Reducing the maximum value of the local average SAR to be absorbed into a human body without forming a short circuit between the conductive plate and the ground conductor is accomplished in a portable radio communication device 1 that includes a circuit board necessary for performing radio communication, a shield case 2 functioning as a ground conductor that shields the circuit board, a conductive plate 3, an antenna feeding portion 4, and an antenna 5. The circuit board, shield case 2, and conductive plate 3 are enclosed by a housing made of nonconductive material. The conductive plate 3 has its both ends along the longitudinal direction electrically opened from the shield case 2.

In a compact portable telephone, a rotational shaft portion of a microphone arm is freely rotatably coupled to the bottom portion of the housing, and it is used in a first state where the housing and the microphone arm are aligned with each other and in a second state where they are intersected to each other at a predetermined angle. A microphone and a helical antenna are contained in the microphone arm, and the length of the microphone arm is set so that the helical antenna is located at a position higher than the upper surface of the housing in the state where the microphone arm is aligned with the housing, thereby avoiding effecting the antenna by the ground conductor and the shield case of the circuit board in the housing.

This invention provides a composite reverse osmosis membrane having a polyamide type skin layer whose average surface roughness is at least 55 nm, and the polyamide type skin layer comprises the reaction product of a compound having amino groups and polyfunctional acid halide compound having acid halide groups. The composite reverse osmosis membrane of this invention is superior in salt rejection and water permeability. A polymer film is formed on a supporting film by contacting a solution containing e.g., m-phenylenediamine with a porous polysulfone supporting film so as to form a layer of the solution on the supporting film, then contacting the film with a solution of trimesic acid chloride and holding the film in a hot air dryer so that a polymer film is formed on the supporting film. The surface of the polyamide type skin layer can also be treated with quaternary ammonium salt and coated with a crosslinked layer of an organic polymer having positively-charged groups. Raw liquid is transmitted from a raw liquid tank to a membrane module for the first stage through a first transmission pump, and the first stage of reverse osmosis treatment is carried out. The composite reverse osmosis membrane coated with the crosslinked layer is used when another reverse osmosis treatment is carried out by using another membrane module for the second stage.

摘要:
An integrated circuit device includes a barrier layer as an underlying layer for a wiring conductor layer. The barrier layer is formed of titanium oxide-titanium nitride or titanium nitride or composite layers of titanium, 2-titanium nitride and titanium nitride. The barrier layer may contain oxygen or carbon. A method of manufacturing an integrated circuit device includes steps of introducing a gas to the vicinity of a substrate disposed within a vacuum chamber, and forming a titanium oxide-titanium nitride thin film or titanium nitride film or the composite film by depositing titanium in vapor phase by using a cluster-type ion source while irradiating the substrate with nitrogen ions. A thin film forming apparatus comprises a cluster type ion source and a gas ion source. The cluster type ion source includes a vacuum chamber maintained at a predetermined vacuum level, a substrate disposed within the vacuum chamber, a gas introducing pipe for introducing gas to the vicinity of the substrate, a vapor generating source for ejecting a vapor of a material for deposition toward the substrate and producing vapor or cluster of the material, an ionizing electrode for ionizing a part of the vapor or clusters, and an accelerating electrode for controllably accelerating the ionized vapors or ionized clusters to thereby transport them to the substrate together with vapors or clusters of the material which are not ionized. The gas ion source includes a nitrogen gas introducing pipe disposed within the vacuum chamber, a gas ionizing electrode for ionizing a nitrogen gas, and an accelerating electrode for controllably accelerating nitrogen ions resulting from ionization by the gas ionizing electrode. Fine contact holes having a high aspect ratio can satisfactorily be coated with a wiring conductor film.
