IPC: G03G15/08
Filed: 1990-09-14
Abstract: PURPOSE:To stably obtain a clear image without density lowering and fogging by varying at least two or more toner density control levels according to one or more conditions among toner supplying time, an environmental condition, and image area rate of an image which is developed. CONSTITUTION:A sensor 12b to detect the light quantity of reflected light and the sensor 12c to detect the light quantity from a lamp 12a are attached on the housing 17 of a detecting member 12. When the voltage of light detected by the sensors 12b and 12c are set as Vb and Vc and the developer of specified toner concentration exists, a conversion circuit is adjusted to be Vb=Vc, then with respect to the increasing and decreasing of the toner concentration the Vb is increased and decreased, and the Vc is always constant. Therefore, by repeating actions to turn off the toner supply to a developer housing part C when Vb>=Vc and to turn on the toner supply when Vd<Vc, the toner concentration of developer can be controlled to a specified value. At such a time, this device has at least two or more toner concentration control levels, and the control level can be changed according to the electric charge amount of the toner.

Four types of gas concentration ratio are selected, and these concentration ratio are plotted on a radar chart, using rectangular coordinates comprising x- and y-axes to determine the correlation between the gas concentration ratios and abnormal phenomena. Meanwhile, based on the ratios of gas concentrations in various abnormal phenomena, the types of abnormal phenomena are correlated to the gas concentration ratios and stored together with a basic graphic pattern in advance. Measured graphic patterns are checked compared and compared with against the basic graphic pattern for detecting the occurrence of any abnormality. Thus, abnormality in the OF cable is detected exactly.

Abstract: PURPOSE:To improve the stability of rotation without generating the inclination of an axial center and to facilitate the change in the design of an attenuation characteristic by providing a means for attenuating the vertical movement of a rotating body with a small hole which is opened on a stationary shaft and communicates with an air supply path. CONSTITUTION:This rotary polyhedral mirror device is formed with the rotating body 2 of a capped cylindrical shape to be fixably fitted on the stationary shaft 1 and is formed with an attenuating means 9 consisting of the orifice which is opened atop 4 the top wall 10 of the stationary shaft 1 and communicated with the flow passage 8a of the air supply path 8 on this top wall. The volume of the space segmented within the rotating body 2 is fluctuated by the upper surface 4 of the stationary shaft 1 when the rotating body 2 and the polyhedral mirror 3 move vertically during rotation. The air to be supplied into the rotating body 2 via the air flow passage 8a flows into this space. The flow of the air arises within the attenuating means 9 between this space and the air flow passage 8a when the change in the volume of the space arises. The flow of the air is suppressed by the flow passage resistance of the attenuating means 9 in such a manner, by which the energy of the vertical movements of the rotating body 2 and the polyhedral mirror 3 is absorbed and the vertical movements thereof are attenuated.

Title: Optical fiber cable
Inventor: SAITO SHIN
IPC: G02B6/44
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to package coated optical fibers to a higher density in wiring of these coated fibers by adopting the constitution to strand the coated fiber ribbons formed with secondary coating layers on the circumferences of the coated optical fiber ribbons around a central member. SOLUTION: The coated fiber ribbons 8 are stranded around the central member 6 consisting of a tension member 1 and a coating layer 2 and a protective layer 4 and a sheath 5 are successively formed on the outer periphery. The coated fiber ribbons 8 are formed with the secondary coating layers on the circumferences of the coated optical fiber ribbons 3. The coated fiber ribbons 3 are protected by the secondary coating layers, by which the bending rigidity and tensile strength are assured and, therefore, there is no need for using reinforcing tubes and this optical fiber cable is usable for wiring by mounting a connector to the coated fiber ribbons 8. Since the coated fiber ribbons 8 are smaller in diameter than the conventional coated fibers on which the reinforcing tube is put, the higher wiring density is attained.

Title: Curve generating method
Inventor: KUDO NORIKO
IPC: G06T11/20
Filed: 1989-09-20
Abstract: PURPOSE:To generate a curve of high quality at a high speed by obtaining the minimum time interval where the final cumulative error is set smaller than an allowable level and therefore showing the curve with high accuracy. CONSTITUTION:An error epsilon included in a matrix M(t0) of the initial value shows an amount E that is accumulated up to an end point Pn with repetition of the addition. Then a function (f) with which the total number (n) of curve forming points P0... Pi and Pi + 1... Pn is equal to a variable is decided. The total number nmax of those curve forming points which is maximized when the value E of the function (f) is smaller than the allowable value Emax is selected. Then the time interval deltamin is obtained from the selected number nmax as well as the time lengths tn - t0 set between the start point P0 and the end point Pn of a curve 100. Therefore a differential matrix is computed based on the time interval where the final cumulative error is smaller than the allowable error. The time interval is also calculated by a differential matrix method. As a result, the curve of high quality is generated at a high speed.
