Title: In-tube magnetic flaw detecting
Inventor: ANDO SEIGO
IPC: G01N27/83
Filed: 1987-05-07
Abstract: PURPOSE:To improve flaw detection accuracy by compensating variance in detection sensitivity for pitting corrosion automatically. CONSTITUTION:Magnetic sensors 3 (3a-3n) detects leak magnetic flux at a tube to be inspected which is not shown in a figure and a multiplexer 11 extracts output electric signals S3a-S3n from the respective sensors 3a-3n on a time-division basis. An extracted signal Si is inputted to a microcomputer 13 through a signal amplifier 12 to analyze the frequency of the signal Si. Then an LPF 14 removes a magnetic sensor output signal from a pitting corrosion part and extracts only a magnetic sensor output signal from a healthy part. Then a divider 16 compares a reference voltage ER from a reference voltage generation part 15 with the output voltage EB of the magnetic sensor output signal of the healthy part extracted by the LPF and calculates and outputs a compensating voltage EK=ER/EB. Then the output voltage E1 of the signal Si is multiplied by the compensating voltage EK to compensate the output voltage E1, and consequently the variance in detection sensitivity for pitting corrosion is compensated automatically to improve the flaw detection accuracy.

Title: Cordless phone system
Inventor: MANIYUERU APURATSUTSU
IPC: H04M1/72502
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To improve the noise performance of a cordless telephone system by providing a band switching type front end which divides an assigned full band width into two bands which only require parts of the full band width. SOLUTION: RF signals received by means of an antenna are coupled with a mixer M1 provided in an RF and IF processor 120 from the secondary winding of a transformer TF1. When a higher band is selected, the transistor Q2 of a front end band switching circuit 100 is nonconducted and the transformer TF1 is tuned to the center frequency of the higher band. When a lower band is to be selected, a controller 130 conducts the switching transistor Q2 by impressing a control signal upon the node between base resistors R3 and R4. Consequently, a capacitor C3 is connected between parts of the primary winding of the transformer TF1 and the resonance frequency of the transformer TF1 drops to a frequency which is nearly equal to the center frequency of the lower band.
