The present invention provides a novel method for producing fine particles of aripiprazole anhydride crystals B. The method for producing fine particles of aripiprazole anhydride crystals B comprises the steps of: (1) heating and dissolving crude aripiprazole in a lower alcohol, and subsequently cooling the resulting mixture to precipitate crystals to obtain crystals of aripiprazole lower alcohol solvate; (2) subjecting the crystals of aripiprazole lower alcohol solvate to wet-milling in the form of a slurry containing the lower alcohol; and (3) subjecting the dispersion of the wet-milled crystals to solid-liquid separation to obtain the crystals, and heating the crystals.

Provided is a device for preventing information leakage including: a storage unit that stores message time, request source information, and request destination information in relation to each information requesting message; a unit that suspends a response message containing personal information in response messages in response to the information requesting messages, for a predetermined suspended time from a message time of the corresponding information requesting message; a unit that counts the number of information requesting messages transmitted from the same request source to the same destination and corresponding to the suspended response message on the basis of information stored in the storage unit; and a unit that, in the case where the counted number of the information requesting messages exceeds a predetermined threshold value, applies a protection process to the suspended response message so that the personal information contained in the suspended response message is not received by the request source.

If there is static friction, the magnetic pole position estimation is completed at the time when error torque used for magnetic pole position estimation becomes less than the friction, so that there remains magnetic pole error. A problem has been that when the error torque becomes less than a forward static friction, there remains a positive magnetic pole deviation and when the error torque becomes less than a backward static friction, there remains a negative magnetic pole deviation. By shifting in the negative direction and the positive direction initial values for estimating a magnetic pole error in operation sets, a true pole-error estimation value is estimated in the use of a pole-error estimation value having a positive magnetic pole error obtained by the positive shift operation and a negative one obtained by the negative shift operation, which can reduce estimation error due to the static friction.

A method for fabricating a chalcopyrite-type thin film solar cell includes a first step of forming onto a Mo electrode layer 2 a precursor including an In metal layer and a Cu—Ga alloy layer by sputtering, a second step of attaching an alkali-metal solution onto the precursor, a selenization step of subjecting the substrate 1 which has undergone both the first and the second steps to a selenization treatment, and a transparent electrode forming step of depositing an optically transparent conductive layer. As the alkali-metal solution, an aqueous solution of an alkali metal compound, such as sodium tetraborate, sodium sulfide, and sodium aluminum sulfate, can be used.

A method of producing a light absorbing layer of CIGS for a solar cell by forming a precursor film on a back electrode and treating the precursor film in a selenium atmosphere, wherein an alkali layer is formed on the back electrode by dipping the back electrode in an aqueous solution containing alkali metals and drying and then a laminated precursor is formed on the alkali layer. By applying this method, the alkali layer whose components of Ia-group elements are diffused into the light absorbing layer to improve power conversion efficiency thereof can be easily formed with no fear of denaturing the back electrode and peeling of the layer at the boundary between the light absorbing layer and the back electrode.

An optical transmission system accomplishes optical transmission to a long distance by combining a multiplexing line terminal with optical amplifiers, linear repeaters, and regenerators with optical amplifiers combined together. The system also accomplishes the optical transmission to a short distance by directly connecting the linear terminals therebetween, with an electric-to-optic converter replaced by an electric-to-optic converter having a semiconductor amplifier, with an optic-to-electric converter by an optic-to-electric converter having an avalanche photodiode as light receiver, an with no use of any optical booster amplifier and optical preamplifier in the multiplexing line terminal. With these, the optical transmission system can be easily constructed depending on the transmission distance required.
