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.

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.

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.

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.

An apparatus for detecting contact between a contact detection member and a rotating body such as a grinding wheel rotably carried on a wheel head which is movable toward the contact detection member in a grinding machine for example. The apparatus comprises an AE sensor, a rectangular pulse generator, a sampling circuit and a processing device such as a microcomputer. The AE sensor generates an electric signal in response to vibration of the contact detection member. The rectangular pulse generator outputs a rectangular pulse whose duration corresponds to that of vibration. The sampling circuit delivers to the processing device an output indicating the duration of the rectangular pulse. The processing device processes the output delivered thereto so as to decide the occurrence of an actual contact between the rotating body and the contact detection member.
