  • Patent number: 11135075
    Abstract: To provide a bioabsorbable stent including: a first tubular unit containing a plurality of cells coupled to each other, each of the cells formed from substantially linear parts and a substantially circular arc part and having a substantially U shape which opens to one end in the axial direction of the stent; and a second tubular unit having the same shape as that of the first tubular unit, the second tubular unit containing a plurality of cells each of which has a substantially U shape which opens to a direction opposite to the opening direction of the opposing first cell. The first tubular unit and the second tubular unit are alternately arranged in sequence to surround a central axis of the stent. Coupling members couple substantially linear parts in some of the opposing cells in the respective neighboring tubular units.

  • Patent number: 9134265
    Abstract: The invention provides a gas sensitive material made from microcrystalline selenium (preferably selenium nanowire) and a gas sensor having an element structure wherein the gas sensitive material is disposed between two electrodes. The invention allows for the kind of organic gas to be distinguished, because microcrystalline selenium reacts with organic gas molecules with high sensitivity at room temperature without being influenced by humidity, and the magnitude of change of the value of the current flowing at a fixed voltage varies depending on the kind of an organic gas to be sensed.

  • Patent number: 6104624
    Abstract: Buck-boost type or buck type chopper circuits and transistors are employed as inverters (IV1, IV2) and power synchronizing switches (SW1, SW2), respectively. A PWM signal is applied to transistors of the chopper circuits to convert DC voltage generated by solar cells (DC1, DC2) into positive and negative half-wave AC voltages for an AC power supply (AC1). The inverters (IV1, IV2) output the AC voltages from their AC output terminals on alternate half cycles thereby to cause backflow of power. The power synchronizing switches (SW1, SW2) performs not only the function of transmitting the half-wave AC voltages generated by the inverters (IV1, IV2) to the AC power supply (AC1) in accordance with the AC cycle of the AC power supply (AC1), but also the function of, when one of the inverters is in operation, insulating the other from the AC power supply (AC1).
