Title: Temperature control method
Inventor: MATSUKI NOBUYUKI
IPC: H05B3/00
Filed: 1990-09-25
Abstract: PURPOSE:To evade large over-shoot by setting an initial control temperature predicting the response delay of a sensor, and making the intermediate control temperature of a body to be heated gradually close to a target control temperature when the detected temperature of the sensor reaches the initial control temperature. CONSTITUTION:The sensor equipped with a thermister 1 is installed around a heating roller 3 for fixture equipped with a heater 2 in the inside, and a data showing a sensor temperature is applied to a central processing unit CPU 5. When controlling the temperature of the heating roller 3, the initial control temperature is set lower than the target control temperature corresponding to the temperature when starting the control, and after the detected temperature of the sensor reaches the initial control temperature, the intermediate control temperature is set between the initial control temperature and the target control temperature of the heating roller 3. Then, this intermediate control temperature is gradually increased with the passage of time and made close to the target control temperature. Thus, even when the temperature increases fast, the large over-shoot caused by the response delay of the sensor for temperature detection can be evaded.

Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To minimize a layout area and reduce noise that is caused by charge and discharge current of output load of an output buffer about an output buffer circuit of a semiconductor device by serially connecting resistance whose values are separately different between a plurality of switching elements and power supply. SOLUTION: In an output buffer circuit, resistance whose values are separately different are serially connected between the plurality of switching elements and power supply. That is, QP1 to QPn are switching elements, e.g. p-channel MOS transistors and are parallelly connected between a VDD and an output terminal Dout via resistance R1 to Rn. Also, QN1 to QNn are switching elements, e.g. n-channel type transistors and are parallelly connected between a VSS and the terminal Dout via resistance r1 to rn. Because a timing delay circuit, etc., is not needed due to the structure, it becomes possible to reduce a layout area.

IPC: G03G15/08
Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To obtain such a roller having low hardness that a developer permeating into the roller is easily moved and diffused and that carrying property of a developer is improved by controlling the average roughness of the surface of an elastic layer comprising a formed body to <= a specified value. SOLUTION: First, a roller having an elastic layer 3 comprising a formed body around a shaft 2 is inserted under pressure into a cylindrical member having a smaller inner diameter than the outer diameter of the roller. Which the roller is inserted into the cylindrical member, the cylindrical member is heated. After heating, the member is cooled and the roller is taken out from the cylindrical member to obtain a developer carrying roller 1'. In the developer carrying roller 1', it is required that the average surface roughness of the elastic layer 3 is <=50 μm. If the average surface roughness exceeds 50 μm, it is not preferable because enough nip width inbetween a developer carrying body such as a developing roller is not obtd., or the foamed body on the surface is scraped and mixed as a foreign matter in the developer.
