    摘要: An apparatus for debonding a wafer from a bonded wafer stack is disclosed. The apparatus includes a flashlamp, a flashlamp control unit, and a wafer debonding unit. A processed wafer can be debonded from a bonded wafer stack by applying light pulses from the flashlamp. The flashlamp is controlled by the flashlamp control unit that includes a capacitor bank, a power supply for charging the capacitor bank, an IGBT-based switching device, and a frequency controller. The wafer debonding unit includes a debonding vacuum table, a wafer feeding robot for conveying the bonded wafer stack to the debonding vacuum table, a set of suction cups for applying vacuum to the bonded wafer stack when light pulses are being emitted by the flashlamp to debond the processed wafer from the bonded wafer stack.

    摘要: An antenna for facilitating remote reading of utility meters is disclosed. The antenna includes a metal rod and a printed circuit board (PCB), both enclosed by an envelope that includes a plastic body and a plastic cap. The plastic body includes a channel for receiving the metal rod. The plastic cap is for covering the plastic body. The PCB includes a dielectric layer located between a first and second metal layers. Secured to the PCB, the metal rod is electrically connected to the second metal layer of the PCB, but not the first metal layer of the PCB.

    摘要: A portable information device capable of supporting a display is described. The portable information device includes a first chassis member and a second chassis member connected mutually rotatable, a first support plate that supports a display on the side of the first chassis member, a second support plate that supports the display on the side of the second chassis member, a first locking member including a first fixing portion to be fixed to the rear face of the first support plate with adhesive, and a first locking piece projecting from one end face of the first support plate, the first locking piece being configured to come in contact with and separate from the rear face of the second support plate. The first support plate includes a first contact face with which the first locking member comes in contact and a first adhesive face that fixes the first locking member with the adhesive. The first adhesive face is recessed from the first contact face by a thickness of the adhesive.
