Title: Electronic computer
Inventor: YOSHIZAWA HIROAKI
IPC: G06F7/38
Filed: 1995-12-26
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy of solution of a functional equation of which solutions are multiple solutions or a functional equation of which solution is '0' in an electronic computer provided with a function calculating feature. SOLUTION: When a functional equation 'f(x)=0' to be solved is a functional equation having multiple solutions e.g. an x value to be successively converged by solving operation processing based upon Newton method is judged as an approximate value of the solution, the 10th digit of the x value is rounded, whether f(x)=0 is formed or not is judged, and at the time of judging the formation of the equation, the x value is displayed as the solution of the functional equation. When the functional equation 'f(x)=0' to be solved is a functional equation of which solution is '0', the x value to be successively converged by the solving operation processing based upon Newton method is judged as an approximate value of the solution '0', the approximate solution is rounded to '0', whether f(x)=0 is formed or not is judged.  At the time of judging the formation of the equation, the approximate solution x is displayed as the solution of the functional equation.

Title: Adjusting appliance for tension of guy by elastic body made from resin
Inventor: YAMAGUCHI HIROYUKI
IPC: H02G7/00
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To reduce the cost, and to make disassembling work safe and easy by using an elastic body made from resin such as polyurethane rubber as an elastic body for absorbing tension. SOLUTION: After inserting parallel bars 8, 9 into the inserting holes 17b, 17c of a first slide board 17 from the first locking board 7 of block A 1a through the use of nuts 19, 20, and after inserting the ends of the parallel bars into the inserting holes of a second locking board 24, they are united with nuts 22, 23. Besides, a hook 25 and the second locking board 24 are united by a bolt 27 through the use of nuts. This makes the construction simpler. Since tension generated inside a guy tension adjusting appliance 1 does not generate reaction force unless an adjusting nut 18 or 6 is screwed up, assembling is easy and safe. In addition, assembling on a site becomes easy too, even if the appliance is disassembled, carried, and brought to a mountainous region, etc.

Title: Device and method for lapping
Inventor: KITAJIMA KENKICHI
IPC: B24B37/27
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To increase the degree of flatness for the lapped surface of an article to be machined by setting the thickness of a machined article holding metal fitting thinner than the finishing thickness of the machined article and a difference between the thickness of the machined article holding metal fitting and the finishing thickness of the machined article to a specified value or higher. SOLUTION: The thickness (d) of a machined article holding metal fitting 32 is set thinner than the finishing thickness (e) of a machined article W such as a semiconductor wafer. The setting range of the thickness (d) of the machined article holding metal fitting 32 is set such that a difference (f) between the thickness (d) of the machined article holding metal fitting 32 and the finishing thickness (e) of the machined article W is 70μm or higher. If the difference (f) between the thicknesses (d) and (e) is lower than 70μm, then the degree of flatness for the lapped surface of the machined article W is not sufficiently increased.  If the thickness (d) of the machined article holding metal fitting 32 is too thin, a problem occurs in strength and thus the thickness (d) of the machined article holding metal fitting 32 must be set to half or more of the finishing thickness (e) of the machined article W. Thus, the degree of flatness for the lapped surface of the machined article W such as a semiconductor wafer is easily increased.
