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.

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.

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.

A gas-fired engine that supplies high-pressure liquefied gas (e.g., LNG) as fuel by a reciprocating pump. A gas fuel supply device includes: a reciprocating pump driven by a hydraulic motor to boost an introduced liquefied gas pressure to a desired pressure and discharge the liquefied gas; a hydraulic oil introduction line that introduces a portion of high-pressure hydraulic oil from a hydraulic oil line and supplies the high-pressure hydraulic oil to the hydraulic motor; a hydraulic oil return line that returns the high-pressure hydraulic oil to the hydraulic oil line; a heating unit that heats and gasifies the boosted liquefied gas; a control section that adjusts a rotational speed of the hydraulic motor to maintain constant a gas fuel outlet pressure of the heating unit; and an engine inlet gas pressure-reducing valve that regulates a gas fuel pressure injected into a combustion chamber.

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.

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.

Provided is an engine-exhaust-gas energy recovery apparatus including a hybrid turbocharger having a turbine unit that is supplied with exhaust gas discharged from an engine, a compressor unit that pressure-feeds scavenging-air pressure to the engine, and a generator/motor unit that generates electricity when the turbine unit is driven; a bypass channel that allows the exhaust gas supplied toward the hybrid turbocharger to bypass the hybrid turbocharger; an engine-load detecting part; an engine-rotation-speed detecting part; a scavenging-air-pressure detecting part; and a control device having a database for calculating a scavenging-air pressure, at which the fuel consumption rate of the engine becomes lower than or equal to a predetermined value, from the detection values of the respective detecting parts. The control device controls an exhaust-gas bypass control valve so as to control the scavenging-air pressure of the engine.

Providing an exhaust gas energy recovery device by which the optimal engine operating condition can be continuously maintained in a manner that the flow rate of the engine exhaust gas fed to the power turbine is regulated so that the scavenging air pressure becomes optimal in order that the engine performance (the fuel consumption rate) corresponding to the engine load and the engine speed becomes optima. The engine exhaust gas energy recovery device provided the engine load detecting sensor, the engine speed detecting sensor and the scavenging air pressure detecting sensor, the device regulating the flow rate of the exhaust gas streaming into the exhaust gas turbocharger via controlling the flow rate of the exhaust gas streaming into the power turbine of the exhaust gas energy recovery device, so that the scavenging air pressure is maintained at an arbitrarily ordered level and the engine is operated under a condition that the fuel consumption rate is minimal.
