Patent EP-0887191-A2 (EP)
Inventor: WAKAHARA SHIROU
IPC: G03G15/05
Filed: 1998-06-25
Abstract: Supporting a control electrode between a toner carrier and
a counter electrode as eliminating warpage and undulation
produced in the control electrode, which includes toner passage
holes (gates) and controls projection of the toner through the
gates. Interposed between the toner carrier (22) and the
counter electrode (24) is the control electrode member (26)
formed with the gates (37) through which the toner flows. The
control electrode member (26) is fixed at a predetermined
position as supported by supporting devices (50) at both ends
of a region which is not involved in the toner projection. In
the supporting device (50), the control electrode member (26)
including an insulating substrate and feeder lines is held
between a supporting member (51) and a fixing member (52), both
members being of a flat configuration and in vertical positional
relation, and fixed with screws (55). The supporting member
(51) is fixed with fixing screws (54) to a support body (53)
retained at a predetermined position so as to apply a force in
a direction of B to the control electrode member (26), thereby
causing the control electrode member (26) to be curved at a
region of the gates (37). The curved region of the gates (37)
accommodates the warpage and undulation of the control
electrode member. The position of the supporting member (51)
is fine-adjusted in a direction of C by an adjusting member (57)
screwed into a central portion of the supporting member (51) 
and by an urging member (58) interposed between a head (57a)
of the adjusting member (57) and a bent portion (53a) of the
support body (53), whereby warpage and undulation extending
over a wide area of the control electrode member (26) is also
eliminated.

Abstract: L'invention concerne un procédé de réduction ou d'élimination de la 'distortion oblique' entre des signaux traversant les conducteurs d'un câble de transmission de données. L'invention concerne aussi des câbles et des installations de transmission de données fonctionnant selon le procédé considéré, de manière à réduire l'obliquité susmentionnée à un niveau acceptable. Le procédé comprend les étapes suivantes : transfert d'un signal, au niveau d'un premier conducteur, depuis ce premier conducteur vers un second conducteur à une position intermédiaire entre les extrémités du câble de transmission de données; et transfert d'un signal, au niveau d'un second conducteur, depuis ce second conducteur vers le premier conducteur à une position intermédiaire entre les extrémités du câble de transmission de données. Le transfert s'effectue de telle manière que, durant la transmission sur la longueur du câble, tout signal est acheminé partiellement sur le premier conducteur et partiellement sur le second conducteur. On peut ainsi réduire ou éliminer sensiblement le phénomène d'obliquité entre les signaux au niveau des conducteurs.

Abstract: A reel stand includes (a) a reel base for engaging a reel and driving the
reel, (b) a bearing disposed in the reel base and being extended through by a
rotary shaft, and (c) a spring being urged to the rotary shaft. This
construction allows the reel stand to integrate a brake torque mechanism into
its downsized body, and to provide a tape with uniform tape tension when the
tape is taken up or supplied. The spring is pressed to the shaft to produce
brake torque, which lowers the peripheral velocity of the shaft. As a result,
less frictional heat is produced, which reduces changes in friction factors due
to the heat.

Abstract: The invention features a method and apparatus for an ink jet recording apparatus in which a
carriage lock is provided. When a return of the carriage to the home position HP is detected, the
waiting time at the home position HP is counted. When this waiting time has reached a
predetermined time, a carriage lock is engaged. When the carriage lock is engaged immediately
after the carriage returns to the home position HP, the frequency of the carriage lock is reduced,
thus enhancing its durability. Further, there is no need of disengaging the carriage lock at a
restart of the printing, thus improving responsiveness at the restart of the printing.

Abstract: An internal combustion engine system is capable of reducing soot and NOx
simultaneously, and prevents the occurrence of an undesirable situation where a
generation amount of soot is increased in accordance with frequent transitions between
a first combustion mode and a second combustion mode. In the system, the first
combustion mode in which an amount of inert gas supplied to the combustion chamber
is larger than an amount of the inert gas that causes the generation amount of soot to
become a peak, such that soot is hardly generated, and a second combustion mode in
which an amount of the inert gas supplied to the combustion chamber is smaller than the
amount of the inert gas that causes the generation amount of soot to become a peak, are
selectively performed. When conditions are such that switching between the first
combustion mode and the second combustion mode has or may occur frequently, the
execution of the first combustion mode is controlled. The frequency of switching can
be determined, for example, based on a frequency of change of the engine load, an
operational state of the engine, or road information.

Abstract: In a mobile communication system which carries out communication
between a base station and a mobile terminal by transmitting a control signal
therebetween, the control signal is augmented in its amplitude with an
increase of a retransmission number of the control signal. The control
signal is delivered from a base station to each base station with a
retransmission number included therein. Each base station detects the
retransmission number of the control signal by a retransmission number
detector and augments an amplitude of the control signal with an increase of
the retransmission number by an amplitude control portion. With this
structure, it is possible to avoid nonreception of the control signal at each
mobile terminal even when the control signal from the base station suffers
interference from another reception energy from a different base station.

Abstract: The present invention eliminates artifacts in an image
formed using a plurality of imaging sources. Visible seams
in the image are eliminated by randomizing the stitch point
(18) between the scan lines (44, 46) produced by each
imaging source. The randomization may be optimized by
additionally applying a method for relocating the random
stitch point (18) based on the data content of the scan
line, adjacent scan lines, and other criteria. The present
invention further compensates for in-scan and cross-scan
errors caused by thermally induced errors, spinner
synchronization errors, mechanical misalignment, and other
factors associated with the use of a plurality of imaging
systems (30). A photodetector system (120, 122, 124),
comprising a mask (124) having a pair of triangular openings

reader may function similar to a conventional mouse, except that the relative motion is sensed
by the imager. The optical code reader may detect the relative movement of artifacts across
its field of view in any arbitrary direction within the focal length setting of the device. The
optical code reader may also be incorporated into a laptop and a pen based computer, and a
PDA. Relative motion may be sensed when moving either the housing or the surface itself, or
both, relative to the other. In the portable data processing embodiments, the optical code
reader may also be utilized as a code reader a video camera, to indicate relative movement
between the device and a surface, and for other various fringing functions. The surface may
