IPC: G01N27/62
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To enhance a resolving power in relation to measurement of a leak amount by clearly separating helium ions and trivalent nitrogen ions. SOLUTION: In constituting so that ions emitted from an ion source 2 are subjected to a magnetic deflection and helium ions He+ are brought with priority into an ion collector 4 arranged at a terminal end of an orbit specific to the helium ions He+, a diaphragm 9 is installed in the vicinity of a terminal end of the magnetic deflection. An orbit of each ion is set to converge to the vicinity of the diaphragm 9. Moreover, a slit 9a is formed to a position of the diaphragm 9 corresponding to a helium ion convergent part. Accordingly, helium ions He+ and trivalent nitrogen ions N3+ having proximate m/e values and adjacent orbital radii can be clearly separated.

Title: Electric current/pressure converter
Inventor: KIMURA ATSUSHI
IPC: F15B5/00
Filed: 1990-10-30
Abstract: PURPOSE:To attempt removal of the use of a high-precision high resistance for level shifting by generating a constant voltage in a constant voltage generat ing circuit through a first variable impedance element and generating an output chamber gas pressure by means of an actuator, and changing the electric current flowing in a second variable impedance element by a signal calculated from the gas pressure. CONSTITUTION:A reference voltage Er is generated in a Zener diode D3 connected in series to resistances R21, R22 between input terminals T1, T2. The voltage Er is inputted to a transistor Q9 connected in series to an actuator 18 through an operational amplifier Q8 together with a signal electric current Ip. The back pressure of a nozzle 21 is changed by displacement of the flapper 20 of the actuator 18 to output an air pressure signal P1 to an output terminal 23 through a pilot relay 22. A transistor Q16 is operated by the air pressure signal P1 through a pressure sensor 25 and operational amplifiers Q12-Q15 so that the air pressure signal P1 may correspond to the signal electric current Ip. Consequently, constant voltage does not vary largely even in the transient situation thereby the stability is improved.

Abstract: PURPOSE:To measure the level with high accuracy even in a minimum bit by sampling a high level and a low level of a signal to be tested individually, holding the result and using a voltage measurement means so as to measure the difference voltage. CONSTITUTION:A couple of sample-and-hold circuits 5, 6 comprise analog switches 5a, 6a and hold capacitors 5b, 6b holding a voltage level obtained via them.

Thus, the voltage between the lines l1 and l2 is a difference voltage Vx between the outputs VH and VL and the the voltage of the LSB of the converter 2 is directly measured by measuring the voltage.

Title: Optical transmitter
Inventor: FURUSAWA SATOSHI
IPC: H04B10/54
Filed: 1994-11-28
Abstract: PURPOSE: To automatically compensate dispersion without depending on a transmission distance and to improve the flexibility of an optical transmitter by performing a control imparting delay for at least one optical wavelength so that the propagation delay time difference of the inter-optical waves due to dispersion may be zero. CONSTITUTION: The control signal generation means 13 of a dispersion compensation means 8 sweeps delay time within the range of the variable delay time of an optical delay means 5 by a control signal for a period when a detection means 12 detects the generation of the optical propagation delay time difference of wavelengths ν1 and ν0 When the fact that propagation delay time difference is zero is detected by this delay operation, the delay time of the means 5 is fixed. As a result, the propagation delay time difference between the optical wavelengths due to the wavelength dispersion generated because an optical digital signal 101 propagates a dispersible medium 200 is detected by the peak level difference of the signals detecting and amplifying the optical signal which enters the means 8.  Because the delay time of the light of one optical wavelength is selectively controlled based on the detection result and a dispersion compensation is automatically performed, the original optical signal 101 becomes possible to be reproduced by the output stage of an optical coupler 6 without depending on the transmission distance.
