Title: Image forming device
Inventor: INOUE AKIRA
IPC: G03G21/10
Filed: 1999-08-02
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of an image defect or the formation of a ghost owing to lowering of the charge ability caused by the persistent dirt on a charging device 2, over a long period. SOLUTION: Relating to this image forming device, a cleaning member 82 being held in contact with the image carrier is separated from the image carrier surface in the non-image area on the image carrier surface. A charging member of the charging device 2 functions as the toner dispersing member by stopping a drive in the non-image area on the image carrier surface. In the developing device 4, the toner on the image carrier surface is recovered in the non-image area of the image carrier. In the charging device 2 and the developing device 4, the bias being different from the image forming time is applied in the non- image area on the image carrier surface.

Title: Optical pickup device
Inventor: MAEDA TAKANORI
IPC: G11B7/13
Filed: 1986-09-17
Abstract: PURPOSE:To perform an accurate focus servo action in a simple constitution by setting the width of the center area of a three-split photodetector at the prescribed value and at the same time controlling the gains of the detection signal, etc., received from said center area to eliminate the influence of the diffracted light caused by tracks on a disk and the offset. CONSTITUTION:The light beams of a light source are reflected by a half mirror of a parallel plane plate 11 and project on a disk 4. The reflected light beams are made incident on three divided areas of a photodetector 6 respectively via the plate 11. The detection outputs of both areas A and C are added together by an adder circuit 8 and processed by a differential together with the detection output of the center area B received via a gain control circuit 12. Thus, a focus error signal is outputted. In this case, the influence of the track diffracted light caused by the comma aberration, etc., excepting astigmatism of the plate 11 is offset with selection of the width of the area B. This offset value is corrected by the gain control of the circuit 12. Thus, an accurate focus servo is possible in a simple constitution. The same effect is also obtained by controlling the gains of the addition output.

Title: Unit consisting of driving motor and radial piston pump
Inventor: DEIITOMAARU RISHIEN
IPC: F04B17/03
Filed: 1995-08-28
Abstract: PROBLEM TO BE SOLVED: To make the unit inexpensive without requiring any other than a small technical expense, and prevent metal-to-metal contact causing noise by constituting a third bearing arranged adjacent to an armature as sliding bearing made of sintered metal. SOLUTION: When an electric drive motor 3 is switched on, an armature 9 turns a shaft 11, and an eccentric wheel 2 and a bearing ring 31 are eccentrically turned to act on pump piston 33 and 24. The bearing 14 and a shaft-journal 26 of the shaft 11 suppress radial movement of the armature 9 about to the degree conforming to the supporting gap between the shaft-journal 26 and the slide bearing 14. Since the slide bearing 14 is formed as a sintered metal bearing, and filled with semi-fluid lubricating medium, the semi-fluid lubricating medium produces a supporting gap between the sintered metal bearing 14 and the shaft-journal 26. The semi-fluid lubricating medium effectively prevents the metal-to-metal contact of the shaft-journal 26 with sintered material of the sintered metal medium 14.

Filed: 1994-09-14
Abstract: PURPOSE: To enable measuring the molecular weight distribution of hydrophobic hydroxyethyl cellulose(HEC) using gel permeation chromatography(GPC) by using the mixed solvents of acetonitrile and salt water as the moving phase of the gel permeation chromatography. CONSTITUTION: Hydroxyethyl cellulose(HEC) into which a substituent containing quaternary ammonium and being highly hydrophobic is introduced is dissolved in the mixed liquids of acetonitrile and salt water. This solution is used in gel permeation chromatography (GPC) in which the mixed solutions of acetonitrile and salt water are used as the moving phase, so that the molecular weight distribution of the hydrophobic HEC is measured. The concentration of the salt water, which differs depending on the kind and the degree of substitution of the hydrophobic radical in the HEC, is desirably in the range 0.01 to 0.1N. The mixing ratio of the acetonitrile and the salt water is preferably 5:95 to 95:5 (acetonitrile:salt water) in terms of volume ratio.  A system of high- performance liquid chromatography(HPLC) is convenient for use in the measurement of the molecular weight distribution of the hydrophobic HEC by use of the GPC.

Title: Image forming device
Inventor: KANAZAWA MASAHARU
IPC: G03G15/11
Filed: 1997-08-15
Abstract: PROBLEM TO BE SOLVED: To stably obtain a satisfactory image by controlling, based on a detected toner-image-density by an optical reflection-density-detection means, so that a charge-control agent in liquid developer is maintained at a proper concentration. SOLUTION: From the light emission part 6a of the reflection-type photosensor 6, light irradiates a toner image for optical reflection-density- detection formed on a photoreceptor 1, and the reflected light from the toner image is received by a light receiving part 6b. Thus, the density of the toner image on the photoreceptor 1 is detected. A control part CONT compares a given reflection-density reference value (a given reference voltage) and the detection value (output voltage) of the sensor 6. When the detection value is lower than the given reference value, it judges that the density of toner image used for the density detection is higher than a proper density. Accordingly it transmits a signal to a charge-control-agent supply device 47 and make the device 47 supply the charge control agent to the liquid developer D.  On the other hand, when the detection value of the sensor 6 is higher than the specific reference value, liquid carrier is supplied to the liquid developer D from the liquid-carrier supply device 48.

Filed: 1995-08-29
Abstract: PROBLEM TO BE SOLVED: To synthesize character elements of prepared designated style of type and to make a character unified in design in a short time by forming the skelton of a character intended to be formed and designating the style of type. SOLUTION: A fleshless hand-written character is input by a hand-writing means 1, indicated to be resolved into character elements such as left-hand radical or right- hand radical in a character forming region, and the size, the position, and the pattern of the respective character elements are made into data by a cut-out means 2. The resolved respective character elements are standardized by a pattern recognizing means 3 and collated with skelton character elements stored in a skelton character element dictionary part 4 for retrieval by using a pattern matching method, and applicable character elements are decided.  An element synthesizing means 7 reads the pattern data of the respective character elements of the style of type designated by a style of type input means 6 from a character element dictionary part 6, adjusts the position and size so as to conform to the character elements of the hand-written character recognized by the cut-out means 2, and replaces the character elements of the hand-written character by them. By performing this process for all the resolved character elements, the character of designated style of type is synthesized.

Filed: 1987-09-04
Abstract: PURPOSE:To erase adverse influence to communication between a base station and another slave station by stopping the generation of a transmitting burst signal during a constant period determined in advance when there is an error in the CMI signal of a control device to demodulate a signal from the base station. CONSTITUTION:The CMI signal is inputted through an amplifier 17 to a CMI decoder 10 and a signal to be transmitted is decoded and sent from a signal output terminal to a transmitting FF circuit 14. Here, when it is detected by the decoder 10 that the error exists in the CMI signal, an error signal is outputted and supplied to a timing element 11 as an activating signal. The timing element 11 outputs the signal of '1' level during a constant period determined by a time constant circuit 110 and supplies the signal to the clear terminal of the FF circuit 14 as a transmission stopping signal. Accordingly, the transmitting signal is not transmitted to the FF circuit 14 during the constant period and the signal is not sent in a time-slot allocated to the other slave station.
