IPC: H03G3/20
Filed: 1978-11-10
Abstract: PURPOSE:To increase apparent sensitivity by decreasing the lowest intensity of an operation electric field by automatically changing gains of an AGC amplifier circuit over by using a diode in a negative feedback circuit. CONSTITUTION:A high frequency signal from an antenna is selected by tuning circuit 1 and converted by mixing oscillation circuit 2 into an intermediate frequency signal, which is amplified by intermediate frequency amplifier circuit 3 and then detected by detection circuit 4. Its detection output is amplified by sound signal amplifier circuit 13 and its alternating-current component is led out from sound signal output terminal 6. The direct-current component, on the other hand, is imputted to AGC amplifier circuit 9 by way of sound-signal removing filter 7. Through the operation of negative feedback circuit 12, AGC amplifier circuit 9 allows output voltage Vin and voltage VAGC of AGC line 8 to bear non-linearity. Namely, when VAGC is high, diode 10 and Zener diode 11 conduct to provide much negative feedback and when Vin is high, only a little negative feedback is provided to the contrary.

Filed: 1978-11-10
Abstract: PURPOSE: To provide an arrangement for silencer, in which end portion of exhaust pipe is opened in a rotary cylinder formed with a multiplicity of apertures and incorporating a screw shaft so as to produce turbulence of exhaust gas in the rotary cylinder and to thereby promote interference of sound waves, whereby it is enabled to lower the noise level effectively.  
     CONSTITUTION: Casing 1 constituting an exhaust silencer is connected with front exhaust pipe 2 and rear exhaust pipe 3. A fixed cylinder 4 formed with a multiplicity of apertures is disposed in the casing 1, and on the inside of this fixed cylinder 4, there is further provided a rotary cylinder 5 also formed with a multiplicity of apertures and having a screw shaft 6 fixed to the same. With such an arrangement, when exhaust gas is introduced from front exhaust pipe 2 into the rotary cylinder 5, screw shaft 6 and also rotary cylinder 5 are turned by exhaust pressure and turbulence of exhaust gas is produced in the cylinder 5, so that interference of sound waves is promoted. Pressure of exhaust gas discharged to the fixed cylinder 4 is fairly reduced, so that it is discharged into the atmosphere with its noise level being lowered considerably. Thus, in accordance with the present invention, problems of noises produced by exhaust gas can be solved by use of exhaust pressure.

The peak powder is changed by the exchange of the laser heads of various time widths. The absorption coefft. of light to a working object or the focal depth is changed by the conversion of laser wavelength. Therminal diffusion and the processing impact to the periphery, etc., are controlled and the influence on processing depth and processing substrate is suppressed. The optimum processing according to the working object is thus availablie.

Title: Image processor
Inventor: KOHAMA SADAAKI
IPC: G06T1/00
Filed: 1987-06-03
Abstract: PURPOSE:To prevent the overflow of a frame memory from being generated, by adding a value multiplied by (N-1)/N (N represents a scheduled number of sheets of estimation) and a new image value on the image value of the frame memory, and storing again it in the frame memory. CONSTITUTION:When a control part 7 recognizes the fact that the number of image computing sheets arrives at a prescribed number N by the counting of an image signal delivery start signal sent from an image signal source 8 at every picture, the control part 7 sends data 1 immediately to the input C of a data selector 10, and transfers the output of a multiplier 9 to the minus input of a digital adder 2. Then, since image estimation from an (N+1)-th sheet is performed in such a way that the image value read out from the frame memory 1 is multiplied by a coefficient (N-1)/N and a result in which the new image value is added on it is re-stored in the frame memory 1, no overflow of the frame memory 1 is generated because no number of sheets of the estimation changes even when any number of sheets of images are inputted newly.

Abstract: PROBLEM TO BE SOLVED: To absorb a relative deformation caused by the difference in natural period even when it occurs at an underground portion by substituting part of the ground region spread between adjacent structural bodies with the prescribed deformation absorbing region. SOLUTION: The soft ground 3 in the ground region spread between a structural body 1 and a structural body 2 is dug down, and a buffer material 8 of foam styrol is filled in the removed space 11 to form a deformation absorption region 4.

The underground portions of the structural bodies 1, 2 are not broken at the time of an enormous earthquake, and healthiness is maintained. The vibration by the earthquake is damped by the deformation absorption region 4 and is quickly converged.
