Title: Display device for processing of chromatograph detecting data
Inventor: MITO YASUTAKA
IPC: G01N30/86
Filed: 1981-06-30
Abstract: PURPOSE:To facilitate reading of various types of information through recording of a change in vector, by a method wherein each 2 pairs of sampling data of detecting outputs from a plural number of detectors are two-dimentionally recorded in each dimentional direction. CONSTITUTION:A photo diode array 7 is scanned through a control circuit Cp through flowing of only a carrier fluid to a flow cell 3, and a current data is written in a memory M1. Then, through flowing of a column flow fluid to the cell 3, the control circuit Cp renews a content of a memory M2 into an up-to- date data. A memory content of a set, corresponding to different wavelengths of the memories M1 and M2, is flowed through the control part Cp, a computing part Cu decides an absorbance in 2 sets of wavelengths, and if the absorbance of each wavelength is two-dimentionally recorded in an x- and a y-coordinate direction, a vector change record is recorded in an x y recorder. The recording in the direction of a change in vector, showing concentration classified by a type and a length of a sample, facilitates recognition of a chromatograph pattern based on reading of various types of information.

Title: Creep preventing roller bearing
Inventor: ITOU AKINORI
IPC: F16C33/58
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To make a creep preventing roller bearing to resist a severe load condition without changing the dimension of its outside diameter by arranging annular band mounting grooves in the outside diametral surface of the outer ring of a double row roller bearing, and mounting in these grooves, bands formed of materials having larger coefficient of liner expansion than the outer ring. SOLUTION: Two band mounting grooves 5 are formed in the outside diametral surface of an outer ring 2, and ringlike bands 6 are mounted in the grooves 5. The bands 6 are formed of materials having larger coefficient of linear expansion than the outer ring 2, for example, a synthetic resin such as polyphenelenesulfide resin, and the inner/outer rings 1, 2 and rolling bodies 4 are formed of bearing steels. Even through fitting looseness is developed by the difference of the coefficient of linear expansion between a housing formed of aluminum and so on and the outer ring 2 accompanied by temperature rise, the bands 6 are thermally expanded, thereby the fitting looseness is corrected and creep is prevented.  Also, this creep preventing roller bearing is arranged in a double row, therefore cross sectional height can be lowerly suppressed even though load ability is increased, the outside diametral dimension of the housing can be diminished, and a compact mechanical design is possible.

Abstract: PURPOSE:To obtain high image quality and to prevent the occurrence of toner filming by using specific toners in an electrophotographic method having a development method featuring a small size and high performance. CONSTITUTION:The magnetic toners formed by adding external additives consisting of inorg. particles which have an average grain size of 0.1 to 4mum and true sp. gr. of 5.0 to 8.5g/cm<3> and negative charge type hydrophobic silica particulates which are 50 to 350m<3>/g in the BET specific surface area by nitrogen adsorption and are subjected to a surface treatment by silicone oil to the surfaces of the toner base material are used. Since the inorg. particulates have the specific grain size and true sp. gr. in such a manner, the inorg. particulates have an effect of loosening the flocs of silica and are capable of uniformly dispersing the silica particulates at the time of mixing the inorg. particulates with the silica particulates. AC voltage superposed with DC voltage of 0... is applied to the electrode roller 8 at the time of passing of the non-charged area of the Photosensitive 1. The AC voltage applied with DC voltage of-350V is applied to the roller at the time of passing of the photoreceptor 1 written with the electrostatically charged electrostatic latent image. The toners 7 sticking to the non-image parts of the electrostatic charging parts of the photosensitive 1 are then recovered on the electrode roller 8.
