An actuator of the present invention comprises an operation key 2 to be inserted into a key insertion hole formed in the safety switch, and a base 3. The operation key 2 is held on the base 3 and capable of freely swinging in two orthogonal directions. The actuator also comprises means (e.g. a guide stopper 4 and engagement spaces 34) for selectively restricting the swinging movement of the operation key 2 to either of the two directions.

A push-button switch 5 disposed in a switch case 3 has c-contacts and a normally close contact electrically connected with a terminal block 9 via conductors 39. Leading ends 23 of cores of a cable 7 introduced into the switch case 3 are inserted in insertion holes 49a, 49b formed in the terminal block 9. Screws 53a, 53b mounted to the terminal block 9 are tightened to press the leading ends 23 of the cores against conductive connection portions, on one side, in the insertion holes 49a, 49b, thereby to establish electrical connection.

A push-button switch and a teaching pendant employing the same are provided. The push-button switch ensures that a push button is capable of switching ON/OFF the switch if one of contacts thereof should fail during an operation of the switch. For achieving this object, a switch case 3 contains two c-contacts 9a, 9b each having a snap action configuration and switching mechanisms 11a, 11b for opening/closing the c-contacts 9a, 9b. When a push button 5 is depressed, the switching mechanisms 11a, 11b simultaneously open/close the c-contacts 9a, 9b for turning ON/OFF a push-button switch 1.

In a case where a left-hand push-button switch is ON, a second relay RL2 is electrically de-energized to open a normally close contact RL2-1 of the second relay RL2 so that a relay contact circuit RC is opened. If, in this state, a right-hand push-button switch is shifted to a second OFF state, a normally close contact R3-1 of the right-hand push-button switch is opened. Thus, a third relay RL3 is not electrically de-energized and a first and a second circuits are in cutoff until both the right-hand and the left-hand push-button switches are returned to a first OFF state.

A main lock mechanism and an auxiliary lock mechanism are juxtaposed with a switch body. The main lock mechanism including a switchable portion switchable between Lock position and Unlock position, an operation piece removably mounted to the switchable portion for switching the switchable portion, and a lock body which, when an actuator is inserted, disables or enables the rotation of a drive cam depending upon whether the switchable portion is at Lock position or Unlock position. The auxiliary lock mechanism including a drive portion actuated at transfer of the switchable portion to Lock position, an auxiliary contact alternating between a closed position and an open position depending upon whether the drive portion is non-operative or operative, and an operative portion which maintains the switchable portion at Lock position when the drive portion is non-operative and permits transfer of the switchable portion to Unlock position when the drive portion is operative.
摘要:
A push-button switch provided with a hollow push button, a case supporting it, and a switching mechanism having a first contact disposed within the case and a second contact disposed opposite to the first contact, with one of its ends being inserted into a hole of the push button. Within a hole formed in an inserted section of the switching mechanism, a slide block is provided slidably in a direction crossing the direction in which the push button is pushed. A slope capable of engaging with a slope of the hole of the push button is formed on the slide block. A coil spring (return spring) for energizing a shaft of the switching mechanism so as to abut the push button is provided on the bottom of the case. This configuration enables the push button to take up a first OFF state, an ON state and a second OFF state in order of depression.

The safety switch unit controls the source of power for machinery in accordance with the opening and closing of a room door. The safety switch includes an actuator (2) secured to a door, a cam shaft extending transversely of a direction in which the actuator (2) advances into the switch unit (1), the actuator (2) having a stepped top end in correspondence to which cam plates (13), (14a) and (14b) are provided within the switch unit (1) each capable of independently rotating, these cam plates having start sides (17) and (22) and a single cam follower pin (29) passed therethrough, thus protecting the switch unit (1) against mischievous or malicious operation.

There are provided, together with two microswitches 20 accommodated in a cylindrical compartment 13, a manipulation member 2 which can freely swing about a pivot portion 2a in the directions of arrows A and B, a transmission member 3 which can freely move in reciprocating motion within a specific range between a transmitting position and a non-transmitting position located along a radial direction of an arc which is the trajectory of the swing motion of the manipulation member 2 in the directions of the arrows A and B, a contact member 4 which can freely move in reciprocating motion within a specific range between an exposed position and a retracted position in the directions of arrows E and F, a driven member 5 which can freely move in reciprocating motion in the directions of arrows G and H, and a restricting part 6 fixed at a position opposing the contact member 4. The swing motion of the manipulation member 2 in the direction of the arrow B up to a point where the manipulation member 2 goes into contact with the restricting part 6 is transmitted to the microswitches 20 via the transmission member 3 and the driven member 5, and the swing motion of the manipulation member 2 in the direction of the arrow B is not transmitted to the microswitches 20 after the contact member 4 has gone into contact with the restricting part 6. This arrangement makes it possible to achieve improved operability of an enable switch, enhanced safety with the provision of multiple contact mechanisms, and easier installation of the enable switch on a portable operator panel.

A head related transfer function generation apparatus includes a first input unit that inputs a first head related transfer function generated in a first measurement environment, a second input unit that inputs a second head related transfer function generated in a second measurement environment, and a transform normalization processing unit that normalizes a first gain of the first head related transfer function represented in frequency-axis data with a second gain of the second head related transfer function represented in frequency-axis data and also calculates a square root thereof.

A tubular knitted fabric for clothing has a first stitch and a second stitch smaller than the first stitch. The pattern of the tubular knitted fabric for clothing is obtained by selectively disposing the second stitch in units of one stitch. Selectively driving a sinker of a circular knitting machine controls stitch densities, thereby producing the first stitch and the second stitch smaller than the first stitch. A legwear is formed of this tubular knitted fabric for clothing.
