Abstract: A solenoid valve with protective cap (10) having electrical connection elements (11, 13) attached to the cap fits only the electromagnet (2) of a solenoid valve (1). A cavity (12) situated in the cap makes it possible to add on circuit band unit (20) providing circuits which complement the solenoid valve but vary from user to user. Cable connection elements, elements for visual indication of the functional state, delay circuits, interference-suppressing circuits, intrinsic safety circuits, circuits for detecting the position of the moving core, circuits for detecting the presence of fluid, logical indexing circuits etc. may be mentioned as examples of circuit elements which complement the solenoid valve. The solenoid valve also comprises connection elements (18) which permit a rational and cableless electrical link between at least two solenoid valves.

Abstract: A door locking handle assembly of pull-out and side-swinging lever-action type, in which the entire length of a casing 1 is minimized while an effective length of a handle 18 is obtained sufficiently to improve the assembly in operability. A catch plate 36 is fixed to a locking shaft 11 mounted in a cylindrical portion 2 of the casing 1. The handle 18 received in a front concave 3 of the casing 1 is pivoted to the shaft 11 through a first pivot 37, and swingably urged by a spring 38 to project outwardly. In the front concave portion 3 of the casing 1, a push button 30 is pivoted to a button casing 24 through a second pivot 39, and urged by a position-keeping spring 40 to have its engaging-hook portion 31 engaged with an engaging projection 25 of the button casing 24. A rotor 42 of a lock unit 41 fixedly embedded in the handle 18 is interlocked with a lock plate 45 engaging with an engaging projection 26 of the button casing 24.

Abstract: A door locking handle assembly of a pull-out and side-swinging lever-action type, includes a casing (4) having a rotatable locking shaft (12) and a pivotable handle (19). When the handle (19) is pushed into a front concave portion (6) of the casing (4), the handle (19) can be held in its retracted position without fail. A push button (27) is pivotally mounted on a front-end portion of the handle (19) so that when the push button (27) is swingably depressed, the handle (19) can project outwardly from the front concave portion (6) of the casing (4). The thus projected handle (19) is side-swing to have a catch plate (11) of a locking shaft (12) disengaged from its locking position.

Abstract: Swingable handle assembly comprises a push button 3 operated with a minimum of effort; an arm 16 in a rear surface of the button 3 obliquely projects upward and outward therefrom; a handle 2 is in an elongated hole 9 of a casing 1 and vertically adjacent to the button 3 in the hole 9; the handle 2 has it supper-end portion pivoted to the casing 1 through a pivot 17 through which a spring 5 for biasing the handle 2 toward its projecting position is pivoted to the casing 1; the arm 16 has its front-end portion pivoted to the casing 1 through a pivot 8; a return spring 6 is interposed between the button 3 and the casing 1; provided in a side surface of the button 3 is a projection 11 abutting on a rear surface of an edge portion of the hole 9; the handle 2 has a front corner of its lower-end portion formed into a shoulder 12 abutting against an upper-end projecting edge portion 10 of the button 3.

Abstract: A door locking handle assembly of a pull-out and side-swinging lever-action type, in which the entire length of a casing (1) is minimized while an effective length of a handle (18) is sufficiently obtained to improve the assembly in operability. A catch plate (50) is fixed to a locking shaft (11) mounted in a cylindrical portion (2) of the casing (1). The handle (18) is received in a front concave portion (3) of the casing (1) and is pivoted to the shaft (11) through a cross pivot (40). A latch element (25) engaged with and disengaged from a hook (19) of the handle (18) is received in a latch casing (29). The element (25) is interlocked with a push button (37) in a depressing operation thereof to linearly move so that the handle (18) locked up in the casing (1) is released to project from the casing (1) by a biasing spring (41).

Abstract: A device for displaying an image delivered in particular by a radar on a screen of a television monitor associated with a videographic memory the contents of which are controlled by a control assembly for the control of the display and reception of the image to be displayed, the control assembly functions in conjunction with an after glow processor for processing the contents of certain zones of the videographic memory in accordance with a given law a mathematical treatment formula for producing a pseudo-after glow phenomenon of certain points of the radar image displayed on the screen.

Abstract: A hermetically-sealed handle assembly is disclosed. The assembly cuts labor costs and improves the productivity in manufacturing. A back plate 1 has a hole 4 in its central portion, in which 4 a head 3 of a pivot bolt 2 is inserted in a non-rotatable manner. A base plate 5 has a through-hole 7 for receiving therein a threaded shaft 6 of the bolt 2, and is provided with a hole 8 having its hole edge 8a subjected to a burring operation through which the hole edge 8a is passed through a through-hole 24 of the back plate 1 and turned outward behind the plate 1 to have it fixed to the base plate 5. A handle 9 has an axial hole 10 for receiving the threaded shaft 6 therein. A cap nut 11 is threadably engaged with a front end of the bolt 2 through a washer 12. A screw 14 threadably engages with a radial hole 13 of the nut 11, the screw 14 having its front end intensely abutted against a side surface of the threaded shaft 6.

Abstract: A door locking handle assembly of a pull-out and side-swinging lever-action type, includes a casing (4) having a locking shaft (12) pivotally attached to a handle (19), which can be pushed into a casing (4), and locked in its retracted position without fail. A push button (27) is pivoted to a front-end portion of the handle (19) through a pivot (25) passing through an axial hole (50) of the button (27). The hole (50) is obliquely extended and assumes an oval shape. By depressing the pivoted push button (27), the handle (19) swings out of a front concave portion (6) of the casing (4). A catch plate (11) attached to the locking shaft (12) is swingably moved to its unlocking position by side-swinging the handle (19), which has its front-end portion receive a lock unit (31) fixedly in an embedding manner.

Abstract: Latch assembly which is free from unlocking accidents, enjoys smooth operations in locking of a wing element and in engaging of a latch arm with a socket member, and properly covers a gap between the wing element and a stationary frame. The gap is resulted from misalignment in assembling of the wing element and the stationary frame. In the assembly: a lever 3 has its base end pivoted to a base plate 1 through a pivot 4; a latch arm 5 has its base end pivoted to the lever 3 through a pivot 6; a locking plate 10 of the plate 1 has a locking socket 14 which is engaged with and disengaged from a front end of a stop member 13 fixed to a rotor 12 of a lock unit 11; a spring 15 has its coiled portion 16 mounted on the pivot 4 to bias the lever 3 upward; a support 30 carries the member 8 movable along a longitudinal direction of the arm 5; and, a spring 36 biases the member 8 away from the pivot 4.

Abstract: A door locking handle assembly of a pull-out and side-swinging lever-action type, in which the entire length of a casing 1 is minimized while keeping a sufficient effective length of a handle 18 to improve the assembly in operability. A catch plate 36 is fixed to a locking shaft 11 mounted in a cylindrical portion 2 of the casing 1. The handle 18 received in a front concave 3 of the casing 1 is pivoted to the shaft 11 through a cross pivot 37, and swingably urged by a spring 38 to project outwardly. A button casing 24 is fixed to the concave 3. A push button 30 is slidably mounted in a recess 27 of the casing in an insertion manner while horizontally non-slidable therein and urged by a spring 40 to move upward, and has its upper projection 32 engaged with a front hook 20 of the handle 18. A rotor 42 of a lock unit 41 fixedly embedded in the handle 18 is engaged with a lock plate 45 engaging with a projection 26 of the button casing 24 to lock the handle 18 in its retracted position in the casing.
