Title: Signal spectrum measuring device
Inventor: AKITA SHINICHI
IPC: G01R23/165
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for measurement of all bands and make the measurement precise by switching the gain of GPF circuit and/or the gain of a peak hold circuit according to at least one switching of the central frequency of the pass band. SOLUTION: The frequency is set to f2=f1/2, f3=f1/4, fn=f1/2<n-1> , and the gain is set to A1=1, A2=2, An=2<n-1> . A capacitor is selected according to the central frequency of the pass band to switch the gain. One of capacitors Ci1-Cin is selected by one pair of analog switches Xi1-Xin. ON/OFF is performed according to control signals M1-Mn. When only the control signal Mn is active, a pair of switches X1n, X2n are simultaneously ON, the central frequency is set to the pass band of fn, and the gain is set to An. The measuring time of the pass bands of the central frequencies f1-fn can be set to the shortest measuring times, so that the whole measuring time can be thus shortened, and the precision can be also ensured with the shortest time necessary and sufficient for measurement.

Title: Wavelength measuring device for two-frequency laser light source
Inventor: UEDA MORIMASA
IPC: G01J9/02
Filed: 1996-07-12
Abstract: PROBLEM TO BE SOLVED: To make it possible to measure the change in difference of the respective frequencies of two waves without a long measuring time even when two waves are measured by making a plurality of the respective lights to be measured, which are outputted from a laser light source to be measured and have the difference polarizing angles to each other, interfere with reference light alternately. SOLUTION: A laser light source to be measured 1 emits two frequencies of orthogonal straight-line polarized lights. The first wave and the second wave of the light to be measured emitted from the light source 1 alternately pass a polarizing plate 2, which is continuously rotated with the optical-path axis as the rotary center. Both alternately passed waves are made to pass a λ/4-wavelength plate 3 and converted into the circular polarized lights. Furthermore, both waves are made to pass a polarizing plate 4, wherein the optical axis is set at the same angle as the polarizing angle of the reference light, converted into the linear polarized light having the same polarization angle as the reference light and made to interfere with the reference light at a beam splitter 5 so as to generate beats.  The beats are received with a photodetector 6, and the outputs are counted with a counter 9. The counter 9 alternately counts the beat frequencies of the first wave and the second wave.

Abstract: PURPOSE:To obtain high reception sensitivity even in the receiving state where an optimum threshold value considerably fluctuating by generating a threshold voltage set in advance corresponding to the level of a signal beam and executing automatic control so that the threshold value of an identifying circuit can be set at the optimum value. CONSTITUTION:A light amplifier 10 inputs and amplifies signal light 1, the signal light amplified by a light amplifier element 2a is converted to an electric signal, the electric signal is amplified to a prescribed voltage level by amplifiers 3 and 4, and the amplified output is compared with a set threshold voltage so as to identify the mark and space of the signal light by an identifying circuit 8. When the level detecting value of the input signal light is low, a threshold value control circuit 18 variably controls the threshold voltage, which is set to the identifying circuit 8, in a direction close to an intermediate level between the mark level of the signal light and a space level and when the signal light level is high, the threshold voltage is controlled in a direction close to the space level of the signal light. Thus, even in the receiving state where the optimum threshold value fluctuates considerably, high reception sensitivity can be obtained.

Title: Method and device for calculation treatment of radioactive solid waste
Inventor: NAKAYAMA JUNPEI
IPC: G21F9/32
Filed: 1996-08-01
Abstract: PROBLEM TO BE SOLVED: To enable stable and safe operation even when inorganic and organic substances are intermingled by installing a water cooling jacket to restrain the heating quantity for a waste and cooling the atmosphere around it to curb the rate of temperature rise. SOLUTION: A heating chamber is constituted of a water cooling jacket 1 and an induction coil 2 so as to restrain the heating quantity for a waste X and cool the atmosphere around them. Then, the temperature of the waste X in the jacket 1 is raised slowly through the induction heating of the coil 2 while it is monitored by a waste temperature detector 13. Subsequently, the concentration of oxygen and carbon dioxide contained in a pyrolysis gas of organic substances in the waste X is monitored by an oxygen concentration detector 11 and a carbon dioxide concentration detector 12. In this process, a coil 2 is operated to stop or weaken the heating, when it is judged that the oxygen concentration is lowered abnormally to cause incomplete combustion.  Thereupon, the heating is finished by judging that a calculation treatment for pyrolyzing organic substances has finished at the time when the concentration of carbon dioxide has lowered from a fluctuating condition to a steady state.

Filed: 1983-10-31
Abstract: PURPOSE:To improve load capacity and to relieve sliding resitance, by a method wherein a sliding part is divided in the direction of rotation into plural chambers, and an oil pressure can be introduced in each chamber through a check valve. CONSTITUTION:By feeding pressure oil through an oil feed hole 5 and distributing holes 6 in a rotary shaft S, a check valve 8 is opened to almost fill each of chambers I -IV with the pressure oil flowing between a head part 9b of an oil film thickness regulating valve 9, which is opened, and a funnel-shaped part 7b. In each of the chambers I -IV, when the chamber is in a high pressure, the check valve 8 is closed to maintain a high pressure, and when it is brought into a negative pressure, the check valve 8 is opened to introduce the pressure oil therein. This causes a high-pressure thick film to be formed in each of the chambers I -IV, and enables support of the rotary shaft S with a minimum of sliding resistance.
