Title: Burst sound communication system
Inventor: TAGUCHI SATORU
IPC: H04B1/713
Filed: 1983-11-22
Abstract: PURPOSE:To avoid the reduction of communication capacity per unit time by dividing a frequency channel into plural subchannels and providing a field intensity deciding means to each divided subchannel to obtain a transmission request identifying means. CONSTITUTION:When each transmission/reception station wants transmission, an identification frequency pair shown by P is transmitted for a second, for example, via a communication circuit. A transmission request identifying circuit 15 identifies an address information signal to own transmission/reception station under the control of an incorporated station identifying program and then transmits the subsequent reception contents to a receiver 16 via an output line 1501 for processing. If a transmission request signal having higher priority than that of the own transmission/reception station exists, a transmission request stop command signal is produced via an output line 1502. Thus each transmission/ reception station has a prescribed priority order and uses the same frequency band via the transmission request signals of different code contents to perform the automatic communication with each desired transmission/reception station by a time division system.

Title: Production of powder tea
Inventor: GOTO HIROSHI
IPC: A23F3/00
Filed: 1992-08-19
Abstract: PURPOSE:To inexpensively produce the powder tea having high drawing efficiency by impact-grinding the tea leaves of raw material into the powdery shape. CONSTITUTION:A rotary disk 14 is rotated at a high rotation rate, while the tips of the respective hammers of the rotation disk keep fine distances from the projections 10 of a lining plate 9. Thereby, the tea leaves of raw material are collided to the projections 10 of the lining plate 9 and simultaneously beaten and impact-ground into the powdery tea. Thus, the tea leaves of raw material are converted into the powder tea comprising fine particles having particle sizes of approximately 3-100mum and having round particle shapes. Further, each particle has a coarse surface and a large surface area due to the impact grinding treatment. Thereby, the drawing efficiency of the powder tea is improved, and the tea can be produced at a low cost, because a small amount of the powder tea may be sealed in a tea bag, when the powder tea is packed in the tea bag and used.
