摘要:
A method for manufacturing a microparticulate anatase or rutile titanium oxide dispersion from a peroxotitanic acid solution optionally containing tin, wherein the method for manufacturing an anatase or rutile titanium oxide dispersion is characterized in that the peroxotitanic acid solution is fed continuously to a flow reactor and subjected to hydrothermal treatment at 150 to 250° C. and 0.5 to 10 MPa. The invention makes it possible to provide a method for manufacturing a microparticulate anatase or rutile titanium oxide dispersion having excellent stability in regard to the titanium oxide microparticles and enabling a high-transparency photocatalytic thin film to be produced, and to provide a member having a photocatalytic thin film formed on the surface using this dispersion.

A functional optical device has cores which are trenches, different portions of the cores being formed from different core materials. The optical device can be formed by forming trenches 5,7,9 within a substrate (normally a substrate 1 covered by a cladding layer 3), covering at least part of at least one trench 7 with a cover 11, depositing a first cladding material to fill the trenches 5,9 which are not covered, removing the cover 11, depositing a second cladding layer 15 of a second cladding material to fill the trenches 7 which were previously covered, removing core material outside the trenches 5,7,9 and applying a cladding layer to cover the trenches.

A fluid pressure regulating apparatus comprises a body having a fluid passage to be connected to a machine driven by a pressurized fluid and to a pressurized fluid supplying source. The rotation of a ring member on the outer surface of the body, around the longitudinal center line thereof, responsively moves a regulating member inside the body, so as to vary selectively the pressing force, applied by the regulating member to an urging member sandwiched between the regulating member and an actuator member when the actuator member is moved from a first position to a second position inside the body by an increased urging force of the urging member, a valve body is driven by the actuator member and moved from a closed position to an open position. The valve body is maintained in its open position by the actuator member, to which the increased urging force is applied, against the pressure of the fluid in the passage. When the actuator member is in its first position (i.e., without an increased urging force being applied thereto), the valve body is allowed to move toward its open position. Thus, the urging force responsively arising from the rotation of the ring causes movement of the valve body, which movement thereby regulates the pressure of the fluid supplied to the machine.
摘要:
Electromagnetic reciprocating pump including a plurality of pumps combined in such a manner that the mode of connection between the suction inlet and the discharge outlet in each of the pumps is allowed to be changed and, as the result, the amount of suction or discharge or the degree of vacuum or compression is allowed to be selected at a multiplicity of stages without any loss of the energy of the alternating current power. The plurality of pumps are disposed in such a manner that the axes of their respective pistons intersect one another at one point and the pumps themselves are rotationally symmetrical with respect to the point mentioned above.

An optical waveguide apparatus comprises a substrate (1), a patterned waveguide as a core (4), and an upper cladding layer (10) formed on the substrate. The core is surrounded by a cladding comprising the substrate as a lower cladding layer and the upper cladding layer and smaller in refractive index than the core. The core and the cladding are integrally coupled to each other in a manner such that temperature-dependent expansion or contraction is performed substantially in accordance the characteristic of the cladding. The core and the cladding are made of materials selected so that the variation in optical path length according to the temperature-dependent expansion or contraction of the cladding is canceled by the variation in optical path length according to temperature-dependent variation in refractive index of the core.

A pneumatic structure a part or the whole of which can desirably be put in motion when the pneumatic structure is shaped into, for example, outlines of living things or the like. A spare portion having at least a pair of bending fulcra is formed on the structure main body on the opposite side to a bending direction of the structure, and a length of arc between the respective fulcra of the spare portion is made shorter than 1/2 outer circumferential length of the pneumatic structure containing a set of the respective fulcra, whereby the structure can positively be maintained in a desired state under normal conditions and bending operation thereof can be promptly effected at a large angle by means of small external force.
摘要:
An instrument for recovering the functions of the carpal joint, the hand and the fingers including a ballonet operatively connected to an air supply for subjecting the ballonet to repeated expansion and contraction by feeding and discharging compressed air thereto. Finger-engaging members being provided on the outer surface of the ballonet. Fastening members being provided on the outer surface of the ballonet for fixation of the carpal joint region and the region adjacent thereto. An individual's hand positioned within the finger-engaging members and the fastening members is extended and fanned as the ballonet is inflated and contracted as the ballonet is deflated.
摘要:
A process and apparatus for drying or heating a particulate material by means of heat transfer media which is brought into direct contact with the particulate material within a continuously rotating cylindrical drum. The particulate material flows in one general overall direction through the drum and the heat transfer media flows in a generally opposite direction through the drum. The particulate material is subjected to heat treatment by repeatedly coming into direct and immediate physical contact with the heat transfer media in the course of flowing through the drum while it is subsequently separated from the heat transfer media per revolution of the drum.
