Filed: 1994-07-06
Abstract: PURPOSE:To prevent the creep deformation of a developing roller and to obtain an appropriate and excellent image by providing a developing unit, a pulley, a tapered pulley, a belt, a moving part and an elastic part which are respectively specified. CONSTITUTION:In the case the developing roller 4 is stopped, the developing unit 3 is stretched to a toner storing tank side by the elastic part 28, so that the roller 4 is separated from a photoreceptor 1 and the creep deformation is prevented from being caused on the roller 4 even though the roller 4 is left as it is for a long time. In the case the photoreceptor 1 is rotated, the belt 27 is moved to the large-diameter part of the tapered pulley 25 coaxially attached to the photoreceptor 1 and further the peripheral length of the belt is constant, so that the large-diameter part of the pulley 25 is compensated by shortening a distance between the roller 4 and the photoreceptor 1. As a result, the unit 3 is moved to the photoreceptor 1 side and the roller 4 and the photoreceptor 1 are brought into contact with each other at a specified nip interval, whereby toner is stably stuck to the photoreceptor 1 from the roller 4 by rotating the roller 4 and the photoreceptor 1 with low rotational torque.

Title: Semiconductor switching device
Inventor: OIKAWA SABURO
IPC: H01L29/72
Filed: 1985-07-15
Abstract: PURPOSE:To substantially improve the maximum cut of current without increasing the ON voltage by a method wherein the width of a strip-shaped region contained in one line of the coaxial arrangement is formed shallower than the remaining width, and at least one line consisting of a strip-shaped region with regular with is arranged between the center gate current collection electrode and the circumferential gate current collection electrode. CONSTITUTION:If it is assumed that a coaxial multi-arrangement of a thin, strip-shaped cathode-emitter layer structure (unit GTO) whose circumference is surrounded by gate electrodes is called the first line - the 5th line from the side near the center section of the semiconductor substrate, the difference in the speed of the turn-off operation is produced in the third line float gate unit GTO by the difference in the resistance of a gate electrode. And ultimately, the current will be concentrated to the third line line that turns off at last. The unit GTO with narrow N-emitter width capable of improving cut-off resistance is arranged on the third line, and float gates are connected each other. Thus, the cut-off resistance of the unit GTO on the third line is improved much more than that of the other unit GTO line, thereby increasing the maximum cut-off current as a whole.

Title: Printing head position detector in serial printer
Inventor: SUGINO KOICHI
IPC: B41J19/18
Filed: 1989-06-19
Abstract: PURPOSE:To obviate the position detection sensor, facilitate assembling, and reduce the cost by a method wherein drive coils incorporated in a printing head and a magnet generating an induced current in said drive coils are used, the induced current generated in the drive coils is detected by a detection circuit, and the position of the printing head is detected. CONSTITUTION:A printing head 4 is reciprocated along a guide shaft 3. When the printing head 4 reaches, for example, a home position, at least one of drive coils 5 crosses the magnetic flux of a magnet 6. Then, an induced current generated in the drive coil 5 is detected by a detection circuit 8, and a detection signal is outputted. At this time, the printing head 4 is disposed out of a printable range and, therefore, a drive signal is not supplied from a drive circuit 7 to the drive coil 5. In this manner, the detection circuit 8 can properly detect only the induced current. A microcomputer controlling a printer recognizes that the printing head comes to the home position by the detection signal and conducts a required home sensing action.

Title: Method of compensating fuel-injecting property of electronic fuel injection device
Inventor: INOUE HIDEHIKO
IPC: F02D41/34
Filed: 1984-07-25
Abstract: PURPOSE:To reduce the production cost of a fuel injection device, by providing a control circuit with a means for adjusting the quantity of supplied fuel and with a means for compensating the fuel-injecting property of an injector. CONSTITUTION:The quantity of fuel to be supplied to an engine 2 is calculated by a control circuit on the basis of the actions of a revolution speed detector 4 and an operating condition detector 5 so as to send out a signal to drive an injector 3. The ineffective injection time and fuel injection ratio compensation coefficient of the injector 3 are stored in a memory circuit 8. A compensatory calculation circuit 9 compensates the fuel-injecting property of the injector. When the injector 3 is replaced with another one, the adjusting value of the control circuit is altered to a compensatory value corresponding to the latter injector, by a changeover unit 30c. This results in reducing the production cost of a fuel injection device.
