Abstract: The present invention relates to a gas fuse cock embedded with a flow rate sensor and an automatic gas safety shut-off device having the same, in which a flow rate sensor unit is injection-molded integrally with the gas fuse cock, and the flow rate sensor is mounted to reduce leakage of gas without a separate connecting component, and the present invention provides a gas fuse cock embedded with a flow rate sensor and an automatic gas safety shut-off device having the same, in which the flow rate sensor is directly embedded in a housing of a gas valve without a separate connecting tube, and a connecting portion is eliminated, thereby improving safety against leakage of gas.

Abstract: A fabrication method for a diary or electronic device cover, the fabrication method includes the steps of: disposing an elastic first synthetic resin on a joint panel; disposing a second synthetic resin on the first synthetic resin; disposing a third synthetic resin different from the first synthetic resin and the second synthetic resin in material; joining the first synthetic resin, the second synthetic resin, and the third synthetic resin at a plurality of points; and injecting air into a space between the first synthetic resin and the second synthetic resin to allow the cover to have a bulged surface.

Abstract: A wiper blade having a spoiler-integrated lever assembly. The lever assembly of the wiper blade includes a connector seat to which a connector assembly for connection to a wiper arm is detachably connected. The connector assembly is detachably joined to the connector seat by inserting an insertion protrusion of the connector assembly to an insertion slot of the connector seat and then rotating the connector assembly towards the connector seat and thus bringing snap protrusions of the connector seat into snap-engagement with snap slots of the connector assembly.

Abstract: A wiper blade suitable to six types of wiper arms. A connector assembly of the wiper blade is detachably joined to a lever assembly and is detachably connected to wiper arms having first to sixth coupling units at a distal end respectively. An adaptor of the connector assembly is rotatably attached to the lever assembly. A slide cover of the connector assembly is slidably joined to the adaptor. A side lock cover of the connector assembly is detachably joined to the adaptor. The slide cover is moved to the adaptor in a first movement direction parallel to a longitudinal direction of the lever assembly to cover top contact surfaces of the first to third coupling units. The adaptor is fitted to the fourth coupling unit. The adaptor is connected to the fifth and sixth coupling units by a side pin passing through the side lock cover.

Abstract: A wiper blade having a lever assembly and a spoiler integrated in the lever assembly. The wiper blade has a wiper rubber and the lever assembly holding the wiper rubber and being coupled to a wiper arm. The lever assembly has a plurality of levers, adjacent levers of which are hinge-jointed to each other.

Abstract: A wiper blade suitable to three types of wiper arms. A connector assembly of the wiper blade is detachably connected to wiper arms having first to third coupling units at a distal end respectively. The connector assembly has an adaptor and a slide cover slidably joined to the adaptor. The slide cover is moved to the adaptor in a first movement direction to fix the first to third coupling units to the adaptor and is moved from the adaptor in a second movement direction opposite to the first movement direction to release fixation between the coupling units and the adaptor. The adaptor has a support protrusion supporting support surfaces of the first to third coupling units. The slide cover has a push surface contacting the contact surfaces of the first to third coupling units to push the first to third coupling units towards the support protrusion of the adaptor.

Abstract: A gap control device for a Pilger die assembly of cold Pilger mills.
