Abstract: PURPOSE:To instantaneously and easily change a target image density and further to stably keep an image density after the change as well by changing the target image density in accordance with an instruction from an operating part and issuing the command to a toner concentration changing part. CONSTITUTION:A developing bias voltage changing part 2 receives an image density changing instruction from the operating part 1 to decide the changed value of a developing bias voltage and changes the value of the developing bias voltage applied to a developing unit 6 by a developing bias voltage changing instruction. On the other hand, an image density target value changing part 3 receives the image density changing instruction from the operating part 1 to decide the changed target value of the image density in accordance with this instruction and transmits the decided value to the toner concentration changing part 5. It instructs a toner supplying part 7 to provide the new target image density and the developing part 6 as well. It receives the supply of the toner from the toner supplying part 7, corresponding to the new target image density and changes the toner concentration by sufficient stirring.

Title: Liquid developer and image forming method
Inventor: NAGASE KOICHI
IPC: G03G15/10
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To prevent toner from being attached to a heat roller and to obtain an excellent fixed image even when a fixing is executed by the heat roller by including the specified quantity of silicone oil having the viscosity of a specified value. SOLUTION: The silicone oil whose viscosity at 25 deg.C is >=1 cSt and <=50 cSt is included by 0.1-5 wt.%. When the viscosity is <1 cSt, the toner is not sufficiently prevented from being attached to the heat roller. When the viscosity is >50 cSt, the silicone oil is not sufficiently mixed in developer. As the result, it occurs that a droplet-state defect is caused or desired printing density cannot be obtained because developing density is lowered when an electrostatic latent image carrier is developed by the liquid developer. When the content of the silicone oil in the liquid developer is <0.1 wt.%, the toner is not sufficiently prevented from being attached to the heat roller. When the content is >5 wt.%, an image on a transfer body becomes sticky after the fixing is executed.

IPC: H01L23/522
Filed: 1986-05-23
Abstract: PURPOSE:To minimize the probability of occuring a disconnection of a metallic interconnection on the peripheral part of an opening conventionally causing a problem in case of connecting by the metallic interconnection through the opening by a method wherein the opening of an insulating film is shaped into a slope at the lower part of insulating film while into a perpendicular wall at the upper part thereof. CONSTITUTION:An opening 105 is shaped into a slope at the bottom thereof i.e. on the surface of the first Al 102 while into a perpendicular wall at the upper part thereof. Such a shape of opening 105 can be processed easily by means of optimizing the etching requirement in case of forming the opening 105. In other words, it suffices that firstly, the etching process is started meeting the requirement for approximate etching speed of an SiO2 film and a photoresist and secondly for the etching speed of SiO2 film much higher than that of photoresist until the first Al 102 is exposed. Through these procedures, a metallic interconnection in sufficient thickness can be formed on the peripheral part 106 of opening to reduce the probability of disconnection markedly.

IPC: G06T1/00
Filed: 1990-05-10
Abstract: PURPOSE:To eliminate the need for erasure processing of an undesired picture and to improve the operability by providing a designation means designating variably a picture input width and an image pickup optical system receiving a picture by a picture input width designated by the designation. CONSTITUTION:The user sets a picture input width to an optional width by moving indexes 2, 3 and moves a case 1 toward this side on a picture being an input object while depressing a start button 6. In this case, in interlocking with the set width by the indexes 2, 3, light emitting elements in the inside of the case 1 are lighted in response to the same width as the set width and the light radiates the picture, then only the picture data for the designated range by the indexes 2, 3 is outputted from a photodetector being a photoelectric conversion means receiving the reflected light from the picture. Since the user sets the input picture width optionally freely and inputs only the picture of required and minimum quantity to a word processor or the like, the delete processing of undesired picture is not required and the operability is improved.

Filed: 1990-05-08
Abstract: PURPOSE:To average the thickness of a board and to prevent the generation of a crack by interposing a thickness control member whose height gradually reduces from the central part of a crosshead or a slide to the peripheral part thereof between the crosshead and an upper mold or between the slide and a lower mold. CONSTITUTION:Green sheets are stacked in a molding chamber 11 having a square hole shape formed to a lower mold 3b in a predetermined order and heated by a hot plate 4 while pressed between the lower mold 3b and an upper mold 3a by extending a hydraulic cylinder 9 to be bonded mutually under pressure to form a ceramic substrate 10. Herein, since the height of each of thickness control members 5 is gradually reduced from the central part of a crosshead 2 or slide 3 toward the peripheral part thereof, the upper and lower molds 3a, 3b are deformed at the time of pressing so as to follow a change in the heights of the thickness control members. Therefore, the distribution of the pressure acting on the ceramic substrate changes so that the pressure is high at the central part of the substrate and becomes low at the peripheral part thereof and generated internal stress is averaged between the central and peripheral parts.
