Abstract: PROBLEM TO BE SOLVED: To provide a bearing device capable of stably rotated in relation to a change of the temperature environment by preventing the adverse effect of the difference between the coefficients of thermal expansion of respective members for constituting a dynamic bearing to a sleeve. SOLUTION: In a bearing device in which a dynamic bearing is used for a radial bearing for supporting load in the radial direction of a rotary shaft 2, and a sleeve 5 made of a resin material is fitted and fixed to the rotary shaft 2 of the dynamic bearing, fitting protrusions 2d, 2e are formed on both upper and lower ends of the rotary shaft 2, the sleeve 5 is fitted and fixed between the fitting protrusions 2d, 2e, and a clearance part G is formed between the sleeve 5 and the rotary shaft 2. Thermal deformation of the sleeve 5 is absorbed by the clearance part G, and the inner peripheral surface 5a of the sleeve 5 and the outer peripheral surface 6a of the rotary shaft 6 are prevented from being brought in contact with each other caused by the temperature change.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: TOMIZAWA NAOMI
IPC: F02D41/14
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To prevent air-fuel ratio control from being degraded in accuracy because of being affected by a miss-fire, and prevent exhaust air from being deteriorated in nature by controlling both feed-back control and air-fuel ratio learning so as to be suspended when the miss-fire is detected, or when the specified period of time has elapsed since no miss-fire was detected. SOLUTION: In both the quantity of fuel injection by a fuel injection valve 6 and a control unit 11 controlling the ignition timing of an ignition plug 8, the pressure of a cylinder at the position of a specified crank angle, is compared with a specified value corresponding to a normal combustion condition based on the output of a cylinder pressure sensor 16. When a miss fire is detected, a timer measuring the period of time which has elapsed since no miss-fire was detected, is reset to zero, and concurrently, an air-fuel ratio feed-back correction value is clamped at a 1.0 where no substantial correction is made, so that an air-fuel ratio feed-back control is thereby suspended. Meanwhile, when no miss- fire is detected, when the specified period of time has elapsed since no miss-fire was detected, the normal feed-back control is therefore executed.

Title: Adjustment device
Inventor: HIROI KAZUO
IPC: G05B11/42
Filed: 1989-02-07
Abstract: PURPOSE:To improve controllability, responsibility and reliability by installing a deviation direction discrimination means, an operation signal level discrimination means and a logic circuit and controlling a switching means on the output- side of a speed type adjustment arithmetic means. CONSTITUTION:A present deviation En outputted from a deviation operation means 11 is transmitted to the deviation direction discrimination means 23. An operation signal MVn-1 in a previous time sampling period is introduced from a speed type/position type signal conversion means with upper lower limit limiting function 14 to the operation signal level discrimination means 24 when the deviation En is outputted or previous to that time. Next, the means 24 compares the signal MVn-1 from the means 14 with previously decided upper lower limit level values, and supplies a high level signal to the logic circuit 25 when the signal MVn-1 is equal or larger than the upper level value H. When a deviation positive direction signal is outputted from the means 23 to the circuit 251, it outputs an off-control signal and off-controls the switching means 24 through an OR circuit 253. Consequently, the output of the speed type adjustment operation means 13 is limited, and controllability, responsibility and reliability can be improved.

The Ni-containing molten iron is shifted to a ladle, and after dephosphorizing and desulfurizing the same, the slag is removed and this molten iron is returned back again to the smelting furnace, and Cr ore is added and oxygen- blowing refining is executed to reduced the Cr ore. Then, after making the molten Ni and Cr-containing iron, the slag is removed again and the molten Ni-Cr series stainless steel is produced at a low cost by decarburize-refining the result with the oxygen-blowing.

Title: Noise detector
Inventor: IWAI MASARU
IPC: H04B10/00
Filed: 1986-02-12
Abstract: PURPOSE:To detect noise in on-line easily by sending an optical signal and an electric signal to a transmission line comprising an optical fiber and a conductor wire and comparing the induction of noise inbetween. CONSTITUTION:The electric signal from an oscillator 3 is inputted to a comparator 6 through the conductor 2. On the other hand, the electric signal of the oscillator 3 is converted into an optical signal by an E/O converter 4, converted into an electric signal by an O/E converter 5 through an optical fiber 1 and inputted to the comparator 6. The comparator 6 compares both the signals, while the optical signal through the optical fiber is sent without being affected by external noise, but the electric signal through the conductor 2 is affected by the external noise and superimposed on the electric signal, then in comparing the both, the noise can be detected. The optical signal side is used as the reference in such a way to compare the electric signal side to detect the noise easily in on-line.
