  • Seal member mounting structure in electromagnetic fuel injection valve
    Patent number: 6223727
    Abstract: In an electromagnetic fuel injection valve, a fitting surface of a valve housing, over which a seal positioning ring is fitted, is formed of a diameter smaller than that of an annular sealing surface over which a seal member is fitted. A tapered surface is provided between the fitting surface and the sealing surface, and a resilient projection is formed on the seal positioning ring, so that the projection is in pressure contact with the tapered surface in a state in which the seal positioning ring has been fitted over the fitting surface. Thus, the seal positioning ring can be retained easily and precisely in a regular position on the outer peripheral surface of the valve housing by a reaction force provided by the resilient projection and hence, no post-treatment is required.

  • Supporting structure for heat exchanger
    Patent number: 6223808
    Abstract: An annular-shaped heat exchanger 2 provided with a high-temperature fluid passage inlet 11 at one end in the axial direction and a low-temperature fluid passage inlet 15 at the other end in the axial direction is supported inside a cylindrical outer casing 9 via a heat exchanger supporting ring 36. The heat exchanger supporting ring 36 connecting a low-temperature section near the low temperature fluid passage inlet 15 of the heat exchanger 2 and a rear flange 33 of the outer casing 9 is formed by bending a plate member in a cross-sectionally step shape so that it can readily undergo elastic deformation to offset the thermal expansion of the heat exchanger 2. This ensures positive sealing between the high-temperature fluid passage inlet 11 and the low-temperature fluid passage inlet 15 of the heat exchanger 2 while minimizing the thermal stress occurring in the heat exchanger 2 and the outer casing 9.

  • Color encoder
    Patent number: 6226042
    Abstract: A color encoder is incorporated in an apparatus for reproducing a signal recorded on a disk for a video-CD, CD-G, or similar system. The color encoder serves as an interface between such an apparatus and a television receiver. The color encoder converts R, G, and B signals reproduced from a disk into a color television signal. The color encoder is provided with a circuit for generating a blanking interval control signal that is used to switch between blanking intervals of different duration in accordance with a select signal, so that the duration of the time interval during which video signals are suppressed can be selectively varied. The color encoder has, in the input paths for the R, G, and B signals, switches for enabling and disabling the passage of those signals, and these switches are controlled by the blanking control signal.
