Abstract: An electronic payment system for making electronic money payments for transactions. A payment terminal stores a balance of electronic money for payment on a dealing by electronic money. A demanding terminal communicates with the payment terminal to demand the payment and a payment apparatus communicates with the demanding terminal and stores a balance of electronic money to correspond to an identification number of the payment terminal for allowing settlement on the dealing. The demanding terminal receives from the payment terminal the balance stored in the payment terminal and transmits the balance to the payment apparatus. The payment apparatus detects an improper use by checking the balance stored in the payment terminal, which was received from the demanding terminal, with the balance stored in the payment apparatus. The system of the present invention provides secure and convenient electronic money payment for a user's transaction.

Abstract: The base station 6 incorporates the line supervisor 8, the line switch 9, and the signal returner 10. If there is originated a call request signal for the mobile station 3 by the mobile station 2 after occurrence of a break in the line between the base station 6 and the control station 21, the line supervisor 8 notifies the line switch 9 of the line switch signal. In response to the line switch signal, the line switch 9 actuates the signal returner 10. Thereafter, the signal returner 10 returns the call request signal over the base station zone of the base station 6. This enables communication among the mobile stations 2 and 3 laid in the base station zone of the base station 6.

Abstract: A terminal portion (11) of a spark plug (10) and a connecting terminal (22) of an ignition coil (20) are connected through a coil spring (30) serving as a conductive member which in turn is covered with an insulating member (40) having a cap (41), a sleeve (47) and a bushing (48) and extending from the terminal portion (11) to a high-tension tower (21). A first air vent hole (44) is defined by an upper surface of a collar portion (42) of the cap (41) and a bottom surface of an ignition coil body (23) in intimate contact with the upper surface, and a plurality of reservoir spaces (45) having a greater volume than the first air vent hole (44) are formed in circumferentially spaced apart relation along the first air vent hole (44). A second air vent hole (46) is formed in the cap (41) for communication between the first air vent hole (44) and the interior of a plug hole (H).

Abstract: An ignition system for an internal combustion engine, comprising: a tubular insulating member which has a through-hole;a tubular terminal which is mounted in an upper portion of the through-hole; an ignition coil which has a first terminal;the first terminal being fitted into an upper portion of the terminal so as to be electrically connected to the terminal; a coiled spring which is attached to a lower portion of the terminal and is loosely fitted into a lower portion of the through-hole; a spark plug which has a second terminal fitted into the through-hole from a lower portion of the insulating member; the second terminal being brought into contact with the coiled spring so as to be electrically connected to the coiled spring; and a buckling preventive portion for reducing an inside diameter of the through-hole, which is provided at a portion of the through-hole between the lower portion of the terminal and an upper portion of the second terminal so as to prevent buckling of an intermediate portion of the c

Abstract: A construction for retaining an electrically conductive coiled spring which is inserted into a hollow of a high-voltage terminal subjected to a high voltage in an engine ignition system so as to electrically connect a head terminal of a spark plug or an ignition coil and the high-voltage terminal, the construction comprising: a first stopper which is formed on a side wall of the hollow of the high-voltage terminal so as to project into the hollow and is brought into contact with an insertion end of the coiled spring so as to retain the insertion end of the coiled spring; and a second stopper which is radially fitted around an outer surface of the side wall of the high-voltage terminal and is formed with a tongue piece and a projection; wherein the tongue piece is inserted between neighboring coil windings of the coiled spring in the hollow from a slit of the high-voltage terminal, while the projection is brought into engagement with a hole of the high-voltage terminal so as to be inserted between further neig

Abstract: In an insertion and engagement operation of a coil spring into the high tension terminal, the insertion end portion of the coil spring is inclined so that the projection portions may be located at upper and lower positions, and the outer diameter of the projection portions is approximately the same diameter as the outer diameter of the coil spring. The engagement portion of the high tension terminal includes an engagement hole, so that it can be visually confirmed that the insertion terminal portion of the coil spring has been engaged, the insertion end portion of the coil spring having been inclined in advance.
