    Abstract: A projector device adapted to project an image-forming beam using a lamp as a light source. The lamp is installed within a rectangular parallelepipedal housing, and an exhaust fan is disposed to the rear of the lamp. The top wall of the housing surrounding the lamp is given an opening pattern asymmetric about the optical axis of the lamp by forming an air inlet opening in a position deviated from the optical axis is toward a direction orthogonal to the axis for producing a swirling air current within the housing by operating the exhaust fan. The lamp can be effectively cooled with reduced quantities of air.

  • Patent number: 6913852
    Abstract: A battery module has a plurality of electrically connected unit cells fixed in a container. A buffer member is provided at the void between the inner wall of the container and the unit cell. By virtue of the buffer member in the battery module formed of a heat conductive elastic body, the requirement of vibration resistance can be met by the buffer member while the heat generated by the unit cell can be easily discharged via the buffer member. Thus, a battery module suppressed in degradation of the performance of the unit cell caused by heat can be provided.

  • Patent number: 6914182
    Abstract: Two types of solar cell modules having an equal output voltage and different sizes are used, and a plurality of solar cell modules of these two types are installed so that they are connected in parallel. The size of a solar cell module having two solar cell sub-modules is two times larger than the size of a solar cell module including one solar cell sub-module. By connecting two power generating regions of each of the solar cell sub-modules of the former solar cell module in parallel, connecting adjacent two solar cell sub-modules in series and connecting two power generating regions of the solar cell sub-module of the latter solar cell module in series, an equal output voltage is obtained from both of the solar cell modules.

  • Patent number: 6914465
    Abstract: A PLL circuit that optimally generates a clock signal with two reference signals having different frequencies. The PLL circuit includes a VCO for generating the clock signal in accordance with a control voltage. A first loop controls the frequency of the clock signal in accordance with a first reference signal. A second loop controls the phase of the clock signal in accordance with a second reference signal, whose cycle is longer than that of the first reference signal. The second loop supplies the VCO with the control voltage at a constant value until the difference between the frequencies of the first reference and clock signals converges to within a predetermined range. Then, the second loop supplies the VCO with a control voltage at a level corresponding to the difference between the phases of the second reference and clock signals.

  • Patent number: 6914280
    Abstract: Since a 5 GHz-band broadband has a frequency twice that of 2.4 GHz, the parasitic capacitance greatly influences deterioration in isolation of a switching device used in this frequency region. Therefore, to improve isolation, a shunt FET is added to the device. The switching device also includes a protecting element that has a first n+-type region, an insulating region and a second n+-type region. This protecting element is connected in parallel between two electrodes of the shunt FET. Since electrostatic charges are discharged between the first and second n+-type regions, the electrostatic energy reaching an operation region of the shunt FET can be reduced without an increase in parasitic capacitance.

  • Publication number: 20050139947
    Abstract: A Schottky barrier diode in which a p+-type semiconductor layer is provided in an n?-type epitaxial layer can realize lowering the forward voltage VF without considering leak current IR. However, when compared with a normal Schottky barrier diode, the forward voltage VF is generally high. When a Schottky metal layer is suitably selected, although the forward voltage VF can be reduced, there is a limit in further reduction. On the other hand, when the resistivity of the n?-type semiconductor layer is reduced, although the forward voltage VF can be realized, there is a problem that breakdown voltage is deteriorated. In a semiconductor device of the invention, a second n?-type semiconductor layer having a low resistivity is laminated on a first n?-type semiconductor layer capable of securing a specified breakdown voltage. P+-type semiconductor regions are made to have depths equal to or slightly deeper than the second n?-type semiconductor layer.

  • Publication number: 20050136603
    Abstract: This invention offers a manufacturing method which does not cause a reduction in thickness of a silicon substrate or a carbon contamination in forming a transistor having an LDD stricture and silicide layers formed by a salicide technology. After a gate electrode is formed on the silicon substrate through a gate insulation film, an insulation film made of the same material as the gate insulation film is formed on the gate electrode. A first insulation film made of a material different from the material of the gate insulation film and the insulation film on the gate electrode and a second insulation film made of the same material as the material of the gate insulation film and the insulation film on the gate electrode are formed over the silicon substrate. Spacers made of the second insulation film are formed by dry-etching. Then the LDD structure and openings for forming the silicide layers are formed using wet-etching.
