Title: Recording device for insert information
Inventor: TAKEUCHI MOTOHIKO
IPC: H04N5/91
Filed: 1985-07-18
Abstract: PURPOSE:To easily decide whether insert information is recorded or not by imposing pulse-width modulation upon a signal of specific frequency with the desired insert information to be recorded and then composing a composite video signal of a horizontal and a vertical synchronizing signal, and recording the composite video signal on a magnetic tape as the insert information. CONSTITUTION:A playback signal from a magnetic head 1 is inputted to a preamplifier 3 through a recording/playback changeover switch 2, and amplified here and inputted to a video signal processing circuit 41. The composite video signal is inputted from a synchronizing signal generating circuit 5 is inputted to an adding circuit 6, so the adding circuit 6 when inputting the output signal of a modulating circuit 11 composes the composite video signal regarding the insert information of said input signal and a composite synchronizing signal and outputs the composite video signal. The composite video signal regarding the insert information is frequency-modulated by a frequency modulating circuit 7 similarly to a video signal and inputted to the magnetic head 1 through a recording amplifier 8 and a changeover switch 2, so that the signal is recorded nearby the recording position of the vertical synchronizing signal on the magnetic tape.

Filed: 1984-07-27
Abstract: PURPOSE:To reduce the level within SiO2 film by annealing at a high temperature an oxide film on Si substrate under the ambient where hydrogen gas is included to hydrogen gas or argon gas. CONSTITUTION:A wafer forming SiO2 film on Si is placed under the argon gas ambient including hydrogen gas and is subjectd to the annealing process at 1,000 deg.C. Thereby, the levels in the SiO2 film is filled with hydrogen atom, reducing the level density. Moreover, a wafer forming SiO2 film on Si is placed under the ambient where hydrogen gas is included to the nitrogen gas and is subjected to the annealing process at 1,000 deg.C. Thereby, the levels in the SiO2 film are fillted with nitrogen atom, reducing the level density. In this case, the hydrogen causes the nitrogen atom to effectively penetrate into the SiO2 film and buries a part of levels.

     CONSTITUTION: A can shell A is inserted into a reinforcing ring 20 by the ascent of a lifter 1 and when it is pressed in the axial direction with the energizing force of a spring 14 together with a can cover B, the can shell A is press- contacted to the inside cylindrical member 21 of a reinforcing ring 20 by its slight deformation in the radial direction and rotated integrally with the inner side cylindrical member 21 by the needle bearing 23 provided between the inside and outside cylindrical members 21, 22. Therefore, it is seamed by the groove 17 of a seaming roll 3 without spoiling the rotation of the flange (a) of the can shell A and the end hook (b) of the can cover B by the reinforcing ring 20. At this time, when the restraining means is pressed by the reinforcing ring 20 and the can shell A in the axial direction together with the can cover b, the deformation in the radial direction of the can shell A is constrained, hence the buckling deformation of the can shell A can be prevented even if the can cover B is seamed to the thinned can shell A.

Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To obtain a simple and light-weight reinforcing member by providing a hollow container for protecting a support from an air drag by surrounding the support of an antenna with the container. SOLUTION: An antenna 1 is supported on a base 4 by a support pillar 2 and the antenna 1 and the support 2 is surrounded by an expandable/ contractable hollow container 3. The container 3 has its lower end fixed to the base 4 and its upper end opened.

Thus, it is not necessary to include the wind receiving load in intensity calculation to make the support 2 simple and light- weight. In addition, during installing, the container 3 is at a contracted position to facilitate the operation.  In addition, since the container 3 which is made of light-weight material and is foldable is used, wind pressure is reduced and the antenna 1 is supported by simple structure.
