    Abstract: In a scroll compressor, an outer wall curve of a scroll lap of a fixed scroll and an inner wall curve of a scroll lap of an orbiting scroll are formed of involute curves whose basic circle radius is defined as “a”, an inner wall curve of the scroll lap of the fixed scroll and an outer wall curve of the scroll lap of the orbiting scroll are formed of involute curves whose basic circle radius is defined as “b”, and a value of a/b which is a ratio of the basic circle radius a and the basic circle radius b is set to a value exceeding 1.0 and less than 1.5. With this structure, a compression chamber formed on the side of the inner wall of the scroll lap of the orbiting scroll is compressed faster than a compression chamber formed on the side of the outer wall of the scroll lap of the orbiting scroll, and leakage loss during compression process can be reduced.

    Abstract: There is provided a molding method for performing injection molding by using a multi-cavity hot-runner mold having a plurality of valve gates, wherein a proper holding pressure and the like are set for each cavity, a pressure holding step can be carried out, a plurality of products having an appearance free from such a defect as a sink mark can be obtained, the pressure in the cavity can be reduced by a gas pressure, and a necessary mold clamping force can be decreased. A valve for a first cavity is closed after the filling into the first cavity is finished, and a valve for a second cavity is concurrently opened to perform the filling into the second cavity. When injection is effected into each cavity in succession, a gas is injected into the filled resin, thereby to carry out a pressure holding step. The same pressure holding step is carried out for a third cavity and the succeeding cavities. As a result, a plurality of products having an appearance free from such a defect as a sink mark can be obtained. Also, the pressure in the cavity can be reduced by a gas pressure, and a required mold clamping force can be decreased.

The output circuit receives a plurality of pixel signals in a dummy bit portion, an optical black portion and an effective pixel portion from a charge transfer device of the solid-state imaging device.

    Abstract: A scroll compressor includes a back pressure chamber oil-feeding path for feeding lubricating oil from a high-pressure region to a back pressure chamber, and a compression chamber oil-feeding path for feeding lubricating oil from the back pressure chamber to a compression chamber. One phase in which the back pressure chamber oil-feeding path is communicated from the high-pressure region to the back pressure chamber and another phase in which the compression chamber oil-feeding path is communicated from the back pressure chamber to the compression chamber are shifted from each other, so that the back pressure chamber oil-feeding path and the compression chamber oil-feeding path are never put into the communicating state simultaneously. Thus, after a halt of the compressor, under-communication oil-feeding of the lubricating oil from the high-pressure region via the back pressure chamber to the compression chamber can be prevented.

    Abstract: An integrated circuit is provided with a substrate, an electrode, two diffusion areas, and a resistance heater. The substrate includes a first surface and second surface that are substantially parallel to each other. The electrode is laminated onto the first surface. The two diffusion areas are disposed within the substrate in the vicinity of the electrode to form one transistor with the electrode. The resistance heater is located on an area of the second surface across the substrate from the electrode. The resistance heater produces heat by allowing electric current to flow.
