Abstract: PROBLEM TO BE SOLVED: To provide a photocatalyst body which has a higher photocatalytic action than that of conventional ones. SOLUTION: In order to improve the photocatalytic ability of the photocatalyst body, this photocatalyst body has a structure where a photocatalyst is carried in pores formed in a transparent base material so as to be oriented in a prescribed direction and fluid to be treated passes through the pores. By having the structure where the fluid to be treated passes through the pores carrying photocatalytic fine particles, the oxidation and decomposition reaction of adsorbed components to be treated proceeds also in the pores. As the photocatalyst body has the structure where the fluid to be treated passes through the pores sequentially, the desorption of intermediate reactants in the middle of the oxidation and decomposition reaction can be inhibited, so that the reaction can proceed more completely.

Abstract: PROBLEM TO BE SOLVED: To provide a short on-glass antenna, by which an occupied area on a glass pane can be decreased. SOLUTION: This on-glass antenna has a glass pane 1, an antenna conductor 2 and a high dielectric 3 for integrally bonding this antenna conductor 2 to the glass pane 1. This high dielectric 3 is composed of a glass component and a dielectric component. When a radio wave passes the high dielectric, the wavelength thereof is shortened. Such a shortened radio wave is received by the antenna conductor 2. Therefore, the antenna conductor 2 can be shortened in comparison with the case of using no high dielectric 3.

Abstract: PROBLEM TO BE SOLVED: To provide a desulfurizer for efficiently removing, prior to combustion, aromatic sulfur-containing compounds in an engine fuel. SOLUTION: This desulfurizer e.g. for mounting on a vehicle, which is installed between a fuel tank and the injector of an engine, utilizes a combination of a sulfur-containing compound adsorbent for adsorbing and concentrating sulfur-containing compounds and a sulfur-containing compound oxidizing agent or oxidizing catalyst for oxidizing the thus adsorbed sulfur-containing compounds and also has a means for collecting/removing sulfur-containing oxides formed. With this desulfurizer, the particulate matter in exhaust gas can be halved and the durability of a catalyst for NOx removal can be about doubly raised.

Abstract: PROBLEM TO BE SOLVED: To provide an inorganic-organic hybrid excellent in lipophilicity and a synthetic method of the same, while the above lipophilic hybrid could not be obtained in conventional inorganic-organic hybrid because wettability to lubricating oil could not be controlled although the hybrid was excellent in flexibility and heat resistance. SOLUTION: The improvement of the lipophilicity of the inorganic-organic hybrid has been achieved by including an aromatic group as an organic group and making the above inorganic-organic hybrid porous. That is, in the inorganic- organic hybrid synthesized by hydrolysis and condensation of an organoalkoxysilane or organoalkoxysilane and metal alkoxide, the lipophilic inorganic-organic hybrid is obtained by including 5 or more mol% of aromatic groups as the constituent organic group wherein the above organic groups are 0.1 or more molar times and 3 or less molar times to total of silicon and metal atoms.

Abstract: PROBLEM TO BE SOLVED: To provide the subject device capable of reducing the contents of polycyclic aromatic compounds in a fuel and not requiring a treatment for regenerating a porous material by carrying a catalyst for decomposing the polycyclic aromatic components on the adsorbing surfaces of the porous material having a specific average pore diameter or on places near to the adsorbing surfaces. SOLUTION: A catalyst for decomposing polycyclic aromatic compounds is carried on the adsorbing surfaces of a porous material having the adsorbing surfaces and having an average pore diameter of 0.5-100 nm or on places near to the adsorbing surfaces. A fuel-modifying device 10 filled with the grains of the porous material carrying the catalyst is disposed between a fuel-supplying system 20 and a combustion system 30, and the retention of a fuel in the fuel- modifying device 10 for 20 min or longer enables to substantially perfectly remove the polycyclic aromatic compounds. When a photo-catalyst is used as the catalyst and irradiated with UV light, substances adsorbed on the catalyst are released from the adsorbing surfaces, thereby enabling to prevent the deterioration in the degree for removing the polycyclic aromatic compounds.

The resultant compact is fired at a temp. corresponding to 92-97% of the densification temp. of the ceramic material to produce the objective porous ceramic film having 5-15% porosity. In this film, >=80% of the pores are in the range of 50-90nm pore diameter.

Abstract: PROBLEM TO BE SOLVED: To obtain a unidirectional or bidirectional rotational driving gear that delivers a large rotational angle, by securing one side of a driving body on an object other than mobile units, and joining a vibrator to the other end so that the width of the driving body will be almost the same as, or slightly smaller than, that of grooves. SOLUTION: Grooves 5 are formed on the rotary shaft 1 of a driving gear, and the grooves 5 are in contact with the side portions 6a, 6b of vibrators 2, 2'. The ends of the vibrators 2, 2' on one side are fixed at fixed portions 4 by means of fixtures. There are vibrators 2, 2' and vibrator elements 3, 3' on both sides of one fixed portion. For driving, oscillating force is applied to the vibrator element 3 (or 3') on one side of the fixed portion 4. If forward rotation is caused when the force is applied to the vibrator element 3, it follows that backward rotation is caused when the force is applied to the vibrator element 3'. In order to transmit oscillation of the oscillators 2, 2', they are joined to the vibrator elements 3, 3' at their surfaces. When the vibrators are expanded due to the oscillation of the elements 3, 3', frictional force is larger at the side portion 6a than at the side portion 6b. This is also the case when the vibrators are shrunken. This obtains a driving gear wherein the rotary shaft is rotated in the two directions and a large rotational angle is obtained.

Abstract: PURPOSE:To make the piezoelectric characteristic and strength of the products uniform by uniformly mixing and controlling the lead atmosphere and oxygen atmosphere around a piezoelectric ceramic compact. CONSTITUTION:A piezoelectric ceramic compact is sintered in a lead atmosphere and in an oxygen atmosphere to produce a piezoelectric ceramic. A lead oxide is contained in the compact and decomposed in sintering to liberate oxygen. Since the lead oxide is contained in the compact, oxygen is liberated from the inside and surface of the compact in sintering, and the oxygen atmosphere is uniformly mixed with the lead atmosphere around the compact. Consequently, the sintered compact is densified, and the piezoelectric characteristic and strength of the products are surely improved and made uniform.
