Title: Thin film transistor
Inventor: MINAMINO YUTAKA
IPC: H01L27/12
Filed: 1988-07-25
Abstract: PURPOSE:To form the high-reliability thin film transistor(TFT) by using an SiNx film which has a specific optical band gap value. CONSTITUTION:An optical band gap of SiNx is set to >=5.35eV. The unstableness of TaOx/SiNx is caused by the generation of fixed charges by the implantation of electrons from a semiconductor layer 14 to a defective level presented in TaOx/SiNx 13. For the purpose, the band gap of the SiNx interfacing with the semiconductor layer 14 is increased to decrease the number of the electrons implanted into an insulating film exceeding the potential barrier of the semiconductor layer 14 and SiNx 13. Then the band gap of the SiNx film 13 is optimized to increase an ON current by using the thin film transistor TFT of double structure of TaOx/SiNx 13. Consequently, the TFT is obtained which has excellent switching characteristics and is stable for a long time.

Patent JP-S5883486-A (JP)
Title: Vertical synchronization information generating circuit disposition
Inventor: KURAUSU KURENERU
IPC: H04N5/06
Filed: 1982-10-23
Abstract: In magnetic video-tape equipment of the helical-scan type the vertical synchronizing information is situated at the beginning of a track near the edge of the magnetic tape. When the edge portion of the magnetic tape does not cooperate correctly with the head in the case of a faulty magnetic tape or apparatus, the vertical synchronizing information is not scanned and the resulting picture will roll in a vertical direction. However, since the beginning of a track coincides with the edges of the head-change signal, the vertical synchronizing information, in accordance with the invention, is always derived from the head-change signal, i.e. even during normal undisturbed operation, and is added to the CVBS signal, the signal scanned from the magnetic tape being blocked during this time. For this purpose the edge of the head-change signal is delayed and this delay is controlled so that normally the generation of the vertical synchronizing information from the line-pulse signals which are synchronized with the preceding track starts halfway between two such line-pulse signals or their active edges. Also when the permissible phase shift to the head change signal relative to the line-pulse signal upon each head change is taken into account the vertical synchronizing information always starts an equal number of half-line periods after the beginning of a track, thereby precluding a vertical picture jump, not even by half a line period.

Filed: 1982-10-22
Abstract: PURPOSE:To confine incident light on either breadthwise side of a light guide and to improve an quenching ratio greatly by providing a heat generation and a heat absorption part which use a Peltier effect at both breadthwise end positions of the light guide. CONSTITUTION:A thin film 21 of silver and thin films 22a and 22b of copper are vapor-deposited on an SiO2 film 5 and the thin film 21 of silver is nearly as wide as the light guide 2. The thin films 22a and 22b overlap the thin film 21 of silver. An electric power 23 is connected and a current flows through the path of the copper thin film 22a, silver thin film 21, and copper thin film 22b to cause the Peltier effect. For example, a junction part A therefore serves as the heat generation part and a junction part B serves as the heat absorption part; the junction part A becomes a high-refractive index area and the junction part B becomes a low-refractive index area to confine incident light to the light guide 2 in the side A. The current is changed in direction to switch the propagation light in the light guide 2 to the light guide 3 or 4 efficiently.
