Title: Production of single crystal thin film by liquid-phase epitaxy
Inventor: TSUJI MASAHIRO
IPC: C30B29/16
Filed: 1992-12-17
Abstract: PURPOSE:To prevent the generation of microcracks in the growth of a single crystal thin film by a liquid-phase epitaxy method using plural materials for forming the single crystal thin film by independently heating and calcining each material before mixing. CONSTITUTION:Plural materials (e.g. lithium carbonate and niobium oxide) necessary for the production of a single crystal thin film (e.g. lithium niobate single crystal thin film) by liquid-phase epitaxy method are prepared beforehand. Each material is separately heated and calcined before mixing. The calcination is carried out at a temperature above the heat-decomposition temperature of the crystal, water of crystallization contained in each material and below the melting point of each material. The calcined materials are mixed with each other, heated to obtain a molten mixture, a single crystal substrate is made to contact with the molten mixture and a single crystal thin film is grown by liquid-phase epitaxial growth. Since the water of crystallization is removed by calcining each material, the generation of bubbles in the crystal growing can be suppressed to prevent the adhesion of bubbles to the surface of the thin film.

Title: Circuit and method for protecting overcurrent
Inventor: JOSA TAKASHI
IPC: H02H3/08
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To provide an overcurrent protecting circuit which, when an overcurrent is caused to flow in a circuit, detects the overcurrent without fail and stop further supplying the power to the load side, even if the load is a semiconductor circuit or the like. SOLUTION: If a high current is caused to flow in an IC 112, the current flows as it is into a resistor 113 and pulsating voltage fluctuations occur across the terminals of the resistor 113, which maintains an 'on' state for comparatively long time in a pulse extending circuit 108. Consequently, a FET 105 is turned on for comparatively long time, and the terminals between drain and source are put into an almost short-circuited state. A high current caused to flow in this state melts a fuse 101. As a result, a central processing circuit 110, is able to secure conducting time long enough for melting the fuse 101, and is able to melt down the fuse without fail, if an abnormal state occurs.
