Abstract: A closed type device having excellent waterproofness and dustproofness, capable of preventing the entry of a corrosive gas, and having humidity conditioning function. In the heat radiating structure of the device (10), a ventilation hole (13) is formed in a part of the casing of the device formed of a casing body (11) and a door (12), and a composite sheet (14) formed by overlapping a carbon sheet in which the layer of activated carbon is held by permeable non-woven fabric with a fine-hole sheet having air permeability, waterproofness and dustproofness is fitted to the casing with the fine-hole sheet facing outward so as to cover the ventilation hole (13).

Abstract: In a housing having a sealing structure providing an electromagnetic wave shielding function and a waterproof function between first and second housing components (1, 2) which define a space therebetween, the sealing structure includes a groove portion (12) made in the first housing component to extend around the space, a first seal member (13) formed by being directly applied into the groove portion, a second seal member (14) formed by being applied onto the first seal member, and a pressing portion (16) formed on the second housing component to correspond to the groove portion. The first seal member has relatively low hardness to be compressible. The second seal member has relatively high hardness, flexibility, and conductivity. When the first and second housing component are combined to each other, the pressing portion pressingly deforms the second seal member so as to be brought into surface contact with the second seal member. The first and second housing component are made of magnetic metal.

Abstract: A mount shelf for an electronic circuit board, includes a body; a first guide which is supported by the body and has a first guide plane; a second guide which is supported by the body and has a second guide plane; a third guide which is supported by the body and has a third guide plane; and a fourth guide which is supported by the body and has a fourth guide plane. The first guide plane and the second guide plane respectively have first contact planes on which a first end plane portion of one straight first edge region of an electronic circuit board can be contact at a same time. The third guide plane and the fourth guide plane respectively have second contact planes on which a second end plane portion of another straight second edge region of the electronic circuit board can be contact at the same time. The first guide and the second guide are separated to a degree of a width in a direction in which the first edge region or the second edge region of the electronic circuit board is extended.

Abstract: The fastening torque control tool for a fastening device herein includes a base portion which is fixed onto a head portion of the fastening device in a way that restricts relative rotation around the device's axis. The tool has an operational portion which is integrally provided with the base portion on the same axis. The operational portion is fixed into a fastening instrument to turn the fastening device in a way that restricts relative rotation around the axis. The control tool also contains a separating portion for separating the operational portion from the base portion when a fastening torque, which is applied to the operational portion, reaches a predetermined level. The separating portion is formed between the base portion and the operational portion.

Abstract: A hermetic type outdoor equipment such as radio relay equipment is provided with a respiratory structure (8) having a minute-hole sheet (5) applied to a respiratory hole (4) of a case (3) of the equipment, and capillary members (9) implanted outwardly on a surface of the minute-hole sheet (5). The equipment case (3) is composed of a lower housing (2) and an upper housing (1) hermetically engaged with the lower housing (2), and the respiratory hole (4) is formed through the lower housing (2). The minute-hole sheet (5) is disposed at the inner surface side of the case (3), and the capillary members (9) extend outwardly within the respiratory hole (4). A plate (6) having an opening (6a) at a position corresponding to the respiratory hole (4) and superimposed to the minute-hole sheet (5) and the minute-hole sheet (5) is fixed to the lower housing (2) of the case (3) by screws (7).

Abstract: An agent for inducing flower bud formation in plants comprising an unsaturated fatty acid having an oxo group and a hydroxy group, a hydroperoxy group, or an oxo group, a hydroxy group, and a hydroperoxy group; a method for preparing said agent for inducing flower bud formation; and, a method for inducing flower bud formation using said agent for inducing flower bud formation are provided.

Abstract: A cooling apparatus for cooling a housing includes a heat radiating member, a heat radiating unit, and a heat absorbing unit. The heat radiating member is provided in the housing and has a path formed to have an opening portion in an upper portion of the housing. The heat radiating unit is provided in at least a part of a surface of the path of the heat radiating member. The heat absorbing unit is provided in a peripheral portion of the heat radiating member such that heat radiated from the heat radiating unit is removed via the path from the opening portion of the heat radiating member by a chimney effect.

Abstract: The present invention relates to an opening/closing hinge construction for an electronic and electrical equipment housing. By improving the hinge construction so that the hinge construction between a body case and body cover is contained within the housing, the housing is prevented from being large-sized and the assembling property is enhanced, whereby the whole manufacturing cost including the assembly cost is reduced. The construction is such as to open and close the body case forming an equipment housing by the body cover of cover member, and a hinge sheet having flexibility formed into a sheet form is used for a hinge connection portion. One end of the hinge sheet is fixed to the interior of the body case by using hinge bosses and set screws as a fixed locking end, and the other end is fixed to the inside of the body cover as a movable locking end.

Abstract: An admixture for cement compositions containing tetrahydroborate, and cement composition containing a tetrahydroborate admixture made of salt borohydride, cement, aggregate and water. Since tetrahydroborate has the expansion effect hardly influenced by temperature, expansion amount is easily controlled. Since cells generated by foaming are fine, a hardened body with the excellent resistance to freezing and thawing can be obtained.

Abstract: A gob distributing apparatus having a gob feeder, a scoop for selectively connecting the feeder to desired immovable chutes of a bottle making machine, and an actuator of the scoop. The scoop has rollers which are provided on the scoop and a rotatable spiral cam which is engaged by the rollers, so that the rotation of the cam causes the scoop to rotate in order to selectively connect the chutes and the feeder.
