Abstract: A transmissive screen includes a diffusing plate 7 having two first diffusing layers 13 and 15, to which diffusing particles are added respectively, arranged with a second diffusing layer 14, to which diffusing particles whose particle size is smaller than that of the first diffusing layers 13 and 15 are added, in between. Accordingly, even in the case where a diameter of a projection pupil of a projection lens that projects light onto the transmissive screen is small, an image glaring when displaying a bright image can be controlled, while minimizing deterioration of gain, resolution and uniformity.

Abstract: In a transmission type screen structured to have at least two layers, namely, a first layer having a lenticular lens and having black stripes on the viewer's side relative to the lenticular lens and a second layer adjacent to the first layer, which are disposed sequentially as viewed from the viewer's side, the focal distance of the lenticular lens of the first layer is so set that external light having been skewly incident from the viewer's side and having passed through the gaps between the black stripes of the first layer is reflected on the lens surface of the lenticular lens of the first layer to impinge on the black stripes, whereby the “waviness” due to the light reflected by the second layer can be suppressed more effectively.

Abstract: The present invention finds utility in the field of therapy of paraaortic lymph node tumors, and is directed to provisions of a drug perfusion method capable of preventing a drug delivered to the site of tumor tissue from leaking into the surrounding tissue regions, effectively exposing the lymph nodes to a drug of high concentration, and reducing or preventing adverse side effects which would otherwise be imposed on the patient; to a catheter-introducing sheath; and to an axygenated blood perfusion apparatus. According to the invention, balloon catheters 32-1, 32-2, 32-3, 32-4, 32-5, 33, and 34 are employed to block the right renal artery 20, the left renal artery 21, the celiac artery 12, the superior mesenteric artery 19, the inferior mesenteric artery 24, the aorta 3, and the inferior vena cava 4, respectively, whereby a blood-vessel-blocked region is created.

Abstract: A projection panel assembly is mounted on a casing for holding a screen so as to mount a front panel on the viewing side of the screen. The projection panel assembly includes a fixing portion for directly fixing the front panel and a supporting portion for movably supporting the front panel via the fixing portion. This makes it possible to absorb any distortion of the front panel due to thermal expansion and contraction.

Abstract: An intra pelvic cancer therapeutic agent perfusion apparatus and method for administering a cancer therapeutic agent to and recovering same from a cancer tissue site within the pelvis. The tip of a first sheath is percutaneously inserted into the femoral artery and the tip of a second sheath is inserted into the femoral vein. A first balloon catheter is inserted into the aorta through the femoral artery and a second balloon catheter is inserted into the vena cava through the femoral vein. The first balloon catheter is used to block the blood flow and the second balloon is inflated to form an intravenous closed region between the site of insertion in the vena cava and a lower limb side venous site. A body fluid containing a cancer therapeutic agent is administered to the intra arterial closed region through the first sheath and is removed therefrom through the second sheath.

Abstract: A small-sized multilayer inductor having a greatly increased inductance value includes two thin-film coils with an insulation layer interposed therebetween, the coils being disposed on a coil-winding portion of a wound-core member. At positions opposing flanges of the wound-core member, two terminal electrodes for a first thin-film coil are respectively provided. To one of the two terminal electrodes, the starting end of the first thin-film coil is electrically connected via one connection opening while the finishing end of the first thin-film coil is electrically connected to the other terminal electrode via the other connection opening. Similarly, at positions opposing the flanges of the wound-core member, two terminal electrodes, which are electrically connected to a second thin-film coil, are respectively provided.

Abstract: A projection panel assembly is mounted on a casing for holding a screen so as to mount a front panel on the viewing side of the screen. The projection panel assembly includes a fixing portion for directly fixing the front panel, and a supporting portion for movably supporting the front panel via the fixing portion. This makes it possible to absorb the distortion of the front panel or the like due to expansion and contraction.

Abstract: A train control system includes an equipment for issuing, to a train under control based on a predetermined train schedule, an operational target to be attained in terms of the aimed position, aimed time and aimed speed. Once a target is issued, a possible run region of the train is determined, and another target may be set within the possible run region such that the train is not subjected to the ATC-based speed limitation or the like, thereby minimizing the cause of delay of the train operation.

Abstract: A premixing-type spray gun which mixes a paint and compressed air inside the atomizing head thereof and sprays out the mixture as atomized from the spray hole, having a flow control valve to adjust the sectional area of the paint supply path communicating with the paint nozzle or having a relief valve disposed downstream of a throttle path made of the inlet path through which the spraying air pressure is partially supplied into the pressurizing container.The flow rate of the paint can be adjusted independently of the trigger operation of the spray gun, and the amount of the paint suppled under pressure can be controlled, thereby keeping a stable spray amount.

Abstract: A low pressure atomizing spray gun is disclosed in which paint is injected from a nozzle, an opening of the nozzle is controlled by a needle valve, air is mixed with a flow of paint, air is blown from both sides after the air-paint mixture is sprayed from a spraying nozzle and it is again mixed and atomized. The nozzle is formed as circular hole with a circular outer shape, and the spray hole is designed with a lip-like shape having different dimensions in longitudinal and lateral directions and with a conical or similar shape. Lateral air holes are furnished in front of the spray hole, at opposite positions on both sides of the spray flow and function to blow the diffusing air flow toward the spray flow. A pair of longitudinal air holes is furnished to inject the secondary air obliquely from behind the spray hole and to make the air collide with the flattened spray pattern.

Abstract: A gas-permeable material with excellent compatibility with blood comprising polyurethane, polyurethaneurea, or the derivatives thereof is provided. The polyurethane or polyurethaneurea is obtained from a composition that comprises diisocyanate; polysiloxane containing terminal hydroxyl groups; and polyol or polyamine containing at least one tertiary amino gorup. The derivatives of the polyurethane or polyurethaneurea is obtained by the following steps of: converting the tertiary amino groups contained in the polyurethane or the polyurethaneurea to quarternary ammonium groups, and treating the polyurethane or the polyurethaneurea having quarternary ammonium groups with heparin.
