  • Publication number: 20120306299
    Abstract: In a semiconductor module, a high-potential side conductor includes a wide section on which the high-potential side switching element is mounted, a high-potential side terminal coupled with a high potential source, and a narrow section extending from the wide section to the high-potential side terminal in a first direction. The wide section is wider than the narrow section in a second direction perpendicular to the first direction. The wide section has a first side and a second side opposite to the first side in the second direction. A distance between the first side of the wide section and a low-potential side conductor is shorter than a distance between the second side of the wide section and the low-potential side conductor. The narrow section extends from a portion of the wide section closer to the first side than the second side.

  • Patent number: 6704575
    Abstract: A cordless telephone set includes a base unit and a terminal unit. The base unit, which has detected by a terminal-unit detecting circuit that the terminal unit is placed thereon, awaits an identification number of the terminal unit to be transmitted from the terminal unit. The base unit receives the identification number of the terminal unit via an antenna and a transmitting-receiving unit. A control unit determines whether the identification number of the terminal unit is on a terminal unit identification number list of terminal units having a relationship with the base unit, which is recorded in memory. If the determination result is negative, the identification number is added to the list, thus updating the terminal unit identification number list. Next, the base unit transmits its identification number to the terminal unit. Likewise, the terminal unit updates a base unit identification number list.

  • Patent number: RE37926
    Abstract: A semiconductor light-emitting device which emits first light of a wavelength absorbed by a substance containing an OH group is sent toward a detection object. A semiconductor light-emitting device emits second visible light toward the detection object. A photoreceptor receives light from the detection object and acquires first and second received light-quantities derived from the respective ones of the first and second light. A processing system corrects the first photoreceiving quantity on the basis of the second photoreceiving quantity. The processing system determines the color of the detection object by the second photoreceiving quantity, and corrects the first photoreceiving quantity on the basis of this determination result. Further, it compares the corrected first photoreceiving quantity with a prescribed threshold value, detects whether or not water, which is the subject containing the OH group, is contained in the detection object, and outputs the same as an output signal.
