Patent JP-H0830108-A (JP)
Title: Image forming device
Inventor: NAKAZAWA NOBUO
IPC: G03G21/14
Filed: 1994-07-15
Abstract: PURPOSE:To prevent an image from being transferred again by a separating charger and to obtain an image of high quality even in the case a loop is formed on the latter half part of a transfer material due to a speed difference between a pair of rollers and an image carrier by reducing a discharge current of the separating charger at a time on and after the leading end of the transfer material reaches a position near a nip part between a pair of fixing rollers. CONSTITUTION:A separation DC high voltage power supply for a high voltage power supply circuit 18 is controlled so that a difference current of a separation may be a constant value, but, in the case toner to be used has a negative charge, retransfer is liable to occur when the negative difference current is increased, on the other hand, defective separation is liable to occur when the negative difference current is decreased. Then, just before the leading end of the transfer material P enters the nip between the fixing rollers 10, the current value is shifted from a proper difference current value to a difference current value side where the defective separation is liable to occur but the retransfer is difficult to occur. The control of shifting the difference current value is not necessary in the case the loop is not formed on the latter half part of the transfer material, or in the case the transfer material is shorter than a distance L1 between the fixation nip R and a transfer point (q).

Title: Motor drive system controlled by phase accumulator and method therefor
Inventor: KLAFFENBACH DAVID KURT
IPC: H02P6/06
Filed: 1998-05-28
Abstract: PROBLEM TO BE SOLVED: To achieve the best printing quality and performance by performing high resolution speed control for closely synchronizing with a process speed of a laser printer, by utilizing it between a binary divider phase accumulator programmable as post divider and a motor control circuit. SOLUTION: A post divider 40 permits the arbitrary division of the output of a phase accumulator 38 with coefficients 2, 3, 4 or let it pass directly (a mode division by 1). By utilizing a binary divider programmable as the post divider 40 between the phase accumulator 38 and a motor control circuit 44, a decrease or deterioration in relative resolution can be minimized to a coefficient of 2 or less over the octave number equal to the number of bits in the binary divider plus 1. Then, the arbitrary divider placed at the output of the phase accumulator 38 has an output frequency and an absolute resolution which decreased by the same coefficient.

Title: Copperplate engraving print and manufacture thereof
Inventor: INOUE MITSUO
IPC: B41M3/14
Filed: 1989-07-21
Abstract: PURPOSE:To obtain a print enabling easily discriminating between genuine and spurious by sticking various functional materials such as glass beads on a print directly after an intaglio printing by the use of an electron beam curing copperplate engraving ink and by irradiating electron beam to the print to stick the functional materials completely on a copperplate engraving depicted line. CONSTITUTION:Directly after the engraving intaglio printing of paper 3 in an electron beam curing ink 1, a pearl pigment 2 is stuck on the whole print. This print is caused to pass through an electron beam irradiator for the purpose of momentarily curing the whole depicted line with the pearl pigment 2 stuck thereon to stick the pearl pigment 2 completely on a copperplate engraving depicted line surface. Because the surface of uncured EB ink 1 has an adhesion sufficient to stick the pearl pigment 2 thereon, the pearl pigment 2 on this depicted line is firmly stuck on the depicted line surface after curing by electron beam irradiation and is excellent in chalking resistance. Such print is difficult to reproduce according to a normal printing method, but this printing method enables obtaining a print being very excellent in forgery-preventing properties.

Title: Electromagnetic pump-controlling apparatus for combustion machine
Inventor: KASADA TOSHIO
IPC: F04B17/04
Filed: 1994-08-09
Abstract: PURPOSE:To burn the fuel in the most suitable state of combustion at all times, by a method wherein when a constant voltage-determining part determines the drop of voltage, a pulse-compensating part compensates a pulse so that the amount of fuel to be supplied becomes constant, either by increasing pulse width or by shortening its cycle. CONSTITUTION:A pulse-presetting part 2 presets a pulse to be applied to an electromagnetic pump 7 on the basis of a signal from a combustion-controlling part 11. A constant voltage-determining part 8 determines whether constant voltage or not by receiving a signal from the pulse-presetting part 2 and by reading a value on a source voltage- -detecting part 4 in a specified time after raising the pulse outputted from the pulse-presetting part 12. When the constant voltage-controlling part 8 determines the drop of voltage, the pulse- compensating part 9 compensates a pulse so that the amount of fuel to be supplied becomes constant either by increasing a pulse width preset by the pulse-presetting part 12 or by shortening its cycle. In this way, the fuel can be burned in the most suitable state of combustion at all times.

Title: Structure of branch part of pipeline
Inventor: SAKURAI YOSHIKI
IPC: F16L41/08
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To improve earthquake resistance of the branch part of a pipeline by providing a snap tap for the purpose of branching a water supply pipe from a water distribution pipe and by enabling this water supply pipe to be attached in the pipe axial direction of the water distribution pipe. SOLUTION: If any relative displacement in the axial direction happens between the ground foundation and a water distribution pipe 1 in the case of an earthquake, with regard to a water supply pipe 2 extending in the pipe axial direction of the water distribution pipe 1, the water distribution pipe 1, a water branching plug 3 and the water supply pipe 2 are displaced in the same direction and in an integrated manner. With regard to a water supply pipe 2b arranged at a right angle to the pipe axial direction of the water distribution pipe 1, any swing motion of the water supply pipe 2b by rendering an elbow part 14 as a fulcrum deforms the water supply pipe 2 near the elbow part 14 so that any shearing force applied to the connection part 2d between the elbow part 14 and the water supply pipe 2b may be absorbed in its deformation.  Accordingly, the water supply pipe 2b is prevented from its release from the elbow part 14 and the connection part 2d between the water supply pipe 2b and the elbow part 14 is prevented from its breakage. Therefore, the earthquake resistance at the branch part in a pipe line is improved.
