Title: Chromatography separation method and chromatography apparatus
Inventor: HAMANO YOSHIMASA
IPC: G01N30/88
Filed: 1989-01-23
Abstract: PURPOSE:To enable a chromatography separation of sulfocysteine by using a separation column packed with a basic anion exchange resin and an acid eluate. CONSTITUTION:A separation column 5 packed with a strong basic anion exchange resin is arranged in a thermostatic cell 6. Solution tanks 1 and 2 hold citric acid buffers different in concentration of sodium and these buffers are sent to the column 5 singly or being mixed through a feed liquid pump 3 and an injector 4. A ninhydrine solution of a liquid tank 7 fed with a nitrogen gas 9 and a buffer of a liquid tank 8 are mixed in the same amount to be sent to a mixer 12. The mixture is converged with a column elution by the mixer 12 to which a reagent for amino acid color formation is fed beforehand and passes through a reaction coil 13 to detect absorbance with an absorption photometer 14. Then, a detection signal is processed with a data processor 15 and a chromatogram display and the results of quantitative calculation are outputted thereby enabling chromatography separation of sulfocysteine satisfactorily.

Title: Solid-liquid separator
Inventor: NISHIDA TETSUO
IPC: B01D21/26
Filed: 1986-01-24
Abstract: PURPOSE:To efficiently separate a solid material from drainage by synergistic effect of both a primary flow rotating in the inside of a separation tank having a specific structure and a secondary flow fluidizing in the vertical direction in the inside of the separation tank by providing an internal cylinder to the center part of the separation tank. CONSTITUTION:Drainage 7 introduced into the inside of a separation tank 1 from the tangential direction through an inflow port 5 is rotated in the inside of the the separation tank 1 along an outside wall without causing a turbulent flow, and treated liquid is discharged through a discharge port 9 without being allowed to directly collide against the introduced drainage. Also the primary flow S rotating in the inside of the separation tank 1 is slowly rotated by the resistance of the surface of the internal cylinder 12 and the degree in change of circumferential velocity of the primary flow S is made large in the range to the inside from the outside of the separation tank 1. As a result, the generation of a secondary flow G which is fluidized in the vertical direction in the inside of the separation tank 1 and is effective in solid-liquid separation is made violent and the solid material contained in drainage is efficiently settled on the bottom 3 of the separation tank 1 by synergistic effect of the primary flow S and the secondary flow G and collected in a reservoir 4 of the solid material through a transfer passage 17 of the solid material.

CONSTITUTION:A throw-in port 2a for materials to be regenerated such as runner and poor molded articles just after the molding by means of a molding machine and a feed port 3a of a feed device 3 for unused materials are provided on a crusher 5, whereby both materials are crushed at the same time into particles of specified size or smaller, while both materials are mixed with each other and also feed quantities of said unused materials fed by means of the device 3 are controlled so that feed quantities required for a molding machine can be provided. As a result, other mixing device is not needed and work for measuring the ratio between both the materials to keep said ratio at a certain ratio is not required. Further, if this crusher and a molding machine are interconnected by means of an automatic material transportation means, drying period and power for a dryer can be saved since material to be regenerated is not humidified.

Thereafter, lean operation is permitted at a step H. During the lean operation, the base learned value or the normal learned value is selected at a step G, whichever may more enrich an air-fuel ratio. The open control of the ratio is, then, performed at a step F, using the selected value.

Abstract: PURPOSE:To improve the road-damage preventing effect by specifying the width of a lug, interval in the peripheral direction and the inclination angle of lug plane on a tire stepping-in side on the lugs arranged right and left in the direction of tire width from a projecting rib formed in the center division of a tread reinforced with carcass. CONSTITUTION:A tire T is equipped with a projecting rib 2 having a height of h1 in the peripheral direction in the tread center division of a tire body 1. Said rib 2 has a small width of W1 in consideration of the stability in straight advance on traveling and has cut parts 2a and projection parts 2b on the outer periphery so as to be discontinuous in the peripheral direction. The lugs 3 which push-out relatively largely in the direction of width from the projecting rib 2 are formed to the right and left. Each lug 3 is formed so that the width W2 is 1.5-3.0 times half of the max. tire width W0 and the interval h2 in the peripheral direction is 2.5-4.5 W0. The inclination angle alpha of the lug plane 3a on the stepping-in side of the tire T is set within a range of 10-50 deg. with respect to the normal line of the tire.

Title: Piston ring
Inventor: SATO YOSHINORI
IPC: F16J9/26
Filed: 1989-01-24
Abstract: PURPOSE:To provide a piston ring with no peeling-off in a hardened layer and satisfactory sealing by forming a frame coating layer with excellent abrasion resistance and seizure resistance on the whole outer periphery other than a part of section next to the edge of an abutment. CONSTITUTION:The abutment edge of a piston ring element 9 is formed so that its surface may extend aslant in the up direction, and in the section next to the center of the abutment edge 10, a hole 11 is formed from the single face of the top or bottom, into which a piano wire or the like is inserted so that the abutment edge may be maintained in a close-contact condition. By rotating the piston ring element 9, and jetting abrasion resisting material and seizure resisting material through a flame coating gun 15 to apply them to the outer periphery of the piston ring 9, a jet coating layer is formed. At this time, no flame coating layer is formed in the range 4 of a given distance from both the edges of the abutment. Since no flame coating layer exists near the abutment, there is no fear of the layer peeling off or chipping. Moreover, the flame coating layer is formed to top and bottom edges over the outer periphery of the piston ring, thus improving seal quality.

In a detector 86, a transmission channel estimate means 86a applies carrier phase synchronization detection to an output from an adder 84 and gives its output signal to a multiplier 86c via a complex conjugate means 86b. The multiplier 86c applies amplitude weighing to an output of the complex conjugate means 86b and an output of the adder 84 for the provision of rake synthesis at a succeeding adder 88. The adder 88 applies weighting to an output of each multiplier 86c of three paths for the rake synthesis. A decision device 90 decides a most probable transmission symbol from an output of the adder 88.

Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of image quality and to ensure the satisfactory resolution of a monitor TV by sequencially switching the video signals which are inputted at each horizontal scanning time and thinning the horizontal scanning lines to composite video signals of plural monitoring cameras. SOLUTION: Selectors 81 and 82 select the video signals which are received from monitoring cameras 11 to 14. The horizontal scanning lines are thinned to composite the video signals of cameras 11 to 14 into the video data into a single frame which are recorded in frame memories 65 and 66. A clock generation means 61 sets the read clocks of both memories 65 and 66 at a speed higher than those of the write clocks by an integral multiple. Thus, the analog video signals which composite the images photographed by the cameras 11 to 14 can be produced from all the video data of every scanning line. Then the video signals which correctly reproduce the images photographed by the cameras 11 to 14 are outputted from an image-compositing circuit 50.
