Title: Portable medium
Inventor: FUJIMORI ATSUSHI
IPC: G06K19/06
Filed: 1987-12-09
Abstract: PURPOSE: To obtain a portable medium in which security is enhanced by adding a phosphor to an embossed pattern, thereby easily checking whether the embossed pattern is corrupted or not. CONSTITUTION: An embossed pattern 15 containing phosphor is formed on the surface of the basic material 11 of a card. The phosphor sustains transparency even if it is mixed with a transparent photosensitive resin and includes a phosphor having refractive index approximate to that of the photosensitive resin or a fluorescent dye of liquid organic based material, for example. In case of a malfunction IC card, fluorescence is emitted from the phosphor when the surface of the basic material 11 of card is irradiated with UV-rays, or the like, so long as a normal embossed pattern is employed. If a normal embossed pattern is removed and a false embossed pattern is reproduced of a general material, no fluorescence is emitted and corruption is found out thus enhancing security.

Title: Semiconductor electric potential supply device and semiconductor storage using the device
Inventor: UKITA MOTOMU
IPC: H01L21/8244
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To control an internal power supply voltage to a constant range by dropping external power supply voltage through the other transistor when the external power supply voltage is higher than the predetermined value and then supplying such reduced power supply voltage to a semiconductor storage circuit. SOLUTION: When an external voltage Vcc is rather low, an external voltage is supplied to an internal circuit 5 without reduction and when the external voltage Vcc is rather high, it is reduced and then supplied. Thereby, when the external voltage is high, reliability of transistor TR of an internal circuit C5 is assured and when the external voltage is low, it is not dropped so that data stored in the memory cell can be prevented from destruction. Even if a resistance value is fluctuated, the node N1 is determined by the sum of the threshold values of TRQ4 and TRQ5. Namely, when Vtp ' is assumed as the threshold value under the back gate effect of the P channel MOS TR, the operation point is set when the external power supply voltage Vcc becomes equal to 2Vtp '+Vtp . This operating point is never fluctuated largely if the resistance value R1 changes.  Therefore, the internal power supply voltage can be kept within the constant range.

Title: Divider
Inventor: BURAIAN JIEI SUPURAGU
IPC: G06F7/535
Filed: 1990-11-15
Abstract: PURPOSE: To reduce the division processing time by setting each quotient signal bit to 0 in the case that a partial remainder signal is 0 and setting it to one in the case that the partial remainder signal is smaller than 0. CONSTITUTION: When an s output value of an addition/subtraction device 22 is equal to 0, an S=0 signal is certainly confirmed; and when it is smaller than 0, an S<O signal is certainly confirmed. If dividend signal bits remaining in a dividend signal tower bit (DDL) register 30 are equal to 0 after left shift is performed many times (the number of times which is equal to afirst minus coefficient of dividend signal bits), a dd=0 signal is certaily confirmed. Then, dividend signal bits are always tested when the repeatedly generated partial remainder signal is 0. Quotient signal bits for repeat are set to one in response to the occurrence of the negative partial remainder signal. Thus, the time required for division processing is reduced, and the amount of required hardware is reduced.
