Patent JP-H07141264-A (JP)
Title: Memory controller
Inventor: SHIBATA KOICHI
IPC: H04N1/32
Filed: 1993-11-19
Abstract: PURPOSE:To correctly repair and check data by rewriting new data, stored in a memory, with new data stored in a buffer when check sums match each other. CONSTITUTION:This memory control unit is a CPU 1 which controls a memory 2 and performs total control, and the memory 2 is a nonvolatile semiconductor memory such as a backup RAM and an E<2>PROM. Unless a recalculated check sum matches a check sum stored in the memory 2, the recaculated check sum is compared with a check sum stored in the buffer. When they match each other, the new data stored in the memory 2 are rewritten with the new data stored in the buffer, and the check sum stored in the memory 2 is rewritten with the check sum stored in the buffer. Therefore, corrections can easily be made if the data are not written correctly owing to a drop in source voltage for some reason.

Title: Data retrieving device
Inventor: MIYANAGA TAKAO
IPC: G06F17/30
Filed: 1988-11-19
Abstract: PURPOSE:To improve data retrieving speed by designating the address of data stored in a memory for every prescribed address interval, directly transferring the data of the address from the memory, and discriminating whether the data coincide with identification code data or not. CONSTITUTION:When the data are to be retrieved, a data transfer means 4 supplies the address obtained by successively adding the address interval corresponding to the data length of individual data to the leading address of the data to a memory 1 as retrieval address, and transfers the identification code data stored at the top of the individual data to a data retrieving means 5. The data retrieving means 5 discriminates whether the identification code data of the data to be retrieved from an identification code register 3 coincide with the data to be transferred from the memory 1 or not, and when both the data coincide with each other, the means 5 reads out the data of the following address of the retrieval address at that time from the memory 1, and discriminates whether the data coincide with the following identification code data or not. Thus, many data stored in the memory 1 can be retrieved at high speed.

The metallic layer consisting of Ag, Au, Ni, etc. is formed on the surface of the resultant powder to about 5-100mum thickness by a method such as plating. After the powder having the metallic layer is molded, the powder is calcined in an inert gaseous atmosphere or vacuum atmosphere at the temp. above the mp. of the metal to constitute the above- mentioned metallic layer. The electric contact point material of the sintered body formed by binding the powder particles to each other by the metal of the above-mentioned metallic layer is thereby obtd.

Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing a resin-laminated sheet which shows high productivity and the ability to manufacture the resin-laminated sheet of stable quality at a low manufacturing cost and continuously laminate the resin sheet without passing through a step to manufacture a semi-finished product in advance. SOLUTION: Two sheet manufacturing devices 21, 22 are arranged in such a manner that their sheet discharging directions are set in parallel. A resin sheet 61 to be discharged from one 21 of the sheet manufacturing devices is conveyed after diverting the direction of the sheet 61 in such a state that the front and the back face of the sheet 61 is reversed in the forward position of a direction in which the sheet 61 is discharged, and then the direction in which the resin sheet 61 proceeds is diverted in such a state that the front and the back face of the sheet 61 is reversed in a position where the sheet 61 crosses a resin sheet 62 to be discharged from the other sheet manufacturing device 22. Thus the directions in which both resin sheets 61, 62 are conveyed are set to coincide with each other and both resin sheets 61, 62 are pressed between rolls 25.

Abstract: PURPOSE: To produce a Cr-containing steel reduced in N content at a low cost. CONSTITUTION: At the time of refining a Cr-containing steel having about 5-50wt.% Cr content, decarburizing and denitriding refining is performed in a state where Cr concentration is lower by about 1-40% than the desired component value. In the course of decarburizing stage or after the decarburizing stage, when C level in the molten steel reaches about 0.05-0.5wt.%, a Cr source such as Fe-Cr is added at a time or by stages up to the Cr concentration level of the desired component value. By this method, the Cr-containing steel with reduced N content, in which N level in the molten steel is lowered down to about <0.020wt.%, can be refined.

Abstract: PROBLEM TO BE SOLVED: To improve the operation property and reliability of a thin film transistor by removing the impurities other than the objective species implanted by ion doping. SOLUTION: In the first place, a gate electrode 2 is patterned on an insulating substrate 1. Next, a gate insulating film 3 is made so as to cover the gate electrode 2.

Furthermore, an insulating film 5 is stacked on the semiconductor film 4, and then this is patterned after the shape of the gate electrode 2 and is processed into a channel stopper 7. The impurities including the objective species and unobjective species are ionized en block, and besides an accelerated electric field is applied to the semiconductor film 4, with the channel stopper 7 as a mask, so as to form a source region S and a drain region D. Lastly, the surface of the source region S and the drain region D is light-etched to remove the unobjective impurities caught on the surface.  Or, a barrier film may be removed by performing ion doping after forming this barrier film prior to ion doping.

Title: Electrode sheet for plasma etching
Inventor: KOKAJI KAZUMI
IPC: H01L21/302
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of unevenness in the temp. of an upper electrode at the time of etching and to prevent the generation of nonuniformity in the etching rate in the plane of a wafer. SOLUTION: The electrode plate is formed of glassy carbon in which thermal conductivity is regulated to >=5 W/m.K, preferably to >=8 W/m.K, and more preferably to >=10 W/m.K. The thermal conductivity referred here is calculated by the formula: thermal conductivity (W/m.K) = thermal diffusivity (cm<2> /S) ×density (g/cm<3> ) × specific heat (j/g.K) × 100. The specific heat of the glassy carbon is given by 0.63 (j/g.K). Therefore, by measuring the thermal diffusivity and density, the thermal conductivity can easily be calculated. The measurement of the thermal diffusivity can be executed by a laser flash method. As for the glassy carbon, there is no particular limitation on the raw material and the producing method therefor, only if it satisfies the above characteristics, but, as the raw material, furan resin or phenol resin is preferably used.

Abstract: PURPOSE:To obtain an automatic payment operating machine APOM having high safety by omitting counter slips which are conventionally produced by manual operations and at the same time attaining automatic collation processing within the APOM at the end of payment operation. CONSTITUTION:When refund money is given to an operator for plural APOMs, the amount of the relevant fund is written in a file on an information store card, e.g., an IC card 4 for each type of money. Then the refund money is given to the operator together with the card 4. Thus the operator sets the received refund money to the APOM together with insertion of the card 4. Then the refund amount is subtracted from the file of the card 4 for each type of money every time payment operation is carried out by an instruction received from a host system after the APOM is started. Then control is applied so that coincidence is secured between the balance of the refund money stored in the APOM and the balance on the file of the card 4.
