Abstract: A power window apparatus for a vehicle, which has an emergency switch being capable of cutting off a power-window-closing control switch element conjointly with the operation of a switch for opening the power window and has a contactor sliding between normally closed contacts and normally open contacts provided in the form of electrode patterns on a printed circuit board, whereon electrodes extend over the contactor sliding area and a entire surface of the board except the contactor sliding area is covered with a coating of waterproof resin. The emergency switch can eliminate an abnormal simultaneous energization of both the window-opening and closing relays in an accident (such as the vehicle sinking into water) by maintaining the conducting state of the normally open contact even if the exposed portions of the electrode patterns are partly damaged by electrolysis of material.

Abstract: A discharge-lamp lighting device has a housing with a power supply socket formed therein and accommodating a printed circuit board with a coil case having a primary coil formed by plural parallel plate-conductors insert-molded around the body thereof and a discharge lamp socket integrally fitted thereon and including a secondary coil therein. A lamp lighting circuit is formed by mounting the coil case on the printed circuit board. The discharge lamp lighting device is formed as a single solid device by potting all the components in the housing with insulating resin poured in a melted state and solidified therein, thus eliminating the need of providing a high-voltage cable between the circuitry and the lamp socket.

Abstract: An engine igniting coil device adapted to be mounted in a cylindrical bore of an engine and directly connected with an ignition plug therein has a coil case containing an igniting coil assembly and made of conductive magnetic material which is held at the ground potential level, thus preventing a decrease of output factor of the igniting coil of produced magnetic flux when spreading about and passing through a cylinder head of the engine and eliminating the possibility of leakage discharge from a high-voltage portion of the igniting coil assembly to the coil case and the cylinder head.

Abstract: An engine igniting coil device directly attachable to an igniting plug, wherein both primary and secondary coil bobbins have flangeless ends, the secondary coil bobbin has inwardly protruding ribs for coaxially supporting the flangeless end of the primary coil bobbin mounted therein and the secondary coil bobbin also has protrusions formed at its external wall apart from a high-voltage terminal of the secondary coil wound thereon and is coaxially mounted in a coil case by abutting its protrusions on an inner wall thereof, thus eliminating the possibility of damaging the bobbins by a large thermal stress produced in solidified insulating resin in a coil case by a differential thermal shrinkage in an axial direction and preventing a leakage current from a high-voltage side of the secondary coil bobbin to the coil case through a flange-like connection.

Abstract: An ignition coil winding method for spirally winding an element wire in conical banks of wire turns one by one in both forward and backward directions on a coil bobbin provides in particular that the number of wire turns placed in the reverse descending spiral winding direction is larger than that placed in the forward ascending spiral winding direction, thus forming a reliable coil with no falling-down of the banks of wire turns during the winding operation.

Abstract: An ignition coil winding method for spirally winding an element wire in conical banks of wire turns one by one around a coil bobbin provides in particular that a nozzle can vertically move toward and away from the coil bobbin according to a changing winding radius and can swing in the direction normal to the longitudinal axis of the bobbin to maintain constant tension of the element wire. This method also uses a nozzle whose opening diameter is 2 to 6 times larger than that of the element wire to eliminate oscillation of the element wire in the nozzle opening.

Abstract: In an engine igniting coil device comprising an ignition coil assembly potted integrally in a coil case by injecting melted insulating resin, a secondary coil is formed on a coil bobbin by bank winding an element wire in layers of wire turns one over another at a certain bank angle in an axial direction on the bobbin and by slope-winding of layers on the end portion of the bobbin by tapering the coil (by reducing the number of layers therein) in the winding direction. This allows setting a dielectric strength of interlayer insulation of the secondary coil according to a potential distribution therebetween, which is secured by forming an insulation resin layer of a reduced thickness between the coil case and the secondary coil of the secondary coil bobbin, thus realizing a compact engine-igniting coil device.

Abstract: An engine ignition coil device which comprises a coil case composed of a first cylindrical case and a second case having a small tubular hole in its center portion and an upper external shoulder at its open end fitted in an open end of the first case to form a closed end of the coil case and an internal unit assembled from a primary side coil bobbin, a secondary-side coil bobbin having a high-voltage terminal holder projecting from a center of its end flange portion, a rod-shaped core, and a high-voltage terminal attached to the high-voltage terminal holder and having a contact for electrically connecting an ignition plug thereto. The internal assembly is mounted in the coil case by inserting the high-voltage terminal holder in the small tubular hole of the secondary case with a tip of the contact projected outwardly therefrom and formed integrally with the coil case by injecting melted insulating resin into the coil case.

Abstract: A control mechanism for controlling hazard warning and turn indicator lamps in a vehicle is combined with a control lever in the vicinity of a steering wheel for easy operation. When the control lever is angularly displaced in a first direction, an elevator (displacing member) is displaced in a corresponding direction. At this time, a movable contact is also displaced into contact with hazard warning fixed contacts, turning on a hazard switch to energize turn signal lamps in a hazard warning state. When the control lever is displaced in a direction substantially perpendicular to the first direction while in the hazard warning state, a turn switch is turned on, thereby electrically canceling the hazard warning state. The hazard warning state is thus automatically canceled upon switching from the hazard warning state to a direction indicating state.

Abstract: A constant-pressure operating valve is provided to allow communication between a canister passage connected to a canister and a fuel tank passage connected to a fuel tank and to selectively terminate the communication between them. The constant-pressure operating valve is opened when the internal pressure of the fuel tank exceeds a predetermined value, thereby allowing the fuel vapor in the fuel tank to flow into the canister. Further, when the engine is in operation, the constant-pressure operating valve can be opened, for example, through the action of solenoid, irrespective of the internal pressure of the fuel tank. If the constant-pressure operating valve is opened when the internal pressure of the fuel tank is less than the predetermined value, then the fuel vapor in the fuel tank is drawn into the canister, and so even if the lid of the fuel tank is opened in this condition, the amount of the vapor escaping into the atmosphere is limited.
