For example, toner source materials are compounded by specified proportions, mixed in a Banbury mixed or the like, fused and kneaded, pulverized and classified to produce the toner having about <=30μm average particle size, especially 3 to 20μm. The separated fine particle toner having smaller particle size than the above size is fused or softened by heating in the press extruding machine, and the obtd. fused or softened material is extruded by the extruding machine.  The extruded material is then mixed into the kneaded material after the kneading process and before the cooling process so as to use the fine particle toner again.

Title: Video jitter absorbing method
Inventor: KUROBE AKIO
IPC: H04N19/00
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To effectively absorb video jitter caused by re-transmission. SOLUTION: In the case that video coding is controlled by using both a frame rate and quantization accuracy as parameters so as to compensate the reduction in a transmission effective speed due to a transmission error, quantization control-controls so as not to be deteriorated below a lower limit. That is, 701 as an object function curve is used to obtain setting points on correlation curves at each effective transmission speed. Thus, even when the effective transmission speed is considerably reduced, the quantization accuracy is not deteriorated below β and a generated code amount for one video frame is not extremely small. As the result, storaging of lots of video frames to a reception buffer is prevented during awaiting a re-transmission frame and occurrence of video jitter is suppressed.

IPC: H05K3/34
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To perform excellent soldering work on a printed wiring board for high-density packing by forming a plurality of slits so that the heights of solder mounts formed of solder jetted from the slits on a slit plate can become successively higher in the carrying direction. SOLUTION: The molten solder supplied to a first nozzle from the bottom side with a pump is separately jetted upward through each slit and form a primary wave 18A having three small mounts. As a result, the contact area between the wave 18A and a printed wring board 28 increases and a long dipping distance can be secured while the dipping depth is maintained at an appropriate value. In addition, since the flow of the molten solder in the wave 18A finely and violently changes, the dynamic action of the solder jet increases. Therefore, the components mounted on the board 8 at a high packing density can be surely wetted with the solder by making the solder to flow deep into the interiors of the spaces between the parts. Then the shape of the solder is adjusted appropriately by bringing the solder into contact with a secondary wave 22.
