Title: Image forming device
Inventor: KAWAGUCHI HIDEJI
IPC: G03G15/16
Filed: 1988-01-30
Abstract: PURPOSE:To obtain an excellent image which has no transfer deviation by setting the hardness and surface friction coefficient of a transfer roller and pressing force on an image carrier to prescribed values, and rotating the image carrier and transfer roller in a mutual slip state. CONSTITUTION:The power of a driving means M is transmitted to the image carrier by a 1st power transmitting means 22a and the power from the driving means M is transmitted to the transfer roller 26 by a 2nd power transmitting means 22b so that the peripheral speed of the transfer roller 26 is faster than that of the image carrier 22. When the hardness and surface friction coefficient of the transfer roller 26 and the pressing force on the image carrier 22 are set to the prescribed values respectively, the image carrier 22 and transfer roller 26 rotate while slipping. Therefore, even if a shock is generated when the front end of a sheet S is caught by a fixing device 11 during printing operation, the photosensitive drum 22 and transfer roller 26 maintain the same speeds. Consequently, a transfer image is prevented from shifting.

Title: Microprocessor
Inventor: AZEKAWA YOSHIIKU
IPC: G06F11/28
Filed: 1990-01-30
Abstract: PURPOSE:To reduce a load in design and to shorten delivery inspection time by supplying a debug supporting function and an exception detecting function to software housed in a memory device selectively. CONSTITUTION:An MPU 4 supplies an exception processing function 3 required for a system that becomes a target and the debug supporting function 2 selectively with the software housed inside or outside the MPU 4. Therefore, it is possible to dispense with the assembling of the functions on a chip as hardware by substituting the exception processing function 3 and the debug function 2 with the software for that performed with the hardware, and also, to increase the degree of freedom for function selection since the function can be switched by re-assembling the software. In such a way, the load in the design can be reduced and the delivery inspection time can be shortened.

Title: Manufacture of silicon avalanche photodiode
Inventor: NAGAI SEIICHI
IPC: H01L31/10
Filed: 1979-02-26
Abstract: PURPOSE: To very easily manufacture a p-type side light incidence planar Si avalanche photodiode, by utilizing the fact that the impurity diffusion velocity in polycrystalline Si is much higher than that in single crystal Si.  
     CONSTITUTION: An annular polycrystalline Si growing nucleus 12 is made of a thin oxide film or the like on an n + -type single crysral Si substrate 1. Epitaxial growth is caused while a p-type impurity is doped into the entire surface, thereby producing a polycrystalline Si layer 13 on the nucleus 12 and a p-type single crystal Si layer 2 on the exposed substrate 1. An n-type impurity is selectively diffused into the layer 13. The layer 13 is all changed into the n-type by utilizing the fact that the diffusion velocity in the layer is high. At the same time, the impurity in the substrate 1 is diffused into the layer 2 to produce an n-type region 9 surrounding the layer 13 and the nucleus 12. A challow p + -type region 3 is thus produced by diffusion in the surface part of the layer 2 while a pn junction is prevented from exerting an influence. An electrode 7 is fitted on the region 3 while a reflection preventing film 14 is coated on the region 3. An insulating film 10 is coated on the surface except for the film 14.

Title: Cleaning device of copying machine
Inventor: NAGASAWA NAOKAZU
IPC: G03G21/10
Filed: 1982-02-15
Abstract: PURPOSE:To prevent toner from sticking a toner guide plate even at high humidity, after long-period disuse, and in case of the staying of much toner, by making the length of a coupling member greater than the distance between the 1st and the 2nd members and allowing the coupling member to strike the guide plate intermittently. CONSTITUTION:The link 7' of the coupling member 7 is longer than the distance between a pin 8 and a rotating shaft 5. The coupling member 7 is suspended with the pin 8, but rotates in the suspended state as the rotating shaft 5 rotates and is inverted around the pin 8 abruptly after a cylinder part is hooked by the rotating shaft. Since the distance between the pin 8 and toner guide plate 4 during the inversion is less than the link 7' of the coupling member 7, so the cylindrical rod member of the coupling member 7 falls on the toner guide plate 4 during the inversion to strike the toner guide plate 4 impulsively. Further, the cylindrical rod member is drawn on the toner guide plate 4 according to the rotation of the rotating shaft 5 to scrape toner on the toner guide plate 4.
