Filed: 1995-08-24
Abstract: PROBLEM TO BE SOLVED: To absorb a mounting error even when an mounting error is produced on a stiffener by providing an extension width which extends one side of two duct boards which adjoin each other and joining each adjacent stiffener by way of the extension width. SOLUTION: This duct 1 consists of duct boards 2 and 3 and is reinforced with stiffeners 4 and 5 which wind up around the duct 1. The joining areas of the duct boards 2 and 3 are completely sealed by seal welding. The boards are welded over the whole length or partially so as to hold proper strength. In addition to that, each joining area of the adjacent boards 2 and 3 is welded by extending one duct board 2 so as to provide an extension width 13. Both stiffeners 4 and 5 are joined with each other by way of this extension width 13. The presence of this extension width 13 makes it possible to absorb pitch errors of the stiffeners 4 and 5 since the adjacent stiffeners 4 and 5 join each other by way of this extension width 1 even if the stiffeners 3 and 4 produce any pitch errors.

Title: Roll gap correcting method for bar mill
Inventor: TAKAHASHI YOICHI
IPC: B21B1/18
Filed: 1986-09-12
Abstract: PURPOSE:To permit rolling with high dimensional accuracy from the beginning after a caliber roll diameter change of the stands of a bar mill consisting of the plural stands by predicting and calculating the correction quantity of roll gaps prior to rolling. CONSTITUTION:The width size change quantity deltaBl of bar after the rolling in the path l is first predicted and calculated from the roll diameter change quantity  Dl of the stand l in the 1st step. The predicted width size change quantity deltaBk in the pass l is predicted and calculated in the 2nd step. The absolute value ¦deltaBk¦ of the product size change quantity deltaBk determined by the prediction and calculation is compared with set size tolerance epsilon and the operation is completed if said value is below epsilon in the 3rd step. However, the operation is progressed to the 4th step where the correction quantity of the roll gap is so calculated as to negate the product size change quantity deltaBk and the roll gaps of the respective stands are corrected to complete the operation if said value is larger than epsilon. As a result, the products having the high dimensional accuracy are obtd. from the first piece of the lot after the roll change.

Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recorder where the velocity and weight of a micro dot ink droplets can be fixed even if the Helmholtz period for each recording head fluctuates. SOLUTION: In recording heads whose Helmholtz period is large (Tc=8.0 μs), Twd1 is adjusted to 6.0 μs, 3/4 of Tc and in recording heads whose Helmholtz period is small (Tc=7.0 μs), Twd1 is adjusted to 7.0 μs equal to Tc, thereby increasing the velocity of ink droplets for, recording heads where Tc=8.0 μs and decreasing the velocity of ink droplets for those where Tc=7.0 μs. After that, by applying two different voltages, ink droplets are discharged from recording heads, the weight of discharged ink droplets is measured, and on the assumption that the weight of ink droplets changes linearly due to voltage, voltage is adjusted so that the weight of ink droplets of each head may be fixed.
