  • Patent number: 10607773
    Abstract: When a powder material (5) is molded by introducing the material into a cavity (11) between a lower punch (2) and a die (1), compression molding the material between upper and lower punches (3 and 2) into a compact (51) of desired shape, and moving up the lower punch (2) to eject the compact (51), a lubricant is applied to the interior surface of the die (1) by fitting a pad (24) around the lower punch (2) and impregnating the pad with the lubricant. Since the lubricant is applied on every molding operation, molding operation can be continuously carried out.

  • Patent number: 9565692
    Abstract: Improvements on latency are achieved for highest priority messaging and channel utilization in a time-slotted access channel structure. New superframe structures are presented where scheduled, but unused access slots can be utilized by secondary nodes. The messaging is accomplished by defining user priorities for nodes and the nodes sensing an ongoing transmission in the network. The time slotted channel access structure has at least one access phase which is divided into access slots. In the beginning of the access phase the nodes sense if a highest priority transmission exist and if not, another node with a lower user priority may initiate transmission.

  • Patent number: 8355748
    Abstract: The overall throughput of the radio communication traffic in a radio communication area in a radio communication environment where a plurality of types of radio communication systems are mixedly used in a neighboring radio communication area is improved. When a multi-mode control station (101) performs communication with a terminal station in a network through a plurality of types of communication systems, a communication link parameter collecting section (10141) collects parameters indicating the states of the communication links. A resource allocation determining section (10143) determines communication resource allocation for which the throughput is the greatest for each resource allocation period according to the parameters. A communication control section (1015) controls a multi-mode communication unit (1012) according to the result of the determination.
