Filed: 1992-04-01
Abstract: PURPOSE:To stably produce a galvannealed steel sheet excellent in film characteristics without requiring particular conditions by using a high Si added steel sheet with high tensile strength as a material to be plated. CONSTITUTION:At the time of producing a galvannealed steel sheet by using a high tensile strength steel sheet with 0.1-1.5wt.% Si content as a material to be plated and applying preliminary iron plating to the steel sheet (it is preferable that, in the case of hot rolled steel plate, preliminary iron plating is done after surface grinding) prior to the production of the galvannealed steel sheet, the coating weight M (g/cm<2>) per side of preliminary iron plating is regulated so that it satisfies the relations in 0.05X[Si]XW<=W<=M-<=0.10X[Si]XW with respect to the coating weight W(g/cm<2>) of hot dipping and the content of [Si](wt.%) in the steel, or further, hot-dipping is done by using a hot-dip galvanizing bath where effective Al concentration (wt.%) is regulated to 0.07-0.16wt.%. Then alloying treatment is performed under the conditions where alloying temp. T('C) and alloying time (t)(sec) satisfy the relations in 370+1000XC<=T<=460+1000XC and 0.08XW'<=t<=0.5XW' [where W'=(coating weight of both sides)/2].

Abstract: PURPOSE:To improve heat conductivity of AlN by subjecting an AlN powder to preliminary forming to give a porous raw material and permeating AlN into pores of the porous raw material under CVD conditions to densify the raw material and growing an AlN crystal layer on the densified raw material. CONSTITUTION:AlCl3 source 7 is heated and AlCl3 vapor is fed from a gas feed inlet 3a in a reaction tank 1 by H2 stream and simultaneously mixed gas of prescribed amount of NH3 and H2 is fed from a gas feed inlet 3b into the reaction tank 1.

Inventor: FUJITA TATSUO
IPC: F23D11/44
Filed: 1989-04-28
Abstract: PURPOSE:To prevent the occurrence of backfire and blow-off at a low combustion amount period and to promote shortening flame at a high combustion amount period by a method wherein burner ports making a pair are positioned facing each other, a secondary air slit is divided into a plurality of pieces and positioned outside a primary combustion chamber wall, and the positions of the secondary air slits and the burner ports are arranged in a zigzagging state as seen from the central part of a primary combustion chamber. CONSTITUTION:Fuel-air mixture 40 is fed through burner ports 22 on both sides, positioned facing each other, to a primary combustion chamber 21, and after ignition, opposing flames 41 are formed. A secondary air slit 29 is divided into a plurality of pieces and positioned outside a primary combustion chamber wall 18. Further, the positions of the secondary air slits 29 and burner ports 22 are arranged in a zigzagging state as seen from the central part of the primary combustion chamber 21. Since the primary combustion chamber wall 18 and a fuel-air mixture feed passage 24 are cooled by means of secondary air 36, flame is prevented from forming backfire and stably brunt in the vicinity of the burner port 22, the velocity of flow of the secondary air 36 is decreased, and disturbance can be removed. Since the secondary air 36 does not enter a position above a primary flame but enters between primary flames, shortening of a secondary flame 43 is further promoted.

Abstract: PROBLEM TO BE SOLVED: To provide a microcomputer wherein influence upon a processing speed is minimized and, at the same time, noise occurrence is reduced. SOLUTION: This device is equipped with a bus change rate detection part 21 which detects whether a bit change rate of an address outputted by a CPU 2 is large or not, outputs a slew rate adjustment demand and a wait instruction when it is large, and a bus interface part 22 which performs slew rate adjustment in accordance with the slew rate adjustment demand and the wait instruction, and which inserts the wait in an access cycle and outputs the address outputted by the CPU 2 to a memory part by way of an address bus.  According to this method, when the bit change rate is large, that is, when an occurrence of noise is frequent, it is possible to reduce the occurrence of a noise by adjusting the slew rate and, at the same time, a transition time is made longer by this slew rate adjustment and the access time becomes long, but an effect which can complement increase in this access time can be obtained by inserting the wait.

IPC: G07D7/00
Filed: 1990-04-27
Abstract: PURPOSE:To improve the reliability of the discrimination of truth and to reduce cost by detecting the unevenness of ink, a contained carbon component, a pigments component, a metallic component and the quality of paper with a waveform through the use of an infrared ray sensor and collating it with the waveform of a real note stored previously. CONSTITUTION:When a paper money is inserted into an insertion path, a start switch is turned on and a driving motor is started. The mechanism of a transmission system is driven and the bank note passes through a transmission path at prescribed speed. The infrared ray sensor scans the unevenness of ink in the bank note, or the contained carbon component, the pigments component, the metallic component and the quality of paper at width more than 2mm of an irradiation surface in the center of a longitudinal direction with the passage, and catches them in terms of analog so as to transmit the signal to a memory. The memory checks whether the bank note agrees with the type of the bank note and the waveform applied to the type based on the transmitted signal. Namely, a waveform B does not agree with the waveform A of a real note in the case of a counterfeit paper money, and errors occur in the waveform B for respective counterfeit paper moneys.
