Title: Surface analyzer
Inventor: NAGAI KAZUTOSHI
IPC: H01J37/252
Filed: 1984-12-21
Abstract: PURPOSE:To enable secondary particles to be subjected to mass spectrography regardless of whether they are atoms or ions by passing the secondary particles through an electric charge converter consisting of an encircling case and a circular filament for producing thermions which has an electric potential slightly positive to that of the encircling case to convert the secondary particles into negatively charged ions. CONSTITUTION:In the surface analyzer of this invention, a beam 17 from an ion source 16 strikes against a sample 3 to produce secondary particles 9 which then pass through an electric charge converter 10 before entering a mass spectrometer 5. The electric charge converter 10 consists of a cylindrical encircling case 12 and a circular filament 13 for producing thermions which is located inside the case 12. A voltage slightly negative to that of the filament 13 is applied to the case 12 to produce thermions which are then concentrated on the center of the filament 13 thereby producing an electron cloud. Therefore, among the secondary particles 9, negatively charged ions pass as they are through the converter 10 and positively charged ions and sputter atoms are converted into negatively charged ions while passing through the converter 10 before these negatively charged ions are subjected to pass spectrography. Consequently, the accuracy of mass spectrography can be increased.

Title: Reflection type microwave communication equipment
Inventor: OGATA AKIMITSU
IPC: H04B7/26
Filed: 1988-10-27
Abstract: PURPOSE:To obtain a microwave communication equipment performing a stable operation by receiving a microwave carrier from a main device by a data carrier part which holds registration data, and sending a reflected wave modulated by the registration data to the main device. CONSTITUTION:The data carrier(DC) part 200 which holds the registration data and the main device 100 are provided, and information transmission by a microwave is performed by receiving a microwave carrier wave A from the main device by the DC part 200, and sending the reflected wave B modulated by the registration data to the main device. Since the modulation of the reflected wave is performed by the modulation frequency signal of low frequency (50kHz, 30kHz) of the registration data and a subcarrier frequency signal of frequency (10MHz) remarkably higher than that, frequency conversion is performed by adding a carrier frequency as local oscillation when the reflected wave is received at the main device, and the modulation frequency component on one side of both side band wave signals is extracted by a band-pass filter, and the modulation frequency signal is extracted via those band-pass filters, and is demodulated, then, the registration data can be obtained. Thereby, the stable operation can be performed even under strict environment.
