Title: Fsk reception device
Inventor: YOKOAJIRO YOSHIYUKI
IPC: H04B1/30
Filed: 1994-11-04
Abstract: PURPOSE: To detect deviation of an intermediate frequency signal with simple constitution and control a local oscillation frequency by correcting an oscillation frequency in the direction wherein the difference between the counting result of a pulse quantity measuring means and the predetermined reference number of pulses becomes 0. CONSTITUTION: When the output of a band-pass filter 14 is larger than a specific level, a detection means 17 generates an output and the pulse quantity measuring means 18 is actuated. Then the number of pulses outputted from a pulse waveform shaping means 15 is measured for a certain predetermined time. Here, the shaping means 15 amplifies the output of the band-pass filter 14 and converts it into a pulse waveform by using a comparator. A frequency-voltage converting means 16 converts the frequency variation of the input into voltage variation and imposes FSK demodulation, and the demodulated signal is outputted to an output terminal 20. The number of pulses measured by the measuring means 18, on the other hand, is inputted to a frequency correcting means 19 to calculate an error in the predetermined reference number of pulses.  Then a control voltage corresponding to the error is generated at the filter 14 to eliminate the error.

Title: Friction clutch
Inventor: BEITLER HUBERT
IPC: F16D13/75
Filed: 1998-08-21
Abstract: PROBLEM TO BE SOLVED: To provide an operation characteristic of a clutch unrelated to abrasion with a simple structure by offsetting a change in pressing force of a disc spring caused according to abrasion of a clutch disc. SOLUTION: A disc spring now forms a cone having a sharp conical shape by an increase in an axial directional interval between the annular support part existing on a pressing plate and the housing side support part existing in an annular area, so that large pressing force is generated. An increase in this pressing force is offset by compression of an offset spring 28. This compression of the spring 28 is generated by moving an engaging releasing pipe 30 in an offset range of the spring 28 to the transmission device 3 side by the sharp conical shape of the disc spring 12 having an annular range of the properly large axial directional length. At engaging/releasing time of a clutch, this spring 28 extends by the parallel action of operation force 33 to offset an increase in pressing spring force 33 on the basis of abrasion by reversal thereby.  When a preload is applied to the offset spring 28, a stopper 29 is useful as the abutting part and the support part of the engaging releasing pipe 30 by limiting a spring stroke to extend the spring 28.

Title: Cryogenic air distillation method for producing argon
IPC: F25J3/04
Filed: 1992-10-12
Abstract: PURPOSE: To improve recovering rate of argon by a method, wherein only one portion of a condensing duty of a crude argon distillation tower is realized by low temperature, obtained by evaporating one part of liquid oxygen from the bottom of a low-pressure distillation tower under reduced pressure. CONSTITUTION: Only one portion of the required amount of production of gaseous oxygen is extracted from a low-pressure tower through a flow 195. The additional amount of liquid oxygen is obtained by reducing the pressure of a flow 159 into the pressure of a flow 160 and having it evaporated by the counter flow against the flow of condensed part of the top (a flow 96) of a crude argon tower portion 135. Subsequently, a flow of evaporated oxygen 161 is heated by semi-coolers 126, 127 and a main heat exchanger 105, then, is compressed by a compressor 165 and is joined with a flow 167 to obtain the flow of gaseous oxygen product, after cooling the same in a cooler 164 with cooling water. The conversion from liquid oxygen flow 159 to the gaseous oxygen flow 161 due to boiling in a boiler/condenser 128 satisfies only one portion of the condensing duty ratio in the crude argon tower 135.  Accordingly, the recovering rate of argon can be improved effectively.

Title: Image spectrum analysis instrument
Inventor: NAGASHIMA YOSHITAKE
IPC: H04N7/18
Filed: 1986-11-18
Abstract: PURPOSE:To reduce the size and weight of an instrument by converting a video signal to parallel light and converting the light to a frequency by Fourier transformation, then subjecting the frequency to filter processing. CONSTITUTION:The video signal which is a two-dimensional signal is inputted via a driving circuit 5 to a display element 3 of a transmission type and the laser light from a laser diode 1 is converted to the parallel light by a collimator lens 2. The parallel light is made incident to the element 3. The laser light past the element 3 is converted by a lens 4 for Fourier transformation and is outputted to the position of a display element 6 of a transmission type as a space filter. The element 6 outputs the signal light corresponding to the energy of the transmitted light. The high-speed processing is thus permitted and since the instrument operates on low electric power consumption, the size and weight of the instrument are reduced.
