Abstract: PURPOSE:To improve the sensitivity of a receiving circuit, by removing multiple spurious components of frequency nearly equal to reception carrier frequency in a transmitter and receiver used for a wireless interphone capable for duplex transmission. CONSTITUTION:On a receiving circuit side 5, reception is performed at desired reception carrier frequency fB through an antenna 2 and at a front end 11 which uses the 9-multiplication output of a multiplying circuit 10 which multiplies the reference frequency f0 of a reference oscillating circuit 1 as a local oscillation input, high frequency amplification and frequency conversion are carried out.

Title: Semiconductor optical filter and optical communication system using the same
Inventor: ONO TAKEO
IPC: H01S5/12
Filed: 1992-01-13
Abstract: PURPOSE:To obtain the semiconductor optical filter with which a wide range for tuning the selection wavelengths of the filter can be taken, the control to tune the filter is stably executed, the control is easy and the element production process is easy. CONSTITUTION:The semiconductor band-pass filter has a semiconductor laser structure of a distribution feedback type by gratings and amplifies and passes only the specific selection wavelength determined by the pitch of the gratings among incident beams. The saturation gain of the base level of an active layer 4 is smaller than the sum of the losses by the diffraction of the reflection gratings at the end face of the filter, absorption of the active layer itself, etc. The gratings are so formed as to generate the distribution feedback in the wavelength region where the single-pass gain by the base level of the quantum wells of the active layer 4 is large. The loss in this wavelength region is increased by forming the grating pitch so as to cause the distribution feedback by the diffraction of the second or higher order of the grating in this wavelength region at this time.

Abstract: PURPOSE:To provide stainless cast steel for cryogenic service which withstands use at an ultralow temp., and withstands corrosion such as pitting by sea water, etc. by contg. respectively prescribed ratios of C, Si, Mn, Cr, Ni and Mo and specifying an amt. of delta ferrite. CONSTITUTION:Stainless cast steel for cryogenic service contains, by weight, <=0.08% C, <=2.0% Si, <=2.0% Mn, 18.0-26.0% Cr, 5.0-16.0% Ni and 0.5-5.0% Mo, and contains 10-40vol% delta ferrite. The above-described amt. of ferrite phase is precipitated in the casting structure of said cast steel by which the Ni contained in austenite is made 1.2-1.3 times the average content of Ni in the alloy. The gamma-alpha'transformation can thus be suppressed with the addition of a low content of Ni and the deformation is consequently prevented; in addition, castability is considerably improved. The cast steel is stable at an ultralow temp. even if it is not subjected to a sub-zero treatment and moreover it is highly resistant to corrosion, more particularly to pitting.
