Title: Video signal recording method
Inventor: MAKISHIMA SUGIO
IPC: H04N5/782
Filed: 1989-09-22
Abstract: PURPOSE:To secure the larger information volume of luminance signals while keeping compatibility with a conventional method by dividing a video track into two and recording the same video signal as conventional on one divided track and changing the azimuth angle to record a video signal, which includes a luminance signal supplementing the luminance signal, on the other. CONSTITUTION:Standard A and standard B video tracks are divided to video tracks A and A' and video tracks B and B' respectively. A and B heads 13 and 15 have the same azimuth angles as a normal A head 11 and a normal B head 12, and A' and B' heads 14 and 16 have different azimuth angles. Video signals of the same kind as video signals recorded by normal A and normal B heads 11 and 12 are recorded on A and B video tracks by A and B heads 13 and 15, and video signals including luminance signal which supplement the luminance signals included in recorded video signals are recorded on A' and B' video tracks by A' and B' heads 14 and 16. Thus, the compatibility with a conventional VTR device is kept and the larger information volume of luminance signals is recorded.

Title: Optical system for wavelength multiplex modulation
Inventor: KANAYAMA KOICHI
IPC: H04B10/00
Filed: 1985-11-05
Abstract: PURPOSE:To simplify a system by using an ultrasonic deflecting element using the acoustooptic effect to make it possible that signals independent of each other are put on rays different in wavelength directly without converting optical signals to electric signals in case of wavelength multiplex communication. CONSTITUTION:A wavelength multiplex light having wavelengths lambda1 and lambda2 propagated in the first transmission optical fiber 1 is radiated from the end face of the optical fiber 1 and is converged by a converging lens 2 and is made incident on an ultrasonic optical deflecting element. Oscillation levels of oscillators 5 and 6 are modulated independently and are applied to an ultrasonic transducer 4 of the ultrasonic optical deflecting element and an ultrasonic wave bundle 14 is propagated in an acoustooptic medium, and a diffracted light 11 is generated by the acoustooptic effect. At this time, optical wavelengths lambda1 and lambda2 and ultrasonic frequencies f1 and f2 satisfy relations lambda1f1=lambda2f2. Consequently, the diffracted light 11 has two wavelengths lambda1 and lambda2 modulated by signals inputted from modulating signal input terminals 7 and 8. Thus, the transmitted two-wavelength multiplex light having wavelengths lambda1 and lambda2 is modulated newly independently.

IPC: H01L27/10
Filed: 1991-09-27
Abstract: PURPOSE:To prevent impurities from permeating into a dielectric film of a gate, and reduce the width of an SGT cell as far as a bit line can be connected, by forming a ring type trench on the peripheral surface of a columnar protrusion composed of semiconductor, and forming a gate electrode in the ring type trench via the dielectric film. CONSTITUTION:A ring type trench 8 is formed on the peripheral surface of a columnar protrusion 2 composed of semiconductor, and a gate electrode 15 is formed in the ring type trench 8 via a dielectric film 8. The gate electrode 15 is formed in the ring type trench 8 via an Si3N4 film/silicon film 13. When ions are implanted for forming a source region 20, impurities do not permeate into the Si3N4/silicon film 13 of the gate insulating film. Since the gate electrode 15 is buried in the columnar protrusion 2, the width of an SGT cell is reduced by that amount, and the top part of said cell has a size wherein a bit line can be connected.

Abstract: PURPOSE:To provide a resin sealed type semiconductor device with a heat sink which can reduce the stress to the a sealing resin section although the heat radiating property of the semiconductor device can be improved. CONSTITUTION:A sealing resin section 1 not only seals and protects an electronic circuit containing a semiconductor element 2, but also fixes a lead terminal 40.
