IPC: B21B45/02
Filed: 1982-07-07
Abstract: PURPOSE:To reduce the warp which occurs in the course of cooling and after cooling, and to raise the productivity, by water-cooling a web before the final finish rolling, holding a temperature difference of the web and a flange at a specified temperature during the time extending from the time of the final finish rolling to the time of the end of transformation, and water-cooling it in a U- shaped attitude. CONSTITUTION:The final finish rolling is executed, performing the web inside face water-cooling in an inverted U-shaped attitude as to a U-shaped sheet pile on a table roll. Subsequently, the web outside face water-cooling is performed in a U-shaped attitude continuously after the rolling. The cooling treatment in this case is executed in order to control a temperature difference of a web and a flange extending from the time of the final finish rolling and the end of ferrite transformation of the flange after the rolling, to 50 deg.C or below. Subsequently, after the transformation of the flange is ended, it is cut to prescribed length and is cooled on the cooling bed.

Abstract: PURPOSE:To measure a phase with high accuracy by operating the frequency of the input recorded on a shift register and detecting the phase of said input on the basis of sine and cosine local signals same in frequency and becoming 0 in a phase angle at a measuring time. CONSTITUTION:The input subjected to A/D conversion is taken in a shift register 7. From the point of time when an N-clock delay gate 5 becomes effective by a sampling pulse showing a phase measuring time, the register 7 of the (2N+1)-th stage stores (N) data at the sampling time and before and after said time. At first, a wave number counter 8 counts zero cross from the data of the register 7 and an operator 9 operates input frequency on the basis of the count value. Next, a (2N+1) local phase wherein the (N+1)-th phase becomes 0 deg. is generated on the basis of the operated frequency by a numerical value control oscillator 10 and local signals are generated by sine and cosine generators 13, 14. The outputs of said generators 13, 14 and the input data of the register 7 are operated by multipliers 11, 12, adders 15, 16 and an operator 17 to calculate a phase angle.

Title: Method of etching aluminum film
Inventor: KAMIHIRA KAZUTAKE
IPC: H01L21/306
Filed: 1987-05-18
Abstract: PURPOSE:To etch an Al film uniformly without damaging an ITO film with which the Al film is in contact in a depressurized etching process of the Al film by employing solution composed of phosphoric acid and nitrate added to it as etchant. CONSTITUTION:Solution composed of phosphoric acid and nitrate added to it is employed as etchant for a depressurized etching process of an Al film. For instance, ammonium nitrate and potassium nitrate can be used as the nitrate and, especially, ammonium nitrate is preferred. If the etchant composed only of phosphoric acid to which ammonium nitrate is not added at all is used, an ITO film is severely eroded during the etching process and completely lost when the etching of the Al film is finished. On the other hand, if at least 20g of ammonium nitride is added to 1l of phosphoric acid, the ITO film is not eroded at all during the etching of the Al film.

Title: Fuel injection controller
Inventor: SUGIYAMA HIDEO
IPC: F02D41/34
Filed: 1981-07-28
Abstract: PURPOSE:To accomplish a favorable combustion balance between cylinders, by injecting fuel by a signal of closing an ignition switch for the first cylinder. CONSTITUTION:When the fuel is injected synchronously with the ignition of the first cylinder, the intake condition largely differs between three cylinders, that is, the intake valve of the first cylinder being in the combustion stroke is closed, the intake valve of the second cyliner being in the intake stroke is opened, and the intake valve of the third cylinder being in the exhaust stroke is closed. Since the intake valve of the third cylinder is open at the time of fuel injection, injecting the fuel at the moment the piston is lowered to a position in proximity to the bottom dead center results in that the intake condition of the third cylinder approaches those of the other cylinders since the intake action of the third cylinder has been weakened even though the intake valve is stil opened. Accordingly, when the fuel is injected at the time of closing the ignition switch for the  first cylinder, the intake condition of the third cylinder approaches to those of  the other cylinders, a favorable combustion balance is attained between the  cylinders, and smooth rotation can be obtained.

CONSTITUTION:When a sensor PS1 is operated after an article to be transferred is fed into a first gauge table 1, a control circuit C accelerates the speed of a mortor M1 to make the speed of a transfer part 10 line speed, and it is made to be a fast feed speed at the time of disappearance of detection signal of the sensor PS1 or at the time of completion of cutting inter-running cutter 3. The clutch of group 1 is released when the sensor PS1 detects the next article to be transferred. When a sensor PS2 is operated, the clutch 11 of the rotary transfer part 10 is released. The operation is sequentially repeated in the respec tive groups 3, 4 and second gauge table. It is thus possible to enable fast feeding without damaging products.

Title: Device and method for detecting atm cell
Inventor: KINOSHITA HIROYUKI
IPC: H04L12/28
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To improve reliability by extracting a cell number showing the kind of ATM cell and a frame number showing its order, discriminating a valid cell, prescribed kind and continuity through the collation of header and discriminating a cell loss when the absence of continuity is shown more than prescribed times within a prescribed cycle. SOLUTION: An ATM cell detection and a matching detection part 1 extract the header of ATM cell and collate it with header data HDD and when they match, a matching detecting signal is outputted as the valid cell. A cell number detection part 2 extracts the cell number and frame number snowing the kind and order of ATM cell and collates them with prescribed patterns and when they match, a matching detecting signal is outputted. When the matching detecting signals of valid cell and cell number are not provided within the respective cycles of timing signals T1-T3 and the continuity of frame number is absent more than prescribed times, a cell loss detection part 6 outputs an alarm signal. Thus, the overlap, omission and order exchange or the like of ATM cells can be detected as well.

Title: Swirl chamber-type combustion chamber of diesel engine
Inventor: HATAURA KIYOSHI
IPC: F02B19/00
Filed: 1986-05-23
Abstract: PURPOSE:To enhance the air-utilization factor in the vicinity of the upper dead point in the main combustion chamber, by forming a recess, the starting-end of which faces an injection port, on a piston head in such a manner that the recess partly overlaps a valve recess. CONSTITUTION:A recess 7, the shape of which expands right and left as the position advances from the starting-end part 10 toward the tip part 12, is formed on a piston head 8 in such a manner that the recess 7 partly overlaps a valve recess 100. With this, even in the period, during which a piston 6 passes near the upper dead point, the injection port 2 is kept open to the starting-end part 10 of the recess 7. As a result, the combustion gas flow, which gushes out from the injection port 2 into the main combustion chamber 1, is able to smoothly advance the air in the recess 7 toward the tip part 12 of the recess 7 without resistance. Thus, the excessive spreading of the gas flow caused by an approach of the piston head (8) surface to the injection port 2 can appropriately be prevented. In addition, since the depth of the recess 7 can be increased by the amount of the overlapping of the recess 7 with the valve recess 100, the resistance of the combustion gas while advancing can be made smaller.
