摘要:
A fin (3) of a fin-tube heat exchanger (1) has protuberances (5) each disposed between two adjacent heat transfer tubes (2, 2) and holes 8 (cut-outs) each formed upstream of the protuberances (5). Each of the protuberances (5) has, as an upstream portion adjacent to the hole (8), a wing portion (6) tapering toward an upstream side.

A nonaqueous inkjet ink composition that at printing by an inkjet printer, is free from clogging of a nozzle of printer head part and that excels in ink delivery stability leading to prints of excellent printing quality. The nonaqueous inkjet ink composition is one containing a pigment, a resin, a pigment dispersant, an organic solvent and an aminated alcohol, characterized in that the content of the aminated alcohol is in the range of 0.01 to 3 mass % based on the whole mass. The nonaqueous inkjet ink composition may be one characterized in that the water extract from the nonaqueous inkjet ink composition exhibits a pH value ranging from 6.0 to 10.0.

The present invention provides a new method for distributing video information to a mobile phone based on push technology where a new function of a mobile phone is utilized sufficiently. In case that a user has registered that the user makes a request for a video information distribution service about a specific area to a user management sever in advance, when a mobile phone of the user exists in the specific area, video information is distributed from a video contents server to the mobile phone of the user based on push technology. Alternatively, when traffic of a radio channel connected to the mobile phone carried by the user is lower than a predetermined threshold, video information is distributed from a video contents server to the mobile phone based on push technology.
摘要:
A liquid container is provided with an atmospheric air communicating port communicated with atmospheric air in an upper portion thereof, and a liquid supply port for supplying ink contained in the liquid container to a recording head in a lower portion thereof. A negative pressure producing member for retaining ink and imparting a negative pressure to the recording head is contained in the liquid container. On an upper wall in the liquid container on which the atmospheric air communicating port is provided, a plurality of ribs are integrally formed to protrude to the inside of the liquid container. A space portion is formed between the upper wall of the liquid container on which the ribs are disposed and an upper surface of the negative pressure producing member. A capillary channel for generating a capillary force is provided on the upper wall and side walls of the liquid container which form the space portion.

In an electrical connector to be attached to a circuit board, a terminal has a contact section on one free end side to contact with a terminal of a mating connector and has a connecting section on the other free end side to be connected by soldering to a circuit portion of a circuit board. The terminal has a holding section and a connecting section. The holding section has a face-contact section, a backside section, and a side-face section. The terminal has a low solder wetting area at least on a part of a circumferential area of the holding section in the longitudinal direction, and the contact section is formed above the upper end of the low solder wetting area on the backside section. The upper end of the low solder wetting area is provided below the upper end at the side-face sections and the contact-face section.

There are provided are an adhesive composition that keeps storage stability and further gives a cured product wherein metallic bonds are formed in the state that the cured product wets its components and is satisfactorily spread between the components (or parts), thereby turning excellent in adhesive property, electroconductivity, and reliability for mounting such as TCT resistance or high-temperature standing resistance; an electronic-component-mounted substrate using the same; and a semiconductor device. The adhesive composition comprises electroconductive particles (A) and a binder component (B), wherein the electroconductive particles (A) include a metal (a1) having a melting point equal to or higher than the reflow temperature and containing no lead, and a metal (a2) having a melting point lower than the reflow temperature and containing no lead, and the binder component (B) includes a thermosetting resin composition (b1) and an aliphatic dihydroxycarboxylic acid (b2).
摘要:
A fixed electrode and a movable electrode to be used to drive each arm are formed at a drive unit. As a voltage is applied between the fixed electrode and the movable electrode, the movable electrode is caused to move by coulomb force, thereby driving the arm 3 in a closing operation. By detecting a change occurring in the electrostatic capacity between the fixed electrode and the movable electrode at this time, a decision can be made as to whether or not the sample has been gripped.
