Title: Image forming device
Inventor: AKIYAMA SATORU
IPC: G03G15/043
Filed: 1990-06-27
Abstract: PURPOSE:To dispense with the making of a reference clock frequency into a high frequency even when resolution, etc., goes to high resolution by generating and outputting image transfer clock by frequency-dividing either a reference clock with prescribed frequency selected by a signal selection means or the inversion reference clock of the reference clock with prescribed frequency. CONSTITUTION:When a main scan synchronizing signal is inputted from a signal generating means, a selection means 6 selects either the reference clock with prescribed frequency or the inversion reference clock of the reference clock with prescribed frequency, and outputs it to a 1/4-frequency dividing circuit 8, and a frequency dividing means generates the image transfer clock VDOCLK by frequency-dividing the reference clock with prescribed frequency selected by the selection means or the inversion reference clock of the reference clock with prescribed frequency. Thereby, it is possible to set the maximum value of the quantity DELTAt of deviation between the main scan synchronizing signal BD and the image transfer clock VDOCLK at the half cycle of the reference clock CLK 4.

Abstract: PURPOSE:To blow off the sticking matter of abraded powder, which is formed at the end of the side positioned in the direction of the rotation of the commutator of a brush so as to make the short between commutator pieces hard to occur by forming, at least, the side, positioned in the direction of the commutator, of the brush, irregularly in the axial direction of the brush. CONSTITUTION:One end of a brush 1 is fixed to a plate spring 3, and the other end pressure-contacts with a commutator 2 by the spring force. In this brush 1, plural recesses 11a, 11a... are formed at specified intervals at the sides positioned in the direction of the rotation of the commutator 2.

These recesses 11a, 11a... at the side 11 consist of V or U-shaped grooves parallel with the axis of the commutator 2. When the abrasion of the brush 1 progresses, the sticking matter of abraded powder grows and juts out, but this is so designed that it reaches the recess 11a at the side 11, at the level that it is far smaller than the width of the longitudinal groove 21 of the commutator 2, and hereupon the root part of the sticking matter is abraded out.

Title: Method for starting electroless plating
Inventor: SHIMAUCHI HIDENORI
IPC: C23C18/16
Filed: 1986-07-18
Abstract: PURPOSE:To initiate an electroless plating reaction on an electrically conductive member to be plated without contaminating a plating soln. or requiring an external power source by connecting the member on which electroless plating does not take place or hardly takes place to an active member with a lead wire. CONSTITUTION:An active member A activated by immersion in an active noble metal soln. or other method is immersed in an electroless plating soln. The electric potential of the member A lowers to plating deposition potential in a moment. A member B of copper, stainless steel, titanium, carbon or the like to be plated is then immersed in the plating soln. Since the electric potential of the member B does not lower to plating deposition potential, plating does not proceed. When the members A, B are connected with a lead wire, the electric potential of the member B also lowers to plating deposition potential and a plating reaction is initiated. Thus, activation of the member to be plated before electroless plating is made unnecessary. This method is suitable for the production of hybrid IC.
