摘要:
A variable capacitance element includes a movable element provided above a substrate using supporting portions and support beams so as to be displaced from the substrate. An insulating film and a movable electrode are provided on a conductor facing surface of the movable element. A driving electrode is arranged to displace the movable element, between a signal cutoff position and a signal passage position, whereby a high frequency signal transmitted through a transmission line is cut off or allowed to pass. The insulating film uses compressive stress to warp the movable element and the movable electrode in a direction of warping in a convex form toward the transmission line, and maintains this warping direction.

A semi-solid lubricant composition for transmission elements which is excellent in lubricity, antiwear properties, and energy-saving performance, has high reliability, and is for use as a turbine oil, machine tool oil, metal working oil, plastic working oil, cutting oil, compressor oil, vacuum-pump oil, electrical-contact oil, grease, or machine oil; and a mechanical system provided with the composition. The composition, which reduces the wear of sliding parts of a transmission element, comprises: an amide compound having one or two amide groups and forming a three-dimensional network structure; and a liquid base oil ingredient having a dynamic viscosity at 100° C. of 25 mm2/s or lower and a viscosity index of 120 or higher. The composition contains substantially no ingredients other than the amide compound and liquid base oil ingredient. The mechanical system has a transmission element including sliding parts which are provided with the semi-solid lubricant composition for transmission elements.

A preheat device (160) is provided to execute, before forming bumps (16) to electrode parts (15), a pre-formation temperature control for bonding promotion to promote bonding between the electrode parts and the bumps during bump formation. Metal particles of the electrode parts can be changed to an appropriate state before the bump formation. Phenomenally, a bonding state between the electrode parts and the bumps can be improved as compared with the conventional art. In a further arrangement of the present invention, semiconductor components with bumps can be heated under a bonding strength improvement condition by a bonding stage (316) through controlling the heating by a controller (317).

In a mobile communication system comprising a PBX connected to a mobile communication network through an interface unit and having a semi-public roaming function, a first PBX is connected to a second PBX having the semi-public roaming function with a leased circuit. The first PBX transmits a position registration/call transmission request of a PHS received by itself to a mobile communication network through the second PBX. The second PBX transmits a call reception request addressed to the PHS from the mobile communication network to the PHS through the first PBX.
摘要:
A temporarily saved band value management table for managing temporarily saved band value is provided, as is a band management table for managing empty band value in the storage device of an ATM exchange comprising a storage device, a control device, and the like. The control device selects a corresponding empty band value for a temporarily saved band value when a first camp-on request is received from a terminal, and sets the empty band value to “0.” In addition, the control device adds to the temporarily saved band value a band value released by a break in communication when a camp-on request is registered, and grants permission for communication to the terminal that has issued this camp-on request when the temporarily saved band value is higher than the band value required by a registered camp-on request. The control device determines whether or not a connection request can be accepted on the basis of the empty band value stored in the band management table.
摘要:
The present invention provides a bump bonding method that can prevent bumps from being inappropriately shaped. The bump bonding method comprises forming a gold ball (16) at the tip of a gold wire (1) that is inserted through a capillary (3), lowering the capillary (3) while using a displacement detection sensor to detect the vertical displacement of the capillary (3), detecting the position of that portion of an IC (11) in which an electrode is formed, based on the displacement of the capillary (3) detected by the displacement detection sensor when the gold ball (16) abuts the IC (11), pressing he gold ball (16) against the electrode forming portion to form a bump pedestal (17), elevating the capillary (3) a specified amount while moving it in the horizontal direction a specified amount, setting the height S of a position at which the capillary (3) is stopped based on the height H1 of the bump pedestal (17) detected by the displacement detection sensor, again lowering the capillary (3) down to the stop position height S to join the gold wire (1) to the bump pedestal (17), and then lifting the gold wire (1) to break the joint between the bump pedestal (17) and the gold wire (1).
摘要:
A method of producing biologically active substances using a hybrid cell line obtained by fusing (1) a human tumor cell line which does not grow in a medium containing aminopterin or/and azaserine or cell line derived therefrom with (2) a human non-tumor macrophage. The human tumor macrophage cell line may be either a thymidine kinase-deficient cell line of U-937 or a thymidine kinase-deficient cell line of THP-1, the non-tumor macrophage may be alveolar macrophage, splenic macrophage, peripheral blood monocyte, peritoneal macrophage, hepatic macrophage, placental macrophage, or thymic macrophage, and the biologically active substance produced is a tumoricidal substance or interleukin-1.
摘要:
An aluminum article is protected against electrochemical corrosive attack by an aqueous medium with which the article is at least partially in contact by the steps of observing the cathodic potential of the article relative to a reference electrode in contact with the medium; when the observed cathodic potential of said article approaches the potential at which pitting corrosion of the same is initiated, electrically connecting said article directly to a source of potential electronegative with respect to the observed potential of the article to repress the cathodic potential of said article to within the alkali corrosion range; and after the cathodic potential is repressed within the alkali corrosion range, disconnecting the article from said electronegative potential source to allow the article to gradually return to its natural cathodic potential in the medium.
