Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a digital filter in which dispenses with transfer of a first data memory and a second data memory, and a multiplicative step can be increased, and the precision of a filter can be improved, without damaging an arithmetic speed in a digital filter for thinning-out input data at a constant ratio. SOLUTION: Data are read from RAMs 63 and 64, in which input data 1 are written based on an address supplied from an address generator 51, and a value obtained by adding the data by an adder 30 is multiplied by a coefficient read from an ROM 71. The input data are divided into blocks constituted of N pieces of data and alternately stored in first and second memories. The addresses of the first and second data memories are calculated from the first and second numbers which indicate the block numbers of the block constituted of the N pieces of data, and the third number which indicates the location of data in the block.

Title: Temperature control method of preform heating body
Inventor: SUGIYAMA MASAO
IPC: B29C35/08
Filed: 1989-05-26
Abstract: PURPOSE:To manufacture plastic bottles which are free from dispersion in qualities by fixing a temperature of an individual preform, by fixing a feeding quantity of heating while making at least a heating body's round of a rounding path. CONSTITUTION:A temperature of a heating body 21 is sampled once by an infrared thermometer 32 while making a heating body's round of a station table 6, a result of which is sent to a controlling device. An established reference value is compared with a sampled result, based on which a necessary amount of electric power is fed to the first induction heating coil 28 from a high-fre quency oscillator until the next measured value is applied to the controlling device, in the controlling device. Therefore, since the same amount of heat is given to the whole of the heating body 21 from a heating body heating zone 27, even if a temperature difference is generated on the individual heating bodies 21 in the beginning, the difference is reduced with the lapse of time. Since an amount of electric power is fed by operating a difference with a desired temperature, temperatures of the whole heating bodies 21 can be held under a uniform state at a desired established temperature.

Title: Operating method of blast furnace
Inventor: ICHIDA MORIMASA
IPC: C21B5/00
Filed: 1984-06-28
Abstract: PURPOSE:To enable the operation of a blast furance wherein a mixed material can be fed by interposing a layered feed method in the operating method wherein coke and ore are previously mixed and fed. CONSTITUTION:The air permeability can be improved in the blast furnace operation by the mixture feed method as compared with a layered feed method. Besides, enhanced controllability can be expected, since a hardly controllable fused zone is not formed. However, problems, such as an increase in heat loss from a furnace body due to an increase in a gas flow rate around the peripheral part of the furnace, a decrease in temp. at the furnance core part due to a decrease in the gas flow rate at the central part of the furnace, and an increase in a drop slip resulting from the slowdown of the falling velocity, can be caused. Accordingly, a layered feed method is applied at every mixture feed of plural charges. Consequently, said problems in the mixture feed method can be solved, and a stable blast furnace operation can be maintained by the mixture feed method.

Abstract: PURPOSE:To effectively reutilize Zn-contg. dust as an iron source in a molten iron pretreating device and converter by subjecting thee Zn-contg. dust generated from the molten iron pretreating device and converter to sintering and dezincification together with other iron making dust. CONSTITUTION:Zn is contained in the particulate dust emitted from pretreating stages for subjecting molten iron to predesiliconizing, predeesulfurizing and desulfurizing prior to decarburization refining of the molteen iron in a steel making furnace or the particulate dust generated at the time of steel making refining by the converter and, therefore, many sintered articles are crushed to generate much of fine powder of >=5mm at the time of mixing the dust described above with other iron making dust and subjecting the mixture to dezincification sintering, by which a ratio of circulative use of the returns as the fine powder is increased to 30 to 60% and the air permeability at the time of sintering is improved. The Zn in the form of ZnO in raw materials is reduced to metal Zn at a ratio of 20 to 55% at a relatively low temp. and this metal Zn is subjected to the dezincification treatment by evaporating and removing. This Zn is supplied as the low-Zn-content sintered ore to the molten iron pretreating device or the converter. The dust contg. the Zn at a high ratio generated from the molten iron pretreating device and converter is thus effectively reutilized as the iron source.

In the operation test at mass production of the dynamic logic circuit, each operation is performed by the drive clock 3 as the preposition and it is not preferred that static circuits exist in mixture. Thus, at test the level of the test input terminal 9 is logical 1 and the latch circuit 8 is made conductive to apply test.
