Title: Device for forming thin layer of developer
Inventor: KAN FUMITAKA
IPC: G03G15/09
Filed: 1983-07-19
Abstract: PURPOSE:To stabilize formation of a thin film of a non-conductive developer by providing a member for holding the developer which has internally a means for generating a magnetic field in the aperture of a vessel for supplying the developer and a member for restraining magnetic particles on the outside therof and rotating the means for generating the magnetic field. CONSTITUTION:Magnetic particles are successively raised by the rotation of a means 4 for generating a magnetic field and a member 2 for holding a developer. Said particles are scraped by a sealing member 8 and are spirally dropped as shown by an arrow (e). The particles take therein the lower nonmagnetic developer of a developer layer 7 during the falling and return to the lower part of a vessel 3 for supplying the developer. Such operation is repeated. The magnetic particles existing in the lower part of the vessel 3 are prevented from emerging to the outside of the vessel 3 by the effect of the magnetic field between the member 5 and the means 4. On the other hand, the nonmagnetic developer can pass through the space between the member 5 and the surface of the member 2 and is thus uniformly and thinly coated on the surface of the member 2. The developer riding on said surface faces the surface of a photosensitive body 1 and is used for development. The thin layer of the nonmagnetic developer is thus uniformly and stably obtd.

Title: Vertical synchronism detector circuit
Inventor: KITAZAWA KEIO
IPC: H04N5/10
Filed: 1978-10-23
Abstract: PURPOSE: To obtain a vertical synchronism detector circuit which is suited for formation into the integrated circuit and can obtain the pulse of the steady phase.  
     CONSTITUTION: The up- and down-counting functions are switched for up-down counter 23 by the composite synchronous pulse applied to up-down switch terminal 24. NAND circuits 26 and 27 plus AND circuit 28 form the circuit which prevents the overflow and underflow of the counter. Furthermore, NAND circuit 27 leads out the control output to vertical pulse generation counter 35. It is not sufficient to transfer and lead out the first-step signals of counter 35 in the sections of the horizontal synchronous pulse and the equalization pulse, and thus the counter is cleared away when the underflow preventing action is given. The pulse duration is ample at the area of the vertical synchronous pulse, and as a result counter 35 is never cleared away for the priod enough to generate the vertical pulse. Thus the clock pulse is led in to obtain the vertical synchronous pulse through output terminal 37.
