IPC: E05B15/00
Filed: 2001-07-04
Abstract: PROBLEM TO BE SOLVED: To provide a cylinder lock which can prevent lock breakage due to an attack on a key guide thereof. SOLUTION: According to the cylinder key, an outer diameter at a front end of the key guide 12 of an inner cylinder 5 is minimized to such an extent that a radial difference between a key hole and a coaxial cylinder circumscribing the key hole assumes a minimum required value, except for a flange 25 on a base. On the other hand, an inner diameter of an opening at an outer end of a cylinder 23 sheathing the key guide 12 is minimized to a value in the range in which the key guide is rotatable with respect to the cylinder 23. Therefore, the engaging amount between the flange 25 of the key guide and an opening edge at the outer end of the cylinder in a radial direction is increased.

Title: Measuring method for extracting component of waviness on inspected surface
Inventor: OIDE HISASHI
IPC: G01B21/20
Filed: 2001-07-18
Abstract: PROBLEM TO BE SOLVED: To provide a method to measure the situation of waviness on an inspected surface two-dimensionally with high accuracy. SOLUTION: In the process 1, data are taken in by two-dimensionally measuring the configuration So of the inspected surface. In the process 2, the mildly rolling configuration Sv is calculated from the configuration So of the inspected surface measured in the process 1, where 'the mildly rolling configuration' means the configuration component of the inspected surface which does not include the rolling configuration component of higher order. In the process 3, the difference Δ is calculated between the configuration So measured in the process 1 and the mildly rolling configuration component Sv calculated in the process 2, that is, Δ=So-Sv, and in the measured configuration So of the inspected surface the difference Δ contains the rolling configuration component of higher order that is not contained by the mildly rolling configuration Sv calculated in the process 2.  The difference Δis therefore the extract of only the component of waviness that is the rolling configuration component of higher order on the inspected surface.
