Title: Heat sink with integrated fin and production thereof
Inventor: YAMAMOTO TAKESHI
IPC: H01L23/373
Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To provide a heat sink with integrated fins having high fin strength, superior in heat dissipation properties and requiring no bonding between the heat sink and the fins. SOLUTION: Fins 11 are integrally formed of the same metal-based composite material as a heat sink 1 therewith, thus obtaining a hat sink 1 integrated with fins 11 in strength and heat dissipation properties. Since the fin 11 has a complicated shape, the heat sink 1 cannot be formed simply of a steel case normally used for casting. A molding case made of sodium chloride is thereby employed as a die at a part for forming the fin 11. The heat sink 1 is taken out from the steel case along with the molding case after casting, and then the molding case is removed using a solvent, e.g., water. According to the method, a heat sink 1 integrated with fins 11 can be produced easily because of high solubility and decayable property of sodium chloride.

Title: Hot water supply apparatus with bath boiler
Inventor: ISHIHARA TOSHIAKI
IPC: F24H1/10
Filed: 1988-11-16
Abstract: PURPOSE:To produce air bubbles in the vicinity of an outlet in order to prevent eddy currents and noise from being produced by a method wherein the hot water supplied from an inlet is received at a position apart from the inlet, and spouted towards the outlet through a flow path. CONSTITUTION:In a sictern 11, a water path 16 is provided, hot water is supplied into a receiving funnel 15, and spouted from a discharge port 18 towards the vicinity of an outlet 13. As the hot water is directly discharged into water in case the water level in the sictank 11 is higher than the elevation of the discharge port 18, air bubbles are not produced. As a result, a pump 21 works at the maximum capacity to reduce the water level in the sictern as the hot water does not contain air bubbles. On the contrary, in case the water level in the sictank is lower than the elevation of the discharge port 18, the hot water discharged from the discharge port 18 is spouted in the water through air so that the hot water pushes air into the water and fine air bubbles are produced in the water. Thereby, eddy currents and accompanying noise is prevented from being produced in the vicinity of the outlet 13. As the hot water contains air bubbles, the capacity of the pump 21 is reduced and the water level in the sictern 11 rises.

Title: Production of titania film
Inventor: NOMURA YUKIO
IPC: B01J35/02
Filed: 1997-10-22
Abstract: PROBLEM TO BE SOLVED: To obtain a titania film having excellent adhesion property and high photocatalytic activity at a rather low drying or calcining temp. by applying a soln. containing a titanium compd. and nonwater solvent on a substrate surface in an anhydrous atmosphere, drying or calcining the coating film at normal temp. in a water-contg. atmosphere. SOLUTION: A soln. containing a nonwater solvent and a titanium compd. having hydrocarbon groups or alkoxy groups is applied on the surface of a base body in an anhydrous atmosphere of <=35% humidity. Then the base body is dried or calcined at normal temp. in a water-contg. atmosphere to form a titania film. Thereby, the formation of oligomers by polymn. of the titanium compd. is suppressed as well as the reaction of the water content in air and the titanium compd. is suppressed. Thus, the reaction efficiency of the titanium compd. with the surface of the base body is increased to suppress the formation of oligomers of the titanium compd. Since the titanium compd. can be uniformly dispersed in the solvent, the obtd. titania film has high uniformity.

Title: Device for estimating state
Inventor: MAKIMOTO NOBUO
IPC: G01S5/18
Filed: 1996-10-31
Abstract: PROBLEM TO BE SOLVED: To make stable dynamic characteristic judgment, and to make it difficult to generate time delay by outputting the adaptability of a dynamic characteristic model from the difference of each state estimating part and the covariance. SOLUTION: A common observed value is inputted to a state estimating part 101 whose follow-up ability is unsatisfactory and a state estimating part 102 whose follow-up ability is satisfactory, and the state of this system is estimated. Each state estimating part 101 and 102 outputs a state estimated value and a state estimated value error covariance. An estimated value analyzing part 103 calculates the difference of each state estimating part output, and calculates the covariance of the difference. Then, the estimated value analyzing part 103 outputs the adaptability of a dynamic characteristic model from the difference of each state estimating part output and the covariance. When the supposed dynamic characteristic model is correct, the two estimated results have large correlation and a difference is hardly generated since the common observed value is inputted.  On the other hand, when the dynamic characteristic model is incorrect, a difference is generated between the two estimated results due to the difference of the follow-up ability. Therefore, the adaptability of the dynamic characteristic model can be judged by evaluating the balance of the correlation and the difference.
