Title: Cold lumping method of raw material for iron making
Inventor: FUJIMOTO MASAMI
IPC: C22B1/243
Filed: 1983-02-16
Abstract: PURPOSE:To lump raw material for iron making by quick hardening and to develop conveyable strength in a short time by compounding cement and quick setting cement with the raw material, molding said raw material by compression with flat rolls and bringing the molding into contact with water thereby setting quickly the molding. CONSTITUTION:Quick setting cement or ordinary cement and a cement accelerator are compounded and mixed with a raw material for iron making such as pellet raw material, pulverized ore, converter dust powder or the like. The compounded raw material is kneaded with a mixer 1 and is charged into a hopper 2 in the upper part of a flat roll compression molding machine where the raw material is compression-molded by the forcing pressure of a screw feeder 3 and the molding pressure of compression flat rolls 4. Water is sprayed from water feed nozzles to the molded and lumped ore to set quickly the ore and thereafter the ore is crushed with a crusher 6. The crushed ore is fed by a belt conveyor 8 for yard curing. The raw material for iron making is compressed and cold lumped with high productivity without pollution by the above-mentioned method.

Title: Method for accessing flash memory and flash memory storing data to be accessed by the same
Inventor: ISHIKAWA HIROKAZU
IPC: G11C29/04
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To provide a high-reliability flash memory by substituting a sector, where a correctable bit error occurs, without increasing access time so much. SOLUTION: Each sector of an AND type flash memory 1 is divided into data sector DS to be accessed when no defect occurs, spare sector SS for substituting a defective sector and table sector TS showing the correspondence of both the sectors DS and SS. Besides, the spare sector number of the spare sector SS for substituting the data sector DS is stored at a position corresponding to each data sector DS in a bad sector table area 13 for storing the table sector TS. Further, concerning the spare sector SS of the table sector TS, data showing the table sector TS to be substituted are stored in a control area CA. Thus, as a result, even when any sector becomes the defective sector, the proper sector can be accessed.

Title: Transceiver of power line carrier system
Inventor: TANAKA OSAMU
IPC: H04B3/54
Filed: 1983-02-15
Abstract: PURPOSE:To eliminate a high frequency carrier wave signal at a half cycle of an AC power supply from tailing on the next half cycle by increasing the impedance of a transceiver when the high frequency carrier wave signal is not transmitted to reduce the transmission loss of the signal in a power line carrier system. CONSTITUTION:A flip-flop 6 controlling by switching an output impedance of a driving circuit 5 is set at the transmission and reset after the timing of this transmission bit when a transmission display bit does not represent that the transmission display bit is being transmitted. Thus, an output impedance of the driving circuit 5 is always low during the transmission to prevent the leading edge and trailing edge waveform of the high frequency carrier signal from being distorted. Further, it is prevented that the high frequency carrier signal at the preceding half cycle from trailing on the signal at the succeeding half cycle. Thus, since the flip-flop 6 is reset during the receiving and an output impedance of the driving circuit 5 is high, even if many transceivers are connected to the power line, the impedance of the power line to high frequency carrier signals transmitted on the power line is not so much decreased, and even if the scale of the entire system is enlarged, the transmission loss of the high frequency signal is not increased so much.

Title: Divided command control device
Inventor: MAEDA AKIHIRO
IPC: B21C47/26
Filed: 1980-02-28
Abstract: PURPOSE: To improve the cutting accuracy of a wire rod coil by measuring the rolling length of the wire rod, and operating bisection time thereby bundling and cutting the wire rod coil equal to the divided times.  
     CONSTITUTION: When a wire rod passes finishing roll mills 12 and reaches a hot ingot detector 15, a detection signal is transmitted to a gate 26 and a clock 28. Then, the gate 26 allows the passage of the pulses from a pulse generator 14 during inputting of the detection signal; at the same time, it starts the clock 28. Then, when a counter 27 counts a predetermined number of the passed pulses, the content of the clock 28 of that time is registered into a register 1. Then, the counter 27 counts a required number of pulses and successively registers the contents of the clock 28 into a register 2. When the trailing end of the wire rod passes the detector 15, the gate 26 closes and the clock 28 stops. Then, from the total number of pulses and pulse separation, the time for bisecting the wire rod is obtained in an arithmetic device 30, and is registered in a register 31. Thence, the contents of the registers 31 are further transmitted to a timer 32. The timer is started by the coil arriving signal from a detector 20 and dividing shears 23 cut the coil when it goes equal to the value from the register 31.

Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To provide a character line width changing method, a character data processor and a recording medium by which the degree of freedom of character magnification can be enhanced and also to prevent a character crushing from being generated even when the character is a complicated character and to satisfactorily achieve the character magnification and, moreover, to prevent the overlapping between adjacent characters from being generated even when the magnified character stick out of a predetermined character frame.

Title: Core removing method
Inventor: WATABIKI SEIJI
IPC: B22D29/00
Filed: 1979-02-27
Abstract: PURPOSE:To elute away the core inserted into the casting in a short time without corrosion of the casting by combination of chemical treatment and vibration treatment such as giving of vibrations to the casting to promote the convection of the liquid in contact with the core at the time of causing the core react with the liquid and removing the same. CONSTITUTION:A core 2 made of quartz or the like having a through-hole 1 is inserted by stainless steel 3 and is set at the intermediate position of liquid cells 5, 5a by a seal 9. Next, e.g., an NaOH melt liquid 4 of 500 deg.C (heated by an outside heating furnace 8) is flowed from the liquid cell 5 to the liquid cell 5a with the through-hole 1 as a channel by the air pressure from an air change-over valve 10 so that the core 2 is eluted away. According to this method, the convection of the alkaline melt liquid in the core through-hole is accelerated and the stagnating layer thickness in the melt liquid in contact with the core 2 becomes small, hence the exclusion of the melt liquid rich with the product of reaction and the supply of the fresh melt liquid to take place of this are accelerated. Further, as compared to autoclave treatment, the treating apparatus and running cost are cheaper.
