An operational air conditioning mode is allowed to set to a temperature uniformization mode and a spot air conditioning mode, and is selectively switched between these modes automatically by a control means (53) or manually. In such an embodiment, a comfortably air-conditioned state is obtained in all the areas of a space to be air-conditioned W during air conditioning performed in the temperature uniformization mode, and the comfort is ensured by intensively air-conditioning the surroundings of a person during air conditioning performed in the spot air conditioning mode. At the same time, since an unnecessary air conditioning is not provided to a region without the presence of a person, energy conservation is improved, for example, and thus the comfort of air conditioning and energy conservation are both achieved.

The antenna coil has a first opening and an auxiliary coil. The auxiliary coil has a second opening which has an opening area smaller than the first opening. The auxiliary coil is insulated and isolated from the antenna coil, and arranged so that the second opening is opposed to a part of the first opening when viewed from a direction orthogonal to a surface of the support substrate.

A locking tree cap for use on a subsea tree. The tree cap may be installed and retrieved using a remote operated vehicle. The tree cap may include deflectable collet fingers that lock the tree cap to a tree spool. The deflectable collet fingers may be adapted, such as with enlarged heads, to extend into recesses of the tree spool when the tree cap has been landed on the tree spool. The tree cap may be locked onto a tree spool before energizing sealing members within the bores of the subsea tree, thereby protecting the sealing members from damage during the installation of the tree cap onto the tree spool. The tree cap may include soft landing means such as a plastic cap, on the end of stabs to protect the sealing members as the tree cap is landed. The tree cap may include a secondary locking mechanism used to further secure the tree cap to the tree spool.

Disclosed is a sanitary napkin which is allowed to quickly absorb menstrual blood and also effective in preventing absorbed menstrual blood from returning to the skin-side surface under pressure and in concealing the color of absorbed menstrual blood from the outside. Between a liquid absorbent layer and a topsheet formed of a resin film having a large number of liquid passage apertures, there is disposed a barrier layer formed of a resin film having a large number of liquid passage apertures. The barrier layer is composed of a plurality of strip-shaped elements, and liquid passage regions are defined between adjacent elements of the barrier layer. After passing through the liquid passage apertures of the topsheet, menstrual blood tends to be absorbed by the liquid absorbent layer through the liquid passage regions. The barrier layer functions to prevent liquid return and conceal the color of menstrual blood.

The invention discloses a steel mesh which is provided with a plurality of holes, wherein at least one protrusion is arranged in one hole. The invention also discloses a PCB (Printed Circuit Board) which is provided with a plurality of bonding pads, wherein the bonding pads are provided with at least one notch, and the shape of each hole of the steel mesh is matched with the shape of each bonding pad. Limited by the protrusions in the steel mesh holes, the quantity of dipped solder paste is reduced to achieve the aim of reducing the consumption of the solder paste at the bottom of an element or a device, the internal flowing of the solder paste is lessened by the reduced consumption of the solder paste so that the surface tension of the element or the device is balanced to avoid adverse phenomena, such as tin wires and tombstones generated at the bottom of the element or the device, the rotating position offset of the element or the device during the reflow, and the like.

A carrier structure for fabricating a stacked-type semiconductor device includes: a lower carrier that has laminated thin plates and has first openings for mounting first semiconductor packages thereon; and an upper carrier having second openings for mounting second semiconductor packages on the first semiconductor packages. The lower carrier composed of the laminated thin plates realizes an even plate thickness and reduces warps because stress is distributed to the thin plates. This results in an improved production yield. A pattern of the openings in the thin plates of the lower carrier may be formed by etching or electric discharging. The openings thus formed have reduced warps and burrs.
