IPC: G01M7/02
Filed: 1993-11-19
Abstract: PURPOSE:To realize high frequency vibration test by passing a control amount detection signal through a BPF having pass band equal to the frequency of a vibration command, subjecting the AC signal to A/D conversion to determine the amplitude of control amount, and then generating an operation signal using the difference of amplitude between the vibration command and the control amount. CONSTITUTION:A signal (d) is detected from the vibration of an IC to be tested by means of a sensor 4a and a detecting section 4 and fed to a BPF 5A which also receives a test vibration frequency a2 from a frequency command input section and passes the frequency a2. Output front the BPF 5A is fed to an amplitude detecting function 5B where it is subjected to A/D conversion by a function similar to full-wave rectification and the amplitude component of frequency a2 in the signal (d) is delivered, as a feedback value (b), to a difference detecting section 2. A test amplitude value a. is fed from an amplitude command input section A1 to a detecting section 2 and the difference DELTAa between the amplitude value a1 and the feedback value (b) is amplified by a difference amplifier 3A and fed to an operating signal generating function 3B. The function 3B comprises an inverse Fourier transform unit and delivers an operation signal (c) for minimizing the difference DELTAa at the frequency a2.

Title: Noninterference ss multiplex communication system
Inventor: TSUCHIDA NUIO
IPC: H04B1/7103
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To solve a problem that a conventional noninterference SS multiplex communication system has incurred a high cost when this system is put into practical use because this system has required an inner-channel interference elimination circuit employing a comparatively expensive double balanced modulator or multiplier circuit for spread/inverse spread processing. SOLUTION: In the noninterference SS multiplex communication system that employs only gates for its spread/inverse spread processing, 2nd inverse spread processing is conducted by using an inverted code in the case of gate-off for the 1st inverse spread processing using PN cods, the resulting signal and a signal of an ancillary circuit are added to the resulting signal of the 1st inverse spread processing to increase the reception sensitivity by 6 dB. Furthermore, a synchronizing signal with the same period as the spread code is transmitted while changing a phase or a frequency of the carrier and the synchronizing signal received at a receiver side passes through an integrator to obtain enhanced noise immunity.  Thus, he application range of a communication unit can be extended, the noise immunity is considerably enhanced, the transmission power is reduced, the spread/inverse spread processing can be attained by using the gate circuit only, the synchronization is easily acquired and this system can be put into practical use with a simple circuitry.
