Title: Power-on clear circuit
Inventor: MACHIDA TOORU
IPC: H03K17/22
Filed: 1984-03-13
Abstract: PURPOSE:To obtain an output pulse having a desired time width by connecting at least >= one MOSFET to an MOSFET and adding one MOSFET. CONSTITUTION:At least >= one N-MOSFET8 whose gate and drain are connected is connected in series with an N-MOSFET3. Further, an N-MOSFET9 where a prescribed voltage is impressed between the gate and source is added. Thus, a potential of a contact 4 is decreased to n-times (n is the number of FETs 3-8) the threshold voltage rapidly after application of power and then the potential is decreased linearly to the time comparatively slowly. Thus, the output pulse having a desired time width is obtained by setting an inverted voltage of an inverter 5 in the voltage range dropped linearly.

Title: Heater
Inventor: SHINDO HIROBUMI
IPC: F24C7/04
Filed: 1989-02-28
Abstract: PURPOSE:To enable a comfortable feeling for heating and a clean atmosphere to be continued by allowing electric heat-generating members to radiate the total radiant heat rays generated therefrom for a fixed period of time after power has been supplied thereto, and thereafter by assigning a part of the radiant heat rays to the activation of an air cleaning catalytic material. CONSTITUTION:Radiant heat radiated from electric heat-generating members 1 is irradiated onto a reflecting plate 3 and reflected in front of the reflecting plate 3 for a fixed period of time immediately after power has been supplied, without being substantially interrupted by a short strip-shaped air cleaning plate 5 because it is aligned side by side with tubular electrical insulating members 4. Thereafter, a driving means 9 is operated by a timer or the like, and the air cleaning plate 5 that has so far been in a state parallel to radiant heat rays from the electric heat-generating members 1 is turned 90 deg. by support shafts 8 provided at both ends of the air cleaning plate 5 as fulcrum shafts, and is opposed to the tubular electrical insulating members 4. Consequently, the radiant heat rays that have been radiated from the electric heat-generating members 1 toward the reflecting plate 3 side are irradiated onto the air cleaning plate 5 and absorbed thereto, thereby heating the same. Furthermore, since the air cleaning plate 5 is positioned between the tubular electrical insulating members 4 and the reflecting plate 3, the surface temperature of the air cleaning plate 5 is elevated to 250 deg.C or higher in the case where it is opposed to the tubular electrical insulating members 4, and an air cleaning catalytic material 7 is activated, whereby carbon monoxide, hydrocarbon, ammonia gas, etc., in air are decomposed and cleaned.

Filed: 1989-02-28
Abstract: PURPOSE:To easily cope with the increase of input/output devices by adding the input/output control firmware via a rewritable memory based on the device identification information. CONSTITUTION:A device identification information reading circuit 41 receives a reset signal via a host interface (d) and starts an input/output control circuit 42. Then the circuit 42 reads the device identification information 21 on an input/output device 2 and stores it in a device identification information store circuit 7. The circuit 7 produces the address and the data length of an EPROM 8 storing the corresponding control firmware out of the stored information 21. An access circuit 6 stores the firmware into a control memory 43 of an input/output control adaptor 4 from the ROM 8 via a bus line (c) based on the produced address and data length. Thus it is possible to easily cope with the increase of input/output devices 1 by adding the input/output control firmware.

Title: Image forming device
Inventor: YAMAMOTO TAKEMI
IPC: G03G21/00
Filed: 1988-03-01
Abstract: PURPOSE:To prevent jamming from occurring in an image forming device by changing temperature and relatively changing moisture so that the temperature and the moisture in the image forming device can be adjusted. CONSTITUTION:The signals of voltage values in proportion to the temperature and the moisture are outputted from a temperature detection part 41 and a moisture detection part 42 respectively. Either the signal of temperature or the signal of moisture is selected by an analog multiplexer 35 and inputted in an A/D converter 36 to be converted into a digital value, the inputted in a CPU 37. The CPU 37 transmits a control signal to a control logic 43 so as to incorporate the signals of temperature and moisture alternately. Then, it fetches the data on an allowable temperature from a ROM 38 based on the data on both of temperature and moisture and controls a solid state relay 40 so as to switch the application of current and the non-application of current to a heater 23. Thus, the temperature in the device is adjusted and the relative moisture is changed by adjusting the temperature. The jamming caused by adhesion, etc., can be prevented from occurring in the image forming device.

Abstract: PURPOSE:To prevent the deterioration in a frictional electrification property and a cleaning failure by allowing a toner to contain polyester obtained by bringing a monomer composite containing aliphatic dialcohol, etc., to polycondensation reaction, as a binding resin. CONSTITUTION:Polyester used as a toner binding resin is polyester obtained by bringing a monomer composite containing three pieces or more of polyvalent monomers, aromatic dicarboxylic acid and aliphatic dialcohol to polycondensation reaction. Especially, since the aliphatic dialcohol is used, flexibility of a molecular chain in polyester becomes satisfactory. Therefore, mechanical energy by stirring a developer, etc. is converted to kinetic energy of the molecular chain of polyester, a mechanical stress which a toner grain receives is relaxed, and a breakdown of the toner grain is prevented. Accordingly, the generation of fine powder caused by the binding resin of the toner grain is suppressed, and the deterioration of a frictional electrification property and a cleaning failure can be prevented.
