Title: Engine valve
Inventor: MORI KAZUHIKO
IPC: F01L3/02
Filed: 1988-12-23
Abstract: PURPOSE:To reduce adhesion and initial abnormal abrasion caused by adhesion even if Cu-type alloy is used as valve seat material by forming a specified thickness of oxide film on a surface of a face part of a valve including heat- resistant steel as base material. CONSTITUTION:In an engine valve, an umbrella part 2 is integrated to a lower end of a shaft part 1, while a tapered part of the umbrella part 2 is set as a face part 3 contact to a valve seat. The face part 3 is composed by forming an oxide film 5 of 100 to 5000nm thickness on a surface of a base member 4 made of heat-resistant steel. It is therefore possible to reduce the generation of adhesion to the face part 3 and initial abnormal abrasion caused by adhesion, even if Cu-type alloy having a relatively low melting point is used as a valve seat material.

Title: Oxide superconductor and production thereof
Inventor: WADA TAKAHIRO
IPC: C04B35/00
Filed: 1990-11-28
Abstract: PURPOSE:To obtain an oxide superconductor having relatively high superconducting transition temperature by burning a specific composition containing a rare earth element, Ca, Ba, Sr, Cu and 0 in a specific state. CONSTITUTION:A composition shown by the formula is burnt under an oxygen partial pressure P(O2) of 0.001 atmospheric pressure <=P(O2)<=0.2 atmospheric pressure and then heat-treated into an oxygen deficient amount in a range shown by 0.05<=z<=(x/2+0.5) to give the objective oxide superconductor shown by the formula. In the formula, R is Tm, Yb or Li; 1<=x<=0.5; 0.1<=y<=0.4. The composition shown by the formula, for example, is prepared by blending powder of Yb2O3, BaCO3, Cub, CaCO3 and SrSO3 having >=99.9% purity so as to give the composition shown by the formula. The oxide superconductor has >=50K superconducting transition temperature Tc. When silver sheath wire or thin films are produced, since a long-time heat treatment process in an oxygen- containing atmosphere, a final process, is not required, superconducting wire materials and thin films are relatively readily manufactured.

Title: Thin film transistor and its manufacture
Inventor: MISHIMA YASUYOSHI
IPC: G02F1/136
Filed: 1990-11-28
Abstract: PURPOSE:To prevent leakage current from occurring upon OFF time by a forming a gradient of impurity concentration in a junction between the main and side faces of a contact layer and an operation semiconductor layer. CONSTITUTION:A gradient of impurity concentration is formed in a junction between the main and side faces of contact layers 16, 17 of a thin film transistor 10 and an operating semiconductor layer 15. The gradient of impurity concentration is formed by a pile up treatment of an operating semiconductor layer 15 after coating with the contact layers 16,17 with impurities different from doping ones of the contact layers 16,17, where doping impurities of the contact layers 16,17 are so selected as to be concentrated higher than coating impurities and to be smaller in diffusion coefficient in silicon. This process prevents field concentration upon OFF time of a thin film transistor operation and excludes interferences such as increases in leakage current.
