Title: Video tape recorder
Inventor: SUDO KAZUO
IPC: G11B5/588
Filed: 1986-10-29
Abstract: PURPOSE:To form a recording track at a pitch high accuracy on a tape by connecting the first and the second magnetic heads to recording and reproducing amplifying circuits, respectively, giving a control signal to each of them, and switching an operation mode of the circuit from recording to reproduction at every head. CONSTITUTION:Circuits 11, 12 have recording 13, 14 and reproducing 15, 16 amplifying circuits, respectively, controlled by signals SCA, SCB synchronized with a pulse SWP, heads CH1, CH2 record a signal Sf5 to a servo-area ARS of a prescribed track, and thereafter, while its adjacent ARS is scanned, 'H' is kept. During this period only, the circuits 11, 12 are switched from a recording mode to a reproducing mode, and crosstalks SOSA, SOSB of a pilot signal SfS are obtained through the head. They are selected 21, 22 by the pulse SWP, and when a video area ARV is being scanned, a video signal SOV is obtained, and when an audio area ARA and a servo-area ARS are being scanned, said signal is separated into a crosstalk signal SOS and a PCM audio signal SOPCM. When SOS is brought to sampling, and the head is controlled so as to become a peak value VrefA=VrefB, recording can be executed onto a tape at a prescribed track pitch with high accuracy.

Title: Electromagnetic wave absorber
Inventor: SHIMIZU KATSUAKI
IPC: H05K9/00
Filed: 1988-10-14
Abstract: PURPOSE:To make it possible to handle conveniently an electromagnetic wave absorber in a light weight by a method wherein a form retentive sheet having a conductive film is held and fixed between the two sides not adjoining each other of a rectangular cylinder of a quadrangle-shaped section. CONSTITUTION:For example, a rectangular form retentive sheet 2 having a conductive film is housed in a rectangular cylinder 11 of a quadrangular section. The opposed two sides of the sheet 2 respectively come into contact to the two sides not adjoining each other of the cylinder 1 and the sheet 2 is fixed so that it is not moved by the form shelf stability of the sheet 2 itself. The cylinder 11 and the sheet 2 are separated from each other at the time of transfer and the cylinder 11 is flatly crushed and is transferred. At the time of use, one end part of the cylinder 11 becomes the side of incidence of an electromagnetic wave and the longitudinal direction of the cylinder 11 becomes the traveling direction of the electromagnetic wave. Therefore, it is desirable that the surface resistivity of the cylinder 11 is continuously changed from the one end part of the cylinder 11 toward the end part on the side of reflection the electromagnetic wave. Thereby, an electromagnetic wave absorber can be handled conveniently in a light weight.

Title: Sputter growth method of electrode used in ferroelectric capacitor
Inventor: INOUE HISAYA
IPC: C23C14/08
Filed: 1998-09-16
Abstract: PROBLEM TO BE SOLVED: To continuously and simply form a film at a temperature keeping excellent capacitance characteristic, by changing only DC input power without changing sputter gas composition containing oxygen. SOLUTION: When a conductive laminated film constituted of metal used as electrodes 12, 15 of a ferroelectric capacitor 1 and a metal oxide film is grown by sputter growth, bias applying between targets is made by a DC system, and only the DC input power is changed without changing conditions such as sputter gas composition, oxygen partial pressure and film forming temperature. As a result, composition of the conductive laminated film, i.e., the state of oxidation can be controlled at a comparatively low temperature. By controlling the oxygen partial pressure during sputter film formation, crystal orientation of metal oxide to be formed in a film can be controlled. By simultaneously controlling a film forming temperature during sputter film formation, crystal orientation of the metal oxide to be formed in a film can be controlled.
