摘要:
An object of the present invention is to provide a substrate for mounting an IC chip which is a component for optical communication having an IC chip and an optical component integrally provided thereon, which can ensure a short distance between the IC chip and the optical component, which is excellent in electric signal transmission reliability and which can transmit optical signal through an optical path for transmitting optical signal. The substrate for mounting an IC chip of the present invention is a substrate for mounting an IC chip comprising: a substrate and, as serially built up on both faces thereof, a conductor circuit and an interlaminar insulating layer in an alternate fashion and in repetition; a solder resist layer formed as an outermost layer; and an optical element mounted thereto, wherein an optical path for transmitting optical signal, which penetrates the substrate for mounting an IC chip, is disposed.

An electrode assembly including a first cathode member provided with a hole enclosed by a frame portion. The frame portion surrounding the hole has a contact surface that comes into contact with an object to be plated at one of its surfaces, and an insulating member is provided with holes and enclosed by a frame portion, with one surface of the frame portion placed on top of another surface of the frame portion of the first cathode member. A second cathode member also provided with a hole enclosed by a frame portion, with one surface of the frame portion placed on top of one surface of the other frame portion of the insulating member. The smallest bore diameter at the hole of the second cathode member is larger than the smallest bore diameter at the holes and of the insulating member.

An apparatus for the preparation of an elastic absorbent composed of a mixed web. Elements of the apparatus can include two supply hoppers for separately supplying pulverized pulp and staple fibers of a synthetic fiber split yarn at a constant mixing ratio with each hopper having a pair of confronting moving belts, two guide mechanisms located below the hoppers, a pair of nip rollers located below the guide mechanisms, a garnet roll located below the pair of nip rollers, a vacuum device located below the garnet roll, and a mesh belt located between the vacuum device and the garnet roll. Each guide mechanism in the apparatus may include at least two gear guides arranged in series. The apparatus operates by feeding the pulverized pulp and the staple fibers of the split yarn from the hoppers to the nip rolls via the guide mechanisms. The nip rolls compress the material, which is then disintegrated and mixed by the garnet roll. The mixture is pulled onto the mesh belt by the vacuum device.

An X-ray CT apparatus is adapted for switchover between a CT mode to obtain a tomographic image of a subject and a transmission mode to obtain a transmission image of the subject, depending upon projection data acquired in an imager system thereof. The apparatus includes an image-data storage device that stores image data of the subject in a three-dimensional region, a three-dimensional image processor that performs a three-dimensional image processing on the image data and generates three-dimensional image data, for display, corresponding to a line-of-sight direction inputted from an input device, and a transmission-image generator that generates the transmission image as to the image-taking direction, from data acquired in the imager system aligned by the CPU.
摘要:
The present invention uses, as a base material, a multi-layer film comprising more than two layers and formed from thermoplastic resins different in melting point from one another. A sectional construction of the multi-layer film or a tape obtained from the multi-layer film is applied to a sectional construction of a fibre without modification, the multi-layer film or tape being formed into the fibre. The invention provides a composite fibre which is much more excellent as compared to a conventional heat adhesive composite fibre by melt spinning, a water-absorbing material using the composite fibre as a base material and a method for the production of the same by the stated simple means.
