Abstract: An on-press development type lithographic printing plate precursor includes a support, and an image-recording layer on the support, in which the image-recording layer contains an infrared absorber, a polymerization initiator, a polymerizable compound, and at least one compound selected from the group consisting of a compound represented by Formula (1) and a compound represented by Formula (2) (in Formulae (1) and (2), Ra1 and Ra2 represent an alkyl group, Rb1 and Rb3 represent an alkyl group, Rb2 and Rb4 represent an alkyl group, and EWG's each independently represent a hydrogen atom or an electron-withdrawing group, provided that at least one of the four EWG's in Formula (1) represents an electron-withdrawing group).

Abstract: A switch device has an operating knob held at a neutral position by a slider. The operating knob includes an articular recess swingably provided over a base body. A spring and the slider are set in a rectangular pipe which is a part of the base body. Guide pins at the outer end portion of the slider are loosely engaged with slide grooves formed in guide-pin guiding portions. When the slider, being urged by the spring, is in engagement with the articular recess, it holds the operating knob at the neutral position so that the operating knob is allowed to swing about the guide pins.

Abstract: A rotary direction detecting sensor for use on an automobile includes a pair of switching means provided radially from an axis of a steering shaft, and angularly spaced from each other at a predetermined angle about the axis. A first rotary member and a second rotary member are provided around the steering shaft, one of the rotary members being rotated in accordance with the rotation of the shaft and the other of them being limited in rotation to a substantially half angle of the angle between the switching means. In response to one direction of the rotation of the shaft, one of the switching means is selected to actuate blinking of one turn indicator lamp whereas the other of the switching means is held at its original deactivated position. On the other hand, in response to the other direction of the rotation of the shaft, the other of the switching means is selected for its operation.

Abstract: A switch assembly in which a lever rotates a separate rotary member to operate a first electrical switch and the lever pivots within the rotary member to operate a second electrical switch. The rotating member is held at a first position and a second position when the rotary member is turned. A solenoid is linked to a cam that restores the lever to a neutral position between the first and second positions. A return mechanism returns the pivoting member to its original position when the lever is released.

Abstract: There is provided a dimmer passing device for a headlamp of a vehicle having a light switch which drives a light relay when it is on, a momentary control switch which activates the light relay when it is on, a latch circuit which alternately turns on and off an internal switching element in response to the on state of the momentary control switch, and a dimmer relay which causes the light relay to energize a low beam of the headlamp when the internal switching element is turned off and which causes the light relay to energize a high beam of the headlamp when the internal switching element is turned on.

Abstract: A manually operated mode-selecting valve device allowing pressurized air to be transmitted to a plurality of working agents so as to actuate them simultaneously with the movement of a single valve medium upon operating a corresponding single actuator is disclosed. The operational force required is reduced to such a point as that merely needed to move a single number of the valve medium. The valve medium serves as an air-passage way in cooperation with an air-passage forming medium, thereby rendering reducing the number of part components together with structural simplification.

Abstract: A switch structure comprising an actuator reciprocally movably mounted on a casing so as to control a contact structure, a cardio-shaped grooved cam provided with the actuator, a wire spring secured at one end to the casing and disposed at other free end in the grooved cam, a locker structure which alternatively holds the actuator at a return position or at an operative position by selectively engaging the free end of the wire spring with the first or second engagement portions each provided with the grooved cam, and an electromagnetic solenoid which releases the free end of the wire spring from the second engagement portion.

Abstract: A switching device comprises a movable member which makes the first switch turn to an opposite phase at the first thrust-in position and makes the second switch turn to an opposite phase at the second thrust-in position, a first locking means which locks the movable member at the first thrust-in position, a second locking means comprising a torsion coil spring engaging member and a heart type cam recess on which the engaging member slides, which locks the movable member at the second thrust-in position, and a reset member which releases the movable member from the locking state. The first and second switches are selectable to set and can be alternatively operated only by repeated thrust-operation.

Abstract: An improved rotary direction detecting sensor to be used for a vehicle. It includes a stationary member including a cylindrical extension, a movable member fitted on a rotor and rotatable in the same direction associated with the rotor, the rotor being rotatably fitted to the stationary member on its cylindrical extension, while the stationary member is kept unrotatable irrespective of the rotation of the rotor, and a follower member interposed between the stationary member and the movable member. The follower member has a cut-out engaged with a corresponding projection formed on the movable member to delay the rotation of the follower member for a predetermined angle with respect to the rotation of the movable member. Both the movable member and follower member are provided with separate connecting contacts, while the stationary member is provided with a group of contacts selectively contacted by the connecting contacts depending on the rotary direction of the rotor.
