Title: Control circuit for exciting electromagnetic coil
Inventor: KONDO JUNICHI
IPC: H01F7/18
Filed: 1987-11-02
Abstract: PURPOSE:To increase mechanical life with reduced impact noise without impairing accuracy of armature operation by inserting current limiting resistances in series in one end of a full-wave rectifying circuit output, and adding voltage holding capacitors in parallel to both output ends of the resistances. CONSTITUTION:Upon change of a switch 101 toward C2, a relay contact 103' switches to C3 for such time as determined by a capacitance of a capacitor 102, such contact returning to C4 after such time. At this point, in an electromagnetic coil 105 a current charged in a capacitor 2 flows immediately after the contact 103' has been switched to C3, the current value of such current being decreased by a time constant determined by the capacitance of the capacitor 2, such current value being further decreased to one that is made to flow by a voltage in which an output voltage of the full-wave rectifying circuit is divided by a combined impedance of the capacitor 2 and the electromagnetic coil 105 as well as an impedance by a resistance 1. Accordingly, when an armature 24 starts lifting, its current is large, whereas when it reaches a cap 22, its current is small, whereby impact noise can be reduced.

Filed: 1990-10-15
Abstract: PURPOSE:To simplify codes so as to obtain a high compression rate by making it possible to register the initial values of plural dictionaries corresponding to a history state and adopting also the history of precedently appeared character strings for a character string in coding. CONSTITUTION:A dictionary 10 is constituted to a dictionary group consisting of the prescribed number of dictionaries 10-1 to 10-N less than the total number of character sorts to be processed and all the character sorts are initially registered in each of respective dictionaries 10-1 to 10-N by allocating a reference number to each character. At the time of coding an input character string, a specific dictionary 10-i in the dictionary group is specified and coded in accordance with subordination with a precedently coded character string, i.e. index information indicating the history, and when the inputted character string is not registered, a character string obtained by adding the succeeding one character to the reference number of the coded character string is registered as a new reference number. Thus, the initial registration of plural dictionaries can be simplified by collecting the subordination at the time of coding/decoding and the efficiency of coding can be improved.
