  • Patent number: 10292251
    Abstract: An X-ray inspection device achieves a high cooling effect without using an expensive air conditioner and is excellent in cleaning property. The inside of a first case of an X-ray inspection device is separated into plural cooling partitions by separation walls by the use limit temperature and the like, and heat sources respectively having intrinsic use limit temperature are stored in respective partitions. Because a flow passage of air is set inside the cooling partition so that the heat sources having low use limit temperature are disposed upstream of the heat sources having high use limit temperature, the cooling efficiency is excellent. A heat absorption member of a heat exchange device exists inside the first case, and a heat radiation member exists inside a second case communicating with the external air. Because there is no protrusion of the heat radiation member as the total cases, cleaning property is excellent.

  • Patent number: 8064211
    Abstract: An electronic component module is configured by a passive component mounted on a built-in IC substrate. The passive component is provided with a passive element inductor, and a mounting surface for mounting on a substrate. Concavities are respectively provided at parts of two opposed borders in the mounting surface, and a terminal electrode is provided at the bottom part of the concavities. Since the passive component has a concavity within the mounting surface and the terminal electrode is incorporated within this concavity, the passive component can be mounted low on the substrate surface. Since the terminal electrode is incorporated in the concavity, solder is prevented from spreading fillet-like at the periphery of the inductor, thus increasing the mounting density of the passive component. There is increased freedom for mounting the passive component because the passive component is mounted on the built-in IC substrate in which the IC is embedded in the substrate.

  • Patent number: 7894303
    Abstract: An object is detected without being constrained by the positional relationship between the object and the detecting position. A detection device includes a pseudo sound source and a monitoring unit. The pseudo sound source generates a scanning sound wave of a phase-conjugate wave in the time domain based on an acoustic signal by performing active phase conjugation, and causes the scanning sound wave to converge on the detection object from the above thereof within the propagation space by utilizing a feature that the scanning sound wave converges on the pseudo sound source which is the generation source of the acoustic signal. The monitoring unit extracts a reflected sound wave which is reflected at the detection object from the sound wave in the propagation space by performing passive phase conjugation. The detection object is detected based on presence or absence of the extracted reflected wave.

  • Patent number: 7225810
    Abstract: An on-off valve mounted in a high pressurized gas container, which has a holding portion for holding a flow amount controlling member in a path formed in an upper stream side of the body of the valve, and in which a flow amount controlling member is movably held. In the flow amount controlling member, an orifice is formed. When the valve moves into an opening position, a high pressurized oxygen gas is flowed into a valve chamber by gas pressure, the flow amount controlling member moves and closes the path. At this time, the gas flow amount is restricted by the orifice, so that the pressurizing speed of the gas pressure at the down stream side of the orifice becomes slow and then heat generation due to the adiabatic compression is reduced.

  • Patent number: 7212095
    Abstract: Conductor layers 2A and insulating layers 4A are alternately stacked so as to prepare a base material 17. A plurality of grooves 18 having a predetermined width are formed in a surface of the base material 17 in such a manner that these plural grooves 18 are located parallel to each other along a stacking layer direction in order to form a coil inner peripheral portion. Embedding materials 5 are filled into the grooves 18. Surfaces 16 of the base material into which the embedding materials 5 have been filled are flattened by polishing. The conductor layers 2A located adjacent to each other are connected to each other, so that helical coils which constitute inductive elements are constructed. Then, both the front plane and the rear plane of the resultant base material are covered by an insulating layer, which is cut so as to obtain respective chips.
