摘要:
The present invention provide pharmaceutical compositions containing a pyrylium compound, a thiopyrylium compound, a selenopyrylium compound or a telluropyrylium compound or a salt of any of the aforesaid compounds as active ingredient. The compounds are selectively absorbed by cancer cells or similar growths in the human or animal body and can be used to bring about distruction of the unwanted growth on irradiation with light of wavelength 600 nm to 1000 nm. The invention also provides a method for the treatment of the human or animal body which comprises administering the compound to a human or animal and irradiating a locus in said animal where the compound is absorbed in order to kill cells at that locus. It further comprises the use of the aforesaid compound for the making of a medicament for use in the treatment of cancer in humans and animals.

In a reflection type liquid crystal projector, anti-reflection film optimized for the corresponding color (wavelength band) is formed on each of the light passing surfaces of a cross dichroic prism which are opposed to liquid crystal panels of respective colors and the reflectance of each anti-reflection film is made sufficiently small to thereby enhance the contrast of a colored image projected onto a screen by a projection lens.

In a color communication method and apparatus, a desired standard format is designated from among predetermined standard formats on the transmitting side, and the designating information is transmitted to the receiving side along with color image data. As a result, a standard format is read out of a standard-format memory in dependence upon the receiving designating information, this standard format is combined with the color image data and the resulting combination of format and image data is delivered as an output.

The present invention relates to a sheet conveying apparatus with a pair convey rollers arranged upstream of a registration mechanism for correcting a skew-feed of a sheet in a sheet conveying direction that can be abutted against or separated from each other, or can be shifted in accordance with a length of the sheet in the sheet conveying direction. As the result, when the skew-feed of the sheet is corrected by the registration mechanism, a trailing end of the sheet is not restrained.

A generator in a back propagation type neural network having an input layer, an output layer and an intermediate layer coupled the input and output layers forms initial values for connection parameters. A first generator produces an initial value W10 of a weight coefficient of each connection parameter of the intermediate layer from in-class covariant data SW and inter-class co-variant data SB over data inputted to the input layer. The produced values are set into respective synapses of the intermediate layer as connection parameters.

An electronic camera has an image pickup section and a detachable recording section. The image pickup section includes an image pickup element for converting an optical image into an analog image signal. The image pickup section also includes an analog-to-digital converter for converting the analog image signal into digital image signals which are stored in a digital memory within the image pickup section. The detachable recording section includes a digital-to-analog converter for converting the digital signal output from the image pickup section into an analog signal which is recorded in an analog memory within the recording section.
摘要:
A zoom lens comprising four lens groups, the first group for focusing control having a positive focal length, the second group as a variator having a negative focal length, and the third group as a compensator having a positive focal length. The rays emanating from the third group are substantially parallel with respect to a common axis of the lens groups including the fourth lens group which serves as an image-forming lens and which has a positive focal length. The first group has a positive lens of a negative meniscus lens and a bi-convex lens cemented together and a positive meniscus lens, the second group has a negative meniscus lens and a negative lens comprising a bi-concave lens and a positive lens cemented together, and the third group has a negative meniscus lens and a bi-convex lens. The fourth group is composed of a positive meniscus lens, a bi-concave lens, two bi-convex lenses and a negative meniscus lens.
摘要:
An impact line printer is provided with a character drum which has characters such as letters and numerals on the peripheral surface thereof and printing hammers in opposite to the character drum, wherein a printing paper is passed between the character drum and the printing hammers. The printer is further provided with a driven shaft on which is mounted frictional discs. Wheel members are provided, each of which is opposed to and normally spaced apart from each of the frictional discs. The wheel members are selectively brought into contact with the frictional discs to actuate selected printing hammers to effect printing on the printing paper. The printing hammers on normally biased for example by means of spring to keep away from the character drum.
