Title: Fixing device and image forming device
Inventor: AMITA AKIYASU
IPC: G03G15/20
Filed: 1991-09-18
Abstract: PURPOSE:To execute satisfactory fixing and to reduce curling amount regardless of the kinds of transferring papers. CONSTITUTION:A heat-proof elastic belt 4 is stretched and set to supporting rolls 7a and 7b in a state where they contact to a fixing roller 1, a lever 8 is attached to the end of the core bar 5b of the supporting roll 7b and can turn around a pin 9, and a solenoid 10 on/off controlled by a controlling part 11 is attached to the other end of the lever 8. The detecting signal of a means for detecting whether the transferring paper is a plain paper or an envelope is inputted to the controlling part 11, when an envelope mode is selected, the solenoid 10 is turned on, and the lever 8 turns to be a state shown by a figure. Since the contact width of a belt is widened and the envelope is fully heated, good fixing can be obtained. And when a plain paper mode is selected, the solenoid 10 is turned off, and the lever 8 turns counterclockwise, then the contact width of the belt is narrower than that in the envelope mode, so that the plain paper is not heated more than necessary, therefore, the curling amount can be reduced.

Abstract: PURPOSE:To obtain a stable picture and to improve an operability by adding the output signal of the relative angle of a support body and the output signal of the angular velocity of a tube part to a prescribed gain based on the discriminated result of a photographing mode. CONSTITUTION:A control arithmetic means 14, when a photographing mode discriminating means 13 discriminates to be a still photographing, adds the output signal (c) of a relative angle detection circuit 11 and the output signal (d) of an angular velocity detection circuit 12 and the result obtained by integrating and operating the signal (c) to a first prescribed gain.

Abstract: PROBLEM TO BE SOLVED: To easily manufacture a semiconductor laser having a non-uniform effective period of grating on a waveguide. SOLUTION: A single pitch grating 20 is formed on the main surface of a substrate 10 using an interferential exposing method.

Abstract: PURPOSE:To prevent the effect of external noise and an effect due to the mutual intervention of fellow IC pins by a method wherein the title device is provided with the IC pins, which consist of conductor pins for delivering or receiving an electrical signal from or to an IC chip, an insulator to cover these conductor pins and moreover, conductor jacketings to cover the outside of the insulator. CONSTITUTION:Conductor pins 2 are erected in a through hole 8 of a laminated ceramic container 5 and an insulative synthetic rosin layer 6 is provided in such a way that a solder 9 at the joint of the hole 8 is not exposed. The pins 2 are covered with a ceramic hollow rod 3. Moreover, the exterior of the rod 3 is covered with metal jacketings 4. The metal jacketings for such IC pins are all connected to a conductive film 7. As an IC package is covered with the film 7 almost completely, the effect of external noise can be prevented by connecting the film 7 to arrangement terminals. Moreover, it is evident that the mutual intervention of the fellow IC pins is also weakened. Accordingly, the gaps between the pins are made narrow and a reduction in the size of the whole IC package is also contrived.

Abstract: PURPOSE:To sufficiently melt the lower end of a butt part and to prevent the generation of incomplete fusion by arranging a backing strip with a gap (g) on the rear side of the butt part, putting the tip of a plasma frame on the backing strip and performing welding while extending it. CONSTITUTION:The backing strip 9 is arranged with the gap (g) on the rear side of the butt part.
