Title: Rotating drum of magnetic recording and reproducing device
Inventor: TSUNODA SUSUMU
IPC: G11B15/61
Filed: 1983-08-05
Abstract: PURPOSE:To reduce a loss of rotation by forming plural air holes which pierce a rotating drum between a surface where a magnetic head is fitted and a surface where no head is provided. CONSTITUTION:Four air holes 5 in the rotating drum 1 each consist of a through hole 5 which extends from the top surface to the reverse surface of the drum at about 30 deg. to the vertical axis and an expansion part 5b; the through hole 5 slants during the rotation of the rotating drum 1 in such a direction that the top surface side of the drum precedes the bottom surface side, and the expansion part 5b expands in the rotation direction along the circumferential wall of the rotating drum. Consequently, every opening part 5c is positioned in the middle between magnetic heads 4. Then, discharged air flows from the gap between the rotating drum and a fixed drum 2 to the surface of a magnetic tape 6 and air flows in from an air intake 11 as well; and both air flows are led to between the outer circumferential surface of the rotating drum 1 and the magnetic tape 6. Thus, an invariably stable air layer is formed and held.

Abstract: PURPOSE:To eliminate deformation caused by the release of a residual distortion generated during the molding of a container in a high temperature sterilization by performing a thermal solidification by heating under a tension. CONSTITUTION:A plug 26b is pressed on a sheet 2 and premolded. Then, the sheet 2 is put tight on the die inner wall 25a and undergoes a vacuum and pressure forming. After the adhesion, the sheet is held tight by compressed air operation for the time enough to release molding distortion depending on the heat of the mold. Then, the pressure in a container is lowered to a level free from possible expansion by the internal pressure even when the mold is opened and shrinkage by the heat shrinking force of the metal container. Then, while the pressure is kept at this level, the mold 25 is moved in the direction of the arrow D2 to open the mold. Then, the container is moved in the directions of the arrows C2 and E2 to be transferred to a cooling stage B and then, cooled down to the temperature free from possible deformation of the container with the removal of the internal pressure from outside with a cooler 22.

Title: Synchronous demodulator
Inventor: YOAHIMU BURIRUKA
IPC: H03D1/22
Filed: 1989-06-07
Abstract: PURPOSE: To suppress phase modulation due to interference by applying a DC voltage being a combined product received from a multiplier as a measured value of a frequency shift of a carrier signal with respect to a passing frequency from a filter circuit to the filter circuit as a variable for the control of the passing frequency. CONSTITUTION: A carrier signal fed from an input 1 to a multiplier 5 is in phase with a reference signal fed from a limiter 3. The reference signal is phase-shifted by 90 deg. by a phase shifter 4 in succession to the limiter 3 and the signal is fed to a multiplier 5, in which the signal is combined with a modulated carrier signal in terms of multiplication. Thus, a useful control signal is outputted to an output 7 of the multiplier 5. A Dc voltage having a value proportional to a shift of a carrier frequency from a maximum frequency at its frequency band of the filter circuit 2 with a prescribed frequency interval and in the vicinity of the frequency of the carrier signal is generated as a mixed product at the output 7. The DC voltage is fed to the filter circuit 2 as its control voltage. Thus, the reference signal without phase sift is obtained as a result.
