Title: Automatic gain control system
Inventor: UCHIDA TOMOAKI
IPC: H03G3/20
Filed: 1987-06-15
Abstract: PURPOSE:To attain automatic gain control to an amplitude level of an input analog signal by arranging a variable gain amplifier changing the gain of the input analog signal to the pre-stage of an A/D converter and supplying the converted analog signal to the variable gain circuit. CONSTITUTION:An analog signal coming to an input terminal Inp is amplified by a variable gain amplifier 11, converted into a digital signal by an A/D converter 6 and outputted to a signal processing circuit 7 and fed to a level detection circuit 12, where the amplitude level is detected. The difference of the detected signal with an output voltage, that is, a reference value of a reference level setting circuit 14 is amplified by a differential amplifier 13 and an output signal of the differential amplifier 13 is outputted to a D/A converter 15. An error signal converted into an analog signal is impressed to the variable gain amplifier 11 via an LPF 16. Thus, the amplification factor of the variable gain amplifier 11 is changed in response to the error signal and the gain control is attained so that the output of the level detection circuit 12 is equal to the reference value of the reference level setting circuit 14.

Title: Thermal recording material
Inventor: MIYAJIMA SHIGERU
IPC: B41M5/327
Filed: 1984-07-17
Abstract: PURPOSE:To provide a recording material having high sensitivily, capable of expressing gradations and suitable for recording images with halftone, by using a specified leuco dye and a specified color developer. CONSTITUTION:One or more fluoran compounds of formula ( I ), wherein each of R<1> and R<2> is 1-4C alkyl, is used as a leuco dye, and a combination of 4,4-dihydroxydiphenylsulfone and 1,7-di(4-hydroxyphenylthio)-3,5-dioxaheptane is used as a color developer for developing the color of the dye when being heated. Though 1,7-di(4-hydroxyphenylthio)-3,5-dioxaheptane is excellent in color forming property under low given energy, the developed color density obtained is rapidly increased with an increase in given energy. When it is combined with 4,4-dihydroxydiphenylsulfone which is a high melting point color developer, the developed color density can be increased at a moderate gradient. Accordingly, since the combination of the specified two color developers differing in melting point is used for the specified leuco dye, the thermal recording material thus obtained has high sensitivity, is free of ground fogging, and is rich in gradation-expressing property.

Abstract: PURPOSE:To prevent waste toner from falling and scattering from a joint part by inhibiting the joint part of a conveying means from being disconnected until the reverse driving of a waste toner conveying means is completed. CONSTITUTION:The waste toner which is removed by a cleaner means 16 from the surface of a photosensitive body is normally fallen and stored in a recovery container 100 through the conveying means. When a device main body part 1 is opened or the joint part is disconnected by interlocking with the drawing-out operation of a PC unit 10, etc., the conveying means is driven in the opposite direction from the normal conveying direction before the disconnection and the waste toner is moved back away from the joint part. At this time, the joint part is inhibited from being disconnected until the opposite-directional driving of the conveying means is completed. Consequently, the joint part can be disconnected for the 1st time after the waste toner moves back away from the joint part completely and the toner is prevented from falling and scattering from the joint part.

Filed: 1987-06-16
Abstract: PURPOSE:To prevent a misdecision from being made and to take a measurement at low cost by scanning a binarization light emission point image which is obtained by processing the image of the light emission point of a light emitting element on a mesh line, and detecting the change point where this line crosses the binarization light emission point image edge part. CONSTITUTION:The light emitting element 7 is fixed to a jig and an image of the light emission point is picked up by a video camera 2. The image signal of the camera 2 is converted by an image processing circuit 4 into a binarized image, which is inputted to a CPU 5 to calculate the center of gravity G(X0,Y0). Then the binarized image is scanned as to one of X- and Y-directional lines lXi and lYi (i=integer) constituting a mesh. Then the point where the line crosses the edge part of the light emission point, i.e. change point C is detected and the number N of change points C is counted. When N>=3, it is decided that a Z-axial (direction connecting the element 7 and camera 2) position is over, i.e., not within a measurement range. When the number N is less than 3, a next line is scanned. When all lines are scanned completely, the area of the light emission point image is calculated to find the deviation on the Z axis.
