Human ciliary neurotrophic factor (human CNTF) mutants, in which at least the amino acid residue corresponding to position 153 of wild type human CNTF has been substituted with another amino acid residue in the amino acid sequence encoding human CNTF, exhibit an activity comparable or superior to that of wild type human CNTF. It is therefore expected that the human CNTF mutants would be effective as drugs with improved side effects such as reduction in appearance of an autoantibody, loss of body weight, anorexia, a dry cough, fatigue, etc.In cytokines having sequence similarity to human CNTF and abundant .alpha. helices (GH, PRL, EPO, G- CSF, LIF, IL-6, IL-2, IL-4, GM-CSF), there are further provided mutants in the D1 cap region.

An object of the invention is to provide a rubber modified asphalt type of waterproofing composition which can be used in a normal temperature type of spray waterproofing method and can find its application in waterproofing, moisture-proofing, rustproofing, and filling buildings and structure for engineering works, said waterproofing composition coagulates instantaneously to form a stable yet firm waterproofing layer. This rubber modified asphalt type of waterproofing composition comprises a cationic rubber modified asphalt emulsion and an organic coagulating agent.
摘要:
A semiconductor device which includes a polysilicon gate separated from a semiconductor substrate by a re-oxidized nitrided oxide film in which the concentration of re-oxidized nitride in the film underlying the gate is non-uniform and in which the concentration of nitrogen in the substrate and the re-oxidized nitrided oxide along their interface and underlying the gate is non-uniform. Methods are disclosed of providing the non-uniform concentrations by incomplete shielding of the oxide by the gate during the nitriding and re-oxidizing process.

A method for determining the location and density of bands of biopolymers which are formed by developing and resolving a mixture of biopolymers on a supporting medium in one direction to form a lane of plural bands. The method includes the steps of inputting an image of the lane to a computer in the form of digital data comprising information of location and density, displaying the image, and setting a belt area along the lane which encompasses the aimed bands of the biopolymer. The belt area is then scanned a plurality of times in parallel directions crossing the lane with sufficiently small spacing so as to scan every band present within the belt area, in order to detect relationships of location and density on the digital data in the direction of the lane within the belt area. One dimensional data is then prepared to enable a determination of the location and density of the aimed bands.

A method of making a semiconductor device in which a polysilicon gate is separated from a semiconductor substrate by a re-oxidized nitrided oxide film and in which the concentration of re-oxidized nitride in the film underlying the gate is non-uniform. The concentration of nitrogen in the substrate and the re-oxidized nitrided oxide along their interface and underlying the gate is non-uniform. The non-uniform concentrations are provided by incomplete shielding of the oxide by the gate during the nitriding and re-oxidizing processes.

An image forming apparatus having means for separating a transfer medium bearing member from an image bearing member, which can change fixing speed according to the kinds of the transfer medium employed. As the transfer medium is borne and conveyed to a fixing device by the transfer medium baring member which is separated from the image bearing member, the unfixed toner images are not disturbed by or re-transferred onto the image bearing member and a long conveyed belt is not needed. When the same drive source rotates the transfer medium bearing member and the image bearing member, the apparatus can be further miniaturized.

A distance measuring device for ensuring accuracy of the positional relationship between the optical axis of a light-receiving lens and the optical center of a light-receiving element obtains distance information data by measuring the distance to a target plate which is 1 meter from the distance measuring device. If the distance information is not smaller than 1.625 meter, a switch is connected to one pair of terminals and the difference between reference output data stored in a control circuit and output data of an AF-IC obtained when the distance to the target plate is measured with the switch connected to the pair of terminals is calculated and stored in a memory circuit. When the value of the distance information data is not greater than 0.375 meter, the switch is connected to another pair of terminals, and output deviation data is stored in the memory circuit 11 in the same way. When the value of the distance information value is smaller than 1.625 meter and greater than 0.375 meter, the switch is connected to a further pair of terminals, and output deviation data is stored in the memory circuit in the same way.
摘要:
An image forming apparatus has an image bearing member bearing images thereon and movable, and a transfer medium bearing member provided in pressure contact with the image bearing member and bearing a transfer medium thereon and rotatable. The transfer medium bearing member has a sheet member for bearing the transfer medium thereon, and an elastic layer supporting that area of the sheet member bearing the transfer medium thereon from the inside of the sheet member. A voltage is applied to the transfer medium bearing member to transfer the images on the image bearing member to the transfer medium born on the sheet member. The sheet member has an area not fixed to the elastic layer. The transfer medium bearing member is rotated with a potential difference created between the image bearing member and the sheet member before the operation of transferring the images on the image bearing member to the transfer medium born on the sheet member is started.
摘要:
The present invention relates to an apparatus for forming color toner images on an electrophotographic photosensitive member and for transferring the color toner images onto a transfer member, in which the vibration is prevented from acting on the photosensitive member during a latent image corresponding to each color image is formed, thereby improving the image quality. That is to say, when a peripheral length of the transfer member is L.sub.1, a distance between a light illuminating position of the light information illuminating means on the photosensitive member and a transfer position of the transfer member is L.sub.2, and a length of a maximum image formed on the transfer member is L.sub.3, a relation (L.sub.1 -L.sub.3)>L.sub.2 is established, thereby preventing the vibration from acting on the photosensitive member.
