Title: Manufacture of resin sealed electronic part
Inventor: YOKOYAMA TAKAAKI
IPC: H01L21/56
Filed: 1988-11-01
Abstract: PURPOSE:To form a part of a resin-sealed unit also on another principal surface of a support plate by a method wherein an external lead is interposed by a mold, a first movable mold is made in contact with one of principal surfaces of another end of a support plate while a second movable mold is made into contact with the other principal surface of another end of the support plate, and fluid sealing resin is injected from a resin inlet port into a mold cavity. CONSTITUTION:The other end of a support plate is interposed between first and second movable molds 20, 22 until an almost whole molding cavity 27 is filled with sealing resin 29. This can securely prevent the support plate 2 from tilting during resin molding, thereby efficiently forming a thin resin layer having approximate uniform thickness over an entire area on another principal surface 2b of the support plate. More of the sealing resin 29 is injected in the said principal surface 2b of the support plate where the sealing resin cannot be easily injected. This enables well-balanced injection of the sealing resin 29 into one of principal surfaces 2a and the other principal surface 2b of the support plate 2, thereby excellently forming a resin-sealed unit 31.

Title: Intermittent idle monitor method
Inventor: TANABE KOJI
IPC: H04W72/04
Filed: 1995-10-24
Abstract: PROBLEM TO BE SOLVED: To avoid the occurrence of unnecessary monitoring and the failure of link establishment by setting intermittent time decided by the number of frequencies by which monitoring is executed, time required for monitoring and time when a monitor result becomes valid. SOLUTION: The time 5 of one frame is multiplied by the number of continuous frames required for the monitor result to obtain time 1 required for one frequency monitoring. Then, time 1 required for one frequency monitoring is multiplied by the number of the frequencies for monitoring to obtain time 2 required for all frequency monitoring. At last, time 2 required for all frequency monitoring is subtracted from time 3 when the monitor result becomes valid to obtain time 4 for intermitting monitoring. Monitoring is executed during time 2 required for all frequency monitoring, and a system is set to an idle state during time 4 when monitoring is intermitted. Thus, an intermittent idle monitoring method whose power consumption quantity is small and which has small possibility of failing in link establishment can be realized.
