Title: Inhibiting device of illegal access of ic card
Inventor: HAGIWARA ISAMU
IPC: G06F21/62
Filed: 1984-02-28
Abstract: PURPOSE:To inhibit an illegal or erroneous access to a data memory area of an IC card and its illegal use by storing a code for discriminating an IC card in itself, by the IC card checking to see whether a code transmitted from an IC card input device is coincident with the stored code before access to the data memory area and by invalidating the subsequent accesses for a certain period when they are dissident. CONSTITUTION:A code a12 received by an IC card is checked to be coincident with the code which the IC card itself stores, and when they are dissident, no response occurs. Code checking frequency is preset, and when they are equal within the specific access frequency, access start OK data are transmitted to a side A of an input device. When the dissident frequency of a code reaches the specific one, access termination OK data are transmitted to the side A of the input device from a side B of the IC card. Thus when an access to an area in which important data are stored is performed and the code dissident frequency reaches the specific value, the subsequent accesses are invalidated. Moreover, data safety can be made more complete by checking a code at the time of inputting a card.

Title: Electrolyte for driving of electrolytic capacitor
Inventor: IMOTO SEIJI
IPC: H01G9/035
Filed: 1990-02-20
Abstract: PURPOSE:To obtain an electrolyte with which a washing process can be adopted to an electrolytic capacitor without impairing the excellent characteristics obtained from the electrolyte heretofore in use by a method wherein pentamethyleneoxide of prescribed quantity or more is added to the electrolyte consisting of gamma-butyrolactone as the main solvent and alkylammonium salt of organic acid dissolved therein. CONSTITUTION:Pentamethylene oxide of 0.5wt.% is added to and dissolved in an electrolyte, having gamma-butyrolactone as the main solvent, in which alkylammonium salt of organic acid is dissolved. For example, an electrolyte, which is formed by dissolving tetramethylammonium hydrogenphthalate of 20g and pentamethylene oxide of 0.5g into gamma-butyrolactone, is used. As a result, the above-mentioned electrolyte suppresses the decomposition of chlorine ions even when halogenated hydrocarbon, which is used as a cleaning agent, is penetrated into a capacitor case, and also it prevents an aluminum electrode from corrosion caused by chlorine ions. Accordingly, the electrolytic capacitor, in which the above-mentioned electrolyte is used, withstands the cleaning agent, its reliability can be enhanced, and also it is advantageous in regard to cost.

Title: Driving control device for vehicle
Inventor: SAITO YOSHIHARU
IPC: B60W10/10
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To relieve an engaging shock at range switching time by fully closing throttle opening, and setting clutch oil pressure to a prescribed value larger than zero when engine speed is not less than a prescribed value at switching time to a travel range from a nontravel range of a shift range. SOLUTION: When a range detecting means 5 detects that a range is switched to a D range (a travel range) from an N range (a nontravel range), first of all, a control means 7 judges whether or not a clutch of a departure time engaging gear is engaged. When an engine speed NE detected by an engine speed detecting means 6 is not less than a prescribed value, that is, when the engine speed is abnormally high like an accelerator is stepped in the N range, engine speed down control is started after a timer is set. That is, throttle opening is fully closed '0' regardless of accelerator opening. At the same time, clutch oil pressure of a departure time engaging gear is made to stand by at a prescribed value in which this clutch does not have transmission capacity.
