Title: Image forming device
Inventor: FUKUSHIMA HISASHI
IPC: G03G15/05
Filed: 1983-06-27
Abstract: PURPOSE:To prevent the irregularity of image density by making the arrangement of magnetic poles of a magnetic field generating means correspond to the locus of a light beam that makes on scan on a photosensitive body when said locus scans on the photosensitive body once. CONSTITUTION:The magnetic poles of the rotating magnet in a developing sleeve 32 are so arranged as to obtain the same napping of toner at the time tA when the light beam is at a point A and at the time tB when the beam is at a point B, preventing the toner from varying in density owing to the rotation of the rotating magnet 33 when the light beam scans from the point A to the point B on a photosensitive layer 31. Consequently, the toner of a developer 36 never changes in brush-shaped napping state while the light beam scans from the point A to the point B. The density of the toner is unchanged, so an image free of density irregularity is obtained.

Title: Gear pump and its assembling method
Inventor: OHARA NAOYUKI
IPC: F04C2/18
Filed: 1980-08-19
Abstract: PURPOSE: To offer a compact, inexpensive gear pump with high ejection pressure and simple construction without resorting to machining precision by narrowing a gap between a side panel and gears.  
     CONSTITUTION: A drive gear 15 and its slave gear 16 are mounted in a concavity 18 of a pump case 17. A side panel 25, the end face of which is finished flat, is inserted into the pump case 17 along a cylindrical surface 29 having the end face of the side panel 25 contacted fitly with the side faces of gears 15 and 16. After a cover (not shown in the figure) is tightened, the pump is operated without load by rotating the drive gear 15 with a motor, for instance, which results that only a portion of the side panel 25 contacting with the gears 15 and 16 is ground down to the depth of 0W0.1mm, therefore the circumferential rim of the side panel 25 is contacted fitly with a stage 28 of the pump case 17. This eliminates the gap between the side faces of the gears 15 and 16 and the side panel 25. Thus, a highly efficient, inexpensive and compact gear pump can be offered.

IPC: A61B8/06
Filed: 1993-05-17
Abstract: PURPOSE:To enhance the visuality of speed data by altering the display range of the speed data of a motion fluid displayed on a monitor corresponding to the set value of sampling frequency. CONSTITUTION:The ultrasonic echo signal from the motion fluid in a living body is sampled on the basis of the sampling frequency set to a required range in a PRF setting part 8 and subsequently analyzed by a Doppler analyzing means 3 to calculate speed data (Doppler spectrum) and this speed data is displayed on a monitor 6 by an image display control means 4. When the setting of sampling frequency is altered in the PRF setting part 8, a CPU 9 being a display range altering means, a frame memory 26 and a writing/reading control part 27 change the display range on the monitor 6 displaying the speed data corresponding to the altered value of sampling frequency. At that time, since the display width of the speed data is not changed, the always stable speed data can be confirmed and the visuality of the speed data can be enhanced.

Abstract: PURPOSE:To prevent autonomous self-traveling type working robots from performing any unsuitable actions even when a turning light beam from a light emitter to a certain robot is shielded by the other robot when the plural autonomous self-traveling type working robots are arranged in the same working area. CONSTITUTION:The azimuch of a radiation radiated from a light emitter 1 through one side of an autonomous self-traveling type working robot 6 and the azimuch of a radiation radiated from the light emitter 1 through the other side of the autonomous self-traveling type working robot are calculated by the self-position data of the autonomous self-traveling type working robot 6 and it is identified whether the other autonomous self-traveling type working robot 6 exists in the area sandwiched by these two radiation or not. When the other autonomous self-traveling type working robot 6 exists in this area, it is judged that the autonomous self-traveling type working robot 6 positioned farer than the light emitter 1 exists in a dead angle area where the turning light beam from the light emitter 1 is shielded by the autonomous self-traveling type working robot 6 positioned on the side of the light emitter 1 rather than this robot, and the position of the autonomous self-traveling type working robot 6 is controlled by acquiring that information.

Title: Display device
Inventor: TAKATSU YUJI
IPC: G09F13/00
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To lower the cost by coloring the entire display surface except light emitting diodes nearly equally to a low-visibility light emission color among the colors of the light emitting diodes. SOLUTION: The color of a printed board 4 is close to the green light emission color of a low-visibility light emitting diode 3 among the light emitting diodes 1-3 and printed in dark green in consideration of the contrast of each light emitting diode. The printed board 4 is frosted. Thus, light emission of low-visibility green can be compensated and the visibility is prevented from decreasing owing to the reflection of the sun light by the printed board 4. Further, a hood 5 is also coated in dark green similarly to the printed board 4. Consequently, the light emission of low-visibility green can be compensated and a decrease in the visibility and temperature rises of the light emitting diodes 1-4 owing to the sun light directly impinging on the light emitting diodes 1-3 can be prevented.
