摘要： A push button switch 1 is so constructed as to disengage the movable contacts 55b, 56b from the fixed contacts 55a, 56a through operation of the push button 2 held in the switch case 3. A first leaf spring 550 is provided in the switch case 3 to act as an opening-biasing means to bias the movable contacts 55b, 56b away from the fixed contacts 55a, 56a. The movable contact 55b is disposed at an end of the first leaf spring 550 and adapted to engage with and disengage from the fixed contact 55a. The first leaf spring 550 is adapted to be at a position where the movable contact 55b is open relative to and disengaged from the fixed contact 55a at zero displacement of the first leaf spring 550.

摘要： When an initial position of an enabling switch is given as a first position (301), a position of the enabling switch in which a movable member is most pressed is given as a third position (303), and a rising start position of a maximum rise of a load is given as a second position (302), the rising start position being between the first position (301) and the third position (303), a minor peak (341) of the load appears between the first position (301) and the second position (302). An ON switching position (311) is between a falling start position (323) of the minor peak (341) and the second position (302). A maximum load during the minor peak (341) is greater than or equal to the load in the ON switching position (311) and less than or equal to the load in an OFF switching position (312).

摘要： To prevent incoincidence of contacts, a safety switch switches the contacts by cooperation of an actuator and a switch body. The switch body includes an operating cam and a locking cam that rotate due to insertion of the actuator, an operating rod that switches the contact according to rotation of the operating cam, and a locking lever that is movable toward and away from the locking cam such that the locking lever takes a lock position in which it locks rotation of the locking cam and an unlock position in which it unlocks rotation of the locking cam. The locking lever includes a bulge protruding toward the locking cam. A cam contact surface of the locking lever contacts the locking cam when the actuator moves in a drawing-out direction in an intermediate position between the lock position and the unlock position.

摘要： A door lock apparatus with safety switch capable of assuredly locking a door is provided.A coupling member is pivotally moved about a pivotal shaft by a closing operation by way of a rotary handle, thereby bringing an engaging portion thereof into engagement with a fixing member, so that a protective door is inhibited from moving in two directions of arrows X, Y including a moving direction of the protective door. Whether the protective door is of a slide type or a pivot type, the protective door is assuredly locked in a closed state because the protective door is inhibited from moving in the two directions including the moving direction thereof. Further, if an operation mistake or the like is made to forcibly open the protective door, the force for opening the protective door is not directly applied to the switch body or the actuator. Hence, a safety switch may achieve an increased in durability.

摘要： A fine bubble-containing liquid generating apparatus includes a generator including a mixing nozzle for leading in gas and pressurized liquid and a fine-bubble generating nozzle for discharging liquid that contains fine bubbles of the led-in gas, a circulation passage for returning liquid discharged from the fine-bubble generating nozzle to the mixing nozzle in a state in which the liquid is isolated from outside air, an extraction part for extracting, as a fine-bubble containing liquid, part of liquid circulating through the generator and the circulation passage, and a replenisher for replenishing the circulation passage with liquid to maintain the amount of liquid circulating through the generator and the circulation passage. With this configuration, it is possible to continuously generate a fine-bubble containing liquid that contains a high density of fine bubbles.

摘要： Initial liquid containing fine bubbles is produced by mixing water and air (step S11). Fine bubbles have diameters of less than 1 μm. The density of bubbles in the initial liquid is measured (step S13), and when the measured density is less than a target density (step S14), the initial liquid is heated and reduced in pressure so that the liquid is vaporized (step S15). As a volume of the liquid decreases, the density of fine bubbles increases, and high-density fine bubble-containing liquid is easily obtained. Alternatively, by increasing the density of fine bubbles in the initial liquid with using a filter that does not pass all fine bubbles, high-density fine bubble-containing liquid is easily acquired (step S15). When the density of bubbles in the initial liquid is greater than the target density, the initial liquid is diluted (step S16).

摘要： A safety switch is improved by the feature of staying in an open position in the event of breakage of a working rod or breakage or dropout of an operation portion and having a simple structure facilitating size reduction. Even if a rotary shaft is released from a supported state in an operation portion because an operating force of an operation or the number of operations of extracting an actuator from the operation portion exceeds a breakage tolerance, a working rod is permitted to move in an urging direction of a coil spring and is assuredly moved to the operation portion. Therefore, a switch can be assuredly set to an open position and, hence, the safety switch can achieve the safety improvement.

摘要： A functional element is prevented from breakdown and deterioration because of mounting and demounting of the functional element immediately after cut-off of driving power from a constant-current power supply or during supply of the driving power.An electric circuit is configured to electrically connect a constant-current power supply 1 having a capacitance between an output terminal and a reference potential terminal and a detachable functional element 2 to each other. The electric circuit has an element breakdown prevention circuit 10 having a first circuit terminal connected to an output terminal of the constant-current power supply 1 through the functional element 2, and a second circuit terminal connected to the reference potential terminal of the constant-current power supply 1 through the functional element 2. The element breakdown prevention circuit 10 increases an impedance between the circuit terminals to a disconnected state impedance in response to a transition from a connected state, in which the functional element 2 is mounted, to a disconnected state, in which the functional element 2 is removed. The element breakdown prevention circuit 10 decreases the impedance between the circuit terminals to a connected-state impedance in response to a connection state transition.
