Title: Developing device
Inventor: TERAI JUNICHI
IPC: G03G15/08
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration caused by wear on the surface of a toner detection sensor and to eliminate erroneous detection even when a cleaning member stops on the surface of the sensor by making the center part of the cleaning member on a side opposed to the sensor recessed. SOLUTION: The cleaning member 18 is formed of one metallic wire having elasticity. The member 18 is constituted of coil spring parts 18a and 18c formed at both ends of the member 18 and a beam part 18b connecting the spring parts 18a and 18c. The spring parts 18a and 18c at both ends, whose center lines of the coils are nearly parallel, are arranged in parallel. The beam part 18b is formed to be recessed in the center part. Since the center part of the member 18 on the side opposed to the toner detection sensor 15 is formed to be recessed, in such a case, the member 18 comes in contact only with a case 15d even when it is opposed to the sensor 15 by its rotation, whereby a non- contact state is always kept on the surface of the sensor. Therefore, the high accuracy of the respective parts 15 not required.

Abstract: PURPOSE: To easily form the needle thread loop of an appropriate size and to prevent sewing defects such as stitch skipping or the like by attaching a member for bypassing a needle thread route to an outer peripheral side from a line connecting the two needle thread holding points of a needle thread loop forming process so as to be able to adjust a position. CONSTITUTION: In this blade type rotary needle thread take-up 1 for which a thread take-up amount adjusting pin 17 is fixed so as to be able to adjust the position, when the thread take-up amount adjusting pin 17 is fixed to the position corresponding to sewing conditions in an oblong hole and a sewing machine is operated, in the forming process of the needle thread loop in the arm shaft turning angle of 120-210 deg., needle thread 7 bypasses a route passing through the thread take-up amount adjusting pin 17 on an outer side from the line connecting the needle thread holding points A and B.  As a result, a needle thread take-up curve 10b, that is the needle thread supply amount of the needle thread take-up 1, is reduced from a standard and a shuttle curve 11, that is a difference with the needle thread pull-in amount of a shuttle, that is the slack amount of the needle thread 7, that is also the size of the needle thread loop, becomes optimum for the sewing conditions.

Abstract: PURPOSE:To obtain the amount of separated out oxygen of a sample wafer with respect to its resistivity measured after being heat-treated for the same period as that for a reference wafer whose initial resistivity is the same as the sample wafer by using a calibration curve of the reference wafer. CONSTITUTION:A sample Si wafer with its interstitial oxygen partially separated as SiO2 is heated to 400-500 deg.C to convert the remaining interstitial oxygen to a donar type, and its resistivity is measured. A reference Si wafer having the same initial resistivity as that for the sample is heated to 800-1,200 deg.C to cause its intersitial oxygen to be separated as SiO2. it is then heated to 400-500 deg.C, the same temperature range as that for the sample. After that the amount of the separated oxygen and the resistivity of the reference wafer are measured. By comparing the sampl's resistivity with that of the reference the amount of the separated oxygen of the sample is obtaned using the calibration curve. Therefore, the amount of oxygen separated as SiO2 can be measured with ease.

Title: Digital controller
Inventor: ONO KOJI
IPC: G05B9/02
Filed: 1985-07-04
Abstract: PURPOSE:To detect the abnormality of a control system as well as a controlled system by determining whether the control system is in proper operation or not by an abnormality detector, and setting a controlled variable to '0' and stopping the control system when the operation of the control system is improper. CONSTITUTION:Deviation pressure En3 is the deviation between target position data Xn1 and the position thetan2 of the controlled system. A servocontrol circuit 12 inputs the deviation En3 and determines a controlled variable In5 for optimizing an evaluation function depending upon the system. Namely, a model estimating circuit 18 finds (k) coefficients 19 of degree (k) of the control system by using the position thetan2 and controlled variable In5. Further, (k) coefficients R of the model of degree (k) of the control system are obtained by a system parameter generator 20 before the control system is put in operation. They are inputted to a parameter comparator 21 and compared with the coefficients 19. The abnormality detector 13 decides whether the control system is normal or not and outputs an error signal 14. A selector 15 selects the output 16 of the control circuit 12 as the output of the error signal 14 when the control system is normal and switches the controlled variable 5 and stops the controlled system when abnormal, thereby suppressing the runaway of the control system.

The respective RGB color light beams made incident on a microlens provided on the incident surface of the optical modulation element 102 at different angles are condensed in a different picture element, optically modulated and emitted from the element 102 as the luminous flux having the image information.  The white light beam of a light source 111 is separated to three color light beams by the one-dimensional binary type diffraction grating 101 and condensed on the picture element of the element 102 corresponding to each color light beam through a micro lens array, so that the utilization efficiency of the light beam is drastically improved.
