Polyvalent metal salts of 2-mercaptopyridine-N-oxide which are made into fine powder in which particles having a size below 0.2 micron are contained in amounts not smaller than 50 wt %.Preparing process of the above and antibacterial compositions comprising the above are also disclosed.When the finely powdered polyvalent metal salts of 2-mercaptopyridine-N-oxide are incorporated into shampoo or rinse compositions, dispersion stability of the salts is remarkably improved with the enhanced adsorbability of the particles on the skin and hair, thus antibacterial and dandruff-removing actions owing to the salts are further improved.
摘要:
In an abnormal shadow detecting system, a characteristic value on the shape and/or the density of a prospective area of a micro calcification shadow set in an image of an object is extracted on the basis of image data representing the image of the object, and whether a micro calcification shadow really exists in the prospective area is determined on the basis of the calculated characteristic value.
摘要:
Processing for detecting an abnormal pattern candidate embedded in a medical image having been obtained from an image recording operation is performed on an image signal representing the medical image. In cases where the image signal is one which has been subjected to predetermined signal processing, correction processing is performed on the image signal such that the abnormal pattern candidate detecting processing performed on the image signal, which has been subjected to the predetermined signal processing, does not depend upon the predetermined signal processing. The abnormal pattern candidate detecting processing is then performed on the image signal, which has been obtained from the correction processing.

A lens-fitted photo film unit is pre-loaded with photo film, and is a flash built-in type. A booster circuit boosts power source voltage to obtain high voltage. A main capacitor stores charge at the high voltage. A flash discharge tube is connected with the main capacitor, and emits flash light by discharge at the high voltage. A trigger circuit triggers the discharge of the flash discharge tube in response to an exposing operation. A main circuit board has the booster circuit and the trigger circuit mounted thereon. A subsidiary circuit board is connected with the main circuit board, and has a flash quenching circuit mounted thereon. The flash quenching circuit operates in an auxiliary manner, and automatically adjusts the amount of the flash light.

A lens-fitted photo film unit has an electronic flash device (11, 30; 115) with a printed circuit board (173). The flash device includes a flash-emitting section (6, 170) for emitting flash light toward a photographic field, and a main capacitor (31, 155) for storing charge to be discharged in the flash-emitting section. The printed circuit board converts a current of a battery (12, 127) into a current of high voltage to be supplied to the main capacitor. An LED is driven to emit light in response to charging of the main capacitor at a predetermined level. The flash-emitting section is arranged to be slidably disposed on said printed circuit board.

A total photo-lab system for automatic printing processing, cutting, sorting and enveloping. Each of a plurality of films spliced into a film roll is provided with a label printed with a respective ID number bar code. The same ID number bar code is provided on a respective envelope. During printing, the ID number of each film set in a printing position is read out so as to record a punch code indicative of the same ID number on a photographic paper besides the first print frame made from that film. The printed film is reserved until the corresponding print frames have been processed. The ID number of the processed photographic paper is read and compared with the ID number of the reserved film. When these ID numbers are identical, the film is cut and inserted into a film sheath sheet, whereas the photographic paper is cut into individual prints, and are sorted into each set of prints belonging to the same film. The film sheath sheet is inserted into the envelope having the same ID number as the film contained in that film sheath sheet, and then the prints having the same ID number are inserted therein.
摘要:
A novel monophosphate and a novel diphosphate prepared by a phosphatidyl transfer reaction of a phospholipid and an alcohol in the presence of phospholipase D are disclosed. The phosphates can independently or together form small and stable liposomes which can include active components therein. Cosmetic compositions comprising these phosphates or liposomes penetrate well into the hair and the skin, and exhibit long-lasting excellent moisture-retaining, beauty, skin-activation effects.

摘要:
A novel method for purifying a sugar phosphate or its salt, in which a sugar-containing mixture of a sugar phosphate or its salt and phosphoric acid or its salt is subjected to electrodialysis to remove the phosphoric acid or its salt from the mixture.According to this method, the phosphoric acid or its salt can be readily obtained in a reusable form. The method is thus quite advantageous in view of the economy.
