Patent JP-S56156038-A (JP)
Title: Optical signal receiving device
Inventor: MATSUMOTO YOSHIHIRO
IPC: H04B10/564
Filed: 1980-05-06
Abstract: PURPOSE:To ensure an accurate detection for a break of input signal, by securing an AND for a periodic input signal and a periodic MP (microplasma) noise with a clock signal and then applying the output AND to a comparator via an integral network to detect a difference of potential between the input signal and the noise. CONSTITUTION:The output of an equalization amplifying circuit 2 is supplied to a discriminating circuit 13 via a timing circuit 9 as well as to an AND circuit 8 to actuate an input signal break detecting circuit 7. In other words, in case a periodic input signal and a clock signal with its phase matched with the input signal are supplied to an AND circuit 8, the pulse duration is increased with an increased output integrated by an integral network. However, a nonperiodic MP noise and a clock signal are supplied to the circuit 8 during a break of the input signal, and accordingly the pulse duration is reduced with a small integral output. Thus both integral outputs are compared with each other by a comparator 11 to ensure an accurate detection for a break of the input signal.

Title: Air purifier
Inventor: FUJIMURA YASUYUKI
IPC: B03C3/40
Filed: 1985-03-25
Abstract: PURPOSE:To obtain the titled apparatus capable of electrifying effectively the dust contained in air by providing symmetrically the flat plate-shaped anodes right and left in sandwiching a linear cathode between both anodes and providing an air suction port and a passage wherein the sucked air is separately flowed toward the anodes from the cathode to the cathode part. CONSTITUTION:The flat plate-shaped anodes 2 are insulated and fitted on a flat plate 8 provided parallel to a linear core of a linear cathode 1 in sandwiching the cathode 1 between both anodes. The flat plate 8 is covered by a safety cover 13 having a suction port 3 so that the air flow is separately flowed smoothly toward the anodes 2 of the right and the left via the cathode 1. The air passed through the anodes 2 is sent out along a fitting surface 14 parallel to the flat plate 8 from a discharge port 4. Therefore since the ionic wind is blown toward the electrodes of the right and the left from the cathode, the dirty air is not flowed along a wall surface and the dirt is hardly stuck on the wall surface. Since the electric power lines 15 having the wide ranges are caused, the electrifying effect of dust is excellent.

Title: Method and device for controlling herringbone in sheet-stock rolling mill
Inventor: YASUDA KENICHI
IPC: B21B37/28
Filed: 1985-03-27
Abstract: PURPOSE:To improve the yield of product as well as the productivity in a rolling line by eliminating the following correcting stage, by calculating and controlling a tension value at the inlet or outlet side of a mill in accordance with the generating degree of herringbone detected at the outlet side of the mill. CONSTITUTION:A herringbone detector 10 provided to the outlet side of a mill, detects a herringbone generated in the surface of a stock 1. A computing unit 11 fetches a detection signal of detector 10, to calculate and output an increment of outlet-side tension, to be provided to the stock 1 when the herringbone generates too much. A computing unit 12 outputs a new outlet-side tension value obtained by adding the increment to a present outlet-side tension value acting on the stock 1, measured by a tension meter 13 provided to the outlet side of the mill. As the sheet thickness of stock 1 decreases when the outlet-side tension increases too much, the inlet-side tension is controlled at the same time. In this way, the generation of herringbone is effectively prevented, and the yield of product is improved.

Filed: 1990-03-13
Abstract: PURPOSE:To obtain a galvanized steel sheet which is excellent in spot weldability and good in workability by utilizing an acidic galvanizing bath contg. a pH buffering agent having pH buffer action within a prescribed pH range together with an oxidizer and utilizing the steel sheet as a cathode in this bath and forming a plated layer consisting of zinc oxide or zinc hydroxide on the surface of the steel sheet. CONSTITUTION:This acidic galvanizing bath is utilized and a steel sheet is utilized as a cathode. A plated layer consisting of oxide or hydroxide of zinc is formed on the surface of this steel sheet by electroplating. In this case, a pH buffering agent having pH buffer action in a range within 5-12pH is incorporated as an essential component into the galvanizing bath. As a result, the excessive rise of pH in the plating bath due to reduction of hydrogen is inhibited at a time of electroplating by this pH buffering agent. Therefore it is prevented that the build-up amount of plating consisting of oxide or hydroxide of zinc formed on the surface of the steel sheet is made excessive. The galvanized steel sheet having the above-mentioned characteristics is obtained.
