Title: Production of electrically conductive material consisting of titanium dioxide crystal
Inventor: ISHII KATSUYUKI
IPC: C30B31/00
Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To form a conductive region in the crystal by selectively and accurately doping a titanium dioxide crystal having a rutile structure with lithium atoms. SOLUTION: In this production, a diffusion-preventive film 14 for preventing lithium atoms from permeating into and through a TiO2 , crystal and from being diffused within the crystal, is formed on a prescribed region of the surface of a TiO2 crystal substrate 11 and then, the diffusion-preventive film 14 is patterned into a desired shape and thereafter, the exposed part of the surface of the crystal substrate 11 through a diffusion-preventive film hole 15 in which no part of the diffusion-preventive film 14 exists, is coated with a solvent that is used for doping and contains lithium atoms and noble metal atoms having catalytic action. Then, the resulting TiO2 crystal sample 101 is heated and maintained in an atmospheric gas contg. an oxidizing gas and a reducing gas.  Thus, lithium atoms in the solvent for doping are selectively diffused through the region of the diffusion-preventive film hole 15 into a region extending in the direction of the <001> crystallographic axis inside the crystal and a blue or blackish brown conductive region 111 is formed only in this region and the other region remains unchanged as a transparent insulating region 112.

Title: Stabilized power supply circuit
Inventor: IZUMI HIRONOBU
IPC: G05F1/56
Filed: 1991-10-17
Abstract: PURPOSE:To provide a stabilized power supply circuit without providing protection resistor or protection diode. CONSTITUTION:A current mirror circuit composed of an overheat protection circuit A and transistors Tr1 and Tr2 is connected between an input terminal V1 and a ground, and the collector of the transistor Tr2 is connected to the base of a transistor Tr for power. At normal temperature, the overheat protection circuit A does not operate. At high temperature, current Io1 flows to supply electricity to the transistors Tr1 and Tr2. At this time, VCE of the transistor Tr2 gets about 0.1V. Therefore VBE of the transistor Tr is kept at low voltage and does not operate. Thus, erroneous operation can be prevented without using the protection resistor as in a conventional circuit.
