Title: Frequency division synchronizing circuit
Inventor: MAEDA TAKESHI
IPC: H03L7/00
Filed: 1990-07-20
Abstract: PURPOSE:To synchronize with small scale circuit constitution by forming the frequency division synchronization circuit of a phase variable circuit generating a clock synchronously with a reference clock inside of an electronic circuit, and a correction circuit correcting a small delay by the phase variable circuit so as to eliminate a phase shift of an edge part. CONSTITUTION:A reference clock C1 inside of an electronic circuit 9 is inputted to a phase variable circuit 1, which outputs a frequency division clock Co2 frequency-divided by an optional frequency division ratio decided by a frequency divider circuit 2 synchronously with the reference clock C1. Then the frequency division clock Co2 is inputted to an electronic component 7 requiring the input clock and in such a case, the phase of the frequency division clock Co2 is delayed by the reference clock C1 by the passing of the phase variable circuit 1. In order to correct the delay of the phase, the reference clock C1 is inputted to a reference clock correction circuit 5 to generate a reference clock Co1 after phase correction. Then the reference clock Co1 after phase correction is inputted to an electronic component 6 requiring the input clock. Thus, the clock synchronously with the input clock is simply obtained with an optional frequency division ratio.

Abstract: PURPOSE:To precisely control the surface potential of a photosensitive body and to stably set it by separating the measuring cycle from the controlling cycle of the surface potential of the photosensitive body, measuring and holding the surface potential within the optional cycle and controlling the electrostatic charge quantity thereof in the controlling cycle continued from the measuring cycle based on the measured result. CONSTITUTION:In the first measuring cycle M0, the surface potential of the photosensitive body 3 is measured by a potential sensor 4 at timing which is diametrically opposite to a reference potential part 2. Then, in the controlling cycle C0 which is continued from the cycle M0, the surface potential of the photosensitive body is changed. Besides, in the next measuring cycle M1, the surface potential of the photosensitive drum is measured like the above described M0. However, the concerned cycle M1 is not overlapped with the preceding controlling cycle C0 and the stable surface potential of the photosensitive drum after the consecutive surface potential control such as the cycle M0 and the cycle C0. By similarly repeating the consecutive measurement and control such as the measuring cycle Mn and the control cycle Cn, the potential Vp of the photosensitive body is controlled so as to be made to coincide with reference potential Vs regardless of the positional relation between the potential sensor 4 and an electrostatic charger 18.

Filed: 1985-08-29
Abstract: PURPOSE:To make it possible to increase the opening speed and return speed of an armature, in a wire dot printer, by utilizing the compression energy of a spring member as propelling force at the return time of the armature. CONSTITUTION:When a current is applied to a coil 3 in such a state that an open coil 10 is excited and a spring support 14 is attracted to an open core 9, an armature 6 is separated from a yoke 2 to perform opening operation, that is, printing operation by a printing wire 7. After printing, when the current to the coil 3 is cut off in such a state that the open coil 10 is demagnetized and a current is applied to an attraction coil 12 and the support 14 is attracted to an attraction core 11, the armature 6 performs return operation by the attraction force of a permanent magnet 4 but return operation is performed by the elongation of a return spring 13 having stored energy at the same time. By this method, the opening speed and return speed of the armature can be increased and a printing stroke can be made large.

IPC: B22D5/00
Filed: 1990-07-19
Abstract: PURPOSE:To prevent the generation of bad shaped appearance of a mold pig iron by using steam having the specific value or lower of droplet diameter, cooling with atomized water spreading and making the specific temp. or lower of super heat at near surface layer of molten pig iron in the mold before cooling with much water spraying. CONSTITUTION:In this invention, the super heat at near the surface layer of molten pig iron in the mold before cooling with water spreading is made to be >=50 deg.C. In the case of the general casting pig iron, this can apply the well- known cooling method, but in the case of high Si pig iron having >=2.0% Si, as this solidifying temp. is low, the case, which can not cool to the prescribed temp., is developed. In this case, in this invention, by colliding atomized water particles having very fine, such as <=20mum particle size, to a material to be cooled with the air force, sensible heat according to the vaporization of water particles, is utilized. By this method, as the surface of molding pig iron is scarcely wetted and cooling capacity as the same degree as the ordinary water spraying, is obtd., cooling water is not invaded into inner part of the molded pig iron and the bad appearance is not developed.
