摘要:
A heat rays reflecting film composed of dielectric thin layers (n.sub.H layers) having a relatively high refractive index and dielectric thin layers (n.sub.L layers) having a relatively low refractive index which are alternately piled on one another, is disclosed. The first layer of the heat rays reflecting film, which contacts with the air is n.sub.L layer and the undermost layer which contacts with the window glass is n.sub.H layer. The optical thickness of the first layer is less than .lambda./4 while that of the other layers is .lambda./4. And the thickness of each layer is expressed by the formula: optical thickness/nv wherein nv is the refractive index for visible rays.

A heat-blocking glass comprising: a first layer of infrared rays-blocking film of any thickness formed on a substrate; a plurality of intermediate layers from a second to a (2n+2)th layer (n: positive integral) stacked on said first layer, the optical thickness of each intermediate layer being .lambda./4 (.lambda.: design wavelength); and an uppermost (+3)th layer of a .lambda./8 optical thickness. The refractive index of the first layer is smaller than the refractive index of the second layer. The refractive index of each layer from the second layer to the uppermost layer is arranged so that high-refractive-index layers and low-refractive-index layers are alternately stacked, the second layer being disposed as a high-refractive-index layer.

A pseudomorphic HEMT of a structure which prevents the distribution of 2DEG in the channel layer from being concentrated near the hetero-interface relative to a doping layer and which, at the same time, enables the thickness of the channel layer to which distortion is imparted to be decreased. In an n-InAlAs/InGaAs pseudomorphic structure grown on an InP substrate 1, an InGaAs spacer layer 4 having an In composition ratio smaller than that of an InGaAs channel layer 3 is inserted in an InAlAs/InGaAs hetero-interface. The InGaAs channel layer 3 has an In composition ratio of 0.80 to exhibit a high mobility. Another InAlAs buffer layer 2, spacer layer 5 and doping layer 6 have an In composition ratio of 0.52 which is in lattice-match with the substrate, and InGaAs spacer layer 4 and cap layer 7 have an In composition ratio of 0.53 which is in lattice-match with the substrate. This constitution makes it possible to control the two-dimensional electron gas and to further increase the mobility.
摘要:
A compound semiconductor device including a semiconductor substrate having (100) plane as a crystal growth plane, a first semiconductor layer as an electron traveling layer and a second semiconductor layer for supplying electrons to the electron traveling layer. The first semiconductor layer is formed on the semiconductor substrate and has a different lattice constant from the semiconductor substrate so that a first strain is applied in the first semiconductor layer in a first strain direction. The second semiconductor layer is formed on the first semiconductor layer and has a different lattice constant from the first semiconductor layer to thereby apply a second strain to the second semiconductor layer. The second strain has a direction that is inverse to the first strain direction. In addition, the thickness of the semiconductor layer is defined so as to compensate for the first strain applied to the first semiconductor layer by the second strain applied to the second semiconductor.

An interface transport mechanism employs an upper hand during the transport of a substrate to an exposure device, and employs a lower hand during the transport of the substrate that has been carried out of the exposure device. A fifth central robot employs a lower hand during the transport of a substrate after the exposure processing by an exposure device, and employs an upper hand during the transport of a substrate after the drying processing that has been carried out of a drying processing group. That is, the upper hand is employed to transport a substrate to which no liquid is attached, and the lower hand is employed to transport a substrate to which a liquid is attached after the exposure processing.

In an engine block structure in a multi-cylinder engine in which a piston is incorporated from the side of a crank chamber into each of a plurality of cylinders disposed in series in a cylinder block, cylinder axes of the two adjacent cylinders are disposed to extend in such directions that they are gradually spaced apart from each other as proceeding from the side of a valve operating chamber toward the crank chamber as viewed from a direction of arrangement of the cylinders. Thus, a sufficient crankshaft bearing area can be ensured without bringing an increase in number of parts and an increase in size of the engine block.

A housing of a motor generator is integrally coupled to an end of an internal combustion engine. The internal combustion engine includes an oil pan and a cylinder block which have arcuate stiffener ribs and radial stiffener ribs on end surfaces thereof for increased mechanical strength of the internal combustion engine. The motor generator has a housing that is directly coupled to the internal combustion engine with a relatively small number of parts.

A dispensing carton in which a film wound cylindrically is contained includes a bottom panel, a rear panel, a front panel, both side panels, a lid member which is hingedly joined to the rear panel, a front flange joined to an end of the lid member to overlap the front panel when said lid member is closed, and a cutter mounted along an end of the front flange. The front flange includes a convex edge including, for example, a V-shaped edge. A saw-tooth edge of the cutter mounted along the end of the front flange is arranged into a convex shape such as V-shape. A length from the tip of at least one tooth of the saw-tooth edge nearest to a base of the box to the bottom of a gullet adjacent to the tooth is longer than a length from the tip of other teeth to the bottom of gullets adjacent to the other teeth. When the film is pulled out of the carton and further pulled in the horizontal direction or twisted while being pulled, the tooth of the cutter nearest to the base of the box first cuts into the film. Then, when the film is further pulled, the cut of the film is extended along the arrangement of teeth of the saw-tooth edge so that film is cut easily and completely while keeping the film spread horizontally.
