IPC: G06K17/00
Filed: 2003-03-10
Abstract: <P>PROBLEM TO BE SOLVED: To avoid confusion when a plurality of IC cards are put close to each other.  <P>SOLUTION: A reader writer 2 request IDs from IC cards 3A and 3B. The IC cards 3A and 3B receive an ID request signal respectively and send ID numbers IDA and IDB to the reader writer 2. The reader writer 2 processes a selected ID (e.g. IDA) as specified to generate a degenerate key and sends a random number r1 ciphered with the degenerate key to the IC cards 3A and 3B. The IC cards 3A and 3B decipher the random number r1, but the IC card 3B is unable to decipher the random number r1 since the random number r1 is generated with the degenerate key using the IDA. The IC card 3A can decipher the random number r1 with the degenerate key generated from the IDA. This invention is applicable to, for example, authentication processing of an IC card and a reader writer.  <P>COPYRIGHT: (C)2004,JPO

Title: Ultrafine pulverizing, classifying, and crystallizing apparatus utilizing gaseous pressure and temperature difference by compulsive destruction of hydrothermal membrane
Inventor: ABE YOSHIHIRO
IPC: B02C19/18
Filed: 2003-02-10
Abstract: <P>PROBLEM TO BE SOLVED: To put carbon matter into the form of fine powder and to crystallize the powder in a nano size.  <P>SOLUTION: Raw materials and water are put into a hermetically sealable and openable vessel and are heated. When the pressure is rapidly extracted in the sufficiently raised state of temperature and pressure, pressure waves are generated in the inside by the disruption of a membrane boiling steam membrane and the raw materials are finely pulverized. At this time, the similar pressure waves are generated by the temperature difference even when cold water is injected in place of suddenly extracting the pressure. The similar pressure waves are otherwise generated by the disruption of the hydrothermal membranes as the result of agitation of the raw materials. The splashed raw materials which are ionized and classified in the above manner are collected.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Filed: 2003-03-24
Abstract: <P>PROBLEM TO BE SOLVED: To perform encoding by using a code conversion table such that the parities of code sequences are up to the time point where the codes became identical are different.  <P>SOLUTION: According to the codeword allocation in the code conversion table, the constraint length of the codeword at the time of decoding is three blocks and a relation q<SB>0</SB>≠q<SB>1</SB>is satisfied for an arbitrary information sequence by inserting a DC control bit in any of the first bit and the second bit of an information word. For example, an information sequence d<SB>0</SB>and an information sequence d<SB>1</SB>which are formed by respectively inserting temporary DC control bits 1 and 0 at the head of an information sequence [1,1,0,0,0,1,0] are encoded by using a predetermined code conversion table. In this case, an encoding state s<SB>0</SB>and an encoding state s<SB>1</SB>, when the state 3 is the start point, become identical at the third block: s<SB>0</SB>=s<SB>1</SB>=6. Since two's complement q<SB>0</SB>of the total of a code sequence c<SB>0</SB>until the codes become identical is 0 and two's complement q<SB>1</SB>of the total of the code sequence c<SB>1</SB>is 1, the relation q<SB>0</SB>≠q<SB>1</SB>is satisfied. The method can be applied to a recording and reproducing device or an encoding device.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To perform every coating process at the same liquid level.  <P>SOLUTION: A coating device performs coating while controlling the liquid level in a liquid tank to a constant value by monitoring the liquid level of a coat liquid in the liquid tank using a liquid level sensor 2 which outputs a first detection signal if the liquid level comes below a reference position, while outputting a second detection signal if it comes above the reference position. At least part of the coat liquid in the liquid tank is drained every time a single coating process is completed, so that the liquid level in the liquid tank is forcedly lowered (b) to such level as a liquid level sensor 52 outputs the first detection signal (ON->OFF). At that state, the liquid tank is refilled with the coat liquid to raise the liquid level in the liquid tank. The refilling of the coat liquid is stopped when the liquid level sensor 52 outputs the second detection signal (OFF->ON), thus keeping the liquid level at the reference position.  <P>COPYRIGHT: (C)2004,JPO
