Title: Method for stabilizing frequency of internal mirror type he-ne laser having 534-nm oscillating wavelength
Inventor: DEKI KYOICHI
IPC: H01S3/139
Filed: 1988-09-22
Abstract: PURPOSE:To stabilize the frequency of the title laser within a wide range by preventing inversion of polarization by impressing a specific static magnetic field upon the inside of the laser thin tube and, at the same time, by feedback-controlling the resonator length by utilizing the phase of the waveform of a recessed part produced at the center of the output waveform of the light component in an inherent polarizing direction having a high intensity as an error signal after detecting the phase at the time of three-longitudinal oscillating time when the light component is positioned in a specific state. CONSTITUTION:The resonator length of a laser tube LA is modulated by modulating the electric power supplied to a heater HE wound around the laser tube LA with signals from an audio frequency oscillator AFOSC. Then the differential signal of the recessed section waveform of the area A shown in the upper graph of the figure is obtained by phase-sensibly detecting the frequency component from the output light of the laser passing through a linearly polarizing plate LP1 place in the direction of the inherent polarizing direction C2 of the component by means of a lock-in amplifier LIA. The resonator length can be kept constant when the length is controlled by means of the heater HE by utilizing the linear slope section at the central part of the differentiating signal as an error signal. Therefore, the frequency of the laser can be stabilized.

IPC: H04W88/02
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To suitably assist how to reply in voice for the user in a telephone set with a voice reply function, in which a hands-free talk is started by giving a reply toward the telephone set. SOLUTION: A noise level around a master set and a slave set is detected and stored at the arrival of an incoming call (S10, S20). When no off-hook operation is made and a voice reply of 'hi' is started toward the master set or the slave set, a bar display is started on an LCD (S30-S50). After the lapse of a prescribed time, a blinking processing is applied to the bar display extending over a prescribed time (S60, S70). While blinking display of the bar is made, when the voice reply is stopped, a hands-free talk is started. While blink display of the bar is executed, when the voice replay is not stopped, bar display is stopped, and the processing is restored to the step S 30 (S80-S100).

Title: Method for measuring ion concentration, specific gravity or osmotic pressure of solution
Inventor: KAWANISHI TETSUAKI
IPC: G01N31/22
Filed: 1989-09-14
Abstract: PURPOSE:To easily and exactly measure an ion concn., sp. gr. and osmotic pressure by bringing a coloring material consisting of a dyestuff or dyestuff precursor having the solubility correlating with the ion concn. in a soln. into contact with the soln. to be measured. CONSTITUTION:The coloring material which consists of the dyestuff or dyestuff precursor and has the solubility changed by the ion concn. of the soln. is added into the soln. to be measured and the solubility of the coloring material in the soln. is detected, by which the ion concn. of the soln. is measured. Since the ion concn. correlates with the sp. gr. of the soln., the sp. gr. is measured accordingly. Since the osmotic pressure is proportional to the number of the particles of the solute in a specified volume of the solvent, the osmotic pressure correlates with the ion number, i.e. ion concn. in the electrolyte soln. The osmotic pressure is thereby measured. The ion concn., sp. gr. and the osmotic pressure are, therefore, exactly measured by the easy and simple operation.
