Title: Security managing method for card type storage medium, card type storage medium and transaction device for card type storage medium
Inventor: TANAKA HIROSHI
IPC: G06Q10/00
Filed: 1994-08-01
Abstract: PURPOSE:To prevent illegal access from the outside to an IC card by setting the allowable number of times of access to a data file per transaction to the directory area of a storage part and checking the number of times of access for each transaction. CONSTITUTION:When a transaction between external devices (transaction device) is started, a counting means 4A of an IC card (card type information storage medium) 1A counts the number of times of access to the data file just after the start of the transaction. A comparing means 5A compares the number of times of access counted by the counting means 4A with an allowable number of times of access previously set to the directory area of a storage part 2A. When the number of times of access exceeds the allowable number of times of access as a result of comparison by the comparing means 5A, an error judging means 6A judges it as an occurrence of error and stops the transaction. Thus, the illegal access from the outside to the IC card 1A can be surely prevented.

Title: Display controlling system, display controlling device, and display device
Inventor: NISHIOKA KIYOKAZU
IPC: G09G5/00
Filed: 1990-07-06
Abstract: PURPOSE:To make an appropriate half-tone display even when the contrast varies by expressing the half tone of display dots by making an intermittent display which changes the ratio of the displaying period to the nondisplaying period in accordance with a change in the driving voltage of a displaying section. CONSTITUTION:When a contrast (liquid crystal driving voltage) is raised, a level detection circuit 23 detects that a contrast value 20 is 'large' and outputs a half tone selecting signal 24 as 'large'. Since the signal 24 is 'large', a half tone signal selection circuit 25 outputs a half tone signal A151 as a half tone signal 15. When the contrast is lowered, the circuit 25 outputs a half tone signal C153 as a half tone signal 15, since the half tone selecting signal 24 is 'small'. Thus a linear half tone display is always realized even when the contrast is changed, since the effective voltage of the half tone display is controlled. There fore, an appropriate half tone display can be performed even when the contrast varies.
