IPC: H04B10/00
Filed: 1979-10-29
Abstract: PURPOSE:To prevent the deterioration due to interference, by cancelling the detour interference components from an optical transmitter of the station even if an optical distributor of a simple constitution is used. CONSTITUTION:An optical distributor 31 performs transmission and reception of optical signal. To the signal received at the optical distributor, the reflection signal for the signal transmitted from a transmitter 11 is included. The signal received is fed to an optical receiver 21, and a part of power of the said reflection signal is branched at an optical coupler 41 and it is converted into electric signal at an optical detector 51. Further, by subtracting the signal having the reflection component received at the optical receiver 21 from the reflection signal detected at the photodetector 51, the reception signal rejecting the reflection component of the station can be obtained.

Moreover, the specific permeability mu of a soft magnetic core member being a component of the magnetic core 3 is selected to be larger than 2000. Thus, even in the case of the magnetic head of a narrow track width whose track width is <=5mum, a reproduction efficiency of >=60% is realized similarly to the case of the magnetic head whose track width >=5mum such as 10mum.

Abstract: PURPOSE:To uniformly and efficiently cool a molded article, enhance adhesive properties of the same to a forming mold, and produce efficiently the high-quality molded article by softening a resin sheet under heating, pressurizing said sheet with compressed gas, and cooling the same under the condition where the sheet is allowed to closely adhere to the forming mold. CONSTITUTION:Air on the lower face side of a sheet 2 is sucked in an air suction tube 12 and exhausted through air ports 15,... and, simultaneously, a liquefied gas refrigerant is supplied into an airpressure box 10 through an inlet pipe. Since a space between the air-pressure box 10 and the sheet 2 is kept substantially airtight, internal pressure is rapidly increased together with gasification of the liquefied gas refrigerant, and the sheet 2 is strongly pressed against the forming face of a forming mold 9, so that the surface shape and condition of the forming mold are imparted to the sheet 2. Further, the sheet 2 is uniformly quenched as a whole by the liquefied gas refrigerant simultaneously with this forming and is hardened while keeping the imparted shape. Upon completion of the forming and cooling, pressure in the air- pressure box 10 is reduced, and a table 7 is brought down while the air-pressure box is lifted up so that the formed sheet is released from the forming mold, and the molded article 15 taken out of said mold.
