  • Publication number: 20070079619
    Abstract: Between two heat exchangers of a first heat exchanger unit 41 and a second heat exchanger unit 42 included in an indoor heat exchanger 40, an opening 80 is arranged for introducing indoor air sucked from an air inlet 321 into an indoor blower 50 without being heat-exchanged. At the opening 80, a damper 91 is arranged for adjusting the opening rate of the opening 80, which is driven by a predetermined driving member 92. During a cooling cycle running of a freezing cycle, the opening rate of the opening 80 and/or the devices included in the freezing cycle such as a compressor, blower and expansion valve are controlled alone or in combination so that the temperature of the indoor heat exchanger 40 is lower than a dew point temperature of the indoor air.

    Abstract: A data processing apparatus executes data processing with respect to an output of A/D conversion of an input signal. The data processing apparatus includes a high-frequency noise recognition unit. The high-frequency noise recognition unit detects number of peaks of waveforms of the input signal on a basis of the output of the A/D conversion. The high-frequency noise recognition unit determines whether or not the number of the peaks, which has been detected within a predetermined time, is equal to or larger than a predetermined value.

  • Patent number: 7063135
    Abstract: A heat exchanger includes a plurality of tubes, a pair of header pipes, partition walls, an inlet connector block and an outlet connector block. The plurality of tubes have one ends connected to one header pipe and other ends connected to the other header pipe. The header pipe internally has a pipe-inside flow-through bore. The partition wall is internally formed in each header pipe to divide the pipe-inside flow-through bore into two regions. Each header pipe has a block connector bore opening at an outer side wall opposing to an area to which the tubes are connected and opening to the pipe-inside flow-though bore by cutting out a portion of the partition wall. The inlet connector block is connected to the block connector bore of one header pipe to admit coolant to flow in. The outlet connector block is connected to the block connector bore of the other header pipe to permit coolant to flow out.

  • Publication number: 20050276463
    Abstract: In a visual inspection method and apparatus, a picture processing unit converts an original picture, obtained by taking a photograph of a BGA illuminated by a ring illuminator from above, using a camera, and labels a binary picture obtained by this binary conversion. Then, it forms a rectangle circumscribing an outer circumference of a labeling picture obtained by the labeling, and inverts a labeling picture within the formed circumscribing rectangle, and removes a portion of a region formed by the outer circumference and the circumscribing rectangle in a picture obtained by the inversion, and then generates an inspection picture by adding a picture obtained by the removal to the labeling picture, and accordingly judges a pass or rejection of the inspection target sample based on the generated inspection picture. Thus, the inspection can be carried out at high accuracy irrespectively of a low cost.

  • Patent number: 6961670
    Abstract: A probe testing apparatus reads the surface shape of a contact pad in pressure contact with a contact probe, and differentiates the read surface shape to extract a multiplicity of flat parts. Next, the probe testing apparatus complements the multiplicity of flat parts to generate a reference shape, and subtracts the reference shape from an averaged surface shape to detect a plurality of recesses having a predetermined depth or more. Next, the probe testing apparatus selects one from the plurality of recesses corresponding to reference information, enlarges the selected recess outward by predetermined dimensions, and subtracts the reference shape from the initial surface shape at the position of the enlarged recess to detect an impression of the contact probe. Finally, the probe testing apparatus determines from the position and depth of the detected impression whether the contact probe is acceptable or defective.

  • Patent number: 6803971
    Abstract: Two of four light sources have canceling characteristics with respect to color nonuniformity, and the other two light sources have canceling characteristics with respect to color nonuniformity. A light emission stop detector detects that each of the light sources stops emitting light by blowing its value for example, and feeds, if a certain light source stops emitting light, information indicating that the light source stops emitting light to an energization controller. The energization controller stops, when it receives the information indicating that a certain light source stops emitting light, the energization to a light source paired with the certain light source and puts out the light source.
