Title: Method for molding rib member of thin web
Inventor: TSUDA OSAMU
IPC: B21K23/00
Filed: 1993-07-27
Abstract: PURPOSE:To mold a thin web member to a net shape by simultaneously executing press approach of a pair of segmental upper metal molds to each other and reduction on a lower metal mold and completing the pressurization of a web part by making the rolling reduction on the lower metal mold larger than the press approach quantity of the segmental metal molds to each other. CONSTITUTION:A first state completes the pressurization of the web part by simultaneously executing the press approach of pair of the segmental upper metal molds 8, 8' to each other and the reduction on the lower metal mold 9 by reduction of a pressurizing head 3 holding a pair of the segmental upper metal molds 8, 8' with edge rail grooves 4, 4' and by making the rolling reduction on the lower metal mold larger than the press approach quantity of the segmental metal molds to each other. This first stage and a second stage of completing the pressurization of the rib part by executing only the press approach of a pair of the segmental upper metal molds 8, 8' to each other are continuously executed. As a result, the threshold conditions of the metal mold pressure and shrink defects are averted in the entire pressure molding process thereof and, therefore, the desired rib member of the thin web is efficiently molded to the net shape without generating the metal mold deformation and the shrink defects.

Title: Semiconductor memory
Inventor: KAWAHARA AKIFUMI
IPC: G11C16/02
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To stabilize a deciding operation in the case of existing Vt of a cell near a standard value in a write decision of a flash memory. SOLUTION: Bit lines BL1, BL2 are respectively connected to memory cells 1-1, 1-2, and the line BL1 is connected to a sense amplifier 4 and a write circuit 5 via a selecting gate 3. The amplifier 4 is connected to an input/output bus DIO via an output buffer 8. A value of input/output bus DIO fed via a write data latch 7 and an output ROUT fed via a decision data latch 6 are input to the circuit 5. An output BBD is input to the amplifier 4. The amplifier 4 has two write decision levels, and switches the both according to the output BBD. The level in the case of the data BBD = '1' is set higher than in the case of the data = '0'. Thus, the stable decision data is output to the bus DIO immediately after Vt of the cell 101 exceeds the standard value.

Title: Method of controlling distributing of powder
Inventor: AYUBA ZENSAKU
IPC: B65G53/66
Filed: 1980-12-27
Abstract: PURPOSE: To equalize the flow rates of a mixture in all branch pipes for distributing powder by mixing it with gas, by comparing the flow rates in the branch pipes with one another and controling the flow rate of added gas to each branch pipe depending on the result of the comparison.  
     CONSTITUTION: Carrying air is mixed into coal pulverized to a prescribed grain size. The mixture is introduced into a reserve tank. After that, the mixture is pressurized so that it is conducted to a distributor 1. The mixture is distributed under high pressure from the distributor 1 to the tuyeres of a blast furnace through branch pipes S 1 WS n . The reference pressure of each of the branch pipes S 1 WS n  is detected by a pressure gauge PO at the distributor 1. The pressure values measured by the pressure gauge PO and other pressure gauges P 1 WP n  at the branch pipes S 1 WS n  are entered into pressure difference transmitters D 1 WD n  to determine the pressure differences. To equalize the pressure differences to one another, pressure difference signals are applied to the flow control valves V 1 W V n  of air pipes 3 to appropriately regulate the valves. The flow rates of the mix ture in the branch pipes S 1 WS n  are thus equalized to one another.

Abstract: PURPOSE:To make it possible to suppress the local increase of CO by a method wherein the air flow rate one stage of the AAP consisting of two vertical stages is controlled according to the ignition state of gas phase reducing burners. CONSTITUTION:In an AAP part, the air, which is excluded from the use for controlling the air-fuel ratio of a boiler as a whole at A-D stage burners and left unused, is poured in a furnace in order to completely burn CO in exhaust gas after combustion. In order to allow to arbitrarily distribute the total air flow rate command 100 of the AAP in the before-boiler side air flow rate command and the after-boiler side air flow rate command, the ratio of the before-boiler side air flow rate and the after-boiler side air flow rate is manually set at a setter 13. Further, the correction value corresponding to the output 11 of a generator is generated with a function generator 12 and added to the output signal of the ratio setter 13 in order to generate the before-boiler side air flow rate command 101. The after-boiler side air flow rate command 102 is obtained by subtracting the command 101 from the command 100 with a subtracter 16. Next, in order to allow to arbitrarily distribute the command 101 in every compartment, the ratio of the before-boiler left side air flow rate and the before- boiler right side air flow rate is arbitrarily and manually set at a before-boiler left/right ratio setter 17. The before-boiler left side air flow rate command 103 is generated by adding the correction signal, which corresponds to the output 11 of the same generator, to the output signal of the setter 17.
