHT: (C)2015,JPO&INPIT
