Abstract: A photocurable resin laminate comprising a support and a photocurable resin layer disposed on one surface of said support, said photocurable resin layer having:         (a)  a viscosity of from 104 to 5 x 105 poises as measured at 90 °C;         (b)  a thickness of from 30 to 150 µm; and (c)  an ultraviolet ray transmittance of from 40 to 95 % with respect to ultraviolet rays having a wavelength of 365 nm.    When this photocurable resin laminate is laminated under pressure on both surfaces of a metal-clad insult-ing base board having through-holes of an inner diame-ter smaller than 0.5 mm so that both surfaces of the metal-clad insulating base board are covered with the photocurable layer of the photocurable resin laminate, the photocurable resin layer intrudes locally in the inner side of the inner circumferential edge of both terminal openings of each through-hole and extends from the inner circumferential edge along and on the inner wall of the through-hole to a predetermined depth.  By the light exposure of such a laminate structure and the subsequent development, both terminal openings of each through-hole can be completely covered with a photo-cured resin layer without occurrence of coverage fail-ure, wherein a photocured resin layer adhering to the inner wall of the through-hole is formed in the through-hole from the inner circumferential edge of the terminal opening thereof along and on the inner wall of the through-hole.  Accordingly, when the subsequent etching with an etching solution is performed to remov-ing unnecessary conductive layers in areas other than the desired circuit portions, a printed circuit board having small-diameter through-holes can be obtained in which the electric conduction between both surfaces of the board which is established through the through-holes has high reliability.

Granted: 1995-07-18
Abstract: A  dual  lumen  catheter  apparatus  and  method.    The apparatus has an elongated catheter body adapted for insertion into a vein or a fluid-containing body cavity of a patient such as the right atrium of a heart.  The catheter body has a septum that runs longitudinally through the interior of the catheter body so as to divide the interior of the catheter into a first and a second lumen.  The septum is offset from the longitudinal center axis of the catheter so that the cross-sectional area of the two lumens are of different sizes.    The first lumen has a cross-sectional size that is relatively large so that a sufficient volumetric flow rate of blood that is to be oxygenated is able to flow by means of gravity drainage through the first lumen whereas the second lumen is smaller but is still sufficiently large so that an essentially equal volumetric flow rate of blood that has been oxygenated can be returned under pressure through the second lumen.

Title: Receiving antenna apparatus for broadcast by satellite
Inventor: UEMATSU MASAHIRO
IPC: G01S3/48
Filed: 1992-12-09
Granted: 1996-06-04
Abstract: A receiving antenna apparatus for broadcast by satellite for mount on a mobile body in which radio wave interruption tends to occur by obstacles attains high-speed automatic tracking function capable of catching the satellite again in a short time just after cutting off of radio waves.  In the receiving antenna apparatus, an incoming direction of radio waves is roughly detected to limit a search area and then a gain of tuners is then reduced to a value in the tracking control capable of detecting a peak and confirming a main lobe in accordance with power level of the received signal, 80 that a narrow and fine search may be made only in the limited search area.  The antenna apparatus includes a gain setting device for varying gains of AGC of tuners.  Upon search of the satellite, gains of the tuners are set to a first gain by the gain setting device to perform the rough search and the gains of the tuners are reduced to a second gain lower than the first gain to perform the fine search.  Thus, a time required to catch the satellite again after cutting off of radio waves can be made reduced.
