Title: Data transfer system for serial interface
Inventor: KAWABATA ICHIRO
IPC: G06F13/28
Filed: 1988-09-09
Abstract: PURPOSE:To realize the direct transfer of data to an internal register with no intervention of an intermediate buffer and therefore shortening data transfer time by setting previously an address at a DMA control part to designate a specific internal register. CONSTITUTION:An address is previously set at an address counter of each channel of a DMA control part 14 to designate a specific internal register. When the register selection data received from a host computer is stored in a buffer 101, a channel selection means 102 is started to identify the register number stored in the buffer 101 and to start the corresponding channel of the part 14. Then a DMA transfer request means 103 produces a DMA transfer request to an MPU 11 to drive the part 14 after the register data is received by the buffer 101. The part 14 outputs the address of the address counter of the started channel as an address of the data receiver and transfers the register data. Thus the data can be transferred directly to the internal register from a serial interface control part 10. As a result, the data transfer time is shortened.

Abstract: PROBLEM TO BE SOLVED: To easily stretch a waterproof sheet on a tunnel wall face by fixing a cut piece cut and resin from a fixing tape while unwinding the winding body of a sheet body fusing the fixing tape along the wall face. SOLUTION: A waterproof sheet 1 is formed by fusing the side edge of one hand of a fixing tape 3 to a sheet body 2 on the center part of the synthetic resin-made impervious sheet body 2, and the fixing tape 3 is notched to form a tongue-like cut piece 5 at specified intervals. The waterproof sheet 1 makes the cut piece 5 an upper side to be wound around a sheet roll 6, is unwound along the primary lining concrete wall face 7 of a mountain tunnel and the sheet 1 is stretched. At the time, the cut piece 5 is risen to drive a concrete nail to a wall face 7 through the cut piece 5 so as to fix the sheet 1 on the wall face 7. Thus, the sheet 1 can be easily and surely stretched on the wall face 7 by fixing the sheet 1 on the wall face 7 through the cut piece 5 of the fixing tape 3 while the sheet 1 is stretched.

Title: Production of sponge iron or pig iron from iron ore
Inventor: HAUK ROLF
IPC: C21B13/14
Filed: 1985-10-12
Abstract: A process for producing sponge iron from iron ore is described, which is reduced to sponge iron in a reduction shaft furnace by means of a hot reduction gas. For this purpose reduction gas at a temperature in the range 750 to 900 DEG  C. is introduced into shaft furnace (1) level with bustle plane (5) having been produced in a gasifier (2) then cooled and purified in a cyclone separator (12). Reduction gas is introduced below the bustle plane (5) at a temperature below that of the reduction gas introduced in the bustle plane and is preferably introduced into the shaft furnace (1) between 650 DEG  and 750 DEG C. Increased carburization of the sponge iron is obtained. Increased carbon separation also results through a volume increase, particularly by increasing the cross-section through the lower part of the shaft furnace. Carburization is also assisted in that the ratio of the reduction gas quantity supplied below the bustle plane is made as large as possible compared with the reduction gas quantity supplied in the bustle plane.

Title: Manufacture of multilayer ceramic electronic part
Inventor: FUKAE NOBUKUNI
IPC: C04B35/00
Filed: 1994-08-29
Abstract: PURPOSE: To prevent the occurrence of a density difference in a conductor section formed by using the paste of an electrode forming material containing a leveling agent for forming at least the peripheral part of the conductor section. CONSTITUTION: When a leveling agent is added to the paste of an electrode forming material, the film formed by applying the paste becomes fluidal and tends to level immediately after application and, therefore, the edges of conductor sections 2, 2,... formed by applying the paste to green sheets 1, 1,... become gentle slopes 3, 3,.... When the green sheets are stacked and pressed, no void is formed near the edges of the conductor sections and the density differences in the parts A, B, and C formed by the pressing process become zero or less. The added amount of the leveling agent can be 0.05-10wt.% based on the paste, but it is preferable to control the amount to 0.5-3wt.%. When the added amount is <0.05wt.%, the leveling effect becomes less and, when the amount is >10wt.%, the viscosity of the paste becomes low and the paste tends to sag down.

Title: Echo canceler
Inventor: SHIDA YASUNARI
IPC: H04B3/23
Filed: 1999-08-10
Abstract: PROBLEM TO BE SOLVED: To improve an echo suppress characteristic by interpolating the tap coefficient of a frequency domain echo calculating means and subsequently calculating the tap coefficient of a time domain echo calculating means. SOLUTION: An EC(echo canceler) 80 erases an echo due to a transmission signal made to take a roundabout way through a hybrid transformer 13. Then, the EC 80 is provided with a frequency interpolating part 81 interpolating the tap coefficient of a frequency domain EC 31, and an IFFT part 34 calculates the tap coefficient of a time domain EC 33 by using the interpolated tap coefficient. The part 81 interpolates a tap coefficient corresponding to a Nyquist frequency by taking the average value of two adjacent tap coefficients. Thus, it is possible to calculate the tap coefficient of a correct time domain EC 33 because of updating the tap coefficient corresponding to the Nyquist frequency where a frequency response becomes zero so that the tap coefficient of the EC 31 cannot be updated by interpolating the tap coefficient.
