A heat exchanger includes a plurality of tubes 2 through an inner cavity of which a heat-transfer medium liquid flows, a sealing member 6 that seals the plurality of tubes 2 while exposing both ends thereof, with a blood channel passing outside each of the tubes 2 being formed in a central portion in the axial direction of the tubes, and a housing 5 that accommodates the tubes 2 sealed with the sealing member 6. The heat exchanger further includes a hollow fiber membrane 3 that is formed of a plurality of hydrophobic and gas permeable hollow fibers 4 and that is disposed on at least one of an entrance side and an exit side of the blood channel in the housing 5 so that a liquid flowing through the blood channel passes through the hollow fiber membrane 3. The housing 5 includes openings 10 for exposing open ends of each of the hollow fibers 4 forming the hollow fiber membrane 3 to the outside, and gaps between an inner side of the openings and the hollow fibers 4 are sealed. Air can be removed while suppressing a reduction in the heat exchange efficiency.

The disclosed subject matter includes a surface mount electronic device with high reliability and favorable optical characteristics. The surface mount electronic device can include a circuit board with at least one conductor pattern formed on an insulating board and an electronic component that is mounted on a die bonding pad located on the at least one conductor pattern with an adhesive material. The die bonding pad can include a plurality of cutout sections that expose the insulating board and extend towards a center from a circumference thereof. Therefore, the adhesive material can adhere to both the die bonding pad and the insulating board exposed in the plurality of cutout sections along with the electronic component. In this case, the plurality of cutout sections can be formed so as not to drag the adhesive material upwards on each of the side surfaces of the electronic component. Thus, the surface mount electronic device can improve reliability thereof while maintaining predetermined optical characteristics.

The system of the present invention is configured to online support the operation of a device using an expendable under restriction of refill. The system receives device information regarding identification of a model of the device and expendable information including a degree of consumption of the expendable from the device via a network, and estimates an operating status of the device under restriction of the refill of the expendable according to the received device information and the received expendable information. The system generates device support information relating to the operation of the device under restriction of the refill of the expendable based on the estimated operating status of the device, and outputs the generated device support information via the network. The arrangement of this system desirably relieves both the user load and the support load in maintenance and support of the device.
摘要:
An LED device manufacturing method can produce an LED device that can emit light of a given color tone by additive color mixture of light emitted from an LED chip and light obtained by wavelength conversion of the light emitted from the LED chip. The wavelength conversion can be accomplished by using a wavelength conversion material, such as a fluorescent material. The LED device can have good efficiency of extracting light from the LED and can have high luminous intensity. First cups and second cups can be formed in a substrate including a pair of conductor patterns formed on an insulating portion. The first and second cups can have co-planar bottom surfaces. LED chips can be mounted on die bonding pads that are provided on the bottoms of the first cups. The die bonding pads can be connected to one of the conductor patterns. An upper electrode of each LED chip can be connected to a wire bonding pad extending from the other conductor pattern via a bonding wire. A fluorescent resin containing a transparent resin with a fluorescent material added thereto can be injected into the second cup and then dispersed to fill the first and second cups with the fluorescent resin due to the resin's natural flow. A lens made of a transparent resin can be formed above each LED chip.
