Abstract: PROBLEM TO BE SOLVED: To absorb and oxidation decompose hazardous materials, such as carbon monoxide and nitrogen oxides, and to improve the ability to remove the hazardous materials as compared to the case only the photocatalyst is deposited by depositing the photocatalyst and an ordinary catalyst of a metal oxide system. SOLUTION: The deodorant catalyst element is constituted by depositing the photocatalyst particles 1 and the ordinary temp. catalyst particles 2 of the metal oxide system on a base material 4 by an inorg. binder 3. This method for prepn. consists in first putting the ordinary temp. catalyst composed of the photocatalyst and the metal oxide system into a solvent, pulverizing the flocculating photocatalyst and the ordinary temp. catalyst of the metal oxide system to primary particles with a ball mill, attriter, etc., by spending time and mixing and dispersing the primary particles into the solvent. Further, a binder is added to the soln. and the soln. prepd. by mixing the soln. While shortening the time so as not to pulverize the binder component is used a coating liquid.  The film formed by applying the coating liquid and baking the coating has an increased surface area as the particles of the photocatalysts and the ordinary temp. catalyst of the metal oxide system are small. The adsorption performance and catalyst decomposition performance are improved and since the binder component is not pulverized, the film strength is improved as well.

Title: Formation of thin film
Inventor: TSUTSUGI TOKU
IPC: C03C17/245
Filed: 1988-12-07
Abstract: PURPOSE:To form a thin film consisting of crystal grains having a prescribed grain size distribution by adjusting the surface roughness of a substrate by polishing and controlling the growth of the crystal grains. CONSTITUTION:The substrate is so polished that the surface roughness of the substrate surface having the small crystal grains is fined and the surface roughness of the substrate having the large crystal grains is roughened according to the grain size distribution of the thin film to be formed. The thin film material is then stuck to the surface of the substrate by a physical vapor deposition method. For example, an ITO material is deposited by ion plating on the inside surface of the plate 12a of a rear window defogger 10 consisting of sandwich glass composed of glass plates 12a, b, on the inside and outside surface sides to form the thin heater film 16 thereon. Only the central part A on the inside surface of the plate 12a is buffed by using abrasive powder of, for example, 0.2mu grain size to provide the surface roughness smaller than in the other part. The sheet resistance value of the thin film 16 in the part where visibility is required is lowered in this way.

Title: Flat reluctance three-phase motor
Inventor: BAN ITSUKI
IPC: H02P25/08
Filed: 1994-11-09
Abstract: PURPOSE: To obtain a flat reluctance three-phase motor in which a practical output torque is obtained even when the motor is made flat, in which a rotational speed can be increased and whose efficiency can be maintained satisfactorily by a method wherein magnetic energy which is stored in an armature coil is not returned to the side of a DC power supply but the magnetic energy is used to charge a capacitor. CONSTITUTION: Magnetic energy which is stored in an armature coil 39a is not returned to the side of a DC power supply by means of a reverse current preventive diode 49a-1, but the magnetic energy charges a capacitor 47a via diodes 21b, 21a. Thereby, an electrifying current is dropped quickly so as to prevent a countertorque from being generated. Then, transistors 20a, 20b are made to conduct by a position signal, and the armature coil 39a is electrified again. An applied voltage at this time is a voltage in which a charging voltage for the capacitor 47a is added to a power supply voltage. As a result, a current in the armature coil 39a rises quickly. Thereby, the generation of reduced torque and antitorque is eliminated, a voltage whose waveform is similar to square waves is electrified, and the output torque is increased.
