Title: Signal transmitter
Inventor: TAI SHIYUUICHI
IPC: H04B10/00
Filed: 1980-05-13
Abstract: PURPOSE:To eliminate the effect due to a change of temperature, by multiplexing the wave to be modulated obtained by modulating an electric signal with the 1st carrier frequency and a signal having the 2nd carrier frequency as it is and then transmitting and demodulating the multiplied signal. CONSTITUTION:The electric signal V supplied from a signal source 1 is supplied to an FM modulator 2a, and a carrier frequency f1 is modulated to deliver a wave to be modulated and having a modulated frequency of f1+ or -DELTAf. On the other hand, the input terminal of an FM modulator 2b is earthed to deliver a carrier wave f2 as it is. Such wave to be modulated and the carrier wave are multiplexed and led to an LED driving circuit 9 to be converted into an optical signal through an LED8. This optical signal is transmitted to a PIN photodiode 11 via an optical fiber 10 to be converted again into an electric signal. This electric signal is amplified by an amplifier 12 and receives a separation of signal waves of frequencies f1+DELTAf and f2 through filters 13a and 13b, respectively. These signal waves are demodulated by FM demodulators 3a and 3b, and the difference between two input signals is amplified by a differential amplifier 14.

Title: Probe for scan type tunneling microscope with auxiliary electrode
Inventor: NAKAGAWA HIDEMOTO
IPC: G01N37/00
Filed: 1989-03-17
Abstract: PURPOSE:To reduce measurement disturbance due to an adsorbed ion by providing >=1 auxiliary electrodes nearby the probe and controlling the electric field nearby the probe with a voltage applied to the auxiliary electrodes. CONSTITUTION:An auxiliary electrode 3 is provided at the periphery of the probe 1 through an insulator 2. Further, when the tip of the probe 1 is cleaned by electric field ion radiation, a pulsating voltage which is necessary for the electric field ion radiation is applied the probe 1 and electrode 3 in a vacuum state to dissocinate adsorbed ions with the electric field. Then when a leak current is reduced in an electrolytic solution, the same potential with the probe 1 is applied to the electrode 3 and then the leak current from the flank of the probe 1 to the solution is reduced greatly because the level of the leak current is proportional to the density of lines of electric force. Then if movable adsorbed ions are present on the surface of a sample 4 when a measurement is taken in an atmosphere, a large voltage having the opposite polarity from the adsorbed ions is applied to the electrode 3 and then no influence is exerted upon the measurement of a tunneling current at the tip of the probe 1.
