摘要:
A pressure-sensitive adhesive sheet has a high adhesiveness and an excellent terminal peeling resistance as well as exhibits extremely small diffusing amounts of formaldehyde and toluene. The pressure-sensitive adhesive sheet contains at least a pressure-sensitive adhesive layer of a water-dispersion type acrylic pressure-sensitive adhesive containing a water-dispersion type acrylic polymer and a tackifying resin-containing emulsion, wherein a diffusing amount of formaldehyde is less than 3 μg/m3 and a diffusing amount of toluene is 10 μg/g or less. As the tackifying resin-containing emulsion, a tackifying resin-containing emulsion prepared using substantially no organic solvents or a tackifying resin-containing emulsion prepared using a material other than aromatic hydrocarbon-based organic solvents can be suitably employed.

The present invention provides a bump-joining apparatus, a bump-joining method, and a semiconductor component-manufacturing apparatus whereby bumps and electrode portions of circuit board are perfectly joined with higher join strength than in the conventional art. The apparatus includes a vibration generation device, a pressing device and a control unit, wherein bumps are pressed to electrode portions of a circuit board and vibrated with ultrasonic waves after reaching an initial contact area before reaching a join-completed-contact area at a completion of the joining, so that the bumps are more perfectly joined to the electrode portion than in the conventional art which vibrates the bump only after reaching the join-completed-contact area. Larger join strength is achieved than in the conventional art.

A document feeder to be mounted atop an image reading device having a stationary optical system disposed under a contact glass. The document feeder includes a document original plate for holding thereon document originals, a document original feeding mechanism for feeding a document original from the document original plate onto a contact glass, a document original transporting mechanism for transporting the document original fed by the document original feeding mechanism along the upper surface of the contact glass, a document original discharging mechanism for discharging the document original transported by the document original transporting mechanism, and a document original discharge plate for receiving the document original discharged by the document original discharging mechanism. The document original feeding mechanism, the document original transporting mechanism and the document original discharging mechanism are integrally supported in a unit body to constitute a single unit.
摘要:
A sheet feeding apparatus having a feeding roller for feeding a sheet, a support shaft forwardly and reversely rotatable integrally with the feeding roller and a stopper disposed upstream of the feeding roller in the sheet feeding direction for temporarily regulating the feed of a sheet to the feeding roller. When the rotation in one direction of the feeding roller is transmitted to a locking member through a one-way clutch, the locking member is rotated to lock the stopper. When the feeding roller is rotated in the opposite direction, the locked state of the stopper is released.
摘要:
In an information processing apparatus having a central processing unit, input/output units controlled by the central processing unit such as a liquid crystal display, a hard disk drive, a PCMCIA controller and a floppy disk drive, and a battery for supplying power to the central processing unit and the input/output units, a desired operating time of the information processing apparatus is set in a desired operating time setting circuit. Next, a residual capacity detecting circuit detects a residual capacity of the battery. On the basis of the desired operating time set by the desired operating time setting circuit and an operable time of the information processing apparatus calculated from the residual capacity of the battery detected by the residual capacity detecting circuit, the central processing unit commands an operating condition changing circuit to change operating conditions such that the desired operating time becomes longer than the operable time. The operating condition changing circuit controls power consumption in the input/output units such that the changed operating conditions are met, thus ensuring the desired operable time of the information processing apparatus to be realized.
摘要:
An image-forming machine comprises a sheet member conveying passage extending through a transfer zone and a fixing zone, a sheet member-feeding means for feeding a sheet member onto the sheet member conveying passage, and a sheet member conveying means for conveying the sheet member through the sheet member conveying passage. A housing of the image-forming machine has a lower surface defined by an intermediate lower wall and an upper surface defined by an intermediate upper wall, and forms a space of which the front surface is opened. The downstream end portion of the sheet member conveying passage extends along a one side portion of the intermediate lower wall on the lower side thereof. The one side portion of the intermediate lower wall is defined by the opening/closing member, and opening/closing member is brought to the open position to open the downstream end portion of the sheet member conveying passage. The sheet member conveying means includes a pair of register rollers. After the leading edge of the sheet member delivered onto the sheet member conveying passage is brought into contact with the nip of the pair of register rollers, the pair of register rollers are preliminarily rotated for only a predetermined period of time.
摘要:
Bile acids in the feces can be easily examined on a mass scale. Further, colon cancer at an early stage can be detected and the latent colon cancer can be diagnosed. The concentration of primary bile acid (CA) in the feces is measured by an ELISA method with the use of an anti-bile acid antibody for primary bile acid which comprises anti-cholic acid-24-bovine serum-rabbit serum, the concentration of secondary bile acid (DCA) in the feces is measured by an ELISA method with the use of an anti-bile acid antibody for secondary bile acid which comprises anti-deoxycholic acid-24-bovine serum-rabbit serum, and the concentration ratio (DCA/CA) of the secondary bile acid to the primary bile acid is calculated from the measured values.
