Title: Production of steel bar
Inventor: FUJITA YONEAKI
IPC: B21B1/16
Filed: 1982-08-30
Abstract: PURPOSE:To produce inexpensively and easily a steel bar having high dimensional accuracy by incorporating plural units of three-roll type rolling mills and subjecting the three-roll type rolling mills and the rolling mills before and behind the same to tension-less control. CONSTITUTION:Round calibers are used in the 2Hi mill of, for example, an (i-2)th stand, and a three-roll mill of triangular calibers is used in an intermediate rolling mill which is a three-roll mill in an (i-1)th stand. A three-roll mill having round calibers is used in an (i) stand. Both three-roll mills and the two-roll mills before and behind the same are subjected to tension-less control. Then the dimensional variance before the 2Hi mill is rolled with the three-roll mill having the triangular calibers and is concentrated almost all to the variance of the size H. When the material is rolled with the three-roll mill having the round calibers in succession to said mill, the height (h) and width (b) of the material on the outlet side of the rolling mill are nearly constant because of DELTAb/DELTAH=0.

Title: Output waveform improving device of current detector
Inventor: KIWAKI HISAKATSU
IPC: G01R15/18
Filed: 1984-07-20
Abstract: PURPOSE:To remove pulsating output waveform distortion effectively without spoiling its responsibility by providing a means which detects either of the point of time when a magnetic core enters a reset period and the point of time when it is saturated during the period. CONSTITUTION:The reactor having primary winding and secondary winding N2 on the magnetic core Cr3 is used, the primary winding is connected to a reset resistance RP in series, and an operational amplifier OP is used to subtract the voltage across the secondary winding N2 from a load voltage EL. Then, a current flows through the reset resistance RP, i.e. primary winding as shown by an arrow. Therefore, when this component varies, the differential value of this variation, i.e. pulse voltage is generated at the secondary point, so the amplifier OP cancels a pulse voltage superposed on the load voltage and the output of the amplifer OP is used as a current detector output to improve the output waveform.

Title: Grinding and sweeping material for steel surface
Inventor: MIZOGUCHI IKUO
IPC: B24C11/00
Filed: 1979-11-19
Abstract: PURPOSE: To obtain the inexpensive grinding and sweeping material exellent in grinding and sweeping properties, by blending blast furnace slag.  
     CONSTITUTION: The so-called blast furnace water granulated slag that is obtained by rapidly cooling blast furnace slag is made up of a crystaline material and a vitreous material and the vitreous material is predominantly present therein. The blast furnace water granulated slag itself is not suitable to substitute for a steel surface grinding and sweeping material because its strength is low. In the present invention, a blast furnace slag is blended with a converter slag and then water-granulated to improve the water granulation strength to the optimum value as a grinding and sweeping material. Particularly, in densifying and rigidifying the blast furnace slag with the converter slag, to suppress the disintegration of the water granulation which is unfavorable to grinding and sweeping, the amount of the converter slag to be added is restricted up to 7wt%. As a result, the grinding and sweeping material having a long life and excellent in grinding and sweeping properties can be obtained.

IPC: H04L13/00
Filed: 1984-07-19
Abstract: PURPOSE:To reduce the hardware quantity by storing the reception data obtained after assembling and the error presence/absence information obtained in a frame reception mode to an FIFO memory when the frame of a high-level data link control means is received. CONSTITUTION:An assembling circuit 1 assembles the input serial data into the parallel data to output it to a switching circuit 3 and at the same time outputs the control information on the reception end of a flag showing the end of data assembly and the frame end to a control circuit 2. The circuit 2 monitors the idle state of a memory FIFO4 and also controls the circuit 3 according to the control information supplied to supply either one of control information on the parallel data, the end of flag reception, etc. to the FIFO4. The identification signal which decides whether the parallel data of the FIFO4 is equal to the control information or not is outputted to an interruption display circuit 5 together with the signal switch shows whether the effective information is stored in the FIFO4 or not. Then the circuit 5 outputs a read request to an external device 6 to take over the information stored in the FIFO4. Thus the device 6 takes over the data on the FIFO4 and reports the FIFO4 that the effective information is reduced by a piece.

Filed: 1978-12-06
Abstract: PURPOSE: To prevent a concretion phenomenon of solid balls to be used in removing soot, by successively pressurizing-sending or suction-transporting the solid balls extracted from a hopper to a separator tank by utilizing pressurized heated air supplied from a main engine or vacuum suction.  
     CONSTITUTION: A damper 8 is opened, and solid balls in a separator tank 7 are scattered from an upper portion of a boiler through a shoot pipe 9, a distributor 10 and diffusing instruments 11. The solid balls scattered fall into a hopper 17 while repeating collisions with the internal elements of the boiler. Thus, soot accumulated on the surfaces of the elements is exfoliated by means of the solid balls, and discharged from a chimney while being carried on the flows of gases. Since the solid balls are forwarded to a solid ball tank 4 by means of a screw conveyor 2 from the hopper 17, immediately sucked up by means of a suction nozzle 5 and lifted to the separator tank 7, there happens no danger that the solid balls concrete in the solid ball tank 4.

Title: Etching method
Inventor: NAGANAMI TSUNEHIRO
IPC: H01L21/3065
Filed: 1979-11-20
Abstract: PURPOSE:To prevent the heating-up of a substrate, to reduce the etching speed of a resist mask and to stabilize the etching process by a method wherein a plasma is generated intermittently. CONSTITUTION:When a plasma is generated intermittently, the temperature of a substrate is lower than that when it is generated continuously. Also, when the substrate temperature is high, the etching speed increases and a photo resist has a little larger temperature efficiency than Cr. Therefore, when the heating-up of the substrate is prevented by applying a resist mask on a Cr layer and generating the plasma intermittently, the etching speed becomes smaller than that it has been, and a stabilized etching of the Cr film can be performed using the resist mask having a uniform film thickness.
