摘要:
A main body (10) of a percutaneous administration device is formed from a resilient biodegradable resin, such as an elastomer resin or a silicone rubber, and includes a substrate (12) and multiple micropiles (14) formed on the substrate. The leading ends of each micropile (14) is shaped with a flat contact face (14A) that stops upon the contact with the skin and does not perforate the skin. Depressed portions (18) are formed in the contact face (14A). The depressed portions hold a functional substance (16) having a whitening effect, such as powdered or liquid vitamin C or provitamin C, or fine ceramic particles impregnated with vitamin C.

The method of the present invention can 1) produce spherical and scaly ultrafine particles without pulverization, 2) obtain spherical ultrafine particles having a sharp spherical particle diameter distribution without requiring a sieving step, 3) produce spherical ultrafine particles extremely approximating a true circle and possessing a particle diameter of 100 nm˜50,000 nm allowing selection of a size suitable for the particular purpose of use and 4) produce spherical ultrafine particles on a commercial scale at low cost. There is also provided spherical ultrafine particles produced by the above production process. The spherical ultrafine particles of the present invention are characterized by a form having circularity of 0.9 to 1.0 and a particle diameter of 0.01 μm to 10 μm without pulverization. The spherical ultrafine particles can be produced by the method of the present invention using as a nozzle a base having special through holes and hole density. In this base nozzle, the through holes have a diameter of 0.05 μm˜50 μm, a through hole aspect ratio of 5 to 200 and a hole density of 100 to 7,000/cm2.

A toner manufacturing method, a toner manufacturing apparatus, and a toner are disclosed. The toner manufacturing apparatus includes a droplet generating unit that includes a thin film in which plural nozzles are formed, and an annular vibrating unit that is arranged at a perimeter of a deformable domain of the thin film for vibrating the thin film; a storage unit for storing a toner-containing liquid that includes at least a resin and a colorant, and for supplying the toner-containing liquid 10 to the droplet generating unit; and a granulating unit for solidifying droplets that are periodically breathed out from the nozzles of the droplet generating unit to form toner particles.
摘要:
To provide a probe card that is used when carrying out electrical inspection of a high-density fine circuit board to be measured.A probe card has plural probe pins, an insulator having plural through-holes through which the probe pins pass, and a pair of substrates that are positioned at both sides of the insulator and that have supporting holes into which end portions of the probe pins are inserted respectively. The pair of substrates and the insulator are provided so as to be slidable. One substrate is formed of a material having a same value as or an approximate value of a coefficient of thermal expansion of a fine circuit board to be measured, and another substrate is formed of a material having a same value as or an approximate value of a coefficient of thermal expansion of a wiring board for signal input/output.By doing so, even if the fine circuit board to be measured and the wiring board for signal input/output thermally expand, the probe pins can always be made to contact the respective electrodes of the fine circuit board to be measured and the wiring board for signal input/output, and the probe pins that are adjacent do not short circuit. Therefore, electrical inspection of a high-density fine circuit board to be measured can be carried out at one time, and furthermore, precisely.
