IPC: B21B1/22
Filed: 1984-04-25
Abstract: PURPOSE:To control a tail end stop position with extremely high accuracy by deriving exactly the diameter of a coil which is being wound, and stopping a winder at the time point when a target tail end moving extent which follows variations of the diameter of the coil becomes equal to a tail end moving extent after the tail end has passed through a tail end passing detector actually. CONSTITUTION:A rotary pulse signal oscillator 20 is provided on a revolving shaft of a winder 21, and in accordance with its pulse signal, a coil diameter D is derived exactly by a coil diameter operator 12 until winding is completed, and following variations of the diameter D, a target tail end moving extent L is calculated by a tail end stop position setting device 15 until winding is completed. Also, by using the diameter D and said pulse signal, a tail end moving extent operator 13 calculates successively an actual tail end moving extent La after a passing signal when the tail end passes through a tail end passing detector 3 has been detected. From both the moving extents L, La, the remaining tail end length DELTAL is derived by a tail end stop control part 16, passes through a speed command part 8 together with a signal of the diameter D and decreases a rotating speed of the winder successively, and the winder is stopped at the time point when both the moving extents L, La have become equal to each other.

Abstract: PURPOSE:To improve the performance of response without losing stability in the control of sensitivity, by switching an input sensitivity stepwise at a feedforward control means, when a level of an input signal is changed to a level of a by-pass signal sufficiently lower than that of a main signal or its inverting level. CONSTITUTION:A station ST1i (where i=1-n) is connected in series via an optical transmission line 30. The transmission line 30 is provided with a by-pass 2i of a passive branching circuit comprising a half mirror. An input optical signal to each ST is converted into an electric signal at a photoelectric converting element P, amplified at a preamplifier A1 and a main amplifier A2, compared with a threshold voltage Vth by a comparator CMP, converted into a binary signal and given to a signal processing section in the ST. When the function is stopped at the ST11, the input to the ST12 is changed rapidly from the level of the main signal to that of the by-pass signal, and when the function is restored, the input is changed rapidly to the inverting level. Gain controlling signals Vc1, Vc2 corresponding to the main signal and the by-pass signal are selected at the feedforward controlling circuit FF, summed to a control signal of a feedback controlling circuit FB and the main amplifier A2 is controlled stepwise.

Title: Heat sink
Inventor: SAITO HIROSHI
IPC: H01L23/40
Filed: 1994-04-25
Abstract: PURPOSE:To improve the yield rate and the reliability of a hybrid integrated circuit device for high output power. CONSTITUTION:A heat sink 9, which mounts a power semiconductor device 1 and is connected to a circuit pattern 6 formed on a substrate 5, is formed in an approximately square pattern in a plan view. The pattern is formed so that the heights of a central part 9a, protruding parts 9b formed at the outer edge of the rear surface and the region between the central Part 9a and the protruding parts 9b are the approximately equal heights. The pattern is formed in a slope so that the heights of the central part 9a and parts other than the central part 9a and the region between the central part 9a and the protruding parts 9b become lower toward the outer edge of the bottom surface. Thus, the voids in solder 4 can be strikingly decreased, so that position deviation, rotation deviation and inclination become hard to occur.

Title: Waste water treatment method using iron
Inventor: FUJIE KOICHI
IPC: C02F1/70
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To remove nitrogen oxide ions and ammoniacal nitrogen by a simple operation by a method wherein waste water containing nitric acid nitrogen or nitrous acid nitrogen and phosphorus is brought into contact with iron to effect reaction and alkali is added to the reaction liquid to adjust the pH of the liquid to a specific value and gas is blown into the liquid to remove ammonia. SOLUTION: When nitrogen and phosphorus are removed from waste water, at first, nitrate ions and nitrite ions contained in waste water to be treated are brought into contact with iron to reduce the ions to nitrogen gas or ammonium ions. Next, alkali is added to the reaction liquid to adjust pH value thereof to 9-14 and gas is then blown into the liquid to remove ammonia so as to be carried by the gas. For treating ammonia in exhaust gas containing the ammonia, the gas is brought into contact with sulfuric acid solution to absorb and recover ammonia or the ammonia is burned or catalytically oxidized. And since ionized iron reacts with phosphorus components to form salt which cannot be easily dissolved, by removing the iron, phosphorus in the water to be treated can be removed.
