Title: Learning control method for shortening crop by stretch reducer
Inventor: YOSHIHARA TADASHI
IPC: B21B37/18
Filed: 1986-12-10
Abstract: PURPOSE:To improve the product yield by finding a difference between areas of a target and a measured thickness profiles, calculating variations in a roll peripheral speed at every stand, and setting the varied value for the succeeding rolling. CONSTITUTION:A thickness gage 30 is installed on the outlet side of a stretch reducer SR and measures a thickness of a steel tube 20 on the outlet side to find a measured thickness profile 110. Then, an area difference 130 formed by a previously set target thickness profile 120 and a measured thickness profile 110 is found and the difference 130 is adopted as a gain for a CEC parameter learning 140. Then, a calculated result of a CEC setting and control system 150 is used as a parameter in the succeeding rolling control for steel tubes of the same properties. Influences of noises and disturbances are eliminated because the measured thickness profile is properly evaluated and is used in the succeeding rolling control. Crops at a tube end are shortened to improve the product yield.

IPC: B23H7/36
Filed: 1988-11-22
Abstract: PURPOSE:To enable a machining liquid to be supplied to one of the optional machining holes provided at an electrode plate, by making the rotation dividing of a dividing shaft. CONSTITUTION:The outline shape of a machined matter is machined by means of an electrode plate 3 provided with a plurality of machining holes 41 - 45 which are in parallel and suitable for the formation process of the outline shape of the machined matter.

Title: Manufacture of semiconductor
Inventor: KURAMATA AKITO
IPC: C30B29/42
Filed: 1991-11-13
Abstract: PURPOSE:To obtain a semiconductor having a uniform distribution of specific resistance by doping impurities, each of which has a distribution coefficient of mutually opposite sign, at the same time and by selecting the doping material densities of the two kinds of the impurities at a ratio to compensate the difference in temperature. CONSTITUTION:Two kinds of the same conductivity-type impurities having the temperature dependency of a distribution coefficient TetaAXTetaB<0 being implanted at a doping material density which meets CA/CB=¦TetaB/TetaA¦, a semiconductor is deposited. TetaA and TetaB are rates of change about the temperatures of distribution coefficient etaA and etaB of the impurities and CA and CB are the doping material densities of the impurities. Then, the temperature dependency of the impurity density becomes zero and therefore the impurity density in the deposited semiconductor is fixed independent of the deposition temperature and there is no distribution of the impurity density even if there is a distribution of the substrate temperature. Consequently, a semiconductor of a uniform specific resistance can be deposited.

IPC: C21D8/02
Filed: 1994-11-30
Abstract: PURPOSE: To stably produce a hot rolled steel plate having uniform color tone in a plate-width direction and excellent in external appearance by controlling the coiling temp. of a hot rolled plate of low carbon steel to a specific temp. CONSTITUTION: A slab of steel, having a composition consisting of, by weight, 0.001-0.10% C, <0.07% Si, 0.02-0.60% Mn, <0.045% P, <0.045% S, <0.090% Al, <0.0100% N, and the balance Fe, is heated to 1000-1300 deg.C and hot-rolled, and the resultant hot rolled steel plate is coiled at a relatively low temp. not higher than 480 deg.C. Because of low coiling temp., adhesion between the steel plates forming a coil is reduced and the outside air is infiltrated into the plate width sensor part in the inner part of the coil and, as the result, the occurrence of nonuniformity in the thickness of an oxide film forming on the edge part and the center part of steel plate can be prevented. By this method, the hot rolled steel plate, free from nonuniformity of color tone in a steel plate width direction and excellent in external appearance, can be produced.

Title: Cadmium negative electrode for alkaline storage battery
Inventor: IKEYAMA SHOICHI
IPC: H01M4/24
Filed: 1987-11-25
Abstract: PURPOSE:To improve the utilization rate of negative electrode plate active substance extensively by including Fe3O4 powder in a nonsintering type Cd negative electrode. CONSTITUTION:In a nonsintering type Cd negative electrode composed by holding an active substance layer mainly of a Cd oxide or a Cd hydroxide in a conductive core material, Fe3O4 powder is included in the active substance. In the Cd negative electrode of such a composition, the Fe3O4 included in the active substance suppresses the reduction of surface area of the active substance owing to the generation of coarse crystals of the active substance particles generated by the repeated charge and discharge, and at the same time, the Fe3O4 which has a fair conductive property acts as a conductor. Thereby, the charge and discharge reaction proceed evenly as the whole battery, and the charge and discharge efficiency can be improved. The utilization rate of the Cd active substance is improved extensively, consequently.

IPC: B22C9/22
Filed: 1989-11-14
Abstract: PURPOSE:To obtain a defectless casting having no compression blow hole by moving a part of a die constituting a cavity relative to a casting through utilization of solidifying pressure and absorbing the motion margin between dies. CONSTITUTION:A rotor core 1 is fitted to a lower die 21. A motion margin absorbing part 26 is placed in a lower die fitting part 21k while taking account of compression amount due to solidification, and then an upper die 20 is fitted and secured to a lower die. Molten conductor material 6 such as aluminum molten is then poured and pressurized from below by means of a pressure plunger 8. Subsequently, the conductor material 6 is cooled and solidified. Compression amount at the time of solidification is absorbed because the lower die ascends to collapse the motion margin absorbing part 26 upon pressure solidification of the end ring part 21e. By such arrangement, a perfect casting having no compression blow hole can be obtained.
