Title: Fixing device
Inventor: OKABAYASHI EIJI
IPC: G03G15/20
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent the surface temperature of a fixing roller from being lowered in the early stage of consecutive paper passing operation and to consistently fix a color image with high glossiness by shortening a toner image fixing cycle in accordance with the increase of the number of toner image fixing times. SOLUTION: A fixing cycle control means controls so that the toner image forming cycle may be shortened in accordance with the increase of the number of toner image forming times. Namely, a control substrate performs paper passing operation at a time interval being a1 when the passing of recording paper S is started, and performs the paper passing operation at the time interval which gets shorter according to the number of paper passing times such as a2, a3, a4, a5 and a6 thereafter. When the paper passing interval gets to a6, the paper passing operation is performed at the paper passing interval in which a6 is set as a fixed cycle thereafter. Thus, when fixing is consecutively performed, the quantity of heat supplied by a heater till performing next fixing gets large just after starting the fixing, and the sufficient quantity of heat is stored in a thermal fixing means.  Therefore, the temperature of the thermal fixing means is not lowered at the time of starting the fixing, and the thermal fixing means is always kept at a temperature high enough to perform fixing.

Title: Instrument for measuring contact resistance value of keyboard contact
Inventor: KOGAI YUKIKAZU
IPC: G06F3/02
Filed: 1986-09-13
Abstract: PURPOSE:To surely operate a measuring instrument with a simple constitution to measure the contact resistance value of a keyboard contact by flowing a constant current from one side of a terminal train to measure voltages in both ends of the contact and detecting the contact resistance of the contact. CONSTITUTION:All contacts of a keyboard contact group 1 are turned on by a prescribed method like pressing to a plane plate. Connections of switches 8 to a transverse terminal row are fixed and those to a longitudinal terminal row are successively switched. They are switched in the order preliminarily reported to a microprocessor or by switching relays or the like by the control of the microprocessor. Since a constant current flows from a constant current source circuit 6 through the contact resistance of the contact which is changed in the transverse direction at each time of switching, voltage drop is detected. The voltage drop value is amplified by an amplifier 7 to facilitate performing the following processing and is measured by a microprocessor 2 or the like. The contact has a large contact resistance value and is judged too be defective if the voltage drop value larger than a prescribed value is generated for this contact.

Filed: 1990-08-18
Abstract: PURPOSE:To attain low power consumption while enhancing impulse response and step response by providing a 2nd variable impedance means to an emitter of an input transistor(TR). CONSTITUTION:A 2nd variable impedance means comprising an N-channel MOSFET Q11 is provided to an emitter of an input TR T1 being a component of a phase split circuit of an SPL(Super Push-pull Logic) circuit and the MOSFET Q11 is turned on by an output signal SO going to a high level when an input signal SI goes to a low level to discharge a stored charge in a capacitor C1 rapidly. Moreover, when the input signal SI goes to a high level, the MOSFET Q11 is almost turned off and an operating current of the phase split circuit is limited to a small value. Thus, while the power consumption of the SPL circuit is kept low, the impulse response and step response are enhanced.
