Title: Early molding-rolling of assymmetric shape steel such as unequal sided and unequal thick angle steel, etc.
Inventor: WATANABE KAZUO
IPC: B21B1/08
Filed: 1978-06-01
Abstract: PURPOSE:To reduce the number of pass, prevent bending, and raise the efficiency of rolling by making early molding by applying a drafting to horizontal roll and one vertical roll every pass and also by fixing the other vertical roll at kissing or a definite position on the horizontal roll side all the time. CONSTITUTION:To prevent the protrusion of the web side @ portion of metal to be rolled, a square sectional shape of the steel piece or cast piece 17 is molded in advance by a double hole type rolling mill consisting of the horizontal rolls 20 and 21, and the metal 22 to be rolled, the shouldder portion (corresponding to the web side @ portion) of which is removed, is molded and rolled by an universal rolling mill while fixing the vertical roll 15 at a certain position all the time and also while drafting the vertical roll 16 every pass to obtain crude product. Thus, the position at which the web side and the vertical roll 15 meet each other is kept constant in making rolling and therefore high quality and bend-less product can be obtained without protrusions on the web side @ portion.

Title: Measuring gauge for relative slippage amount
Inventor: KONDO YOSHIYUKI
IPC: G01B11/00
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To accurately measure a small amount of relative slippage created between two members which are fastened with a contacting pressure without using an expensive measuring instrument in terms of a measuring gauge for the relative amount of slippage between two articles. SOLUTION: A plurality of parallel lines are printed at regular intervals on each of transparent thin plates. Both of the ends of the thin plate 1 on which horizontal parallel lines are printed and the thin plate 2 on which diagonal parallel lines are printed are bonded to each other in an interrelationship wherein an angle θbetween the parallel lines is satisfied with an equation of 'tanθ= 9:1/10-1/100'. Fixing adhesives 3, 4 to be adhered to members to be measured are attached to the other ends of both of the thin plates, respectively. In this condition, the thin plate 1 is attached to one article 5 by the adhesive 3 and the thin plate 2 is attached to the other article 6 by the adhesive 4 by nipping the contacting faces of the members. After that, the bonded section 7 of the thin plates 1, 2 is cut off to separate the thin plates when measuring.  When the articles 5, 6 are relatively moved to each other, a moire fringe which is created by the interference of the parallel lines on the thin plates shifts, thereby obtaining the relative slippage amount by reading the shifting amount.

Title: Method of forming fine pattern
IPC: H01L21/66
Filed: 1992-03-23
Abstract: PURPOSE:To facilitate formation of a high contrast scanning electron microscope image by a method wherein material having a high secondary electron emissivity is contained at least in a part of a resist mask. CONSTITUTION:Photoresist is uniformly applied to a foundation material layer 1 which is to be formed into a fine pattern and subjected to a soft baking treatment to form a single-layer soft resist film 2. Further, a fine pattern formed on a photomask is projected onto the photoresist film 2 and the photoresist film 2 is exposed and developed to form a resist mask 3 having an aperture 4 with a high aspect ratio. In an ordinary photolithography method, a hard baking treatment is performed after development. Because of heating in the treatment, a dehydration reaction of Mg(OH)2 MgO+H2O is promoted and MgO having a high secondary electron emissivity is produced in the photoresist mask. Mg(OH)2 which can produce material having a high secondary electron emissivity is contained in photoresist solution.

Title: Internal combustion engine exhaust gas re-circulation control device
Inventor: YAMADA DAISUKE
IPC: F02M25/07
Filed: 1994-04-04
Abstract: PURPOSE:To restrain a sudden torque shock by reducing the exhaust gas circulation within the delay time of the engine operation condition moving from a fuel non-increasing operation area to a fuel increasing operation area and fuel increase actually starts taking place. CONSTITUTION:A steady state exhaust gas temperature, which converges upon the operation condition at that time, is computed from a two-dimensional map of engine load and engine speed, and also a temperature rise delay time constant is computed by measuring an air flow rate and using the map of the air flow rate, by a control device 50 while the engine is operating. An exhaust gas temperature, which is the simulation of the actual exhaust gas temperature, is then computed by annealing the steady state exhaust gas with the temperature rise delay time constant. Judgment is then made as to whether fuel increase is presently being taken place or not and whether the steady state exhaust gas has exceeded the specified value (for example, 87 deg.C) or not. When the judgment is no, fuel increase is stopped or the exhaust gas re-circulation quantity is reduced to a degree where a problem will not occur, while, when the judgment is yes, fuel increase is put into action.
