Title: Developing device
Inventor: HATSUYAMA CHIYAKO
IPC: G03G15/08
Filed: 1993-10-03
Abstract: PURPOSE:To prevent developer from aggregating in a developer carry path and scattering from a developing device by smoothing developer carry in the developer carry path. CONSTITUTION:The cross-sectional area of a toner supply path 12 is made equal to or smaller than the smallest cross-sectional area of a toner carry path in the developing device 1, the cross-sectional area of an excess-toner carry path 13 is made larger than the smallest cross-sectional area of the toner carry path in the developing device 1. To be concrete, the order of smallest cross-sectional area to the largest cross-sectional area is the toner supply path 12, a toner supply/carry space 9, a communication path, a toner recovery/carry space 10, and the excess-toner carry path 13. Thus, because the toner carry path in the developing device increases in cross-sectional area as it goes downstream, scattering of toner in the toner supply/carry space 9 and clogging of the excess-toner carry path 13 with toner are prevented, and toner carry along the toner carry path in the developing device can be smoothed.

Title: Amplifier
Inventor: NOOMAN JII DEIRUMAN
IPC: H03F3/45
Filed: 1989-10-18
Abstract: PURPOSE: To improve the positive through rate of an amplifier by providing the amplifier with a controllable auxiliary output stage, and when an error signal indicating a large difference between an input signal and an output signal appears, supplying an additional power supply current by the auxiliary output stage. CONSTITUTION: An auxiliary B class output stage 44 consists of a switch FET 46, a 2nd current source FET 48 and a through FET 50. When an error signal applied to the gate of the FET 46 does not exceed a threshold defined by the FET 48, the FET 50 is turned off. When the signal applied to the gate of the FET 46 exceeds the threshold, voltage is impressed to the gate of the FET 50. The FET 50 is turned on and an additional power supply current necessary for the attainment of a high positive through rate is supplied. Since the activated through FET 50 acts so as to compenate a current generated from a load FET 36, the positive through rate is improved.

Title: Light source unit
Inventor: MORIYAMA YOSHIYUKI
IPC: G02B5/02
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To decrease nonuniformity in light by constituting a light diffusion board by changing the form of area adjacent to a light source on the side of light diffusion board facing the light source convex so that the angle of field with the center of light source as point of view can exceed a specified angle. SOLUTION: Concerning the thickness of light nonuniformity removing member 01, its central part is made thick and its peripheral part is made thin. Concerning a light box combining a fluorescent tube 3 and a reflection board 4, the light just above the fluorescent tube 3 is strongest and the more away from the fluorescent tube 3, the more the intensity of light is lowered. Therefore, the light nonuniformity removing member 01 is made thickest just above the fluorescent tube 3 and made thinner toward the peripheral side so that light flux transmitted through the light nonuniformity removing member 01 can become uniform light intensity. Besides, the form of light nonuniformity removing member 01 is projected on the side of fluorescent tube 3.  Thus, since the angle of field θcontrolling the surface reflection of light nonuniformity removing member 01 becomes θ>90 deg. and the surface reflection angle of light flux just above the fluorescent tube 3 is enlarged, more light flux can be allocated to a dark section away from the fluorescent tube 3.

Title: Ballpoint pen and its refill
Inventor: NONAKA RYOICHI
IPC: B43K7/00
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To allow a ballpoint pen to be used at an angle with most writing satisfaction by crossing an axial center of a barrel at an acute angle to a surface including an opening of a ball support assembled with a ball. SOLUTION: An axial center L2 of a barrel is crossed at an acute angle θto a surface A2 including an opening 61a of a ball support 61 by bending an end part of the support 61 associated with a holder 64 in a direction of the center L2 of the barrel. And, a line L3 for connecting a center 61c of the opening 61a of the support 61 to a center 62a of a ball 62 is crossed with the center L2 of the barrel at its nib side. That is, in an optimum using state, the center 62a of the ball 62 is disposed directly above the center L2 of the barrel.  Since the center L2 of the barrel is crossed at the acute angle θ, if this angle is decided as a mean value of favorite inclining angle of a writing instrument in the case of normally using the instrument by a general person, the surface A2 including the opening 61a of the support 61 become substantially parallel in the case of using it by the general person, the instrument can be used at the angle of most writing satisfaction.
