A stretchable raised electrode having a stretch property that can be used as a biological electrode for collecting biological signals while being pressed against a body is provided, and a method of manufacturing the stretchable raised electrode is provided. This raised electrode is a raised electrode formed by raising a surface of a sheet material having the stretch property. This raised electrode includes: a resin layer configured to be stretchable to follow the surface of the sheet material; and a plurality of conductive fibers each having an inserted portion, one end of which is inserted into the resin layer. The conductive fibers that are adjacent to one another are electrically in contact with one another at non-inserted portions into the resin layer, and the conductive fibers are formed in the resin layer so as to have such a density as causing an in-plane isotropic electric conductivity of an electrode region of the sheet material in which the conductive fibers are formed. This raised electrode can be obtained by an electrostatic spraying method.

Stretchable raised electrode and method of manufacturing thereof

Provided is an air-permeable sheet () to be used in a state of being interposed between a suction stage () and an air-impermeable substrate () when printing is performed by a sheet-fed method on the surface of the substrate () fixed by suction to the suction stage (), the air-permeable sheet capable of printing a desired printing pattern on the surface of the substrate with high accuracy. The air-permeable sheet () includes a non-woven fabric layer () and a support layer () constituted by a woven fabric or knitted fabric.

A container-type data center enabling transportation while having IT equipment stored therein, Vibration isolation table units laid on a floor surface in a storage unit of a container are composed of a lower plate and an upper plate, and multiple spring vibration isolators are fixed between the plates. The lower plates of adjacent vibration isolation table units are fixed via a lower fixing member, and upper palates of adjacent units are fixed via an upper fixing member. Two racks are loaded per single vibration isolation table unit. By adopting this configuration, even when shock is applied on the container, the vibration transmitted from the container can be absorbed by the spring vibration isolator. Thus, even when the container is transported with the IT equipment and the like stored in the rack, it becomes possible to prevent the occurrence of failures such as fluctuation of the IT equipment, fall of the equipment by vibration, or detachment of internal components.

Container-type data center

A container-type data center is provided, which can be transported while having outdoor units of an air conditioning facility installed therein, and having an enhanced cooling effect. A partition panelis provided for separating a containerinto an IT equipment accommodation chamberand an outdoor unit installation chamber, and on both ends of the panel are provided pillar sectionsandfor the partition panel. The length-direction dimension of the outdoor unit installation chamberis within the range of 1.6 to 2 meters, which can be selected arbitrarily according to the size of the outdoor unitsthrough. The outdoor unitsthroughare arranged so that their air discharge openings face the outer side in the width direction of the container. Regarding the outdoor unitsthrough, it is possible to set up an angle steel rack and stack two outdoor units vertically. According to this configuration, the container-type data center can be transported while having the outdoor units installed therein, and can exert sufficient cooling ability, which had been insufficient due to the small number of outdoor units installable in the prior art container-type data center.

The present invention provides a container-type data center having an air conditioning facility, which enables to effectively cool IT equipment by applying the arrangement to an existing container. A system ceilingis attached to a ceiling surfaceto send out cooling air to a cooling areafrom a ventof an indoor unitof an air conditioning device disposed in a container, and a draft air duct is defined by the system ceiling, a down-walland the ceiling surface. A vinyl curtainis provided on an upper portion of a rackso as to prevent cooling air having reached the cooling areafrom flowing out to a heat exhaust areawithout passing through the rackloading the IT equipment, and a vinyl curtainin a form of a shop curtain is disposed at an area used as a path for operators entering the cooling area. According to this arrangement, all the cooling air sent to the cooling areais discharged through rackslading IT equipments to the heat exhaust area, enhancing the effect of cooling the IT equipment loaded in the racks
