Title: Electric wave absorber
Inventor: SUZUKI SHUNSUKE
IPC: H01Q17/00
Filed: 1988-11-14
Abstract: PURPOSE:To achieve improved electric wave absorbing properties with less weight by providing a porous Al sintered board consisting of a cladding layer of paint whose surface contains an electric wave absorbing material or an electrical conductor board directly or through an air layer at the rear surface of this sintered board. CONSTITUTION:One type or more electric wave absorbing body powder 11 selected from a magnetic material or a dielectric material is fitted to a porous Al sintered board 10 in this electric wave absorbing body. The porous Al board 10 allows an incident electromagnetic wave R to repeat irregular reflection within this sintered board and electromagnetic wave capturing effect to the electric wave absorber powder 11 to be increased. At the same time, it converts one part of electromagnetic wave scattered inside into electrical energy to allow the incident electromagnetic wave R to be absorbed. Also, an electromagnetic wave Rn which passes the porous Al sintered board 10 and whose high energy is attenuated is absorbed as an electrical energy by a metal conductor board 15 and intrudes into the porous Al sintered board 10 again. Thus, energy is absorbed completely.

Filed: 1999-10-12
Abstract: PROBLEM TO BE SOLVED: To provide an input interface circuit capable of sufficiently securing a noise margin even when the voltage value of power supply voltage is low. SOLUTION: A power supply voltage detection circuit 10 detects whether power supply voltage VDD is more than a prescribed value or not and indicates the detected result as an output signal S10.
