In a disposable wearing article, and area of a rear waist region in which a core is present is divided into a first area and a second area. The second area is formed in its transversely middle zone with a through-hole extending through the core. A transverse fiexural stiffness of the core lying in the second area is lower than a transverse flexural stiffness of the core lying in the crotch region and the first area. Proximal portions of leak-barrier sheets and longitudinal ends of elastic members are in the first area. The first area lies above the crotch region in a thickness direction of the article and the second area forms a barrier and a pocket.

The invention relates to a clutch pipe connector which comprises two pipe bodies. One pipe body is fixedly connected with a fluid source object through threads. The other pipe body is fixedly connected with a fluid feeding object through threads. When the two objects get more close to the two pipe bodies in a certain coaxial range, one pipe body is inserted into the other pipe body, channels in the two pipe bodies are communicated automatically, and one object can provide pressure fluid for the other object. When the two objects are separated from each other by a certain distance, the two pipe bodies are separated along with the objects, the fluid channels in the pipe bodies are sealed respectively, and the distance between the two separated objects is not limited. The clutch pipe connector is small in size, compact in structure, a fixing soft pipe does not need to be hung, the inner channels are large, damping is low, high-flow-speed pressure loss is small, an azimuth error compensation function is achieved, when the tow pipe bodies get close to be in a certain coaxiality position error range, the fluid channels can be reliably connected and disconnected, leakage cannot happen, and the clutch pipe connector can be used in any field.

The electric contact upper panel is provided at a right side thereof with a locking member linked with a brake connecting rod which is linked with a brake plate. The brake plate is located at a lower right side of the locking member. Below the brake plate are disposed an electromagnet pole shoe, an electromagnet coil, and an electromagnet core. The test button protective cap is provided with a test button having a test electric contact.

A multi layered sanitary pad having a unique shape and design for snug fit, increased absorption, comfort, obscurity and enhanced leak prevention that includes a body made up of embossed fleece layers. The upper surface of the sanitary pad includes a central protrusion extending longitudinally and laterally from end to end and side to side, the cross-shaped protrusion including additional cotton wadding, for increased absorption and leak prevention for extended wear. The top surface protrusion is shaped and sized to slightly penetrate the vaginal opening to ensure a snug comfortable fit to increase absorption and enhance leakage prevention along with extended wear. The top surface includes (4) recessed portions surrounding the central protrusion area, for a snug fit, additional absorption, leakage prevention and comfort.

A vehicle air-conditioning device includes an inside / outside air case that selectively sends outside air, which is air outside of a vehicle, and inside air, which is air that circulates inside the vehicle, into a blower casing. An opening end surface of the inside / outside air case that is connected to an additional duct includes a sealing surface. The sealing surface includes a recessed portion, into which a protruding portion is fitted, formed in an end portion of the additional duct. Accordingly, it is possible to directly connect the inside / outside air case to the vehicle outside-air inlet without using the additional duct. Conversely, the vehicle outside-air inlet and the inside / outside air case can be connected to each other via the additional duct when the additional duct is used.

The invention relates to a brewing unit (1) for sequentially preparing beverages from at least two capsules. The water supply device of the only water outlet unit (3) of the base (2). The capsule holder (2) and the water outlet unit (3) can move relative to each other, so that the water outlet unit (3) can be placed or in a first position to effectively connect with the first capsule holder (3). The merger is in operative engagement with said second capsule receptacle (3) in a second position.

Accurate, dependable methods for analyzing operational parameters of subsea control systems and diagnosis / prediction of failures are provided, in particular, methods for detection of leaking and / or clogging in hydraulic control system using recorded pressure signals and evaluating response communication strength (signal amplitude) of field equipment from, for example, subsea control systems. Prediction of failure(s) allows an opportunity to prepare for intervention to minimize the impact of failure before failure occurs, for example, by ordering equipment, tools and / or scheduling an intervention vessel. Similarly, diagnosing a failure drastically shortens the intervention time.

The invention discloses a hydraulic flexible cable cutting knife, which comprises a control valve, a seawater or fresh water hydraulic cylinder and a shear movement mechanism which are connected in order, wherein the control valve controls the hydraulic cylinder to extend and retract; the hydraulic cylinder drives the shear movement mechanism to open and close by extending and retracting so as torealize shearing; the shear movement mechanism adopts a connecting rod-slide block mechanism; a slide block guide rail is integrated with the cylinder body into a whole, which has the characteristicsof compact structure and high rigidity; a reversing valve is designed to have a three-position four-way structure; a contact mode of a valve plug and a valve seat of the reversing valve adopts a floating structure; and under the action of spring pressure, the valve plug and the valve seat always contact reliably, and a clearance after abrasion can be automatically compensated so as to greatly improve the reliability and service life of a seal. The hydraulic flexible cable cutting knife takes seawater or fresh water as a working medium, has the characteristics of high efficiency, large operational depth, convenient operation and good environmental compatability, and can be widely used for underwater and land shearing operation.

A leakproof arrangement of a chocolate fountain includes a leakproof device tightly fastened within the through hole of the basin. The leakproof device has i) a base sealed to the periphery of the through hole of the basin; ii) a plurality of support frames disposed around the base; and iii) a shaft sleeve disposed at the center of the base, the joint between the shaft sleeve and the base being tightly sealed without any gaps, the height h2 of the shaft sleeve being greater than the maximal chocolate level h1, the connection end at the top of the shaft sleeve rising above the height h2 of the shaft sleeve. In this way, the melted chocolate will never flow over the shaft sleeve such that downward leakage may be avoided. As a result, the leakage of the melted chocolate is prevented, thereby ensuring a smooth operation of the transmission element as well as a prolonged service life.
