  • Patent number: 10386227
    Abstract: A photosensor of the present invention includes a circuit portion (34), a collective cable support portion (42), a pressure-welding portion (36a˜36d) and a cable end support portion (46a˜46d). The circuit portion (34) is configured to control the light projecting element and the light receiving element. The collective cable support portion (42) is configured to support a collective cable (10) including a plurality of cables (12a˜12d). The pressure-welding portion (36a˜36d) is configured to perform conduction with the circuit portion (34) by pressure-welding and fixing each of the plurality of cables (12a˜12d). The cable end support portion (46a˜46d) is configured to support an end of each of the plurality of cables (12a˜12d). In each of the plurality of cables (12a˜12d), a length from the pressure-welding portion (36a˜36d) to the cable end support portion (46a˜46d) is longer than that from the collective cable support portion (42) to the pressure-welding portion (36a˜36d).

  • Patent number: 6241011
    Abstract: A layered heat exchanger for use as a motor vehicle air conditioner evaporator comprises pairs of generally rectangular adjacent plates, which are joined together in layers with the corresponding recesses of the plates in each pair opposed to each other to thereby form juxtaposed flat tubes each having a U-shaped fluid channel, and front and rear headers in communication respectively with opposite ends of each flat tube. The turn portion of U-shaped fluid channel of the flat tube has a fluid mixing portion comprising many small projections, and a rectifying portion comprising parallel long projections along a flow of fluid. The channel turn portion rectifies the flow of fluid and mixes the fluid at the same time, permitting the fluid to flow through the turn portion smoothly to result in a diminished fluid pressure loss, an improved heat transfer coefficient and improved performance.
