Title: Optical device
Inventor: AOKI SATOSHI
IPC: G01M11/02
Filed: 1982-04-21
Abstract: PURPOSE:To remove simply the rear diffraction light power at the end section of incidence of a light transmission route by using a self focusing lens that is ground obliquely at the end face of one side. CONSTITUTION:The emission light 10 of laser is made parallel by a lens 11 and shined again to a light collecting fiber 12. A self focusing lens 22 has a diameter that is more than twice the diameters of other lenses and its end face on one side is ground obliquely with about 5 deg. inclination. The reflection at the end face of the lens 22 that is produced by the difference of refractive indices of matching oil 14 and the lens 22 is off the optical axis. The light that is directed into the lens is collected through a light route 24 and goes into the fiber 12. At this time, reflection is produced at the end face 21 of the lens by the difference of refractive indices of matching oil 15 that has the same refractive index as the fiber and the lens, and it passes through a light route 25 and diffused at a rough surface 23 and the diffused light is not received. The matching oil 14 and a beam splitter 13 have the same refractive index, and the light received at APD 7 becomes only diffused light that turns back from the fiber.

Title: Expansion valve for room cooler
IPC: F25B41/06
Filed: 1992-03-23
Abstract: PURPOSE:To circulate a minimum necessary amount of refrigerant even when a load is reduced since a predetermined amount or more of lubricating oil is always supplied to a compressor and to remove a thermal loss. CONSTITUTION:A bypass passage 60 is formed through a throttle valve 42, and its inlet 62 is so constructed as to gradually increase an opening area as the valve 42 rises. Accordingly, when a load is gradually reduced and a quantity of refrigerant which does not pass the passage 60 is decreased less than a minimum necessary amount, its insufficient amount of refrigerant can be guided to a throttle port 34 through the passage 60. When the load is a predetermined value or less, the quantity of refrigerant to be fed from an expansion valve can be kept constant at the minimum necessary level.

Abstract: PURPOSE: To obtain the same phase control state in arbitrary regions by selecting a commercial power source frequency and selecting a trigger phase set time determined on a basis of the selected frequency above or a time, which is obrained by multiplying or dividing this trigger phase set time by factor 5/6, on a basis of selection set signals of the power source frequency.  
     CONSTITUTION: Commercial power source 3, frequency selection swtich 8 and a CPU are operated under 60 Hz. In the CPU, zero-crossing signal 4 is received to detect a zero-crossing time. Time t by which the half cycle of power source 3 is segmented into the proper number of equal intervals is set to the CPU previously, and the number of a segment of the power source phase after which an input digital signal instructs the turning-on of switch element 1 is discriminated, and a trigger signal is given to driving circuit 7 at a designated trigger time. The CPU stores adjusteing time t/5 obtained by subtracting set time t from time 6t/5; and when switch 8 selects 50 Hz and 60 Hz is rejected, this is discriminated just after the measurement completion of time t, and the time of measurement completion of time t/5 is defined as a triggerrable time for 50 Hz. Thus, a unit which can be used for 50 and 60 Hz regions commonly can be obtained.

Title: Receiver
IPC: H04L27/22
Filed: 1992-03-24
Abstract: PURPOSE:To demodulate data in an excellent way even when delay dispersion is in existence or not in the reception data by controlling equalization at an equalizer depending on the result of discrimination by a circuit discriminating delay dispersion of reception data. CONSTITUTION:When a delay dispersion discrimination circuit 3 discriminates it that a signal with delay dispersion obtained at an output terminal is received, equalization processing at an equalizer 2 is implemented, a moving contact 4m of a changeover switch 4 is thrown to the position of a 1st fixed contact 4a and a reception signal subject to equalizing processing by the equalizer 2 is fed to a poststage circuit. When the delay dispersion discrimination circuit 3 discriminates it that a signal without delay dispersion obtained at an output terminal is received, the equalization processing at the equalizer 2 is stopped, the moving contact 4m of the changeover switch 4 is thrown to the position of a 2nd fixed contact 4b and a reception signal not subject to equalizing processing is fed to the poststage circuit. Then the reception data obtained at the moving contact 4m of the changeover switch 4 are fed to a DQPSK demodulation circuit 5, in which the reception data subject to pi/4 shift DQPSK modulation is demodulated.

Abstract: PURPOSE:To prevent the overload operation of a power amplifier and the continuity of discharge for arrestor, etc., by performing the detection of reflection independently of the phase difference between a load current and a load voltage and the variance of current amplitude. CONSTITUTION:When the load impedance is in variance toward the output current of a power amplifier to be increased, a positive voltage is produced across a resistor 52, and when fluctuated toward the output current to be decreased, a positive voltage is produced across a resistor 53, and a logical output is obtained by the reference voltage and a voltage comparator 55 by selecting larger voltage through diodes 48 and 49. On the other hand, since high frequency transformers 36, 37 and diodes 381-384 act as a phase detector, a voltage in proportion to the output voltage and the phase difference of the output current is produced across resistors 391, 392, and if a positive voltage is produced at the resistor 391 at a leading phase, a positive voltage is produced at the resistor 392 at lag phase. Further, a greater voltage is selected and it is compared with the reference voltage at the voltage comparator 54 to obtain an output.
