Title: Identification number recognition system
Inventor: ENOMOTO YOSHIHARU
IPC: G06Q40/00
Filed: 1991-04-16
Abstract: PURPOSE:To select the input collation system of an identification number by giving a processing switch instruction by means of setting a parameter from a host computer. CONSTITUTION:In an identification number recognition system, a command for identification number collation including the parameters of a first value and a second value is transmitted to an IC card reader/writer from the host computer. The IC card reader/writer analyzes the parameter. When the parameter is the first value, a host computer-side works the identification number into validity recognition information, transmits the validity recognition information to an IC card through the IC card reader/writer. When the parameter is the second value, an IC card reader/writer-side works the identification number into validity recognition information, transmits the validity recognition information to the IC card and an IC card-side executes the collation processing of validity recognition information.

Title: Water barrier sheet
Inventor: HATTORI YASUSHI
IPC: G01M3/04
Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To provide a water barrier sheet which can be easily laid and to detect the position of breaking over the entire area thereof. SOLUTION: The surface of a water barrier sheet 1 having specified thickness and area is sectioned into a plurality of areas ER, in each of which a transponder 10 is buried to transmit a specified response signal when receiving a specified query signal and antenna wires 11 of the transponder 10 are also buried covering the inside thereof ER almost entirely to form a water barrier sheet. As a result. when a breakage is caused in the water barrier sheet 1, the antenna wires 11 of the transponder 10 buried in the area involved are cut off and the transponder 10 is disabled to receive the query signal and to transmit the response signal. Therefore, the position of the breakage can be detected depending on the communication of the signals to or from the transponder 10.  In addition, since the antenna wires 11 of the transponder 10 entirely cover the area ER, almost all breakage in the sheet which will occur in the area ER can be detected.

Title: Preparation of semiconductor device
Inventor: SHIBATA SUNAO
IPC: H01L21/3213
Filed: 1982-05-19
Abstract: PURPOSE:To reduce over-etching through high speed etching of a film to be processed existing at the stepped part by diffusing impurity to the film to be processed formed at the stepped part. CONSTITUTION:A phosphor silicate glass (PSG) film 11 is deposited on a poly Si film 6 formed on a field oxide film 3 comprising the stepped part on an Si substrate 4. Then, when a PSG film 11 is etched, the PSG film 11 remains only at the side wall of stepped part of film 6. Next, phosphorus is diffused into the film 6 from the PSG film 11. Thereby, the phosphorus doped Si 12 is formed at the stepped part of film 6. The film 6 is then selectively etched through formation of resist in the desired pattern. At this time, an etching rate of Si 12 at the stepped part is faster several times than that of the non-doped film 6. Therefore, the Si 12 can be removed perfectly even if an excessive over-etching is not carried out. Accordingly, characteristic of transistor element is not deteriorated and accuracy of wiring pattern is not also degraded.

IPC: G06K7/08
Filed: 1979-07-05
Abstract: PURPOSE: To improve the reliability of data by printing bar codes in ink including magnetic components and then by magnetizing them in an even magnetic field.  
     CONSTITUTION: Card 1 is printed in magnetic ink to form bar codes of the part 2 and unprinted part 3. When widths of parts 2 and 3 are L, data "0" is expressed and when 1/2L, "1" is expressed. When magnetic resistance MR head 4 fed with electric current is moved over those bar codes, parts 2 and 3 differ in resistance value and this variation is extracted and processed by an FF circuit, so that data "0" and "1" can be read. Those bar codes form data hard to erase entirely in an external magnetic field and even when so, the data can easily restore. Since the magnetic filed is detected, the surface is tolerant to dirt and the reliability of data can be improved in an easy method.
