Title: No-signal detecting circuit
Inventor: TAKEHIRA MITSUSHI
IPC: H04B17/00
Filed: 1985-08-31
Abstract: PURPOSE:To detect easily no-signal with a good S/N by applying a frequency on the outside of a transmission signal band onto a reception signal to amplify the signal and detecting a ratio of a frequency component included in this amplified waveform. CONSTITUTION:An avalanche diode (APD) 1 receives an optical signal and converts it to an electric signal. A specific frequency signal is inputted to the control part of a high voltage generating circuit 8 through an oscillator 14 and is added to the transmission signal. This frequency signal is amplified together with the transmission signal and is obtained as a frequency component inputted from the oscillator 14 through a band pass filter 9. The output of the first peak detecting circuit 5 and that of the second peak detecting circuit 11 which detects the peak value of the output of the filter 9 are compared with each other by a comparing circuit 12 to detect the S/N of the specific frequency component to the transmission signal. Thus, the reception optical level is discriminated to detect no-signal well.

Title: Satellite communication system
Inventor: AKASAKI KOJI
IPC: H04B7/208
Filed: 1988-07-30
Abstract: PURPOSE:To detect an abnormal call immediately due to simultaneous callings by plural stations by using plural earth stations applying transmission and reception via a communication satellite and setting different frequencies used for the transmission and reception to the same frequency tentatively. CONSTITUTION:For the information communication by plural earth stations via a communication satellite, a frequency F1 is assigned to a transmission line and a frequency F2 is allocated to a reception line normally. An earth station starting calling uses the reception frequency F2 for the transmission line tentatively in the timing 6 to send a cease pulse 1 and a station identification number 2. They are monitored by other earth stations as reception signal pulses 3, 4. In this case, when the other earth stations reach calling simultaneously, the signals 3, 4 cause abnormal reception due to the collision of carriers. When the monitor tells no fault, the transmission frequency is restored to the F1 in the timing 7. Thus, the abnormity due to simultaneous calling by plural stations is detected instantly, the simultaneous calling is prevented and the efficiency in the satellite communication is improved.

Title: Semiconductor light emitting element
Inventor: MATSUDA MANABU
IPC: H01L33/10
Filed: 1989-07-25
Abstract: PURPOSE:To improve the title element in converting efficiency of injecting current into light and in light enclosing efficiency into a waveguide so as to accurately set a wave guiding mode by tilting one end face of the waveguide having a striped pattern against the direction perpendicular to the light guiding direction of the waveguide. CONSTITUTION:At least one of the end faces of a light emitting diode 1 which inputs and outputs light is tilted against the longitudinal direction of stripes so that light cannot make Fabry-Perot resonance in an active layer 3. Since the light advancing through a waveguide does not make oscillation in the Fabry- Perot mode and the waveguide formed of the layer 3, a clad layer 4, etc., employs a buried structure, enclosing effect of injected carriers and light waves is achieved and high-output operations is realized. Since the stripes of the layers 3 and 4, etc., are formed along the orientation of the crystal, the vertical surface of the waveguide becomes smooth and leakage of light is reduced in guiding mode, resulting in an accurate light guiding mode. When light is taken out from the diode 1, an optical fiber is connected perpendicularly to the surface direction at the output terminal.

Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To impart the same operational feeling as existing accelerator pedals to an accelerator pedal connected by means of a shorter wire cable with a rotary shaft for directly or indirectly driving a power control device such as an intake throttle valve with no drop resulted in the leg power on the accelerator pedal. SOLUTION: A plate member 38 is fixed on a rotary shaft 9, and a spring member 27 continuously and elastically presses a pressure member 29 on the surface of the plate member 38 to compensate for a reduction in the leg power on the accelerator pedal by the frictional force caused thereby. The pressure member 29 is supported on the device to be axially movable through the fitting of its projections 30 into fitting grooves 31. The corotation of the pressure member 29 with the plate member 38 due to the circumferential clearance between the projections 30 and the fitting grooves 31 is prevented by springs 40 which bring one surfaces of the projections and the grooves into contact with each other, to thereby eliminate abnormal feelings of the accelerator pedal in the operational start thereof.

Title: Porous material, sound absorbing and insulating material and damping material using the material
Inventor: IMAGAWA HIROSHI
IPC: E04B1/82
Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To enhance a sound absorbing and insulating effect and a damping effect in a wide region from a low frequency till a high frequency by specifying the spring constant and the air permeability of porous material to enable both of the internal frictional force and the air-flow-resistance of the porous material to act on a vibration damping. SOLUTION: The spring constant K of the porous material is set so that its reciprocal 1/K becomes 0.02 cm/kg to 1.0 cm/kg and preferably it becomes 0.04 cm/kg to 0.4 cm/kg. The vibration damping capacity in the low frequency region of the porous material can be enhanced by setting the reciprocal 1/K of the spring constant K within such a range. Moreover, the air permeability of the material is set to 1 cc/cm<2> sec to 60 cc/cm<2> sec. An air-flow resistance at the time a sound wave and a vibration wave transmit the porous material can be made larger by setting the air permeability within such a range and, moreover, a conversion efficiency from acoustic energy to thermal energy which comes from this can be enhanced.
