    • A control system for an electromagnetic valve having a valve element, a pair of solenoids opposed to each other and disposed to drive the valve element in respective directions opposite to each other and between a first extreme position and a second extreme position, and a spring interposed between the solenoids, for biasing the valve element toward a neutral position intermediate between the first and second extreme positions. The solenoids are controlled such that when the valve element is to start moving from one of the first and second extreme positions toward the other extreme position, energization of a corresponding one of the solenoids is terminated, and energization of the other solenoid is started when a predetermined delay time period elapses from the termination of the corresponding one solenoid. The solenoids are also controlled such that they are both energized over a predetermined lap time period during movement of the valve element from one of the first and second extreme positions toward the other extreme position.

    • The operation of an electronic appliance, such as a cassette tape deck, is controlled completely or partially by switch operation. The appliance includes a memory for storage of control information, setting devices, such as switches, for entering the control information, a memory lock or latch for controlling the operating state of the appliance based on the control information supplied from the memory or from the setting devices to the memory lock, and for locking the appliance into such operating state, a display arrangement adapted for display of the setting information and for display of the information in the memory lock, and a setting change display indicator. The setting information stored in the memory can be checked by actuating a check switch, which causes the setting information stored in the memory to be displayed without affecting the operating state in which the appliance is locked. When the operating state is changed by a setting operation while the information previously stored in the memory has been transferred to the memory lock to control the operating state of the appliance, so that the contents of the memory lock (i.e., the operating state in which the appliance is locked) are not coincident with the corresponding information stored in the memory, the fact of such change is displayed on the setting change display indicator. This notifies an operator that the information is being changed, and assists the operator in avoiding unintentional errors.

    • A connector is provided to securely prevent a partial connection while enabling a smooth connection with a mating connector without forcibly turning the mating connector aside. At the front end of the left and right side surfaces of a female housing 1, a pair of spring contact portions 14 laterally symmetrically project in the middle with respect to the height direction of the female housing 1. In the middle of left and right side walls of a receptacle 9 of a male housing 2 with respect to its height direction, a pair of spring accommodating portions 16 in the form of grooves into which the spring contact portions 14 are fittable are formed, and compression coil springs 29 are accommodated therein. When being pushed into the receptacle 9, the female housing 1 is subjected to the reaction forces of the compression coil springs 29. Here, since the pair of compression springs are arranged on the opposite side and in the middle of the receptacle with respect to its height direction, the reaction forces thereof do not turn into such moment forces as to incline the male housing 2. Therefore, the female housing 1 can be inserted into the receptacle without being forcibly turned aside.
