Abstract: PURPOSE:To determine the phase difference of the low frequency transmitted or received for accurate distance by detecting and extracting the modulated low frequency from the ultrasonic wave modulated with low frequency in the measurement  of distance to a flat reflection body including the altitude from the water surface. CONSTITUTION:A super high frequency (40kHz) obtained from the oscillator OSC1 is modulated with a low frequency (50Hz) obtained from the oscillator 2 and the modulated output is emitted with a transmitting element 1. The signal received with a receiving element 2 is detected and amplified with a low frequency of 50Hz by means of a detection amplifier DBA incorporated into the band width filter and then, converted into a square wave with a zero-crossing detector ZCD2. On the other hand, after adjusted in the phase with a phase adjusting device PS, the oscillated frequency of 50Hz from the oscillator 2 is provided to the zero-crossing detector ZCD1 to be converted into a square wave. The output of both the detectors ZCD 1 and 2 produces a signal of pulse width corresponding to the phase difference phi in an exclusive ''or'' circuit EX-OR.

Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to quantitatively analyze a sample, specially polonium(Po) impurities, in shorter time, by coprecipitating Po with a substance coprecipitable with Po and concentrating them after they are separated. SOLUTION: This sample for analysis of impurities in phosphoric acid is prepared by treating the phosphoric acid sample with a substance coprecipitable with polonium(Po) contained in the acid.

Title: Uv detector for liquid chromatograph
Inventor: SHIKAMATA TAKESHI
IPC: G01N30/74
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To obtain a UV detector which enhances the utilization efficiency of incident light and which can restrain a base line from being changed even when the refractive index of a solvent is changed by a method wherein a sample chamber in a flow cell is formed to be a conical trapezoidal shape which is reduced toward the side of a light exit. SOLUTION: In a flow cell 10, transparent plates 13 are attached respectively to both end faces in the axial direction of a cylindrical flow cell block 12 provided with a sample chamber 11 which is passed through in the axial direction. Light enters the sample chamber 11 via the window plate 13 from an opening 14a in a retention plate 14 on one side, and it is radiated, via an opening 14a, from the window plate 13 on the opposite side. A sample (a solvent) enters from an inflow passage 15a, it advances inside the sample chamber 11 to the axial direction, and it is then discharged to the outside through an outflow passage 15b. The inner shape of the sample chamber 11 is formed to be a conical trapezoidal shape, and it is formed in such a way that the side of a light exit is thin. Thereby, the three-dimensional angle of incident light can be made large, the utilization efficiency of the incident light on the flow cell 10 is increased, and it is possible to restrain a base line from being changed even when the refractive index of the solvent flowing in the flow cell 10 is changed.

Title: Wire electric discharge machine
Inventor: KAMIGUCHI MASAO
IPC: B23H7/02
Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To improve the rate of machining and to avoid dispersion in oversize machining even if a work varies in thickness by preventing a disconnection of a wire electrode. SOLUTION: A machining-distance arithmetic and logic unit 11 outputs a signal after every machining of a preset distance Δx. Between such output signals, a main pulse generator 1 generates main pulses for electric discharge machining, which are counted up by a main-pulse-number store unit 12. Upon receiving every signal, a plate-thickness arithmetic and logic unit 14 processes a reference main pulse number stored in a reference main-pulse-number store unit 13 for the machining of a reference plate thickness and a main pulse number stored in the main-pulse-number store unit 12 to compute the rate of change in plate thickness.  Depending on the rate of plate thickness change, a discharge- stopping-time control unit 15 varies the stopping time of the voltage applied between a wire electrode 4 and a work to thereby hold the machining current density unchanged before and after a change in plate thickness. This method prevents a wire disconnection caused by a change in plate thickness to thus avoid dispersion in oversize machining and also speed up the rate of machining.
