Abstract: A method for forming a titanium oxide film that can be formed on a surface of a base material without a heating step. In Step 0, a surface of a molded product (base material) composed of a cyclic olefin-based resin is irradiated with ultraviolet light in an air atmosphere. In Step 1, the base material is immersed in a mixed liquid of an aqueous solution of titanium chloride and a nitrite ion-containing aqueous solution. A titanium oxide film grows by repeating oxidation of a titanium ion. In Step 2, the base material is pulled out from the mixed liquid, and then washed to stop the reaction. The film thickness can be controlled by controlling this immersion time. In Step 3, the base material after washing is dried at room temperature.

Abstract: In order to carry out various analyses at high accuracy in a site where analysis is needed using a disposable microchip, the microchip is disposed on a display of a tablet terminal device, and a sample or specimen is dropped into a flow path of the microchip to trigger a reaction of the sample in the microchip. Light emitted from the display of the tablet terminal device is applied to the microchip, and the reaction caused by the applied light in the microchip is measured. When an induced fluorescence method using the applied light is adopted as a measuring method, fluorescence that corresponds to the reaction is observed, and detected by, for example, a built-in camera of the tablet terminal device. The detection signal is analyzed by an arithmetic unit of the tablet terminal device.

The free end of the fluid releasing unit is shaped like an injection needle, and the aperture serves as a fluid release opening. The free end of the fluid recovering unit is shaped like an injection needle, and the aperture serves as a fluid recovery opening.

After being laminated, the laminated workpieces are conveyed to a workpiece heating mechanism and heated to increase the workpiece temperature to a predetermined temperature, and this temperature is maintained until joining is completed. The laminated workpieces are brought into a thermally expanded state upon heating, and are joined in this state.

Abstract: In a method for forming a titanium oxide film, with which a titanium oxide film can be formed on a surface of a glass base material, a surface of a molded product composed of a glass is irradiated with ultraviolet light in an air atmosphere in step 0. In Step 1, the base material is immersed in a mixed liquid of an aqueous solution of titanium chloride and a nitrite ion-containing aqueous solution. As a result of the immersion, a titanium oxide film is grown by repeating oxidation of a titanium ion, binding of the oxidized titanium ion to oxygen, and binding of the bound oxygen to a titanium ion at the cleaved end of the glass molded product. In Step 2, the base material is pulled out from the mixed liquid, and then washed to stop the reaction. The film thickness can be controlled by controlling the immersion time.

Next, the molded is immersed in a tank filled, for example, with a fluorine compound solution, and a SAM film that is a self-assembled monolayer is formed on the surface activated by ultraviolet radiation.
