An image frame selecting apparatus for a photographic printer which is adapted to designate an image frame to be printed among image frames of a short photographic film. The apparatus includes operating devices the number of which is identical with that of the image frames of the short photographic film photographed and which are arranged in correspondence with the image frames of the short photographic film, the operating devices being adapted to select an image frame to be printed; an image frame designating device for designating the image frame corresponding to an operating portion of an associated one of the operating devices; a conveying device for conveying the short photographic film; and a controlling device for controlling the conveying device in such a manner that the image frame designated by the image frame designating device is positioned to a printing position. This arrangement allows the operator to select an image frame to be printed while collating the position of the selected image frame by means of the operating portion, thereby improving the operating efficiency in selection.

A cyclic olefin addition copolymer includes a structural unit (1) derived from a cyclic olefin compound with a C4 alkyl substituent group and a structural unit (2) derived from a cyclic olefin compound with a C5-12 alkyl substituent group, and optionally includes a structural unit (3) derived from another cyclic olefin compound. The novel cyclic olefin addition copolymers according to the present invention are excellent in melt-formability, transparency and heat resistance, have low water absorption properties, low dielectric constant and low metal content, and are suitably used in optical parts such as optical films. Processes according to the present invention produce the cyclic olefin addition copolymers at high yield with small amounts of catalysts.

A signal detection device allows wavelet transformation of an object signal to be performed in real time by using a real signal mother wavelet. The signal detection device has: an object signal decomposition unit having a lifting scheme structure or a multiple analysis structure relying on multiresolution analysis; a parasitic filter coupled to a desired decomposition filter of the object signal decomposition unit, with the parasitic filter being configured such that a real signal mother wavelet is inputted to the object signal decomposition unit and a generic discrete wavelet transformation is performed, the parasitic filter substantially reproduces and outputs the inputted real signal mother wavelet, and with the real signal mother wavelet being made up of the object signal; means for inputting the object signal to the object signal decomposition unit and performing discrete wavelet transformation using the real signal mother wavelet; and means for computing a wavelet instantaneous correlation on the basis of an output of the parasitic filter.

A structure for attachment of a shield case to a circuit board. Electronic components are mounted at one face of the circuit board. The shield case is for covering the electronic components and blocking electromagnetic waves. The attachment structure includes toe portions, formed to protrude from the shield case, and holes formed in the circuit board, at which the toe portions can be inserted. The toe portions are fixed to the circuit board by being inserted into the holes and soldered to soldering lands at the other face of the circuit board. Thus, it is possible to prevent solder balls and solder flux entering the shield case, it is further possible to reserve space for soldering lands, with sizes that are required for fixing of the shield case, at a rear face of the circuit board, and it is possible to attach the shield case to the circuit board strongly.
摘要:
A process for producing a cycloolefin addition polymer in which one or more cycloolefin monomers can be (co)polymerized by addition polymerization with a small palladium catalyst amount to produce a cycloolefin addition (co)polymer while attaining high catalytic activity. The process for cycloolefin addition polymer production is characterized by addition-polymerizing one or more cycloolefin monomers comprising a cycloolefin compound represented by a specific formula in the presence of a multi-component catalyst comprising (a) a palladium compound and (b) a specific phosphorus compound.
摘要:
Prospective micro calcification points in a radiation image of an object are extracted on the basis of image data representing the radiation image and clustered into cluster areas. A plurality of areas are set in the radiation image, and fluctuation in size and/or fluctuation in density of the prospective micro calcification points in each of the areas is obtained. Detected areas are extracted from the plurality of areas on the basis of the fluctuation in size and/or the fluctuation in density of the prospective micro calcification points in each of the areas, and each interconnected area where a predetermined number of or more extracted detected areas are continuous is set as a cluster area.
摘要:
An anomalous shadow detection system capable of obtaining stable detection capacity across all facilities into which the system is introduced, regardless of variations in the conditions of the image obtaining environments of each facility is provided. An image obtaining means obtains an image of a standard-phantom, and an image readout means obtains phantom-image data thereof. Said phantom-image data is input to an evaluative model detecting means which detects evaluative models contained within the image of the standard-phantom. An evaluating means compares the detected evaluative models to a desired detection level. If the detected evaluative models are of a different detection level than the desired detection level, a parameter setting means resets the detection parameter, depending on the result obtained by the evaluating means 32, and the above processing of the phantom-image data is repeated until the detection result and the desired detection level are the same.

A cyclic olefin having a specific polar group is polymerized by addition polymerization in a hydrocarbon solvent, using a polymerization catalyst component containing (i) a specific transition metal compound, (ii) a Lewis acid compound and (iii) an alkyl aluminoxane, or the cyclic olefin is polymerized by addition polymerization in the hydrocarbon solvent, using the polymerization catalyst component, by further adding at least one aromatic vinyl compound and at least one cyclic nonconjugated polyene compound, or either one of them as a molecular weight modifier, thereby obtaining a cyclic olefinic addition polymer.
摘要:
A shutter device for a camera includes a shutter blade for providing an exposure by opening/shutting a photographic light path, and a shutter drive lever for driving the shutter blade. The shutter device includes a shutter release button. A photometric switch is turned on in response to depression of the shutter release button. A photometric circuit is operated by turning on of the photometric switch, for measuring object brightness. An aperture stop changeover mechanism changes over an aperture stop of the photographic light path according to the photographic light path. A delay structure such as a delay lever detects completion of actuation of the aperture stop changeover mechanism and responsively moves the shutter drive lever.

A detergent composition comprising (a) 0.1 to 95% by weight of a saccharide nonionic surfactant and (b) 0.01 to 5% by weight of an antibacterial agent. The detergent compositions are outstandingly mild to the skin, exhibiting a high antibacterial effect, without influencing or weakening the cutaneous metabolic and barrier functions of the skin. The detergent compositions can effectively restrain the early occurrence of dandruff after shampooing when used as detergents for the scalp and the hair. They also exhibit high antibacterial effect when used as body detergents.
